Guide limiting device for mold

Abstract

The invention relates to a guide limiting device for a mold. The guide limiting device for a mold comprises a guide limiting block and a guide limiting base matched with the guide limiting block, wherein the guide limit block comprises a guide limit block installation part and a guide limit block guide part which is installed at the bottom of the guide limit block installation part, the diameter of the guide limit block guide part is gradually reduced from top to bottom, and a guide cavity matched with the guide limit block guide part is formed in the guide limiting base. Compared with the prior art, a guide column guide sleeve can be replaced, the guide limiting device can be quickly installed on the mold, the problem of abnormal mold closing or interruption caused by slight shaking in the process that mold closing of an upper mold base is carried out downwards can be avoided, and the normal operation of the stamping process of the mold is ensured.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a guiding and limiting device for moulds. Background technique [0002] A general stamping die includes an upper die base and a lower die base, and a punch and a die are respectively arranged on the upper die base and the lower die base. Most of the traditional small molds use guide posts and guide sleeves to guide the punch and die to ensure that the punch and die are aligned and clamped so that they fit seamlessly, and corresponding restrictions are added nearby. Blocks to prevent mold damage caused by overtravel movement of the mold. Before installing the guide post and guide sleeve on the upper die base and the lower die base, it is necessary to process the guide post and guide sleeve installation holes at the corresponding positions respectively. The processing flow of these installation holes is as follows: machining centering hole, drilling, Rough boring, fine boring, trial...

AI Technical Summary

Problems solved by technology

In the above process, there will be certain errors in each link in the process of processing, for example: the bore of the guide post is too large, which makes the guide post unable to be installed; the debugging takes too long, which seriously affects the efficiency

In addition, if the upper mold base shakes slightly during the downward clamping process, it will cause misalignment between the guide post and the guide sleeve, making it impossible for the guide post to pass through the guide sleeve, which not only affects the normal operation of the die stamping process , will also damage the parts of the mold
