徴とする樹脂モールド装置。 In a device that pressurizes a resin tablet supplied to a pot of a mold with a plunger while heating it, and force-feeds the molten resin from the cull of the mold through a runner and a gate to a cavity in which a molded part to be resin is located, the plunger is heated. A spiral groove or protrusion is formed in the head portion to apply a rotational force about the center line of the pot to the resin tablet pressurized by the pot, and the runner is formed to extend from the periphery of the cull in a tangential direction thereof. A resin molding device characterized in that it is formed as follows.
