Description

TECHNICAL FIELD

[0001] The utility model relates to a vertical injection molding machine, in particular to a low workbench vertical injection molding machine. BACKGROUND

[0002] The traditional vertical injection molding machine installs the lower die plate below the mold locking structure (such as patent: 202020173630.X, a lower die plate device of standard vertical injection molding machine mold locking mechanism), the hydraulic cylinder force is applied to the upper die plate through the pull rod, the injection mold placed on the lower die plate is locked, in order to ensure the locking effect, the hydraulic cylinder needs enough force, the volume and height are inevitably large, so that the vertical injection molding machine is high. SUMMARY

[0003] The utility model provides a low workbench vertical injection molding machine, aims at solving the above -mentioned problem.

[0004] The utility model discloses a low workbench vertical injection molding machine, the vertical injection molding machine includes the upper die plate, lower die plate, mold locking structure, and the upper die plate is set up above the lower die plate, and the mold locking structure includes a plurality of pull rods, hydraulic cylinders, each pull rod passes through the lower die plate and is connected with the lower die plate in sliding fit, and the upper end is connected with the upper die plate, the hydraulic cylinder is installed below the lower die plate and is connected with each pull rod, drives each pull rod to move up and down synchronously, and the upper die plate moves up and down along with it.

[0005] The upper die plate moves down, and the injection mold placed on the lower die plate is locked.

[0006] Further refine the above technical solution, a bottom plate is arranged below the lower die plate, which is connected with the lower end of each pull rod, and each hydraulic cylinder is installed on the bottom plate and connected with the lower die plate through the output end.

[0007] Further refine the above technical solution, the cylinder sleeve of each hydraulic cylinder is integrally casted with the bottom plate.

[0008] Further refine the above technical solution, the hydraulic cylinder is three, one hydraulic cylinder is a high-pressure locking large hydraulic cylinder in the middle, and the other two hydraulic cylinders are small hydraulic cylinders for opening and closing the mold on both sides of the large hydraulic cylinder.

[0009] The utility model has the advantages of reasonable design, simple structure, multiple hydraulic cylinder design, force dispersion in each hydraulic cylinder, same force, smaller volume and height of each hydraulic cylinder, and the weight of each hydraulic cylinder is installed reversely (traditionally, it is installed on the lower die plate and faces down), which replaces part of the applied force by using the weight of each hydraulic cylinder and the bottom plate, so that the volume and height of each hydraulic cylinder can be smaller, and the low workbench design of the vertical injection molding machine is realized.
