a fifth linkage articulated on the second linking surface;
a sixth linkage articulated on a frame of the machine.
a striker which strikes the mould in a portion selected from the base, a side wall, an end wall and combinations thereof; in other words, there can be a single striker in the base, a single striker in a side wall, a single striker in an end wall, or there can be different combinations in which there is a striker in any of the locations;
a pusher which pushes the ingot through a portion selected from the base, a side wall, an end wall and combinations thereof; in other words, there can be a single pusher pushing the ingot through a portion in the base, a single pusher through a side wall, a single pusher through an end wall, or there can be different combinations in which there is a pusher pushing through any of the locations;
