Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically a color mixing flow channel structure. Background Technology

[0002] A color-mixing runner structure is a runner system design used in injection molding to achieve the mixing of multiple colors of molten plastic. Its core lies in the fact that through a specific runner layout and structural design, different colored plastics are fully mixed in the runner before being injected into the mold cavity, thereby obtaining a uniformly mixed plastic product. The runner is designed with multiple converging channels to guide different colored plastics to the same mixing area. Through the special structure within the runner (such as spiral runners, staggered runners, etc.), turbulence and convection are forced into the flow of the plastic, promoting uniform color mixing.

[0003] The existing color mixing channel does not achieve good self-mixing effect by relying solely on material flow, and the material is viscous, resulting in a slow material flow rate and affecting the feeding speed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a color mixing channel structure, which effectively solves the problems of poor self-mixing effect of existing color mixing channels that rely solely on material flow, and the viscous nature of the material resulting in slow material flow and affecting the feeding speed.

[0006] Preferably, the transmission assembly includes an upper gear, which is fixedly installed at the output end of the drive motor. A positioning frame is rotatably installed on one side of the upper gear, and one end of the positioning frame is fixedly connected to the upper part of the support frame. A lower gear is meshed with the lower part of the upper gear, and a shaft is fixedly installed in the middle of the lower gear. Both ends of the shaft surface are rotatably installed with bushings, and the bottoms of the two bushings are fixedly connected to the inner bottom of the protective cover through a fixing rod.

[0007] Preferably, both ends of the shaft are fixedly mounted with driving bevel gears, the lower parts of the surfaces of the two driving bevel gears are meshed with driven bevel gears, the bottoms of the two driven bevel gears are fixedly mounted with first drive shafts, the upper ends of the surfaces of the two first drive shafts are rotatably connected to the top of the mold through first sealed bearings, and the lower parts of the two first drive shafts extend into the interior of the color mixing cavity and are fixedly connected to several dispersing rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator injects two different colored materials into the interior of the two channels through two nozzles and they flow into the interior of the color mixing chamber. At the same time, the operator starts the drive motor to drive the upper gear to rotate along the positioning frame. When the upper gear rotates, it drives the shaft to rotate along the interior of the two bushings through the lower gear. When the shaft rotates, it drives the two driven bevel gears to rotate through the two active bevel gears. When the two driven bevel gears rotate, they drive the two first drive shafts to rotate along the interior of the two first sealed bearings. When the two first drive shafts rotate, they drive several dispersing rods to rotate, thereby dispersing and throwing the materials flowing down from the two channels into the interior of the color mixing chamber for thorough mixing.
