Injection molding apparatus having a cooling core with 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.
摘要（中）：

具有每个细长的冷却模芯（10）的注塑设备具有围绕中央冷却流体管道（104）延伸的多个冷却流体孔（118）或凹槽（134）。 整体的圆顶形前盖（76）包围开放的前端（78）。 圆顶盖（76）的内表面（130）具有弯曲肋（132），其形成与冷却流体孔（118）或槽（134）对准的弯曲冷却流体槽（134）。 弯曲的肋（132）给予圆顶形前盖（76）更多的强度，其允许其更薄，其中弯曲的冷却流体槽（134）更靠近空腔（66），以提高冷却效率。
