[0002] Injection flow channel is widely used in multiple fields, including household appliances, automobiles, medical devices and the like, in these fields, injection flow channel can produce various high-precision, high-quality plastic parts, meet the high requirements of industry to part production, small plastic parts often adopt multi-cavity row position flow channel forming, because the material flow rate of each part is not the same in the injection process, the material sprayed by each injection nozzle is also different, which leads to the size difference of the produced parts and injection defects, the existing injection flow channel installs the vertical pipeline at the output end of the branch flow pipe, makes the material can carry out flow channel turnover, reduces the difference of each part material spray, but cannot keep the stable flow of injection material, the difference of each injection material spray is still big. SUMMARY

[0003] In view of the defects that the existing injection flow channel cannot keep the stable flow of injection material and the difference of each injection material spray is big, the utility model provides a flow channel of water gap material full fusion, which can keep the stable flow of injection material and the difference of each injection material spray is small.

[0004] The utility model provides the following technical scheme:

[0005] It includes injection flow pipe and main flow pipe, injection flow pipe is installed in the middle part of main flow pipe perpendicularly, and main flow pipe is installed with branch flow pipe side by side, and both ends of branch flow pipe are provided with flow channel turnover structure, and flow channel turnover structure includes main flow pipe, branch flow pipe, low position branch flow pipe, vertical branch flow pipe and double -end injection nozzle, and its characterized in that: main flow pipe, branch flow pipe, low position branch flow pipe, vertical branch flow pipe and double -end injection nozzle are connected in turn in vertical direction and are communicated.

[0006] Its further features are:
