Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a die casting mold inclined core pulling locking leg stop structure. Background Technology

[0002] The core-pulling mechanism is a crucial component of die-casting molds. Its primary function is to extract or retract the movable core of the die-cast part according to a specified direction and stroke during the die-casting process, ensuring smooth demolding. A core-pulling mechanism typically consists of inclined guide pillars, side cores, sliders, guide grooves, limit blocks, screws, springs, nuts, and bolts. Among these, the inclined guide pillar is the key component. Its function is to force the slider to move at an angle during mold opening, thereby extracting or retracting the core. Inclined guide pillars come in two forms: internal and external. Their cross-sectional shape is often flat and round to prevent damage to the slider during core extraction.

[0003] When the mold adopts a parting mold cavity and a core-pulling device is arranged in the mold cavity, a locking module is required to lock the core-pulling device. After long-term use, the mold will experience certain wear, which can easily cause slight pushing force between the core-pulling block and the product, greatly affecting the product quality. At the same time, during production, the inclined guide post is locked by increasing pressure through electricity. If the power is interrupted during production, leakage can easily occur, which may lead to an accident. In view of this technical problem, this application proposes an inclined core-pulling locking and stop leg structure for die casting molds. Utility Model Content

[0023] 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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a die-casting mold with a slanted core-pulling and locking anti-reverse structure, including a moving mold 1 responsible for mold closing. A guide groove 2 is installed on the inner wall of the moving mold 1, through which a slanted guide post 11 can be pushed to a designated position to complete core pulling after injection molding. The slanted guide post 11 is slidably connected to the inner wall of the guide groove 2, responsible for completing the undercut structure of the molded part. A groove 18 is formed on the inner wall of the guide groove 2. Wedge blocks 17 are fixedly connected to both sides of the outer wall of the slanted guide post 11. The wedge blocks 17 on both sides of the slanted guide post 11 can lock the slanted guide post 11 into the groove 18 on the inner wall of the guide groove 2, thereby completing the core pulling. The inclined guide post 11 is locked in place. A gasket 16 is fixedly connected to the outer wall of the inclined guide post 11 to separate the gear 2 14 from the guide groove 2 and prevent the guide groove 2 from interfering with the operation of the gear 2 14. A steering component is provided on the outer wall of the gasket 16. The inclined guide post 11 and the wedge block 17 can rotate through the steering component. A connecting block 12 is fixedly connected to the end of the inclined guide post 11. A slider 8 is fixedly connected to one side of the outer wall of the connecting block 12. The slider 8 on the connecting block 12 can be moved by the movement of the core seat 6. An elastic component is provided on the other side of the connecting block 12 to further increase the pressure and avoid misalignment caused by mold wear.

[0025] Reference Figures 3-4The steering assembly includes a mounting bracket 10 rotatably connected to the outer wall of the inclined guide post 11. A motor 20 is mounted on one side of the mounting bracket 10 via a fixed bracket. A gear 13 is provided at the drive end of the motor 20. The inner wall of the gear 13 is fixedly connected to the inclined guide post 11. A gear 24 is rotatably connected to the other side of the mounting bracket 10. The gear 13 and the gear 24 are connected by a chain 15. The outer wall of the shim 16 is rotatably connected to the gear 13. When the inclined guide post 11 reaches the designated position, the motor 20 on the mounting bracket 10 will drive the gear 13 to rotate, thereby driving the gear 24 to rotate by the chain 15, which in turn drives the wedge block 17 on the inclined guide post 11 to rotate.

[0026] The elastic component includes multiple disc springs 19 slidably connected to the outer wall of the end of the inclined guide post 11. The outer wall of the multiple disc springs 19 is provided with a sealing cover 9, which is connected to the connecting block 12. One end of the multiple disc springs 19 abuts against the connecting block 12, and the other end abuts against the mounting bracket 10. The sealing cover 9 on the outer wall of the disc springs 19 is used to fix the disc springs 19 and prevent the disc springs 19 from being misaligned. The multiple disc springs 19 can exert a continuous force on the mounting bracket 10 through their own elasticity, thereby making the inclined guide post 11 more stable in the guide groove 2.

[0027] The inner wall of the moving mold 1 is equipped with a core seat 6, which is responsible for pushing the inclined guide post 11. The inner wall of the core seat 6 is provided with an I-shaped slide groove 7. The outer wall of the I-shaped slide groove 7 is connected to the slider 8. The movement of the core seat 6 drives the slider 8 in the I-shaped slide groove 7 to move, thereby driving the inclined guide post 11 into the mold. The outer wall of the groove 18 is connected to the wedge block 17. The groove 18 is used to fix the wedge block 17. The inner wall of the moving mold 1 is provided with a feed port 3. The die casting mold can be completed through the feed port 3. A fixed mold 4 is installed on one side of the moving mold 1, and a tail plate 5 is installed on the other side of the moving mold 1. The tail plate 5 will push the moving mold 1 to press against the fixed mold 4, thereby completing the mold closing.

[0028] Working principle: During die casting, the tail plate 5 pushes the moving mold 1 towards the fixed mold 4 to complete mold closing. The core seat 6 moves downward, and the sliding block 8 on the connecting block 12 moves through the I-shaped sliding groove 7 on the inner wall, thereby pushing the inclined guide post 11 to slide in the guide groove 2 to the designated position. After reaching the designated position, the motor 20 on the mounting bracket 10 drives the gear 13 to rotate, which in turn drives the chain 15 to drive the gear 14 to rotate, further driving the wedge block 17 on the inclined guide post 11 to rotate, thereby locking the inclined guide post 11 on the guide groove 2, preventing the pressure during die casting from pushing the inclined guide post 11 out. Then, the feed port 3 injects the raw material. The mold is die-cast under pressure. Multiple disc springs 19 on the inclined guide post 11 abut one end against the connecting block 12 and the other end against the mounting bracket 10. The multiple disc springs 19 can exert a continuous force on the mounting bracket 10 through their own elasticity, so that the inclined guide post 11 is more stable in the guide groove 2. After the injection molding is completed, the motor 20 will continue to drive the gear 13 to rotate, thereby releasing the guide groove 2 from the inclined guide post 11. Then the core seat 6 moves upward to pull out the inclined guide post 11, thereby completing the core pulling. Then the tail plate 5 will move backward to drive the moving mold 1 to move, thereby opening the die-casting mold and taking out the die-cast item.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
