发明名称 Mold pin lock
摘要 A mold comprises at least two separable parts defining at least one parting line. In this invention, a passageway is defined in one of the separable parts, while a pin, positioned in the passageway, is secured to another of the separable parts. The passageway and pin extend essentially in the direction that the separable parts move to open and close their parting line. A slot is defined in the separable part that defines the passageway, the slot communicating between the passageway and the exterior of the mold. When the mold is closed, a portion of the pin occupies the slot. Accordingly, lifting means can enter the slot to engage the pin when the mold is closed, for lifting thereof, and longitudinal movement of the pin in the slot can be prevented, to lock the mold, while the pin is so engaged.
