The main parts of the guide mechanism include a guide bush and a guide post, which play a very important role in the overall guide. The entire guiding mechanism plays three main roles in the injection mold.

(1) Positioning function: After the injection mold is closed, ensure the correct position of the movable and fixed molds or the upper and lower molds, and ensure the shape and size of the cavity; the guiding mechanism also plays a positioning role during the assembly process of the injection mold, which is convenient for assembly and adjustment.

(2) Guiding function: When the mold is closed, the first is to guide the parts to contact, guide the movable fixed mold or the upper and lower molds to close accurately, and prevent the core from entering the mold.

(3) Bear a certain lateral pressure: the molding cavity causes damage to the molded parts. The material melt may generate one-way lateral pressure during the filling process, or due to the influence of the low precision of the molding equipment, the guide post bears a certain lateral pressure to ensure the normal operation of the injection mold. If the lateral pressure is very large, the guide column cannot bear it alone, and a tapered surface positioning mechanism needs to be added.

The guide post and guide bush can effectively maintain the service life of the production mold and ensure the quality of the die: the connection between the upper and lower molds can be effectively realized to ensure better processing results. The guide sleeve guide pin can effectively maintain the gap between the dies, ensuring that the guide sleeve guide pin is used to maintain its machining effect.

It can provide better protection for the maintenance and handling of subsequent dies: the guide sleeve guide post can also stabilize the quality of the die, bring better results for subsequent use and processing, and ensure that the subsequent processing and production of the die, the quality is more stable, which can save a lot of labor and effort.
