Ｆさせることにより、色替え、樹脂替えが終了する。In FIG. 2, when pressure oil is supplied from the hydraulic source to the high torque morph 5, the screw 2 rotates and the resin is plasticized to the plasticizing stroke amount that is stored in advance in the control device 7, and the resin is transferred to the screw 2. is pushed out into the space l at the tip of the plasticizer, and the position detector 6 sends a signal indicating the completion of plasticization to the control device 7. Next, pressure oil is supplied to the injection cylinder 4 from a hydraulic source (not shown), the screw 2 moves forward, and the molten resin is air-shot. The following operations are automatically repeated by turning on a selection switch (not shown). The raw materials for the next production are put into hopper 3,
The above operation is performed until the charged resin is air shot (the operator visually confirms that the raw material exchange has been completed). Then, when it is confirmed that the color or resin has changed, turn the selection switch OFF.
By F, the color change and resin change are completed.

Equipped with a function that automatically changes the color and stops the resin change operation when the air sizing is completed for the number of times divided by the stroke, and the plasticizing stroke required for changing the color and changing the resin by changing the set resin weight. The operator turns the switch for color change and resin change to O.
All you have to do is turn it down to N, and the work time can be shortened.

支障はない。Furthermore, with the plasticizing stroke S required for one shot stored in advance, the total plasticizing stroke ST of the first embodiment is
The total plasticizing stroke l - number of strokes NT is calculated by dividing, and the number of strokes N of the stroke number counter (not shown) is
The color change and resin change may be completed when the number of times NT is reached. Furthermore, in both of the above embodiments, even if the plasticizing operation is in progress, the resin in the space 1 at the tip of the screw has already been updated to a new color and resin, so there is no problem.
