Abstract: A moulding press for a moulding device which comprises two mould halves movable relative to each other. The mould halves are connected by a pair of spaced joint linkages located opposite one another. Each joint linkage includes two pivotable arms which are connected in a hinge-like manner to each other and to a respective first and second plate. Control arms engage the joint linkages and are movably coupled to a control element. Movement of the control element will result in link motion of the control arms and cause movement of the mould halves toward each other or away from each other.

Abstract: Device for injecting a plastic material into a mould cavity. In the device, the plastic is moved into the mould cavity by a plunger. The first part of the press stroke is used to transport the material and has to be carried out at relatively low pressure and over a relatively long transport path. The second part of the press stroke is used to fill the mould completely and takes place at relatively high pressure and virtually no stroke. According to the invention, the two movements are effected by different mechanisms which are specifically adapted to carry out these movements. In this arrangement, it becomes possible also to provide a safety coupling to prevent the device being overloaded while working at relatively low pressure.
