[0002] Injection molding machines, also known as injection molding machines or injection machines, require continuous lubrication and maintenance during the injection molding process to ensure normal operation and reduce wear. Lubrication effectively reduces friction and wear between moving parts, extending the service life of the machinery. This oil-spraying self-lubricating device can recycle the waste lubricating oil generated during the injection molding process, greatly reducing the customer's production costs. At the same time, it lubricates the articulated boom hinge at all times, reducing wear at the hinge and improving the machine's service life.

[0003] Currently, there are numerous publicly available patents related to injection molding machines. For example, the technical solution of Chinese patent document (publication number: CN208074550U, patent name: A self-lubricating system for injection molds) discloses that "an injection molding machine includes an injection mold, an oil tank, a throttle valve, an oil drip pipe, an oil collection box, an oil delivery pipe, and an oil pump; the oil tank is disposed above the injection mold; the throttle valve is disposed between the injection mold and the oil tank; the oil tank, the throttle valve, and the injection mold are sequentially connected by the oil drip pipe; the oil collection box is disposed below the injection mold; and the oil pump is connected to the oil tank through the oil delivery pipe."

[0004] Based on the description and drawings in the patent document, the lubricating oil in the oil tank of the self-lubricating system is dripped into the injection mold through a throttle valve to lubricate the surface of its friction parts. However, this lubrication method is not efficient enough and cannot distribute the oil evenly on the parts that need lubrication. Utility Model Content

Through the first oil-spraying component and the second oil-spraying component, the oil-spraying holes are accurately dripped into the lubrication holes of the boom hinge, so that the lubricating oil is evenly distributed on the parts that need lubrication.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figures 1 to 2 As shown, an oil-spraying self-lubricating device includes a first oil-spraying component 4 and a second oil-spraying component 5. One end of the first oil-spraying component 4 is connected to the second oil-spraying component 5, and the other end of the first oil-spraying component 4 is connected to a self-lubricating power component 2. The self-lubricating power component 2 is connected to an oil tank 3, and the oil tank 3 is connected to an oil receiving tray 6. The oil receiving tray 6 is located below the first oil-spraying component 4 and the second oil-spraying component 5. An installation space for the boom lift 101 of the injection molding machine 1 is left between the first oil-spraying component 4, the second oil-spraying component 5 and the oil receiving tray 6. Both the first oil-spraying component 4 and the second oil-spraying component 5 are provided with a plurality of oil-spraying holes 7 corresponding to the lubrication hole positions 1011 of the boom lift 101. Lubricating oil... The self-lubricating power assembly 2 draws oil from the oil tank 3 into the first oil spraying assembly 4 and the second oil spraying assembly 5, and then flows from the oil spraying hole 7 to the lubrication hole 1011, thereby lubricating the boom lift hinge 101. After lubricating the boom lift hinge 101, the lubricating oil gradually drips onto the oil receiving tray 6, and then flows from the oil receiving tray 6 back to the oil tank 3 for recycling. The first oil spraying assembly 4 and the second oil spraying assembly 5 are fitted onto the boom lift hinge 101 to ensure that the lubricating oil can accurately flow into the lubrication hole 1011, thereby lubricating the moving joint of the boom lift hinge 101. In addition, the multiple oil spraying holes 7 can make the lubrication efficiency higher and make the lubricating oil evenly distributed on the parts that need lubrication.

[0029] Specifically, if Figure 3 As shown, the self-lubricating power assembly 2 includes a lubricating oil cylinder 201, a piston rod 202 is slidably connected inside the lubricating oil cylinder 201, and a first connecting member 203 is connected to the end of the lubricating oil cylinder 201. The self-lubricating power assembly 2 is similar to the principle of liquid aspiration by a syringe. When the piston rod 202 is pulled out from the lubricating oil cylinder 201, a low-pressure area is formed inside the lubricating oil cylinder 201, causing the lubricating oil to rise along the first connecting member 203 and enter the first connecting member 203. At the same time, it enters the first oil spraying assembly 4 through the first oil spraying assembly 4 and then enters the second oil spraying assembly 5, thereby completing the oil spraying operation on the articulated boom hinge 101.

[0030] like Figures 4 to 7As shown, the first connector 203 is provided with a first connecting hole 2031 and a second connecting hole 2032. The first connecting hole 2031, the second connecting hole 2032, the first connector 203, and the conveying pipe 201 are connected together. The first oil spraying assembly 4 includes a first connecting pipe 401. One end of the first connecting pipe 401 is connected to a second connector 402, and the other end of the first connecting pipe 401 is connected to a first tee fitting 403. The two ends of the first tee fitting 403 are connected to first oil spraying pipes 404. The second connecting member 402, the first connecting pipe 401, the first tee fitting 403, and the first oil spraying pipe 404 are connected together. The second oil spraying assembly 5 includes a second connecting pipe 501, which is connected to a second tee fitting 502. The two ends of the second tee fitting 502 are connected to second oil spraying pipes 503. The second connecting pipe 501, the second tee fitting 502, and the second oil spraying pipes 503 are connected together. Oil spraying holes 7 are arranged along the length of the first oil spraying pipe 404 and the second oil spraying pipe 404. On the oil pipe 503, the second connector 402 is provided with a third connecting hole 4021 and a fourth connecting hole 4022. The first connecting hole 2031 is connected to the third connecting hole 4021 through an oil pipe check valve, and the fourth connecting hole 4022 is connected to the second connecting pipe 501 through an oil pipe check valve. An oil inlet 301 is provided above the oil tank 3, and a cavitation groove 302 is provided on the side of the oil inlet 301. A filter element 303 is correspondingly provided below the cavitation groove 302. The second connecting hole 2032 is open to... The oil pipe check valve is connected to the filter element 303. The oil receiving pan 6 has an oil outlet 601 at its end, which is connected to the oil inlet 301. The lubrication cylinder 201 is provided with a first fixing member 204, and the piston rod 202 has a second fixing member 205 at its end. The first fixing member 204 is used to fix it to the stationary part of the injection molding machine 1, such as the frame or base. The second fixing member 205 is used to fix it to the moving platen on the injection molding machine 1, which is driven by the articulated boom 101 to reciprocate.

[0031] The working principle is as follows: During the operation of the injection molding machine 1, the boom lift 101 drives the template to reciprocate, thereby driving the self-lubricating power assembly 2 to open and close. When the boom lift 101 unfolds, the piston rod 202 is pulled out from the lubrication cylinder 201, creating a low-pressure area inside the lubrication cylinder 201. This causes the lubricating oil in the oil tank 3 to be filtered by the filter element 303 and then enter the first connecting member 203 through the pipe via the second connecting hole 2032. The lubricating oil entering the first connecting member 203 will then enter the second connecting member 402 through the first connecting hole 2031 and the third connecting hole 4021 for diversion. A portion of the lubricating oil will enter the first connecting pipe 401, and then through the first tee fitting 403 into the first oil spray pipe 404, where it drips oil onto a portion of the lubrication holes 1011 through the oil spray holes 7. Another portion of the lubricating oil enters the second connecting pipe 501, then through the second three-way fitting 502 into the second oil spray pipe 503, and drips oil onto the other part of the lubrication holes 1011 through the oil spray holes 7. When the boom lift 101 retracts, the piston rod 202 is pushed back and enters the lubrication cylinder 201, and the air pressure in the lubrication cylinder 201 is restored, stopping the oil extraction. Since the filter element 303 is equipped with a one-way valve, the extracted oil will not flow back into the oil tank 3, but the lubricating oil dripping on the boom lift 101 gradually flows into the oil receiving plate 6, and then flows back into the oil tank 3 through the oil outlet 601. After being filtered by the filter element 303, it can be recycled. Moreover, this structure is organically integrated into the reciprocating motion of the moving template of the injection molding machine 1 itself. The design is ingenious, requiring no additional power mechanism and reducing the cost of use.

Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
