である。The hard layer 2 increases the surface hardness, improves the surface abrasion resistance and scratch resistance, and can be used as a mass-production mold without scratching the surface of the mold body 1 during press molding during mass production. In addition, the UV-curable hard coat paint that uses a polyfunctional acrylic monomer as a resin component can be cured at room temperature in a short time by irradiation with UV light, has good productivity, and has little thermal stress, so it has dimensional accuracy. Will also improve.

いため寸法精度が確保できるものである。The hard layer 2 is formed as follows. After molding the mold main body 1, the surface of the mold main body 1 is degreased and washed, an ultraviolet-curable hard coat coating is applied, the temperature is set at room temperature to 40 ° C. for several minutes, and then UV irradiation is performed within 1 minute, Let it harden. Since the paint is a one-pack type,
No need to consider pot life, there is no need for compounding, and since it is cured by ultraviolet rays, it can be performed at room temperature in a short time, high productivity, and small thermal stress ensures dimensional accuracy. Is.
