Description

Technical Field

[0001] This utility model relates to the field of mudguard mold technology, specifically a mudguard mold. Background Technology

[0002] In the manufacturing of automobiles, motorcycles, and other vehicles, mudguards are crucial components, and their quality and production efficiency significantly impact the overall vehicle performance and manufacturing costs. The primary function of mudguards is to prevent mud, water, and other debris kicked up by the wheels during vehicle operation from splashing onto the vehicle body or other components, thereby protecting the paint and reducing wear and corrosion of parts.

[0003] Traditional mudguard production methods often employ simple molds for manual or semi-automatic production. This approach has several drawbacks. During the material injection stage, the feeding of raw materials is often uneven and unstable, easily leading to uneven density and surface defects in the molded mudguards, affecting product quality. Furthermore, the raw materials are prone to solidification in the hopper due to prolonged standing, increasing waste and impacting subsequent production schedules. In addition, traditional molds are cumbersome and inefficient during demolding, making them unsuitable for large-scale production. Therefore, we propose a new mudguard mold. Utility Model Content

[0004] The purpose of this utility model is to provide a mudguard mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base plate, a lower mold fixedly mounted on the top of the base plate, an upper mold mounted on the top of the lower mold, an mounting frame fixedly mounted on the top of the base plate, several hydraulic rods evenly fixedly mounted on the top of the mounting frame, a lifting plate fixedly mounted at the end of the telescopic arm at the bottom of the hydraulic rods, several fixing rods evenly fixedly mounted on the bottom of the lifting plate, the bottom ends of the fixing rods fixedly connected to the top of the upper mold, a material box fixedly mounted on the lifting plate, a discharge pipe fixedly mounted on the bottom of the material box, a discharge port fixedly mounted on the discharge pipe, the discharge port fixedly connected to the injection port on the upper mold, a detachable cover plate on the top of the material box, a stirring shaft rotatably mounted on the cover plate, several stirring rods evenly fixedly mounted on the stirring shaft, stirring blades fixedly mounted at the bottom of the stirring shaft, several mounting rods evenly fixedly mounted on the stirring shaft, and scrapers fixedly mounted on the outer ends of the mounting rods via a reset mechanism, the scrapers contacting the inner wall of the material box.

[0006] Preferably, the reset mechanism includes a movable rod fixedly installed at the outer end of the mounting rod, a limiting plate fixedly installed at the outer end of the movable rod, an mounting sleeve slidably disposed on the outer side of the limiting plate, the outer end of the mounting sleeve being fixedly connected to a scraper, and a reset spring also being disposed inside the mounting sleeve, one end of the reset spring being fixedly connected to the limiting plate, and the other end of the reset spring being fixedly connected to the inner wall of the mounting sleeve.

[0019] This utility model provides a technical solution: such as Figures 1-4 The mudguard mold shown includes a base plate 1, a lower mold 2 fixedly installed on the top of the base plate 1, an upper mold 3 set on the top of the lower mold 2, an installation frame 4 fixedly installed on the top of the base plate 1, a plurality of hydraulic rods 6 evenly fixedly installed on the top of the installation frame 4, a lifting plate 5 fixedly installed at the end of the telescopic arm at the bottom of the hydraulic rods 6, a plurality of fixing rods 7 evenly fixedly installed at the bottom of the lifting plate 5, and the bottom ends of the fixing rods 7 fixedly connected to the top of the upper mold 3.

An auger conveyor plate 16 is rotatably installed inside the discharge pipe. A discharge port 17 is also fixedly installed on the discharge pipe. The discharge port 17 is fixedly connected to the injection port on the upper mold 3. At this time, under the action of the auger conveyor plate 16 and the discharge port 17, the raw material in the material box 8 can be quickly introduced into the upper mold 3, thereby realizing the molding of the mudguard. A drive motor 18 is also fixedly installed at the bottom of the discharge pipe. The power output shaft of the drive motor 18 is fixedly connected to the rotating shaft of the auger conveyor plate 16 through a coupling. At this time, the drive motor 18 can drive the auger conveyor plate 16 to rotate.

[0021] The top of the material bin 8 is detachably equipped with a cover plate 9, on which a stirring shaft 12 is rotatably mounted. Several stirring rods 13 are evenly fixedly installed on the stirring shaft 12. Under the action of the stirring rods 13, the raw materials in the material bin 8 can be stirred, thereby reducing the possibility of solidification and affecting subsequent use. Stirring blades 14 are also fixedly installed at the bottom of the stirring shaft 12. Under the action of the stirring blades 14, the raw materials can be further stirred. The cover plate 9 is also provided with a feed inlet 10, under the action of the feed inlet 10, the raw materials can be added into the material bin 8.

[0022] Several mounting rods 15 are evenly fixedly installed on the stirring shaft 12. A scraper 19 is fixedly installed on the outer end of the mounting rod 15 through a reset mechanism. The scraper 19 contacts the inner wall of the material box 8. At this time, the scraper 19 can scrape off the raw material adhering to the inner wall of the material box 8, thereby ensuring the efficiency of the material box 8.

[0023] The reset mechanism includes a movable rod 20 fixedly installed at the outer end of the mounting rod 15. A limiting plate 21 is fixedly installed at the outer end of the movable rod 20. A mounting sleeve is slidably mounted on the outer side of the limiting plate 21. The outer end of the mounting sleeve is fixedly connected to the scraper 19. A reset spring 22 is also provided inside the mounting sleeve. One end of the reset spring 22 is fixedly connected to the limiting plate 21, and the other end of the reset spring 22 is fixedly connected to the inner wall of the mounting sleeve. Under the action of the reset spring 22, the scraper 19 can always be in contact with the inner wall of the material box 8, thereby ensuring the scraping quality of the scraper 19 for the attached raw material.

[0024] A mounting shell 11 is also fixedly installed on the top of the cover plate 9. A drive shaft 25 is rotatably mounted inside the mounting shell 11 via bearings. A first bevel gear 23 is connected to the drive shaft 25 via a key. A stirring shaft 12 passes through the bottom wall of the mounting shell 11 and extends into the interior of the mounting shell 11. A second bevel gear 24 is connected to the stirring shaft 12 via a key inside the mounting shell 11. The second bevel gear 24 meshes with the first bevel gear 23. At this time, rotating the drive shaft 25 can drive the stirring shaft 12 to rotate through the first bevel gear 23 and the second bevel gear 24. A servo motor 26 is also fixedly installed on the outer wall of the mounting shell 11. The power output shaft of the servo motor 26 is fixedly connected to the drive shaft 25 via a coupling. At this time, the servo motor 26 can drive the first bevel gear 23 to rotate.

[0025] Working principle: Raw materials for making mudguards are added to the material box 8 through the feed inlet 10 on the cover plate 9. Then, the servo motor 26 on the outer wall of the mounting shell 11 is started, and its power output shaft drives the drive shaft 25 to rotate. The first bevel gear 23 on the drive shaft 25 rotates accordingly. Since the first bevel gear 23 meshes with the second bevel gear 24 on the stirring shaft 12, it drives the stirring shaft 12 to rotate. The stirring rod 13 and stirring blade 14 on the stirring shaft 12 stir the raw materials in the material box 8 to prevent solidification. At the same time, the stirring shaft 12 drives the mounting rod 15 to rotate. The scraper 19, connected to the outer end of the mounting rod 15 through a reset mechanism, contacts the inner wall of the material box 8. Under the action of the reset spring 22, the limiting plate 21 pushes the mounting sleeve, keeping the scraper 19 in close contact with the inner wall of the material box 8, scraping away the raw materials adhering to the inner wall.

[0026] When material injection is required, the drive motor 18 at the bottom of the discharge pipe is started. Its power output shaft drives the auger conveyor 16 to rotate, conveying the raw material in the material box 8 through the discharge pipe and unloading port 17 to the injection port of the upper mold 3, thus realizing material injection. After material injection is completed, the hydraulic rod 6 at the top of the mounting frame 4 is activated. Its telescopic arm drives the lifting plate 5 to descend. The lifting plate 5 drives the upper mold 3 to descend through the fixing rod 7, closing with the lower mold 2 to perform the molding of the mudguard. After molding is completed, the hydraulic rod 6 drives the lifting plate 5 to rise, which in turn drives the upper mold 3 to rise, completing the demolding process.
