Abstract:
1. A liquid resin molding apparatus comprising: a mold; an injection machine that injects a liquid resin material into the mold; a metering/supplying mechanism that meters the liquid resin material and supplies a metered amount of liquid resin material to the injection machine; a pump that pressure-feeds the liquid resin material to the metering/supplying mechanism, wherein the pump is a piston pump having a piston and an actuator for reciprocating the piston, and a discharge pressure of the piston pump is set to be at least 1.5 times a supply pressure with which the liquid resin material is supplied to the metering/supplying mechanism; and a pressure reducing valve disposed in a supply path extending between the pump and the metering/supplying mechanism, so as to reduce a pressure of the liquid resin material from the discharge pressure to the supply pressure.
