METHOD AND DEVICE FOR FEEDING MOLTEN RESIN, AND METHOD OF MANUFACTURING MOLDED PART BY USING THE FED MOLTEN RESIN

摘要

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 molding die to increase the positioning accuracy of the molten metal in the molding die, 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 dies positioned in a route in which the molten resin (25) passes before it seats on the female dies (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.
