Pull rod mechanism of injection seat of injection molding machine

Abstract

The invention provides a pull rod mechanism of an injection seat of an injection molding machine, and belongs to the technical field of injection molding machine equipment.The injection seat of the injection molding machine comprises a machine base, a head plate and a linear guide rail, the head plate and the linear guide rail are arranged on the machine base, a slidable pull rod mechanism is arranged on the linear guide rail and connected with the head plate, and an electric injection mechanism is arranged on the pull rod mechanism. The pull rod mechanism comprises an injection table support, a motor is fixedly arranged at one end of the injection table support, an output shaft of the motor is connected with one end of a lead screw, the lead screw is sleeved with a pull rod shaft sleeve, the pull rod shaft sleeve moves front and back in the length direction of the lead screw, and one end of the pull rod shaft sleeve is fixedly connected with a lead screw nut arranged on the lead screw. The other end of the pull rod shaft sleeve is connected with one end of the pull rod shaft, and is provided with a touch component for limiting the movement of the injection seat of the injection molding machine. The pull rod mechanism of the injection seat of the injection molding machine is compact in design, small in overall size, high in precision, high in response speed, high in transmission efficiency, suitable for various injection molding machine types, convenient to assemble and beneficial to reducing the assembly cost.

Description

technical field [0001] The invention relates to the technical field of injection molding machine equipment, in particular to a tie rod mechanism of an injection seat of an injection molding machine. Background technique [0002] The existing pull rod mechanism of the injection seat of the electric injection molding machine usually adopts the mechanism of biaxial guidance and double bearing. The mechanism of biaxial guidance and double bearing is: the push plate of the injection base is supported by two guide rods, and the screw rod applied with power pushes the push plate of the injection base. The push plate of the injection base pushes the two bearing shafts to realize the forward and backward of the injection base. This structure has the problems of poor guiding accuracy and large guiding resistance, which leads to uneven injection resistance of the injection platform, slow response speed and low transmission efficiency, thus affecting the quality of injection molding, an...
