RAW MATERIAL BEADS WEIGHT MEASURING METHOD, MOLDED BODY WATER CONTENT MEASURING METHOD AND APPARATUS THEREFOR

摘要

To provide a raw material beads weight measuring method, a molded body water content measuring method, and an apparatus therefor that can fill a cavity with a certain amount of raw material beads to produce a high-quality foam molded product without a chipped part, and can grasp a moisture content of a molded body.SOLUTION: In a method of measuring a weight of raw material beads in a foamed resin molding method, a cavity formed by a pair of concavo-convex molds 1a, 1b that can be separated from each other is filled with raw material beads, and a foamed molded product is molded by molding them by heating and foaming, and the foamed molded product is taken out by opening the mold after cooling treatment. The raw material beads are filled into the cavity from a raw material silo 3 through a measuring hopper 5. A weight of the raw material beads filled in the cavity is calculated from a weight difference of the measuring hopper 5 before and after filling by means of measuring a weight of the measuring hopper 5 before filling the raw material beads into the cavity and a weight of the measuring hopper 5 after filling the raw material beads into the cavity.SELECTED DRAWING: Figure 1
