The present invention relates to a post-extracting device for at least one post (7a, 7b, 7c, 7d) of a moulding machine (1), in particular a die-casting machine, said moulding machine having a fixed clamping plate (2) with a first casting-mould half (3) arranged thereon and a movable clamping plate (4) with a second casting-mould half (5) arranged thereon. The movable clamping plate (4) can be moved on posts (7a, 7b, 7c, 7d) detachably fastened in the fixed clamping plate (2), preferably four posts (7a, 7b, 7c, 7d) detachably fastened at the corners of the fixed clamping plate (2). The post-extracting device is characterised in that the post-extracting device has the following units: a fastening device (10a, 10b, 10c, 10d) arranged on the movable clamping plate (4), for detachably connecting to a post and a further fastening device (15a, 15b) for detachably connecting to a post, which is arranged on a bar (11a, 11b), which is located on the side of the movable clamping plate (4) facing away from the fixed clamping plate (2). The present invention further relates to such a moulding machine and a method for extracting a post from such a moulding machine.
