問題がある。(Prior art) A plurality of vertical frameless molds successively molded by a vertical mold making machine are successively molded in the horizontal direction, and a pouring cavity is formed at the mutually contacting portions of the molds. Methods for casting large quantities of shaped castings are known. Conventionally, in this casting method, a large number of matched molds are advanced intermittently on a guide path, and metal is poured as they move forward, and the poured molds are sequentially moved from the conveying end of the guide path to a shakeout machine. It is extruded onto another disassembly device, where the cast product and mold sand are separated. However, such a separation process necessarily involves manual work and poses safety and health problems.

16868号公報、実開昭61−200645号公報等）。 Recently, in order to solve these problems, a casting removal device has been installed near the extrusion end of the mold guide passage, and clamp claws, hanging arms, etc. are inserted into the most advanced mold on the guide passage to remove the inside of the mold. A method has been proposed in which the mold itself is extruded from a guide passage onto a disassembly device while the cast product is taken out (for example,
16868, Utility Model Application Publication No. 61-200645, etc.).

ている。 Near the conveying end of the mold guide passage 2, there is a pair of cast product lifting claws 1 oriented in the same direction as the passage 2.
1 and 11 are disposed with their tips facing the two directions of the passage. The cast product lifting claws 11, 11 are movable back and forth along the mold guide path 2,
The tips of the hanging claws 11, 11 in the advanced position are designed to be inserted into the mold 3 at the most distal end on the mold guide passage 2 to a predetermined depth.
Note that the level of the hanging claws 11, 11 is the same as that of the mold 3.
It is designed to be positioned below the runners 8, 8 for lifting the cast product in the cast product 4 cast into the connecting portion of the cast product. Further, the lengths of the hanging claws 11, 11 are determined so that a plurality of cast products 4 are suspended thereon. In addition, the hanging claws 11, 11 can be pivoted by a predetermined angle in the horizontal direction about their base ends in the retracted position, and a casting conveyor (not shown) is disposed below the pivoting stop position. The castings 4 suspended on the hanging claws 11, 11 are now designed to be transferred from the hanging claws 11, 11 to the transport conveyor.

なされる。(Function) In the device constructed as described above, the cast product lifting claws 11, 11 are set to the forward position while the damping board 1 at the tip of the mold guide passage 2 is kept horizontal. Thereafter, when the damper 1 is opened downward and the mold 3 is pushed in the direction of the arrow by one piece, the tips of the hanging claws 11, 11 are brought into the guide passage 2.
Relatively inserted below the casting product lifting runners 8, 8 in the casting product 4 which has passed through the upper most advanced mold 3 and has been cast into the joint between the mold 3 and the next mold 3. The cast product 4 is suspended on the cast product lifting claws 11, 11 via the hanging runners 8, 8, while the most advanced mold 3 has a damping board 1 opened downward. Also, since the cast product 4 is cast in the joint between the mold 3 and the next mold 3, it is separated from the next mold 3 due to its own weight and placed on a disassembly device (not shown). In this way, the cast product 4 and the mold 3 are separated.

Get out of. Thereafter, the hanging claws 11, 11 turn horizontally at a predetermined angle about their base ends, and unload the suspended castings 4 onto a casting conveyor (not shown). After unloading, the hanging claws 11, 11 are reversely rotated to their original positions and set to the forward position.

れ、生産効率が向上する。(Effects of the invention) As described above, the present invention uses a vertical frameless mold that is configured to be able to cast a runner for lifting a casting product and a runner for pushing a casting product in addition to the product section. The cast product thus cast can be easily and reliably taken out from the mold via the cast product lift runner by the pair of cast product hanger claws. Furthermore, when suspending a plurality of cast products taken out from the mold on the hanging nails, the cast products are pushed together through the runner for pushing the cast products, and the product parts do not come into contact with each other. Therefore, the pushing operation can be carried out smoothly regardless of the shape of the product. Furthermore, since the plurality of castings suspended on the hanging claws are conveyed all at once to the conveyor, the waiting time in the work of taking out the castings is greatly shortened and production efficiency is improved. .
