To provide a foam molding method so that mainly the bulge of the foaming layer at the changeover portion between the self-seal part and the sandwich-seal part can be restrained.SOLUTION: The present invention relates to a foam molding method in which a core member 4 and a skin material 5 are sealed in a seal part 7 to form a foamed layer 6 inside the seal part 7. A part of the seal part 7 is formed as a self-seal part 23 in which the marginal part 22 of the skin material 5 is accommodated in the recessed part 21 provided in the core material 4, and the remaining portion of the seal part 7 is formed as a sandwich seal part 26 for sandwiching the core member 4 and the marginal part 25 of the skin material 5 with the foam molding dies 11,12. The changeover portion 27 between the sandwich seal part 26 and the self-seal part 23 is formed as a crimp seal part 29 for crimping the marginal part 28 of the skin member 5 to the core member 4.SELECTED DRAWING: Figure 7
【課題】主に、自己シール部と挟着シール部との切替部分での発泡層のハミ出しを抑制し得るようにする。【解決手段】芯材4と表皮材5とをシール部7でシールして、シール部7の内側に発泡層6を成形する発泡成形方法に関する。シール部7の一部を、芯材4に設けた凹部21に表皮材5の縁部22を収容してなる自己シール部23とし、シール部7の残りの部分を、芯材4と表皮材5の縁部25とを発泡成形型11,12で挟着する挟着シール部26とする。挟着シール部26と自己シール部23との間の切替部分27は、表皮材5の縁部28を芯材4に圧着させる圧着シール部29とする。【選択図】図7
