Die-expanded molding apparatus and method for synthetic resin, and die-expanded molded foam obtained thereby |
摘要 |
A die-expanded molding apparatus comprising starting material bead supply for supplying beads on a current of air from a tank through a packer into a cavity formed by a core and cavity molds; a plurality of air expulsion devices having air pressure-adjusting components communicating with the cavity, a dual-system air expulsion device being such that steam chambers on the back side of the core mold and the cavity mold are used as the air pressure-adjusting components, each communicating with the cavity through through-holes formed in the core and cavity molds, respectively; an air expulsion device having one or more air pressure-adjusting components communicating with a clearance between the core and cavity molds; and a control for controlling the air pressure in each of the air pressure-adjusting components to be pressurized less than the pressure in the tank.
