Abstract

The invention discloses a manufacturing method of an injection mold. The method includes the following process steps: step 1: analyzing a plastic part production drawing, understanding the use of injection-molded parts and analyzing the manufacturing process of the plastic parts; step 2: using three-dimensional software to make a general assembly drawing of a plastic part mold and engineering drawings of components, and setting a mold tolerance standard; step 3: manufacturing the mold, and introducing a forging technology, a sawing technology, a jig boring processing technology and a milling technology into a CAM tool path program design; step 4: inspecting and assembling the mold; and step 5: testing the mold and repairing the mold. Through the method mentioned above, not only the overall design of the mold is optimized to ensure the reliable implementation of the follow-up process, but also the precision of the mold and the qualification rate of injection molding products are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing and processing, and in particular relates to a method for manufacturing an injection mold. Background technique [0002] Injection mold is a tool for producing plastic parts, so as to give plastic parts complete structure and precision. Injection molds generally consist of two parts, a male mold and a female mold. The male mold is installed on the movable template of the injection molding machine, and the female mold is installed on the fixed template of the injection molding machine. During injection molding, the male mold and the female mold are closed to form the gating system and the cavity, and the male mold and the female mold are separated to take out the plastic product when the mold is opened. [0003] The supply of molds with low technical content has exceeded the demand, and the market profit space is narrow. The medium and high-end molds with high technical content are stil...
