Machining method of precision pattern insert and precision pattern insert

Abstract

The invention discloses a machining method of a precision pattern insert. The machining method comprises a cutting step of forming at least two machining holes passing through two opposite side facesof a blank at intervals in the blank, wherein two ends of the machining holes extend along a length direction of the blank, a clamping outer frame for clamping and fixing a clamp is formed on the periphery of the blank, and a middle part of the blank is partitioned by the two machining holes to form a workpiece part of which two ends are connected to the clamping outer frame; an assembly surface machining step; a machining accessory assembling step; a pattern surface primary machining step; a workpiece framework separating step; and a pattern surface secondary machining step. Through the adoption of the machining method, the problem of stress deformation after the machining of the precision pattern insert is solved, and the collapse and deformation of the edge of a pattern surface in the process is avoided. The invention also discloses a precision pattern insert machined by the method. The precision pattern insert can improve the quality and yield of mold produced products.

Description

technical field [0001] The invention relates to a processing method of a mold insert and an insert prepared by the method, in particular to a processing method of a precision pattern insert and the precision pattern insert. Background technique [0002] Inserts are irregular mold accessories specially used to be embedded in molds. [0003] In the mold, inserts can be square, round, sheet-shaped, and like all mold accessories, the requirements for precision are also very high. Generally, there is no finished product, and it needs to be customized according to the needs of the mold. [0004] During the processing of relatively slender inserts with precise patterns on the surface, the heat treatment will cause a certain degree of stress concentration on the blank, and the blank will cause a certain degree of stress release during the subsequent processing of the heat treatment, which will lead to the insert being processed. After the completion, stress deformation is very eas...
