Stripper guide pins are a common type of mold guide pin, similar to independent guide pins. Their primary function is to form a guiding mechanism between the stripper plate and the fixed plate of the female mold, ensuring accurate alignment. Consistent with the interference fit used in the fixed plate of the female mold, the tolerance of stripper guide pins is designed as a positive tolerance.
High-precision internal guide pins are made from bearing steel (Gcr15), and they undergo overall quenching as a heat treatment method, with hardness controlled within the range of 58-62 degrees. This treatment fully leverages the toughness and wear resistance of bearing steel, effectively preventing guide pin breakage and extending the service life. The precision of the guide pins is controlled within 0.005mm to ensure high compatibility between the guide pins and the guide bushing, enhancing mold assembly efficiency.
Characteristics and advantages of internal guide pins:
- Meticulous material selection to ensure comprehensive guarantees in hardness and durability.
- Manufacturing processes are overseen by senior engineers to ensure product tolerances and precision.
- Good interchangeability, convenient installation and use, saving time.
Stripper guide pins are commonly used in injection molds, die-casting molds, and various other mold systems. Their main role is to ensure accurate alignment of various components within the mold, ensuring stability and efficiency in the production process. Here are some common application areas:
- Injection Molds: In the plastic injection process, stripper guide pins ensure proper alignment of various components in the mold for smooth injection molding.
- Die-casting Molds: During the die-casting process, stripper guide pins help secure the stripper plate and the fixed plate of the female mold to ensure the quality and precision of the castings.
- Mold Manufacturing: In the manufacturing of molds, stripper guide pins are used for assembly and positioning, ensuring the accuracy and stability of the mold structure.
- Precision Machining: Due to their high precision and compatibility, stripper guide pins are also applied in precision machining fields requiring high precision and stability.
