Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a plastic removing structure of an injection molding machine with adjustable height. Background Technique

[0002] When the injection molding machine is working, the plastic raw materials will enter the mold through the barrel, and then be heated and compressed into shape, and finally the products are taken out of the mold. In this process, it is necessary to clean and maintain the raw materials in the barrel of the injection molding machine, so as to facilitate the replacement of different materials or colors, reduce cross - contamination and production downtime.

[0003] For example, in the Chinese patent with the application number 202323030988.X, a plastic cleaning device for an injection molding machine with adjustable height is provided. Through the setting of structures such as a semi - gear and a main threaded rod, when the cleaning motor is started, the rotating shaft rotates, driving the wheel disc and the semi - gear to rotate. The rack and the semi - gear are in the same direction. The small gear rotates forward when it contacts the rack and rotates backward when it contacts the semi - gear, driving the main threaded rod to rotate in the same direction, and the slider moves up and down, so that the scraper performs repeated up - and - down cleaning. Through repeated up - and - down cleaning, it can ensure that the residues inside the barrel are completely removed, quickly and effectively remove the residues inside the barrel, shorten the cleaning time and downtime, and thus improve production efficiency.

[0004] However, when this type of cleaning device is in use, the lateral position of its scraper is inconvenient to adjust. When the size of the barrel is large, the scraper may not contact the inner wall of the barrel, resulting in no cleaning effect.

[0005] Therefore, in view of this problem, the utility model provides a plastic removing structure of an injection molding machine with adjustable height. Summary of the Utility Model

[0024] Refer to Figures 1 - 4 , the adjustment component 7 further includes a return spring 73 sleeved on the outer surface of the sliding rod 71, the two ends of the return spring 73 are respectively fixed to the installation strip 72 and the scraper 6, a triangular strip 74 is fixed to the side surface of the installation strip 72 away from the installation strip 72, and fixing holes 75 are arranged in an array on the triangular strip 74.

[0025] Refer to Figures 1 - 4 , the adjustment component 7 further includes a pull rod 76 sliding in the rotating rod 4 and the installation box 5, an extrusion rod 77 is fixed on the outer surface of the pull rod 76, and the extrusion rod 77 is slidably connected to the fixing hole 75.

[0026] Refer to Figures 1 - 4, the driving assembly 8 includes an L-shaped frame 81 fixed to the top of the top cover 3. A motor 82 is fixed on the L-shaped frame 81, and a driving gear 83 is fixed to the output shaft end of the motor 82.
