補助装置も従来よりあった。2. Description of the Related Art After squeezing a mold with a mold making machine, there is an operation of releasing a pattern plate from the mold. In this operation, when the pattern plate was separated from the mold, the pattern plate was temporarily suspended from the mold, and then dropped and chipped. In order to prevent this problem, a method of attaching a vibrator to a casting frame or a pattern plate and separating the mold and the pattern plate using vibration generated by the vibrator has been conventionally performed. There has also been a die-cutting assisting device in which a die-cutting pin operated by a spring is attached to each corner of a casting frame so that the die-cutting pin pulls out the pattern plate when releasing the mold.

抜き補助装置を提供することを目的とする。However, the vibrator assists in the removal of the mold because the vibration and noise are intense, which significantly lowers the working environment. Further, in the die-cutting assist device including the spring-type die-cutting pins, the pressure of the spring at each corner is different, and the pattern plate cannot be evenly extracted. For this reason, inconveniences such as inclination of the pattern plate occur, which is a cause of chipping of the mold. The present invention has been made in order to solve the above problems, particularly without vibration and noise when releasing the upper mold and the pattern plate in a frame molding type molding machine of upper and lower mold simultaneous molding, An object of the present invention is to provide a die-cutting assisting device that does not cause chipping of a mold.

Reference numeral 1 denotes an air cylinder, which is fixed downward to each corner of the lower flange 2A of the upper flask 2. The piston rod 1A of the air cylinder 1 can be protruded and retracted from the lower surface of the lower flange 2A (see the dotted line).
Each of the air cylinders 1 is connected to an external air supply source (not shown) by an air pipe via a solenoid valve 3 and a pressure reducing valve 4. 5 is an upper mold, 6 is a pattern plate,
7 is a lower casting frame.

る。The process of releasing the upper mold 5 and the pattern plate 6 from the mold using the above-configured assisting device will be described below. In FIG. 1, in a state where the upper casting flask 2, the pattern plate 6 and the lower casting flask 7 are overlapped, the air regulated by the pressure reducing valve 4 is supplied to each air cylinder 1 by the operation of the solenoid valve 3.
And each piston rod 1A moves forward. While the tip of each piston rod 1A uniformly presses the pattern plate 6 downward at the same pressure, the upper mold 5 moves up together with the upper molding frame 2 to release the mold 5 and the pattern plate 6.

た不具合はなくなる。As is apparent from the above description, the die-cutting assist device according to the present invention uses an air cylinder.
It does not generate vibration or noise as when using a vibrator. Further, since a plurality of air cylinders are driven at the same pressure by adjusting the air pressure by the pressure reducing valve, the pattern can be evenly extracted from the mold, unlike the spring-type mold release pin. Therefore, the problem that the mold is chipped is eliminated.
