Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a deburring device for processing plastic products. Background Art

[0002] Plastic products are prone to burrs during production due to poor mold design or machining. During the injection molding process, molten plastic enters the mold, where the mold walls and flow paths influence the plastic's shape. Improperly smooth mold surfaces or improper mold design can lead to burrs after injection molding. Additionally, improper settings of the injection molding machine's pressure, speed, and other parameters can cause the plastic to flow too quickly or too slowly, creating burrs.

[0003] During the production of plastic products, burrs are primarily concentrated on edges, but they also appear on flat and curved surfaces. Currently, a common method is to use a grinder to remove these burrs, but this presents several challenges. Using a grinder on edges can easily lead to over-grinding and damage, requiring skilled workers to operate with exceptional skill. Furthermore, for curved surfaces, the use of a grinder is less efficient, requiring constant flipping of the plastic product to achieve optimal deburring results, increasing production costs and labor.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Edge burrs are easily polished: The device can adjust the extension of the grinding head according to the shape and size of the plastic product. The extension is adjusted by the electric push rod and the distance meter reading is used to determine the extension of the grinding head, so as to accurately remove burrs on the edge of the plastic product. This step-by-step method makes the polishing more precise and controllable, helping to improve the surface quality of the product.

[0013] Prevent over-grinding: The motor-driven grinding head and screw lifter precisely grind the edges and curved surfaces of plastic products, preventing distortion or damage caused by over-grinding. The control panel allows for better monitoring and adjustment of the grinding process, ensuring the desired results.

[0014] Differentiated grinding of curved and flat surfaces: The device is equipped with mesh grinding boxes, including flat and curved surface grinding boxes, which can be selected and switched according to different grinding requirements. This ensures that curved and flat surfaces can be ground separately, meeting the processing requirements of plastic products of different shapes and improving processing flexibility and applicability.
