PROBLEM TO BE SOLVED: To provide a foaming mold constituted so as to form a cavity by two molds and unnecessary for individually fixing a raw material injection head, and a foam molding machine capable of performing efficient molding using the foaming mold. SOLUTION: Respective boxes 7a having a C-shaped cross-sectional shape are fixed to either of the two molds. A slide member 7c is inserted in each of the boxes 7a through a coil spring 7b. The upper surface of the slide member 7c is formed into a tapered shape and, when the nozzle 6a of the raw material injection head 6 is pressed to a pair of the slide members 7c, the slide members 7c are opened to permit the insertion of the nozzle 6a. After a raw material is injected in the cavity formed by two molds from the raw material injection head 6, the nozzle 6a is detached. At this time, the insertion port 7 constituted of a pair of the slide members 7c is closed by the action of an elastic body 7b. A pair of the slide members 7c function as lids at the time of foaming of the raw material. COPYRIGHT: (C)2005,JPO&NCIPI |
