Abstract

PURPOSE: To reduce the number of parts and enhance space efficiency and productivity by a method wherein a function, which allows transfer-mold molten resin in a low pressure region, and a function, which allows to injection-mold plasticized molten resin in a high pressure region, are possessed in the molding machine concerned.
CONSTITUTION: The molding process of the molding machine concerned consists of two stages or transfer molding process and injection molding process, both of which are carried out continuously or concretely performed by filling resin in the space, which is newly formed by slightly enlarging a mold cavity just after the molding at first stage, for molding at second stage. A mold consists mainly of a top force 311, a bottom force 312, a vertically movable core 313 and horizontally movable cores 315. Resin 12 for transfer molding is preheated up to a temperature not allowing to flow and, after that, introduced under molten state through a transferring port 13 into a mold cavity by being pressed with lowering transferring plunger 11 so as to be filled in the cavity for molding. After the volume of the mold cavity is enlarged by vertically and horizontally sliding the cores, resin for injection molding is injected by contacting a nozzle head part 21 with an an injection port 23 in the mold cavity so as to be filled in the cavity for molding. By carrying out both the transfer molding process and injection molding process in two continuous stages, a structural body, in which different kinds of functions are compounded, is obtained.
