摘要

A mould closing means, in particular for die-casting and injection moulding machines for metals and synthetic materials, having a fixed mould support plate received on pillars, a fixed end plate and a mould support plate, which can be moved between the latter from the open into the closed position, by means of at least two piston-cylinder arrangements engaging the fixed mould support plate or the end plate, a pressure element serving to produce the closing pressure being secured to the end plate, and a pressure plate being located thereon which can be swung from the engaged position between the pressure element and movable mould support plate, about a pillar, into a disengaged position, which is mounted to move axially and which can be infinitely adjusted to various lengths, which is characterized in that the swinging lever supporting the pressure plate is received on the pillar in a pivot bearing fixed in axial direction, and the pressure plate is received in the swinging lever so as to be axially movable against the action of springs, the travel of the springs being smaller than the stroke of the pressure element.
