のである。[Detailed Description of the Invention] [Industrial Application Field] The present invention uses a horizontal frame extraction type mold making machine. After the table plate, which has a sensor embedded therein that detects the proximity of the lower casting, is raised so that it contacts the bottom surface of the lower casting without any gaps, a pressure plate is lowered over the upper casting mold to create a push or loosening in the upper and lower casting molds. This invention relates to a mold release device for a horizontal frame removal type mold making machine which is designed to release the mold without causing any interference.

合せした状態で鋳枠より離枠しているものである。Traditionally, in this type of horizontal flask type mold making machine, the frame removal process after mold making involves raising and lowering the upper and lower flasks that hold the pattern, removing the mold, and then lifting the molds up and down again. The flask was lowered and raised to align the molds in the flask. At the same time, a table plate was raised to a certain height from below the lower flask and the lower surface of the lower mold was held on the upper surface of the table plate. After that, the pressure plate is lowered from the upper surface of the upper mold, and the table plate is also lowered accordingly, leaving the upper and lower molds aligned and separated from the flask.

ある。However, in the above-mentioned conventional flask removal method, after the upper and lower flasks are matched, the lifting range of the table plate that rises to a certain height below the lower mold is set in advance at a stop position by a limit switch. Therefore, there is no problem if the mold thickness matches this set value, but depending on the mold thickness after molding, due to changes in the compactability value of the molding sand, changes in the properties of the mixed sand, etc. Since the temperature changes, the rise of the table plate caused by the limit switch that restricts the range of rise to a certain degree can actually cause inconvenience. In other words, if the mold thickness is thinner than the set value, a gap will be created between the upper surface of the table plate that has been raised by the set amount and the lower surface of the lower mold, and the pressure plate will be raised from the upper mold to compensate for this. If an attempt is made to lower the mold and shatter it, the gap between the lower mold and the top surface of the table plate will fall, causing the parting surfaces of the upper and lower molds to shift and cause sluggishness.On the other hand, the mold thickness will become thicker than the set value. If this happens, the table or plate will rise to the point where it pushes up the lower mold, causing a push-in that causes deformation of the mold, causing a problem in which the chamber is difficult to fracture after molding.

のである。In addition, the current solutions for such frame release methods require extremely complicated adjustment work, such as adjusting the position of the upper limit switch when the table plate rises, depending on the mold thickness during molding, which reduces molding efficiency. This is something that is hindering improvement.

るものである。The present invention was created in view of these problems, and it is necessary to prevent the above-mentioned bulging and pressing when the mold is removed, and to adjust the thickness of the mold to accurately respond to changes in mold thickness. Formed by penetrating the table plate from the bottom surface and embedding a sensor that senses the position of the bottom mold surface so that the table plate is in contact with the bottom surface of the bottom mold without any gap, and its top surface is level with the table. As a result, the table plate rises toward the bottom surface of the lower mold after the upper and lower casting flasks are aligned, and the sensor detects the position of the mold surface, making it tightly contact with the table surface without any gaps. [Function] With this structure of the present invention, when removing the mold, after removing the model, the table plate is moved from below the upper and lower flasks that have been matched. As it rises, a sensor embedded so that the upper surface is an even surface detects the position of the lower surface of the lower mold, and after rising tightly with it without any gaps, it stops, and then the upper mold is lowered from above. Since the pressure plate is lowered and the table plate is also lowered accordingly, there is no gap between the lower surface of the lower mold and the surface of the table plate unlike in the conventional frame removal method. In addition, since the lower mold is not pushed up by force, it has an extremely excellent effect of precisely crushing the mold without causing any swelling or pushing.

After molding the upper and lower molds (10x8) by blowing molding sand into them from the molding sand blowing port (3x3'), the molds (10x8) are separated once, the model that was being pressed between them is removed, and the upper molding flask (4 ) is lowered again and the table plate (7) is raised to the lower surface of the lower mold (8), resulting in the state shown in Figure 1. At this time, the table plate (7) is the upper and lower limit switch (12X13). Although it rises and falls between
Upon detection by a sensor (9) embedded in the table plate (7), the table plate (7) is raised at a groove that closely contacts the bottom surface of the lower mold (8) without any gaps and then stopped, and then the pressure plate (6) descends and the upper and lower molds (lOX
