Abstract
A machine for manufacturing polystyrene foam products, whereby a mold comprising a first half and a second half mold defining a molding chamber when closed, is loaded, with the two half molds locked in the closed position, onto the machine and into an operating position wherein the mold is connected automatically to granular polystyrene and utility fluid supply lines. In this operating position, the two half molds are rendered mutually mobile with the first half mold, connected to the utility supply lines, remaining locked to a fixed frame on the machine, and the second half mold remaining locked to a mobile frame on the machine.
Claims4
A machine (1) for manufacturing polystyrene foam products, said machine (1) comprising:
- a fixed frame (2);
- a mobile frame (3) connected to said fixed frame (2) so as to move, in relation to said fixed frame (2), back and forth in a given operating direction (4) and to and from a contact position;
- a mold (25) comprising a first half (26) and a second half (27) mold defining, when in a closed position, a molding chamber (28);
- a line (37) supplying granular polystyrene;
- a number of lines (38, 38a, 39) supplying utility fluids, each said supply line (37, 38, 38a, 39) comprising an input portion (40, 41, 41a, 42) on said fixed frame (2) and an output portion (43, 44, 44a, 45) on said first half mold (26);
- first (16) and second (60) lock means for respectively locking said first half mold (26) in an operating position on said fixed frame (2) and said second half mold (27) onto said mobile frame (3), said first lock means (16) comprising bolt means, said second lock means (60) comprising releasable coupling means (61, 70) for connecting said mobile frame and said second half mold (27);
- releasable means (54) for connecting said half molds (26, 27) in said closed position;
- and
- a mobile half coupling (50) and a fixed half coupling (51) located on each said supply line (37, 38, 38a, 39) and arranged facing each other in said operating direction (4), said mobile and fixed half couplings (50, 51) of each said supply line (37, 38, 38a, 39) being connected in said operating position so as to connect said respective input (40, 41, 41a, 42) and output (43, 44, 44a, 45) portions, and being respectively integral with said fixed frame (2) and said first half mold (26).
