Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to multi-station forming molds. Background Technology

[0002] Multi-station molding dies are core tools in industrial production used to shape materials. Through pre-set cavities and structures, they process raw materials (such as plastics, metals, and rubber) into products of specific shapes. Their function is to use pressure, temperature, and other conditions to cause physical or chemical changes in the raw materials within the mold, accurately replicating the contours and details of the mold cavity, ensuring the consistency and precision of product dimensions and shape.

[0003] A multi-station molding die for automotive parts, disclosed in patent publication number CN216682994U, includes an upper die and a lower die. Activating a first electric telescopic rod moves a connecting plate and the upper die downwards, causing the upper and lower dies to fit together for easy casting of automotive parts. After casting, activating the first electric telescopic rod moves the upper die upwards, causing a push plate, positioning rod, and connecting rod to move upwards. When the connecting rod abuts against the fixing rod, the upper die continues to move upwards, while the push plate moves downwards relative to the upper die, quickly demolding the die. The demolded die is located inside the lower die. A water pipe is connected to an external water source, allowing external water to enter a sleeve and a water collection tray, and then be sprayed out through several nozzles. The sprayed water cools the die inside the lower die on the right side, accelerating the cooling process.

[0004] The above-mentioned device uses two sets of push plates to demold the mold from both sides during demolding, which is difficult to remove and may cause product deformation or mold damage. In addition, the injection mold needs to be manually removed after cooling, which is quite troublesome. In order to address the above problems, a multi-station molding mold is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station forming mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-station forming mold includes a base, two sets of lower molds disposed on the top of the base, and an upper mold disposed on the top of the lower molds. A limiting groove is provided on the top of the base, and two sets of limiting plates are slidably connected in the limiting groove. A push plate is fixedly connected to the top of the two sets of limiting plates. A movable plate is provided in the lower mold, and an ejection component for moving the movable plate is provided in the limiting groove.

[0008] The ejection assembly includes a moving groove and a moving block. The moving groove is opened at the bottom of the inner wall of the limiting groove. The moving block is slidably connected in the moving groove. Two sets of rotating plates are rotatably connected on the moving block. The end of the rotating plate away from the moving block is rotatably connected between the two sets of limiting plates. A driving component for simultaneously driving the two sets of moving blocks to slide is installed on one side of the base.

[0009] The base is provided with a sliding component for moving the upper mold up and down, and the moving groove is provided with a limiting component for guiding the movement of the moving block.

[0010] In one alternative embodiment: the driving component includes a bidirectional screw, which is rotatably connected in two sets of movable slots. The movable block has threaded holes for threaded connection with the bidirectional screw. The two sets of threads on the bidirectional screw, corresponding to the movable block, have opposite directions of rotation. A motor for driving the bidirectional screw to rotate is installed on one side of the base.

[0011] In one alternative embodiment: the sliding assembly includes a lower pressure plate and guide rods. The lower pressure plate is fixedly connected to the top of two sets of upper molds. Several sets of guide rods are fixedly connected to the top of the base. A set of fixing plates is fixedly connected to the top of the several sets of guide rods. The lower pressure plate is slidably connected to the guide rods. Two sets of electro-hydraulic rods are installed on the fixing plate. The power output end of the electro-hydraulic rods is fixedly connected to the top of the lower pressure plate.

[0012] In one alternative: the limiting component includes guide grooves and guide blocks, two sets of guide grooves are respectively opened on both sides of the movable block, two sets of guide blocks are respectively fixedly connected to both sides of the inner wall of the movable groove, and the guide blocks are slidably connected in the guide groove.

[0013] In one alternative: the two sets of limiting plates on opposite sides slide against the inner wall of the limiting groove.

[0014] In one alternative: a groove is provided on one side of the lower mold for engaging with the push plate, and the limiting groove is connected to the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention comprises a base, a lower mold, a movable plate, a push plate, a limiting plate, and an ejection assembly. A driving component drives the movable block to slide within a movable groove, and a rotating plate drives the limiting plate to slide within a limiting groove. This causes the push plate to move to the bottom of the movable plate. After the movable block moves to one side of the inner wall of the movable groove, the rotating plate flips, causing the limiting plate and push plate to move upward and lift the movable plate, thereby achieving the effect of mold demolding. This avoids product deformation or mold damage and reduces the inconvenience of manually removing the product.

[0017] This invention, by setting a sliding component, allows the upper mold to move up and down, facilitating product molding and demolding. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4In this embodiment, the multi-station forming mold includes a base 11, two sets of lower molds 12 disposed on the top of the base 11, and an upper mold 28 disposed on the top of the lower molds 12. A limiting groove 20 is formed on the top of the base 11, and two sets of limiting plates 15 are slidably connected in the limiting groove 20. A push plate 14 is fixedly connected to the top of the two sets of limiting plates 15. A moving plate 13 is disposed in the lower mold 12, and an ejection component for moving the moving plate 13 is disposed in the limiting groove 20.

[0026] The ejection assembly includes a moving groove 19 and a moving block 17. The moving groove 19 is located at the bottom of the inner wall of the limiting groove 20. The moving block 17 is slidably connected to the moving groove 19. Two sets of rotating plates 16 are rotatably connected to the moving block 17. The end of the rotating plate 16 away from the moving block 17 is rotatably connected between the two sets of limiting plates 15. A driving component is installed on one side of the base 11 to simultaneously drive the two sets of moving blocks 17 to slide. The driving component drives the moving block 17 to slide in the moving groove 19 and drives the limiting plate 15 to slide in the limiting groove 20 through the rotating plate 16, so that the push plate 14 is inserted into the lower mold 12. After the moving block 17 moves to one side of the inner wall of the moving groove 19, the rotating plate 16 flips, so that the limiting plate 15 and the push plate 14 move upward to lift the moving plate 13, thereby achieving the effect of mold demolding, avoiding deformation of the product or damage to the mold, and reducing the trouble of manually removing the product.

[0027] The base 11 is provided with a sliding component for moving the upper mold 28 up and down, and the moving groove 19 is provided with a limiting component for guiding the movement of the moving block 17.

[0028] The driving component includes a bidirectional screw 22, which is rotatably connected to two sets of moving slots 19. The moving block 17 has a threaded hole for threaded connection with the bidirectional screw 22. The two sets of threads on the bidirectional screw 22 and the moving block 17 have opposite directions of rotation. A motor 23 for driving the bidirectional screw 22 to rotate is installed on one side of the base 11. When the motor 23 is started, it drives the bidirectional screw 22 to rotate. As the bidirectional screw 22 rotates, the moving block 17 slides in the moving slot 19, which facilitates driving the two sets of moving blocks 17 to move towards each other in the corresponding moving slots 19.

[0029] The sliding assembly includes a lower pressure plate 26 and guide rods 24. The lower pressure plate 26 is fixedly connected to the top of two sets of upper molds 28. Several sets of guide rods 24 are fixedly connected to the top of the base 11. A set of fixing plates 25 are fixedly connected to the top of the several sets of guide rods 24. The lower pressure plate 26 is slidably connected to the guide rods 24. Two sets of electro-hydraulic rods 27 are installed on the fixing plate 25. The power output end of the electro-hydraulic rods 27 is fixedly connected to the top of the lower pressure plate 26. When the electro-hydraulic rods 27 are activated and retracted, they drive the lower pressure plate 26 to slide on the guide rods 24, thereby driving the upper molds 28 to move upward and separate from the lower molds 12. The upper molds 28 can be moved up and down, which facilitates product molding and demolding.

[0030] The limiting component includes guide grooves 18 and guide blocks 21. Two sets of guide grooves 18 are respectively opened on both sides of the moving block 17. Two sets of guide blocks 21 are respectively fixedly connected to both sides of the inner wall of the moving groove 19. The guide blocks 21 are slidably connected in the guide grooves 18. The guide blocks 21 slide in the guide grooves 18, which can guide and limit the movement of the moving block 17 and prevent the moving block 17 from shaking.

[0031] The two sets of limiting plates 15 are slidably engaged with the inner wall of the limiting groove 20 on opposite sides, which facilitates limiting the movement of the limiting plates 15.

[0032] The lower mold 12 has a groove on one side for engaging the push plate 14. The limiting groove 20 is connected to the groove. By setting the groove, the push plate 14 can be easily engaged in the lower mold 12 and located at the bottom of the moving plate 13, making it easy to push the moving plate 13 upward.

[0033] The working principle of this utility model is as follows: During demolding, the electric hydraulic rod 27 starts and retracts, driving the lower pressure plate 26 to slide on the guide rod 24, thereby driving the upper mold 28 to move upward and separate from the lower mold 12. The motor 23 starts and drives the bidirectional screw 22 to rotate. As the bidirectional screw 22 rotates, the moving block 17 slides in the moving groove 19, causing the guide block 21 to slide in the guide groove 18. The rotating plate 16 drives the limiting plate 15 to slide in the limiting groove 20, thereby causing the push plate 14 to be inserted into the groove on one side of the lower mold 12. After the push plate 14 is fully inserted into the groove, the moving block 17 moves to one side of the inner wall of the moving groove 19. The rotating plate 16 flips, causing the limiting plate 15 and the push plate 14 to move upward and lift the moving plate 13, thereby achieving the effect of demolding and avoiding deformation or damage to the product and reducing the trouble of manually removing the product.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
