Aluminum alloy die casting piece trimming die with smooth cut

Abstract

The invention discloses an aluminum alloy die casting piece trimming die with a smooth cut. The aluminum alloy die casting piece trimming die comprises an upper die, a lower die, a guide structure arranged between the upper die and the lower die, a product positioning structure arranged on the lower die, and a trimming cut arranged on the upper die. A hollow cavity is formed below a lower die fixing plate and internally provided with a support plate capable of moving up and down, the support plate is provided with a return rod and a plurality of support rods for supporting a feeding handle, the upper ends of the return rod and the support rods extend out of the upper surface of the lower die and is connected with the lower die in a sliding manner, a compression rod is arranged at a position of the upper die, which corresponds to the return rod, and an elastic reset element is arranged between the support plate and a lower compression plate of the lower die. According to the aluminum alloy die casting piece trimming die disclosed by the invention, when the punching is conducted, the feeding handle is kept at the horizontal state all the time, so that the cut of a product after being punched is smooth and orderly; and when the punching is conducted, the product is ejected synchronously so as to be easy to take out, and the surface of the product is avoided from damaging; and a guide pillar and a guide sleeve can be disassembled conveniently, and the guide pillar is not easy to break.

Description

technical field [0001] The invention relates to a stamping die, in particular to an edge trimming die used for trimming aluminum alloy die castings. Background technique [0002] For the aluminum alloy die-casting parts that are fed from the side of the product, the feed handle connected to the edge of the product will be left after forming, which is usually removed by manual cutting and trimmed with a tool such as a grinder to Make the surface energy of the product meet the requirements. In order to improve work efficiency, people will design and manufacture a trimming die specially used for trimming and trimming, which includes an upper die, a lower die and a guide structure. The product positioning structure adapted to the contour is used to place products that need to be trimmed. The product positioning structure usually also includes a positioning rod with a certain taper at the end, so that the product can be accurately positioned automatically by using the forming ho...
