Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the deficiencies in the performance of base oil and give it certain new properties, especially for use in injection molding machines.

[0003] During the use of lubricating oil, impurities will be mixed into it, and after lubricating between mechanical parts, debris on the metal surface will be absorbed. These impurities and debris will seriously affect the quality of the lubricating oil and even cause damage to mechanical parts. Those skilled in the art have provided a lubricating oil circulation device for an injection molding machine to solve the problems raised in the above background technology. Utility Model Content

The lower end of the plate 8 is fixedly installed with connecting columns 15 near the four corners. First, the lubricating oil used in the injection molding machine is sent into the interior of the circulation frame box 1 through the oil inlet pipe 2. Through the primary filter plate 13 and the secondary filter plate 8, the lubricating oil is first filtered through the primary filter plate 13 and then leaks to the secondary filter plate 8. After starting the rotating motor 10, the cam 9 is rotated. After the cam 9 contacts the secondary filter plate 8, the secondary filter plate 8 vibrates, which facilitates the lubricating oil to quickly pass through the secondary filter plate 8, and then filter out clean lubricating oil.

[0022] In this embodiment, the interior of the connecting column 15 is connected with a steel ball 16 via a strong spring, and a return spring 17 is fixedly mounted on the lower end of the supporting column 7 .

[0023] In this embodiment, the lower end of the return spring 17 is fixedly connected to the inside of the fixing tube 6 , and a circular groove 18 is formed at the upper end of the support column 7 .

[0024] In this embodiment, a circular hole 19 is formed on the outside of the support column 7 near the top, the connecting column 15 is plugged into and matched with the circular groove 18 , and the steel ball 16 is snap-fitted into and matched with the circular hole 19 .

[0025] In this embodiment, the secondary filter plate 8 is located inside the circulation frame 1 , and rotating motors 10 are fixedly mounted on both inner walls of the circulation frame 1 .

[0026] In this embodiment, a cam 9 is fixedly mounted on one end of the output shaft of the rotating motor 10 , and the cam 9 is located at the lower end of the secondary filter plate 8 .

[0028] The implementation principle of the lubricating oil circulation device for an injection molding machine in the embodiment of the present application is as follows: first, the lubricating oil after use in the injection molding machine is sent into the interior of the circulation frame box 1 through the oil inlet pipe 2, and the lubricating oil is first filtered through the primary filter plate 13 through the primary filter plate 13 and then leaks into the secondary filter plate 8 through the set primary filter plate 13 and the secondary filter plate 8. After starting the rotating motor 10, the cam 9 is rotated. After the cam 9 contacts the secondary filter plate 8, the secondary filter plate 8 is vibrated, which facilitates the lubricating oil to quickly pass through the secondary filter plate 8 and filter out clean lubricating oil. After disassembly and cleaning, first take out the primary filter plate 13, and then rotate the support block 111 to separate the threaded rod 12 from the inner wall of the circulation frame box 1, and then pull up the secondary filter plate 8 to disengage the steel ball 16 outside the connecting column 15 from the circular hole 19, and complete the disassembly of the secondary filter plate 8, so as to facilitate the cleaning of the circulation frame box 1 and the inside of the oil receiving box 4.
