Description

Technical Field

[0001] The utility model belongs to the technical field of flow splitters, and more specifically, particularly relates to a wear-resistant flow splitter for a flash evaporation device. Background Art

[0002] The flow splitter is also called a hot runner flow splitter. It is the central component of the hot runner system. It distributes the plastic melt transmitted from the main runner nozzle to each injection point nozzle through the runner. The flow splitter can evenly fill the cavities of the mold, make the plastic flow evenly, and balance the system heat. The existing flow splitters of flash evaporation devices are prone to runner wear after long-term use, thus requiring regular replacement. Not only is the disassembly and installation process cumbersome, but also the cost is relatively high. Therefore, a wear-resistant flow splitter for a flash evaporation device is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a wear-resistant flow splitter for a flash evaporation device, which evenly injects the injection fluid into the injection holes. Since both the main pipe and the first branch pipe and the second branch pipe are made of ceramics, the wear resistance of ceramics is extremely strong, thus greatly reducing wear, so as to solve the problems that the existing flow splitters of flash evaporation devices are prone to runner wear after long-term use, thus requiring regular replacement. Not only is the disassembly and installation process cumbersome, but also the cost is relatively high as mentioned in the above background art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A wear-resistant flow splitter for a flash evaporation device, including a plate body. A plurality of injection holes are opened on the top surface of the plate body. A runner system is opened inside the plate body. The runner system includes a main runner, four first branch runners, and eight second branch runners. A main pipe is provided inside the main runner. Both ends of the main pipe are threadedly connected with first screws. A plurality of first runner holes are opened on the top surface of the main runner. Two second runner holes are opened on both sides of the main pipe. First branch pipes are provided inside the four first branch runners. Third runner holes are opened on the top surface of the first branch pipes. Fourth runner holes are opened on both sides of the first branch pipes. One end of the first branch pipe away from the main pipe is threadedly connected with a second screw. Second branch pipes are provided inside the eight second branch runners. One end of the second branch pipe away from the first branch pipe is threadedly connected with a third screw. Fifth runner holes are opened on the top surface of the second branch pipes. Threaded caps are abutted against the exposed ends of the main pipe, the first branch pipe, and the second branch pipe. A threaded cylinder is abutted against the inside of the threaded cap. One end of the threaded cylinder is fixedly connected with the outer side of the plate body.
