Abstract

PURPOSE: To produce multilayer moldings with a couple of metal molds and a molding machine by regulating depth of cavities with pinch-off parts used as guides capable of adjusting the distance between an upper and a lower mold.
CONSTITUTION: When a couple of an upper and a lower mold 2, 1 is applied to a double-layer molding of an insulator dash, a pinch-off part 3 served also as a vertical guide of the upper mold 2 is mounted vertically along the edge part of the lower mold 1. The edge part of the upper mold 2 is fitted to the internal wall of the pinch- off part and can travel vertically along the wall. The epidermal layer of the molding, e.g., a primary cavity 5 is formed when the parting surfaces 4 of the upper and the lower mold are allowed to accord. A cavity 23 for a secondary layer is formed by lifting the upper mold 2 as far as a desired distance. Reactive resins 10, 11 are injected through an introducing hole 7 for the primary layer and through an injecting hole 8 for the secondary layer.
