Preparation process of metal guide plate for casting mold

Abstract

The invention discloses a preparation process of a metal guide plate for a casting mold. The preparation process is characterized in that a matrix backing layer of a concave V-shaped guide plate and a matrix backing layer of a convex V-shaped guide plate are precisely cast with low-carbon steel, thin copper alloy self-lubricating layers are arranged on inclined surfaces of the matrix backing layer of the concave V-shaped guide plate and the matrix backing layer of the convex V-shaped guide plate, steel replaces copper, and solid lubricant powder which is uniformly distributed in copper alloy replaces solid lubricant column agents. A metal guide plate prepared according to the preparation process is adopted, so that precious metal copper and nonferrous metals are saved, the metal guide plate is high in carrying capacity, fatigue strength, mechanical strength and friction and wear properties, and long in service life, energy consumption and labor are reduced, and the material cost and the production cost of the product are reduced.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a process for preparing a metal guide plate of a casting mold. Background technique [0002] The mold industry is one of the important indicators to measure the development level of the automobile industry. In recent years, although my country's automobile mold technology has developed rapidly, it is still at a low-to-middle level compared with developed countries. Many high-end automobile molds rely on imports. [0003] The oil-free self-lubricating guide plate of existing casting copper alloy inlaid graphite post, has a lot of is to inlay lubricant column on the plate with integral cast copper alloy and constitutes, and this guide plate can not adapt to the development of automobile industry. The large thick plate made of integrally cast copper alloy is generally pre-processed according to a certain arrangement, and the solid lubricant such as high-purity graphite or graphite m...

Problems solved by technology

[0003] Many of the existing oil-free self-lubricating guide plates of cast copper alloy embedded with graphite columns are composed of integral cast copper alloy embedded with lubricant columns on the plate. This guide plate can no longer adapt to the development of the automobile industry.

The large thick plate made of integrally cast copper alloy is generally pre-processed according to a certain arrangement, and the solid lubricant such as high-purity graphite or graphite material is impregnated with Babbitt alloy to form a cylinder, and then the cylinder is embedded in the prefabricated hole. Such a process requires a lot of processing equipment, many processes and is cumbersome, labor-intensive, time-consuming, and manpower-intensive; it not only wastes a large amount of scarce precious metal copper and its alloys, but also costs high
