Through its reliable anti-pollution function, the anti-pollution device for oil pipe joints of high-pressure die-casting molds has become an indispensable important component in modern industrial production.
[0003] During the implementation of this application, it is found that there are the following problems with this technology: The existing oil pipe joints do not have components designed to prevent the backflow of oil fluid, which may lead to oil fluid pollution, may also affect the stable operation of the hydraulic system, increase the risk of equipment failure, and at the same time, the oil pipe installation method is unstable, resulting in easy loosening or leakage at the oil pipe connection.
[0004] Therefore, an anti-pollution device for oil pipe joints of high-pressure die-casting molds is proposed. Content of the Utility Model
[0005] The purpose of the utility model is: In order to prevent the oil fluid from being polluted and ensure the stable connection of the oil pipe, this application provides an anti-pollution device for oil pipe joints of high-pressure die-casting molds.
[0006] The technical solution adopted by the utility model is as follows:
[0007] An anti-pollution device for oil pipe joints of high-pressure die-casting molds includes a joint chamber. An oil outlet is provided on the outer surface of the right side of the joint chamber. A flow channel is arranged inside the joint chamber, and the outlet of the flow channel communicates with the oil outlet. A limiting inner frame and a limiting outer frame are integrally formed on the left side of the joint chamber, and the limiting outer frame is located on the periphery of the limiting inner frame. A limiting chamber is integrally formed on the outer surface of the side of the limiting outer frame away from the joint chamber.

An oil pipe is arranged between the limiting inner frames. A limiting ring is arranged around the periphery of the oil pipe. A limiting external thread is arranged around the outer surface of the side of the oil pipe close to the joint chamber, and two first through holes are symmetrically arranged on the outer surface of the side of the oil pipe away from the limiting external thread.
[0009] Further, the outer surface of the limiting external thread is rotationally connected to the inner surface of the limiting internal thread, and movable frames are provided on the outer surfaces of one side of the pressing chamber away from the limiting chamber. A pressing rod is slidably connected to the inner walls of the two movable frames.
[0010] Further, a fixing plate is fixedly connected to the inner walls of the two pressing chambers, and each pressing rod passes through the corresponding fixing plate. A spring is arranged around each pressing rod.
[0011] Further, a movable ring is arranged around the other end of each pressing rod, and the two ends of the spring are respectively fixed on the outer surfaces of the movable ring and the fixing plate.

[0015] 1. In the present utility model, when an oil pipe joint of a high-pressure die-casting mold with an anti-pollution device is used for oil transportation during work, the oil pipe is inserted into the inside of the limiting inner frame, and the corresponding limiting external thread and limiting internal thread are rotationally fixed through rotation. When the two groups of first through holes correspond to the corresponding second through holes, the rotation stops. During the process of the oil pipe being inserted into the inside of the limiting inner frame, by pulling the corresponding pressing rod, the spring around it is compressed, and the pressing rod moves the corresponding limiting convex block, so that the oil pipe moves stably inside the limiting inner frame. After the oil pipe stops being inserted, release the corresponding pressing part. Due to the elastic action of the spring, the corresponding limiting convex block will rebound again and form a position limit with the corresponding limiting ring again, ensuring the stable connection of the oil pipe.
[0016] 2. In the present utility model, the output port of the oil outlet is connected to another group of oil pipes. When the two groups of first through holes correspond to the corresponding second through holes, the oil liquid reaches the second through holes through the first through holes and converges inside the flow groove, and finally flows into the next oil pipe through the oil outlet. The rotational connection of the limiting internal thread and the limiting external thread ensures the tightness of the oil pipe. By rotating the oil pipe, the corresponding positions of the first through hole and the second through hole can be adjusted, preventing the backflow phenomenon of the oil liquid and effectively preventing the oil liquid from being polluted.

Specifically, through the cooperation of the above structures, the quality of the oil liquid in the production process can be improved, the oil liquid can be prevented from being polluted, and the stable connection of the oil pipe can be ensured.
[0024] Referring to Figures 1-4, the outer surface of the limiting external thread 8 is rotationally connected to the inner surface of the limiting internal thread 11. On the outer surface of one side of the pressing chamber 20 away from the limiting chamber 4, movable frames 9 are provided. A pressing rod 6 is slidably connected to the inner wall of each of the two movable frames 9. Specifically, the pressing rod 6 moves the corresponding limiting convex block 16, enabling the oil pipe 5 to stably move inside the limiting inner frame 15. A fixing plate 17 is fixedly connected to the inner wall of each of the two pressing chambers 20, and each pressing rod 6 passes through the corresponding fixing plate 17. A spring 18 is arranged around each pressing rod 6. Specifically, due to the elastic action of the spring, the corresponding limiting convex block 16 will rebound again.
[0025] Refer to Figures 1-4 , on the outer periphery of the other end of each pressing rod 6, a movable ring 19 is provided, and the two ends of the spring 18 are respectively fixed on the outer surfaces of the movable ring 19 and the fixing plate 17. Specifically, by pulling the corresponding pressing rod 6 to compress the spring 18 around it, the pressing rod 6 moves the corresponding limiting convex block 16, enabling the oil pipe 5 to stably move inside the limiting inner frame 15. A limiting convex block 16 is fixedly connected to the other end of each pressing rod 6 on the other side, and each limiting convex block 16 is in limiting clamping connection with the corresponding limiting ring 10.

By rotating 5, the corresponding limiting external thread 8 and limiting internal thread 11 are limited and fixed. When the two groups of first through - holes 7 correspond to the corresponding second through - holes 14, stop rotating. During the process of inserting the oil pipe 5 into the limiting inner frame 15, by pulling the corresponding pressing rod 6 to compress the spring 18 around it, the pressing rod 6 moves the corresponding limiting convex block 16, enabling the oil pipe 5 to stably move inside the limiting inner frame 15.

[0029] On the other hand, the outlet of the oil outlet 13 is connected to another group of oil pipes. When the two groups of first through holes 7 correspond to the corresponding second through holes 14, the oil fluid converges inside the flow groove 12 after reaching the second through holes 14 through the first through holes 7, and finally flows into the next oil pipe through the oil outlet 13. The rotational connection of the limiting internal thread 11 and the limiting external thread 8 ensures the tightness of the oil pipe. By rotating the oil pipe 5, the corresponding positions of the first through hole 7 and the second through hole 14 can be adjusted, preventing the backflow of the oil fluid and effectively preventing the oil fluid from being polluted.
