[0002] Currently, hydraulic devices used in conjunction with molds are generally connected to the hydraulic cylinders on the mold via a single inlet and outlet pipeline. This allows the cylinders to reciprocate and drive the mold mechanisms, such as the slider and rotating mechanism. However, when multiple sets of cylinders exist in the mold, the existing single-pipeline hydraulic device cannot meet the requirements. Furthermore, prolonged operation of the hydraulic device can cause the oil pump to overheat, leading to a rise in hydraulic oil temperature and severe overheating of the equipment.

[0003] In view of this, the present invention provides a multi-oil-circuit independent control device to solve the above problems. [Summary of the Invention]

[0010] Preferably, the main oil circuit includes a main inlet oil circuit and a main outlet oil circuit, and each set of branch oil circuits includes a branch inlet oil circuit and an outlet oil circuit. The two ends of the main inlet oil circuit are respectively connected to the oil inlet of the main oil circuit valve and the branch inlet oil circuit.

The end of the branch inlet oil circuit away from the main inlet oil circuit is connected to the oil inlet of the branch valve, and the end of the outlet oil circuit away from the main outlet oil circuit is connected to the oil outlet of the branch valve.

Detailed Implementation Methods

[0017] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0018] This invention provides a multi-oil-circuit independent control device, comprising:

[0019] The frame 1 is equipped with an electrical control box 10 and an oil tank 11. The oil tank 11 is used to hold hydraulic oil and is connected to a servo oil pump 2 and a main oil valve 3. The electrical control box 10 is electrically connected to the servo oil pump 2 and the main oil valve 3.

[0020] The main oil circuit 4 is connected to the oil tank 11 at one end via the main oil circuit valve 3, and to at least one set of branch oil circuits 5 at the other end. Each set of branch oil circuits 5 is connected to a branch valve 6, and each branch valve 6 is connected to an oil cylinder (not shown in the figure). The branch valve 6 is electrically connected to the electrical control box 10.

[0021] A heat dissipation device 7 is located on one side of the servo oil pump 2 and is electrically connected to the electrical control box 10 to assist the servo oil pump 2 in dissipating heat.

[0022] The electrical control box 10 includes a human-machine interface 100, which is equipped with a servo oil pump parameter setting area, a main oil circuit valve switch, a branch valve switch, and a heat dissipation device switch. The servo oil pump parameter setting area is used to start and stop the servo oil pump 2 and to set the speed, pressure, and flow parameters of the servo oil pump 2 during operation.

[0023] The main oil circuit 4 includes a main oil inlet circuit 40 and a main oil outlet circuit 41. Each set of branch oil circuits 5 includes a branch oil inlet circuit 50 and an outlet circuit 51. The two ends of the main oil inlet circuit 40 are respectively connected to the oil inlet port 30 of the main oil circuit valve and the branch oil inlet circuit 50. The two ends of the main oil outlet circuit 41 are respectively connected to the oil outlet port 31 of the main oil circuit valve and the outlet circuit 51. The end of the branch oil inlet circuit 50 away from the main oil inlet circuit 40 is connected to the oil inlet port 60 of the branch valve. The end of the outlet circuit 51 away from the main oil outlet circuit 41 is connected to the oil outlet port 61 of the branch valve.

[0024] The branch oil passage 5 is located inside a base 8, which is fixed to the frame 1. The branch valve 6 is installed on the base 8, and the base 8 is used to support and fix the branch valve 6.

[0025] The main oil valve 3 and branch valve 6 are both solenoid valves, and the valve opening and closing and the opening and closing time are controlled by the electrical control box 10.

[0026] The hydraulic cylinder is a magnetic induction hydraulic cylinder, which has a magnetic induction element. The magnetic induction element is electrically connected to the electrical control box 10 and is used to provide feedback on the working status of the hydraulic cylinder to the electrical control box 10.

[0027] The frame 1 is equipped with casters 12 at its bottom to facilitate the movement of the device.

[0028] Specifically, by setting parameters such as the rotation speed, pressure, and flow rate of the servo oil pump 2 on the human-machine interface 100, the pressure and flow rate of the hydraulic oil pumped out of the oil tank 11 by the servo oil pump 2 are controlled. Then, by setting the opening and closing time of the main oil circuit valve 3 and each branch valve 6, the extension and retraction time of the corresponding oil cylinder is controlled, thereby controlling the stroke of other mold mechanisms such as the slider or rotating mechanism connected to the oil cylinder.

[0029] The working principle of this invention is as follows: First, the branch valve 5 connected to the hydraulic cylinder that needs to be operated is opened on the human-machine interface 100, and the main oil circuit valve 3 is opened. Then, the speed, pressure, flow rate and other parameters of the servo oil pump 2 are set. After receiving the operation command issued from the human-machine interface 100, the electrical control box 10 controls the servo oil pump 2 and the corresponding valve to perform the corresponding operation, so that the servo oil pump 2 pumps the hydraulic oil in the oil tank 11 into the main oil circuit 4 and the corresponding branch oil circuit 2, thereby causing the corresponding hydraulic cylinder to drive the corresponding mold mechanism to perform the corresponding operation.

[0030] The beneficial effect of the present invention is that the multi-oil-circuit independent control device of the present invention can independently control multiple oil cylinders in the mold, meet the actual production needs, and avoid the situation where the oil pump overheats after working for a long time.

[0031] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
