いた。(Problems to be Solved by the Invention) In the above-mentioned injection molding machine, the number of revolutions and the screw lead in the screw mechanism determine the mold opening/closing speed, and the rotational force and the screw lead determine the mold clamping force. On the other hand, since there are limits to the rotational speed and rotational force of the electric motor, if the screw lead is constant, if you try to design a large mold opening/closing speed without increasing the capacity of the electric motor, the mold clamping force will decrease, and vice versa. This had the disadvantage that if the mold clamping force was designed to be large, the mold opening/closing speed would be reduced.

よる型開閉速度は大きくなる。 The rotational force of the electric motor 3 in this state is transmitted from the drive shaft 24 to the transmission shaft 25 via the transmission gears 26 and 27, and further to the mold clamping output shaft 28.
It is transmitted to the mold clamping drive shaft 13 through. Further, since the transmission shaft side gear 27 is smaller than the drive shaft side gear 26, the rotation on the transmission shaft 25 becomes high speed, and the mold opening/closing speed due to the thrust generated by the screw mechanism increases.

きな型締力となる。 The rotational force of the electric motor 3 in this state is transmitted to both the transmission shaft 25 and the mold clamping output shaft 28 via the two gears 30 and 32. No communication will take place. Therefore, transmission to the mold clamping output shaft 28 is performed directly from the drive shaft 24, and since the gear 30 on the mold clamping output shaft side is larger than the gear 32 on the drive shaft side, the mold clamping output shaft 28 is transmitted directly to the mold clamping output shaft 28. The rotational speed transmitted to the transmission shaft 25 is reduced, and the rotational force becomes larger than when transmitted via the transmission shaft 25. As a result, the thrust force generated by the screw mechanism becomes a large mold clamping force.
