Description

Technical Field

[0001] This utility model relates to the field of hubcap insert production technology, specifically a hubcap insert injection molding device. Background Technology

[0002] Wheel hubcap inserts are metal or high-strength material components pre-installed in the plastic matrix of wheel hubcaps. Their core function is to compensate for the deficiencies of plastic in terms of strength and connectivity, ensuring stable assembly and long-term use of the wheel hubcap. A wheel hubcap insert injection molding device is an injection molding equipment specifically designed for the production of wheel hubcaps (automotive wheel hub decorative covers). Its core function is to precisely embed metal inserts (such as clips and reinforcements) into the plastic matrix during the injection molding process, forming a wheel hubcap product with inserts in one step.

[0003] In existing technologies, traditional wheel hub cover insert injection molding equipment requires the dissolution of plastic granules during injection molding. This equipment cannot process the plastic waste inevitably generated during injection molding, such as gate material, flash, and substandard semi-finished products, into recyclable granules that meet melting requirements on-site. This forces the granule melting process to rely entirely on virgin pure plastic granules, failing to reduce virgin material consumption through the conventional method of "mixing virgin granules with recycled material," and incurring higher pure plastic granule procurement costs. Simultaneously, a large amount of waste is either discarded as industrial waste or requires additional transportation costs to external institutions for processing, further increasing overall production costs. From a production process and stability perspective, if companies choose to purchase third-party recycled plastic granules to supplement the melting process to control costs, the purchased recycled granules may have problems such as uneven particle size and impurities due to the lack of waste pre-processing capabilities in the equipment. Before these substandard recycled rubber particles enter the melting system, additional manual screening and sorting are required, which consumes manpower and time. Even if they enter the system, impurities may not be cleaned properly, causing clumping inside the melting equipment, blockage of the flow channels, and even affecting the molding quality of subsequent injection molded products, indirectly disrupting the stable rhythm of rubber particle melting and overall production. Utility Model Content

[0004] The purpose of this utility model is to provide a wheel hub cover insert injection molding device to solve the problem mentioned in the background art that the lack of a crushing function in the wheel hub cover insert injection molding device leads to increased overall production costs, affects the molding quality of subsequent injection molded products, and indirectly disrupts the melting of rubber particles and the stable rhythm of overall production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hub cap insert injection molding device, comprising an injection molding device body, and further comprising a vibration mounting base fixedly connected to the top of the injection molding device body, an extrusion port disposed on one side of the injection molding device body, a crushing box fixedly connected to the vibration mounting base, a feed port opened on the crushing box, a material dispensing port disposed on the vibration mounting base, a vibration component disposed inside the vibration mounting base, a conveying component disposed inside the injection molding device body, a first motor fixedly connected to one side of the crushing box, a first rotating pulley shaft fixedly connected to the output end of the first motor, a second rotating pulley shaft and a pulley drive shaft rotatably connected inside the crushing box, a drive belt drivingly connecting the second rotating pulley shaft and the pulley drive shaft to the first rotating pulley shaft, a fixed rotating shaft fixedly connected to the pulley drive shaft and the second rotating pulley shaft, and a crushing wheel fixedly connected to the fixed rotating shaft. The first rotating pulley shaft is driven to rotate inside the crushing box by the first motor, and the rotation of the first rotating pulley shaft and the drive belt drives the second rotating pulley shaft and the pulley drive shaft to rotate.

[0006] In the preferred embodiment of this technical solution, there are two fixed rotating shafts, and the two fixed rotating shafts are symmetrically connected to the inside of the crushing box.

[0007] According to the preferred embodiment of this technical solution, the vibration assembly includes a second motor fixedly connected to one side of the vibration mounting base, a rotating connecting shaft fixedly connected to the output end of the second motor, a pushing protrusion fixedly connected to the rotating connecting shaft, a sliding limiting seat slidably connected inside the vibration mounting base, a sliding support plate fixedly connected to the sliding limiting seat, a return spring fixedly connected between the vibration mounting base and the sliding support plate, a vibrating screen disposed inside the sliding support plate, and the sliding support plate slidably connected inside the vibration mounting base.

[0008] In the preferred embodiment of this technical solution, one side of the pushing convex plate is configured as a protrusion, and the protrusion comes into contact with the sliding support plate as the pushing convex plate rotates.

[0009] In the preferred embodiment of this technical solution, two sliding limit seats are provided, and the two sliding limit seats are symmetrically slidably connected inside the vibration mounting base.

[0010] In the preferred embodiment of this technical solution, the vibration mounting base has a groove at the corresponding position of the sliding support plate, and the sliding support plate slides inside the groove.

[0011] According to the preferred embodiment of this technical solution, the conveying component includes a third motor fixedly connected to one side of the injection molding device body, a rotating rod fixedly connected to the output end of the third motor, a stirring paddle fixedly connected to the rotating rod, a material conveying pipe fixedly connected inside the injection molding device body, and a heating body fixedly connected to the material conveying pipe. The third motor drives the rotating rod to rotate inside the injection molding device body, and the rotating rod conveys the plastic particles.

[0012] In this preferred embodiment of the technical solution, two heating bodies are provided, and the two heating bodies are symmetrically arranged on the conveying pipe. Compared with the prior art, the beneficial effects of this utility model are: 1. It can process plastic waste such as gate material and flash on-site. After the waste is fed into the feed port of the crushing box, the first motor drives the first rotating pulley shaft, which in turn drives the second rotating pulley shaft, pulley drive shaft and crushing wheel to rotate, crushing the waste into granules that meet the melting requirements. It realizes the use of "new plastic granules with recycled material", reducing the consumption of new material and the purchase cost of pure plastic granules. At the same time, it avoids the additional costs of waste disposal or external treatment. There is no need to purchase third-party recycled plastic granules, avoiding problems such as uneven particle size and impurities. It saves the manual screening and sorting process, saving manpower and time. Moreover, the crushed recycled granules are more regular, which can reduce the risk of clumping in the melting equipment and blockage of the flow channel, ensure the stable rhythm of plastic granule melting and overall production, and avoid the impact of impurities on the molding quality of injection molded products.

[0013] 2. The second motor drives the rotating connecting shaft, which in turn drives the convex plate to rotate. The convex plate periodically contacts the sliding support plate, and with the elastic reset of the return spring and the limiting position of the sliding limit seat on both sides of the sliding support plate, the sliding support plate, carrying the vibrating screen, vibrates stably back and forth within the groove of the vibrating mounting base. This quickly separates the crushed, qualified recycled particles from the uncrushed large waste and impurities, preventing unqualified materials from entering the subsequent melting process, reducing costs and ensuring stable production. No additional manual sorting of recycled materials is required, saving labor and time costs. Simultaneously, the vibration screening removes impurities, effectively preventing them from causing clumping and blockage of the melting equipment, thus avoiding impacts on the molding quality of injection molded products and ensuring a stable rhythm for particle melting and overall production. Furthermore, the screened unqualified waste can be easily cleaned from the discharge port, further improving the efficiency and cleanliness of the recycled material pretreatment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides an embodiment comprising: an injection molding device body 1, a vibration mounting base 2 fixedly connected to the top of the injection molding device body 1, an extrusion port 3 disposed on one side of the injection molding device body 1, a crushing box 4 fixedly connected to the vibration mounting base 2, a feed port 5 opened on the crushing box 4, a discharge port 6 disposed on the vibration mounting base 2, a vibration assembly disposed inside the vibration mounting base 2, a conveying assembly disposed inside the injection molding device body 1, a first motor 801 fixedly connected to one side of the crushing box 4, a first rotating pulley shaft 802 fixedly connected to the output end of the first motor 801, a second rotating pulley shaft 803 and a pulley drive shaft 804 rotatably connected inside the crushing box 4, and a drive belt 804 drivingly connecting the second rotating pulley shaft 803 and the pulley drive shaft 804 and the first rotating pulley shaft 802. 5. A fixed rotating shaft 806 is fixedly connected to the pulley drive shaft 804 and the second rotating pulley shaft 803. A crushing wheel 807 is fixedly connected to the fixed rotating shaft 806. The first rotating pulley shaft 802 is driven to rotate inside the crushing box 4 by the first motor 801. The rotation of the first rotating pulley shaft 802 and the transmission belt 805 drive the second rotating pulley shaft 803 and the pulley drive shaft 804 to rotate. First, the injection molding raw material is put into the crushing box 4 through the feed port 5. After the first motor 801 is started, it drives the first rotating pulley shaft 802 at the output end to rotate. Through the transmission action of the transmission belt 805, the second rotating pulley shaft 803 and the pulley drive shaft 804 inside the crushing box 4 are driven to rotate simultaneously. This causes the fixed rotating shaft 806 and the crushing wheel 807 fixed on the two shafts to rotate, crushing the raw material.

[0018] Please see Figure 2-3 A further solution based on this embodiment is as follows: two fixed rotating shafts 806 are provided, and the two fixed rotating shafts 806 are symmetrically rotated and connected inside the crushing box 4. By symmetrically rotating and connecting the two fixed rotating shafts 806 inside the crushing box 4, the crushing rollers 807 on each fixed rotating shaft 806 can simultaneously crush the raw material from both sides. This not only expands the crushing coverage of the raw material in the crushing box 4, but also allows the raw material to be subjected to uniform crushing force, avoiding insufficient crushing due to uneven force on the raw material caused by crushing on one side, and ensuring that the lumpy raw material is thoroughly crushed.

[0019] Please see Figure 4 A further embodiment of this solution is as follows: the vibration assembly includes a second motor 808 fixedly connected to one side of the vibration mounting base 2, a rotating connecting shaft 809 fixedly connected to the output end of the second motor 808, a pushing protrusion 810 fixedly connected to the rotating connecting shaft 809, a sliding limiting seat 811 slidably connected inside the vibration mounting base 2, a sliding support plate 812 fixedly connected to the sliding limiting seat 811, a return spring 813 fixedly connected between the vibration mounting base 2 and the sliding support plate 812, and a vibrating screen 814 disposed inside the sliding support plate 812. The sliding support plate 812 is slidably connected inside the vibration mounting base 2. The second motor 808 drives the rotating connecting shaft 809 to drive the pushing protrusion 810 to rotate. With the limiting effect of the sliding limiting seat 811 on the sliding support plate 812 and the elastic return function of the return spring 813, the sliding support plate 812 carrying the vibrating screen 814 can achieve reciprocating sliding vibration inside the vibration mounting base 2.

[0020] Please see Figure 4 A further solution based on this embodiment is as follows: one side of the pushing convex plate 810 is provided with a protrusion, and the protrusion contacts the sliding support plate 812 as the pushing convex plate 810 rotates. By providing a protrusion on one side of the pushing convex plate 810, the protrusion periodically contacts the sliding support plate 812 as the pushing convex plate 810 rotates, which can convert the circular motion of the pushing convex plate 810 into the linear reciprocating motion of the sliding support plate 812. This contact method can not only accurately control the vibration frequency and amplitude of the sliding support plate 812 and avoid the vibration intensity of the vibrating screen 814 from fluctuating due to unstable contact, but also reduce the contact area between the pushing convex plate 810 and the sliding support plate 812, thereby reducing the wear between the two.

[0021] Please see Figure 4A further solution based on this embodiment is as follows: two sliding limit seats 811 are provided, and the two sliding limit seats 811 are symmetrically slidably connected inside the vibration mounting base 2. By symmetrically slidably connecting the two sliding limit seats 811 inside the vibration mounting base 2, the sliding trajectory of the sliding support plate 812 can be limited from both sides, preventing the sliding support plate 812 from shifting or tilting during reciprocating vibration, ensuring that the sliding support plate 812 always slides stably along the preset direction, thereby ensuring the stability of the vibration trajectory of the vibrating screen 814.

[0022] Please see Figure 4 A further solution based on this embodiment is as follows: the vibration mounting base 2 has a groove at the corresponding position of the sliding support plate 812, and the sliding support plate 812 slides inside the groove. By opening a groove on the vibration mounting base 2 at the position corresponding to the sliding support plate 812, the sliding support plate 812 can slide inside the groove, which can provide a clear and stable guide path for the reciprocating motion of the sliding support plate 812, and avoid the sliding support plate 812 from getting stuck or misaligned during the vibration of the vibrating screen 814. At the same time, the groove can also provide a certain support for the sliding support plate 812 and distribute the pressure on the sliding support plate 812.

[0023] Please see Figure 5-6 A further solution based on this embodiment is as follows: The conveying assembly includes a third motor 901 fixedly connected to one side of the injection molding device body 1, a rotating rod 902 fixedly connected to the output end of the third motor 901, a stirring paddle 903 fixedly connected to the rotating rod 902, a material conveying pipe 905 fixedly connected inside the injection molding device body 1, and a heating body 904 fixedly connected to the material conveying pipe 905. The third motor 901 drives the rotating rod 902 to rotate inside the injection molding device body 1, and the rotating rod 902 conveys the plastic particles. The third motor 901 drives the rotating rod 902 to drive the stirring paddle 903 to rotate inside the injection molding device body 1. With the material conveying pipe 905 guiding the plastic particles and the heating body 904 heating and melting the plastic particles, the stirring and heating processes can be completed simultaneously during the conveying of the plastic particles. This ensures that the plastic particles are fully melted and mixed evenly before being conveyed to the extrusion port 3, avoiding quality problems such as bubbles and material shortages in the wheel cover insert after injection molding due to insufficient heating or uneven mixing of the plastic particles.

[0024] Please see Figure 5-6A further solution based on this embodiment is as follows: two heating bodies 904 are provided, and the two heating bodies 904 are symmetrically arranged on the conveying pipe 905. By symmetrically arranging the two heating bodies 904 on the conveying pipe 905, the plastic particles inside can be heated simultaneously from both sides of the conveying pipe 905, so that the plastic particles at different positions in the conveying pipe 905 can absorb heat evenly. This avoids the occurrence of temperature gradients in the conveying pipe 905 due to unilateral heating, which could cause some plastic particles to not melt sufficiently or to be overheated and carbonized. This ensures that the plastic particles always maintain a uniform melting state during the conveying process by the rotating rod 902.

[0025] Working principle: First, the injection molding raw material is fed into the feed port 5 of the crushing box 4. After the first motor 801 starts, it drives the first rotating pulley shaft 802 to rotate. Through the transmission action of the transmission belt 805, it synchronously drives the second rotating pulley shaft 803 and the pulley transmission shaft 804 inside the crushing box 4 to rotate. This causes the two symmetrical fixed rotating shafts 806 and the crushing wheel 807 fixed on the two shafts to rotate, and synchronously crush the raw material from both sides to ensure that the agglomerated raw material is completely crushed. The crushed raw material falls onto the vibrating screen 814 in the vibrating mounting base 2. At this time, the second motor 808 drives the rotating connecting shaft 809 to drive the push plate 810 to rotate. The convex plate on one side of the plate rotates. The block periodically contacts the sliding support plate 812 during rotation. Combined with the limiting action of the two symmetrical sliding limit seats 811 and the elastic reset of the return spring 813, the sliding support plate 812 reciprocates within the groove of the vibrating mounting base 2, causing the vibrating screen 814 to vibrate. This achieves raw material screening. Qualified raw materials pass through the vibrating screen 814 into the injection molding device body 1. The third motor 901 drives the rotating rod 902 and the stirring paddle 903 to rotate, pushing the raw materials to the conveying pipe 905. Two symmetrical heating bodies 904 on the conveying pipe 905 uniformly heat the raw materials, ensuring they are fully melted and mixed. Finally, the mixture is injection molded through the extrusion port 3 to form a hub cap insert. Unqualified raw materials can be removed from the discharge port 6, completing the entire injection molding process.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
