Essential Properties of Injection Mold Bases
Injection mold bases are crucial components of injection molds and directly impact the quality and lifespan of the mold. The essential properties of injection mold bases include:
Rigidity and Strength:
During the injection molding process, injection mold bases withstand immense injection and ejection pressures. Hence, they must possess adequate rigidity and strength to prevent deformation under these loads. Base rigidity is primarily determined by the base's structural design and material strength.
Dimensional Accuracy:
The dimensional accuracy of injection mold bases directly influences the dimensional precision of the molded products. Therefore, the base's dimensional accuracy must adhere to national standards. Base accuracy is primarily governed by the precision of the machining process and inspection methods.
Wear and Corrosion Resistance:
Injection mold bases are exposed to plastic, additives, and release agents during operation, necessitating excellent wear and corrosion resistance. The base's wear and corrosion resistance depend on the material properties and surface treatment processes.
Stability:
Injection mold bases must maintain stability during operation to prevent compromising the quality of molded products. Therefore, the base's stability must be adequate. Base stability is primarily determined by the structural design and material stability.
Maintainability:
Regular maintenance is essential for injection mold bases during their service life. Hence, they must possess good maintainability. Base maintainability is primarily influenced by the rationality of the base's structural design.
Regular maintenance are crucial for injection mold bases during their service life and primarily encompasses the following:
Cleaning: Regularly clean the base to remove dirt and debris.
Lubrication: Regularly lubricate the base's moving parts to minimize friction and wear.
Inspection: Regularly inspect the base for wear and promptly replace or repair worn parts.
