发明名称 Injection mold
摘要 An injection mold is disclosed which includes cavities, resin passages for feeding resin toward the cavities and gates for injecting resin fed through the resin passages into the cavities. The gates each are arranged in a manner to be deviated from each of the cavities, so that only a part of an opening of the gate at an end of the gate facing the cavity is open to the cavity. Such construction, when tensile force is applied between a molded article and an in-the-gate molded resin portion to release the molded article from the mold, facilitates separation therebetween while keeping the in-the-gate molded resin portion from being left on a side of the molded article.
