Mold design and process for producing a multilayer part by injection process molding

A molding equipment for making a composite molded article comprising:

• (a) a fixed side mold having a convex portion integral with a gate, said convex portion being formed according to the shape of the molded article, said gate being used for injecting melted resin into a resin molding space;
• (b) a movable side mold capable of being moved close to and away from said fixed side mold, said movable side mold having a concave portion, said concave portion being formed according to the shape of said molded article, said concave portion being inlaid with said convex portion to form said resin molding space when said molding equipment is clamped;
• (c) a set of slide cores comprising a plurality of members being mounted between said fixed side mold and said movable side mold, said slide cores being movable toward and away from said fixed side mold, said slide cores being reciprocally movable toward and away along a near right angle direction to the moving direction of said movable side mold, said side cores forming an opening at the center when said slide cores are moved close to each other wherein said opening is smaller than said concave portion and said opening is sufficiently large for said convex portion to penetrate when said molding equipment is clamped;
• and
• (d) a skin material setting frame mounted between said fixed side mold and said slide cores, said skin material setting frame being capable of setting a skin material.
