The motor 1 may be used in any kind, such as a direct current motor or an alternating current motor, and in particular, it is preferable that the deceleration motor is equipped with a deceleration device to increase the output instead of reducing the speed.

The motor 1 is provided in the upper frame 3 so that the motor shaft 1a faces directly downward. Accordingly, the screw rod 2 integrally coupled to the motor shaft 1a and the auxiliary rod 4 installed on the upper frame 3 in a direction parallel to the screw rod 2 also face downward. do.

Since the upper frame 3 is fixed to a certain height by a separate supporting means (not shown), when the motor 1 is rotated, the nut 5 is straight up and down along the screw rods 2. Is moved. As the nut 5 is moved, the lower frame 6 integrally coupled with the nut is also linearly moved up and down. At this time, the lower frame 6 is a pair of left and right auxiliary rods installed on the upper frame 3. Since it moves along (4), it can perform stable up and down linear motion.

In addition, the lower frame 6 is preferably provided with a bushing 7 so that the auxiliary rod 4 slides through the guide hole 7a penetrating through the bushing 7.

The pressure plate 8 is coupled to the lower frame 6 via a pair of pressure rods 10. In addition, the pressure plate 8 is formed with a plurality of drain holes 8a for draining excess water generated when the head is pressed and molded in the head mold 9.
