Injection mould

摘要

The invention relates to an injection mould for mouldings in the form of crates, in particular bottle crates, in which the mould jaw is displaceable on inclined guide pillars on the movable mould half by means of a drive and in which a stripper frame is provided on the displaceable mould jaw and can be used to strip the moulding from the core of the movable mould half once the mould jaws have been opened. A drive for the ejector frame is described, with which it is ensured that, without limit switches and the like, the stripping of the moulding from the core commences as soon as the mould is open far enough that the moulding can drop out of the opened mould. The ejector frame is in this case penetrated by at least two guide pillars, which are fastened in one of the two mould halves and by which the said mould half is guided in relation to the other mould half in the opening direction. On the guide pillars there are respectively mounted axially displaceable bushes, on the outside of which the guide frame and the other mould half are mounted axially displaceably. The bush is provided with stops, which interact with the ejector frame on the one hand and with the other mould half on the other hand, the effective distance between the stops being chosen such that the ejector frame is taken along during opening of the mould as soon as an opening width required for ejecting the moulding has been reached. <IMAGE>
