Description

Technical Field

[0001] The utility model relates to the technical field of injection molding processing, in particular to an automatic trimming and deburring device for injection molding. Background Art

[0002] Injection molded parts refer to plastic products made by injection molding. Injection molding is a common plastic processing method, usually used to produce a large number of plastic products. During the injection molding process, plastic particles are heated to a molten state, and then injected into the mold under high pressure. After cooling and solidification, the desired product shape is formed. Injection molded parts can be products of various shapes and sizes, such as parts, containers, shells, casings, etc., which are widely used in electronic products, automobiles, medical devices, household items and other fields. Due to the high efficiency and flexibility of the injection molding process, injection molded parts usually have good surface quality, precise dimensional control and cost-effectiveness advantages, so they have been widely used in industrial production.

[0003] After the injection molding is completed, burrs will be generated on the edges and interfaces of the injection molded parts due to the gaps between the molds. It is difficult to quickly and comprehensively trim and deburr the injection molded parts with the general trimming and deburring device when in use. The burr treatment effect of the injection molded parts is not good enough, which can easily reduce the appearance of the injection molded parts. During the subsequent processing or use of the injection molded parts, the burrs can easily pierce the body of the workers, which poses certain safety hazards. When the general trimming and deburring device is working, the polished waste is easy to float around and pollute the work surface. In view of the above problems, an automatic trimming and deburring device for injection molded parts is proposed to solve them. Utility Model Content
