Abstract
PURPOSE: To obtain a metal mold which achieves effectively economy of material and energy, even if at a low capacity and a low injection-pressure, by following method in which a part of wall shaping a mold cavity is composed of a material being able to be deformed elastically along a part where a sink mark is formed liably in a forming metal mold, thereby preventing shrinkage cavities in formed articles.
CONSTITUTION: For instance, a groove 11 is formed in a fixed side mold 10 at an intersection of a space 8 and 9 in a metal mold provided with a cavity space composed of a space 8 corresponding to a flat plate and a space 9 corresponding to a rib. Consequently, when the compression molding of a resin is carried out, the groove 11 is deformed larger than the other parts, and excessive resin is accumulated, thereby preventing the sink mark of the molded resin by means of gradually recovering the deformation of the groove 11 in cooling and solidification stage.
EFFECT: Decreasing the weight of molded resin and improvement of appearance are simultaneously achieved. Material economy and cost down are expected, and then the rank of an injection molding machine is able to be lowered. The space and cost of said device are saved.
