    • A pivot casting component used in an apparatus for extrusion blow molding polyethylene teraphthalate (“PET”) is disclosed. The pivot casting is designed to provide increased strength and increased reliability over prior components with the blow mold clamping linkage system. Prior art pivot elements were designed and fabricated from separate elements such that weak points, and stress concentration points were created. Such weak points resulted in the pivot element being a weak component in the blow mold clamping linkage system. The inventive pivot casting is cast as a single component from higher strength materials, with an improved geometry to increase component strength, durability and overall system reliability. In a preferred embodiment, the air side pivot casting is formed from 80-55-06 ductile iron resulting in a 40% increase in tensile strength over prior pivot components.
    • 公开了一种用于挤出吹塑聚对苯二甲酸乙二醇酯(“PET”)的设备中的枢轴铸件。 枢轴铸件的设计旨在通过吹塑模具夹紧连接系统提供更高的强度和更高的可靠性。 现有技术的枢轴元件由单独的元件设计和制造,使得产生弱点和应力集中点。 这种弱点导致枢轴元件在吹塑夹紧连接系统中是弱部件。 本发明的枢轴铸件由更高强度的材料铸造成单一部件,具有改进的几何形状以增加部件强度,耐久性和整个系统的可靠性。 在优选实施例中,空气侧枢轴铸件由80-55-06球墨铸铁形成,导致拉伸强度比先前的枢转部件增加40%。
