Description

Technical Field

[0001] This invention belongs to the field of casting cup forming technology, specifically relating to a casting cup forming machine for casting. Background Technology

[0002] Casting gating cup forming machines are mainly used to produce gating cups required in the casting process. Gating cups play a crucial role in the casting process, guiding molten metal into the mold, ensuring uniform metal filling, and helping to remove gases and impurities. Key features of casting gating cup forming machines include: High-temperature resistance: Due to the high temperatures involved in the casting process, the forming machine needs to be made of high-temperature resistant materials to prevent damage in high-temperature environments. Precise control: Forming machines are typically equipped with advanced temperature and pressure control systems to ensure that the size and shape of the gating cups meet requirements. Production efficiency: Modern casting gating cup forming machines are usually highly automated, enabling rapid mold changes and continuous production, thereby improving production efficiency. Versatility: Many forming machines can adapt to the production of different types of gating cups, meeting diverse market demands.

[0003] Casting cup forming machines are widely used in industries such as automobiles, machinery, and aerospace. Especially in the large-scale production of castings, they can significantly improve production efficiency and product quality. Currently, there are various types of casting cup forming machines on the market, but most of them have overly simple structural designs. In the operation of existing casting cup forming machines, special sand is manually poured into the mold, then smoothed by a scraper, and finally the forming head is driven by a hydraulic mechanism to press the special sand in the mold into shape. Although this simple structural design can complete the pressing and forming of the casting cup, the formed casting cup has many burrs, which require manual simple shaping afterward. This is not only time-consuming and labor-intensive, but also affects the overall production efficiency and product quality to a certain extent. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a casting cup forming machine.

[0005] The technical solution adopted to solve the above technical problems is: a casting cup forming machine, including a fixed frame, a processing platform fixedly connected to the fixed frame, and a casting cup forming mold fixedly installed in the middle of the processing platform; The bottom of the fixed frame is fixedly equipped with a material ejection mechanism that matches the casting cup forming mold, and the rear end of the top of the processing platform is fixedly equipped with a material feeding mechanism. A hydraulic drive mechanism is installed at the top center of the fixed frame, and a lifting limit mechanism is also slidably installed on the fixed frame, with the movable end of the hydraulic drive mechanism fixedly connected to the lifting limit mechanism. The bottom end of the hydraulic drive mechanism is fixedly equipped with a molding and pressing mechanism that matches the casting cup molding mold, which is used for pressing and molding the casting cup. A control mechanism for controlling the molding machine is installed on one side of the top of the processing platform.

[0006] Furthermore, the fixed frame includes a fixed base, and each of the top corners of the fixed base is fixedly connected to a support column, and the top of the multiple support columns is fixedly connected to a fixed top plate.

[0007] Through the above technical solution, the fixed frame serves as a support frame, which mainly plays a supporting role, while multiple support columns can guide and limit the lifting and lowering of the lifting and limiting mechanism.

[0008] Furthermore, the casting cup forming mold includes a mold body fixedly installed at the top center of the processing platform, a support base plate fixedly installed at the bottom of the mold body, a plurality of evenly distributed limiting holes on the periphery of the support base plate, a forming groove at the top center of the mold body, and a through ejection groove at the bottom of the forming groove.

[0009] Through the above technical solution, the casting cup molding mold is one of the key components of casting cup molding. It can be fixedly installed on the processing platform by bolts, which can not only ensure stable connection and fixation, but also facilitate installation and disassembly. The bottom of the mold body is fixedly installed with a separable support base plate, which is mainly used to cooperate with the molding pressing mechanism to support and limit the bottom end of the molding pressing mechanism. The middle part of the mold body is provided with a molding groove and a material ejection groove. When special sand is poured into the molding groove and smoothed, the hydraulic drive mechanism will drive the molding pressing mechanism to move downward, thereby cooperating with the mold body to complete the rapid pressing and molding of the casting cup.

[0010] Furthermore, the unloading mechanism includes a support frame fixed to the bottom of the fixed frame, an unloading cylinder fixedly installed on the support frame, a support block fixedly connected to the top of the piston rod of the unloading cylinder, and a plurality of evenly distributed unloading rods fixedly connected to the top periphery of the support block, with unloading columns fixedly connected to the top of the plurality of unloading rods.

[0011] Through the above technical solution, the ejector mechanism is mainly used for automatic ejection of the pouring cup after molding. After the pouring cup is pressed and molded, the piston rod of the ejector cylinder will drive the multiple ejector rods and ejector columns at its top to move upward synchronously through the support block. In this way, the ejector columns can be used to push the molded pouring cup out of the molding groove, which makes it convenient for the staff to pick up the material. After the ejection is completed, the ejector cylinder will drive it to automatically reset.

[0012] Furthermore, the top ends of the plurality of ejector rods respectively pass through corresponding limiting holes, and the ejector rods slide within the ejector groove.

[0013] The above technical solution facilitates the ejection of the molded sprue cup using multiple ejector rods and ejector columns at their tops.

[0014] Furthermore, the feeding mechanism includes a fixed bracket fixed to the rear end of the top of the processing platform. Movable guide rails are fixedly connected to both sides of the top of the fixed bracket. Movable slides are slidably connected to the two movable guide rails. A connecting plate is fixedly connected to the front end between the two movable slides. Two fixed columns are fixedly connected to the top of the two movable slides. A feeding tray is fixedly connected to the top of the multiple fixed columns. A semi-circular slot is opened at the front end of the feeding tray. A mounting base is also fixedly connected to the top of the fixed bracket. A drive cylinder is fixedly installed at the rear end of the mounting base. The front end of the piston rod of the drive cylinder is fixedly connected to the connecting plate.

[0015] Through the above technical solution, the feeding mechanism is used to assist in feeding special sand. During the processing of the pouring cup, the hydraulic drive mechanism first drives the molding and pressing mechanism to move into the mold of the pouring cup to complete the pre-preparation. Then, the piston rod of the drive cylinder will start to extend forward, and then the connecting plate will drive the entire feeding plate to move towards the mold body until it moves to the designated feeding position. Then, the special sand as raw material can be poured onto the feeding plate by manual labor, special conveying mechanism or robot. At this time, the special sand will automatically pour along the inclined surface of the feeding plate and finally fill the molding groove. When the feeding work is completed, the feeding mechanism will quickly reset. At this time, the operator can smooth the special sand in the mold body.

[0016] Furthermore, the hydraulic drive mechanism includes a hydraulic cylinder fixed to the center of the top of the fixed frame, and a fixed connecting seat is fixedly connected to the bottom end of the piston rod of the hydraulic cylinder. The fixed connecting seat has multiple evenly distributed mounting holes on its top periphery.

[0017] Through the above technical solution, the hydraulic drive mechanism serves as the main power unit in the pressing and molding process of the pouring cup. When working, the piston rod of the hydraulic cylinder moves downward, which in turn drives the lifting limit mechanism and the molding pressing mechanism to move downward synchronously through the fixed connecting seat. Then, the molding pressing mechanism works in conjunction with the pouring cup molding mold to complete the pressing and molding of the pouring cup.

[0018] Furthermore, the lifting and limiting mechanism includes a lifting slide mounted on a fixed frame, a connecting column fixedly connected to the bottom center of the lifting slide, an installation groove between the lifting slide and the connecting column, and the fixed connecting seat fixed in the installation groove by screws.

[0019] Through the above technical solution, the lifting limit mechanism is mainly used for auxiliary limiting and precise guidance during the lifting process of the molding and pressing mechanism. Since the lifting slide is located between multiple support columns, it can ensure the processing accuracy of the molding and pressing mechanism during the working process, prevent it from shifting in position or angle, and thus ensure the overall processing quality of the pouring cup.

[0020] Furthermore, the molding and pressing mechanism includes a main molding seat, in which a primary telescopic rod is slidably installed, and a secondary telescopic rod is slidably installed inside the primary telescopic rod. The top of the main molding seat is provided with a threaded connecting seat, which is threadedly connected to the bottom of a fixed connecting seat. An inner connecting seat is threadedly connected to the inner side of the threaded connecting seat, and a guide rod is threadedly connected to the middle of the inner connecting seat. A telescopic spring is sleeved on the outer side of the guide rod, and the top and bottom ends of the telescopic spring abut against the inner connecting seat and the secondary telescopic rod, respectively. Multiple evenly distributed threaded grooves are opened on the top periphery of the main molding seat, and the periphery between the threaded connecting seat and the fixed connecting seat is also fixed by multiple bolts.

[0021] Through the above technical solution, the molding and pressing mechanism is mainly used for the pressing and molding of pouring cups. The main molding seat, in conjunction with the mold body, can quickly press the special sand filled in the molding groove into shape. In specific operation, during the feeding stage, the hydraulic drive mechanism drives the molding and pressing mechanism to move down as a whole until the bottom of the secondary telescopic rod contacts the support base plate. At this time, the bottom of the secondary telescopic rod moves into the ejector groove and fits against the inner wall of the ejector column. At this time, the telescopic spring is in the uncompressed normal state. After the pre-preparation is completed, the material can be fed normally. The feeding mechanism completes the filling and feeding of special sand. After the raw material is filled, the feeding mechanism is then manually smoothed. After the smoothing operation is completed, the hydraulic drive mechanism continues to drive the molding and pressing mechanism to move down. At this time, the secondary telescopic rod and the primary telescopic rod slowly retract to the inner wall of the main molding seat, and in the process, the telescopic spring is squeezed. When the main molding seat moves... Once the sand is placed in the forming groove, the main forming seat can press the special sand inside the groove to form a specially designed sprue cup shape. After pressing, the hydraulic drive mechanism will reset the forming pressing mechanism and completely separate the entire forming pressing mechanism from the sprue cup forming mold. At this time, when the ejector mechanism pushes the formed sprue cup out of the sprue cup forming mold, the sprue cup can be removed. Furthermore, by designing retractable primary and secondary telescopic rods at the bottom of the main forming seat, the secondary telescopic rod can be pre-extended into the ejector groove and fit against the inner wall of the ejector column. This prevents the special sand from leaking onto the support base plate during subsequent filling. During pressing, the integrity of the formed sprue cup can be guaranteed, without burrs or a large amount of waste. No manual shaping is required afterward, ensuring both normal processing progress and product quality.

[0022] Furthermore, the control mechanism includes a rotating bracket fixed to one side of the top of the processing platform, and a controller is rotatably connected to the top of the rotating bracket.

[0023] Through the above technical solution, the controller is mainly used for the integrated control of various mechanisms of the molding machine to ensure that the various mechanisms can operate in coordination, thereby ensuring the overall processing efficiency.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can quickly complete the pressing and molding of the pouring cup by designing a compact pouring cup forming mold, a material ejection mechanism and a molding pressing mechanism, which not only ensures the overall production and processing efficiency, but also ensures the processing quality of the product; (2) The present invention designs a telescopic first-level telescopic rod and a second-level telescopic rod at the bottom of the main molding seat, so that the second-level telescopic rod can be pre-extended into the material ejection groove and fit against the inner wall of the material ejection column. When filling later, it can prevent the special sand from leaking down to the support base plate. At this time, when pressing and molding, it can ensure the integrity of the pouring cup after molding, and will not produce burrs or a large amount of waste. There is no need for manual shaping later, which not only ensures the normal processing progress, but also ensures the product quality; (3) The present invention designs a two-level telescopic rod, which can play the role of preventing the special sand from leaking down, and also facilitates the feeding of special sand, avoiding the main molding seat from affecting the normal feeding operation.

Support columns 102 are fixedly connected to the top corners of the fixed base 101. A fixed top plate 103 is fixedly connected to the top of the multiple support columns 102. The fixed frame 1 serves as a support frame and mainly plays a supporting role. At the same time, the multiple support columns 102 can guide and limit the lifting and lowering of the lifting and lowering limit mechanism 7.

[0029] Regarding the pouring cup molding mold 3, please refer to... Figures 1-10 A processing platform 2 is fixedly connected to a fixed frame 1. A pouring cup forming mold 3 is fixedly installed in the middle of the processing platform 2. The pouring cup forming mold 3 includes a mold body 301 fixedly installed at the top center of the processing platform 2, a support base plate 302 fixedly installed at the bottom of the mold body 301, multiple evenly distributed limiting holes 303 on the periphery of the support base plate 302, a forming groove 304 at the top center of the mold body 301, and a through ejector groove 305 at the bottom of the forming groove 304. The pouring cup forming mold 3 is one of the key components of pouring cup forming, which can... The mold body 301 is fixedly installed on the processing platform 2 by bolts, which can ensure a stable connection and facilitate installation and disassembly. A separable support base plate 302 is fixedly installed at the bottom of the mold body 301. It is mainly used to cooperate with the molding and pressing mechanism 8 to support and limit the bottom end of the molding and pressing mechanism 8. The middle part of the mold body 301 is provided with a molding groove 304 and a material ejection groove 305. When the special sand is poured into the molding groove 304 and smoothed, the hydraulic drive mechanism 6 will drive the molding and pressing mechanism 8 to move downward, thereby cooperating with the mold body 301 to complete the rapid pressing and molding of the pouring cup.

[0030] Regarding material return mechanism 4, please refer to... Figures 1-10 The bottom of the fixed frame 1 is fixedly installed with a material ejection mechanism 4 that matches the casting cup forming mold 3. The material ejection mechanism 4 includes a support frame 401 fixed to the bottom of the fixed frame 1. A material ejection cylinder 402 is fixedly installed on the support frame 401. A support block 403 is fixedly connected to the top of the piston rod of the material ejection cylinder 402. Multiple evenly distributed material ejection rods 404 are fixedly connected to the top periphery of the support block 403. Material ejection columns 405 are fixedly connected to the top of the multiple material ejection rods 404. The material ejection mechanism 4 is mainly used for automatic material ejection after the casting cup is formed. When the casting cup is pressed and formed, the piston rod of the material ejection cylinder 402 will drive the multiple material ejection rods 404 and the material ejection columns 405 on its top to move upward synchronously through the support block 403. Thus, the material ejection columns 405 can be used to push the formed casting cup out of the forming groove 304, which makes it convenient for the staff to pick up the material. After the material ejection is completed, the material ejection cylinder 402 will automatically reset.

[0031] In this embodiment, the top ends of the multiple ejector rods 404 respectively pass through the corresponding limiting holes 303, and the ejector column 405 slides in the ejector groove 305, thereby facilitating the ejection of the molded sprue cup using the multiple ejector rods 404 and the ejector column 405 at their top ends.

[0032] Regarding feeding mechanism 5, please refer to... Figures 11-12A feeding mechanism 5 is fixedly installed at the rear end of the top of the processing platform 2. The feeding mechanism 5 includes a fixed bracket 501 fixed to the rear end of the top of the processing platform 2. Movable guide rails 502 are fixedly connected to both sides of the top of the fixed bracket 501. Movable slide blocks 503 are slidably connected to both movable guide rails 502. A connecting plate 504 is fixedly connected to the front end between the two movable slide blocks 503. Two fixed columns 505 are fixedly connected to the top of both movable slide blocks 503. A feeding tray 506 is fixedly connected to the top of the multiple fixed columns 505. A semi-circular slot 507 is opened at the front end of the feeding tray 506. A mounting base 508 is also fixedly connected to the top of the fixed bracket 501. A drive cylinder 509 is fixedly installed at the rear end of the mounting base 508. The front end of the piston rod of the drive cylinder 509 is connected to the connecting plate 504. The fixed connection and feeding mechanism 5 are used for auxiliary feeding of special sand. During the processing of the pouring cup, the hydraulic drive mechanism 6 first drives the molding and pressing mechanism 8 to move into the pouring cup molding mold 3 to complete the pre-preparation. Then, the piston rod of the drive cylinder 509 will start to extend forward, and then the connecting plate 504 will drive the entire feeding plate 506 to move towards the mold body 301 until it moves to the designated feeding position. Then, the special sand as raw material can be poured onto the feeding plate 506 by manual labor, special conveying mechanism or robot. At this time, the special sand will automatically pour along the inclined surface of the feeding plate 506 and finally fill the molding groove 304. When the feeding work is completed, the feeding mechanism 5 will quickly reset. At this time, the operator can smooth the special sand in the mold body 301.

[0033] Regarding hydraulic drive mechanism 6, refer to... Figures 1-6 A hydraulic drive mechanism 6 is installed at the top center of the fixed frame 1. The hydraulic drive mechanism 6 includes a hydraulic cylinder 601 fixed at the top center of the fixed frame 1. A fixed connecting seat 602 is fixedly connected to the bottom end of the piston rod of the hydraulic cylinder 601. Multiple evenly distributed mounting holes 603 are opened on the top periphery of the fixed connecting seat 602. As the main power unit in the pressing and molding process of the pouring cup, the hydraulic drive mechanism 6 moves downward when working. In turn, the piston rod of the hydraulic cylinder 601 moves downward, which can drive the lifting limit mechanism 7 and the molding pressing mechanism 8 to move downward synchronously through the fixed connecting seat 602. Then, the molding pressing mechanism 8 works with the pouring cup molding mold 3 to complete the pressing and molding of the pouring cup.

[0034] Regarding the lifting limit mechanism 7, please refer to... Figures 1-6A lifting limit mechanism 7 is also slidably installed on the fixed frame 1, and the movable end of the hydraulic drive mechanism 6 is fixedly connected to the lifting limit mechanism 7. The lifting limit mechanism 7 includes a lifting slide 701 slidably installed on the fixed frame 1. A connecting column 702 is fixedly connected to the bottom center of the lifting slide 701. An installation groove 703 is provided between the lifting slide 701 and the connecting column 702, and the fixed connecting seat 602 is fixed in the installation groove 703 by screws. The lifting limit mechanism 7 is mainly used for auxiliary limiting and precise guidance during the lifting process of the molding pressing mechanism 8. Since the sliding limit of the lifting slide 701 is located between multiple support columns 102, the processing accuracy of the molding pressing mechanism 8 during the working process can be guaranteed, and its position or angle deviation can be prevented, thereby ensuring the overall processing quality of the pouring cup.

[0035] Regarding molding and pressing mechanism 8, please refer to... Figures 1-16The bottom end of the hydraulic drive mechanism 6 is fixedly equipped with a molding and pressing mechanism 8 that matches the casting cup mold 3, used for pressing and molding the casting cup. The molding and pressing mechanism 8 includes a main molding seat 801, a primary telescopic rod 802 slidably installed inside the main molding seat 801, a secondary telescopic rod 803 slidably installed inside the primary telescopic rod 802, a threaded connecting seat 804 at the top of the main molding seat 801, the threaded connecting seat 804 being threadedly connected to the bottom of the fixed connecting seat 602, an inner connecting seat 805 being threadedly connected to the inner side of the threaded connecting seat 804, and a guide being threadedly connected to the middle of the inner connecting seat 805. A telescopic spring 807 is sleeved on the outer side of the guide rod 806. The top and bottom ends of the telescopic spring 807 abut against the inner connecting seat 805 and the secondary telescopic rod 803, respectively. The top circumference of the main forming seat 801 is provided with multiple evenly distributed threaded grooves 808, and the circumference between the threaded connecting seat 804 and the fixed connecting seat 602 is also fixed by multiple bolts. The forming and pressing mechanism 8 is mainly used for pressing and forming the pouring cup. The main forming seat 801, in conjunction with the mold body 301, can quickly press and form the special sand filled in the forming groove 304. In specific operation, during the feeding stage, it is driven by hydraulic pressure. The driving mechanism 6 drives the molding and pressing mechanism 8 to move downwards until the bottom of the secondary telescopic rod 803 contacts the support base plate 302. At this time, the bottom of the secondary telescopic rod 803 moves into the discharge groove 305 and fits against the inner wall of the discharge column 405. At this time, the telescopic spring 807 is in the uncompressed normal state. After the pre-preparation is completed, the material can be fed normally. The feeding mechanism 5 completes the filling and feeding of special sand. After the raw material is filled, the feeding mechanism 5 is then quickly smoothed by hand. After the smoothing operation is completed, the hydraulic drive mechanism 6 continues to drive the molding and pressing mechanism 8 to move downwards. At this time, the secondary telescopic rod... 803 and the first-stage telescopic rod 802 slowly retract to the inner wall of the main molding seat 801, and in the process, they squeeze the telescopic spring 807. When the main molding seat 801 moves into the molding groove 304, the main molding seat 801 can cooperate with the molding groove 304 to press the special sand inside it into shape, thereby forming a special pouring cup shape. After pressing, the hydraulic drive mechanism 6 will drive the molding pressing mechanism 8 to reset, and make the entire molding pressing mechanism 8 completely separate from the pouring cup molding mold 3. At this time, when the ejection mechanism 4 pushes the molded pouring cup out of the pouring cup molding mold 3, the pouring cup can be taken out.

[0036] Furthermore, in this embodiment, by designing retractable primary telescopic rod 802 and secondary telescopic rod 803 at the bottom of the main forming seat 801, the secondary telescopic rod 803 can be pre-extended into the ejector groove 305 and fit against the inner wall of the ejector column 405. When filling later, it can prevent special sand from leaking onto the support base plate 302. At this time, during the pressing process, the integrity of the sprue cup after molding can be guaranteed, and no burrs or a large amount of waste will be generated. No manual shaping is required afterward, which not only ensures the normal processing progress but also guarantees product quality.

[0037] Furthermore, in this embodiment, by designing a two-stage structure, the first-stage telescopic rod 802 and the second-stage telescopic rod 803, on the one hand, it can prevent the special sand from leaking down, and on the other hand, it can facilitate the feeding of special sand, so as to avoid the main forming seat 801 affecting the normal feeding operation.

[0038] Regarding control mechanism 9, refer to... Figures 1-5 A control mechanism 9 for controlling the molding machine is installed on one side of the top of the processing platform 2. The control mechanism 9 includes a rotating bracket 901 fixed to one side of the top of the processing platform 2. A controller 902 is rotatably connected to the top of the rotating bracket 901. The controller 902 is mainly used for the integrated control of various mechanisms of the molding machine to ensure that the various mechanisms can operate in coordination, thereby ensuring the overall processing efficiency.

[0039] The working principle of this embodiment is as follows: When feeding, the hydraulic drive mechanism 6 drives the forming and pressing mechanism 8 to move down as a whole until the bottom of the secondary telescopic rod 803 contacts the support base plate 302. At this time, the bottom of the secondary telescopic rod 803 moves into the unloading groove 305 and fits against the inner wall of the unloading column 405. After the pre-preparation is completed, the material can be fed normally. The feeding mechanism 5 will fill the special sand. After the material is filled, the feeding mechanism 5 will be quickly smoothed by the operator. After the smoothing operation is completed, the hydraulic drive mechanism 6 will continue to drive the molding and pressing mechanism 8 to move down. At this time, the secondary telescopic rod 803 and the primary telescopic rod 802 will slowly retract to the inner wall of the main molding seat 801 and squeeze the telescopic spring 807 in the process. When the main molding seat 801 moves into the molding groove 304, the main molding seat 801 can cooperate with the molding groove 304 to press the special sand inside it into shape, thereby forming a special pouring cup shape. After pressing and molding, the hydraulic drive mechanism 6 will drive the molding pressing mechanism 8 to reset and move the entire molding pressing mechanism 8 above the pouring cup molding mold 3. At this time, the piston rod of the ejector cylinder 402 will drive the multiple ejector rods 404 and ejector columns 405 at its top to move upward synchronously through the support block 403. This allows the ejector columns 405 to push the molded sprue cup out of the molding groove 304, making it easier for workers to remove the material. After the ejection is completed, the ejector cylinder 402 will automatically reset.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
