    • A mold assembly or system includes a moldbase that holds mold inserts and has embedded fluid lines to facilitate cooling during part formation. Mold inserts combine to form mold cavities that receive carbon fiber and resin components to form a carbon composite based part. A permanent release coating along a mold component surface that contacts the carbon fiber and resin components facilitates the release of the finished part from the mold component. Guide pins and guide pin receiving holes facilitate accurate alignment of mold components. Ejector pins within respective ejector pin shafts help eject a finished part from a respective mold component. An ejector pin shaft cover transfers force from an ejector pin to eject a finished part and also prevents substantial passage of resin into the ejector pin shaft. A fluid actuated ejection system provides fluid based mechanical forces to the ejector pins to facilitate finished part ejection.
    • 模具组件或系统包括保持模具插入件的模具基座,并且具有嵌入式流体管线以便于部件形成期间的冷却。 模具插入件组合形成模腔,其容纳碳纤维和树脂组分以形成基于碳复合材料的部件。 沿着与碳纤维和树脂部件接触的模具部件表面的永久性脱模涂层有利于成品部件从模具部件的释放。 导销和导销接收孔有助于模具部件的精确对准。 相应的顶针轴内的推杆有助于从相应的模具部件弹出成品零件。 顶针轴套从顶针传递力,以弹出成品部件,并且还可防止树脂大量通入推杆销轴。 流体致动的喷射系统向喷射器销提供基于流体的机械力以便于最终的部件喷射。
