Abstract

PURPOSE: To improve the uniformity of injection molded articles and reduce the shrinkage, by means of a slug well, which communicates to the rear end via an opening thinner than the cavity rear end and forms a thicker cavity than the opening.
CONSTITUTION: The slug well 2 is preferably thinned immediately at the rear end of the molding cavity 1 and thickened in the form of a sphere, regular prism, cylinder, etc. Preferably, the thin-walled entrance of the slug well 2 is 1.5W2.0mm thick and has a land 3W5mm long. A resin, which is first packed into the runner 3 and molding cavity 1 and may cause nonuniformity due to the temperature drop, enters the slug well 2 to provide a uniform resin in the molding cavity 1
