A mold structure of a motor socket on a die-cast automobile generator shell and its operation method

Abstract

The invention discloses a die structure of a motor plugging column formed on an automobile generator shell by die casting. The die structure is provided with an insert forming an F-shaped plugging column by die casting and an ejection rod bolt, wherein the ejection rod bolt is fixed with the bottom of the insert and supports against the insert; the ejection rod bolt and the insert form an ejection rod bolt displacement angle insert part. The invention also relates to an operation method for the die structure. According to the die structure disclosed by the invention, the structure of the die insert is reformed; by related matching of the ejection rod bolt and the insert, the casting thickness of the F-shaped plugging part of a casting can be controlled, inborn defects, brought by the structure of products, of a die casting process are made up, the local quality of the products is improved, and the scrap rate is reduced.

Description

technical field [0001] The invention relates to a die-casting mold structure and an operating method, in particular to a die-casting mold structure and an operating method for a motor connecting column on an automobile alternator casing. Background technique [0002] Dimensional defects at inserts in die-casting are common, and errors are unavoidable. Dimensional deviation in die-casting has always plagued the die-casting industry. In the die-casting of automobile alternator housing, one of the key parts is a plug post for installing a micro-motor on the housing, which requires high precision and is F-shaped, such as figure 1 and figure 2 Marked in the middle circle. Because it is used to insert micro motors, if the accuracy does not meet the requirements, the motor will not fit or loosen. Therefore, the accuracy requirements are usually within a few wires. At present, because it is impossible to fine-tune the insert in the processed mold, in order to produce a qualifie...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a die-casting mold structure and its operation method for the F-type plug-in post on the automobile alternator housing, to improve the local structure of the insert, and to utilize the connection between the ejector bolt and the insert. Cooperate with each other to adjust the thickness of the die-casting product plug-in column, and completely solve the phenomenon that the inserts in the die-casting cannot be fine-tuned and the product size is not good. The method is flexible and can be used in normal production.
