[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Combination Figure 1-4 A pneumatic pump installation structure shown includes an oil tank 1 and a pneumatic pump 2. The oil tank is a hollow rectangular cavity inside. The pneumatic pump 2 is buried in the cavity of the oil tank 1. The air inlet end of the pneumatic pump 2 is placed on the outside of the oil tank 1 to ensure that the pneumatic pump effectively contacts the external gas during subsequent work. The pneumatic pump 2 is installed in the cavity of the oil tank 1 through a partition 3. The partition 3 is fixed to the inner wall of the cavity of the oil tank 1. The partition 3 provides stable support for the pneumatic pump 2 to prevent the entire hydraulic station from shaking under the subsequent high-frequency operation of the pneumatic pump 2.

[0025] In this embodiment, the Figure 2 A sealing ring is provided at the connection between the air inlet end of the pneumatic pump 2 and the oil tank 1 to ensure that the hydraulic oil inside the oil tank 1 will not overflow from the connection during subsequent use. A shutter 4 is provided on the outer wall of the oil tank 1 at the air inlet end of the pneumatic pump 2. The shutter 4 is used to protect the air inlet end of the pneumatic pump 2 to prevent dust from entering during subsequent use and affecting normal operation.

[0026] In this embodiment, the Figure 3 The partition 3 shown is provided with a bolt hole 301, an oil hole 302 and a through hole 303. The bolt hole 301 is used to fix the pump body of the pneumatic pump 2 so that the pneumatic pump 2 is confined between the partition 3 and the oil tank 1, thereby reducing subsequent working shaking. The oil hole 302 is used for the circulation of hydraulic oil in the oil tank 1 to ensure that the addition of the partition 3 will not affect the normal internal operation. The through hole 303 is used to place the oil pressure head of the pneumatic pump 2.

[0027] In this embodiment, the Figure 4 The inner wall of the oil tank 1 shown is provided with two groups of reinforcing ribs 101 relatively to each other, and locking holes 1011 are provided on the reinforcing ribs 101. The outer wall of the partition 3 is provided with a waist-shaped groove 304 matching the locking hole 1011. The reinforcing ribs 101 are used to ensure the stable strength of the partition 3 after installation. In addition, the waist-shaped groove 304 can realize the position adjustment and fixation of the partition 3, ensuring that even if the partition 3 of a certain specification of the pneumatic pump 2 is replaced, it can still provide stable support.

[0028] A hydraulic station includes a pneumatic pump installation structure. An oil-water separator 5 is fixedly arranged on an oil tank 1. The oil-water separator 5 prevents the oil tank 1 from being affected by excessive condensed water and affecting the use effect. A valve group 6 is arranged on the other side of the oil tank 1 relative to the oil-water separator 5. The valve group 6 is used to preliminarily adjust the flow rate of hydraulic oil and is used in conjunction with air pressure. The oil-water separator 5 and the valve group 6 are both connected to the pneumatic pump 2 through a pipeline. An accumulator 7 is arranged on one side of the valve group 6 through a pipeline. The accumulator 7 is an energy storage device in the hydraulic and pneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compression energy or potential energy into hydraulic pressure or air pressure and releases it to replenish the system. When the system pressure increases instantly, it can absorb this part of the energy to ensure that the pressure of the entire system is normal.

[0029] In this embodiment, the Figure 1 The upper surface of the oil tank 1 shown is provided with a filling hole 8 and an oil return hole 9. The filling hole 8 is used to add hydraulic oil in the oil tank 1 to balance according to demand, and the oil return hole 9 is convenient for connecting an external injection molding machine to realize the circulation of hydraulic oil.

[0030] In this embodiment, the Figure 1 A liquid level gauge 10 is provided on the outer side wall of the oil tank 1 shown, so as to detect the height of the hydraulic oil in the oil tank 1 from the outside and ensure that the pneumatic pump 2 is effectively placed in the hydraulic oil.
