Description

Technical Field

[0001] The utility model relates to the technical field of side mold guide rails, in particular to a side mold guide rail structure with a self-cleaning effect. Background Art

[0002] A guide rail is a groove or ridge made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion. They have a higher rated load than linear bearings and can bear a certain torque. They can achieve high-precision linear motion under high load conditions.

[0003] For example, the public document with application number 202011163470.1 discloses an injection mold guide rail, which rotates the main shaft to make the sliding plate continuously contact the surface of the slide rail. When particles are present, the particles will compress the first spring on the sliding plate, so that the limit plates on both sides pop out to clamp and take the particles away, thereby avoiding sliding on the surface of the slide rail, protecting the anti-oxidation layer from damage, and extending the service life of the slide rail. However, during use, the movement between the slider and the guide rail of this guide rail structure still uses sliding friction. The sliding friction makes the slider fit against the guide rail, generating a large friction resistance, which not only affects the smoothness of the sliding operation, but also causes a certain amount of wear between the slider and the guide rail, which still affects the service life.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a side mold guide rail structure with a self-cleaning effect is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a side mold guide rail structure with a self-cleaning effect to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a side mold guide rail structure with a self-cleaning effect, including a guide rail main body, a slider is slidably arranged inside the groove body of the guide rail main body, and universal ball bearings are symmetrically arranged above the outer surface of the guide rail main body along the left and right sides of the groove body, and protrusions are fixedly installed on the left and right sides below the surface of the slider, and first grooves are opened on the left and right sides of the inner surface of the groove body of the guide rail main body, and circular plates are rotatably arranged on the upper and lower sides of the inner surface of the first groove, and guide rollers are fixedly installed in the middle of the upper and lower opposite sides of the circular plate.

[0007] Preferably, the top of the universal ball is slightly higher than the surface of the guide rail body, the slider is set in a "T" shape, and the vertical rod body of the slider is located inside the guide rail body, and the lower sides of the transverse plate body preferentially contact the universal ball.

[0008] Preferably, the diameter of the circular plate is larger than the diameter of the guide roller, so that a depression is formed in the middle of the circular plate and the guide roller, and the protrusion is located exactly in the depression and fits with the surface of the guide roller.

[0009] Preferably, second grooves are provided on the left and right sides of the inner surface of the groove body of the guide rail body below the first groove, and a cleaning mechanism is provided in the second groove.

[0010] Preferably, the cleaning mechanism includes a connecting rod fixedly mounted on the bottom end of the lower circular plate, and the bottom end of the connecting rod is rotatably connected below the inner surface of the second groove.

[0011] Preferably, the cleaning mechanism also includes a gear fixedly installed on the inner surface of the second groove with a connecting rod, a rack is meshedly arranged on the surface of the gear close to the middle of the guide rail body, a scraper is fixedly installed on the middle of the opposite side of the surface of the rack, and the shape of the scraper is set to be "V" shape.

[0012] Preferably, the scraper is slidably fitted on the lower surface of the groove of the guide rail body, a through cavity is opened in the middle of the bottom end of the inner surface of the groove of the guide rail body, and assembly frames are fixedly installed on both sides of the lower outer surface of the guide rail body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model reduces the friction between the slider and the guide rail body by setting the universal ball, the protrusion, the first groove, the circular plate and the guide roller, and also reduces the wear between the slider and the guide rail body, thereby improving the smoothness of the movement between the slider and the guide rail body, and also extending the service life of the slider and the guide rail body. The depression formed between the circular plate and the guide roller prevents the slider from falling off, and greatly improves the stability of the sliding assembly of the slider and the guide rail body.

[0015] 2. The utility model can automatically scrape and clean the workpiece debris remaining in the guide rail main body groove through the arrangement of the cleaning mechanism, connecting rod, gear, rack and scraper, effectively preventing the debris from accumulating inside the guide rail main body, thereby affecting the normal use of the guide rail main body and the slider;

[0016] 3. The utility model prevents a large amount of debris from accumulating and rising, collapsing into the first groove and the second groove through the arrangement of the through cavity and the assembly frame, and effectively avoids the debris from affecting the normal rotation of the circular plate and the gear. The assembly frame lifts the entire guide rail body to a certain height, that is, a certain gap is reserved for the bottom of the through cavity, which is not only convenient for the subsequent cleaning of the discharged debris, but also prevents the debris from falling and accumulating directly inside the groove formed between the through cavity and the workbench.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2As shown, a side mold guide rail structure with a self-cleaning effect comprises a guide rail body 1, a slider 2 is slidably arranged inside the groove body of the guide rail body 1, universal ball bearings 3 are symmetrically arranged above the outer surface of the guide rail body 1 along the groove body, and protrusions 4 are fixedly installed on the left and right sides below the surface of the slider 2, and first grooves 5 are opened on the left and right sides of the inner surface of the groove body of the guide rail body 1, and circular plates 6 are rotatably arranged on the upper and lower sides of the inner surface of the first groove 5, and guide rollers 7 are fixedly installed in the middle of the upper and lower opposite sides of the circular plate 6, and the upper side of the universal ball bearings 3 is slightly higher than the upper side of the surface of the guide rail body 1, the slider 2 is arranged in a "T" shape, and the vertical rod body of the slider 2 is located inside the guide rail body 1, and the lower sides of the horizontal plate body are preferentially contacted with the universal ball bearings 3, and the diameter of the circular plate 6 is larger than the diameter of the guide roller 7, so that a depression is formed in the middle of the circular plate 6 and the guide roller 7, and the protrusion 4 is just located in the depressed part and fits the surface of the guide roller 7.

[0024] Furthermore, the lower sides of the transverse plate of the slider 2 are in priority contact with the universal ball 3 to avoid serious wear on the overlapping surface of the slider 2 and the guide rail body 1 during the sliding process. At the same time, the universal ball 3 can convert sliding friction into rolling friction to reduce the friction coefficient.

[0025] Furthermore, the guide roller 7 is fixed to the circular plate 6 so that the guide roller 7 can rotate. At this time, the slider 2 moves, and the protrusion 4 contacts the guide roller 7 to convert the sliding friction between the vertical rod body of the slider 2 and both sides of the guide rail body 1 into rolling friction, thereby once again reducing the friction coefficient and the friction loss generated.

[0026] Furthermore, since the diameter of the circular plate 6 is larger than the diameter of the guide roller 7, the protrusion 4 is located inside the recess formed in the middle of the circular plate 6 and the guide roller 7. The upper and lower circular plates 6 will use the upper and lower edges of the protrusion 4 to limit the slider 2, thereby preventing the slider 2 from falling off.

[0027] like Figure 3-Figure 4 As shown, second grooves 8 are provided on the left and right sides of the inner surface of the groove body of the guide rail main body 1 below the first groove 5, and a cleaning mechanism 9 is provided in the second groove 8, and the cleaning mechanism 9 includes a connecting rod 901 fixedly installed on the bottom end of the lower circular plate 6, and the bottom end of the connecting rod 901 is located below the inner surface of the second groove 8 and is rotatably connected, and the cleaning mechanism 9 also includes a gear 902 fixedly installed on the inner surface of the second groove 8 with the connecting rod 901, and a rack 903 is meshedly provided on the surface of the gear 902 close to the middle part of the guide rail main body 1, and a scraper 904 is fixedly installed in the middle part of the opposite side of the surface of the rack 903, and the scraper 904 is slidably fitted on the lower surface of the groove body of the guide rail main body 1, and a through cavity 10 is provided in the middle part of the bottom end of the inner surface of the groove body of the guide rail main body 1, and an assembly frame 11 is fixedly installed on both sides of the left and right sides below the outer surface of the guide rail main body 1.

[0028] Furthermore, the lower circular plate 6 utilizes the connecting rod 901 to drive the gear 902 inside the second groove 8, and the gear 902 engages with the rack 903, so that when the slider 2 moves, the gear 902 engages with the rack 903 to drive the scraper 904 to scrape and clean the workpiece debris inside the guide rail body 1.

[0029] Furthermore, the scraper 904 is shaped as a V-shape placed horizontally, and when the scraper 904 continuously scrapes the debris, the debris will gather and accumulate in the middle of the scraper 904 .

[0030] Furthermore, the through cavity 10 is opened exactly in the middle of the scraper 904, that is, the accumulated debris will fall out of the guide rail body 1 through the through cavity 10, avoiding the situation where the debris continues to accumulate and rise, and collapses into the first groove 5 and the second groove 8.

[0031] Furthermore, the assembly frame 11 lifts the entire guide rail body 1 to a certain height, that is, reserves a certain gap at the bottom of the through cavity 10, which not only facilitates the subsequent cleaning of the discharged debris, but also prevents the debris from falling and accumulating directly inside the groove formed between the through cavity 10 and the workbench.

[0032] Working principle: When using the side mold guide rail structure with self-cleaning effect, first, when the slider 2 is assembled with the guide rail body 1, the upper horizontal plate of the slider 2 contacts the universal ball 3, and the vertical rod contacts the guide roller 7 through the protrusion 4. When the slider 2 moves, the universal ball 3 will rotate, and the protrusion 4 will make the guide roller 7 rotate through the circular plate 6, thereby converting the sliding friction into rolling friction for movement, and during the movement of the slider 2, the circular plate 6 limits the slider 2 up and down through the protrusion 4 to prevent the slider 2 from falling off and deviating. At the same time, when the slider 2 moves, it drives the circular plate 6 to rotate, thereby driving the gear 902 to rotate through the connecting rod 901, and the gear 902 meshes with the rack 903 to move toward the slider. 2 is gradually advanced in the movement direction, so that the scraper 904 slides and advances against the bottom of the inner surface of the groove body of the guide rail body 1, and the workpiece debris remaining in the groove body of the guide rail body 1 is automatically scraped and cleaned. When scraping and pushing the debris, the scraper 904 uses its own V-shaped structure to gather the debris to the middle part. The debris gathered in the middle part will fall and be discharged from the through cavity 10, and the assembly frame 11 lifts the entire guide rail body 1 to a certain height, that is, a certain gap is reserved for the bottom of the through cavity 10, which is not only convenient for the subsequent cleaning of the discharged debris, but also prevents the debris from falling and directly accumulating inside the groove body formed between the through cavity 10 and the workbench. This is the working principle of the side mold guide structure with self-cleaning effect.
