Hot/cold press forming apparatus for thermoformable plastic materials

An apparatus for forming and shaping a workpiece made of thermoformable plastic material, which comprises:

• (a) a base platen means;
• (b) a positioning means supported by said base platen means;
• (c) a tray means for supporting a raw workpiece, said tray means being supported by said positioning means;
• (d) a base means supported by said base platen means;
• (e) a first pair of dies;
• (f) a first support means for supporting said first pair of dies, said first support means being supported by said base means;
• (g) a first means mounted on said base means for moving said first support means whereby said first pair of dies may be positioned above said raw workpiece and below said tray means;
• (h) a second pair of dies;
• (i) a second support means for supporting said second pair of dies, said second support means being supported by said base means;
• (j) a second means mounted on said base means for moving said second support means whereby said second pair of dies may be positioned above said workpiece and below said tray means;
• (k) a press platen means;
• and
• (l) means for moving said platen means whereby said first pair of dies may be closed against said raw workpiece and said tray means when said first pair of dies is in position above and below said workpiece and said second pair of dies may be closed against said workpiece and said tray means when said second pair of dies is in position above and below workpiece.
