Description

Technical Field

[0001] This utility model relates to injection molding machines, specifically to a high-speed injection table for a vertical injection molding machine. Background Technology

[0002] Traditional high-speed firing platforms, due to structural limitations, require pressure sensors to bear a large weight, at least the weight of the base and the drive unit (motor, synchronous pulley set) mounted on the base, which has a significant impact on the back pressure feedback of the stored material. Utility Model Content

[0003] This invention proposes a vertical injection molding machine high-injection stage, which aims to solve the above-mentioned problems.

[0004] The technical solution of this utility model:

[0005] A high-speed injection stage for a vertical injection molding machine includes a barrel assembly, a base, a shaft, a coupling, a pressure sensor, a drive device A, and a drive device B. The base is mounted above the barrel assembly, and the shaft is mounted on the base. The coupling is mounted on the lower end of the shaft and connected to the screw of the barrel assembly. The pressure sensor is mounted on the bottom of the base and fixed to the coupling. Drive device A is mounted on the base and connected to the shaft, driving the shaft to rotate, which in turn rotates the screw of the barrel assembly (storages material). Drive device B is connected to the base and drives the base to move up and down, which in turn moves the screw of the barrel assembly up and down (injection). The coupling is slidably fitted to the lower end of the shaft; preferably, the coupling and the lower end of the shaft are slidably connected by a spline.

[0006] This separates the base, the drive unit A mounted on the base, and the pressure sensor. During material storage, only the weight of the screw coupling and the screw of the feed tube assembly, as well as the resistance of the spline connection, need to be overcome, thus improving the back pressure feedback accuracy of the pressure sensor. (When the screw of the feed tube assembly moves up and down, the base carries the pressure sensor, the pressure sensor carries the coupling, and the coupling carries the screw of the feed tube assembly.)

[0007] To further refine the above technical solution, the driving device A is a motor, and the shaft is the output shaft of the motor.

[0008] Further refining the above technical solution, the drive device A is composed of a motor and a synchronous pulley set.

[0009] Further refining the above technical solution, the driving device B is a plurality of hydraulic cylinders.

[0010] Further refining the above technical solution, the drive device B includes a motor, a synchronous pulley set, and a lead screw assembly. A base plate is installed above the base, and the motor, synchronous pulley set, and lead screw assembly are installed on the base plate. The synchronous pulley set connects the motor and the lead screw assembly. The lower end of the lead screw assembly is connected to the base through a connecting plate and several connecting rods. Each connecting rod is suspended above the connecting plate, avoiding the drive device A and leaving space. When the drive device A is composed of a motor and a synchronous pulley set, the space left facilitates the replacement of the synchronous belt of the synchronous pulley set.

[0011] To further refine the above technical solution, both drive device A and drive device B use motors as power sources, and the motors are offset to one side during installation. The launching platform also includes a hopper group, which is offset to one side. The two motors and the hopper group are staggered and located on three sides to avoid the overall center of the launching platform being excessively offset to one side.

[0012] The advantages of this utility model are that it has a reasonable design, simple structure, and high accuracy in material storage back pressure feedback. Attached Figure Description
