Problems solved by technology

[0002] With the development of science and technology, the scope of mold application is becoming more and more extensive. For the manufacture of product molds with multiple varieties, small batches or frequent updates and modifications, such as injection molds, blow molds, and compression molds, it is required to have manufacturing The characteristics of short cycle, low manufacturing difficulty and low cost, while the steel mold usually used in the prior art has high manufacturing cost, long cycle, and relatively low cost of alloy materials, so it is widely used in the field of manufacturing such molds
However, pure metals cannot meet the requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve their physical and mechanical properties.

Abstract

The invention relates to a die alloy. The die alloy comprises, by weight, 2-5 parts of Cr, 10-15 parts of Fe, 12-18 parts of talcum, 6-10 parts of W, 12-15 parts of Si, 8-10 parts of Ca and 2-3 parts of Nb. The die alloy has the advantages of scientific and reasonable component proportions, high wear resistance and strength, substantially prolonged service life, making cost reduction, and enterprise demand meeting.

Description

Technical field [0001] The invention relates to a die alloy. Background technique [0002] With the development of science and technology, the application range of molds is becoming more and more extensive. For molds such as injection molds, blow molds, compression molds and other molds that produce multiple varieties, small batches or frequently updated and modified products, it is required to have manufacturing The characteristics of short cycle time, low manufacturing difficulty and low cost, while the steel mold mold generally used in the prior art has high manufacturing cost, long cycle, and relatively low cost of alloy materials, so it is widely used in the field of manufacturing such molds. However, simple metals cannot meet requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve their physical and mechanical properties. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Summa...
