Definitions

  • the ar-' rangement for guiding the movable plate of a press for casting metals in a chill mold remedies the difficulties due to expansion by absorbing and compensating the resulting dimensional changes, and it is particularly suited to large machines.
  • the press is noteworthy in having for this purpose a plate bearer simply resting on two slides and suspended from two horizontal columns of the machine.
  • the means for obtaining this compensation of expansion are of two sorts, first one in which the supports of the surfaces on which the movable plate slides are given such an inclination as to contain the main directions of expansion, and second, the movable plate is suspended from the guiding columns by means of two lateral rods.
  • This mechanism has in addition the advantage of preventing any rotation of the movable plate.
  • FIG- URE is a transverse view of a horizontal die casting machine, partially in section, with an arrangement included therein conforming with the present invention.
  • the movable plate 1 shown in right section with certain internal details in partial section, of a conventional horizontal die casting machine of the type also having a fixed part, receiving an injection tube, not shown, rests on-a guiding bed 4 of a machine consisting of two horizontal slides 2.
  • the movable plate 1 contacts the guiding bed 4 through slide blocks 2a thereon having contact surfaces 2b inclined to a horizontal plane at angles a and being chosen so that the main directions of expansion 0a, 0a originating at the center of the metal injection tube entering the die, and hence in the hottest point 0 thereof, being the central point of arrival of the liquid metal, and along which the deformations are the greatest, coincide with the directions of the planes of sliding in the right section of the arrangement.
  • two oppositely disposed linking rods or tether brackets 3 are rotatably carried from their top ends respectively on two horizontally disposed guiding columns 5 and support at their lower ends on pins 6 extending therefrom the two upper ends of the movable plate 1, the pins 6 being pivotally secured to the movable plate 1 to permit rotation of the rods 3 about columns 5 upon expansion or contraction of the movable plate.
  • a pair of linking members being respectively pivotally secured at an upper end thereof to different ones of said pair of guiding columns and pivotally secured at a lower end thereof to opposite ends of said movable plate;
