Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a hot stamping fixture for a plug cap. Background Technology

[0002] During stamping, the metal material is subjected to strong pressure within the die, generating a large amount of gas. If this gas is not released in time, it will affect product quality and processing efficiency. In existing die caps, the bottom and sidewalls are vertically aligned, leaving no gap when the punch enters, preventing gas from escaping. This results in a protrusion inside the die cap at the point of contact with the punch, further impacting product quality and processing efficiency. Utility Model Content

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.

[0019] like Figures 1-4As shown, a hot stamping tooling for a plug cap includes a guide sleeve 1 and a mold core 8. The ends of the guide sleeve 1 and the mold core 8 are fitted together. A guide hole 2 is provided in the guide sleeve 1, which is connected to the end of the guide sleeve 1 near the mold core 8. An ejector hole 9 and a forming cavity 10 are provided in the mold core 8, which are connected to each other. The ejector hole 9 is connected to the end of the mold core 8 near the guide sleeve 1, and the forming cavity 10 is connected to the end of the mold core 8 away from the guide sleeve 1. An ejector component 1 4 and an ejector component 2 7 are provided in the guide hole 2. A part of the ejector component 2 7 is located in the ejector hole 9. The tooling also includes a punch 11, which has a punching hole 18. A punching component 12 passes through the punching hole 18, and a part of the punch 11 can extend into the forming cavity 10.

[0020] The guide sleeve 1 has a through hole 3, which communicates with the guide hole 2. The diameter of the guide hole 2 is larger than the diameter of the through hole 3. The end of the through hole 3 away from the guide hole 2 is connected to the end of the guide sleeve 1 away from the mold core 8. The ejector component 4 includes a connected ejector rod 5 and an ejector head 6. The ejector head 6 is located inside the guide hole 2, and the ejector rod 5 is located inside the through hole 3. A portion of the ejector rod 5 protrudes through the through hole 3. The ejector component 7 includes a connected ejector head 13 and an ejector rod 14. A portion of the ejector rod 14 is located inside the ejector hole 9, and the ejector head 13 abuts against the ejector head 6. A protrusion 15 is connected to the end of the ejector rod 14 away from the ejector head 13.

[0021] The punching component 11 includes a punching block 16 and a punching head 17. The punching head 17 is located on the side close to the mold core 8. The cross-sectional size of the punching head 17 is smaller than that of the punching block 16. The punching head 17 can extend into the forming cavity 10.

[0022] A limiting hole 19 is provided at one end of the ejector hole 18 near the punch block 16. The diameter of the limiting hole 19 is larger than the diameter of the ejector hole 18. The ejector component 12 includes an ejector rod 20 and a limiting block 21. The diameter of the limiting block 21 is larger than the diameter of the ejector rod 20. The diameter of the ejector rod 20 is not larger than the diameter of the ejector hole 18. The diameter of the limiting block 21 is smaller than the diameter of the limiting hole 19 but larger than the diameter of the ejector hole 18. The cooperation of the limiting block 21 and the limiting hole 19 can limit the movement of the ejector component 12, allowing it to move to a specified position and ensuring that the product meets the corresponding production requirements.

[0024] A portion of the ejector component 2 7 extends into the forming cavity 10 through the ejector hole 9, holding the material inside the forming cavity 10 in place through the end of the ejector component 2 7. The ejector rod 5 of the ejector component 1 4 extends out of the guide sleeve 1 and connects to the external mechanism, thereby holding the ejector component 1 4 in place. During the stamping process, the ejector component 1 4 holds the ejector component 2 7 in place, fixing its position. During stamping, the punch component 11 moves towards the forming cavity 10, and the punch head 17 of the punch component 11 first enters the forming cavity 10 to stamp the material. The material is initially formed by the combined action of the end face of the punch head 17, the end face of the ejector rod 2 14, and the side wall of the forming cavity 10. Then, the ejector component 12 moves towards the forming cavity 10, and the end of the ejector component 12 stamps the material again, forming the material internally and completing the manufacturing of the product.
