Description

Technical Field

[0001] The utility model belongs to the technical field of die casting, and in particular relates to a die casting punch lubrication device. Background Art

[0002] The traditional punch oil lubrication in the die-casting industry is mainly achieved by setting a lubricating oil spray gun at the punch position corresponding to the outside of the material trough, and spraying the punch lubricating oil onto the punch surface for lubrication. In actual use, since one end of the punch needs to overlap the material trough mouth, the conventional lubricating oil spray gun cannot spray the lubricating oil into the end of the punch located in the material trough. Moreover, since the traditional spray gun sprays lubricating oil, it can usually only provide sufficient lubrication to the side of the punch facing the spray gun. On the side wall of the punch away from the spray gun, the spray gun structure in the prior art is obviously unable to achieve sufficient lubrication of the punch, resulting in a lubrication blind spot on the side of the punch away from the spray gun, which not only leads to waste of lubricating oil, but also causes the problem of insufficient lubrication of the punch. Utility Model Content

[0007] As a further preferred embodiment of the present invention, an oil guide is provided in at least one of the lubrication grooves, the oil guide is filled in the lubrication groove, and the end surface of the oil guide facing the side wall of the punch is flush with or higher than the lubrication channel.

[0008] As a further preferred embodiment of the present invention, the oil guide member includes one or more of an oil guide filler or an oil guide net.

[0009] As a further preferred embodiment of the present invention, at least one lubrication side groove is provided on the side wall surface of the lubrication groove, for guiding the flow of lubricating oil to the notch of the lubrication groove toward the punch.

[0010] As a further preferred embodiment of the present invention, the width of the lubrication groove along the extending direction of the punch decreases successively from the position of the oil outlet to the position away from the oil outlet.

[0011] As a further preferred embodiment of the present invention, the lubrication ring includes at least two lubrication grooves, and the lubrication grooves are arranged at intervals along the extending direction of the punch.

[0012] As a further preferred embodiment of the present invention, the oil outlet of the oil guide hole is arranged on the outer wall surface of the lubrication ring.

[0013] As a further preference of the present invention, it further comprises an oil guide pipe, wherein the oil guide pipe is a hollow pipe, one end of the oil guide pipe is connected to the oil outlet, and the other end of the oil guide pipe is used to introduce lubricating oil.

[0014] As a further preference of the present invention, it further comprises at least one connecting assembly, each of the connecting assemblies passing through the lubrication ring along the extension direction of the punch, and being used for detachable connection between the lubrication ring and the material trough.

[0015] As a further preferred embodiment of the present invention, a joint and a shooting rod are sequentially provided at the end of the punch away from the material trough, and in the projection of the extending direction of the punch, the projection of the joint is located within the projection range of the punch.

[0016] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0017] (1) The die-cast punch lubricating device of the present invention includes a lubricating ring, which is arranged at the end of the material trough facing the punch, and a lubricating channel is opened on the lubricating ring, and the side wall surface of the lubricating channel abuts the inner wall surface of the punch; the lubricating ring also includes at least one lubricating groove and at least one oil guide hole, each lubricating groove is arranged on the inner wall surface of the lubricating channel, the oil outlet of each oil guide hole is arranged on the inner wall surface of the lubricating channel, and the other end of the oil guide hole away from the oil outlet is arranged on the outer wall surface or end surface of the lubricating ring; the bottom of each lubricating groove is connected to at least a part of at least one oil outlet.

[0030] Example:

[0031] See also Figures 1-3 The die-casting punch lubrication device in the preferred embodiment of the present invention can improve the utilization rate of lubricating oil. It can not only ensure that the lubricating oil can be fully coated on the complete side wall surface of the punch 11, but also reduce the overflow of lubricating oil. While ensuring the full lubrication cost of the punch 11, it can also reduce the lubrication cost.

[0032] Specifically, if Figures 1-3 As shown in , in a preferred embodiment of the present application, a die-casting punch lubrication device is provided at the end of the hollow trough 1 facing the punch 11, so as to fully lubricate the side wall surface of the punch 11 before the punch 11 enters the hollow trough 1. The die-casting punch 11 includes a lubrication ring 2, which is provided at the end of the trough 1 facing the punch 11, and a lubrication channel 10 is provided on the lubrication ring. The lubrication channel 10 corresponds to the hollow channel of the trough 1. At the same time, the side walls of the lubrication channel 10 and the hollow channel can abut against the side walls of the lubrication channel 10. Preferably, the side walls of the punch 11 are slidably fitted with the inner wall surface of the lubrication channel 10 and the inner wall surface of the hollow pipe, respectively.

[0033] The lubrication ring 2 also includes at least one lubrication groove 4 and at least one oil guide hole 5. Each lubrication groove 4 is defined on the inner wall of the lubrication channel 10, allowing the lubricating oil within the lubrication groove 4 to fully lubricate the corresponding sidewall of the punch 11 as it passes through the lubrication channel 10. Accordingly, the oil outlet 8 of each oil guide hole 5 is located on the inner wall of the lubrication channel 10. The bottom of each lubrication groove 4 communicates with at least a portion of at least one oil outlet 8, ensuring that each lubrication groove 4 is fully filled with lubricating oil from the oil guide hole 5, ensuring that the lubrication ring 2 adequately lubricates the punch 11. The other end of the oil guide hole 5, facing away from the oil outlet 8, is located on the outer wall of the lubrication ring 2 or on the end face of the lubrication ring 2 extending in the direction of the punch 11. This allows lubricating oil to flow into the oil guide hole 5, providing sufficient lubricating oil for the lubrication ring 2 to continuously lubricate the punch 11.

[0034] Furthermore, in a preferred embodiment of the present application, an oil guide is provided in at least one lubrication groove 4. The oil guide is used to absorb and store lubricating oil, and the end surface of the oil guide facing the side wall of the punch 11 is flush with the lubrication channel 10 or the end surface of the oil guide facing the side wall of the punch 11 is higher than the lubrication channel 10, so that when the punch 11 slides through the lubrication channel 10, the outer wall of the punch 11 can contact the oil guide, ensuring that the lubricating oil stored in the oil guide can be continuously and fully coated on the side wall of the punch 11, further improving the comprehensiveness of the lubricating oil coating on the punch 11. Preferably, an oil guide is provided in each lubrication groove 4.

[0035] Further preferably, in a preferred embodiment of the present application, the oil guide member includes one or more of an oil-conducting filler or an oil-conducting mesh. Preferably, the oil-conducting filler is a filling structure such as cotton wool or a multi-gap band. Further preferably, the oil-conducting mesh is an elastic oil-conducting mesh structure. Further preferably, the oil guide member is an oil-conducting structure comprising cotton wool filled within the elastic oil-conducting mesh. During actual use, the oil guide member confines the lubricating oil, thereby preventing the lubricating oil flowing into the lubrication groove 4 from overflowing. This ensures that the lubricating oil effectively lubricates the punch 11 while also avoiding waste of lubricating oil.

[0036] In more detail, in a preferred embodiment of the present application, in order to ensure that the lubricating oil fully lubricates the punch 11, at least one S-shaped lubrication groove 4 is provided on the side wall surface of the lubrication channel 10, so that when the punch 11 is in the lubrication groove 4, more lubricating oil can be stored in the lubrication groove 4, thereby improving the lubrication of the side wall surface of the punch 11 by the lubrication groove 4. Preferably, the curvature of the S-shaped lubrication groove 4 in the lubrication channel 10 gradually becomes denser from the position close to the oil outlet 8 to the position away from the oil outlet 8, that is, the lubrication groove 4 can store more lubricating oil at the position away from the oil outlet 8. Combined with the characteristic of the faster lubricating oil replenishment rate at the position close to the oil outlet 8, the lubrication groove 4 can always have sufficient lubricating oil, ensuring comprehensive lubrication of the punch 11.

[0037] Furthermore, in another preferred embodiment of the present application, a plurality of branch grooves are provided on both sides of the lubrication groove 4. The branch grooves are arranged at an angle, which can also store more lubricating oil, thereby improving the lubrication groove 4's sufficient lubrication of the punch 11. Preferably, the branch grooves are evenly spaced along the circumference on the inner wall surface of the lubrication channel 10, and the projection of each branch groove intersects the projection of the central axis of the lubrication channel 10.

[0038] Further preferably, in the preferred embodiment of the present application, since the lubricating oil replenishment rate is faster at the position of the lubricating groove 4 close to the oil outlet 8, correspondingly, the lubricating oil replenishment rate is slower at the position of the lubricating groove 4 away from the oil outlet 8, in order to equalize the lubricating oil replenishment rate and avoid lubricating oil overflow, the groove width of the lubricating groove 4 along the extension direction of the punch 11 decreases successively from the position of the oil outlet 8 to the position away from the oil outlet 8.

[0039] More specifically, in a preferred embodiment of the present application, at least one lubricating side groove is provided on the sidewall of the lubrication groove 4 to guide lubricating oil at the bottom of the lubrication groove 4 toward the notch of the lubrication groove 4, ensuring that sufficient lubricating oil is always present at the notch of the lubrication groove 4 to lubricate the sidewall of the punch 11, thereby improving the lubrication efficiency of the lubrication groove 4 on the sidewall of the punch 11. Furthermore, preferably, a plurality of lubricating side grooves are sequentially arranged on the sidewall of the lubrication groove 4 along the inner circumference of the lubrication channel 10.

[0040] Furthermore, in a preferred embodiment of the present application, at least two lubrication grooves 4 are provided in the lubrication channel 10, and each lubrication groove 4 is spaced apart along the extending direction of the punch 11. Preferably, the lubrication channel 10 is provided with at least one lubrication groove 4 near the slot opening and near the punch 11, respectively, so that the entire sidewall surface of the punch 11 whose end is located in the lubrication channel 10 can be fully coated with lubricating oil.

[0041] Further preferably, in the preferred embodiment of the present application, the oil outlet 8 of the oil guide hole 5 is arranged on the outer wall surface of the lubricating ring 2. Preferably, the oil guide hole 5 passes through the entire lubricating ring 2 in the radial direction of the punch 11, and an oil inlet is provided at the end of the oil guide hole away from the oil outlet 8, and the oil inlet is connected to the oil guide pipe 3, and the lubricating oil is introduced into the end of the oil guide pipe 3 away from the oil inlet.

[0042] More specifically, in a preferred embodiment of the present application, the die-casting punch lubrication device further includes at least one connecting assembly 9. Each connecting assembly 9 extends through the lubrication ring 2 along the direction of the punch 11, thereby removably securing the lubrication ring 2 to the end of the trough 1 facing the punch 11. Preferably, the connecting assemblies 9 are evenly spaced along the circumference. Further preferably, the connecting assemblies 9 are connecting bolt assemblies.

[0043] Furthermore, in a preferred embodiment of the present application, a joint 6 and a shooting rod 7 are sequentially provided at the end of the punch 11 facing away from the trough 1, and, in the projection of the punch 11 in the extension direction, the projection of the joint 6 is located within the projection range of the punch 11. Preferably, in the projection of the punch 11 in the extension direction, the projection of the shooting rod 7 is located within the projection range of the punch 11.

[0044] The die-casting punch lubrication device of the present invention features a simple structure, uniform coating, and ease of use. By arranging a lubricating ring 2 at the end of the trough 1 facing the punch 11, combined with multiple lubricating grooves 4 provided in the lubrication channel 10 of the lubricating ring 2 and oil guide holes 5 connecting the lubricating grooves 4, the lubricating oil within the lubricating grooves 4 is continuously and accurately applied to the sidewalls of the punch 11 as the punch 11 slides through the lubricating channel 10, ensuring adequate lubrication of the punch 11. Furthermore, by employing S-shaped lubricating grooves 4 or multiple lubricating branches provided within the lubricating grooves 4, and by modifying the width of the lubricating grooves 4 based on the position of the oil outlet 8, sufficient lubricating oil can be stored in the lubricating grooves 4 at different locations, thereby ensuring adequate lubrication of the punch 11. Furthermore, by providing at least one lubricating groove 4 on both sides of the lubricating channel 10 along the direction in which the punch 11 extends, the lubricating oil further ensures adequate lubrication of the sidewalls of the punch 11 and improves lubricating oil utilization, thus offering promising promotional prospects and application value.

[0045] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
