Abstract

PURPOSE: To remove sprues readily and surely from castings by acting moment force upon the cross gate and breaking the boundary between the cross gate and sprue in the mold built in a flask after pouring.
CONSTITUTION: An elevating table 6 is risen so that its top end comes to the position slightly lower than the top end of collared rollers 3, 3 and a sprue holding member 13, etc. are also rise together with the table 6 by operating a cylinder 9. Next, a flask 5 built in with a mold 4 in which the molten steel having been poured is in a state of having solified to a certain extent is placed on the rollers 3, 3 and is transferred to right above the table 6, after which the holding member 13 is pushed in the mold 4 to support the bottom part of the sprue 12, thence the sprue 12 is sandwiched and fixed from above and below by lowering a pressing member 18. Next, the pressing member 24 is lowered into the mold 4 to break the boundary between the cross gate 23 and sprue 12. This cross gate 23 is pushed out together with the casting 29 and the greater portion of the mold 4 onto the table 6.
