Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a fastener positioning device for molds. Background Technology

[0002] Mold fastener positioning devices are used during mold design and manufacturing to ensure precise positioning between mold components (such as mold plates and mold cores). The main function of these devices is to ensure that the various parts of the mold maintain the correct relative position during assembly and operation, avoiding offset or asymmetry, thereby guaranteeing the dimensional accuracy of the product and the service life of the mold. Mold fastener positioning devices include locating pins, locating rings, and bolts / fastening screws, which ensure the positioning connection of various parts of the mold and reduce offset.

[0003] Currently, during the use of molds, locating pins and locating rings are usually used to fix the various parts of the mold to prevent displacement during processing. Since the upper and lower molds are positioned by locating pins, the locating pins will wear or be damaged during long-term use. As the wear intensifies, the positioning accuracy may decrease, affecting the accuracy and lifespan of the mold. Utility Model Content
