Problems solved by technology

[0005] Traditional casting mold covering materials are poor in product strength, wear resistance, adhesion, surface gloss and non-deformation. On the arc surface, due to the insufficient local strength of the mold, it is difficult to ensure the surface gloss of the product after CNC machining, which affects the product quality

Abstract

The invention discloses a casting mold material for numerical control processing and a mold manufacturing method. The casting mold material comprises the following parts by weight of raw materials: 30-40 parts of industrial brine, 10-18 parts of magnesium oxide, and 55-60 parts of sawdust, wherein the suitable production temperature of the casting mold material is 0 to 40 DEG C. By improving the formula of the casting mold covering material, the invention effectively improves the adaptability of the formula material to changes in the production environment, enhances the adhesion of the mold covering material to a wood frame, and improves the uniformity of coating coverage, product degree of forming and the strength of the overall mold, and can be well matched with the finishing processingof the mold product by the CNC machine tool, thereby improving the processing accuracy, quality and output of guide ring casting molds.

Description

technical field [0001] The invention relates to the production field of casting molds, in particular to a casting mold material for numerical control machining and a mold manufacturing method. Background technique [0002] With the continuous improvement of the production scale and production volume of foundry mold enterprises, as well as the continuous improvement and innovation of production technology, the problems of high turnover rate of technicians and faults in reserve forces in foundry mold enterprises have become increasingly prominent. Among them, how to reduce costs and improve Productivity and improving product quality have become the focus of attention. [0003] The traditional casting mold method is through manual drawing, manual cutting and manual assembly of the mold by technicians. The production efficiency of the product is low, the production cycle is long, the product accuracy is low (the size error value is ±2-3mm), and the outer surface of the product i...
