High-strength mold preparation process for automatic processing

Abstract

The invention discloses a high-strength mold preparation process for automatic processing, comprising a preparation step of a mold sleeve, a preparation step of an insertion ring and a preparation step of a mold core; the mold in the process comprises the mold sleeve, the insertion ring provided on the inner side of the mold sleeve and the mold core provided on the inner side of the insertion ring; the peripheral wall of the insertion ring is provided with four L-shaped through grooves, and the four L-shaped through grooves are evenly distributed in the peripheral wall of the insertion ring. The insertion ring is arranged on the inner side of the mold sleeve, and the mold core is arranged on the inner side of the insertion ring, and no interference fit is needed between the mold sleeve andthe mold core, thereby avoiding damage to the mold sleeve and the mold core during disassembly, and ensuring the service life of the mold sleeve and the mold core; the carburization is carried out twice in the process of heat treatment of the mold, the thickness of a carburized layer is increased, and the mold has high strength performance under the pressure of concentrated pressure; and the quenching oil is improved so that the quenched mold has low roughness degree and is easy to dye and electroplate, while ensuring the quality of mold quenching.

Description

technical field [0001] The invention relates to a mold preparation process, in particular to a high-strength mold preparation process for automatic processing. Background technique [0002] Mold is a kind of various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products, that is to say, molds are used to make shaped items Tool, this kind of tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material, and makes the blank into a specific shape and size under the action of external force. The tools for parts are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as compression molding or injection molding of engineerin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength mold preparation process for automatic processing. By setting an inlay ring on the inner side of the mold sleeve, and setting a mold core on the inner side of the inlay ring, there is no need for interference fit between the mold sleeve and the mold core, which is convenient. The disassembly of the mold core prevents direct wear between the mold sleeve and the mold core during disassembly, avoids damage to the mold sleeve and the mold core, and ensures the service life of the mold sleeve and the mold core; during the heat treatment process, the mold sleeve and the inlay ring The carburizing layer and the mold core were carried out twice respectively, thereby increasing the thickness of the carburized layer on the surface of the mold sleeve, the inlay ring and the mold core, so that the mold has the high-strength performance of withstand concentrated pressure hedging, and the mold sleeve, the inlay ring and the mold core Quenching is carried out twice to greatly improve the structural defects of the mold material itself, so that the mold has better toughness; by improving the quenching oil, adding acrylonitrile-butadiene-styrene copolymer to it, not only improves Improve the impact strength of the mold, and make the surface of the mold more clean, easy to dye and electroplate on the surface of the mold, ensure the quality of the mold quenching, solve the problem of inconvenient disassembly of the mold core in the existing mold, low impact strength of the mold, and Disadvantages of short service life
