The grinding head 107 is snapped into the front side of the grinder 106.

[0030] In this embodiment: By setting up the grinding component 1, the grinding component 1 can achieve the effect of all-round grinding treatment on one side of the injection-molded plastic part, thus eliminating the need to transfer the injection-molded plastic part to the grinding area after injection molding, thereby speeding up work efficiency. At the same time, mechanical control is more precise than manual control. By setting up the adjustment component 2, the adjustment component 2 can facilitate the replacement of mold 8 and module 9. At the same time, the adjustment component 2 can also rotate and adjust the injection-molded plastic part, thus achieving the effect of all-round grinding treatment on the surface of the plastic part in conjunction with the grinding component 1. By setting up the electric telescopic plate 101, the electric telescopic plate 101 can connect to the adjustment plate 102 for lifting and lowering adjustment. The effect of the joint is achieved through the setting of the adjustment plate 102, which has a built-in guide rail. The guide rail is connected to the transmission belt 103, thereby driving the transmission belt 103 to rotate. This allows the transmission belt 103 to achieve the effect of left and right adjustment of the connecting block 104. The connecting block 104 can also connect to the electric telescopic column 105. The electric telescopic column 105 can then connect to the grinding machine 106 for front and back adjustment. The grinding machine 106 is an existing device.

[0034] In this embodiment: the connecting frame 201 connects and fixes the module 9, while the limiting plate 202 slides and limits the connecting frame 201. Fixing holes are provided on the front sides of the connecting frame 201 and the limiting plate 202 for fixing with bolts. The connecting frame 201 and the limiting plate 202 are also provided on the top of the mold 8. Both the connecting frame 201 and the limiting plate 202 have injection holes at their tops. The limiting ring 203 limits the connection seat 204. The rotating connection works as follows: The rotating rod 205 connects and fixes the limiting plate 202, thus, in conjunction with the rotational power provided by the first motor 206, it drives the limiting plate 202 to rotate and adjust. The rotating plate 207 connects to the connecting seat 204. The adjusting rod 208 fixes the rotating plate 207, thus, in conjunction with the rotational power provided by the second motor 209, it causes the rotating plate 207 to drive the connecting seat 204 to rotate and adjust.

[0035] Specifically, such as Figure 5 As shown, a groove 10 is provided on the front side of the first support plate 4, and the inner wall of the groove 10 is slidably connected to the surface of the adjustment plate 102.

[0036] Specifically, such as Figure 5 As shown, a fixing groove 11 is provided at the bottom of the slide 10, and the inner wall of the fixing groove 11 is fixedly connected to the surface of the electric telescopic plate 101.

[0037] In this embodiment: by setting the sliding groove 10, the sliding groove 10 can achieve the effect of limiting the sliding connection of the adjusting plate 102; by setting the fixing groove 11, the fixing groove 11 can achieve the effect of connecting and fixing the electric telescopic plate 101.

[0038] Specifically, such as Figure 5 As shown, the top and bottom of the connecting block 104 are fixedly connected to the limiting block 12, and the surface of the limiting block 12 is slidably connected to the top and bottom of the adjusting plate 102.

[0039] Specifically, such as Figure 4 As shown, the top of the connecting seat 204 is provided with a rotating groove 13, and the inner wall of the rotating groove 13 is slidably connected to the surface of the limiting ring 203.

[0040] In this embodiment: by setting the limiting block 12, the limiting block 12 can achieve the effect of limiting the top and bottom of the adjusting plate 102; by setting the rotating groove 13, the rotating groove 13 can achieve the effect of limiting the rotating connection of the limiting ring 203.

[0041] Working principle: First, based on the plastic part to be injection molded, select the matching mold 8 and module 9. The connection and fixing structure of mold 8 and module 9 is the same, so they are snapped onto the limiting plate 202 by the connecting bracket 201. Then, fix mold 8 and module 9 with fixing bolts. Then, connect the injection head to the injection hole on the top of mold 8. Then, the mold 8 and module 9 can be snapped together by the hydraulic rod 7. Then, the injection material is injected into the mold 8 through the injection head, and the injection material is extruded and shaped by the pressure of module 9. Then, the injection-molded material is quickly cooled and shaped by the cooling structure built into the mold 8. After the material is shaped into a plastic part, mold 8 is adjusted back to the top. Then, the front and back of the grinding machine 106 and grinding head 107 can be adjusted by the electric telescopic column 105, and the left and right of the connecting block 104 and electric telescopic column 105 can be adjusted by the transmission belt 103. The telescopic plate 101 adjusts the height of the adjusting plate 102, allowing the grinding machine 106 and the grinding head 107 to be adjusted arbitrarily in the same direction, thus performing grinding on the injection-molded plastic parts. During the grinding process, the first motor 206 can be turned on, causing the rotating rod 205 to rotate, which in turn causes the limiting plate 202 to rotate, thereby adjusting the rotation direction of the plastic parts and performing all-round grinding on the surface of the plastic parts. After the grinding is completed, the second motor 209 is turned on, causing the adjusting rod 208 and the rotating plate 207 to rotate, thereby flipping the module 9 so that the plastic parts on the module 9 fall into the collection device for collection. The first motor 206, the second motor 209, the transmission belt 103, the electric telescopic plate 101, and the electric telescopic column 105 are all remotely intelligent controlled.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
