ABSTRACT:
The apparatus consists of a weight iron (1) with a plane bottom face designed to rest on the top side (3) of the upper mold of a two part sand mold set (2,6), and a clamping plate (4, 5) located at either side of the closed mold parts (2, 6). The bottom face (7) of the lower mold (6) rests on a transport device (8). The apparatus also includes L-shaped arms (9, 10), which pivot with respect to the weight iron (1) and the two side clamping plates (4, 5). The two L-shaped arms (9, 10) are placed opposite to each other in a vertical plane through the mold parts (2, 6). The arms (9, 10) are laterally off-set and pivot with the weight iron (1) at points (16, 17).
