Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silicone punching devices, specifically to a silicone inner hole three-dimensional punching device. Background Technology
[0002] There are various manufacturing processes for silicone products, with compression molding being the most common. This process primarily involves using molds, and the shape of the mold determines the shape of the silicone product. Compression-molded silicone products typically undergo vulcanization, internal wall foaming, and then internal hole punching. Figure 1 In the production of silicone products, one vertical wall of the product needs to be punched. The existing punching equipment has a die edge that conforms to the product shape, but the punch punches the vertical wall of the product, which may lead to tearing of the product, which is not conducive to the production of silicone products. Utility Model Content
[0003] To address the drawback of existing punching devices that increase the likelihood of tearing when punching the vertical walls of silicone products, this invention provides a three-dimensional punching device for silicone inner holes, which reduces the likelihood of tearing when punching the vertical walls of silicone products.
[0004] This utility model provides the following technical solution:
[0005] It includes an upper die base and a lower die base, which are slidably connected by a guide rod and a guide sleeve. A punch pad and a punch fixing plate are sequentially pressed onto the upper die base, and a die pad and a die fixing plate are sequentially pressed onto the lower die base. A punch for punching irregular holes and a punch for punching round holes are installed side by side on the punch fixing plate. Corresponding to the punch for punching irregular holes and the punch for punching round holes, a die for punching round holes and a die for punching irregular holes are provided on the lower die base. The die for punching round holes and the die for punching irregular holes are installed on the die fixing plate by a die pad. The characteristic feature is that the vertical surface treatment angle C of the punch for punching irregular holes is set to eight degrees.
[0006] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0007] In this device, the vertical cutting punch with an 8-degree angle is more suitable for vertical wall punching of products. Compared with traditional punching methods, the possibility of product wall tearing during punching is greatly reduced, which helps to improve the production efficiency of enterprises.

[0013] This utility model provides, for example Figure 1 The silicone internal hole three-dimensional punching device shown includes an upper die base 1 and a lower die base 6, which are slidably connected by a guide rod and a guide sleeve. A punch pad 2 and a punch fixing plate 3 are sequentially pressed onto the upper die base 1, and a die pad 5 and a die fixing plate 4 are sequentially pressed onto the lower die base 6. A punch for punching irregular holes and a punch for punching round holes are installed side by side on the punch fixing plate 3. Corresponding to the punch for punching irregular holes and punching round holes, a punch for punching round holes and a punch for punching irregular holes are provided on the lower die base 6. The punch for punching round holes and the punch for punching irregular holes are installed on the die fixing plate 4 through a die pad 12. The vertical surface treatment angle C of the punch for punching irregular holes is set to eight degrees.
