Description

Technical Field

[0001] This utility model relates to the technical field of pouring cup production equipment, and in particular to a powder filling device and a pouring cup dry powder forming system for pouring cups. Background Technology

[0002] Sprue cups are commonly used in metal casting processes. Typically, molten metal is poured into the sprue cup, and then flows through the gating system from the bottom of the sprue cup into the casting cavity. The molten metal cools and solidifies in the casting cavity to obtain a workpiece of a predetermined shape and size.

[0003] Currently, the production process of pouring cups typically involves producing a pouring cup blank, which is then dried and sintered to obtain the pouring cup. The pouring cup blank is usually formed using a traditional press or a casting mold. For pouring cup blanks formed by traditional press, the long-term use of steel molds causes severe wear and tear, which can introduce impurities from the mold and other equipment issues, resulting in a significant reduction in the quality of the pouring cup blank. In addition, the cost of producing pouring cup blanks using traditional press equipment is relatively high.

[0004] Furthermore, to obtain the casting cup blank by casting with a casting mold, it is necessary to first prepare a slurry, then pour the slurry into the mold, keep it warm until the monomer and crosslinking agent have completely reacted to obtain a ceramic green body, and after demolding, obtain the casting cup blank. This involves many processes, resulting in low production efficiency of the casting cup blank.

[0005] To address the aforementioned issues, our R&D team proposed a method for forming sprue cups using dry powder molding. The sprue cup blank is obtained through hydraulic pressing. However, the process of production personnel filling the mold used to form the sprue cup blank with dry powder is not conducive to ensuring the consistency of the injected dry powder amount and is inefficient. Therefore, there is an urgent need for a powder filling device that facilitates the precise filling of a fixed amount of dry powder into the mold. Summary of the Invention

[0006] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a powder filling device for dry powder molding of pouring cups that facilitates filling a quantitative amount of dry powder into a plastic mold; in addition, a dry powder molding system for pouring cups is also provided.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] According to one aspect of this application, a powder filling device for dry powder molding of pouring cups is provided, comprising:

[0009] A molding die placement section is provided for placing a molding die. The molding die has a cavity and an upper opening at its upper end, which communicates with the cavity. A core is installed in the cavity. The portion of the core located in the cavity defines a molded cavity for filling a pouring cup containing high-temperature resistant dry powder. The core extends into the upper opening, and the portion of the core extending into the upper opening defines a dry powder adding channel for adding the high-temperature resistant dry powder into the molded cavity. The dry powder adding channel communicates with the molded cavity.

[0010] A quantitative dry powder measuring device is used to measure a quantitative amount of high-temperature resistant dry powder. The quantitative amount of high-temperature resistant dry powder is used to fill the mold cavity of the molded mold placed on the molded mold placement part to form a molded cup blank.

[0011] A dry powder transfer device is used to transfer a portion of the quantitative high-temperature resistant dry powder located in the quantitative dry powder measuring device and add it to the molding cavity of the pouring cup of the molding mold placed on the molding mold placement part.

[0012] The beneficial effects of this utility model are as follows: In this embodiment, by providing a mold placement part, it is convenient to place the mold on the mold placement part; furthermore, by providing a quantitative dry powder measuring device, it is convenient to measure a quantitative amount of high-temperature resistant dry powder, and one quantitative amount of high-temperature resistant dry powder is used to form one sprue cup blank, which helps to ensure that the amount of dry powder filled into the sprue cup cavity of the mold each time is sufficient and that the amount of dry powder filled is the same, which helps to improve the quality and consistency of the sprue cup blank forming; in addition, by providing a dry powder transfer device, it is convenient to transfer one quantitative amount of high-temperature resistant dry powder located in the quantitative dry powder measuring device and add it to the sprue cup cavity of the mold, which helps to automatically add a quantitative amount of high-temperature resistant dry powder into the sprue cup cavity of the mold, thereby improving the filling efficiency of filling powder into the sprue cup cavity of the mold.

[0013] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0014] According to one embodiment of this application, the quantitative dry powder measuring device is provided in multiple ways, and each of the quantitative dry powder measuring devices is used to measure one portion of the quantitative high temperature resistant dry powder.

[0015] In this embodiment, multiple quantitative dry powder measuring devices are provided, which facilitates the placement of multiple plastic molds on the plastic mold placement part, and allows multiple portions of quantitative high-temperature resistant dry powder to be measured at the same time through multiple quantitative dry powder measuring devices, thereby improving the efficiency of measuring quantitative high-temperature resistant dry powder.

[0016] According to one embodiment of this application, the dry powder transfer device is provided in multiple ways, and the multiple dry powder transfer devices are arranged one-to-one with the multiple quantitative dry powder measuring devices. Each dry powder transfer device is used to transfer a portion of the quantitative high-temperature resistant dry powder from the quantitative dry powder measuring device corresponding to it and add it to the molding cavity of the pouring cup of a molding mold placed on the molding mold placement part.

[0017] In this embodiment, multiple dry powder transfer devices are provided, each corresponding to a different quantitative dry powder measuring device. This allows for the simultaneous transfer of a portion of high-temperature resistant dry powder from each of the multiple quantitative dry powder measuring devices into the mold cavity of a single mold's sprue cup. This facilitates the simultaneous filling of powder into multiple molds, further improving the filling efficiency of powder into the mold cavity of the mold's sprue cup.

[0018] According to one embodiment of this application, the powder filling device for dry powder molding of pouring cups further includes:

[0019] The frame, the molding die placement part is disposed on the frame, and multiple quantitative dry powder measuring devices and multiple dry powder transfer devices are respectively installed on the frame;

[0020] A dry powder adding box is installed on the frame. The dry powder adding box is provided with a dry powder adding cavity for adding the high temperature resistant dry powder. The bottom plate of the dry powder adding cavity is provided with a plurality of dry powder falling outlets at intervals. The plurality of dry powder falling outlets are respectively connected to the dry powder adding cavity.

[0021] The plurality of quantitative dry powder measuring devices include a plurality of quantitative volumetric cylinders, each of which is installed on the lower side of the bottom plate of the dry powder adding box, facing the plurality of dry powder drop outlets. A dry powder receiving cavity is formed inside the quantitative volumetric cylinder. The upper end of the dry powder receiving cavity is connected to the dry powder drop outlets that are positioned opposite it to form a dry powder quantitative cavity for filling the high-temperature resistant dry powder. The dry powder quantitative cavity can hold one portion of the quantitative high-temperature resistant dry powder.

[0022] A dry powder sorting device is movably disposed within the dry powder adding cavity. The dry powder sorting device is used to sort the high-temperature resistant dry powder that is located in the dry powder adding cavity but has not entered the dry powder metering cavity after the dry powder metering cavity is filled with the high-temperature resistant dry powder, so that the high-temperature resistant dry powder that has not entered the dry powder metering cavity avoids the dry powder falling outlet.

[0023] In this embodiment, the bottom plate of the dry powder adding box is provided with multiple dry powder drop outlets at intervals. Multiple metering cylinders are installed on the lower side of the bottom plate of the dry powder adding box, facing the multiple dry powder drop outlets. A dry powder sorting device is movably installed inside the dry powder adding cavity to facilitate the addition of high-temperature resistant dry powder to the dry powder adding box. After the dry powder metering cavity is filled with high-temperature resistant dry powder, the dry powder sorting device sorts the high-temperature resistant dry powder that is located in the dry powder adding cavity but has not entered the dry powder metering cavity, so that the high-temperature resistant dry powder that has not entered the dry powder metering cavity avoids the dry powder drop outlets. This facilitates the transfer of high-temperature resistant dry powder that has been filled into the dry powder metering cavity, thus preventing other high-temperature resistant dry powder from entering the dry powder metering cavity and increasing the amount of dry powder transferred. Furthermore, the multiple metering cylinders installed on the lower side of the bottom plate of the dry powder adding box serve as measuring devices, which has a simple structure and helps to reduce the manufacturing cost of the powder filling device.

[0024] According to one embodiment of this application, the dry powder sorting device is further configured to, during the process of filling the dry powder metering cavity with the high-temperature resistant dry powder, push the high-temperature resistant dry powder located in the dry powder adding cavity toward the dry powder falling outlet, so that the high-temperature resistant dry powder located in the dry powder adding cavity falls into the dry powder metering cavity which is directly opposite the dry powder falling outlet.

[0025] In this embodiment, the dry powder sorting device is also used to push the high-temperature resistant dry powder located in the dry powder adding cavity toward the dry powder falling outlet during the process of filling the dry powder metering cavity with high-temperature resistant dry powder. This facilitates the high-temperature resistant dry powder located in the dry powder adding cavity to fall into the dry powder metering cavity, making it easier to quickly fill the dry powder metering cavity to obtain a quantitative amount of high-temperature resistant dry powder.

[0026] According to one embodiment of this application, the lower end of the quantitative volumetric cylinder is provided with a second dry powder drop outlet; the powder filling device for dry powder molding of the pouring cup further includes:

[0027] A movable sealing component is movably installed on the lower side of the second dry powder discharge port, and the movable sealing component has a blocking position and an open position relative to the second dry powder discharge port. When the movable sealing component is in the blocking position, it blocks the second dry powder discharge port of the multiple metering volume cylinders; when the movable sealing component is in the open position, it opens the second dry powder discharge port of the multiple metering volume cylinders.

[0028] In this embodiment, a movable sealing element is provided to facilitate the control of the opening and closing state of the second dry powder drop port of the metering volumetric cylinder. This allows for the sealing of the second dry powder drop ports of multiple metering volumetric cylinders by the movable sealing element, followed by filling the dry powder metering cavity with high-temperature resistant dry powder to obtain a metered amount of high-temperature resistant dry powder. After obtaining the metered amount of high-temperature resistant dry powder, the movable sealing element is placed in the open position, opening the second dry powder drop port and allowing the high-temperature resistant dry powder filled in the dry powder metering cavity to fall, which facilitates the transfer of the high-temperature resistant dry powder filled in the dry powder metering cavity.

[0029] According to one embodiment of this application, the plurality of dry powder transfer devices include a plurality of dry powder falling guide cylinders, each of the plurality of dry powder falling guide cylinders being directly opposite to a plurality of dry powder falling inlets 2. Each dry powder falling guide cylinder is disposed below the dry powder falling inlet 2 directly opposite to it and located below the movable sealing member. A dry powder falling guide channel is provided inside the dry powder falling guide cylinder. The upper end of the dry powder falling guide channel forms a dry powder falling inlet 3, which is directly opposite to the dry powder falling inlet 2. The lower end of the dry powder falling guide channel forms a dry powder falling inlet 4, which is directly opposite to the dry powder adding channel. The high-temperature resistant dry powder falling from the dry powder falling inlet 4 can fall into the dry powder adding channel directly opposite to the dry powder falling inlet 4.

[0030] In this embodiment, multiple dry powder falling guide cylinders are positioned directly opposite multiple dry powder falling inlets. Each dry powder falling guide cylinder has a dry powder falling guide channel, which facilitates the guidance of the falling direction of the high-temperature resistant dry powder falling from the metering volume cylinder. This helps the falling high-temperature resistant dry powder to accurately fall into the dry powder adding channel of the molding mold placed below the four dry powder falling inlets, thereby accurately filling the mold cavity of the mold's pouring cup.

[0031] According to one embodiment of this application, the powder filling device for dry powder molding of pouring cups further includes:

[0032] The mounting support plate is horizontally installed on the frame. The mounting support plate has multiple dry powder falling ports 5 facing the multiple dry powder falling ports 2. Multiple dry powder falling guide cylinders are installed on the lower side of the mounting support plate, facing the multiple dry powder falling ports 5.

[0033] The movable sealing component is a movable sealing plate, which is horizontally slidably mounted on the upper side of the mounting support plate. The lower end faces of the multiple metering cylinders slide in contact with the upper side of the movable sealing plate. The mounting support plate has multiple dry powder drop outlets six facing each of the multiple dry powder drop outlets two. The movable sealing plate has a sealing position and an open position relative to the mounting support plate and the multiple metering cylinders in the horizontal direction. When the movable sealing plate is in the sealing position, it seals the space between the two dry powder drop outlets two and five facing each other. When the movable sealing plate is in the open position, the two dry powder drop outlets two and five facing each other are connected through the dry powder drop outlets six.

[0034] In this embodiment, the movable sealing plate is horizontally slidably installed on the upper side of the mounting support plate. The lower end faces of multiple quantitative volumetric cylinders slide in contact with the upper side of the movable sealing plate. When the movable sealing plate is in the sealing position, it seals the space between the two dry powder drop ports, achieving simultaneous sealing of the two dry powder drop ports of multiple quantitative volumetric cylinders. Then, high-temperature resistant dry powder is filled into the dry powder quantitative cavity to obtain a quantitative amount of high-temperature resistant dry powder. After obtaining the quantitative amount of high-temperature resistant dry powder, the movable sealing plate is placed in the open position. The two dry powder drop ports, one and five, are connected through the six dry powder drop port, achieving simultaneous conduction between them. This allows the high-temperature resistant dry powder filled in the dry powder quantitative cavity to fall, facilitating the simultaneous transfer of the high-temperature resistant dry powder filled in the dry powder quantitative cavity.

[0035] According to one embodiment of this application, the dry powder falling guide cylinder includes a telescopic cylinder and a connecting cylinder. The connecting cylinder is connected to the lower end of the telescopic cylinder. The upper end of the telescopic cylinder forms the dry powder falling port three, and the lower end of the connecting cylinder forms the dry powder falling port four. The telescopic cylinder is installed on the lower side of the mounting support plate, facing one of the dry powder falling ports five respectively.

[0036] The powder filling device for dry powder molding of pouring cups also includes:

[0037] A movable connecting plate is horizontally arranged on the lower side of the mounting support plate. The movable connecting plate is provided with multiple clearance openings facing multiple dry powder falling openings. The connecting cylinders are respectively connected to the movable connecting plate and pass downward through the clearance openings.

[0038] A vertical movement drive device is installed on the frame. The vertical movement drive device is provided with a vertical movement drive part. The movable connecting plate is connected to the vertical movement drive part and can be raised and lowered in the vertical direction under the drive of the vertical movement drive part.

[0039] In this embodiment, the dry powder falling guide cylinder includes a telescopic cylinder and a connecting cylinder. The telescopic cylinder is installed on the lower side of the mounting support plate, facing a dry powder falling port five. The connecting cylinder is connected to the movable connecting plate and passes downward through the clearance port. The movable connecting plate is connected to the vertical movement drive unit, which facilitates the vertical movement drive unit to drive the movable connecting plate to rise and fall in the vertical direction. The telescopic cylinder adapts to the extension and retraction, thereby adjusting the height of the lower end of the connecting cylinder. This is beneficial for adjusting the lower end of the connecting cylinder to align with and be aligned with the dry powder falling port four of the plastic mold placed below the dry powder falling port four. This is beneficial for the falling high-temperature resistant dry powder to be accurately filled into the mold cavity of the mold's pouring cup. After the mold is filled with powder, the connecting cylinder can be lifted, which is beneficial for transferring the mold with the powder filled to the next station.

[0040] According to another aspect of this application, a dry powder molding system for a pouring cup is provided, comprising:

[0041] A molding die assembly station, which is used to assemble the molding die to obtain the molding die;

[0042] The powder filling station is equipped with the powder filling device for forming dry powder in the pouring cup.

[0043] The sealing station is used to seal the upper opening of the plastic mold containing a portion of the quantitative high-temperature resistant dry powder by means of the upper sealing cover, so that a closed cavity is formed in the mold cavity of the pouring cup of the plastic mold containing a portion of the quantitative high-temperature resistant dry powder.

[0044] A locking station, wherein the locking station is used to lock the sealed plastic mold by a locking mechanism;

[0045] A molding die conveying mechanism is used to sequentially convey the molding die placed on the molding die placement part to the molding die assembly station, the powder filling station, the sealing station and the locking station;

[0046] A hydraulic pressurizing device includes a hydraulic pressurizing box with a hydraulic pressurizing chamber inside. The locked plastic mold is placed in the hydraulic pressurizing chamber. Under the hydraulic pressurization action in the hydraulic pressurizing chamber, the locked plastic mold undergoes elastic deformation to extrude a portion of the quantitative high-temperature resistant dry powder located in the mold cavity of the pouring cup to obtain the pouring cup blank.

[0047] The dry powder molding system for the sprue cup in this embodiment includes a mold assembly station, a powder filling station, a sealing station, and a locking station. The powder filling station is equipped with the aforementioned powder filling device for dry powder molding of the sprue cup. This facilitates the assembly of the mold at the mold assembly station, the addition of a fixed amount of high-temperature resistant dry powder into the sprue cup cavity of the mold at the powder filling station via the powder filling device, the sealing of the mold at the sealing station by sealing the upper opening of the mold containing the fixed amount of high-temperature resistant dry powder with an upper sealing cap, thus forming a sealed cavity within the sprue cup cavity of the mold containing the fixed amount of high-temperature resistant dry powder, and the locking mechanism at the locking station for locking the sealed mold. This ensures that the sealed mold, when placed in the hydraulic pressure chamber, undergoes inward elastic deformation under hydraulic pressure. Furthermore… In this embodiment, a mold conveying mechanism is provided to facilitate the sequential transfer of the mold placed on the mold placement section to the mold assembly station, powder filling station, sealing station, and locking station. Furthermore, the locked mold is placed in the hydraulic pressure chamber, where it undergoes elastic deformation under hydraulic pressure to compress a fixed amount of high-temperature resistant dry powder within the casting cup molding cavity, thus obtaining the casting cup blank. This embodiment eliminates the need for slurry preparation, and the filling of high-temperature resistant dry powder is convenient and the hydraulic pressure is highly efficient. Moreover, compared to traditional press molding, the components of the casting cup dry powder molding system in this embodiment experience less wear, which helps reduce the occurrence of impurities that could affect the quality of the molded casting cup blank, thereby improving the production efficiency of the casting cup blank and enhancing the quality of the casting cup.

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0061] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] One aspect of this application provides a powder filling device for dry powder molding of pouring cups, such as... Figures 1 to 11 As shown, it includes:

[0064] The molding mold placement part is used to place the molding mold 3. The molding mold 3 has a cavity inside. The upper end of the molding mold 3 has an upper opening 36, which communicates with the cavity. A core 32 is installed in the cavity. The part of the core 32 located in the cavity defines a mold cavity for filling a pouring cup with high-temperature resistant dry powder. The core 32 extends into the upper opening 36. The part of the core 32 extending into the upper opening 36 defines a dry powder adding channel for adding high-temperature resistant dry powder into the mold cavity of the pouring cup. The dry powder adding channel communicates with the mold cavity of the pouring cup.

[0065] A quantitative dry powder measuring device is used to measure a quantitative high-temperature resistant dry powder. The quantitative high-temperature resistant dry powder is used to fill the mold cavity of the mold 3 placed on the mold placement part to form a mold blank.

[0066] The dry powder transfer device is used to transfer a portion of high-temperature resistant dry powder located in the quantitative dry powder measuring device and add it to the molding cavity of the pouring cup of the molding mold 3 placed on the molding mold placement section.

[0067] In this embodiment, as Figures 1 to 8 As shown, in this embodiment, a mold placement section is provided to facilitate the placement of the mold 3 on the mold placement section. Furthermore, a quantitative dry powder measuring device is provided to facilitate the measurement of a quantitative amount of high-temperature resistant dry powder. One quantitative amount of high-temperature resistant dry powder is used to form one pouring cup blank, which helps to ensure that the amount of dry powder filled into the pouring cup cavity of the mold 3 is sufficient and consistent each time, thus improving the quality and consistency of the pouring cup blank molding. In addition, a dry powder transfer device is provided to facilitate the transfer of one quantitative amount of high-temperature resistant dry powder located in the quantitative dry powder measuring device to the pouring cup cavity of the mold 3. This allows the dry powder transfer device to automatically add the quantitative amount of high-temperature resistant dry powder into the pouring cup cavity of the mold 3, improving the filling efficiency of filling the powder into the pouring cup cavity of the mold 3.

[0068] In this embodiment, as Figure 8As shown, the molding mold 3 in this embodiment includes a molding body 30, a lower sealing block 31, a core 32, and an upper sealing block 34. The molding body 30 has a cavity inside, and the lower end of the molding body 30 has a lower opening that communicates with the cavity. The upper end of the molding body 30 has an upper opening 36 that communicates with the cavity, and the lateral width of the lower opening is not less than the maximum lateral width of the cavity. The lower sealing block 31 is movably installed in the lower opening and can seal the lower opening. The core 32 is installed in the cavity, and the lower end of the core 32... The upper sealing block 34 is placed on the upper side of the lower sealing block 31 and is movably installed in the upper opening 36 to seal the upper opening 36. Before the quantitative high-temperature resistant dry powder is filled, the upper sealing block 34 is not installed in the upper opening 36. The inner side wall of the cavity, the outer side wall of the core 32, the upper side of the lower sealing block 31 and the lower side of the upper sealing block 34 define a closed sprue cup molding cavity for filling the high-temperature resistant dry powder. After the quantitative high-temperature resistant dry powder is filled, the upper sealing block 34 is installed in the upper opening 36.

[0069] Furthermore, such as Figure 8 As shown, in this embodiment, the molding body 30, the lower sealing block 31, and the upper sealing block 34 are all made of elastic material, specifically rubber. In this embodiment, the lower sealing block 31 is installed with an interference fit to the lower opening, and the inner wall of the lower opening presses against the outer wall of the lower sealing block 31, sealing the gap between the lower sealing block 31 and the lower opening. Similarly, in this embodiment, the upper sealing block 34 is installed with an interference fit to the upper opening 36, and the inner wall of the upper opening 36 presses against the outer wall of the upper sealing block 34, sealing the gap between the upper sealing block 34 and the upper opening 36. Furthermore, in this embodiment, the lower sealing block 31 is specifically pressed into the lower opening using a tool, and the upper sealing block 34 is specifically pressed into the upper opening 36 using a tool.

[0070] Furthermore, such as Figure 8 As shown, in this embodiment, both the lower opening and the upper opening 36 are circular through-holes, and both the lower sealing block 31 and the upper sealing block 34 are frustum structures. Furthermore, the shapes of the lower opening and the upper opening 36 in this embodiment can also be configured in other ways. The structures of the lower sealing block 31 and the upper sealing block 34 can be reasonably adjusted according to the shapes of the lower opening and the upper opening 36, so that the lower sealing block 31 can seal the lower opening, and the upper sealing block 34 can also seal the upper opening 36. Furthermore, there are other ways to achieve a seal between the lower sealing block 31 and the lower opening, and other ways to achieve a seal between the upper sealing block 34 and the upper opening 36.

[0071] Furthermore, in this embodiment, the molding body 30, the lower sealing block 31, and the upper sealing block 34 in the molding mold 3 are all made of elastic material. Alternatively, only the molding body 30 can be made of elastic material. Under the extrusion of external force, only the molding body 30 will undergo elastic deformation. The elastic deformation of the molding body 30 can extrude the high-temperature resistant dry powder located in the molding cavity of the pouring cup to obtain the pouring cup blank.

[0072] In this embodiment, as Figure 8 As shown, first, the core 32 is installed on the lower sealing block 31, and the lower sealing block 31 is installed in the lower opening to seal the lower opening. Then, the core 32 is located in the cavity. The inner wall of the cavity, the outer wall of the core 32, and the upper side of the lower sealing block 31 define a filling cavity. A quantitative amount of high-temperature resistant dry powder is added into the formed filling cavity through the upper opening 36. Then, the upper sealing block 34 is installed in the upper opening 36 to seal the upper opening 36. The inner wall of the cavity, the outer wall of the core 32, the upper side of the lower sealing block 31, and the lower side of the upper sealing block 34 define a sealed sprue cup molding cavity. The high-temperature resistant dry powder is filled in the sealed sprue cup molding cavity. Then, the molding mold 3 filled with high-temperature resistant dry powder is placed in the hydraulic pressure chamber of the hydraulic pressure device, and the molding mold 3 is pressurized by hydraulic pressure.

[0073] Furthermore, such as Figure 8 As shown, the core 32 includes a truncated cone portion 322, a cylindrical portion 321, and a truncated cone expansion portion 323. The upper end of the truncated cone portion 322 is the small diameter end, and the lower end of the truncated cone portion 322 is the large diameter end. The cylindrical portion 321 is connected to the small diameter end of the truncated cone portion 322 and extends vertically upward. There is a gap between the outer wall of the cylindrical portion 321 and the small diameter end of the cavity to form a dry powder addition passage for the passage of high-temperature resistant dry powder. The small diameter end of the truncated cone expansion portion 323 is connected to the large diameter end of the truncated cone portion 322, and the large diameter end of the truncated cone expansion portion 323 abuts against the upper side of the lower sealing block 31. This makes it easier to make the lower end of the formed gating cup blank larger and the upper end smaller, so that the formed gating cup blank can be taken out from the molding body 30 through the lower opening.

[0074] In this embodiment, as Figure 8 As shown, the cavity is conical, and the core 32 includes a frustum 322, a cylindrical portion 321, and an expanded frustum 323. The sprue cup molding cavity formed between the outer wall of the core 32, the upper side of the lower sealing block 31, and the lower side of the upper sealing block 34 is a funnel-shaped cavity, which is beneficial for obtaining a sprue cup blank with a funnel-shaped structure. In this embodiment, the sprue cup blank is funnel-shaped. The sprue cup blank is not illustrated in this embodiment. In addition, the cavity and core 32 in this embodiment can be configured with other structures as needed for the structure of the sprue cup blank.

[0075] In this embodiment, as Figure 8 As shown, both the lower sealing block 31 and the upper sealing block 34 are made of elastic material and can undergo elastic deformation under pressure. The upper end of the cylindrical part 321 extends into the upper opening 36. The lower side of the upper sealing block 34 is provided with a relief groove 35 opposite to the cylindrical part 321, and the upper end of the cylindrical part 321 can extend into the relief groove 35. There is a gap between the upper end face of the cylindrical part 321 and the upper sidewall of the relief groove 35. Furthermore, the inner sidewall of the cavity is provided with at least one annular protrusion 301 opposite to the truncated cone part 322. The annular protrusion 301 is horizontally arranged and protrudes towards the truncated cone part 322, so that the extruded casting cup blank can form an inwardly recessed annular groove corresponding to the position of the annular protrusion 301. In addition, in this embodiment, the inner sidewall of the cavity is provided with two annular protrusions 301 opposite to the truncated cone part 322. The two annular protrusions 301 are arranged at intervals in the vertical direction.

[0076] Furthermore, such as Figure 8 As shown, the lower end of the core 32 is connected to a centering positioning protrusion 324. The vertical center line of the centering positioning protrusion 324 coincides with the vertical center line of the core 32. The upper side of the lower sealing block 31 is provided with a positioning groove corresponding to the centering positioning protrusion 324. The centering positioning protrusion 324 is installed in the positioning groove. The centering positioning protrusion 324 limits the vertical center line of the core 32 placed in the cavity to coincide with the vertical center line of the cavity in the circumferential direction, which is beneficial to limit the core 32 to the center position of the cavity.

[0077] In this embodiment, as Figure 8 As shown, the molding die 3 also includes a centering and positioning structure. The centering and positioning structure is installed in the cavity. The centering and positioning structure limits the upper part of the core 32 placed in the cavity in the vertical direction, and limits the vertical center line of the core 32 placed in the cavity to coincide with the vertical center line of the cavity. Thus, at the same height position in the vertical direction, the distance between the outer wall of the core 32 and the inner wall of the cavity is consistent.

[0078] In this embodiment, as Figures 1 to 4 , Figure 7As shown, the molding die placement part in this embodiment includes a molding die placement seat 2, which is a rectangular plate-shaped structure. The molding die placement seat 2 has multiple molding body placement limiting grooves 24 and a lower sealing block placement limiting groove 23. The lower sealing block placement limiting groove 23 is located below the molding body placement limiting groove 24 and communicates with it. The molding die placement seat 2 has multiple lower clearance openings 22. The clearance opening 22 is located below the lower sealing block placement limiting groove 23 and is connected to the lower sealing block placement limiting groove 23; in this embodiment, both the molding body placement limiting groove 24 and the lower sealing block placement limiting groove 23 are hollow cylinders, and the outer diameter of the molding body placement limiting groove 24 is larger than the outer diameter of the lower sealing block placement limiting groove 23; in this embodiment, the lower clearance opening 22 is a circular through opening, and the outer diameter of the lower clearance opening 22 is smaller than the outer diameter of the lower sealing block placement limiting groove 23.

[0079] One embodiment of this application, such as Figures 1 to 3 As shown, there are multiple quantitative dry powder measuring devices, each of which is used to measure a specific amount of high-temperature resistant dry powder.

[0080] In this embodiment, as Figures 1 to 3 As shown, the quantitative dry powder measuring device in this embodiment is provided with multiple devices, which facilitates the placement of multiple plastic molds 3 on the plastic mold placement part, and facilitates the measurement of multiple portions of quantitative high-temperature resistant dry powder by multiple quantitative dry powder measuring devices at the same time, thereby improving the measurement efficiency of quantitative high-temperature resistant dry powder.

[0081] One embodiment of this application, such as Figures 1 to 3 As shown, there are multiple dry powder transfer devices, each corresponding to a number of quantitative dry powder measuring devices. Each dry powder transfer device is used to transfer a portion of high-temperature resistant dry powder from its corresponding quantitative dry powder measuring device and add it to the sprue cup of a mold 3 placed on the mold placement section.

[0082] In this embodiment, as Figures 1 to 3 As shown, this embodiment has multiple dry powder transfer devices, each corresponding to a different quantitative dry powder measuring device. This allows for the simultaneous transfer of a portion of high-temperature resistant dry powder from each of the multiple quantitative dry powder measuring devices into the mold cavity of a mold 3. This facilitates the simultaneous filling of multiple molds 3 with powder, further improving the filling efficiency of the powder into the mold cavity of the mold 3.

[0083] One embodiment of this application, such as Figures 1 to 4 , Figures 9 to 11As shown, the powder filling device for dry powder molding of pouring cups also includes:

[0084] The frame 1 has a molding die placement section, and multiple quantitative dry powder measuring devices and multiple dry powder transfer devices are respectively installed on the frame 1.

[0085] A dry powder adding box 6 is installed on the frame 1. The dry powder adding box 6 is provided with a dry powder adding cavity 60 for adding high temperature resistant dry powder. Multiple dry powder falling outlets 601 are spaced apart on the bottom plate of the dry powder adding cavity 60. The multiple dry powder falling outlets 601 are respectively connected to the dry powder adding cavity 60.

[0086] Multiple quantitative dry powder dispensing devices include multiple quantitative volumetric cylinders 66. The multiple quantitative volumetric cylinders 66 are installed on the lower side of the bottom plate of the dry powder adding box 6, facing multiple dry powder drop outlets 601. A dry powder receiving cavity is formed inside the quantitative volumetric cylinder 66. The upper end of the dry powder receiving cavity is connected to the dry powder drop outlet 601 that is facing it to form a dry powder quantitative cavity for filling high temperature resistant dry powder. The dry powder quantitative cavity can hold one quantitative amount of high temperature resistant dry powder.

[0087] The dry powder sorting device is movably installed inside the dry powder adding cavity 60. After the dry powder metering cavity is filled with high-temperature resistant dry powder, the dry powder sorting device is used to sort the high-temperature resistant dry powder that is located in the dry powder adding cavity 60 but has not entered the dry powder metering cavity, so that the high-temperature resistant dry powder that has not entered the dry powder metering cavity avoids the dry powder falling outlet 601.

[0088] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the bottom plate of the dry powder adding box 6 is provided with multiple dry powder drop outlets 601 at intervals. Multiple metering cylinders 66 are installed on the lower side of the bottom plate of the dry powder adding box 6, directly opposite the multiple dry powder drop outlets 601. A dry powder sorting device is movably arranged inside the dry powder adding cavity 60 to facilitate the addition of high-temperature resistant dry powder to the dry powder adding box 6. After the dry powder metering cavity is filled with high-temperature resistant dry powder, the dry powder sorting device removes the dry powder that is located in the dry powder adding cavity 60 but has not entered the dry powder metering cavity. The high-temperature resistant dry powder is sorted so that any high-temperature resistant dry powder that has not entered the dry powder metering chamber avoids the dry powder drop outlet 601. This facilitates the transfer of high-temperature resistant dry powder already filled in the dry powder metering chamber, preventing other high-temperature resistant dry powder from entering the dry powder metering chamber and thus avoiding an increase in the amount of dry powder transferred. Furthermore, multiple metering cylinders 66 installed on the lower side of the bottom plate of the dry powder adding box 6 serve as measuring devices, which have a simple structure and help reduce the manufacturing cost of the powder filling device. In addition, the dry powder transfer device in this embodiment can be a powder extraction pump or other powder transfer equipment.

[0089] In this embodiment, as Figures 9 to 11 As shown, the frame 1 in this embodiment includes a support base plate 10, a horizontal support beam 12, a horizontal support beam 13, and multiple support columns 11. The multiple support columns 11 are vertically connected to the upper side of the support base plate 10, and the upper ends of the multiple support columns 11 are respectively connected to the horizontal support beam 12 and the horizontal support beam 13. In this embodiment, the middle of the horizontal support beam 12 and the horizontal support beam 13 are connected to multiple support columns 17. The multiple support columns 17 are respectively connected to the upper side of the horizontal support beam 12 and the horizontal support beam 13 and extend vertically upward. The upper part of the multiple support columns 17 is connected to a support frame 18. The support frame 18 has a rectangular frame structure, and the upper side of the support frame 18 is connected to multiple support columns 19.

[0090] In this embodiment, as Figures 9 to 11 As shown, in this embodiment, the dry powder adding box 6 is mounted on multiple support columns 19 via multiple bent connecting plates 61. The bent connecting plates 61 are L-shaped and are provided with bolt through holes 611. The top of the support columns 19 is provided with bolt holes. The bent connecting plates 61 are mounted on the support columns 19 via bolts. The other end of the bent connecting plates 61 is welded to the dry powder adding box 6.

[0091] In this embodiment, as Figures 9 to 11 As shown, the dry powder sorting device in this embodiment includes a horizontal telescopic drive mechanism and a dry powder sorting plate. The dry powder sorting plate is installed in the dry powder adding cavity 60 of the dry powder adding box 6. The dry powder sorting plate is connected to the horizontal telescopic drive mechanism and can move horizontally in the dry powder adding cavity 60 under the drive of the horizontal telescopic drive mechanism. The lower end of the dry powder sorting plate slides against the inner bottom wall of the dry powder adding box 6.

[0092] Furthermore, such as Figures 9 to 11 As shown, the horizontal telescopic drive mechanism in this embodiment includes a telescopic cylinder 64 and a telescopic cylinder 65. The dry powder sorting plate includes a dry powder sorting plate 62 and a dry powder sorting plate 63. The telescopic cylinder 64 is horizontally mounted on the mounting base 182 connected to the support frame 18 and is located on the front side of the dry powder adding box 6. The cylinder push rod 641 provided on the telescopic cylinder 64 passes through the mounting base 182 and the front side plate of the dry powder adding box 6. The cylinder push rod 641 extends into the dry powder adding cavity 60. The dry powder sorting plate 62 is connected to the rear end of the cylinder push rod 641.

[0093] Furthermore, the telescopic cylinder 2 65 is horizontally mounted on the mounting base 4 182 connected to the support frame 18 and located on the rear side of the dry powder adding box 6. The cylinder push rod 2 651 provided on the telescopic cylinder 2 65 passes forward through the mounting base 4 182 and through the rear side plate of the dry powder adding box 6. The cylinder push rod 2 651 extends into the dry powder adding cavity 60. The dry powder sorting plate 2 63 is connected to the front end of the cylinder push rod 2 651. The dry powder sorting plate 2 63 is parallel to the dry powder sorting plate 1 62.

[0094] Furthermore, such as Figures 1 to 4 As shown, in this embodiment, multiple dry powder drop outlets 601 are arranged in a row. The dry powder adding cavity 60 in this embodiment is provided with a dry powder drop guide slope 602. The dry powder drop guide slope 602 is located between two adjacent rows of dry powder drop outlets 601. The high-temperature resistant dry powder filled in the dry powder adding cavity 60 can slide down along the dry powder drop guide slope 602 to the dry powder drop outlets 601 on both sides, which is conducive to the high-temperature resistant dry powder in the dry powder adding cavity 60 entering the dry powder drop outlets 601. In this embodiment, the dry powder drop guide slope 602 extends in the front-back direction and has a triangular structure. The dry powder drop guide slope 602 can also be set in other structures.

[0095] Furthermore, such as Figure 1 and Figure 4 As shown, in this embodiment, the inner wall of the dry powder adding cavity 60 is provided with an inclined slope 1, which slopes from left to right from high to low. The inner wall of the dry powder adding cavity 60 is provided with an inclined slope 2, which slopes from right to left from high to low. This facilitates the entry of the high-temperature resistant dry powder located on the left and right sides of the dry powder adding cavity 60 into the dry powder falling outlet 1 601.

[0096] Furthermore, such as Figure 1 and Figure 4 As shown, in this embodiment, the lower part of the dry powder sorting plate 62 is provided with a plurality of dry powder pushing protrusions 1 spaced apart. The dry powder pushing protrusions 1 are adapted to abut against the inner bottom wall of the dry powder adding cavity 60. In this embodiment, the lower part of the dry powder sorting plate 63 is provided with a plurality of dry powder pushing protrusions 2 621 spaced apart. The dry powder pushing protrusions 2 621 are adapted to abut against the inner bottom wall of the dry powder adding cavity 60. The dry powder sorting plate 62 and the dry powder sorting plate 63 in this embodiment have the same structure.

[0097] Furthermore, such as Figures 1 to 4As shown, the dry powder sorting plate 62, driven by the telescopic cylinder 64, pushes the high-temperature resistant dry powder located in the dry powder adding cavity 60 in the front-back direction. The dry powder sorting plate 63, driven by the telescopic cylinder 65, also pushes the high-temperature resistant dry powder located in the dry powder adding cavity 60 in the front-back direction. After the dry powder metering cavity is filled with high-temperature resistant dry powder, the dry powder sorting plate 62 and the dry powder sorting plate 63 can gather the high-temperature resistant dry powder located in the dry powder adding cavity 60 between the two rows of dry powder falling outlets 601 in the front-back direction, so that the high-temperature resistant dry powder that has not entered the dry powder metering cavity avoids the dry powder falling outlets 601.

[0098] In this embodiment, as Figures 1 to 3 As shown, the quantitative volumetric cylinder 66 in this embodiment has a hollow cylindrical structure, and the dry powder discharge port 601 is a circular through hole. The inner diameter of the dry powder discharge port 601 is equal to the inner diameter of the quantitative volumetric cylinder 66. The upper end of the quantitative volumetric cylinder 66 is connected to a connector 661, which is bolted to the bottom plate of the dry powder adding box 6. Alternatively, the connector 661 can be welded to the bottom plate of the dry powder adding box 6.

[0099] One embodiment of this application, such as Figures 1 to 4 As shown, the dry powder sorting device is also used to push the high-temperature resistant dry powder in the dry powder adding cavity 60 toward the dry powder falling outlet 601 during the process of filling the dry powder metering cavity with high-temperature resistant dry powder, so that the high-temperature resistant dry powder in the dry powder adding cavity 60 falls into the dry powder metering cavity that is directly opposite the dry powder falling outlet 601.

[0100] In this embodiment, as Figures 1 to 4 As shown, the dry powder sorting device in this embodiment is also used to push the high-temperature resistant dry powder in the dry powder adding cavity 60 toward the dry powder falling port 601 during the process of filling the dry powder metering cavity with high-temperature resistant dry powder, thereby facilitating the high-temperature resistant dry powder in the dry powder adding cavity 60 to fall into the dry powder metering cavity, so as to quickly fill the dry powder metering cavity to obtain a quantitative amount of high-temperature resistant dry powder.

[0101] Furthermore, such as Figures 1 to 4As shown, the dry powder sorting plate 62, driven by the telescopic cylinder 64, pushes the high-temperature resistant dry powder located in the dry powder adding cavity 60 in the front-back direction. The dry powder sorting plate 63, driven by the telescopic cylinder 65, also pushes the high-temperature resistant dry powder located in the dry powder adding cavity 60 in the front-back direction. The dry powder sorting device is also used to, during the process of filling the dry powder metering cavity with high-temperature resistant dry powder, push the high-temperature resistant dry powder in the dry powder adding cavity 600, which is located between two rows of dry powder falling outlets 601 in the front-back direction, towards the dry powder falling outlets 601, thus facilitating the falling of the high-temperature resistant dry powder in the dry powder adding cavity 60 into the dry powder falling outlets 601. It should be noted that, in this embodiment, the area in the dry powder adding cavity 60 where the high-temperature resistant dry powder is added is the area between the dry powder sorting plate 62 and the dry powder sorting plate 63.

[0102] One embodiment of this application, such as Figure 1 , Figure 6 As shown, the lower end of the quantitative volumetric cylinder 66 is provided with a dry powder drop outlet; the powder filling device for dry powder molding of the pouring cup also includes:

[0103] The movable sealing component is movably installed on the lower side of the dry powder discharge port 2, and the movable sealing component has a blocking position and an open position relative to the dry powder discharge port 2. When the movable sealing component is in the blocking position, it blocks the dry powder discharge port 2 of multiple metering volume cylinders 66; when the movable sealing component is in the open position, it opens the dry powder discharge port 2 of multiple metering volume cylinders 66.

[0104] In this embodiment, as Figure 1 , Figure 6 As shown, in this embodiment, a movable sealing element is provided to facilitate the control of the opening and closing state of the dry powder falling port two of the metering volume cylinder 66. This allows for the sealing of the dry powder falling ports two of multiple metering volume cylinders 66 by the movable sealing element, followed by filling the dry powder metering cavity with high-temperature resistant dry powder to obtain a metered amount of high-temperature resistant dry powder. After obtaining the metered amount of high-temperature resistant dry powder, the movable sealing element is placed in the open position, opening the dry powder falling port two and allowing the high-temperature resistant dry powder filled in the dry powder metering cavity to fall, which facilitates the transfer of the high-temperature resistant dry powder filled in the dry powder metering cavity.

[0105] In this embodiment, the movable sealing component can also be a switch valve. The switch valve is installed at the lower end of the metering volume cylinder 66, and the metered high-temperature resistant dry powder sealed in the metering volume cylinder 66 is transferred through the switch valve.

[0106] One embodiment of this application, such as Figures 1 to 4As shown, the multiple dry powder transfer devices include multiple dry powder falling guide cylinders 91, each of which is directly opposite to multiple dry powder falling ports 2. Each dry powder falling guide cylinder 91 is located below the dry powder falling port 2 it is directly opposite and below the movable sealing member. The dry powder falling guide cylinder 91 is provided with a dry powder falling guide channel. The upper end of the dry powder falling guide channel forms a dry powder falling port 3, which is directly opposite to the dry powder falling port 2. The lower end of the dry powder falling guide channel forms a dry powder falling port 4, which is directly opposite to the dry powder adding channel. The high-temperature resistant dry powder falling from the dry powder falling port 4 can fall into the dry powder adding channel that is directly opposite to the dry powder falling port 4.

[0107] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, multiple dry powder falling guide cylinders 91 are positioned directly opposite multiple dry powder falling outlets 2. The dry powder falling guide cylinders 91 are provided with dry powder falling guide channels, which facilitates the guidance of the falling direction of the high-temperature resistant dry powder falling from the quantitative volume cylinder 66. This helps the falling high-temperature resistant dry powder to accurately fall into the dry powder adding channel of the molding mold 3 placed below the four dry powder falling outlets, thereby accurately filling the mold cavity of the pouring cup of the molding mold 3 with the falling high-temperature resistant dry powder.

[0108] One embodiment of this application, such as Figures 1 to 4 As shown, the powder filling device for dry powder molding of pouring cups also includes:

The mounting support plate 7 has multiple dry powder drop outlets 6 directly opposite to the multiple dry powder drop outlets 2. The movable sealing plate 8 has a sealing position and an open position in the horizontal direction relative to the mounting support plate 7 and the multiple quantitative volumetric cylinders 66.

When the movable sealing plate 8 is in the open position, the two dry powder drop outlets 2 and 5 directly opposite to it are connected through the dry powder drop outlets 6.

[0111] In this embodiment, as Figures 1 to 4As shown, in this embodiment, the movable sealing plate 8 is horizontally slidably installed on the upper side of the mounting support plate 7. The lower end faces of multiple quantitative volumetric cylinders 66 slide in contact with the upper side of the movable sealing plate 8. When the movable sealing plate 8 is in the sealing position, the movable sealing plate 8 will block the dry powder falling port two and dry powder falling port five that are directly opposite each other, so as to simultaneously block the dry powder falling port two of multiple quantitative volumetric cylinders 66. Then, high-temperature resistant dry powder is filled into the dry powder quantitative cavity to obtain quantitative high-temperature resistant dry powder. After obtaining quantitative high-temperature resistant dry powder, the movable sealing plate 8 is placed in the open position. The dry powder falling port two and dry powder falling port five that are directly opposite each other are connected through the dry powder falling port six, so as to simultaneously conduct the connection between the dry powder falling port two and dry powder falling port five, so that the high-temperature resistant dry powder filled in the dry powder quantitative cavity falls, which is conducive to the simultaneous transfer of the high-temperature resistant dry powder filled in the dry powder quantitative cavity.

[0114] Furthermore, such as Figures 1 to 4 As shown, the horizontal movement drive device in this embodiment includes a telescopic cylinder 84. The telescopic cylinder 84 is horizontally mounted on a mounting seat 5 connected to the support frame 18 and located in front of the movable sealing plate 8. An extension connecting plate 82 is connected to the front of the movable sealing plate 8, and a connecting seat 83 is connected to the front end of the extension connecting plate 82. In this embodiment, a cylinder push rod 841 provided on the telescopic cylinder 84 passes through the mounting seat 5 to the rear. The connecting seat 842 is connected to the rear end of the telescopic cylinder 84, and the connecting seat 842 is connected to the connecting seat 83 by bolts, thereby connecting the movable sealing plate 8 and the telescopic cylinder 84. Furthermore, there are two extension connecting plates 82 and two telescopic cylinders 84 in this embodiment.

[0115] Furthermore, such as Figure 1As shown, the upper side of the mounting support plate 7 in this embodiment is provided with a guide groove, which extends in the front-back direction. The lower side of the movable sealing plate 8 is directly opposite to the guide rail 80 provided on the upper side of the mounting support plate 7. The guide rail 80 extends into the guide groove. In this embodiment, there are two guide grooves and two guide rails 80.

[0116] Furthermore, such as Figure 1 As shown, in this embodiment, the upper side of the movable sealing plate 8 is provided with a limiting groove 81 facing the plurality of quantitative volumetric cylinders 66. The limiting groove 81 extends in the front-back direction, and the lower end faces of the plurality of quantitative volumetric cylinders 66 located in the same row in the front-back direction slide against the bottom wall of the limiting groove 81. In this embodiment, the plurality of quantitative volumetric cylinders 66 are arranged in four rows in the left-right direction, and the limiting groove 81 in this embodiment has four grooves.

[0120] A vertical movement drive device is installed on the frame 1. The vertical movement drive device is equipped with a vertical movement drive part. The movable connecting plate 9 is connected to the vertical movement drive part and can be raised and lowered in the vertical direction under the drive of the vertical movement drive part.

[0121] In this embodiment, as Figures 1 to 3 , Figure 5 and Figure 6As shown, the dry powder falling guide cylinder 91 in this embodiment includes a telescopic cylinder 911 and a connecting cylinder 912.

The telescopic cylinder 911 can adapt to the extension and retraction, thereby adjusting the height of the lower end of the connecting cylinder 912. This is beneficial for adjusting the lower end of the connecting cylinder 912 so that the dry powder falling port 4 is close to and aligned with the dry powder adding channel of the molding mold 3 placed below the dry powder falling port 4. This is beneficial for the falling high-temperature resistant dry powder to be accurately filled into the molding cavity of the pouring cup of the molding mold 3. After the molding mold 3 is filled with powder, the connecting cylinder 912 can be lifted, which is beneficial for the molding mold 3 that has been filled with powder to be transferred to the next station.

[0123] In this embodiment, as Figure 6 As shown, the dry powder falling guide cylinder 91 in this embodiment includes a dry powder dispersing cylinder 913. The dry powder dispersing cylinder 913 is installed inside the connecting cylinder 912 via a connecting support rod 914. The upper end of the dry powder dispersing cylinder 913 is provided with a dry powder dispersing head 9131.

[0124] Furthermore, such as Figure 6 As shown, the dry powder dispersing head 9131 in this embodiment is conical, and the top cone of the dry powder dispersing head 9131 coincides with the vertical center line of the connecting cylinder 912 in the vertical direction; in this embodiment, multiple connecting support rods 914 are provided circumferentially, one end of the connecting support rod 914 is connected to the inner side wall of the connecting cylinder 912, and the other end of the connecting support rod 914 is connected to the outer side wall of the dry powder dispersing cylinder 913.

[0129] The powder filling station is equipped with a powder filling device for forming dry powder in the pouring cup.

[0130] The sealing station and the sealing and locking station are used to seal the upper opening 36 of the plastic mold 3 containing a certain amount of high temperature resistant dry powder through the upper sealing cover, so that a closed cavity is formed in the mold cavity of the pouring cup of the plastic mold 3 containing a certain amount of high temperature resistant dry powder.

[0131] The locking station is used to lock the sealed plastic mold 3 through the locking mechanism;

[0132] The plastic mold conveying mechanism is used to sequentially convey the plastic mold 3 placed on the plastic mold placement part to the plastic mold assembly station, the powder filling station, the sealing station and the locking station.

[0134] In this embodiment, as Figures 9 to 11 As shown, the dry powder molding system for the sprue cup in this embodiment includes a mold assembly station, a powder filling station, a sealing station, and a locking station. The powder filling station is equipped with the aforementioned powder filling device for dry powder molding of the sprue cup. This facilitates the assembly of the mold 3 at the mold assembly station, the addition of a fixed amount of high-temperature resistant dry powder into the sprue cup cavity of the mold 3 via the powder filling device at the powder filling station, the sealing of the upper opening 36 of the mold 3 containing the fixed amount of high-temperature resistant dry powder via the upper sealing cap at the sealing station, thus forming a sealed cavity within the sprue cup cavity of the mold 3 containing the fixed amount of high-temperature resistant dry powder, and the locking of the sealed mold 3 via the locking mechanism at the locking station. This ensures that the sealed mold 3, after being placed in the hydraulic pressurization chamber, undergoes inward elastic deformation under hydraulic pressure. In this embodiment, a molding mold conveying mechanism is provided to facilitate the sequential transfer of the molding mold 3 placed on the molding mold placement section to the molding mold assembly station, powder filling station, sealing station, and locking station. Furthermore, the locked molding mold 3 is placed in the hydraulic pressure chamber, where it undergoes elastic deformation under hydraulic pressure to extrude a fixed amount of high-temperature resistant dry powder within the casting cup molding cavity, thus obtaining the casting cup blank. In this embodiment, slurry preparation is unnecessary, and filling with high-temperature resistant dry powder is easy and the hydraulic pressure is highly efficient. Moreover, compared to traditional press molding, the components of the casting cup dry powder molding system in this embodiment experience less wear, which helps reduce the occurrence of impurities that affect the quality of the molded casting cup blank, thereby improving the production efficiency of the casting cup blank and enhancing the quality of the casting cup.

[0135] In this embodiment, as Figures 9 to 11 As shown, the molding die assembly station in this embodiment is provided with an upper limit plate 14. The upper limit plate 14 is suspended on the frame 1 by a connector. When the upper molding die 3 placed in the molding die placement part moves directly below the upper limit plate 14, a molding die receiving cavity is formed between the lower side of the upper limit plate 14 and the molding die placement part. The upper side of the upper molding die 3 placed in the molding die placement part is attached to the lower side of the upper limit plate 14.

[0136] Furthermore, such as Figures 9 to 11 As shown, in this embodiment, two support columns 122 are spaced apart on the horizontal support beam 12, and two support columns 133 are spaced apart on the horizontal support beam 13. The two support columns 133 are positioned opposite the two support columns 122. The upper end of the support column 122 is connected to a horizontal support block 1, and the upper end of the support column 133 is connected to a horizontal support block 1331. The upper limit plate 14 is installed on the upper side of the horizontal support block 1 and the horizontal support block 1331 by bolts.

[0137] In this embodiment, as Figures 9 to 11 As shown, the molding die assembly station in this embodiment is also provided with a pushing device for pushing and installing the lower sealing block 31. The pushing device is installed on the frame 1 and located below the upper limit plate 14. The pushing device includes a pushing drive mechanism and a pushing boss 161. The molding die placement part is specifically a molding die placement seat 2. The pushing boss 161 is provided with multiple lower clearance openings 22 provided on the molding die placement seat 2. The lower clearance openings 22 are circular openings. The pushing boss 161 has a cylindrical structure. Under the drive of the pushing drive mechanism, the pushing boss 161 moves upward through the lower clearance openings 22 and pushes the lower sealing block 31 in the lower sealing block placement limiting groove 23 of the molding die placement seat 2 located between the lower side of the upper limit plate 14 and the molding die placement part upward, so that the lower sealing block 31 is installed with an interference fit with the lower opening.

[0138] Furthermore, such as Figures 9 to 11 As shown, the push-drive mechanism in this embodiment includes a telescopic cylinder 15, and multiple telescopic cylinders 15 are provided. Specifically, two mounting support beams 111 are connected to the upper part of two sets of support columns 11 that are directly opposite each other in the left and right directions at the plastic mold assembly station. Three horizontal mounting plates 112 are installed between the two mounting support beams 111. In this embodiment, there are five telescopic cylinders 15. One telescopic cylinder 15 is installed on the horizontal mounting plate 112 located in the middle position, and two telescopic cylinders 15 are installed on the other two horizontal mounting plates 112 respectively. The cylinder push rods 151 provided on the telescopic cylinders 15 extend vertically upward. The top of the five cylinder push rods 151 are connected to the push-boom mounting plate 16. Multiple push-booms 161 are directly opposite multiple lower clearance openings 22 and connected to the upper side of the push-boom mounting plate 16 and extend vertically upward.

[0139] In this embodiment, as Figures 9 to 11 As shown, the frame 1 in this embodiment includes a support base plate 10, a horizontal support beam 12, a horizontal support beam 13, and multiple support columns 11. The multiple support columns 11 are vertically connected to the upper side of the support base plate 10, and the upper ends of the multiple support columns 11 are respectively connected to the horizontal support beam 12 and the horizontal support beam 13. The left and right sides of the plastic mold placement seat 2 are provided with guide rails 20 facing the guide grooves 121 and 231. The guide rails 20 are installed in the guide grooves 121 and 231 so that the plastic mold placement seat 2 can be slidably installed between the guide grooves. Two racks 21 are connected to the lower side of the plastic mold placement seat 2. The two racks 21 are parallel and facing each other in the left and right directions.

[0140] In this embodiment, as Figures 9 to 11As shown, the molding die conveying mechanism includes a rotary drive motor 4 and a rotary drive motor 5. Multiple rotary drive motors 4 and 5 are provided. Multiple mounting seats 1 are connected to the lower side of the horizontal support beam 12. Multiple mounting seats 2 132 are connected to the lower side of the horizontal support beam 13, aligned with the multiple mounting seats 1. A rotating shaft 1 on the rotary drive motor 4 passes through the mounting seat 1 to the right, and a rotating shaft 2 on the rotary drive motor 5 passes through the mounting seat 2 132 to the left. On the left side of the rotating shaft 1, a rack 21 is fitted with incomplete gears 40 that mesh with the rack 21. On the rotating shaft 2, opposite the rack 21 on the right side, incomplete gears 50 that mesh with the rack 21 are fitted. In this embodiment... Two rotary drive motors 4 and 5, which are directly opposite each other in the left-right direction, move synchronously. The toothed and toothless parts of the incomplete gears 40 and 50 mounted on the two rotary drive motors 4 and 5, respectively, overlap in the left-right direction. When the rotary shafts 1 and 2 rotate, when the toothed parts of the incomplete gears 40 and 50 mesh with the teeth 211 on the rack 21, the incomplete gears 40 and 50 drive the mold placement seat 2 to move along the guide groove 121 and the guide groove 231. Alternatively, the mold transfer mechanism can also use other drive devices to facilitate the movement of the mold placement seat 2.

[0141] Furthermore, such as Figures 9 to 11 As shown, in this embodiment, both the front and rear ends of the guide groove 121 and the guide groove 221 are open. The mold placement seat 2 is inserted into the guide groove 121 and the guide groove 221 from the front end of the guide groove 121 and the guide groove 22131. The mold placement seat 2 moves backward under the drive of the incomplete gear 140 and the incomplete gear 250.

[0142] In this embodiment, at the locking position, two clamps respectively clamp the upper and lower ends of the molding body 30. Under the clamping action of clamp one, the upper end of the molding body 30 undergoes elastic deformation inward, pressing against the upper sealing block 34 installed in the upper opening 36. This improves the sealing performance of the gap between the upper sealing block 34 and the upper opening 36, preventing water leakage. Additionally, under the clamping action of clamp two, the lower end of the molding body 30 undergoes elastic deformation inward, pressing against the lower sealing block 31 installed in the lower opening. This also improves the sealing performance of the gap between the lower sealing block 31 and the lower opening, preventing water leakage. Furthermore, the molding body 30 has a hollow cylindrical structure. In this embodiment, the clamps are annular clamps, which are not illustrated in this embodiment.

[0143] In this embodiment, as Figures 9 to 11As shown, the dry powder molding system for the pouring cup also includes a mold placement station. The mold placement station places the lower sealing block 31, which is installed with the core 32, in the lower sealing block placement limiting groove 23, and places the mold body 30 in the mold body placement limiting groove 24. The core 32, which is installed with the lower sealing block 31, extends into the cavity of the mold body 30. In this embodiment, the first mold placement seat 2 located at the front is located in the mold placement station.

[0144] In this embodiment, as Figures 9 to 11 As shown, the plastic mold 3 located at the plastic mold assembly station does not have a centering positioning ring 33 and an upper sealing block 34 installed. In the plastic mold assembly station, the lower sealing block 31 is used to be installed into the lower opening with an interference fit. The lower sealing block 31 in the plastic mold 3 located at the powder filling station is installed into the lower opening with an interference fit. The plastic mold 3 forms an upper open pouring cup molding cavity. In this embodiment, the second plastic mold placement seat 2 located from the front to the rear is located in the plastic mold assembly station.

[0145] In this embodiment, at the powder filling station, a fixed amount of high-temperature resistant dry powder is filled into the mold cavity of the upward-opening mold 3's pouring cup. In this embodiment, the third mold placement seat 2, located from front to back, is situated within the powder filling station. Furthermore, at the sealing station, after the centering positioning ring 33 is installed, a sealing block 34 is installed, forming a sealed cavity within the mold cavity of the mold 3's pouring cup containing a fixed amount of high-temperature resistant dry powder. Furthermore, at the locking station, two clamps are used to clamp the upper and lower ends of the mold body 30 respectively, thereby locking the mold 3. In this embodiment, sealing and locking the mold 3 can be done manually, or a sealing device and a locking device can be used separately.

[0146] In this embodiment, the molding body 30, lower sealing block 31, and upper sealing block 34 in the molding mold 3 are all made of rubber material. The hydraulic pressure applied to the molding mold 3 in this embodiment is 85 MPa. The 85 MPa hydraulic pressure applies pressure to the molding mold 3 from multiple directions, causing elastic deformation under the hydraulic pressure in the hydraulic pressurization chamber to extrude the high-temperature resistant dry powder in the mold cavity of the sprue cup to obtain the sprue cup blank. In addition, the hydraulic pressure setting can be reasonably adjusted according to the specifications of the sprue cup blank to be formed and the deformation that the molding mold 3 needs to generate, so as to ensure that the extruded sprue cup blank is qualified.

[0147] It should be noted that the hydraulic pressurizing device is not illustrated in this embodiment, nor is the hydraulic pressurizing box inside the hydraulic pressurizing device illustrated. The specific structure of the hydraulic pressurizing device can be referred to in the prior art hydraulic pressurizing equipment, and will not be described in detail here.

[0148] Furthermore, in this embodiment, a hydraulic pressurizing device is used to pressurize the molding mold 3, achieving uniform pressure on the molding mold 3 and facilitating adjustment of the pressurizing pressure. This causes the molding mold 3 to deform under hydraulic pressure and reliably extrude the high-temperature resistant dry powder filled into the sealed sprue cup cavity. The high-temperature resistant dry powder in the sprue cup cavity is then compressed by the side walls of the sprue cup cavity to obtain the sprue cup blank. Alternatively, other suitable pressurizing devices can be used to pressurize the molding mold 3, ensuring that the high-temperature resistant dry powder in the sprue cup cavity is compressed by the side walls of the sprue cup cavity to obtain the sprue cup blank.

[0149] In this embodiment, after the molding mold 3 is pressurized, it is removed from the hydraulic pressurization chamber. The deformation of the molding mold 3 under external pressure is restored, and the formed sprue cup blank is located in the sprue cup molding cavity. By removing the lower sealing block 31 and the upper sealing block 34, and then applying pressure to the core 32 from the top, the core 32 is moved out from the lower opening. Then, the sprue cup blank located in the sprue cup molding cavity is removed.

[0150] It should be noted that in this embodiment, the size of the molded cavity of the pouring cup is larger than the size of the molded pouring cup blank. The mold 3 undergoes elastic deformation, and the side wall of the molded cavity of the pouring cup is squeezed to fill the high-temperature resistant dry powder in the molded cavity of the pouring cup, so that the high-temperature resistant dry powder is compacted and pressed. After the pressure is released, the molded pouring cup blank retains the molded structure. After the molded pouring cup blank is taken out, it is sintered to obtain a high-temperature resistant pouring cup.

[0151] Furthermore, the dry powder molding system for the pouring cup in this embodiment also includes a control unit. The hydraulic pressurizing device, the first rotary drive motor 4, the second rotary drive motor 5, and each telescopic cylinder are respectively connected to the control unit, which controls the operating conditions of the hydraulic pressurizing device, the first rotary drive motor 4, the second rotary drive motor 5, and each telescopic cylinder. The dry powder molding system for the pouring cup also includes a driving air source system, and each telescopic cylinder is connected to the driving air source system through an air circuit. In addition, the relevant control technologies for controlling the first rotary drive motor 4, the second rotary drive motor 5, and each telescopic cylinder through the control unit can also refer to the existing technology, and will not be described in detail here.
