INJECTION APPARATUS OF THERMOSETTING RESIN

摘要

PURPOSE: To provide an injection apparatus capable of sufficiently letting the gas generated when a thermosetting resin raw material is plasticized escape from the raw material and capable of injecting the thermosetting resin raw material without allowing the raw material to flow backward. CONSTITUTION: A raw material transfer member 40 wherein a shutter plate 41 is formed on the outer surface of a raw material transfer cylindrical part 45 having an inner diameter larger than that of a plasticizing metering cylinder 20 is provided between the leading end of the plasticizing metering cylinder and a plunger in a freely movable manner so that the raw material transfer cylindrical part is positioned in communication with the leading end of the plasticizing metering cylinder when a raw material is sent out of the leading end of the plasticizing metering cylinder and the shutter plate closes the leading end of the plasticizing metering cylinder at a times of plasticizing metering and injection while the raw material transfer cylindrical part is positioned in communication with a plunger cylinder 30.
