Abstract

The invention discloses a production process of a cement-based environment-friendly mould. The production process comprises the following steps: preprocessing solid waste, mixing, carrying out injection molding, holding pressure, solidifying and moulding, demoulding, extracting and polishing. Manufacturing materials of the mould can adopt multiple materials, generally including steel, resin, ceramic and cement according to injection molding materials; as the mould is generally used, usage amount of the manufacturing materials is larger; compared with use of brand new manufacturing materials, a certain amount of recycled building solid waste is used in the raw materials for producing the mould; by combining with the production process of the cement-based environment-friendly mould, on one hand, use orientation of the building solid waste can be solved, and on the other hand, manufacturing cost of the mould is greatly reduced.

Description

technical field [0001] The invention relates to the field of mold processing technology, in particular to a manufacturing technology of a cement-based environment-friendly mold. Background technique [0002] In the mold industry, various molds and tools are used 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". There are many materials for mold manufacturing, generally including materials such as steel, resin, ceramics, and cement. In the traditional manufacturing process, brand-new manufacturing materials are used, which makes the manufacturing cost of molds relatively...
