PURPOSE:To mold integrally a reinforcing rib of closed section structure with a product by clamping SMC with dividing molds, and then inserting a blow pin into SMC, moving forward its end into a hollow section and heat compressing the SMC while air is sucked from the blow pin into the hollow section. CONSTITUTION:A bottom force 1 and a top force 2 are heated up and kept at the given temperature. Then, an SMC 5 is placed on the bottom force 1, over which another SMC 6 is overlapped. Then, two pieces of SMC 5 and 6 are clamped by the bottom force 1 and the top force 2. At the same time, a blow pin 4 is stuck into SMC 5, and the end of the blow pin 4 is stuck into a hollow section 7. While air is sucked from an end opening of the blow pin 4 into the hollow section 7, SMC 5 and 6 are heated pressed by the bottom force 1 and the top force 2. Then, SMC 5 is expanded to bond with the surface of a recessed section 3 to form a reinforcing rib 8 of closed section structure on said section. At that time, polyester resin is fluidized and integrated to form a product 9. At the state of curing the resin, air suction from the blow pin 4 is discontinued, and the blow pin 4 is released from the product 9. |
