Description

Technical Field

[0001] The present application relates to the field of grinders, and in particular to a grinder for injection molded parts. Background Art

[0002] Injection molded parts refer to various injection molded products produced by injection molding machines. The selection of plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Injection molded parts are generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding, and thermoforming are used to shape plastics on a flat surface. However, after the injection molded parts are injection molded by the injection molding machine, the surface of the injection molded parts will still contain burrs, and the surface of the injection molding machine needs to be polished by a grinder later.

[0003] For example, the Chinese publication number CN216802842U discloses an injection molded part surface grinder that is easy to adjust. The injection molded parts are polished by the grinder and the clamp. However, the grinder can only grind one workpiece at a time, and when replacing the injection molded parts, the grinder needs to be stopped and the injection molded parts need to be clamped and then polished. This consumes the grinding efficiency of the injection molded parts and reduces production efficiency. Utility Model Content

[0027] In the present embodiment, each mounting seat 4 includes a fixed seat 41, a longitudinal movable seat 42 is arranged on the fixed seat 41, a transverse movable seat 44 is rotatably arranged on the longitudinal movable seat 42, and the cylinder 6 is mounted on the transverse movable seat 44.

[0028] Working principle of the injection molded parts grinding machine:

[0029] When it is necessary to polish the injection molded parts, firstly clamp a plurality of injection molded parts on each clamp 5 respectively, then start the cylinder 6 so that each injection molded part contacts the side of the polishing disc 3, then start the motor 2 so that the polishing disc 3 rotates, thereby polishing each injection molded part. Since the burrs of each injection molded part are different, the polishing time of each injection molded part is also different. Therefore, after polishing of an injection molded part is completed, start the cylinder 6 so that the injection molded part is away from the polishing disc 3, then remove the polished injection molded part and install the injection molded part to be polished, and start the cylinder 6 again so that the injection molded part is close to the polishing disc 3 for polishing. By setting a plurality of clamps 5, the polishing disc 3 can polish a plurality of injection molded parts at the same time during polishing, which can improve the efficiency of polishing the injection molded parts, thereby improving the production efficiency of the injection molded parts. By setting the cylinder 6, the grinding disc 3 can grind multiple injection molded parts and clamp each injection molded part individually, so that the grinding disc 3 does not need to be stopped when clamping the injection molded parts, thereby improving the production efficiency of injection molded parts.
