Detailed Description

The utility model will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.

Referring to fig. 1-4, the present utility model provides a technical solution: a novel high-precision hot runner injection mold is provided, wherein a feeding pipe is communicated with the top of an upper module close to the middle position, and the feeding pipe is convenient for materials to enter a mold cavity.

The top of the lower module is provided with an injection molding cavity, the injection molding cavity and the lower module are designed integrally, and the injection molding cavity is used for molding.

The air inlet arranged at the top of the fan is communicated with an air inlet pipe, the top of the air inlet pipe penetrates through the box body and extends to the outside of the box body, and the air inlet pipe plays a role in air inlet.

One side opposite to the two sliding blocks extends to the inside of the two sliding grooves respectively and contacts with the inner wall of the sliding grooves, the sliding blocks are connected with the sliding grooves in a sliding manner, and the sliding blocks enable the guide pipe to slide.
