Technical Field

[0001] The utility model belongs to the technical field of trimming the flash of injection-molded products, in particular to a trimming machine for trimming the flash of injection-molded products. Background Art

[0002] Injection molding is a method for producing industrial products. It is generally divided into three types: rubber injection molding, plastic injection molding and molding injection molding. Rubber injection molding is a production method in which the rubber material is directly injected from the barrel into the model for vulcanization. It has a short molding cycle, high production efficiency and excellent product quality. Plastic injection molding is a method for plastic products. The molten plastic is injected into the plastic product mold under pressure, and the desired plastic parts are obtained by cooling and molding. There are mechanical injection molding machines specifically used for injection molding. The most commonly used plastic is polystyrene. The shape obtained by molding injection molding is often the final product. No other processing is required before installation or use as the final product. Many details, such as bosses, ribs, and threads, can be molded in a one-step injection molding operation.

[0003] The authorization announcement number is CN214351519U, and the authorization date is 2021.10.08. The "handheld edge grinding device for injection molded parts" includes: a handle, a bracket, an edge grinding wheel and a driving motor. The edge grinding wheel is installed on the bracket. The bracket includes a middle top plate and side plates on both sides. The edge grinding wheel includes a wheel surface and a wheel axle. A bearing is installed between the wheel axle and the side plate. The wheel axle passes through one side of the side plate.
