注塑模具中用于保证各活动零件在开、合模时运动畅顺、准确复位，以及在注塑

The part of the injection mold used to ensure that the moving parts move smoothly and accurately reset when opening and closing the mold, and will not be misaligned and deformed under the action of the injection molding machine clamping force and melt expansion force are collectively called the mold guide GPS. Among them, the structure in the injection mold that guarantees the movement of the moving parts according to the predetermined trajectory is called the guidance system; the structure that guarantees the relative positional accuracy between the front and rear molds and the moving parts is called the positioning system. <br>Guide parts include guide post and guide sleeve. <br>Positioning parts include side locks and inner mold tube positions.

The injection mold is used to ensure that the moving parts in the open, the mold movement smooth, accurate reset, as well as the injection molding machine lock force and melt rising force under the action of the part of the mechanism will not misplace deformation is collectively called the mold guidance positioning system. The structure of the active part in the injection mode to ensure the active part in accordance with the structure of the established trajectory motion is called the guidance system, and the structure which guarantees the relative position accuracy between the front and rear molds and between the moving parts is called the positioning system.<br>Guided parts include guide posts and guide sleeves.<br>Positioning parts include edge locks and inner die tube positions.

The guiding and positioning system of the injection mold is a part of the mechanism used to ensure the smooth and accurate movement of the moving parts when opening and closing the mold, and to prevent dislocation and deformation under the action of the locking force of the injection molding machine and the expanding force of the melt. Among them, the structure that ensures the moving parts to move according to the given track in the injection mold is called the guiding system, and the structure that ensures the relative position accuracy between the front and rear molds and between the moving parts is called the positioning system.<br>Guide parts include guide post, guide sleeve, etc.<br>Positioning parts include side lock and inner die tube position.
