PURPOSE:To enable the molded object composed of a plurality of raw materials to be made at one time by a method in which the partion plate for dividing the space in the cavity of a mold, is provided, while different raw materials are respectively supplied to both side, spaces thereof, the partion plate is retracted before the raw material is solidified. CONSTITUTION:A movable platen 11 is moved to the side of a stationary platen 10, and a male mold 16 and a core 21 are caused to enter into the female mold 12, whereby a cavity 31 is formed between both members. In this state, a control valve 27 is switched, and compressed air is supplied into an air cylinder 25. Consequently, a piston rod 26 is pushed out, and a partition plate 23 is advanced through a slit 20, whereby the space in the cavity 3 is divided in two spaces. The first foamable resin 32 and the second foamable resin 33 are respectively supplied into the cavity 31 from feeders 28, 29 by synchronization with the advance of the partition plate 23. When the control valve 27 is switched again, the raw material feeding holes of the feeders 28, 29 are closed, the partition plate 23 is retracted, and two resins 32, 33 are brought in contact with each other at their boundary in the cavity 31.
