[0016] The following is a detailed description of the invention of the utility model by way of examples in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Example

[0017] like Figure 1 As shown, the utility model provides a hydraulic mold disassembly and assembly machine, including a workbench 1 and a hydraulic cylinder 6, wherein columns 2 are arranged at four corners of the top surface of the workbench 1, and the tops of the four columns 2 are connected to the same crossbeam 3, and the bottom of the crossbeam 3 is connected to a support plate 5 by bolts 4, and a center hole is opened on the plate surface of the support plate 5, and the hydraulic cylinder 6 is arranged on the support plate 5, and the hydraulic cylinder 6 is supported by arranging bolts 4 and the support plate 5, and the center hole on the support plate 5 facilitates the plunger in the hydraulic cylinder 6 to make up and down linear motion; the upper cavity and the lower cavity in the hydraulic cylinder 6 are connected, and the upper cavity and the lower cavity are connected to the integrated cartridge valve block 9 by a return pipe 7 and an ejection pipe 8 respectively, and the integrated cartridge valve block 9 is installed on an oil tank 10, and an electric motor 11 is arranged on the oil tank 10.

[0018] In this embodiment, the oil tank 10 is an open-type separated rectangular hydraulic oil tank, which is mainly composed of a tank body, a tank cover, an oil suction pipe, an air filter, an oil return pipe, a liquid level gauge, a partition and a filter, etc. It is mainly used to store sufficient hydraulic working medium required by the hydraulic transmission system and provide installation positions for various components.

[0019] The motor 11 is a cage-type AC three-phase asynchronous motor, which can make the hydraulic oil move and convert mechanical energy into fluid energy.

[0020] Furthermore, in this embodiment, a main nut 12 is provided at the upper end of the column 2, and the main nut 12 is located on the top of the crossbeam 3. An adjusting nut 13 is provided at the lower end of the column 2, and the adjusting nut 13 is located on the top surface of the workbench 1. By setting the adjusting nut 13, the height of the hydraulic cylinder 6 can be adjusted, thereby realizing the replacement of the inner ring and bearing of molds of different heights.

[0021] Furthermore, in this embodiment, a through hole 14 is provided at the center of the top surface of the workbench 1, so that when the plunger of the hydraulic cylinder 6 is pressed downward, it is convenient for the bearing and the inner ring to be separated from the mold.

[0022] Furthermore, in this embodiment, the integrated cartridge valve block 9 is integrated with a pressure valve, a one-way valve and a relief valve for controlling and adjusting the liquid flow pressure and changing the liquid flow direction.

[0023] Working principle: the mold is placed above the through hole 14 of the workbench 1, and the motor 11 sends the hydraulic oil in the oil tank 10 into the integrated cartridge valve block 9. The hydraulic oil forms high-pressure oil through the pressure valve on the integrated cartridge valve block 9, and is unidirectionally conducted through the one-way valve to enter the ejector pipe 8; when the high-pressure oil enters the lower chamber of the hydraulic cylinder 6 through the ejector pipe 8, the pressure in the lower chamber is greater than the pressure in the upper chamber, which will eject the plunger in the hydraulic cylinder 6, and the plunger moves linearly downward to realize the disassembly and assembly of the mold inner ring and the bearing; the high-pressure oil gradually enters the upper chamber through the channel between the lower chamber and the upper chamber. At this time, the pressure in the upper chamber is greater than the pressure in the lower chamber, the plunger in the hydraulic cylinder 6 retracts, and the plunger moves upward, and finally the high-pressure oil flows back to the oil tank 10 through the return pipe 7.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and application concept of the present invention, which should be covered by the protection scope of the present invention.
