Embodiment Construction

[0050] One embodiment of these inventions is now explained in detail based on figures. As in FIG. 1, a main body A of a molding apparatus comprises:

[0051] a cope flask 2 and a drag flask 3, which can hold therebetween a match plate 1, having patterns 1a, 1a, at both its sides,

[0052] an upper squeezing member 4, which is insertable into the opening positioned on the opposite side of the cope flask 2 from the match plate 1,

[0053] a filling frame 6 perpendicularly fixed to a base 5, and

[0054] a lower squeezing member 7, which is insertable in the filling frame 6, wherein the lower squeezing member 7 is disposed so that its pressurizing surface faces the horizontal direction.

[0055]FIG. 1 shows the main body A of the molding apparatus at the initial position. In this stage, the match plate 1, the cope flask 2, the drag flask 3, and the upper squeezing member 4 are disposed at the horizontal position, and the pressurizing surface of the upper squeezing member 4 faces perpendicularly ...

Abstract

These inventions provide a core-setting apparatus and a method for setting the core in a lower mold used for a molding apparatus, wherein the core-setting apparatus has a simple structure and can maintain the core in the mold in a highly accurate position. The inventions consist of: the core-setting apparatus to set a core in the lower mold while the upper and the lower mold and a match plate are separated from each other after molding the upper and lower mold that comprises: a handling tool having a holding means and a rotatable rod, wherein the handling tool is rotatably supported by the rod, a carrier for transferring the handling tool, wherein the carrier supports the rotatable rod and is moved to or from the location above the lower mold, and an actuator for lowering and lifting the cope flask together with the carrier and the handling tool which are located above the drag flask, wherein the actuator is mounted on the main body of the molding apparatus.

Description

TECHNICAL FIELD [0001] These inventions relate to a core-setting apparatus used for a flaskless molding apparatus for producing a pair of an upper and a lower mold, which molding apparatus uses a match plate, and a method for setting a core. BACKGROUND OF THE INVENTIONS [0002] Conventionally, as one core-setting apparatus that is used for a flaskless molding apparatus for producing a pair of an upper and a lower mold by using a match plate, there is a type of apparatus that comprises the following: [0003] after a drag flask is placed outside the apparatus by moving it forward from the apparatus, wherein the drag flask is movable forward and backward, [0004] a core-setting apparatus sets a core in a lower mold in the drag flask, wherein the core-setting apparatus is disposed above the drag flask. (See Patent Document 1.) [0005] Patent Document 1: Pamphlet of International Patent Laid-open Publication No. WO 02 / 43901 (See FIG. 3.) DISCLOSURES OF INVENTIONS [0006] However, for the inve...
