Abstract

The invention provides a part neck cold heading pattern cutting punching mold, which comprises an upper mold (1) and a lower mold, wherein the upper mold (1) can vertically move relative to the lower mold, and comprises an upper mold case (11) and a punching block (12), a lower mold concave cavity (21) capable of containing parts processed is arranged in the lower mold, a through rod (22) is vertically arranged in the lower mold concave cavity (21), penetrates through the through hole of the lower mold in a way capable of vertically sliding and extends out of the bottom of the lower mold, a neck edge cutting mold (4) is arranged on the lower mold arranged outside the lower mold concave cavity (21), and when a processed part (3) is put into the lower mold concave cavity (21), the upper mold (1) downwards moves through being driven by a driving device and extrudes the top of the processed part (3), so that the processed part (3) downwards moves to enter the lower mold concave cavity (21), and the conical neck part is cut into a pattern tooth part by a neck edge cutting mold. The part neck cold heading pattern cutting punching mold has the advantages that the pattern teeth are formed in one step, the speed is high, the effect is good, the lower end of the part to be processed is in abutted contact with the through rod, the horizontal displacement of the part to be processed is avoided, the processing is more stable, and after the pattern tooth cutting is completed, the mold stripping is more convenient.

Description

technical field [0001] The invention relates to a mold, in particular to a stamping mold for cold-heading and flower-cutting of the neck of a part used for the press molding of the part. Background technique [0002] There is an existing Chinese utility model patent with the application number CN201120204327.2 titled "Cold Heading Die for Automobile Brake Disc Shift Fork", which discloses a cold heading die for automobile brake disc shift fork, which consists of a bottom die and a moving die. , the bottom mold includes an outer mold sleeve, a mold pad and a mold core, the outer mold sleeve is composed of an upper sleeve and a lower sleeve that are threaded, the port of the upper sleeve is provided with a mold core, and the two are fixedly sleeved, and the mold pad is formed by the lower sleeve. The sleeve is pressed and fixed in the upper sleeve, and the mold pad is close to the bottom surface of the mold core. The mold core has a mold cavity with the same shape as the head ...
