Description

Technical Field

[0001] This application relates to the technical field of injection molding machinery and equipment, and in particular to a wheel injection molding machine. Background Technology

[0002] Automobiles are typically manufactured in modular form, and car wheels are generally produced using injection molding. Injection molding machines are the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds.

[0003] Injection molding machines heat plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity, thus producing car wheels. An injection molding machine includes a machine body, a heating mechanism for melting the plastic, an injection pipe, and a feeding mechanism. During production, the user puts the plastic raw material into the feeding mechanism, which then enters the injection pipe. The injection pipe includes an injection shell and an injection screw rotating inside the injection shell. An injection port is located at the end of the injection shell and connects to the mold cavity. The plastic raw material enters the injection shell through the feeding bin on the machine body. The heating mechanism heats and melts the plastic raw material inside the injection shell, and the injection screw injects the molten plastic into the mold through the injection port. After cooling, it is molded into a car wheel.

[0004] Regarding the aforementioned technologies, after production is completed, it is necessary to remove the plastic residue attached to the inside of the injection molded shell. Since the heating mechanism can directly heat the injection molded shell, the cleaning of the plastic residue inside the injection molded shell is relatively easy. However, after the molten plastic cools down, it will block the injection port. The injection port cannot be directly heated by the heating mechanism, making cleaning more difficult. Special tools are required to disassemble the injection pipe during cleaning, and production needs to be stopped, which is inconvenient for users to clean. Utility Model Content

[0005] To facilitate cleaning of the injection port by users, this application provides a wheel injection molding device.

[0006] The wheel injection molding equipment provided in this application adopts the following technical solution:

[0007] A wheel injection molding machine includes a machine body, a feeding mechanism connected to the machine body, a heating mechanism connected to the machine body, and an injection pipe connected to the interior of the machine body. The injection pipe includes an injection shell fixedly connected to the machine body, an injection auger located inside the injection shell, and a top block fixedly connected to the end of the injection auger. The machine body is provided with a machine head, and the injection auger is connected to the machine head. The machine head drives the injection auger to move along its own axis, and simultaneously drives the injection auger to rotate inside the injection shell. The top block is located at the end of the injection auger away from the machine head, and an injection port is provided at the end of the injection shell away from the machine head. The wheel injection molding machine also includes a drive mechanism connected to the top block and a cleaning mechanism connected to the drive mechanism. The drive mechanism drives the moving end of the cleaning mechanism to move towards or away from the injection port.

[0008] By adopting the above technical solution, when the user needs to clean the plastic residue in the injection port, the drive mechanism is activated to control the cleaning mechanism to move towards the injection port. The cleaning mechanism pushes out the plastic residue in the injection port, eliminating the need for the user to manually remove it with special tools. This reduces the workload of cleaning the plastic residue in the injection port and makes it easier for the user to clean the injection port.

[0009] Optionally, the top block is hollow inside and configured as an installation cavity. A flip cover is provided at the end of the top block away from the machine head. The flip cover is hinged to the main body of the top block and covers the outlet of the installation cavity. The drive mechanism and the cleaning mechanism are both connected inside the installation cavity.

[0010] By adopting the above technical solution, when the user cleans the injection port, the flip cover is opened, allowing the moving end of the cleaning mechanism to extend from inside the mounting cavity to clean the plastic residue in the injection port, thus achieving the cleaning purpose.

[0011] Optionally, the driving mechanism includes a driving gear located inside the mounting cavity, a mounting ring fixedly connected to the top block, and a motor ring rotatably connected to the mounting ring. The driving gear is rotatably connected to the mounting ring, the axis of the driving gear is parallel to the axis of the motor ring, the axis of the motor ring coincides with the axis of the injection molding auger, and an external gear ring is provided on the outer circumference of the motor ring. The driving gear meshes with the external gear ring, and the moving end of the cleaning mechanism is driven and connected to the motor ring.

[0012] By adopting the above technical solution, the mounting ring provides the mounting position and working position for the motor ring and the drive gear. By turning on the drive gear, the motor ring is driven to rotate, thereby driving the moving end of the cleaning structure and cleaning the plastic residue at the injection port.

[0013] Optionally, the mounting ring is provided with a rotating hole, through which the motorized ring passes and is rotatably connected to the inner wall of the rotating hole.

[0014] By adopting the above technical solution, the drive gear is activated, which drives the motor ring to rotate. The rotating hole limits the movement of the motor ring and enables it to rotate stably.

[0015] Optionally, the cleaning mechanism includes a cleaning screw threaded to the motorized ring, the inner wall of the motorized ring being provided with an internal thread, the cleaning screw being threaded to the internal thread of the motorized ring, and the axis of the cleaning screw coinciding with the axis of the motorized ring.

[0016] By adopting the above technical solution, when the motor ring rotates, the cleaning screw moves, which pushes out the plastic residue in the injection port, making it easier for users to clean the injection port.

[0017] Optionally, the cleaning mechanism further includes a support ring fixedly connected inside the mounting cavity. The inner wall of the support ring is provided with an internal thread. The cleaning screw is threaded to the internal thread of the support ring. The axis of the support ring coincides with the axis of the motor ring. The support ring is located on the side of the motor ring closer to the injection port.

[0018] By adopting the above technical solution, the support ring supports the cleaning screw, making the force on the cleaning screw more uniform and enabling the cleaning screw to more stably clean the plastic residue at the injection port.

[0019] Optionally, the end of the cleaning screw away from the machine head is a pointed tip.

[0020] By adopting the above technical solution, the end of the cleaning screw can penetrate into solidified or semi-molten plastic, and when the cleaning screw rotates and moves, it can push the plastic out of the injection port.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The drive mechanism and cleaning mechanism in this application work together. After the cover is opened, the cleaning mechanism pushes out the plastic residue from the injection port under the drive mechanism, thus achieving the purpose of cleaning. This eliminates the need for users to use special cleaning tools, making it easier for users to clean the injection port and improving production efficiency.

[0023] The drive gear, external gear ring, internal thread on the support ring, and internal thread on the motor ring in this application cooperate with each other to drive the cleaning screw and achieve the cleaning purpose. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0029] Currently, in order to facilitate users in cleaning the injection port 411, this application embodiment proposes a wheel injection molding device.

[0030] This application discloses a wheel injection molding equipment. (Refer to...) Figure 1 A wheel injection molding machine includes a machine body 1, a feeding mechanism 2 connected to the machine body 1, a heating mechanism 3 connected to the machine body 1, an injection pipe 4 connected inside the machine body 1, a drive mechanism 5 connected to the injection pipe 4, and a cleaning mechanism 6 connected to the drive mechanism 5. The injection pipe 4 includes an injection housing 41 fixedly connected to the machine body 1, an injection auger 42 located inside the injection housing 41, and a top block 43 fixedly connected to the end of the injection auger 42. The axial direction of the injection auger 42 is parallel to that of the machine body 1. Along its length, the machine body 1 is equipped with a machine head, and an injection auger 42 is connected to the machine head. The machine head drives the injection auger 42 to move along its own axis, and simultaneously drives the injection auger 42 to rotate inside the injection housing 41. A top block 43 is located at the end of the injection auger 42 away from the machine head. An injection port 411 is provided at the end of the injection housing 41 away from the machine head. A drive mechanism 5 is connected to the top block 43, and the drive mechanism 5 drives the moving end of the cleaning mechanism 6 to move towards or away from the injection port 411. The top block 43 is hollow inside and is configured as an installation cavity 431. A flip cover 432 is provided at the end of the top block 43 away from the machine head. The flip cover 432 is hinged to the main body of the top block 43 and covers the outlet of the installation cavity 431. Both the drive mechanism 5 and the cleaning mechanism 6 are connected inside the installation cavity 431.

[0031] When the user needs to clean the plastic residue in the injection port 411, the control flip cover 432 is opened, allowing the moving end of the cleaning mechanism 6 to extend from the mounting cavity 431 to clean the plastic residue in the injection port 411. The drive mechanism 5 is activated to control the cleaning mechanism 6 to move towards the injection port 411. The cleaning mechanism 6 pushes out the plastic residue in the injection port 411, achieving the purpose of cleaning. There is no need for the user to manually remove it with special tools, reducing the workload of cleaning the plastic residue in the injection port 411 and making it easier for the user to clean the injection port 411.

[0032] Reference Figure 2 and Figure 3 The drive mechanism 5 includes a drive gear 51 located inside the mounting cavity 431, a mounting ring 52 fixedly connected to the top block 43, and a motor ring 53 rotatably connected to the mounting ring 52. The axis of the drive gear 51 is parallel to the axis of the injection molding screw 42. The drive gear 51 can be driven by an electric rotating shaft electrically connected to the machine head, or by setting a motor and fixing the output end of the motor coaxially with the shaft of the drive gear 51. In this embodiment, the drive gear 51 is driven by connecting a motor to the rotating shaft of the drive gear 51 to achieve control of the drive gear 51.

[0033] Furthermore, the mounting ring 52 is provided with a rotating hole 521, through which the motorized ring 53 passes and is rotatably connected to the inner wall of the rotating hole 521, thereby achieving the purpose of rotatably connecting the drive gear 51 to the mounting ring 52. The axis of the drive gear 51 is parallel to the axis of the motorized ring 53, and the axis of the motorized ring 53 coincides with the axis of the injection molding screw 42. An external gear ring 531 is provided on the outer circumference of the motorized ring 53, and the drive gear 51 meshes with the external gear ring 531. The moving end of the cleaning mechanism 6 is driven and connected to the motorized ring 53. The mounting ring 52 provides the mounting position and working position for the motorized ring 53 and the drive gear 51. By opening the drive gear 51, the motorized ring 53 is driven to rotate. The rotating hole 521 limits the movement of the motorized ring 53, enabling the motorized ring 53 to rotate stably, thereby driving the moving end of the cleaning structure and cleaning the plastic residue at the injection port 411.

[0034] Reference Figure 2 and Figure 3The cleaning mechanism 6 includes a cleaning screw 61 threadedly connected to a motorized ring 53 and a support ring 62 fixedly connected inside the mounting cavity 431. The inner wall of the motorized ring 53 has internal threads, and the cleaning screw 61 is threadedly connected to these internal threads. The axis of the cleaning screw 61 coincides with the axis of the motorized ring 53. When the motorized ring 53 rotates, the cleaning screw 61 moves, pushing out plastic residue from the injection port 411, facilitating cleaning by the user. The inner wall of the support ring 62 also has internal threads, and the cleaning screw 61 is threadedly connected to these internal threads. The axis of the support ring 62 coincides with the axis of the motorized ring 53, and the support ring 62 is located on the side of the motorized ring 53 closest to the injection port 411. The support ring 62 supports the cleaning screw 61, making the force on the cleaning screw 61 more even and enabling it to more stably clean plastic residue from the injection port 411.

[0035] Furthermore, the end of the cleaning screw 61 furthest from the machine head is a pointed tip. The tip of the cleaning screw 61 can penetrate into solidified or semi-molten plastic. When the cleaning screw 61 rotates and moves, it can insert into the plastic residue and separate the plastic residue from the injection port 411 until the plastic residue is pushed out from the injection port 411, thus completing the cleaning.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
