This is compressed to a predetermined strength to form a mold, then the pattern plate is removed, and finally the mold is extruded from the flask. In order to smoothly extrude the mold, the flask used for making the frameless mold has a slightly larger internal dimension along the mold removal direction, and when the pattern plate is removed, the mold is Usually, some kind of stopper mechanism is provided on the side wall of the flask to prevent it from slipping out of the flask while still attached to the pattern plate.

たものなどがある。 Conventionally, the stopper has a configuration in which, for example, a through hole is bored in the side wall of the flask, a protrusion that can slide through the through hole is provided, and one end of the protrusion is connected to a cylinder. None, the other end of the protrusion is made to protrude from the inner wall of the mold during molding, and when the pattern plate is removed after molding, the resistance of the protrusion prevents the mold from falling out, and the mold During extrusion, the protrusions are retracted from the inner wall of the flask so that the mold can be extruded smoothly, or the protrusions are simply fixed to the inner wall of the flask.

た。 However, the former mechanism has the disadvantage that it has a complicated structure and is expensive to install, while the latter mechanism has a simple structure and can be installed at low cost, but it cannot adjust the insertion and removal of the protrusion, so if the degree of protrusion is too small. When removing the pattern plate, there was a risk that the mold would fall out of the flask along with the pattern plate, making it impossible to remove the mold.On the other hand, if the degree of protrusion was too large, the mold could not be pushed out of the flask.

のである。 The present invention was developed in view of the above circumstances, and is a casting flask for frameless mold making that is capable of adjusting the insertion and removal of protrusions and is equipped with a stopper mechanism that has a simple structure and can be installed at low cost. It provides:

には押し出し板７が取り付けられている。 Hereinafter, the present invention will be described in detail based on an embodiment. In FIG. 1, a pattern plate 1 is removably mounted on a lifting table (not shown), and the frame size is slightly enlarged toward the bottom of the drawing. Molding sand is put into a space defined by the tapered flask 2 and is compressed to a predetermined strength to form a mold 3. Further, arms 4, 4a are provided on both sides of the flask 2 and can be opened/closed and raised/lowered by cylinders (not shown). Further, above the flask 2, a cylinder 5 attached to a support member (not shown) is disposed facing downward, and a push-out plate 7 is attached to the tip of a piston rod 6 of the cylinder 5.

ト８を固定している。 A plurality of screw holes are drilled through the wall at predetermined positions in the side wall of the flask 2, and bolts 8 are inserted into the screw holes so that the tips of the bolts are inserted from the inner wall surface of the flask 2. They are screwed together so that they protrude slightly. Note that the degree of protrusion of the bolt 8 is adjusted to about 1 m/m in the embodiment. The bolt 8 has a nut 9
is tightly screwed onto the outer wall of the flask 2 to fix the bolt 8.

る。 In the structure configured as described above, the arms 4, 4a are first actuated by a cylinder (not shown).
is closed so that the claws of the arms 4, 4a support the upper jaw of the flask 2. Next, a lifting table (not shown) is lowered to separate the pattern plate 1 from the flask 2 and mold 3 (see FIG. 2). At this time, the mold 3 does not come out of the flask 2 due to the resistance force of the bolts 8 protruding from the inner wall surface of the flask 2, and only the pattern plate 1 is separated.

う。 Next, after placing the surface plate 10 on a lift table (not shown), the table is raised, and the surface plate 10
is applied to the lower edge of the casting flask 2. At the same time, flask 2
The upper cylinder 5 is operated, the rod 6 is extended, and the extrusion plate 7 is applied to the back surface of the mold 3.

１０上に載置された形で残る（第３図参照）。 In this state, when a cylinder (not shown) is operated and the flask 2 is raised via the arms 4, 4a, the cylinder's support is greater than the resistance of the bolts 8 protruding from the inner wall surface of the flask 2. Since the upper force exceeds the upper force, only the flask 2 rises and the mold 3 remains placed on the surface plate 10 (see Fig. 3).

る。 As is clear from the above description, the present invention involves drilling a plurality of screw holes through the side wall of a tapered flask, screwing bolts into the screw holes, and ensuring that the tip of the bolt is inserted into the flask. It is made to be able to protrude from the inner wall surface to an arbitrary extent. Therefore, by appropriately adjusting the degree of protrusion of the bolts, it is possible to prevent the mold from falling out of the tapered flask together with the pattern plate when the mold is removed, and at the same time, to easily separate the mold from the flask when the mold is removed. be able to. Moreover, since the mechanism is simple, the installation cost is low.
