Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an anti-blocking and cleaning mechanism for a nozzle of an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it eject and fill the mold cavity.

[0003] The nozzle of the injection molding machine will be clogged after working for a long time. At present, the method of cleaning the nozzle of the injection molding machine on the market is to remove the nozzle and clean it with a brush roller. The cleaning efficiency and the thoroughness of the internal cleaning are low and the angle cannot be adjusted. It will be repeatedly clogged during use, which is a heavy workload for the staff. Therefore, an injection molding machine nozzle anti-clogging cleaning mechanism is proposed to solve the above problem. Utility Model Content

[0029] In summary, the anti-blocking cleaning mechanism for the injection molding machine nozzle, when cleaning, first starts the second electric push rod 8, and its output end drives the fixed pile 7 and the rack 302 to move forward and backward, and the rack 302 moves forward and backward to drive the movable rod 303 on its outer side to move left and right, and the movable rod 303 moves left and right to drive the clamping block 305 to move left and right, and the clamping block 305 moves left and right to drive the sliding plate 306 and the connecting block 307 to move left and right to clamp and fix the nozzle, and then starts the brush roller 9 to clean the outer surface of the nozzle. Because the sliding plate 306 and the clamping block 305 are slidably connected, the nozzle can continuously adjust the cleaning surface during the cleaning process to complete the preliminary cleaning, and then start the first electric push rod 4 to drive the rack 302 to move up and down to the cleaning, and then start the ultrasonic cleaning instrument 10 to drive the cleaning liquid in the outer box 1 to thoroughly clean the small gap inside the injection molding machine nozzle, which solves the problem that the cleaning method of most existing injection molding machine nozzles and barrels is to remove the barrel and rinse it with water, the cleaning efficiency and the thoroughness of the cleaning inside are low, and the workload of the staff is heavy.
