Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically an automotive connector molding mold. Background Technology

[0002] Automotive connector housings are typically manufactured using injection molding. Their complex shapes, uneven wall thicknesses, and numerous thin-walled clips and positioning ribs make them prone to air trapping during molten metal filling. Venting relies solely on the parting line or additional venting slots, resulting in a small venting area and fixed locations. Furthermore, mold disassembly and assembly are labor-intensive, leading to long downtimes. Therefore, there is an urgent need for an automotive connector injection mold that offers efficient venting, rapid disassembly and assembly, and a compact structure. Utility Model Content
