Patent ID: 8827680

Claim:
A liquid resin material molding system comprising: an agitation-mixing mechanism for agitation-mixing of a liquid resin material having an additive added to a main component; a pump mechanism for feeding a liquid material mixture obtained thereby; a fixed-quantity metering/supply mechanism for metering a fixed quantity of the liquid material mixture fed thereto, and delivering the mixture to a downstream stage; a mold for obtaining a molded article from the liquid material mixture supplied by the fixed-quantity metering/supply mechanism; and a mold clamping device for clamping the mold, wherein the fixed-quantity metering/supply mechanism comprises: a body provided with a pot for storing the liquid material mixture fed by the pump mechanism, an inflow port through which the liquid material mixture is introduced into the pot, and an outflow port through which the liquid material mixture is discharged from the pot; a plunger displaceably attached to the body; plunger pushing means, furnished to the body, for pushing the plunger in an advancing direction; a first flow passage connecting the pump mechanism and the inflow port; an inflow valve, furnished to the first flow passage, for opening and shutting the first flow passage; a second flow passage connecting the outflow port and the mold; and an outflow valve, furnished to the second flow passage, for opening and shutting the second flow passage, the inflow port is furnished to a region offset towards the plunger pushing means from the outflow port, in an axial direction of the plunger, and the plunger is furnished with a material flow passage for directing the liquid material mixture supplied from the inflow port to a distal end of the plunger, even when the plunger is placed at a maximum advance position.
