Description

Technical Field

[0002] Engineering plastic bearing mold processing refers to the production of plastic bearing components used for support and friction reduction through precision injection molding or machining. Mold design must consider material wear resistance, dimensional stability, and load-bearing capacity. Key structures include guide pillars and guide sleeves, whose mating clearances must be strictly controlled, and lubrication measures must be employed to reduce friction and wear, ensuring smooth movement. The machining process requires optimization of the cooling system and draft angle to avoid deformation, ultimately meeting the high-precision, long-life industrial application requirements.

[0003] In the processing of engineering plastic bearings, molds are usually used to shape the bearings. However, traditional molds lack timed automatic lubrication functions for the guide pillars and guide sleeves, which means that workers must manually participate in the lubrication operation. This reliance on manual intervention not only increases the workload, but may also affect the lubrication effect between the guide pillars and guide sleeves due to untimely or uneven lubrication, thereby reducing the accuracy and service life of the mold.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Reference Figure 1-6 This embodiment of the present invention provides an automatic lubrication device for processing engineering plastic bearing molds, comprising: The processing mechanism 100 includes a base plate 110, a lower mold 120 fixedly installed on the top of the base plate 110, a plurality of guide pillars 130 fixedly installed on the top of the base plate 110, a top plate 140 fixedly installed on the top of the guide pillars 130, a cylinder 150 fixedly installed on the top of the top plate 140, an upper mold 160 fixedly installed at the output end of the cylinder 150 and used in conjunction with the lower mold 120, two connecting plates 170 fixedly installed on the surface of the upper mold 160, and a guide sleeve 180 fixedly installed on the surface of the connecting plate 170 and sleeved on the surface of the guide pillars 130. The timed automatic lubrication mechanism 200 includes a lubrication component 210 for lubricating between the guide post 130 and the guide sleeve 180, and a timer component 220 for controlling the timed automatic lubrication of the lubrication component 210.

[0020] The automatic lubrication of the mold guide post 130 and guide sleeve 180 is achieved through the cooperation between the lubrication component 210 and the timing component 220. This solves the problem of severe wear between the guide post 130 and guide sleeve 180 caused by the lack of automatic lubrication function in traditional bearing processing molds. As a result, the lubrication effect of both is effectively improved, the friction loss between metals is reduced, and the service life of the mold is extended.

[0021] Specifically, the lubrication component 210 includes an oil reservoir 211 fixedly installed on the top of the connecting plate 170, a miniature oil pump 212 fixedly installed on the bottom of the connecting plate 170 for pumping out the lubricant inside the oil reservoir 211, two delivery pipes 213 connected to the output end of the miniature oil pump 212, an annular pipe 214 disposed inside the guide sleeve 180 and connected to the delivery pipes 213, and a number of nozzles 215 disposed on the surface of the annular pipe 214 for spraying the lubricant onto the surface of the guide post 130.

[0022] The oil reservoir 211 is used to store the lubricating fluid.

[0023] Furthermore, the input end of the micro oil pump 212 is connected to a liquid guide pipe, and the other end of the liquid guide pipe is connected to the interior of the oil storage box 211.

[0024] Preferably, the output end of the micro oil pump 212 is connected to two delivery pipes 213 via a tee, and the micro oil pump 212 is fixedly installed at the bottom of the connecting plate 170 via a mounting base.

[0025] Furthermore, the inner side of the guide sleeve 180 is provided with several grooves, and the nozzle 215 is fixedly installed inside the grooves.

[0026] The groove is used to store and install the nozzle 215, so as to prevent the nozzle 215 from interfering with the sliding of the guide sleeve 180 on the surface of the guide post 130.

[0027] Furthermore, the timing component 220 includes a fixed bracket 221 fixedly mounted on the bottom of the connecting plate 170, a gear 222 rotatably mounted on the inner side of the fixed bracket 221 via a rotating shaft, a toothed plate 223 fixedly mounted on the bottom of the top plate 140 and used in conjunction with the gear 222, a transmission cam 224 fixedly mounted on one side of the gear 222 via a rotating shaft, and a time-delay power-off switch 225 fixedly mounted on the top inner side of the fixed bracket 221 and used in conjunction with the transmission cam 224.

[0028] When the upper mold 160 moves upward, the upper mold 160 drives the connecting plate 170 to move upward, and the connecting plate 170 drives the fixing frame 221 to move upward. Then, when the gear 222 moves upward to mesh with the gear plate 223, the gear 222 rotates at a certain angle. Through the rotating shaft gear 222, the transmission cam 224 rotates. When the protrusion of the transmission cam 224 rotates to press the time-delay power-off switch 225, the time-delay power-off switch 225 starts the micro oil pump 212. The micro oil pump 212 will automatically shut off after a preset time, so that the lubricant will automatically lubricate the guide post 130 and the guide sleeve 180 at regular intervals. It should be noted that the above preset time can be flexibly designed according to actual needs.

[0029] Specifically, the toothed plate 223 meshes with the gear 222, and the toothed plate 223 has three protruding teeth on its surface.

[0030] The number of protruding teeth on the surface of gear 222 is a multiple of three, which can be designed according to actual needs. It can be controlled to automatically lubricate after the lower mold 120 and the upper mold 160 are closed a certain number of times.

[0031] Furthermore, the output terminal of the time-delay power-off switch 225 is electrically connected to the input terminal of the micro oil pump 212.

[0032] When the time-delay power-off switch 225 is pressed by the transmission cam 224, the time-delay power-off switch 225 will start the micro oil pump 212, so as to achieve the purpose of starting the micro oil pump 212 at a time.

[0033] When in use, the micro oil pump 212 is started to pump the lubricant inside the oil storage box 211 out through the liquid guide pipe, and then introduce it into the ring pipe 214 inside the guide sleeve 180 through the delivery pipe 213. Under the action of hydraulic pressure, the lubricant is sprayed onto the surface of the guide post 130 through the nozzle 215 to lubricate the guide post 130 and the guide sleeve 180. When the upper mold 160 moves upward, the upper mold 160 drives the connecting plate 170 to move upward, and the connecting plate 170 drives the fixing frame 221 to move upward. Then, when the gear 222 moves upward to mesh with the gear plate 223, the gear 222 rotates at a certain angle. Through the rotating shaft gear 222, the transmission cam 224 rotates. When the protrusion of the transmission cam 224 rotates to press the time-delay power-off switch 225, the time-delay power-off switch 225 starts the micro oil pump 212. The micro oil pump 212 will automatically shut off after a preset time, so that the lubricant will automatically lubricate the guide post 130 and the guide sleeve 180 at regular intervals. In summary, through the cooperation between the lubrication component 210 and the timing component 220, automatic lubrication of the mold guide post 130 and guide sleeve 180 is achieved, which solves the problem of severe wear between the guide post 130 and guide sleeve 180 caused by the lack of automatic lubrication function in traditional bearing processing molds. This effectively improves the lubrication effect of both, reduces frictional loss between metals, and extends the service life of the mold.
