Description

Technical Field

[0001] This utility model relates to the technical field of plastic toy processing equipment, and in particular to a CNC grinding device for plastic toys. Background Technology

[0002] Plastic toys are mainly made of high molecular synthetic resins, such as polyvinyl chloride and polyethylene, as the main raw materials, and then plasticizers, stabilizers and other auxiliary materials are added. The basic high molecular materials can have plasticity and fluidity under specific temperature and pressure, and can maintain a fixed shape after being molded by plastic molds.

[0003] The manufacturing processes for plastic toys include injection molding, blow molding, rotational molding, PVC soft molding, and inflatable molding. Taking injection molding as an example, the general process involves using an injection unit to inject molten resin material into a closed mold, followed by cooling, pressure holding, and demolding. This process is highly efficient and allows for mass production; therefore, injection molding is currently the most commonly used plastic toy manufacturing process.

[0004] Based on this, Chinese patent document CN219789101U discloses a plastic toy injection molding device, which includes a male mold plate and a female mold plate. An upper fixing plate is fixedly installed on the top of the female mold plate, and a sprue sleeve is fixedly installed at the center of the upper fixing plate. The bottom of the female mold plate has symmetrically opened upper cavities, and a first runner is opened on one side of the middle of the upper cavity. The top of the male mold plate has symmetrically opened lower cavities. This utility model sets a first movable column and a second movable column, and sets a limiting block in the upper cavity. The limiting block and the limiting groove restrict the stability of the core and prevent it from shifting. An installation frame is provided, and the core is installed by a snap-fit ​​mechanism, which facilitates installation and disassembly, making it easy to replace in case of problems, and also enhances the stability of the core installation.

[0005] However, the aforementioned injection molding apparatus for plastic toys still has technical problems in completely eliminating molding defects in plastic toy products. Specifically, during the injection molding process of plastic toys, surface defects such as burrs, parting lines, and flash are easily generated. These surface defects caused by molding defects usually need to be removed through a grinding process to avoid affecting the assembly accuracy of plastic toys or causing safety hazards such as sharp edges. For example, if there are burrs in the gear transmission parts of toys, it may cause movement jamming or even damage to the internal structure. In addition, children's toys have strict requirements for edge smoothness. The grinding process can reduce the sharp angle to below 0.3mm to meet the GB 6675 standard, thereby preventing children's skin from being scratched. Moreover, mirror-polishing of accessible surfaces can reduce the risk of microbial adhesion. Furthermore, the smooth surface after grinding can improve the uniformity of spraying by more than 30%, avoiding color difference or coating peeling. The ink adhesion in the printing process is improved by 50%, ensuring that the pattern is clear and durable. For example, the gradient color process of blind box toys usually requires a flawless substrate. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Please refer to the following: Figures 1 to 3 This utility model discloses a CNC grinding device for plastic toys, comprising: a base 1, a stand 2, a longitudinal drive mechanism 3, a transverse drive mechanism 4, and a grinding execution mechanism 5; the stand 2 is disposed on the base 1, the longitudinal drive mechanism 3 is disposed on the side of the stand 2, the transverse drive mechanism 4 is disposed on the side of the longitudinal drive mechanism 3, and the longitudinal drive mechanism 3 and the transverse drive mechanism 4 are drivenly connected; the grinding execution mechanism 5 is disposed on the side of the transverse drive mechanism 4, and the transverse drive mechanism 4 and the grinding execution mechanism 5 are drivenly connected.

[0029] Specifically, when the CNC polishing device for plastic toys according to this invention is in operation, an external control terminal, such as an industrial computer or other industrial computer device, can output control signals to the longitudinal drive mechanism 3, the transverse drive mechanism 4, and the polishing execution mechanism 5 respectively. When the plastic toy product that has completed injection molding is fixed in a preset installation position, the external control terminal first sends a start command to the longitudinal drive mechanism 3 and the transverse drive mechanism 4 according to the preset polishing process, so that the longitudinal drive mechanism 3 lowers the transverse drive mechanism 4 to a preset height position, and then the transverse drive mechanism 4 drives the polishing execution mechanism 5 to move to the position of the plastic surface to be polished. At this time, the polishing execution mechanism 5 starts the polishing action, and thus, under the joint action of the longitudinal drive mechanism 3 and the transverse drive mechanism 4, the polishing operation continues to be performed on different positions of the plastic toy until the surface of the plastic toy is polished to a preset smoothness. After that, the longitudinal drive mechanism 3 and the transverse drive mechanism 4 are reset under the control of the external control terminal to wait for the next polishing process. Therefore, the CNC grinding device for plastic toys of this utility model can automatically grind and polish the molded plastic toys, so that the surface of the plastic toys can be free of molding defects such as burrs, parting lines and flash. Thus, the CNC grinding device for plastic toys of this utility model solves the technical problem of how to improve the molding defects of plastic toys in the injection molding process.

[0030] Furthermore, the longitudinal drive mechanism 3 includes a longitudinal rodless cylinder 301, a longitudinal piston moving block 302, a longitudinal support frame 303, a longitudinal guide rail 304, and a longitudinal sliding block 305. The longitudinal rodless cylinder 301 is disposed on the side of the upright 2, and the longitudinal rodless cylinder 301 is drivenly connected to the longitudinal piston moving block 302. The longitudinal piston moving block 302 is connected to the middle of the longitudinal support frame 303. The two longitudinal guide rails 304 are respectively disposed opposite to each other on both sides of the longitudinal rodless cylinder 301. Each longitudinal guide rail 304 is disposed on the side of the upright 2, and a longitudinal sliding block 305 is correspondingly and movably connected to each longitudinal guide rail 304. Each longitudinal sliding block 305 is connected to the longitudinal support frame 303.

[0031] Furthermore, the transverse drive mechanism 4 includes a transverse rodless cylinder 401, a transverse piston moving block 402, a transverse support frame 403, a transverse guide rail 404, and a transverse sliding block 405. The transverse rodless cylinder 401 is disposed on the side of the longitudinal support frame 303, and the transverse rodless cylinder 401 is drivenly connected to the transverse piston moving block 402. The transverse piston moving block 402 is connected to the middle of the transverse support frame 403. The two transverse guide rails 404 are respectively disposed opposite to each other on both sides of the transverse rodless cylinder 401.

Each transverse sliding block 405 is connected to the transverse support frame 403.

[0032] Furthermore, the grinding actuator 5 includes a hanger 501, a grinding drive motor 502, a rotating spindle 503, and a grinding head 504; the hanger 501 is disposed on the side of the transverse support frame 403, the grinding drive motor 502 is disposed in the hanger 501, the grinding drive motor 502 is drivenly connected to the rotating spindle 503, and the grinding head 504 is disposed at one end of the rotating spindle 503.

[0033] Specifically, when the longitudinal rodless cylinder 301 is activated, it can drive the longitudinal piston moving block 302 to reciprocate downward or upward along the longitudinal direction. Thus, the longitudinal piston moving block 302 drives the longitudinal support frame 303 to reciprocate downward or upward. When the longitudinal support frame 303 moves, the longitudinal sliding block 305 can be simultaneously driven to reciprocate along the limit of the longitudinal guide rail 304, thereby making the movement of the longitudinal support block 303 smoother.

[0034] Specifically, when the transverse rodless cylinder 401 is activated, it can drive the transverse piston moving block 402 to move back and forth laterally, thereby driving the transverse support frame 403 to move back and forth laterally. When the transverse support frame 403 moves back and forth, the transverse sliding block 405 can follow it and move back and forth along the limit of the transverse guide rail 404, thereby making the movement of the transverse support frame 403 more stable.

[0035] Furthermore, when the longitudinal drive mechanism 3 and the transverse drive mechanism 4 work together to drive the grinding execution structure 5 to a preset position, the grinding drive motor 502 can drive the rotating spindle 503 to rotate, thereby driving the grinding head 504 to rotate, so that the grinding head 504 can perform grinding, polishing and other processing operations on the preset position.
