发明名称 Mold for compression molding a resin article
摘要 A mold for compression molding a resin article, which mold consists of male and female molds, wherein, at the time of complete mold closing, the length L in a mold closing direction of a mated part formed between the outermost wall of said male mold and the innermost wall of said female mold satisfies the equation:wherein t1 is a distance (mm) between the male and female molds when the resin melt first reaches the mating outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1 when the mold closing is complete, and the horizontal distance of a mating gap between the outermost wall surface of said male mold and the innermost wall surface of said female mold is from 0.02 to 0.1 mm, with which mold, squeeze-out of a resin melt during molding is prevented.
