Abstract

PURPOSE:To execute surer carrying in and out of a casting mold by providing U-shaped grooves to a molding board, disposing rails liftably thereto and providing liftable extension rails and fork carriages to both ends of the rails. CONSTITUTION:The rails 11 are provided in a pair of the U-shaped grooves penetrated through the molding board 3 to be imposed with the casting mold. The rails 18, 18a are respectively disposed onto the extension lines at both ends thereof and further the fork carriages 21, 21a which move onto and out of the molding board 3 are installed on the molding board via the rails 11, 18, 18a. The sand mold 25 on a table 16 is transferred onto the molding board 3 by lifting of the rails 11, 18 and the carriage 21 and after a keep plate 7 is lowered, the low-pressure casting is executed. The casting mold 25 after the casting is ejected by the carriage 21a on the opposite side and the lifting of the rails 18a, 11. Since the casting mold 25 is smoothly put onto and out of the molding board 3 by the rails 11, 18, 18a, the sure carrying in and out of the sand mold 25 which is liable to break are executed.

(Effects of the Invention) As is clear from the above description, the present invention provides U-shaped grooves on the left and right sides of the surface plate in a low-pressure casting machine that is composed of a holding furnace and a surface plate for placing a mold equipped with a stalk pipe. A rail is installed in the V-shaped groove so as to be movable up and down, and loading and unloading rails extending in the direction of extension of the rail are installed on the outside of both ends of the rail so that the rail can be moved up and down. Since the construction is such that Hawk carts that can move in and out of the U-shaped groove are arranged on each of the loading and unloading rails so as to be movable back and forth to the surface plate position, damage can be prevented. Even sand molds whose size is frequently changed and whose outer walls do not have sufficient accuracy can be reliably moved to the surface plate position of the low-pressure casting machine using the carrying hawk cart, and the molds have already been poured. It is now possible to reliably scoop up and transport 8 from the surface plate using a hawk cart for transport, which was considered to be a problem with low-pressure casting using sand molds.
It has the excellent effect of being able to resolve all issues.
