The invention concerns a device (1) at moulding tools (2) for hot-runner injection-moulding of plastic material and which comprises movable stock moulds (3, 4) guided by guides (5). Said guides (5) are arranged in milled-out recesses (7) in the respective corner (6) of the square- shaped mould. The receiving, milled-out square-shaped reception recesses (7) of the guides are arranged directed in a common direction (8) toward the centre (9) of the moulding tool whereby the thermal elongation of the tool is arranged to run in said direction (8) toward the centre (9) of the moulding tool. Furthermore, the guides (5), which extend into the two stock moulds (3, 4) of the moulding tool, are formed of a peg having a square-shaped head, which is guided by the receiving, square-shaped, milled-out reception recess (7). |
