Manufacturing method of die

Abstract

The invention discloses a manufacturing method of a die. The manufacturing method comprises the following steps: S1, configuring the raw material of the die; S2, polishing and smashing each component of the raw material in S1; S3, adding each component of the raw material into a smelting furnace for smelting in sequence in parts by weight; S4, injecting a smelting solution obtained in the S2 into a female die for pouring; S5, carrying out quenching and tempering on the die obtained in the step S4, and then putting in a room temperature environment for cooling; S6, soaking the die obtained in the step S5 into electroplate liquid for electroplating; and S7, carrying out sand blasting on the surface of the die obtained in the step S6. Through the manner, the technology is simple, the tensile strength of the die can be improved, the production product quality of the die is improved, and the appearance of the die is relatively attractive.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for manufacturing a 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 shape an object. 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". There are many types of molds, which can be divided into molds for processing metal and molds for processing non-metal and powder metallurgy according to the processing objects and processing technology. [0003] Metal molds are generally made of cast iron or aluminum. When the wo...

Problems solved by technology

[0003] Metal molds are generally made of cast iron or aluminum. When the working temperature of the mold is high, the hardness and toughness will decrease, resulting in premature wear or fatigue fracture of the mold and failure

Especially when molding plastic products or parts, due to the presence of chlorine, fluorine and other elements in the plastic, strong corrosive gases such as HCL and HF will be decomposed after heating, which will erode the surface of the mold cavity, increase its surface roughness, and aggravate wear and tear failure.
