PURPOSE:To enhance the pressing pressure of a resin material by attaching a pellet holding rod for preventing the integral rotation of a plurality of pellets to a pellet supplying unit of an injection cylinder and a leading groove to the valley of several threads of a screw of the supplying unit. CONSTITUTION:A screw 8 is turned, pellets in a hopper are supplied from a pellet throwing port 19 and a pellet holding groove 18 to the screw 8 and a leading groove 22, and are weighed by a nozzle end unit 11. In case of weighing the pellets, the integral rotation of the pellets in the screw 8 with the pellets is eliminated, the pellets are engaged with the groove 18, are effectively fed in a direction of a nozzle 11 via the groove 22, and the kneading effect of the material can be raised by the rounded part 21 of the screw 8. |
