5, when a manual handle (not shown) is connected to the end of the slider bar 350 and rotated in one direction, a pair of feed guider portions (not shown) disposed above and below the slider bar 350 330 are widened.

The angle between the pair of first folding arm portions 310 connected to the feed guider portion 330 by the hinge shafts 310a and 320a as the distance L1 between the pair of feed guider portions 330 becomes wider and the angle [theta] 11 between the pair of second folding arm portions 320 becomes large.

Accordingly, since the space between the inner surface of the first side wall 110 of the main body 100 and the first surface 210 of the plate portion 200 becomes narrow and the space of the receiving portion 101 relatively widens, Is accommodated in the accommodating portion 101 or the mold accommodated in the accommodating portion 101 is easily removed.

6, when a manual handle (not shown) is connected to the end of the slider bar 350 and rotated in the opposite direction, a pair of feed guider portions (not shown) disposed above and below the slider bar 350, (L2) between the first electrode (330) and the second electrode (330) becomes narrow.

The angle between the pair of first folding arm portions 310 connected to the feed guider portion 330 by the hinge shafts 310a and 320a as the distance L2 between the pair of feed guider portions 330 becomes narrow and the angle [theta] 22 between the pair of second folding arm portions 320 becomes small.

The space between the inner surface of the first sidewall 110 of the main body 100 and the first surface 210 of the plate portion 200 becomes wider and the space of the receiving portion 101 becomes relatively narrow, The plurality of molds can be firmly fixed by simultaneously pressing one side of the plurality of molds housed in the molds 101.

As a result, not only the spacing between the plurality of molds is uniform, but also the degree of adhesion between the molds which are successively disposed and substantially integrated together is improved, so that the tear can be prevented from leaking into gaps between the molds.

This not only improves the safety of the operator significantly, but also improves the productivity by minimizing wasted waste because it can not leak into the gap or inject into the injection port.

The operation of the dumping member 600 for performing the dumping operation by reversing the casting flask so that the molded product and the mold can be separated from the mold in the casting flask after completion of molding is as follows.

The wheel 550 of the mold car 500 is movable along the rail 700. That is, the movement of the mold car 500 is such that the mold car 500 is movable along the rail 700 by pushing or pulling the mold car 500 as the piston rod of the moving cylinder (not shown) expands and contracts.

The moved casting flask is located inside the wheel portion 610, as shown in FIGS.

At this time, the stopper portion 630 provided inside the wheel portion 610 catches the upper and side surfaces of the edge of the frame 510 of the molded car 500.

When the wheel unit 610 is rotated in one direction by the driving unit 650, the body unit 100 fixed to the wheel unit 610 is rotated together with the stopper unit 630, The molded product and the mold are separated from the mold in the main body part 100. When the wheel part 610 is rotated in the opposite direction again, the main body part 100 is re-inverted (rotated to its original position) .

In this way, the dumping operation of the casting flask is carried out by reversing and re-inverting the casting flask immediately by the rotation of the wheel 610 while the casting flask is moved into the dumping member 600, And the operation efficiency can be greatly improved as compared with the dumping operation in which the conventional casting flask is lifted up and inverted.

In addition, since the dumping operation is directly performed by the dumping member 600 without moving from the casting line to the other reverser, the continuous casting line can be more efficiently performed, and the productivity can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
