Title: System for automatically regulating mold thickness in toggle type mold clamping device
Inventor: KAMIGUCHI MASAO
IPC: B22D17/26
Filed: 1988-04-27
Abstract: PURPOSE:To make no overcurrent flow in a motor for regulating mold thickness and at the same time shorten mold thickness regulating time by a method wherein mold touch is done under the state that the position of the crosshead of a toggle mechanism is at the position back from the set mold clamping force position under the condition that the output torque of a servomotor is limited. CONSTITUTION:Through a toggle mechanism, the advance of a rear platen 3 causes the retreat of a movable platen 4. In addition, a crosshead 5a is retreated so as to further bend the links of the toggle mechanism 5. The above-mentioned motions are done by rotating a servomotor, the torque of which is controlled. When the amount of error becomes not less than the predetermined amount, the advance of the rear platen 3 is stopped, assuming the mold touch takes place. When the position of the crosshead 5a advances to the set mold clamping force position under the condition that the speed of the servomotor 13 is controlled so as to be equal to the driving speed of a general purpose motor 12 for regulating mold thickness in order to make the advancing speed of the movable platen 4 and the retreating speed of the rear platen 3 nearly equal to each other, the drivings of both the motors are stopped. Thus, the position of the rear platen 3 is determined and positioned under the conditions that the mold 1 is in touch and at the same time the position of the crosshead lies at the set mold clamping force position, resulting in easily finishing the regulation of mold thickness.
