Processing Technology of Male and Female Dies

Abstract

The invention discloses a processing technique of core inserts and cavity inserts, belonging to the technical field of mold manufacturing. The processing technique comprises the following steps: providing a whole blank of a core insert and a cavity insert; processing a precise locating hole in the whole blank; cutting the whole blank at a remnant material reserving position in the middle position of the whole blank; assembling the back surfaces of the cut core insert and the cut cavity insert oppositely, precisely locating to fix the positions of the core insert and the cavity insert and clamping to fix the core insert and the cavity insert; processing four side walls and the cutting surface of each of the core insert and the cavity insert; disassembling the core insert and the cavity insert and processing the thicknesses of the core insert and the cavity insert respectively; and processing according to the precise locating hole access in the subsequent work procedures. The processing technique can ensure the mold clamping precision of the cavities of the core insert and the cavity insert, and can reduce the processing and assembling errors caused by the conventional mode and can meet the requirement on the appearance of the high-precision products.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing, and in particular relates to a processing technology for male and female mold cores. Background technique [0002] The mold core is a precision part used for the key operation of the central part of the mold, which is divided into a male mold core and a female mold core. When the mold is injected, the male mold core and the female mold core are closely matched to form a closed space, which communicates with the injection molding machine through the gate and runner. After the injection material is heated, it enters the closed space through the runner and the gate. After the injection material cools down, the male mold core and the female mold core are separated, and the injection molded product is taken out. [0003] The degree of cooperation between the male mold core and the female mold core is directly related to the product quality, so the general mold is designed with a guide and ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a processing technology for the male and female mold cores, so as to solve the problem that when the existing mold cores are processed, the male mold cores and the female mold cores are prepared separately, which causes the male mold cores and the female mold cores to cooperate. When there is a certain dislocation phenomenon, the technical problem that cannot meet the mold requirements of high-precision products
