INJECTION MOLDING COOLING CORE HAVING A RIBBED CAP |
摘要 |
Injection molding apparatus with each elongated cooled mold core (10) having a number of cooling fluid bores (118) or grooves (134) extending around a central cooling fluid duct (104). An integral dome shaped front cap (76) encloses the open front end (78). The inner surface (130) of the dome shaped cap (76) has curved ribs (132) which form curved cooling fluid grooves (134) aligned with the cooling fluid bores (118) or grooves (134). The curved ribs (132) give the dome shaped front cap (76) more strength which allows it to be thinner with the curved cooling fluid grooves (134) being closer to the cavity (66) to improve cooling efficiency.
