Highly-stable composite die base material

Abstract

The invention relates to a highly-stable composite die base material. The material contains an additive and a carrier, and the formula of the material comprises 0.5-6 wt% of modified rubber particles,10-35 wt% of unsaturated polyester resin, 1-10 wt% of sands, 0-3 wt% of a processing aid, 0-2.5 wt% of a flame retardant, 5-20 wt% of a foaming agent, 10-20 wt% of a stabilizer and 30-60 wt% of lightburnt magnesium powder. The product prepared through the method has the advantages of excellent stability, avoiding of lateral displacement of a die in the heating and pressurizing process, low basehardness, avoiding of die scrap directly caused by misoperation of die loading and unloading, low cost and high cost performance.

Description

technical field [0001] The invention discloses a more stable composite mold base material. Background technique [0002] The mold is a precision tool with a complex shape and bears the swelling force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing. In the actual use of the mold, usually the direct operation of the molding machine directly acts on the upper mold of the mold, and the work is completed by heating, pressurizing, and passing water through the molding machine. However, in the existing technology, most of the bases for placing the mold can only It plays the role of supporting the mold, so when the mold is heated and pressurized, it is easy to cause the mold to move sideways, and the base is too hard. When the upper and lower molds are misoperated and placed incorrect...

When the upper and lower molds are misoperated and placed incorrectly, the mold is easily scrapped.
