Pattern plate drawing apparatus

An apparatus for drawing a pattern plate upward from a carrier plate, said apparatus comprising:

• a pattern plate;
• a carrier plate which holds the pattern plate, wherein the carrier plate is configured to move the pattern plate along a transport path;
• a fixed frame member disposed below said transport path;
• a first lifting cylinder mounted on said frame member, said first lifting cylinder having an upwardly extendable piston rod;
• a mount table secured to a tip end of said first lifting cylinder piston rod;
• and
• second and third lifting cylinders mounted on said mount table in a spaced-apart relationship, said second and third lifting cylinders each having an upwardly extendable piston rod, said second and third lifting cylinders each including a mount plate secured to a tip end of said piston rod and a plurality of draw pins mounted upright on said mount plate, wherein each of the second and third lifting cylinders is configured to be moved into a position in which at least one of the draw pins thereof engages the pattern plate and pushes said pattern plate upward relative to the carrier plate.

An apparatus for drawing a pattern plate upward from a carrier plate, comprising:

• at least one pattern plate;
• a carrier plate which holds the at least one pattern plate, wherein the carrier plate is configured to move said at least one pattern plate along a transport path, said carrier plate having a plurality of throughbores in the bottom thereof;
• a first lifting cylinder fixedly mounted below said transport path, said first lifting cylinder having an upwardly extendable piston rod;
• a mount table secured to a tip end of said first lifting cylinder piston rod;
• and
• second and third lifting cylinders mounted on said mount table in a spaced-apart relationship, said second and third lifting cylinders each having an upwardly extendable piston rod, said second and third lifting cylinders each including a mount plate secured to a tip end of said piston rod and a plurality of draw pins mounted upright on said mount plate, wherein each of the second and third lifting cylinders is configured to be moved into a position in which at least one of the draw pins thereof engages the at least one pattern plate and pushes said at least one pattern plate upward relative to the carrier plate.
