<p>The invention relates to an apparatus for minimizing waste in injection mouldings from injection moulding machines of known type, having an injecting and plasticizing unit (1, Fig 1 not shown) on the one hand and a closing unit (10, 12; Fig 1 not shown) on the other hand, the closing unit having, in or along the parting plane (15) of the mould halves (5, 6), a plurality of mould nests (16) which can be opened and closed and can be filled by way of a system of distributor channels with a viscous, solidifiable rubber or synthetic material, and at least one wall region of each mould nest aligned perpendicular to the direction of closing the closing unit being formed or supported by the membrane-like wall (72) of a cavity (73), which can be acted upon by a fluid, in at least one mould half (6), the cavity (73) being filled with a constant quantity of fluid is closed in pressure-tight manner and its wall regions (74), which are aligned parallel to the direction of closing, being formed in this direction to be both in one part and also yielding. <IMAGE></p> |
