Mold for complex-shaped container component, complex-shaped container component and manufacturing method thereof

摘要

PROBLEM TO BE SOLVED: To mold a container part having a complicated shape with high dimensional accuracy and excellent smoothness and different wall thickness by an impact molding method in one step. Kind Code: A1 A die having a cavity of a predetermined shape for placing a material to be molded, and a material to be molded which is disposed so as to face the die and is made to collide with the material to be molded placed in the cavity. And a punch for plastically deforming the punch.The punch is for forming a thick wall portion and a peripheral contact surface that can be circumferentially contacted with the inner peripheral surface of the die to form a thin wall portion of the container. It is composed of non-circumferential contact surface that does not circumscribe the die, and the non-circumferential contact surface is provided with a step that can make circular contact with the inner peripheral surface of the die. Impact molding for molding container parts with different wall thickness. It is a mold. The relation between the friction coefficient (μD) of the die and the friction coefficient (μP) of the punch is μD≧2×μP. [Selection diagram] Fig. 5
