Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, specifically a high-efficiency mixing mechanism for colored masterbatch inside an injection molding machine. Background Technology

[0002] Injection molding machines are the main equipment used for molding and processing plastic products. The injection molding machine is equipped with a mold. The plastic granules in the hopper are heated and extruded into the mold through the extrusion mechanism. Then the mold is opened to make a plastic product that matches the shape of the cavity inside the mold. In the current injection molding process, a colored masterbatch mixing mechanism is generally used to mix the plastic granules and masterbatch according to the required color in advance. Then the mixed plastic granules and masterbatch are put into the injection molding machine for injection molding.

[0003] Existing colored masterbatch mixing mechanisms often suffer from low mixing efficiency during use. Firstly, the position of the stirring rod is fixed, which means it can only stir the material in a fixed location and cannot stir the material comprehensively, resulting in low mixing efficiency. Secondly, it lacks the function of tapping and vibrating the material box, which makes the material easy to stick to the inner wall of the material box, which not only makes it difficult to discharge the material but also leads to low mixing efficiency. Therefore, to address the above problems, a high-efficiency colored masterbatch mixing mechanism for injection molding machines is proposed. Utility Model Content

[0030] Working principle: The materials to be mixed are placed into the material bin 2. Then, the first motor 4 and the second motor 9 can be turned on. When the first motor 4 is turned on, it drives the stirring rod 6 to rotate in conjunction with the rotating rod 5 to stir the materials. When the second motor 9 is turned on, it drives the rotating block 11 to rotate in conjunction with the turntable 10. The rotation of the rotating block 11 drives the lifting shell 12 to move up and down reciprocally. The lifting shell 12, in conjunction with the lifting rod 13 and the lifting block 3, drives the first motor 4, the rotating rod 5, and the stirring rod 6 to move up and down reciprocally, increasing the utilization of the stirring rod 6. Within the range, the lifting shell 12, in cooperation with the lifting sleeve 708, can drive the adjusting block 709 to move up and down reciprocally. The up and down reciprocating movement of the adjusting block 709 will drive the adjusting shell 710 to move left and right. The adjusting shell 710, in cooperation with the moving plate 704 and the connecting rod 707, can drive the striking plate 705 to move left and right reciprocally. The striking plate 705 drives the striking block 706 to move left and right reciprocally to strike the material box 2. This not only prevents the material from adhering to the inner wall of the material box 2, but also plays a role in preventing blockage. In addition, it can also improve the mixing efficiency of the material.
