Molding method and apparatus for producing molded foamed resin product

摘要

In a molding method for producing a molded foamed resin product (24) in which an expandable resin (21) containing a resin material containing a foaming agent is charged into a cavity (16) between a stationary mold half (3) and a movable mold half (4) and core-backing is then performed by setting the movable mold half (4) back from the stationary mold half (3) to extend the cavity (16) to a volume corresponding to the size of the molded foamed resin product (24), the core-backing speed is controlled to be higher in a latter core-backing term (Ts) than in a previous core-backing term (Tf), thereby providing a good-appearance molded foamed resin product having a skin layer over the entire surrounding surface and a homogeneous foam structure under the skin layer.
