Abstract
PURPOSE: To improve the balance of a fan, make an air discharge hole for a motor bushing fitting hole by a shut-off pin at the same time as the closing of a port, shorten the shaping process of the fan and increase the diameter of the port.
CONSTITUTION: The port 1 is opened in a metal mold 14 at the center of the top of a cavity 8 corresponding to a spinner 11 formed on the central part of the fan 7. A shut-off gate block is composed of the metal mold 14 and the port 1. Ejection pins 4, 5 are provided at both the sieds of the cavity 8 so that the pins extend through a lower metal mold 15 and can project. The shut-off pin 17 is provided in the center of a motor bushing fitting hole making metal mold 16 behind the spinner 11 so that the shut-off pin 17 can move vertically. A resin is filled into the cavity 8 through the port 1. The tip of the pin 17 is inserted into the port 1 by an air cylinder 18 through a shut-off plate 19. Cooling or other processing is performed, thereby completing the fan 7.
