徴とする射出成形金型のゲート形状。 In an injection mold in which the gate for injecting molten resin supplied from a sprue into a cavity is a film gate, the film gate is connected to a runner part to which the film gate is connected to the sprue, a gate part to which the cavity is connected, and a runner part. It is connected to the gate part, and is formed in a wide approximately triangular shape with the runner part side as the apex and the gate part side as the base. The gate shape of an injection mold is characterized by a part being formed deeper than other parts.
