Description

Technical Field

[0001] The utility model relates to the technical field of stripping dies, in particular to a die structure with a tapered surface added to reduce product stripping force. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] In the existing molds, the product is easily stuck to the punch during the stamping and stretching process, resulting in the product not being able to be released. This cannot efficiently increase production capacity and cannot meet customer demand for products. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a mold structure with an increased conical surface to reduce the product demoulding force, which has the advantage of convenient demoulding and solves the problem that the product is easily stuck on the punch during the stamping and stretching process of the existing mold, resulting in the product not being demolded, which cannot efficiently improve production capacity and cannot meet customer demand for products.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a die, a punch, a fixing hole and a fixing block, the punch is arranged at the top of the die, the fixing holes are opened on both sides of the top of the die, the fixing block is fixedly connected to the top of the punch surface, and a pusher assembly is opened at the bottom of the fixing block.

[0006] As a preferred embodiment of the utility model, the pusher assembly includes a receiving groove, the receiving groove is opened at the bottom of the fixed block, and one end of a spring is fixedly connected to the outer side of the top of the inner wall of the receiving groove.

[0007] As a preferred embodiment of the utility model, the bottom of the punch surface is movably connected to a discharge block, and the other end of the spring is fixedly connected to the top of the inner wall of the discharge block.

[0008] As a preferred embodiment of the present invention, a groove is provided at the bottom of the unloading block.

[0009] As a preferred embodiment of the present invention, a circular hole is provided on the top of the inner wall of the groove.

[0010] As a preferred embodiment of the present invention, a conical block is fixedly connected to the bottom of the punch surface.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model sets a concave die, places the product on the concave die, and then moves the punch downward to stamp the product into a required shape. The pusher assembly can push the product down when the punch moves upward after stamping to avoid the product remaining on the punch. It is more convenient to use and solves the problem that the product is easily stuck on the punch during the stamping and stretching process of the existing mold, resulting in the product not being removed from the material, which cannot efficiently improve the production capacity and cannot meet the customer's demand for the product. It has the advantage of convenient material removal.

[0013] 2. The utility model provides a pusher assembly, and the spring can be stored through the storage groove. When the punch is downward, the die blocks the unloading block, and then the fixed block and the punch continue to move downward to punch the product and squeeze the spring, so that the storage groove can store the squeezed spring.

[0014] 3. The utility model sets a discharge block. When the punch moves upward after the punching is completed, the discharge block is pushed downward by the spring, so that the discharge block pushes the product down, avoiding the product being stuck on the conical block and causing the product to not be removed.
