Abstract

PURPOSE: To enable a first and second molding to be fitted to each other in connecting parts thereof by cast-molding a first material without pushing down the piston member at the first process, and withdrawing the exposed surface in pushing down the piston member at the second process, following this, cast- molding the second material into the gap in the exposed surface.
CONSTITUTION: In the first process, a first mold having a central protrusion 11 and a lower mold urged by means of a spring member 22 in its central mold surface are mold-combined, a rigid material as a first material W1 is cast-molded without pushing down the piston member 21 of the lower mold 2. In the second process, a second upper mold 3 having a projection protruding through the central opening of the first molded article P1 is combined to the lower mold 2, and as the exposed surface 21a is withdrawn in pushing down the piston member 21, the connected end of the first molded article P1 becomes to meet with the cavity C in a state of keeping a gap between the upper and lower molded surface 30a and 21a. Therein the second material W2 is cast- molded; as a result, the connected end F2 of the second molded article P2 is molded such that the connected end F1 of the first molded article is wrapped thereby.
