20120231104 | LIQUID RESIN MATERIAL MOLDING SYSTEM - A liquid resin material molding system includes a mold, a mold clamping device for clamping the mold, and a supply device for supplying a liquid resin material to the mold. The supply device includes an agitation-mixing mechanism for agitation-mixing of a liquid resin material of an additive added to a main component, a pump mechanism for feeding the liquid material mixture obtained thereby, and a fixed-quantity metering/supply mechanism for metering a fixed quantity of the liquid material mixture fed thereto via a first flow passage by the pump mechanism, for intermittent supply to the mold through a second flow passage. | 09-13-2012 |
20130302468 | LIQUID RESIN MOLDING SYSTEM - A liquid resin molding system includes a mold clamping mechanism, an injection nozzle for injecting a liquid resin into a cavity within a mold, a nozzle touch mechanism for pressing the injection nozzle against the mold, and a liquid resin feeding apparatus disposed separately from the injection nozzle for feeding a liquid resin to the injection nozzle. The injection nozzle and the nozzle touch mechanism are attached to a movable platen. | 11-14-2013 |
20130309350 | INJECTION MOLDING APPARATUS - An injection molding apparatus includes, as its drive sources, an electric power supply source, compressed air source and hydraulic pressure supply source. A hydraulic-pressure-supply-destination selection section supplies hydraulic pressure from the hydraulic pressure supply source to a selected one of first and second mold clamping cylinders. Necessary capacity of the hydraulic pressure supply source can be lowered as compared to a case where all of the mold clamping mechanisms and injecting machines are driven by hydraulic pressure. Because only a selected one of the mold clamping mechanisms is driven at a time, the necessary capacity of the hydraulic pressure supply source can be halved as compared to a case where the mold clamping mechanisms are driven simultaneously. | 11-21-2013 |
20140134286 | LIQUID RESIN MOLDING APPARATUS - In a liquid resin molding apparatus including a mold, an injection machine, a metering/supplying mechanism for metering a liquid resin material and supplying a metered amount of liquid resin material to the injection machine, and a pump for pressure-feeding the liquid resin material to the metering/supplying mechanism, 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. A pressure reducing valve is disposed in a supply path extending from the piston pump to the metering/supplying mechanism, so as to reduce a pressure of the liquid resin material from the discharge pressure to the supply pressure. | 05-15-2014 |
20140196807 | INJECTING MACHINE FOR TWO DIFFERENT LIQUIDS - An injecting machine for two different liquids is configured to inject a liquid mixture of the two different liquids in a first-in first-out manner. The liquid mixture passes from a passage of an injection cylinder through a helical groove of a plunger into a forward space formed forwardly of the plunger as the plunger gradually moves back. When the plunger reaches a fully retracted position, a first part of the mixture remains in a front portion of the forward space while a last part of the mixture remains in a rear portion of the forward space. As the plunger moves to an advanced position, the first part of the mixture is first injected out of a nozzle and the last part of the mixture is finally injected out of the nozzle. | 07-17-2014 |
20140198600 | INJECTING MACHINE FOR TWO DIFFERENT LIQUID MATERIALS - An injecting machine for two different liquid materials includes an injection cylinder having a nozzle disposed on a distal end thereof, a mixing mechanism disposed on the injection cylinder for mixing the two different liquid materials together to feed a liquid mixture into the injection cylinder, and a support plate supporting a proximal portion of the injection cylinder. The mixing mechanism includes a valve casing fixed to the injection cylinder so that the entirety of the mixing mechanism is supported by the injection cylinder. | 07-17-2014 |
