Abstract
PURPOSE: To obtain the mold for molding small articles of plastic capable of preventing the small molded form molded by said mold from being attracted to the split surfaces of the mold due to static electricity or the like by a method wherein a multitude of recesses are provided on the split surfaces of the mold.
CONSTITUTION: In the mold wherein the split surfaces 2 of the mold are attached in parallel with a direction of gravity and the split surfaces of the fore and aft molds are opened and closed in the horizontal direction, for example, a multitude of fine grooves 10, 11 are engraved longitudinally and transversally to form them on the lower half of the gravity sides of the split surfaces of the mold as if they are the caramel surfaces of a candy. The fine grooves 10, 11 are engraved so as not to arrive at the recessed rim of the female mold and the protruded stand-up rim or the like of the male mold. As a concrete example, the fine grooves 10, 11 of 1mm in the width and 0.2W0.3mm in the depth thereof are provided with 2mm spaces in the up- and-down direction and 5mm spaces in the left and right direction thereof. The fine grooves are engraved on the lower halves of a fixed side template 4 and a movable side template 6.
