Description

Technical Field

[0001] This utility model relates to the field of low-pressure casting, and in particular to a double-sided low-pressure casting device. Background Technology

[0002] Low-pressure casting equipment uses riser pipes for injection. Generally, only one riser pipe can be used for operation, resulting in low casting efficiency. If multiple riser pipes are used, not only can the efficiency of a single mold be improved, but multiple molds can also be injected simultaneously. However, multiple riser pipes can only inject at the same rate, making it difficult to control them separately for different usage conditions. In addition, it is no longer possible to inject through only one riser pipe. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-sided low-pressure casting equipment, which solves the current pain points in this field.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A double-sided low-pressure casting device includes a liquid storage tank. A partition is fixedly installed in the middle of the liquid storage tank, dividing the interior of the liquid storage tank into two pressure chambers. A riser pipe is fixedly installed in each of the two pressure chambers. An air inlet is provided on the side wall of the liquid storage tank. The center of the air inlet is located in the vertical direction of the partition, and the air inlet can supply air to the two pressure chambers. A rotating cylinder is rotatably installed on the partition. An opening is provided on the side wall of the rotating cylinder. An annular groove is provided at the outlet of the air inlet on the side wall of the liquid storage tank. One end of the rotating cylinder is rotatably installed in the annular groove, and the rotating cylinder covers the outlet of the air inlet and rotates around the air inlet.

[0006] To further explain, a motor is fixedly installed on the outside of the liquid storage tank, and the shaft of the motor is connected to the center of the rotating drum, thereby driving the rotating drum to rotate.

[0007] To further explain, a heat insulation block is fixedly installed between the motor and the liquid storage tank.

[0008] In summary, the advantages of this utility model compared to the prior art are as follows: the rotating cylinder can be moved to different angles to make the two pressure chambers separate or connected; by changing the orientation of the rotating cylinder opening, one of the two pressure chambers can be ventilated and pressurized or pressurized simultaneously, thereby realizing single-tube injection or multi-tube injection; adjusting the opening angle of the rotating cylinder can adjust the amount of gas entering the two pressure chambers at the same time, thereby controlling the injection rate in the two liquid tubes.

[0013] The utility model will be further described in detail below with reference to the accompanying drawings.

[0014] A double-sided low-pressure casting device includes a liquid storage tank 1. A partition 3 is fixedly installed in the middle of the liquid storage tank 1, dividing the interior of the liquid storage tank 1 into two pressure-dividing chambers 2. A riser pipe 4 is fixedly installed in each of the two pressure-dividing chambers 2. An air inlet 5 is provided on the side wall of the liquid storage tank 1, with the center of the air inlet 5 located vertically in the partition 3, and the air inlet 5 can vent air into the two pressure-dividing chambers 2. A rotating cylinder 6 is rotatably installed on the partition 3, and the side wall of the rotating cylinder 6 has an opening. An annular groove 7 is provided at the outlet of the air inlet 5 on the side wall of the liquid storage tank 1. One end of the rotating cylinder 6 is rotatably installed in the annular groove 7. The rotating cylinder 6 covers the outlet of the air inlet 5 and rotates around the air inlet 5. When the rotating cylinder 6 rotates so that the opening is completely on one side of the partition plate 3, the partition plate 3 and the rotating cylinder 6 separate the two pressure-dividing chambers 2. The air inlet 5 can only enter the corresponding pressure-dividing chamber 2 through the opening. When the opening of the rotating cylinder 6 is facing up or down, the two pressure-dividing chambers 2 are connected through the rotating cylinder 6. The air inlet 5 can simultaneously vent air into the two pressure-dividing chambers 2, so that pouring can be performed simultaneously from the two liquid riser pipes 4.

[0015] A motor 8 is fixedly installed on the outside of the liquid storage tank 1. The shaft of the motor 8 is connected to the center of the rotating drum 6, thereby driving the rotating drum 6 to rotate. A heat insulation block 9 is fixedly installed between the motor 8 and the liquid storage tank 1.

[0016] The above description is merely an exemplary embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The scope of protection of the present utility model is determined by the appended claims.
