Description

Technical Field

[0001] This utility model belongs to the field of injection molding polishing technology, and specifically relates to an injection molding polishing device. Background Technology

[0002] Injection molded parts are plastic components produced through injection molding and are widely used in various industries, including automotive, electronics, home appliances, and medical fields. The production process of injection molded parts is very delicate, involving multiple stages such as raw material selection, mold design, and injection molding process parameters. After demolding, the surface of injection molded parts often has gate marks, parting lines, or some minor imperfections. To improve the appearance and feel of the product, polishing is usually required.

[0003] Currently, for small injection molded parts, manual polishing is often used. However, manual polishing relies entirely on the experience and skill of the operator. This not only results in slow polishing speed and low production efficiency, but also makes it difficult to ensure that the polishing force and trajectory are completely consistent, which can easily lead to uneven polishing of the product surface, or even localized excessive wear or insufficient polishing. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for injection molded parts, which can automatically and uniformly polish workpieces of different sizes, ensuring that the workpieces achieve the same polishing standard and effect, and guaranteeing the appearance quality and surface flatness of the product.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A polishing device for injection molded parts includes a polishing table. A rotary drive mechanism, an adjustment mechanism, and a workpiece clamping assembly are mounted on the top of the polishing table. The rotary drive mechanism includes a bracket connected to the top of the polishing table. A drive motor is fixedly connected to the outer side of the bracket. The output shaft of the drive motor extends through the inner side of the bracket. A turntable is fixedly connected to the end of the output shaft of the drive motor. A polishing motor is mounted on the inner side of the turntable, and a polishing head is connected to the output shaft of the polishing motor. The adjustment mechanism includes a vertical frame connected to the inner side of the turntable. A sliding block is slidably connected inside the vertical frame. The sliding block is fixedly connected to the polishing motor. A lead screw is connected to the bottom of the inner wall of the vertical frame via a bearing. The top end of the lead screw extends through the top of the vertical frame. The sliding block is threaded onto the surface of the lead screw.

[0007] Preferably, the top of the polishing table is connected to a vertical plate, and an electric telescopic rod is fixedly connected to the outside of the vertical plate. The output end of the electric telescopic rod passes through the vertical plate and is fixedly connected to the clamping assembly.

[0008] Preferably, a guide rod is fixedly connected to the outside of the clamping assembly, and the guide rod is slidably connected to the inside of the upright plate and extends through to the outside of the upright plate.

[0009] Preferably, a support ring is fitted onto the surface of the polishing motor, a vertical groove is provided on one side of the turntable, an auxiliary plate is fixedly connected to the side surface of the support ring, and the auxiliary plate is slidably connected inside the vertical groove.

[0010] Preferably, a dust collection mechanism is provided on the rear side of the polishing table. The dust collection mechanism includes a dust collection box connected to the rear side of the polishing table. A dust collection pipe is connected to the top of the dust collection box. A dust collection hopper is connected to the top of the dust collection pipe. The dust collection hopper is located on the top of the polishing table. A suction fan is connected to the rear side of the polishing table. The output end of the suction fan extends into the interior of the dust collection box. A filter element is connected to the suction end of the suction fan and installed on the inner wall of the dust collection box.

[0011] Preferably, the rear hinge of the dust collection box is connected to a sealing door panel, and the rear side of the sealing door panel is connected to a handle.

[0012] Preferably, the workpiece clamping assembly is one of a three-jaw chuck, an elastic chuck, or a vacuum chuck.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when polishing a workpiece, the workpiece can first be clamped on one side of the workpiece clamping assembly. Then, the drive motor drives the turntable to rotate. The rotation of the turntable will drive the polishing motor and polishing head to rotate, and will polish the surface of the workpiece evenly. During the polishing process, the lead screw can also be rotated. The lead screw can drive the threaded sliding block to slide inside the vertical frame. The sliding block can simultaneously drive and adjust the position of the polishing motor and polishing head, making them deviate from the center of the turntable, expanding the polishing trajectory, avoiding local excessive wear or over-polishing, and helping to evenly distribute the polishing force. Different types of workpieces may require different polishing trajectories. Expanding the trajectory can make the equipment more adaptable to workpieces of various shapes and sizes, improving the flexibility of the system.

[0015] In this invention, a suction fan can be operated during the polishing process. The operation of the suction fan generates suction inside the connected dust collection box. Then, through the connected dust collection pipe and dust collection hopper, the waste generated during the polishing process is filtered by the filter element and collected and sucked into the dust collection box by the suction inside the dust collection box. This prevents waste from accumulating on the surface of the workpiece, affecting the polishing quality, and causing scratches or uneven gloss. The dust collection mechanism can clean and collect waste while processing, ensuring that the surface of the workpiece is clean and improving the polishing effect. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a polishing device for injection molded parts includes a polishing table 1. A rotary drive mechanism, an adjustment mechanism, and a workpiece clamping assembly 4 are mounted on the top of the polishing table 1. The rotary drive mechanism includes a bracket 201 connected to the top of the polishing table 1. A drive motor 202 is fixedly connected to the outside of the bracket 201. The output shaft of the drive motor 202 extends through the inside of the bracket 201. A turntable 203 is fixedly connected to the end of the output shaft of the drive motor 202. A polishing motor 204 is mounted on the inside of the turntable 203. The output shaft of the polishing motor 204 is connected to a polishing head 205. After the workpiece to be polished is clamped inside the workpiece clamping assembly 4, the drive motor 202 can be run to drive the polishing motor 204 and the polishing head 205 to rotate. This allows for polishing of different areas of the workpiece surface, reducing manual operation and avoiding uneven or over-polishing of the workpiece surface.

[0024] The adjustment mechanism includes a vertical frame 301 connected to the inner side of the turntable 203. A sliding block 302 is slidably connected inside the vertical frame 301. The sliding block 302 is fixedly connected to the polishing motor 204. The bottom of the inner wall of the vertical frame 301 is connected to a lead screw 303 through a bearing. The top end of the lead screw 303 extends to the top of the vertical frame 301. The sliding block 302 is threadedly connected to the surface of the lead screw 303. When the turntable 203 drives the polishing motor 204 and the polishing head 205 to rotate, the lead screw 303 can be rotated to drive the sliding block 302 to slide inside the vertical frame 301. This will cause the polishing motor 204 and the polishing head 205 to move and deviate from the center of the turntable 203. Adjusting the movement trajectory of the polishing motor 204 during polishing can adapt to polishing workpieces of different sizes and reduce damage to the workpieces caused by excessive pressure or improper contact during the polishing process.

[0025] like Figure 1 and Figure 3 As shown, the top of the polishing table 1 is connected to a vertical plate 401. An electric telescopic rod 402 is fixedly connected to the outside of the vertical plate 401. The output end of the electric telescopic rod 402 passes through the vertical plate 401 and is fixedly connected to the clamping assembly. Under the operation of the electric telescopic rod 402, it can push or pull the clamping assembly and the workpiece closer to the polishing head 205. The size and shape of the workpiece may be different. The telescopic function of the electric telescopic rod 402 enables the equipment to automatically adjust the position of the clamping assembly according to the needs of different workpieces, ensuring that each workpiece can be polished accurately.

[0026] like Figure 1 and Figure 3 As shown, a guide rod 403 is fixedly connected to the outside of the clamping assembly. The guide rod 403 is slidably connected to the inside of the upright plate 401 and extends to the outside of the upright plate 401. When the workpiece clamping assembly 4 and the workpiece are pushed to translate, the workpiece clamping assembly 4 will drive the guide rod 403 to slide inside the upright plate 401. This can effectively guide the translational movement of the workpiece clamping assembly 4, prevent it from shifting or tilting, help maintain the precise relative position between the workpiece and the polishing head 205, and ensure the uniformity and consistency of the polishing process.

[0027] like Figure 4 As shown, a support ring 501 is fitted onto the surface of the polishing motor 204. A vertical groove 502 is provided on one side of the turntable 203. An auxiliary plate 503 is fixedly connected to the side surface of the support ring 501. The auxiliary plate 503 is slidably connected inside the vertical groove 502. With the cooperation of the support ring 501, the auxiliary plate 503 and the vertical groove 502, the polishing motor 204 can be assisted in its support. At the same time, when adjusting the position of the polishing motor 204, the polishing motor 204 will drive the support ring 501 and the auxiliary plate 503 to slide vertically inside the vertical groove 502, thereby assisting the polishing motor 204 to move smoothly and avoiding deviation due to lack of limit when adjusting the position of the drive motor 202.

[0028] like Figure 1 and Figure 2 As shown, a dust collection mechanism is provided on the rear side of the polishing table 1. The dust collection mechanism includes a dust collection box 601 connected to the rear side of the polishing table 1. A dust collection pipe 602 is connected to the top of the dust collection box 601. A dust collection hopper 603 is connected to the top of the dust collection pipe 602. The dust collection hopper 603 is located on the top of the polishing table 1. A suction fan 604 is connected to the rear side of the polishing table 1. The output end of the suction fan 604 extends into the interior of the dust collection box 601. A filter element 605 is connected to the suction end of the suction fan 604 and installed on the inner wall of the dust collection box 601. The dust collection mechanism can continuously extract dust and waste from the air during the polishing process, keeping the operating environment clean. At the same time, it can effectively suck these wastes into the dust collection box 601, ensuring that the surface of the workpiece can be polished evenly, improving the polishing effect and product quality.

[0029] like Figure 2 As shown, a sealing door 7 is connected to the rear hinge of the dust collection box 601, and a handle is connected to the rear of the sealing door 7. The sealing door 7 ensures that the dust collection box 601 can be sealed during operation to prevent dust leakage and maintain the system's efficient dust collection effect. When it is necessary to clean the waste or dust accumulated in the dust collection box 601, the handle allows operators to quickly open the door for cleaning and maintenance, simplifying the maintenance process of the dust collection box 601 and ensuring that operators can easily remove waste and clean the equipment.

[0030] like Figure 1 and Figure 3 As shown, the workpiece clamping assembly 4 is one of a three-jaw chuck, a flexible chuck, or a vacuum chuck, which can adapt to injection molded parts of different shapes and sizes, providing a flexible clamping method. This allows the workpiece clamping assembly 4 to efficiently handle various types of workpieces, reducing the need for different fixtures and improving the versatility of the production line.

[0031] The working principle of this utility model is as follows: When polishing a workpiece, the workpiece can be clamped on one side of the workpiece clamping assembly 4. Then, the drive motor 202 drives the turntable 203 to rotate. The rotation of the turntable 203 will drive the polishing motor 204 and the polishing head 205 to rotate, and will polish the surface of the workpiece evenly. During the polishing process, the lead screw 303 can also be rotated. The lead screw 303 can drive the threaded sliding block 302 to slide inside the vertical frame 301. The sliding of the sliding block 302 can simultaneously drive and adjust the position of the polishing motor 204 and the polishing head 205, making them deviate from the center of the turntable 203, expanding the polishing trajectory, avoiding local excessive wear or over-polishing, and helping to evenly distribute the polishing force. Different types of workpieces may require different polishing trajectories. Expanding the trajectory can make the equipment more adaptable to workpieces of various shapes and sizes, improving the flexibility of the system.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
