Problems solved by technology

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 edge 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

Abstract

The invention relates to a composite mold structure for stretching and edge trimming of a main board, comprising an upper die set and a lower die set; The upper surface of the seat is provided with a mold handle, and the upper die for trimming has a built-in drawing upper mold core and an inner stripping plate; the lower mold group includes a lower stripping plate, a lower fixing plate and a lower stripping plate arranged in sequence from top to bottom The mold base, the lower stripping plate and the lower fixing plate are built with a stretching lower mold core and a trimming punch, and the stretching lower mold core is sleeved on the peripheral side of the trimming punch. The invention combines stretching and trimming into one, reduces mold manufacturing cost and improves the production efficiency of the main board. Since it was put into use, it has been able to produce qualified products stably, achieving the purpose of design and meeting the requirements of production.

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...
