Method of controlling cooling period according to temperature of cooling water during foam molding

Abstract

Abstract PURPOSE:To prevent cooling molds from being cooled excessively in a cooling step during the foam molding, by automatically changing the delivering period of cooling water in accordance with its detected temperature. CONSTITUTION:The foaming molds comprises a core mold 10 and a cavity mold 20 for producing a component 60 from a material delivered from a material loading feeder 50. In the cooling step, cooling water is jetted from cooling water pipings 13, 23 for a prescribed period. However, since the cooling water is recovered into a pool or the like, and is used again, the temperature thereof tends to rise gradually. Accordingly, the water temperature is detected by a temperature sensor 30, the period during which magnet valves 19, 29 are opened is changed according to the water temperature through a control panel 40, and therefore the cooling molds are prevented from being cooled excessively.
