Description

Technical Field

[0001] This invention relates to the field of chip manufacturing technology, and more specifically, to a chip manufacturing system. Background Technology

[0002] The existing traditional core-making unit layout mostly involves placing the sand mixer above the core-making machine, with the sand outlet connecting to the transition sand storage hopper of the core-making machine. Therefore, a steel structure platform is required above the core-making machine to house the sand mixer system, including the sand storage hopper, which places high demands on the overall workshop height. Furthermore, if one sand mixer supplies multiple core-making machines, the steel structure platform must extend to each core-making machine. The entire core-making unit has a very large and complex structure, with a very inflexible layout, which is detrimental to production operation and maintenance. Summary of the Invention

[0003] The objectives of this invention include, for example, providing a core-making system that uses a split-type device, has a simple structure, is easy to maintain, and can reduce the height requirements of the entire device, making the layout more flexible.

Then, an automatic tilting device located on one side of the core-making device lifts the core sand to the core sand receiving hopper for dumping, completing the material transfer between the sand-mixing device and the core-making device. In actual sand-mixing and core-making, the sand-mixing device first performs the sand-mixing action, and the resulting core sand is discharged from the sand-mixing outlet. The movable sealing cylinder is connected to the sand-mixing outlet, seals the core sand inside, and transports it towards the core-making device. The automatic tilting device lifts the movable sealing cylinder to the core sand receiving hopper and dumps the core sand from the movable sealing cylinder into the core sand receiving hopper. Finally, the core-making action is completed by the core-making device. Compared to existing technologies, the core-making system provided by this invention does not require an integrated stacked structure, thus reducing the height requirements of the entire core-making unit. The height can be lower, and the installation height requirements of the factory are also lower, making it more flexible. At the same time, the use of an independent mobile sealed cylinder for core sand transportation can ensure a clean working environment on site and reduce VOC emissions. Furthermore, the split structure is easy to maintain. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0046] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0047] As disclosed in the background section, such as Figure 1 As shown, existing sand mixers are all configured above the core-making machine, with the sand outlet connected to the transition storage hopper of the core-making machine. Therefore, a steel structure platform is required above the core-making machine to house the sand mixer system, including the storage hopper above the mixer, which places high demands on the height of the entire workshop. Furthermore, existing sand mixers typically need to place the mixed core sand into the transition storage hopper of the core-making machine. Given the high requirements of the inorganic binder process, the mixed core sand needs to be isolated from air to prevent premature dehydration and curing. Therefore, additional humidification and sealing mechanisms are required for the transition storage hopper, undoubtedly making its structure more complex.

[0048] To address the aforementioned problems, this invention provides a novel core-making system that reduces installation height requirements, provides sealing conditions, and facilitates maintenance. It should be noted that, unless otherwise specified, features in the embodiments of this invention can be combined with each other.

[0049] First Embodiment

[0050] Please refer to Figure 2 and Figure 3 This embodiment provides a core-making system 100, which adopts a split structure and does not require an integrated stacked structure. Therefore, it can reduce the arrangement requirements of the entire core-making unit in the height direction, and the height can be lower, which also reduces the requirements for the installation height of the factory building and makes it more flexible. At the same time, the core sand is transported by an independent mobile sealing cylinder 150 to achieve sealed transport, which can ensure a clean working environment on site. The split structure is also easy to maintain.

[0051] The core-making system 100 provided in this embodiment includes a sand mixing device 110, a core-making device 130, a movable sealing cylinder 150, and an automatic tilting device 170. The sand mixing device 110 is used to mix sand, and the bottom of the sand mixing device 110 has a sand mixing outlet for discharging the mixed core sand. The core-making device 130 and the sand mixing device 110 are separately arranged on the same mounting surface, and the top of the core-making device 130 has a core sand receiving hopper 131. The movable sealing cylinder 150 is movably arranged between the sand mixing device 110 and the core-making device 130, and is used to receive core sand and convey it toward the core-making device 130. The automatic tilting device 170 is arranged on one side of the core-making device 130, and is used to lift the movable sealing cylinder 150 to the core sand receiving hopper 131 and tilt the core sand in the movable sealing cylinder 150 into the core sand receiving hopper 131.

[0052] In this embodiment, the sand mixing principle of the sand mixing device 110 and the core making principle of the core making device 130 are the same as those of conventional sand mixing and core making equipment, and are not specifically limited here. In actual sand mixing and core making, the sand mixing device 110 first performs the sand mixing action, and the core sand formed after mixing is discharged from the sand mixing outlet. The movable sealing cylinder 150 is connected to the sand mixing outlet, and the core sand is sealed and loaded into it and then conveyed toward the core making device 130. The automatic tilting device 170 lifts the movable sealing cylinder 150 to the core sand receiving hopper 131 and tilts the core sand in the movable sealing cylinder 150 into the core sand receiving hopper 131. Finally, the core making action is completed by the core making device 130. Compared to the conventional integrated sand mixing and core making structure, in this embodiment, the sand mixing device 110 and the core making device 130 are set separately on the same installation surface. Since there is no need to use an integrated stacked structure, the arrangement requirements of the entire core making unit in the height direction can be reduced, the height can be lower, the installation height requirements of the plant are also lower, and it is more flexible. At the same time, the use of an independent mobile sealing cylinder 150 for core sand transportation can ensure a clean working environment on site, and the split structure is also easy to maintain.

[0053] Furthermore, the core-making system 100 also includes a mobile carrier 190, which is positioned between the sand mixing device 110 and the core-making device 130. A mobile sealing cylinder 150 is placed on the mobile carrier 190, which drives the mobile sealing cylinder 150 to reciprocate between the sand mixing device 110 and the core-making device 130. Specifically, the mobile carrier 190 can be an AGV (Automated Guided Vehicle), capable of reciprocating between the automatic lifting device and the sand mixing device 110, thereby driving the mobile sealing cylinder 150 to transport core sand and return between the automatic lifting device and the sand mixing device 110. After the mobile sealing cylinder 150 has finished emptying the core sand, it can be returned along the original path by the automatic lifting device, and the empty mobile sealing cylinder 150 is placed on the AGV, which then transports it again to the sand mixing outlet of the sand mixing device 110 for the next round of core sand transport.

[0054] Of course, in other preferred embodiments of the present invention, the mobile sealing cylinder 150 can also be conveyed by means of a conveyor belt or the like. For example, a reciprocating conveyor belt can be set between the automatic lifting device and the sand mixing device 110 to reciprocate the mobile sealing cylinder 150.

[0055] The automatic tilting device 170 includes a lifting frame 171, a lifting drive mechanism 173, and a bearing gripping mechanism 175. The lifting frame 171 is located on one side of the core-making device 130 and extends upward. The lifting drive mechanism 173 is located on the lifting frame 171. The bearing gripping mechanism 175 is connected to the lifting drive mechanism 173. The bearing gripping mechanism 175 is used to grip and carry the movable sealing cylinder 150. The lifting drive mechanism 173 is used to drive the bearing gripping mechanism 175 to move closer to or away from the core sand receiving hopper 131. Specifically, the lifting frame 171 is fixedly installed next to the core-making device 130, and its height is not lower than that of the core-making device 130, which can provide the function of mechanism installation. The lifting drive mechanism 173 is installed on the lifting frame 171 to realize the power drive of the bearing gripping mechanism 175, so that the bearing gripping mechanism 175 can reciprocate between the bottom and top of the lifting frame 171. When the bearing gripping mechanism 175 moves to the top of the lifting frame 171, the lifting drive mechanism 173 can also pour the core sand in the movable sealing cylinder 150 into the core sand receiving hopper 131.

[0056] It should be noted that in this embodiment, the bearing gripping mechanism 175 is used to grip and fix the movable sealing cylinder 150. It can be a gripper structure or a bearing plate structure. There is no specific limitation on this. Its gripping or releasing of the movable sealing cylinder 150 can be controlled by a controller. The controller is also connected to the lifting drive mechanism 173 and can control its operation.

[0057] See also Figures 4 to 7The lifting drive mechanism 173 includes a lifting assembly 1731, a lifting platform 1733, and a linkage drive assembly 1735. The lifting assembly 1731 is mounted on the lifting frame 171. The lifting platform 1733 is connected to the lifting assembly 1731 and is used to move up and down along the lifting frame 171 under the drive of the lifting assembly 1731. The linkage drive assembly 1735 is mounted on the lifting platform 1733. The bearing gripping mechanism 175 is connected to the linkage drive assembly 1735. The linkage drive assembly 1735 is used to drive the bearing gripping mechanism 175 to move between the lifting platform 1733 and the core sand receiving hopper 131 when the lifting platform 1733 moves upward to its limit position. The movable sealing cylinder 150 is also used to engage with the core sand receiving hopper 131 and discharge material under the drive of the bearing gripping mechanism 175. Specifically, the lifting assembly 1731 can be a chain-type structure, including a motor and a lifting chain. The lifting chain is movably mounted on the lifting frame 171, and the lifting platform 1733 is fixedly connected to the lifting chain. The motor is located on the bottom side of the lifting frame 171 and connected to the lifting chain, thereby driving the lifting chain to move. Under the driving action of the lifting chain, the lifting platform 1733 can be lifted from the bottom end to the top end of the lifting frame 171, or transported from the top end to the bottom end. Of course, the specific type of the lifting assembly 1731 is not specifically limited here; it can also be a motor lead screw or other lifting structure. Any structure that can realize the lifting of the lifting platform 1733 is within the protection scope of this invention.

[0058] In this embodiment, the linkage drive assembly 1735 includes a linkage drive member and a transmission link. The linkage drive member is mounted on the lifting platform 1733. One end of the transmission link is connected to the linkage drive member, and the other end is connected to the bearing gripping mechanism 175. The linkage drive member can drive the transmission link to rotate. Specifically, during the lifting stage of the lifting platform 1733, the transmission link retracts onto the lifting platform 1733. At this time, the bearing gripping mechanism 175 is located on the lifting platform 1733. When the lifting platform 1733 moves to its top limit position, the linkage drive member can start to move under the action of the controller, driving the transmission link to rotate toward the core-making device 130. The bearing gripping mechanism 175 located at the end of the transmission link also moves toward the core-making device 130 until it engages with the core sand receiving hopper.

[0059] The movable sealing cylinder 150 includes a cylinder body 151, a sealing cover 153, and a cover opening and closing assembly 155. The top of the cylinder body 151 has a feed opening, and the sealing cover 153 is movably disposed at the feed opening. The bottom of the cylinder body 151 has a discharge opening, and the cover opening and closing assembly 155 is disposed at the discharge opening. The cylinder body 151 is used to move under the drive of the bearing gripping mechanism 175. The cover opening and closing assembly 155 is used to engage with the core sand receiving hopper and opens the discharge opening when engaged with the core sand receiving hopper. Specifically, the cylinder body 151 is a sealed storage container with structural openings at both the top and bottom, and its inner wall is coated with a non-stick resin coating to prevent sand adhesion during use and facilitate cleaning. Good sealing performance can extend the storage time of the core sand. The sealing cover 153 is an openable structure, opening during feeding and remaining sealed during conveying and discharging.

[0060] In this embodiment, the sand mixing device 110 includes a sand mixing frame 111, a sand storage hopper 113, a weighing hopper 115, and a sand mixing cylinder 117. The sand storage hopper 113 is located at the top of the sand mixing frame 111, the weighing hopper 115 is located below the sand storage hopper 113, and the sand mixing cylinder 117 is located below the weighing hopper 115 to achieve sand mixing. The bottom end of the sand mixing cylinder 117 is provided with a sand mixing outlet. Furthermore, an automatic opening device 118 is also provided on the sand mixing frame 111 next to the sand mixing cylinder 117. This automatic opening device 118 can open and close the sealing cover 153, thereby facilitating the direct discharge of core sand into the cylinder body 151. After the core sand quantity reaches the standard, the sealing cover 153 is closed to ensure the sealing of the cylinder body 151.

[0061] In this embodiment, to better achieve the sealing performance of the sealing cap 153, an elastic connector 1559 is also provided on the outside of the material cylinder body 151. The elastic connector 1559 can be a sealing spring. One end of the sealing spring is fixedly connected to the outside of the material cylinder body 151, and the other end is connected to the sealing cap 153. The sealing spring is in a stretched state, which can ensure that the sealing cap 153 is always pressed against the feed opening. When the mobile sealing cylinder 150 is transported to the sand mixing outlet by the AGV trolley, the automatic opening device 118 can pull the sealing cap 153 to open the feed opening. At this time, it is necessary to overcome the tensile force of the sealing spring. After the feeding is completed, the automatic opening device 118 releases the sealing cap 153, and the sealing cap 153 can be reset under the elastic force of the sealing spring and sealed against the feed opening.

[0062] In this embodiment, the cover plate opening and closing assembly 155 includes a first opening and closing cover 1551, a second opening and closing cover 1552, a first connecting rod 1553, a second connecting rod 1554, a first hinge gear 1555, and a second hinge gear 1556. Both the first hinge gear 1555 and the second hinge gear 1556 are hinged to the lower part of the barrel body 151, and the first hinge gear 1555 and the second hinge gear 1556 mesh with each other. One end of the first connecting rod 1553 is connected to the first hinge gear 1555, and the other end of the first connecting rod 1553 extends downwards at an angle away from the second hinge gear 1556. The middle part of the first connecting rod 1553 is connected to... The first opening and closing cover 1551 is connected; one end of the second connecting rod 1554 is connected to the second hinge gear 1556, and the other end of the second connecting rod 1554 extends downward at an angle away from the first hinge gear 1555, and the middle part of the second connecting rod 1554 is connected to the second opening and closing cover 1552; a support cover plate 133 is provided around the core sand receiving hopper, and the first connecting rod 1553 and the second connecting rod 1554 are used to open under the support of the support cover plate 133. The first opening and closing cover 1551 and the second opening and closing cover 1552 are movably covered on the discharge opening and are used to open or close the discharge opening under the drive of the first connecting rod 1553 and the second connecting rod 1554.

[0063] In this embodiment, there are two first connecting rods 1553 and two second connecting rods 1554. The two first connecting rods 1553 are respectively arranged on the front and rear sides of the material cylinder body 151, and the two second connecting rods 1554 are respectively arranged on the front and rear sides of the material cylinder body 151. The first connecting rods 1553 and the second connecting rods 1554 are arranged symmetrically from left to right. When the bottom ends of the first connecting rods 1553 and the second connecting rods 1554 are subjected to a holding pressure, the first connecting rods 1553 and the second connecting rods 1554 can open at the bottom ends, and the first opening and closing cover 1551 and the second opening and closing cover 1552 will move away from each other under the action of the first connecting rods 1553 and the second connecting rods 1554, thereby opening the discharge opening.

[0064] Furthermore, a first roller 1557 is provided at the end of the first connecting rod 1553 away from the first hinge gear 1555, and a second roller 1558 is provided at the end of the second connecting rod 1554 away from the second hinge gear 1556. Limiting inclined blocks are provided on the abutment cover plates 133 on both sides of the core sand receiving hopper to abut the first roller 1557 and the second roller 1558, respectively. Specifically, by providing limiting inclined blocks, an initial guiding function can be achieved, facilitating better force application and opening of the first connecting rod 1553 and the second connecting rod 1554, and preventing jamming.

[0065] In actual operation, the AGV trolley first transports the mobile sealing cylinder 150 to the sand mixing outlet of the core-making device 130. The sealing cover 153 of the cylinder body 151 is opened by the automatic opening device 118 to store sand. After the sand is stored, the sealing cover 153 is closed. Then, the AGV trolley transports the mobile sealing cylinder 150 filled with core sand to the bottom of the lifting frame 171. At this time, the bearing gripping mechanism 175 and the cylinder body 151 complete the gripping and fixing action. Under the action of the lifting component 1731, the lifting platform 1733 and the bearing gripping mechanism 175 move upward together. After being lifted to the top position, the linkage drive assembly 1735 moves the bearing gripping mechanism 175 toward the core sand receiving hopper 131. At this time, the movable sealing cylinder 150 descends from the core sand receiving hopper 131 under the drive of the bearing gripping mechanism 175. When the first connecting rod 1553 and the second connecting rod 1554 contact the abutment cover plate 133, the first connecting rod 1553 and the second connecting rod 1554 are forced to move upward and open with each other, thereby driving the first opening and closing cover 1551 and the second opening and closing cover 1552 to open the discharge opening, and the core sand falls from the discharge opening into the core sand receiving hopper 131. After the sand is fed, the movable sealing cylinder 150 is detached from the core sand receiving hopper 131. The first connecting rod 1553 and the second connecting rod 1554 move closer to each other under the action of gravity, and close the first opening and closing cover 1551 and the second opening and closing cover 1552, and then return along the original path to complete the entire cycle.

[0066] In summary, the core-making system 100 provided in this embodiment separates the core-making device 130 and the sand-mixing device 110 and sets them on the same mounting surface. A movable sealing cylinder 150 is used to seal and load the mixed core sand towards the core-making device 130. Then, an automatic tilting device 170, located on one side of the core-making device 130, lifts the core sand to the core sand receiving hopper 131 for dumping, thus completing the material transfer between the sand-mixing device 110 and the core-making device 130. In actual sand-mixing and core-making, the sand-mixing device 110 first performs the sand-mixing action, and the resulting core sand is discharged from the sand-mixing outlet. The movable sealing cylinder 150 is connected to the sand-mixing outlet, seals the core sand inside, and then transports it towards the core-making device 130. The automatic tilting device 170 lifts the moved movable sealing cylinder 150 to the core sand receiving hopper 131 and dumps the core sand from the movable sealing cylinder 150 into the core sand receiving hopper 131. Finally, the core-making action is completed by the core-making device 130. Compared to existing technologies, the core-making system 100 provided in this embodiment does not require an integrated stacked structure, thus reducing the height requirements of the entire core-making unit. The height can be lower, and the installation height requirements of the plant are also lower, making it more flexible. At the same time, the core sand is transported using an independent mobile sealed cylinder 150, and the mixed core sand is stored in a relatively sealed cylinder, which can greatly extend the usable time of the core sand, ensure the quality of the core-making process at the end, and ensure a clean working environment on site. Furthermore, the independent placement of the sand mixing unit combined with the sealed storage cylinder ensures a clean working environment and convenient maintenance on site.

[0067] Second Embodiment

[0068] See also Figures 8 to 12 The core-making system 100 provided in this embodiment has the same basic structure, principle and technical effect as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0069] In this embodiment, the lifting drive mechanism 173 includes a lifting drive component 1737, a first tilting rail 1738, and a second tilting rail 1739. Both the first tilting rail 1738 and the second tilting rail 1739 are mounted on the lifting frame 171. The top end of the first tilting rail 1738 bends towards the core sand receiving hopper to form a first bend, and the top end of the second tilting rail 1739 bends towards the core sand receiving hopper to form a second bend. The first bend is located above the second bend, supporting the gripping mechanism 17. 5 has a transmission handle 1751, which is movably connected to the first tilting rail 1738 and the second tilting rail 1739. The lifting drive component 1737 is located at the bottom end of the first tilting rail 1738 and the second tilting rail 1739 and is used to drive the bearing gripping mechanism 175 to move along the first tilting rail 1738 and the second tilting rail 1739. When the bearing gripping mechanism 175 moves to the first bend and the second bend, the movable sealing cylinder is inverted and engaged with the core sand receiving hopper 131.

[0070] In this embodiment, the lifting drive 1737 can be a winch. The chain or transmission belt of the winch is arranged along the first tilting track 1738 or the second tilting track 1739, thereby driving the bearing gripping mechanism 175 to move up and down reciprocally along the first tilting track 1738 and the second tilting track 1739.

[0071] It should be noted that in this embodiment, the bearing gripping mechanism 175 can be a gripping cylinder structure, and it grips and fixes itself on the movable sealing cylinder 150 to achieve the fixation of the movable sealing cylinder 150. The transmission handle 1751 has two fulcrums, which are respectively set along the first tilting track 1738 and the second tilting track 1739. The front sections of the first tilting track 1738 and the second tilting track 1739 are both placed vertically, and the first tilting track 1738 is located on the side of the second tilting track 1739 away from the core-making device 130. At this time, the transmission handle 1751 is placed horizontally on the first tilting track 1738 and the second tilting track 1739 to ensure that the bearing gripping mechanism 175 and the movable sealing cylinder 150 are also kept horizontal. When the transmission handle 1751 moves upward to the first bend and the second bend, since the first bend is higher than the second bend, the transmission handle 1751 can be flipped from the horizontal state, thereby driving the bearing gripping mechanism 175 and the movable sealing cylinder 150 to flip, so that the feed end of the movable sealing cylinder 150 faces the core sand receiving hopper, realizing the tilting of the core sand.

[0072] The movable sealing cylinder 150 includes a cylinder body 151 and a cover plate opening and closing assembly 155. The top of the cylinder body 151 is provided with an inlet and outlet. The cover plate opening and closing assembly 155 is provided to seal the inlet and outlet. The cylinder body 151 is used to move under the drive of the bearing gripping mechanism 175. The cover plate opening and closing assembly 155 is used to engage with the core sand receiving hopper and open the inlet and outlet when engaging with the core sand receiving hopper.

[0073] In this embodiment, the cover opening and closing assembly 155 includes a first opening and closing cover 1551, a second opening and closing cover 1552, a first connecting rod 1553, a second connecting rod 1554, a first hinge gear 1555, a second hinge gear 1556, and an elastic connector 1559. The first hinge gear 1555 and the second hinge gear 1556 are both hinged to the lower part of the barrel body 151, and the first hinge gear 1555 and the second hinge gear 1556 mesh with each other. One end of the first connecting rod 1553 is connected to the first hinge gear 1555, and the other end of the first connecting rod 1553 extends downwards at an angle away from the second hinge gear 1556. The middle part of the first connecting rod 1553 is connected to the first opening and closing cover 1551. One end of the second connecting rod 1554 is connected to the second hinge gear 1556. The gear 1556 is connected, and the other end of the second connecting rod 1554 extends downward at an angle away from the first hinged gear 1555, and the middle part of the second connecting rod 1554 is connected to the second opening and closing cover 1552; a limit block 135 is provided on one side of the core sand receiving hopper, and at least one of the first connecting rod 1553 and the second connecting rod 1554 is used to open under the resistance of the limit block 135. The first opening and closing cover 1551 and the second opening and closing cover 1552 are movably covered on the inlet and outlet, and are used to open or close the inlet and outlet under the drive of the first connecting rod 1553 and the second connecting rod 1554; the two ends of the elastic connecting member 1559 are respectively connected to the middle parts of the first connecting rod 1553 and the second connecting rod 1554, so that the first connecting rod 1553 and the second connecting rod 1554 approach each other.

[0074] It should be noted that the basic structure of the cover opening and closing assembly 155 in this embodiment can refer to the first embodiment. The difference from the first embodiment is the addition of an elastic connector 1559 to ensure that the first connecting rod 1553 and the second connecting rod 1554 can be in a close-to-each-other state when no external force is applied, so as to facilitate the closing of the inlet and outlet ports by the first opening and closing cover 1551 and the second opening and closing cover 1552. Specifically, the elastic connector 1559 can be a tension spring, which uses tension force to pull the first connecting rod 1553 and the second connecting rod 1554 closer to each other.

[0075] In this embodiment, the sand mixing frame 111 of the sand mixing device 110 is also provided with a top opening mechanism 119. The top opening mechanism 119 plays a similar role to the automatic opening device 118 in the first embodiment. It can abut against the first connecting rod 1553 or the second connecting rod 1554 to open the first opening cover 1551 and the second opening cover 1552, so as to facilitate sand storage.

[0076] In actual operation, the AGV trolley first transports the mobile sealing cylinder 150 to the sand mixing outlet of the core-making device 130. The cover opening and closing assembly 155 of the cylinder body 151 is opened by the top opening mechanism 119 to store sand. After the sand is stored, the first opening and closing cover 1551 and the second opening and closing cover 1552 are closed by the elastic connector 1559. Then, the AGV trolley transports the mobile sealing cylinder 150 filled with core sand to the bottom of the lifting frame 171. At this time, the bearing gripping mechanism 175 and the cylinder body 151 complete the gripping and fixing action, and the lifting drive component... Under the action of 1737, the bearing gripping mechanism 175 drives the movable sealing cylinder 150 to move upward together. After moving to the top, under the action of the first and second bends, the bearing gripping mechanism 175 and the movable sealing cylinder 150 flip together, causing the first connecting rod 1553 or the second connecting rod 1554 to contact the limiting block 135. Under the resistance of the limiting block 135, the first connecting rod 1553 and the second connecting rod 1554 open up to each other and open the inlet and outlet ports, allowing the core sand to enter the core sand receiving hopper 131 from the inlet and outlet ports, completing the sand feeding. After the sand feeding is completed, the movable sealing cylinder 150 returns along the original path, and the first connecting rod 1553 and the second connecting rod 1554 are closed by the tension force of the tension spring, completing the entire cycle.

[0077] The core-making system 100 provided in this embodiment of the invention separates the core-making device 130 and the sand mixing device 110 and sets them on the same mounting surface. The core sand that has been mixed is sealed and transported toward the core-making device 130 by a movable sealing cylinder 150. Then, the core sand is lifted to the core sand receiving hopper 131 by an automatic tilting device 170 set on one side of the core-making device 130 and tilted, thus completing the material transfer between the sand mixing device 110 and the core-making device 130. Compared to existing technologies, the core-making system 100 provided in this embodiment does not require an integrated stacked structure, thus reducing the height requirements of the entire core-making unit. The height can be lower, and the installation height requirements of the plant are also lower, making it more flexible. At the same time, the core sand is transported using an independent mobile sealed cylinder 150, and the mixed core sand is stored in a relatively sealed cylinder, which can greatly extend the usable time of the core sand, ensure the quality of the core-making process at the end, and ensure a clean working environment on site. Furthermore, the independent placement of the sand mixing unit combined with the sealed storage cylinder ensures a clean working environment and convenient maintenance on site.
