Abstract
An apparatus for continuously sizing, preforming or forming metal objects includes a plurality of molds arranged in a substantially vertical column and which collectively define a mold cavity. Each mold is separable into at least two mold sections. A retaining mechanism retains the molds in the vertical column. A first and second screw arm assembly separates the bottom mold into sections and removes the mold sections from the bottom of the mold with a horizontally operable screw arm mechanism. The arm assemblies then move the mold sections from a bottom position to an uppermost position with a vertically movable screw arm mechanism. The horizontally movable screw arm mechanism then moves the mold sections to an uppermost position on the vertical mold column to form a top mold.
Claims5
An apparatus for continuously casting metal objects, the apparatus comprising:
- a plurality of molds arranged in a substantially vertical column defining a mold cavity, each mold having at least two mold sections separable from each other and the column having a top mold and a bottom mold;
- means for retaining the molds in the substantially vertical column;
- and
- means for separating mold sections of the bottom mold and for removing the bottom mold sections and for positioning the bottom mold sections on the top mold of the column forming a new top mold, said means for separating mold sections including first and second screw arm assemblies, each screw arm assembly including first screw arm means for moving a mold half in a substantially vertical direction and second screw arm means for moving a mold half in a substantially horizontal direction such that a bottom mold section is moved horizontally from a bottom position in the mold column when the screw arm means is in a lowermost position and is moved in an upward direction to an uppermost position and is then moved horizontally to a top position on the mold column for forming an upper mold.
