[0008] The cylinder body of the booster oil cylinder is integrally formed with the lifting plate, and its driving end is connected to the bottom of the workbench;

[0009] The cylinder body of the mold opening and closing oil cylinder is installed on the lifting plate, and the driving end is also connected to the bottom of the workbench.

[0010] Preferably, the cylinder body of the booster cylinder and the lifting plate are integrally cast.

[0011] Preferably, it also includes a height measuring mechanism; the height measuring mechanism includes a bracket vertically arranged at the bottom of the workbench, and a displacement sensor vertically arranged on the bracket for detecting the displacement of the lifting plate.

[0012] Preferably, it also includes a lifting mechanism; the lifting mechanism is vertically arranged at the bottom of the workbench and is located at the unloading station. When working, it can pass through the workbench and extend into the injection mold to eject the injected product.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Attached Figure 1-2The turntable low-worktable injection molding machine of the utility model comprises a worktable 1, an upper template 2 horizontally arranged above the worktable 1, a lifting plate 3 horizontally arranged below the worktable 1, three guide pillars 4 vertically passing through the worktable 1 for connecting the upper template 2 and the lifting plate 3, a turntable 5 arranged on the worktable 1 for placing injection molds, an injection mechanism 6 vertically arranged on the upper template 2, a booster cylinder 7 vertically arranged at the bottom of the worktable 1, and two mold opening and closing cylinders 8 respectively located on both sides of the booster cylinder 7;

[0023] One of the three guide pillars 4 vertically passes through the center of the turntable 5 and is placed in an isosceles triangle with the other two guide pillars 4;

[0024] The cylinder body of the booster cylinder 7 is integrally formed with the lifting plate 3, and its driving end is connected to the bottom of the workbench 1;

[0025] The cylinder body of the mold opening and closing oil cylinder 8 is installed on the lifting plate 3, and the driving end is also connected to the bottom of the workbench 1.

[0026] The utility model can lower the table height of the workbench 1 by integrally forming the cylinder body of the boosting cylinder 7 and the lifting plate 3, which is convenient for staff to operate and more user-friendly. At the same time, the two mold opening and closing cylinders 8 are directly arranged on both sides of the boosting cylinder 7, which not only has a simple structure but also can greatly reduce costs.

[0027] Furthermore, the cylinder body of the booster cylinder 7 and the lifting plate 3 are integrally cast, which not only improves product quality and production efficiency, but also reduces production costs.

[0028] Furthermore, it also includes a height measuring mechanism 9; the height measuring mechanism 9 includes a bracket 91 vertically arranged at the bottom of the workbench 1, and a displacement sensor 92 vertically arranged on the bracket 91 for detecting the displacement of the lifting plate 3; when the two opening and closing mold cylinders 8 drive the lifting plate 3 to rise and fall, the displacement of the lifting plate 3 can be detected by the displacement sensor 92, thereby calculating the height of the upper mold plate 2.

[0029] Furthermore, it also includes a lifting mechanism 10; the lifting mechanism 10 is vertically arranged at the bottom of the workbench 1 and is located at the unloading station. When working, it can pass through the workbench 1 and extend into the injection mold to eject the injected product.

[0030] Furthermore, it also includes a driving mechanism 11; the driving mechanism 11 is arranged in the workbench 1 and is used to drive the turntable 5 to rotate.

[0031] Furthermore, it also includes a positioning mechanism 12; the positioning mechanism 12 is vertically arranged at the bottom of the workbench 1, and can pass through the workbench 1 to position the turntable 5 during operation, so that the injection mold is accurately located at the injection molding station.

[0032] During operation: the driving mechanism 11 drives the turntable 5 to rotate until the injection mold to be injected moves to the injection molding station; then the positioning mechanism 12 passes through the workbench 1 to position the turntable 5 so that the injection lower mold is accurately located at the injection molding station; then the two mold opening and closing cylinders 8 drive the lifting plate 3 to drive the upper mold plate 2 to descend synchronously through the guide column 4 until the injection upper mold and the injection lower mold are molded together; then the booster cylinder 7 works, driving the lifting plate 3, the guide column 4 and the upper mold plate 2 in turn to boost and lock the injection upper mold and the injection lower mold; when the injection mechanism 6 completes the injection molding, the positioning mechanism 12 retracts into the workbench 1, and the driving mechanism 11 continues to drive the turntable 5 to rotate until the injection mold that has completed the injection molding moves to the unloading station, and at the same time, another group of injection molds to be injected also moves to the injection molding station, realizing injection molding at one station and unloading at one station, which greatly improves the work efficiency; finally, the lifting mechanism 10 passes through the workbench 1 and extends into the injection mold to eject the molded product, and works in a cycle in sequence.

[0033] Since the lifting mechanism 10, the driving mechanism 11 and the positioning mechanism 12 are all prior arts, their structures will not be described in detail.

[0034] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
