Mold in the course will always encounter some problems, use plastic molds for Curb mold materials, plastic mold is easily oxidized in air oxidation easy brittle plastic mold, plastic mold damage rate will increase, resulting in unnecessary trouble, while Curb mold can be recycled a hundred times, there may be deformed, so use will die next to prevent deformation. Also Curb mold production process errors will affect its use, production process problem is the problem of the working parts of the material, improper selection, poor material properties, do not wear; mold steel unrefined, with a large number of smelting defects, punch, forging stock change forging process is imperfect, there is heat remains hidden; structural design problems, die structure is irrational, slender punch reinforcement device is not designed, spout poor now stacking, unloading force Ambassador punch alternating loads aggravate etc; molding process is imperfect, mainly in the convex and concave forging billet inner quality is poor, heat treatment technology and process problems, resulting in convex and concave mold quenching impervious, have soft spots and hardness are. Sometimes microcracks, even cracking, grinding and polishing is not in place, the surface roughness is too large.
