Embodiment 1

[0028] A kind of manufacturing method of die-casting mold provided by the present invention specifically comprises following production steps:

[0029] S1: Prepare materials. First, purchase abrasive tool steel in the market as the raw material for mold manufacturing, collect and reserve, and proceed to the next step of processing;

[0030] S2: Raw material pretreatment, the raw material obtained in step S1 is cleaned by using a high-pressure cleaning water gun, and then the method of pickling and rust removal is used. The raw material is put into the pickling tank for pickling, and the rust on the surface of the raw material is cleaned, and then cleaned by high pressure Water gun cleaning, clean the acid on the raw material, the pressure of the high-pressure water gun is 5Mpa, wash away the impurities and dust on the surface of the raw material, and finally put it in an open and ventilated place, use the fan to dry it, collect it for later use, and clean it. next step;

Abstract

The invention discloses a manufacturing method of a die-casting mold. In the method, cast steel replaces a traditional Cr12 material mold, and the die-casting mold is more resistant to high temperature and has higher strength. Before the raw material is used, the rust on the surface of the raw material is cleaned thoroughly by a method of acid pickling and rust removing, so as to facilitate the processing in the next step; a mold core size protection sleeve is processed according to the requirements of a hot sleeve, and the precision of the mold shell is controlled, the degree of finish is good, and the probability of wear is low, so that the service life of a mold core is greatly prolonged, the mold is prevented from being damaged, has high structural strength, cooperates well with an extrusion needle embedded and has long service life; the mold is provided with a positioning hole and a positioning groove for positioning, thereby facilitating rapid positioning during mold closing andimproving the efficiency of die casting.

Description

technical field [0001] The invention belongs to the technical field of die-casting molds, and more specifically relates to a manufacturing method of a die-casting mold. Background technique [0002] Mold, 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. In short, a mold is a tool used to make shaped objects. This 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. Known as the "Mother of Industry". Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineerin...
