[0029] Please refer to Figure 1 And Figure 2 In an embodiment of the utility model, the oil tank assembly is applied to die casting machine, and the oil tank assembly includes a first oil tank 1, a defoaming assembly 12, a second oil tank 2 and a communication assembly 3;The first oil tank 1 is provided with containing groove 11 containing hydraulic oil, and the first oil tank 1 is used to supply hydraulic oil to the locking system of the die casting machine;The defoaming assembly 12 is arranged in the first oil tank 1, and the defoaming assembly 12 is used to eliminate the bubbles on the hydraulic oil in the first oil tank 1;The second oil tank 2 is used to supply hydraulic oil to the injection system of the die casting machine;And the communication assembly 3 communicates the first oil tank 1 and the second oil tank 2, and the communication assembly 3 transports the airflow in the second oil tank 2 to the first oil tank 1, to blow the bubbles on the hydraulic oil in the first oil tank 1 to the defoaming assembly 12.

[0030] The technical scheme of the utility model transports the airflow generated when the hydraulic oil in the second oil tank 2 performs injection action to the communication assembly 3, and the communication assembly 3 blows the airflow towards the defoaming assembly 12, to make the bubbles on the hydraulic oil surface in the first oil tank 1 move to the defoaming assembly 12, so that the defoaming assembly 12 blocks or eliminates the bubbles, and then eliminates the bubbles in the hydraulic oil in the first oil tank 1, to avoid the hydraulic oil with high bubble content entering the high-pressure system.

[0031] In the embodiment, the first oil tank 1 can be arranged as a mold locking oil tank, and the first oil tank 1 can be used to supply hydraulic oil to a mold locking system of the die casting machine.

The application communicates the second oil tank 2 by arranging the communication assembly 3, so that the air flow in the second oil tank 2 can be guided into the first oil tank 1, thereby solving the problem that the high air pressure in the second oil tank 2 causes the second oil tank 2 to expand, and thereby providing a power source for driving the bubbles of the hydraulic oil in the first oil tank 1 to flow to the defoaming assembly 12. By arranging the defoaming assembly 12, the bubbles or impurities on the hydraulic oil can be conveniently eliminated or blocked, thereby avoiding the bubbles and impurities in the hydraulic oil flowing into the high pressure area of the hydraulic system.
