Description

Technical Field

[0001] This utility model relates to a stamping die, specifically a combined metal part stamping die, belonging to the field of stamping die technology. Background Technology

[0002] Stamping dies are key process equipment used in cold stamping in manufacturing. They apply pressure to materials using a press, causing separation or plastic deformation to obtain the desired parts. Based on their function, they can be classified into blanking dies, bending dies, drawing dies, forming dies, and riveting dies. These dies are widely used in various industries such as automotive, home appliances, electronics, and construction, providing essential tools for manufacturing various parts.

[0003] Most existing metal stamping dies adopt a one-piece structure design. While this design ensures the integrity and stability of the die to a certain extent, it also brings the problem of inconvenience in replacing the template and inserts. In actual use, once a part of the die is worn or damaged, because the die is a one-piece structure, it is often necessary to disassemble and replace the entire die. This not only increases the difficulty and cost of maintenance, but also seriously affects production efficiency and product quality. In addition, replacing the template and inserts of a one-piece die requires more time and manpower, which also causes inconvenience to operators. Therefore, a modular metal stamping die is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a combined metal stamping die to solve the problems mentioned in the background art, such as the inconvenience of replacing templates and inserts in existing metal stamping dies, which increases the difficulty and cost of maintenance and affects production efficiency and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined metal stamping die, comprising a lower die assembly, wherein an upper die assembly is provided on the top of the lower die assembly, and the lower die assembly comprises a lower die base, a guide sleeve, a lower template, a limiting seat, a spring block, a connecting block, an insert, a guide rod, a limiting block and a spring;

[0006] The top of the lower mold base is symmetrically and fixedly connected with guide sleeves, and the top of the lower mold base is fixedly connected with a lower template. Limit seats are symmetrically and fixedly connected to both sides of the lower template. A spring block is slidably connected to the inner side wall of the limit seat. A connecting block is provided on the inner side wall of the lower template. An insert is fixedly connected to the top of the connecting block. A guide rod is slidably connected to the inner side wall of the connecting block. A limit block is fixedly connected to one end of the guide rod. A spring is sleeved on the outer side wall of the guide rod. When the connecting block is placed inside the lower template, the spring pushes the limit block to move, so that the limit block is inserted into the interior of the limit seat, thus fixing the connecting block inside the lower template and completing the fixing of the insert. When replacing the insert, push the spring block to make the limit block retract, and the connecting block can be removed.

[0007] Preferably, the upper mold assembly includes an upper mold base and an upper template;

[0008] The bottom of the upper mold base is evenly provided with several upper templates, which are sequentially inserted and arranged at the bottom of the upper mold base.

[0009] Preferably, the bottom of the upper mold base is symmetrically and fixedly connected with guide posts, which are disposed inside the guide sleeve.

[0010] Preferably, a positioning block is symmetrically fixedly connected to one side of the upper template, and positioning holes are symmetrically opened on one side of the upper template.

[0011] Preferably, the upper template has a threaded rod inside.

[0012] Preferably, the outer wall of the threaded rod is threaded with a fixing nut.

[0013] Preferably, the upper mold base is fixedly connected to the upper template by fixing bolts.

[0014] Preferably, the upper template is positioned on top of the lower template.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] 1. This utility model uses a spring to push the limiting block to move.

The operation is simple and convenient, and the efficiency of insert replacement is improved.

[0017] 2. This utility model uses several upper templates to form an overall template. When the template is worn or damaged, the damaged upper template can be disassembled and replaced separately without reprocessing the entire template, saving manpower and time, and reducing production difficulty and cost.

[0030] A guide sleeve 12 is symmetrically fixedly connected to the top of the lower mold base 11, and a lower template 13 is fixedly connected to the top of the lower mold base 11. Limit seats 14 are symmetrically fixedly connected to both sides of the lower template 13. A spring block 15 is slidably connected to the inner side wall of the limit seat 14. A connecting block 16 is provided on the inner side wall of the lower template 13. An insert 17 is fixedly connected to the top of the connecting block 16. A guide rod 18 is slidably connected to the inner side wall of the connecting block 16. A limit block 19 is fixedly connected to one end of the guide rod 18. A spring 110 is sleeved on the outer side wall of the guide rod 18. When the connecting block 16 is placed inside the lower template 13, the spring 110 pushes the limit block 19 to move, so that the limit block 19 is inserted into the interior of the limit seat 14, thus fixing the connecting block 16 inside the lower template 13 and completing the fixing of the insert 17. When replacing the insert 17, push the spring block 15 to make the limit block 19 retract, and the connecting block 16 can be removed. The operation is simple and convenient.

[0031] In this embodiment, specifically: the upper mold assembly 20 includes an upper mold base 21 and an upper template 23;

[0032] Several upper templates 23 are evenly arranged at the bottom of the upper mold base 21. The upper templates 23 are sequentially inserted and arranged at the bottom of the upper mold base 21. The multiple upper templates 23 are arranged in order. After the templates are worn or damaged, the damaged upper templates 23 can be removed individually.

[0033] In this embodiment, specifically: guide posts 22 are symmetrically fixedly connected to the bottom of the upper mold base 21. The guide posts 22 are disposed inside the guide sleeve 12. The guide posts 22 and the guide sleeve 12 cooperate to ensure that the mold can be accurately matched during the stamping process.

[0038] In this embodiment, specifically: the upper template 23 is set on top of the lower template 13. During stamping, the driving device pushes the upper template 23 downward, and the upper template 23 and the lower template 13 cooperate to complete the stamping work.

[0039] The working principle or structural principle is as follows: When assembling the mold, the connecting block 16 is placed inside the lower template 13. The spring 110 pushes the limiting block 19 to move, so that the limiting block 19 is inserted into the limiting seat 14, fixing the connecting block 16 inside the lower template 13 and completing the fixing of the insert 17. When replacing the insert 17, push the spring block 15 to make the limiting block 19 retract, and the connecting block 16 can be removed. The operation is simple and convenient, improving the replacement efficiency of the insert 17. Multiple upper templates 23 are arranged in sequence and inserted into the upper template 23 in sequence through the positioning holes 24 and positioning blocks 25. After the insertion is completed, the fixing nut 27 is fixed on the threaded rod 26, so that the multiple upper templates 23 form an integral template. Finally, the template is fixed to the upper mold base 21 by the fixing bolt 28. After the template is worn or damaged, the damaged upper template 23 can be disassembled and replaced individually without reprocessing the entire template, saving manpower and time, and reducing production difficulty and cost.
