Estimating the term…
A method and a device for feeding a molten resin capable of accurately feeding the molten resin without the delay of feed timing by preventing the molten resin from adhering to route members before it seats on a mold to increase the positioning accuracy of the molten metal in the mold, and a method of manufacturing a molded part by using the fed molten resin. Vibration is provided to the route members such as molten resin guide pins (10, 40, 50), throat members (62, 70, 85), and female mold positioned in a route in which the molten resin (25) passes before it seats on the female mold (7, 63) by a vibration imparting device (27) or a gas layer film is formed on the surfaces thereof. Thus, the molten resin can be fed while preventing it from adhering to the route members.
A method for feeding a molten resin by which a molten resin is fed to a molding apparatus, wherein a route member, positioned in a route through which the molten resin passes prior to molding, is subjected to a molten resin adhesion preventing action by a molten resin adhesion preventing means, whereby the molten resin is fed to the molding apparatus, while being prevented from adhering to the route member.
A device for feeding a molten resin that feeds a molten resin to a molding apparatus, the device comprising molten resin adhesion preventing means for preventing the molten resin from adhering to a route member positioned in a route through which the molten resin passes prior to molding.
