Wear-resistant cold-working steel mold

Abstract

The invention relates to the technical field of steel molds, and discloses a wear-resistant cold-working steel mold. The wear-resistant cold-working steel mold comprises a base, wherein a limiting groove is formed in the base, a mold cover is arranged in the limiting groove, a pouring hole runs through the mold cover, first clamping grooves are formed in the two sides of the mold cover respectively, pressing blocks are arranged on the two sides of the bottom of the mold cover respectively, threaded sleeves penetrate through the inner walls and the outer walls of the two sides of the base, threaded rods are inserted into the threaded sleeves, rotating handles are fixedly connected to one ends of the threaded rods, push rods are fixedly installed at the other ends of the threaded rods, and sliding blocks are fixedly connected to the two ends of each push rod respectively. According to the wear-resisting cold-working steel mold, the limiting groove and the sliding blocks for moving limiting are arranged at the joint of the base and the mold cover, so that the position of the die cover does not deviate when the die cover moves, the moving stroke is more stable, the ejection effect of an ejector rod is improved, the completeness of cast steel is effectively protected, the working efficiency is improved, and meanwhile, the percent of pass of products is increased.

Description

technical field [0001] The invention relates to the technical field of steel molds, in particular to a wear-resistant cold-working steel mold. Background technique [0002] Casting instead of forging is the development trend of the mold manufacturing industry today, and the mold manufacturing technology is developing rapidly. In the manufacture of automobile molds in Europe, America and Japan, the number of castings used accounts for more than 95% of the black materials used in molds. Compared with forgings, using castings to make molds can save a lot of raw materials, save CNC machining costs, reduce kinetic energy consumption, and shorten production cycles. The automotive mold manufacturing industries in developed countries such as Europe, the United States and Japan have taken the lead in using castings instead of forgings to make molds. For example, German mold manufacturing standards require the use of cast high-carbon high-alloy steel materials, such as 1.2382 cast ste...
