Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as Figure 1 to Figure 19As shown, the single oil cylinder driving device of this embodiment includes an oil cylinder 2 and an oil cylinder driving module. A transmission seat 4 capable of connecting an injection molding screw is arranged at the end of the piston rod 26 of the oil cylinder 2, and the propulsion chamber 21 of the oil cylinder 2 is connected to the return The retreat chamber 22 communicates with the cylinder drive module through pipelines respectively, and the cylinder drive module is used to change the oil pressure difference between the advance chamber 21 and the retreat chamber 22 to drive the piston rod 26 to advance and retreat. The seal is provided with a rotating mechanism, one end of the rotating mechanism is connected to the piston rod 26 in transmission, and the piston rod 26 can slide back and forth relati...

Abstract

A single-oil-cylinder drive device comprises an oil cylinder and an oil cylinder drive module. A transmission seat is arranged at the end of a piston rod of the oil cylinder, and a propulsion cavity and a retreating cavity communicate with the oil cylinder drive module through pipelines. A rotation mechanism is arranged in the propulsion cavity in a sealed manner, one end of the rotation mechanismis in transmission connection with a piston rod, and the piston rod can slide back and forth relative to the rotation mechanism. The other end of the rotation mechanism extends out of the oil cylinder and is in transmission connection with a hydraulic motor. The hydraulic motor is used for driving the rotation mechanism to drive the piston rod to rotate relative to an oil cylinder block, and thehydraulic motor communicates with the oil cylinder drive module through the pipeline. The oil cylinder drive module is connected with the control module through a line. The oil cylinder drive module can be controlled by the control module to switch to drive the piston rod to move forward and backward and drive an output shaft of the hydraulic motor to rotate. The single-oil-cylinder drive device has the advantages that the control module controls oil channels to be automatically switched, the injection molding efficiency is high, the drive module can both push and pull a lead screw to conductinjection molding and drive the lead screw to rotate for rubber melting, and the use effect is good.

Description
