Abstract
PURPOSE: To shorten a molding time and to prevent from deformation occurring when molding, by a method wherein a large thickness part is previously molded so that a thin thickness part is allowed to leave, and after said previously molded product is set in a mold, the previously molded product and the thin thickness part are molded monolithically.
CONSTITUTION: After previoulsy molded products 16 and 17, in which fixture bolts 15, 15 are embedded, are molded so that thin thickness part 14, 14 of large thickness part 12 and 13 are allowed to leave, the previously molded products 16 and 17 are placed in a cavity 19 formed by molds 18, 18 which are formed in a shape of a rim molded product 11. A rim reaction liquid is then poured into the cavity 19, and it is solidified for molding during the lapse of 30secW2.5min. The molds 18, 18 are then opened, and a rim molded product 11, in which the previously molded products 16 and 17 and the thin thickness part 14 are molded monolithically, is removed from the inside of the cavity 19, and a mold releasing agent is applied on the cavity 19. The rim reaction liquid is constituted such that a polyore mixture liquid and 50W120pts.wt. of isocianate are mixed.
