Abstract

The invention discloses a frame-type die-casting product one-time punching device which comprises an upper die assembly and a lower die assembly, wherein first punching pins and punching heads are arranged on an upper die fixing plate of the upper die assembly; second punching pins are arranged on a lower fixing plate of the lower die assembly; positioning inserts which correspond to the first punching pins and the punching heads are arranged on the top surface of a lower die stripping plate; and during the die-casting process of a frame-type die-casting product, the frame-type die-casting product can be punched conveniently through the upper die assembly and the lower die assembly from the upper and lower sides at the same time. The frame-type die-casting product one-time punching deviceis aimed at a conventional frame-type die-casting product shut-off hole burr removing device; the working principles of a composite film and an inverted die are combined; an upper die is designed to achieve stripping in the form of ejector pins; a lower die is designed to achieve stripping in the form of springs; and compared with the prior art, the one-time punching process has the advantages that the process turnover is reduced, the die investment cost is lower than the multi-set die cost, and the actual efficiency of production is improved.

Description

Technical field [0001] The invention relates to the technical field of die-casting molds for frame products, in particular to a one-time punching device for frame die-casting products. Background technique [0002] The existing frame type aluminum alloy die castings have many through holes on the product and the distance between the holes is very small. During the production process, the parting line will flutter, and the manual removal of the product through holes is high and the efficiency is low. The existing technology generally uses a composite punching die for punching. Due to the small distance between the product through holes, a set of molds cannot be completed, and multiple sets of molds are needed to achieve the overflow of all through holes with the product runner and slag bag. Die cutting of the mouth. [0003] The existing processing technology of removing the through-holes of frame aluminum alloy die castings uses a composite punching die to punch the impact perfor...
