Abstract

An injection-moulding machine with a movable and a stationary mould-clamping plate (1, 2), wherein struts (4) are mounted in the stationary mould-clamping plate (1, 2), the struts connecting together the movable and stationary mould-clamping plates (1, 2) during the injection operation. The movable mould-clamping plate (2) is able to travel on rails (9) by way of a bracket-like running shoe (14), and, on opening the mould, is able to be released from the struts (4). Carriages (17) with rollers (18) are provided which are pivotally mounted to the movable mould-clamping plate (2) and which are tiltable about a horizontal axis (19) relative to the mould-clamping plate (2) and relative to the running shoes (14). Each running shoe (14) has a front roller (15) which can be raised from the rails (9) and lateral guide rollers (20) with vertical axes of rotation which roll down smooth guide surfaces (30) of the rails (9) and which are likewise raised from the rails (9) during the injection operation.
