摘要：A mold for injection molding of a thermoplastic resin. The mold comprises acavity block, a core block, and a cavity formed between the cavity block and the coreblock and adapted to be filled with a molten resin. The cavity block includes an insulatinglayer on a cavity side thereof, the insulating layer being made of a material selected fromthe group consisting of ceramic materials, porcelain enamel, glass materials, heatresistant plastic materials and their composites. The core block includes a releaseinsulating layer on a cavity side thereof, the release insulating layer being made of amaterial selected from the group consisting of fluorocarbon resins, fluorocarbon resincomposite materials, silicone resin composite materials and metal platings withfluorocarbon resin dispersion, the release insulating layer further being adapted toeffect both mold releasing and heat insulation.
