Manufacturing method of mold

Abstract

The invention belongs to the technical field of machining, and particularly relates to a manufacturing method of a mold. The material for manufacturing the mold comprises 4-6% of silicon carbide, 5-8% of graphite, 2-3% of curing agent, 3-5% of surfactant, 4-6% of silicon dioxide, 40-50% of epoxy resin, 3-5% of plasticizer, 4-6% of montmorillonite and the balance of water. The method for manufacturing the mold comprises the following steps: pulverizing the material, forming a blank, turning the blank, carrying out high-temperature sintering, sanding, carrying out surface treatment, and carrying out spraying treatment to obtain the corrosion-resistant non-metal mold. The manufacturing method provided by the invention has the advantages of simple technique, resource saving, low manufacturing cost, abrasion resistance and corrosion resistance, and is suitable for mass production. The method enhances the toughness of the mold and prolongs the service life of the mold on the premise of keeping high damp heat resistance, chemical corrosion resistance and mechanical strength.

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. There are many types of molds, which can be divided into: ①Molds for processing metals according to the processing objects and processing technology. ②Processing non-metallic and powder metallurgy molds. Including plastic molds (such as injection molds, compression molds and extrusion molds, etc.), rubber molds and...

Problems solved by technology

[0003] Traditional mold materials are mostly metal alloy materials, but alloy molds are easily corroded by molded products or parts, which shortens the service life of the alloy mold, and often requires repair after the alloy mold has formed thousands of products or parts. touch, or even scrap

Moreover, the production cycle of alloy molds is long, and when products or parts need to be formed in large quantities, the alloy molds need to be frequently repaired or re-opened, resulting in an increase in the production cost of producing the products or parts, which is not conducive to improving the quality of products or parts.
