Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, and in particular to a self-lubricating guide plate and guide sleeve for automotive molds. Background Technology

[0002] Guide bushings are standard components installed on molds to ensure the guiding accuracy of the mold during mold closing and to withstand lateral pressure, while also preventing damage from direct collisions. Guide pillars are generally installed on the moving mold, while guide bushings are installed on the fixed mold. When the mold is not closed, there is a certain gap between the guide pillars and guide bushings to facilitate mold assembly.

[0003] For example, Chinese Patent Publication No. CN219522762U discloses a novel mold guide sleeve, including a guide sleeve body and grooves; the grooves are formed on the outer surface of the guide sleeve body, and the guide sleeve body is cylindrical in structure, and there are three grooves; it also includes: a heat dissipation plate, fixed around the inside of the groove, and the height of the heat dissipation plate is the height of the groove, and the width of the heat dissipation plate is less than the depth of the groove; heat dissipation holes are evenly distributed on the outer surface of the guide sleeve body, and the depth of the heat dissipation holes is less than the distance from the groove to the inner side of the guide sleeve body; grooves are formed at equal intervals on the inner surface of the guide sleeve body, and the grooves are filled with lubricant to reduce friction between workpieces; and a support plate is set inside the guide sleeve body.

[0004] However, in the existing technology, during multiple mold closing processes, the guide pillar will also slide relative to the guide sleeve. During this process, the guide pillar and the guide sleeve will be in close contact, which will cause the temperature to rise due to friction. If the expansion coefficients of the two are different, the gap between them will change. Moreover, the temperature rise will cause the viscosity of the lubricating oil or grease between the guide sleeve and the guide pillar to decrease, resulting in a decrease in lubrication performance. This will increase the frictional resistance between the guide sleeve and the guide pillar, accelerate wear, and even cause the guide pillar to jam or slide poorly. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the viscosity of the lubricating oil or grease between the guide sleeve and the guide post decreases due to temperature rise, resulting in a decline in lubrication performance. Therefore, this invention proposes a self-lubricating guide plate and guide sleeve for automotive molds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-lubricating guide plate and guide sleeve for automotive molds, comprising a guide post and a guide sleeve body, wherein the guide post is slidably connected to the guide sleeve body, a top plate is fixedly connected to the top of the guide sleeve body, and a bottom plate is fixedly connected to the bottom of the guide sleeve body, wherein multiple flow grooves are provided inside the guide sleeve body, the multiple flow grooves are vertically distributed on the inner wall of the guide sleeve body, an insertion groove is provided in the middle of the outer side of the guide sleeve body, and two sliding grooves are provided on the outer side of the guide sleeve body, the two sliding grooves being symmetrically distributed on the outer wall of the guide sleeve body with the insertion groove as the center.

[0007] Preferably, a heat-conducting sleeve is fitted onto the middle of the outer wall of the guide sleeve body, and a connecting block is fixedly connected to the center of the inner wall of the heat-conducting sleeve.

[0008] Preferably, the inner wall of the heat-conducting sleeve is fixedly connected to two sliding strips, which are symmetrically distributed on the inner wall of the heat-conducting sleeve with the connecting block as the center.

[0009] Preferably, the connecting block is engaged with the insertion slot, and the sliding strip is slidably connected to the sliding slot.

[0010] Preferably, a lubrication groove is formed in the center of the top of the top plate, and a flow groove is formed on the surface of the lubrication groove.

[0011] Preferably, the flow channel is connected to one of the heat dissipation channels.

[0012] Preferably, the guide sleeve body has an overflow groove inside, and the two ends of the overflow groove are respectively connected to the sliding groove and the heat dissipation groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the lubrication effect can be improved by the synergistic effect of the lubrication groove and the heat dissipation groove. The heat dissipation groove design inside the guide sleeve body effectively prevents problems caused by heat accumulation. By expanding the heat dissipation space, the heat dissipation groove can quickly dissipate the heat generated by friction between the guide post and the guide sleeve during multiple mold closing processes.

[0015] 2. In this utility model, through the precise cooperation between the guide post and the guide sleeve body, the guiding accuracy of the automobile mold during the mold closing process is significantly improved, ensuring the stability and precision of the mold. The lubricating oil can circulate through the design of the flow groove and overflow groove, which not only plays a lubricating role, but also dissipates heat and avoids gap changes and lubricating oil viscosity reduction caused by material expansion.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figure 1-4 As shown, this utility model provides a self-lubricating guide plate and guide sleeve for automotive molds, including a guide post 1 and a guide sleeve body 3. The guide post 1 and the guide sleeve body 3 are slidably connected. A top plate 37 is fixedly connected to the top of the guide sleeve body 3, and a bottom plate 31 is fixedly connected to the bottom of the guide sleeve body 3. Multiple flow grooves 321 are opened inside the guide sleeve body 3. The multiple flow grooves 321 are vertically distributed on the inner wall of the guide sleeve body 3. An insertion groove 35 is opened in the middle of the outer side of the guide sleeve body 3, and two sliding grooves 34 are opened on the outer side of the guide sleeve body 3. The two sliding grooves 34 are symmetrically distributed on the outer wall of the guide sleeve body 3 with the insertion groove 35 as the center.

[0025] The specific settings and functions of this embodiment will be described in detail below. When the mold is closed, the guide post 1 will be precisely inserted into the interior of the guide sleeve body 3. This fit design not only ensures the guiding accuracy of the mold during mold closing, but also withstands pressure from the sides, preventing misalignment or collision of the mold during operation. Through the tight fit between the guide post 1 and the guide sleeve, the stability of the mold during the opening and closing process is significantly improved, thereby ensuring product quality and production efficiency.

[0026] To further enhance the performance and lifespan of the guide pillar 1 and guide sleeve, heat dissipation grooves 33 are designed inside the guide sleeve body 3. These grooves 33 not only ensure the stability of the insertion of the guide pillar 1 and guide sleeve but also increase the heat dissipation space of the guide sleeve. During multiple mold closing processes, friction generates heat. If this heat cannot be dissipated in time, the temperature of the guide pillar 1 and guide sleeve will rise, leading to material expansion and changes in clearance. In addition, high temperatures can affect the viscosity of the lubricating oil, reducing lubrication effectiveness and increasing wear. The heat dissipation grooves 33 effectively dissipate the generated heat quickly, keeping the guide pillar 1 and guide sleeve within a suitable operating temperature range, thereby extending the service life of the mold and ensuring continuous production.

[0027] Example 2

[0028] like Figure 3 and Figure 4 As shown, a heat-conducting sleeve 2 is fitted onto the middle of the outer wall of the guide sleeve body 3, and a connecting block 22 is fixedly connected to the center of the inner wall of the heat-conducting sleeve 2. Two sliding strips 21 are fixedly connected to the inner wall of the heat-conducting sleeve 2, and the two sliding strips 21 are symmetrically distributed on the inner wall of the heat-conducting sleeve 2 with the connecting block 22 as the center. The connecting block 22 is engaged with the insertion slot 35, and the sliding strips 21 are slidably connected with the sliding groove 34. A lubrication groove 32 is provided in the center of the top of the top plate 37, and a flow groove 321 is provided on the surface of the lubrication groove 32. The flow groove 321 communicates with one of the heat dissipation grooves 33. An overflow groove 36 is provided inside the guide sleeve body 3, and the two ends of the overflow groove 36 are respectively connected to the sliding groove 34 and the heat dissipation groove 33.

[0029] The overall effect of this embodiment is that the design of the lubrication groove 32 cleverly introduces lubricating oil into the guide sleeve body 3. When lubricating oil is added to the lubrication groove 32, it flows evenly into each heat dissipation groove 33 through the flow groove 321. As the guide post 1 is continuously inserted and withdrawn from the guide sleeve body 3, excess lubricating oil is carried by the guide post 1 to other heat dissipation grooves 33, ensuring that the entire interior of the guide sleeve body 3 is adequately lubricated.

[0030] This lubrication design not only reduces friction between the guide post 1 and the guide sleeve body 3, but also prevents the accumulation of heat generated by friction. At the same time, the presence of lubricating oil can also play a certain buffering role, reducing damage to the mold caused by impact and vibration.

[0031] Besides lubrication, the heat dissipation grooves 33 also play a crucial role in heat dissipation. The uppermost and lowermost heat dissipation grooves 33 of the guide sleeve body 3 are connected to the sliding groove 34 via the overflow groove 36. This means that when lubricating oil flows into these grooves, it will further flow into the sliding groove 34. The sliding groove 34 is in close contact with the sliding strip 21 on the inner wall of the heat-conducting sleeve 2. Through this contact, the lubricating oil can effectively transfer heat to the heat-conducting sleeve 2, thereby achieving heat dissipation.

[0032] The overflow groove 36 is designed with a certain tilt angle. This tilt design ensures that when the guide post 1 leaves the inside of the guide sleeve body 3, the lubricating oil can flow smoothly from the sliding groove 34 back into the heat dissipation groove 33. This return mechanism not only ensures the circulation of lubricating oil, but also avoids problems such as poor heat dissipation or insufficient lubrication caused by lubricating oil retention.

[0033] The device's operation and working principle are as follows: When the mold is closed, the guide post 1 is precisely inserted into the guide sleeve body 3. This precise fit between the guide post 1 and the guide sleeve body 3 significantly improves the guiding accuracy of the automotive mold during the mold closing process.

[0034] The heat dissipation grooves 33 designed inside the guide sleeve body 3 not only ensure the stability of the insertion between the guide post 1 and the guide sleeve body 3, but also expand the heat dissipation space of the guide sleeve body 3. This effectively prevents the temperature from rising due to heat generated by friction after multiple mold closings of the guide post 1 and the guide sleeve body 3, thereby avoiding gap changes caused by material expansion and the problem of reduced lubricant viscosity. For effective lubrication, the lubrication groove 32 is used to add lubricating oil. The lubricating oil is guided into the heat dissipation groove 33 through the flow groove 321. Whenever the guide post 1 enters the guide sleeve body 3, excess lubricating oil is carried by the guide post 1 to other heat dissipation grooves 33. The uppermost and lowermost heat dissipation grooves 33 of the guide sleeve body 3 are connected to the sliding groove 34 through the overflow groove 36. This allows the lubricating oil to flow into the sliding groove 34, and then achieve the heat dissipation effect of the lubricating oil by contacting the sliding strip 21 on the inner wall of the heat-conducting sleeve 2.

[0035] Furthermore, because the overflow groove 36 is designed with an inclined angle, when the guide post 1 exits from inside the guide sleeve body 3, the lubricating oil can flow back from the sliding groove 34 to the heat dissipation groove 33 by means of this inclined angle. This design ingeniously completes the operation cycle of lubrication and heat dissipation.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
