Description

Technical Field

[0001] This invention belongs to the field of injection molding technology, specifically an injection molding equipment for manufacturing automobile wheel hub covers. Background Technology

[0002] Car wheel covers are an important part of the appearance of vehicle wheels, serving both decorative and protective functions. They are widely used in various passenger and commercial vehicles. Their manufacturing process typically involves injection molding, in which thermoplastic plastic is heated and melted, then injected into a mold cavity, and cooled and solidified to obtain the desired shape. Currently, injection molding equipment for car wheel covers generally includes an injection system, a mold clamping system, a mold, and a cooling and demolding mechanism. During the demolding stage, mechanical ejection or pneumatic-assisted demolding methods are often used to ensure complete demolding of the product.

[0003] However, existing equipment still has shortcomings in the following aspects: for example, the waste generated during the demolding process, such as gate material, flash and other waste, is usually discarded directly, which not only wastes raw materials but also increases production costs. Moreover, this waste is often mixed with good products into the next processing stage, which will also affect product quality and equipment stability.

[0004] Therefore, an injection molding equipment for manufacturing automobile wheel hub covers is proposed to solve the above problems. Summary of the Invention

The material enters the melting mechanism through the material cylinder for heating, and then enters the mold mechanism through the conveying mechanism for injection molding. The mold mechanism is provided with a connected air duct and air passage for rapidly cooling the molding material in the mold mechanism. The equipment also includes a processing component disposed on the main body, which includes a crushing roller, a processing box, and a conveying pipe.

[0007] In the above technical solution, preferably, the processing component includes a processing box and a feeding box, as well as a channel opened on the main body, and the channel is located below the mold mechanism. The processing box is located inside the channel, and the top of the channel penetrates through the main body so that the material falls into the processing box. The processing box includes a material inlet and a transmission box. The crushing roller is located inside the material inlet, and the crushing roller and the transmission box are driven together. When the waste material enters the processing box through the material inlet, it is crushed by the crushing roller and transported to the material cylinder for reuse through the conveying pipe and suction fan set at the tail end of the processing box.

[0008] In the above technical solution, preferably, the crushing rollers are at least two sets, the processing box includes a first partition fixed inside the processing box, as well as a second partition and a third partition, and the two sets of crushing rollers are located between the first partition and the second partition. Each crushing roller includes a plurality of annular arrays of protruding teeth, and a plurality of first partitions are provided between the plurality of protruding teeth, and the protruding teeth and grooves on the two crushing rollers are interleaved.

[0009] In the above technical solution, preferably, a pushing component is provided on the first partition plate. The pushing component includes a baffle and a gear motor.

Supports are fixedly connected to opposite ends of the baffle. A sliding rod is slidably connected within the two supports. A toothed ring is fixedly connected to the sliding rod, and the toothed ring intermittently meshes with the first intermittent gear and the second intermittent gear. A pusher is fixedly connected to one end of the sliding rod, and the pusher faces between the two crushing rollers to push the waste material on the first partition plate into the space between the two crushing rollers.

[0010] In the above technical solution, preferably, a baffle is fixed between the first partition and the top wall of the processing box. The baffle isolates the pusher and the two crushing rollers. The baffle is made of elastic material. The first partition has a movable groove. A connecting rod is fixedly connected to the bottom end of the slide rod. A pusher plate is fixedly connected to the end of the connecting rod away from the slide rod. The pusher plate is located below the two crushing rollers. The second partition has an inclined structure. The lowest end of the second partition is fixedly connected to the third partition. The pusher plate is close to the surface of the second partition. The second partition includes a support plate fixedly connected to the slide rod. Multiple support rods are fixedly connected to the bottom end of the support plate.

[0011] In the above technical solution, preferably, a feeding box is placed on the processing box, and an opening is provided inside the feeding box. The top wall of the processing box is an inclined structure, and the lowest end faces the material inlet. When small waste materials fall onto the processing box through the opening, they can slide into the material inlet for waste processing. A lower opening is provided at one end of the feeding box, and a feeding ladder and a handle are fixedly connected to the lower opening.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a processing component, allows waste materials to be crushed by the crushing rollers inside the processing box and then conveyed back to the material cylinder through the cooperation of the conveying pipe and the suction fan, thereby realizing the recycling of waste materials, reducing raw material waste, and lowering production costs. The interlaced arrangement of the protruding teeth and grooves on the crushing rollers enables the extrusion and cutting of waste materials, especially for the multi-segmentation processing of long waste materials, avoiding jamming problems and improving crushing efficiency and quality.

[0013] 2. By setting up a pushing component, the present invention can automatically push the waste material into the crushing rollers for crushing after the waste material enters the processing box, reducing manual intervention and keeping the waste material in contact with the crushing rollers, which further facilitates the segmentation and crushing and prevents the waste material from slipping between the two crushing rollers and failing to enter smoothly.

[0014] 3. This invention, by incorporating auxiliary components, allows the segmented waste material to be conveyed into a hopper for reuse via a conveying pipe and a suction fan. Multiple sets of fan-shaped crushing blades generate airflow to assist the suction fan, reducing its workload. Furthermore, the waste material undergoes further crushing as it passes through the multiple sets of crushing blades, thereby improving crushing efficiency and preventing waste accumulation at the connection between the conveying pipe and the isolation cover. In summary, this invention reduces raw material waste during production through waste recycling and reuse, aligning with environmental protection principles. It also lowers production costs, improves economic efficiency, and specifically addresses shortcomings in the waste recycling process. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 12As shown, the present invention provides an injection molding equipment for manufacturing automobile wheel hub covers, including a main body 1, a material cylinder 2 and a melting mechanism 3 disposed on the main body 1. The material cylinder 2 and the melting mechanism 3 are connected, and a conveying mechanism is provided between the melting mechanism 3 and the mold mechanism 4. The material enters the melting mechanism 3 through the material cylinder 2 for heating, and then enters the mold mechanism 4 through the conveying mechanism for injection molding. The mold mechanism 4 is provided with a connected air duct 38 and an air passage 39 for rapid cooling of the molding material in the mold mechanism 4. The above structures are all prior art and will not be described in detail below. It also includes a processing component disposed on the main body 1. The processing component includes a crushing roller 13, a processing box 5 and a conveying pipe 31. When waste material enters the processing box 5, it can be crushed and then conveyed back to the material cylinder 2 through the conveying pipe 31.

[0019] The processing assembly includes a processing box 5 and a feeding box 6, as well as a channel opened on the main body 1. The channel is located below the mold mechanism 4, and the processing box 5 is located inside the channel. The top of the channel penetrates the main body 1 so that the material falls into the processing box 5. The processing box 5 includes a material inlet 11 and a transmission box 12. The crushing roller 13 is located inside the material inlet 11, and the crushing roller 13 and the transmission box 12 are driven together. When the waste material enters the processing box 5 through the material inlet 11, it is crushed by the crushing roller 13 and then transported to the material cylinder 2 for reuse through the conveying pipe 31 and the suction fan 32 set at the tail end of the processing box 5.

[0020] The crushing rollers 13 are at least two sets. The processing box 5 includes a first partition 16, a second partition 28, and a third partition 29 fixed inside the processing box 5. The two sets of crushing rollers 13 are located between the first partition 16 and the second partition 28. The two crushing rollers 13 have the same diameter, and each crushing roller 13 includes a plurality of annular arrayed protrusions 15. The sharp ends of the protrusions 15 are blades, which divide the waste material when pressed against them. A plurality of first partitions 16 are provided between the plurality of protrusions 15, and the protrusions 15 and grooves 14 on the two crushing rollers 13 are staggered. The advantage of this arrangement is that when... When the waste material passes between the two crushing rollers 13, the protruding teeth 15 on the two rotating crushing rollers 13 can squeeze and divide the waste material. During this process, some waste material will be squeezed into the groove 14. Since the protruding teeth 15 and the groove 14 are squeezed together, and the groove 14 is also provided with protruding teeth 15, when dividing longer waste material, the longer waste material is squeezed by the protruding teeth 15 in the groove 14, the protruding teeth 15 on the crushing rollers 13, and the two crushing rollers 13 at the same time. This allows the longer material to be divided into multiple segments, thereby improving the crushing efficiency and preventing the problems of long material jamming and limited crushing degree in a single operation.

[0021] A pushing component is provided on the first partition 16, which includes a baffle 18 and a gear motor 19. A first intermittent gear 20 and a second intermittent gear 21 located on opposite sides of the gear motor 19 are rotatably connected to the baffle 18. Supports 24 are fixedly connected to opposite ends of the baffle 18, and slide rods 22 are slidably connected within the two supports 24. A gear ring 23 is fixedly connected to the slide rod 22, and the gear ring 23 intermittently meshes with the first intermittent gear 20 and the second intermittent gear 21. A push head 25 is fixedly connected to one end of the slide rod 22, facing between the two crushing rollers 13, for pushing the waste material on the first partition 16 into the space between the two crushing rollers 13. A baffle 18 is fixedly connected between the first partition 16 and the inner top wall of the processing box 5, isolating the push head 25 and the two crushing rollers 13. The baffle 18 is made of elastic material. The advantage of this arrangement is that the gear motor... When working, the first intermittent gear 20 and the second intermittent gear 21 rotate. Through the alternating engagement of the two intermittent gears with the gear ring 23, the slide bar 22 on the gear ring 23 reciprocates. During this process, the slide bar 22 drives the push head 25 to squeeze the baffle 18, allowing the waste material falling on the first partition 16 to smoothly enter the crushing roller 13 area for segmentation and crushing, preventing the waste material from accumulating on the first partition 16. In addition, the maximum stroke of the push head 25 is close to the surface of the crushing roller 13, and the elastic baffle 18 does not contact the surface of the crushing roller 13. Therefore, when the push head 25 pushes the waste material, the waste material and the crushing roller 13 remain in contact, which further facilitates segmentation and crushing, and prevents the waste material from slipping between the two crushing rollers 13 and failing to enter smoothly. Furthermore, the elastic baffle 18 serves to isolate the waste material, preventing the waste material from falling into the push head 25 and causing problems affecting the transmission structure.

[0022] The first partition 16 has a movable groove 17. A connecting rod 26 is fixedly connected to the bottom end of the slide rod 22. A pusher plate 27 is fixedly connected to the end of the connecting rod 26 away from the slide rod 22. The pusher plate 27 is located below the two crushing rollers 13. The second partition 28 has an inclined structure, and the lowest end of the second partition 28 is fixedly connected to the third partition 29. The pusher plate 27 is close to the surface of the second partition 28. The second partition 28 includes a support plate 36 fixedly connected to the slide rod 22. Multiple support rods 37 are fixedly connected to the bottom end of the support plate 36. The slide rod 22 and the connecting rod 26 are an integral structure. When the slide rod 22 drives the push block 25 to move, it will also drive the connecting rod 26 to move. During this process, the support plate 36 and the support rods 37 on the connecting rod 26 scrape the second partition 28 to prevent the material from accumulating on the second partition 28 and causing blockage. In addition, the spacing of the support rods 37 should be much larger than the size of the waste after division, according to the design of the product waste, to avoid the waste getting stuck between multiple support rods 37 during scraping.

[0023] Since the second partition 28 and the third partition 29 are an integral inclined structure, it is convenient for waste to slide down into the auxiliary components.

[0024] A feeding box 6 is placed on the processing box 5. The feeding box 6 has an opening 10. The top wall of the processing box 5 is inclined, and the lowest end faces the material outlet 11. When small waste materials fall onto the processing box 5 through the opening 10, they can slide into the material outlet 11 for waste processing. One end of the feeding box 6 has a lower opening, and a feeding ladder 7 and a handle 9 are fixedly connected to the lower opening. The bottom of the feeding ladder 7 is equipped with a transfer wheel 8. In the default state, the feeding box 6 is located above the processing box 5. After the workpiece is formed, it falls into the feeding box 6. When cleaning the mold mechanism 4 and the workpiece, the waste on it also falls directly into the feeding box 6. When it is necessary to screen the waste, the feeding box 6 is moved back and forth by the handle 9. During this process, the waste in the feeding box 6 gradually falls onto the inclined top wall of the processing box 5 through the opening 10, and finally slides into the two crushing rollers 13 through the material outlet 11 for division and crushing.

[0025] The processing box 5 is equipped with auxiliary components, including a drive motor 33 and an isolation cover 30 fixedly connected to the second partition 28. The inner end of the isolation cover 30 is connected to the processing box 5, and the outer end of the isolation cover 30 is connected to the conveying pipe 31. A drive rod 34 is fixedly connected to the output end of the drive motor 33, and the drive rod 34 extends into the isolation cover 30. A shredder 35 is fixedly connected to the drive rod 34. By setting up the auxiliary components, the shredded waste is conveyed to the material cylinder 2 through the conveying pipe 31 and the suction fan 32. The material is reused internally. During this process, the drive motor 33 drives multiple sets of crushing blades 35 to rotate via the drive rod 34. Since the shape of the crushing blades 35 is the shape of a fan blade in the prior art, when rotating, the multiple sets of fan blade-shaped crushing blades 35 generate wind force to assist the suction fan 32 in suction work, reducing the workload of the suction fan 32. In addition, the waste can be crushed again when passing through the multiple sets of crushing blades 35, thereby further improving the crushing efficiency and preventing the waste from accumulating at the connection between the conveying pipe 31 and the isolation cover 30.

[0026] It should be noted that the suction fan 32 and the conveying pipe 31 are both existing technologies, therefore, the specific connection methods and other structures will not be described in detail.

[0027] Working principle and usage process of this invention: During operation, the material enters the melting mechanism 3 through the material cylinder 2, where it is heated to a state with good fluidity. Then, it enters the cavity of the mold mechanism 4 through the conveying mechanism for injection molding. At this time, the air duct 38 and air passage 39 in the mold mechanism 4 start to work, and the airflow enters the mold cavity, which on the one hand reduces the temperature of the mold and the product, and on the other hand generates a certain pressure to separate the product from the mold surface, making it easier to demold.

[0028] Waste materials generated during demolding, such as sprue material and flash, fall into the processing box 5 through the channel below the mold mechanism 4. At the same time, waste materials in the loading box 6 can slide down through the opening 10 to the material outlet 11 at one end of the processing box 5.

[0029] After the waste enters the processing box 5, the two sets of crushing rollers 13 cooperate with each other, and the protruding teeth 15 on them squeeze and divide the waste. The pushing components on the first partition 16 include a baffle 18, a gear motor 19, a first intermittent gear 20, a second intermittent gear 21, a slide rod 22, a gear ring 23, and a pusher head 25, which push the waste between the crushing rollers 13 for crushing. The maximum stroke of the pusher head 25 is close to the surface of the crushing roller 13. The elastic baffle 18 prevents the waste from falling into the pusher head 25 and affecting the transmission structure, while isolating the pusher head 25 and the crushing roller 13. The connecting rod 26 at the bottom of the slide rod 22 drives the pusher plate 27 to push the crushed waste to the second partition 28. The second partition 28 has an inclined structure, and its lowest end is fixedly connected to the third partition 29 to facilitate the downward sliding of the waste.

[0030] The waste material slides down to the auxiliary components, which include a drive motor 33 and an isolation cover 30. The drive motor 33 drives the drive rod 34 to rotate, and the crushing blade 35 on the drive rod 34 crushes the waste material a second time. At the same time, it generates wind power to assist the suction fan 32 in working. The suction fan 32 transports the crushed waste material to the material cylinder 2 through the conveying pipe 31, so as to realize the recycling of the waste material.
