DETAILED DESCRIPTION

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, an internal spray-type injection punch lubrication device for a die-casting machine includes an injection rod 1, a lubricating oil ring 6, a lubricating channel 7 and an oil outlet 10. A injection head 2 is provided at the first end of the injection rod 1, the lubricating oil ring 6 is sleeved and installed on the outside of the injection rod 1 and close to the injection head 2, the lubricating channel 7 is opened at the second end of the injection rod 1 and extends along the inner straight line of the injection rod 1 to a position corresponding to the lubricating oil ring 6, the oil outlet 10 is arranged on the outside of the injection rod 1, and the two ends of the oil outlet 10 are respectively connected to the lubricating channel 7 and the lubricating oil ring 6.

[0027] It is understandable that if Figure 3 and Figure 4As shown, the lubrication channel 7 is opened in a straight line from the second end of the injection rod 1, that is, a hole is drilled at the second end of the injection rod 1 to form the lubrication channel 7, and then an oil outlet hole 10 connected to the lubrication channel 7 is opened at a position outside the injection rod 1 close to the injection head 2, and the installed lubrication oil ring 6 is just connected to the oil outlet hole 10. In this way, the lubrication channel 7 can be set by drilling, which is simple and convenient, improves the processing efficiency of the lubrication channel 7, and reduces the manufacturing cost.

[0028] Since the second end of the injection rod 1 needs to be connected to the output end of the driving device on the die-casting machine, and the oil inlet end of the lubrication channel 7 is also located at the second end of the injection rod 1, the two may interfere with each other, thereby causing certain difficulties in the installation of the injection rod 1.

[0029] In order to solve the above-mentioned problem, one of the embodiments of the present application is as follows: Figure 4 As shown, an oil inlet hole 11 is provided outside the shot rod 1 near the second end, the oil inlet hole 11 is connected to the lubrication channel 7, and the lubrication channel 7 is provided with a seal 12 at the second end of the shot rod 1. The seal 12 can be a sealing bolt, that is, the sealing bolt can be screwed on one end of the lubrication channel 7 through a thread, thereby achieving the blocking of the right end of the lubrication channel 7, so that the second end of the shot rod 1 can be easily connected to the driving device of the die-casting machine. It should be known that at this time, the lubrication system can be docked with the oil inlet hole 11. Since the oil inlet hole 11 is provided at the side of the shot rod 1, it will not interfere with the installation of the shot rod 1.

[0030] One of the embodiments of the present application is as follows: Figure 3 As shown, a sealing component 9 can be provided between the lubricating oil ring 6 and the injection rod 1, so that the lubricating oil ring 6 and the injection rod 1 can be sealed and matched, so that the lubricating oil can be stably sprayed out from the oil injection hole 8 of the lubricating oil ring 6, and the sealing without leakage can also greatly reduce the loss of oil and improve the lubrication effect. In addition, the design of the sealing component 9 can also prevent external dust and impurities from entering the contact part between the lubricating oil ring 6 and the injection rod 1, avoid friction and wear, and extend the service life of the equipment. Through this sealing design, the normal operation of the equipment can be better protected.

[0031] As a further description of the above technical solution: Figure 3 and Figure 6 As shown, the sealing assembly 9 includes a pair of sealing grooves 902 and a pair of sealing rings 901. The sealing rings 901 can be made of rubber. Of course, there are many ways to set the sealing grooves 902 and the sealing rings 901, including but not limited to the following two:

[0032] Method 1: The sealing groove 902 is arranged outside the injection rod 1 and is symmetrically distributed with the lubricating oil ring 6 in the radial direction. The sealing ring 901 is arranged in the sealing groove 902. After the lubricating oil ring 6 is sleeved and installed outside the injection rod 1, the lubricating oil ring 6 and the sealing ring 901 are in abutment with each other, thereby achieving sealing.

[0033] Method 2: The sealing groove 902 is arranged inside the lubricating oil ring 6 and is symmetrically distributed with respect to the radial direction of the lubricating oil ring 6. The sealing ring 901 is arranged in the sealing groove 902. After the lubricating oil ring 6 is sleeved and installed on the outside of the injection rod 1, the sealing ring 901 and the outside of the injection rod 1 are in abutment with each other, thereby achieving sealing.

[0034] It should be noted that when the second method is adopted, the sealing groove 902 needs to be set inside the lubricating oil ring 6, which will cause certain difficulties in processing and is not convenient for maintenance; when the first method is adopted, the annular sealing groove 902 is set outside the injection rod 1, which is convenient for processing and maintenance and replacement; therefore, the first method is preferably adopted, but both methods can meet actual needs, and technicians in this field can choose according to actual conditions.

[0035] One of the embodiments of the present application is as follows: Figure 3 As shown, the oil injection hole 8 arranged outside the lubricating oil ring 6 is inclined toward the direction of the injection head 2, so that the lubricating oil sprayed from the lubricating oil ring 6 will be sprayed toward the injection head 2, thereby enabling the sprayed lubricating oil to be fully utilized and improving the lubrication effect. The inclined setting of the oil injection hole 8 can ensure that the sprayed lubricating oil can accurately cover the surface of the injection head 2, increase the contact area between the lubricating oil and the injection head 2, and further improve the lubrication effect. At the same time, the inclined setting can also prevent the lubricating oil from being sprayed onto other parts that do not need lubrication, thereby avoiding waste.

[0036] like Figure 7 As shown in Figure a, it is the structure of the lubricating oil ring 6 in the prior art, which is an integral annular structure, which is not convenient for installation, and is installed in a sleeve manner during the installation process. In this way, when the lubricating oil ring 6 is axially moved and installed along the injection rod 1, the sealing ring 901 in the sealing assembly 9 may also be displaced.

[0037] In order to solve the above-mentioned problem, one embodiment of the present application is as follows: Figure 5 As shown, the lubricating oil ring 6 comprises a pair of semi-ring bodies 601, and the corresponding two ends of the two semi-ring bodies 601 are provided with mounting portions 13. During installation, the two semi-ring bodies 601 are matched and connected through the mounting portions 13, thereby forming a closed structure.

[0038] Specifically, Figure 7As shown in FIG. b, the mounting portion 13 includes a plurality of mounting holes 1301 and bolt assemblies. The mounting holes 1301 are provided at both ends of the two semi-ring bodies 601. The bolt assemblies cooperate with the mounting holes 1301, that is, the bolt assemblies can pass through the mounting holes 1301 on the two semi-ring bodies 601, and then be tightened, thereby achieving the docking installation of the two semi-ring bodies 601, thereby forming a complete annular structure. This installation method ensures a stable connection between the semi-ring bodies 601, and also facilitates the operability of the installation.

[0039] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
