Description

Technical Field

[0001] The utility model relates to the technical field of nozzle removal of injection molding products, in particular to a nozzle removal device for injection molding products. Background Art

[0002] The sprue is a very important component of the injection molded part. It is the only part of the entire injection molding machine that comes into contact with the molded part. The sprue allows the molten material to enter the mold and fill the mold cavity. The sprue needs to be removed after the injection molding is completed.

[0003] After searching, the utility model patent with announcement number CN221495454U discloses a nozzle polishing device for injection molding parts, including a workbench, a polishing mechanism and a dust suction mechanism are arranged above the workbench; the polishing mechanism includes a baffle, an operating table, a guardrail, a screw, a connecting block 1, a connecting block 2, a polishing sheet, a motor, a clamping block, a support block, an electric push rod, a robotic arm, a gripper and an anti-slip strip, the baffle is fixedly connected to the upper surface of the workbench, the operating table is fixedly connected to the left end of the upper surface of the workbench, the guardrail is fixedly connected to the middle of the baffle, the screw is fixedly connected to the middle of the baffle, the motor is fixedly connected to the upper inner part of the baffle, and the right end of the connecting block 1 is threadedly connected to the screw; the nozzle polishing device for injection molding parts can effectively absorb dust generated during the polishing process through the design of the dust suction plate, the dust suction port, the slide 1, the slide 2, the filter and the air pump. The existence of this mechanism can timely remove the generated dust and avoid the spread of dust.

[0004] However, the above patent has the following shortcomings: when grinding and cleaning the sprue, it is difficult to control the downward movement distance of the grinding disc, which can easily result in insufficient grinding or excessive grinding, affecting the quality of the sprue cleaning. In addition, although the dust suction port and other structures can absorb the waste generated by grinding, the high position of the dust suction port makes it difficult to ensure that all the waste generated by grinding is cleaned. To address this problem, we propose a sprue cleaning device for injection molding products. Utility Model Content
