Main board stretching and edge-cutting composite die structure

Abstract

The invention relates to a main board stretching and edge-cutting composite die structure. The main board stretching and edge-cutting composite die structure comprises an upper module and a lower module; the upper module comprises an upper die seat and an edge-cutting upper female die which are arranged in sequence from top to bottom, the upper surface of the upper die seat is provided with a die handle, and the edge-cutting upper female die is internally provided with a stretching upper die core and an inner stripping plate; the lower module comprises a lower stripper plate, a lower fixing plate and a lower die seat which are arranged in sequence from top to bottom, the lower stripper plate and the lower fixing plate are internally provided with a stretching lower die core and an edge-cutting male die, and the stretching lower die core is arranged on the peripheral side of the edge-cutting male die in a sleeved manner. By means of the main board stretching and edge-cutting composite die structure, stretching and edge-cutting are integrated, the die manufacturing cost is lowered, and the production efficiency of a main board is improved. Since the main board stretching and edge-cutting composite die structure is put into use, qualified products can be stably produced, the design purpose is achieved, and production requirements are met.

Description

technical field [0001] The invention mainly relates to the field of molds for producing main boards in radiators, in particular to a composite mold structure for drawing and trimming main boards. Background technique [0002] The surface of the main board of the heat sink has a convex hull structure, and the edges are to be flanged. There are currently two sets of molds for the production of main boards, namely the stretching mold for the stretching process and the trimming mold for the trimming process. The cost of mold manufacturing is relatively high, and there are two steps in the process. The product needs to be artificially removed from the previous step. Moving to the next process, the production efficiency of the product is low, and there is a possibility that the product may be unqualified due to human error, so it is necessary to improve the mold structure. Contents of the invention [0003] Aiming at the above problems, the present invention provides a composit...
