Production process of precision mold

Abstract

The invention discloses a production process of a precision mold. The production process includes the following steps that screening and preliminary machining are carried out; an upper mold and a lower mold are assembled, a spigot and a positioning pin are matched, and finally a fastening bolt is used for tightening; the matched molds are subjected to machining of positioning reference holes, and the surface roughness of the holes needs to be higher than Ra 0.8; and a mold core of the upper mold is machined in an inlay welding manner, a core rod of the mold core is machined in a cylindrical grinding manner, a core head of the mold core is machined and formed through linear cutting, and the machined mold core is inserted into an upper mold inlay hole and welded and fixed at the rear end through argon arc welding. The production process of the precision mold is simple and controllable in operation and low in contamination, and meets the idea of sustainable development and cleaner production.

Description

technical field [0001] The invention relates to the technical field of mold production and manufacturing, in particular to a precision mold production process. Background technique [0002] Hydraulic molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. Specifically, a mold is a tool used to shape an article, which is composed of various parts, and different types of molds have different structures. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Therefore, the mold is an important tool in industrial production. However, the current production and processing technology of molds is still relatively traditional, which has certain pollution and does not conform to the concept of sustainable development. [0003] The traditional ...

This processing method is more suitable for the split-flow combination die with simple structure, but it is difficult to guarantee the

It is mainly affected by the machining accuracy of the electrode, the positioning accuracy of the sleeve punching process, and the control of the translational momentum. In the process of machining, the electrode positioning is often inaccurate, the electrode is burned, and the machining parameters are not well controlled, which often leads to low dimensional accuracy and poor surface quality. Poor quality, long processing cycle and other issues
