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

摘要

PROBLEM TO BE SOLVED: To mold a complex-shaped container component having high dimensional accuracy, excellent smoothness and different wall thickness by an impact molding method in one step. SOLUTION: A die having a cavity having a predetermined shape for placing a material to be molded and a material to be molded which is arranged to face the die and collide with the material to be molded placed in the cavity. This is an impact forming die consisting of a punch that plastically deforms the container, and the punch forms a peripheral contact surface and a thick container wall that can be peripherally contacted with the inner peripheral surface of the die in order to form a thin container wall. It is composed of a non-peripheral contact surface that does not contact the die, and the non-peripheral contact surface is provided with a step that allows peripheral contact with the inner peripheral surface of the die. Impact molding for molding complex-shaped container parts with different wall thicknesses. It is a mold. The relationship between the coefficient of friction of the die (μD) and the coefficient of friction of the punch (μP) is μD ≧ 2 × μP. [Selection diagram] Fig. 5
