Abstract
PURPOSE: To manufacture a multicolor soft molded article having excellent external appearance with uniform bonding surface by providing in communication with a gate hole a recess capable of absorbing excessive pressure (excessive injecting material) when different color material is injected and filled.
CONSTITUTION: A gate hole 3 communicating a pattern recess 2 with the rear surface of a molded body 1 of soft high molecular material having the recess 2 on the surface is formed, and a fine groove 7 communicating with a gate hole 3 is formed on the rear surface of the molded body 1 (reference numeral 10 represents a runner groove). Then, this is engaged within a set space 11 formed of stationary mold 5a and a movable mold 5b to form a cavity 12 with the inner wall surface of the space 11 and the pattern recess 2. Subsequently, high molecular material of a tiue different from the molded body 1 is injected to the spool 13 of the stationary mold 5a, and is filled in the cavity 12 through the gate hole 3 (in which excessive material is flowed into the fine groove 7), and the multicolor soft molded article can be obtained with surface formed in the pattern 14.
