  • Injection moulding die locking and opening device
    Patent number: 6220848
    Abstract: A locking and opening device for an injection moulding die, particularly for processing highly liquid melted plastic material, provides a technically simple, low cost mechanism to lock the die and limit elements located above workbench level or mould level, when the device is arranged vertically. To achieve this, clamping pins hold one moulding die in a closed position in relation to an overlying moulding die and which can be axially displaced into a closed or open position by means of a sliding element associated with each clamping pin.
