Since the misalignment is detected by measuring the distance to 2k, 3i, 3j, and 3k, if the measurement of 3 points 2i, 2j, 2k, 3i, 3j, and 3k is not disturbed by the jacket, cover the jacket. It can be measured even from.
- the upper and lower molds 2 and 3 that are misaligned should not be poured with a pouring machine. That is, the control device of the pouring machine controls the upper and lower molds 2 and 3 that have received the determination that the mold has shifted so as not to pour hot water. Since no hot water is poured into the upper and lower molds 2 and 3 in which mold misalignment occurs, consumption of the molten metal due to wasteful pouring can be prevented.
- the molding with the frame making machine 1 is stopped until the cause of the mold deviation is eliminated. Therefore, since it is possible to avoid the molding of the upper and lower molds 2 and 3 that cause mold misalignment, consumption of foundry sand due to unnecessary molding can be prevented.
- “stopping the molding with the frame making machine 1” may be performed without molding, and the frame forming machine 1 may be operated without molding. Alternatively, only the molding line 30 may be operated without operating the frame making machine 1.
- the upper mold 2 when it is determined that there is a misalignment as a result of the misalignment detection, it is preferable to identify and display the cause of misalignment from the misalignment situation. For example, when the upper mold 2 is displaced rearward from the lower mold 3 with respect to the mold extrusion direction (the direction of the arrow 6 in FIG. 1) of the frame making machine 1, the lower mold is moved by a mold extrusion device (not shown). It is thought that the initial speed when pushing out 3 is too fast. Further, when the upper mold 2 is displaced rearward from the lower mold 3 with respect to the direction of travel of the molding line 30 (the direction of the arrow 7 in FIG. 1), a pusher device (not shown) pushes the platen carriage 4.
- the factor can be specified by the direction of deviation between the upper mold 2 and the lower mold 3. Therefore, by displaying the identified factors, it is easy to recognize the contents to be repaired by the operator and to easily eliminate the cause of the misalignment.
- the cause of occurrence of the specified misalignment may be displayed by the display panel of the misalignment detection device 40, a specific display panel, or a control device of another device.
- the cause of misalignment when it is determined as a result of misalignment as a result of misalignment detection, it is preferable to identify the cause of misalignment from the state of misalignment and correct the operating conditions of the equipment that causes the misalignment. For example, when the upper mold 2 is displaced rearward from the lower mold 3 with respect to the mold extrusion direction (the direction of the arrow 6 in FIG. 1) of the frame making machine 1, the lower mold is moved by a mold extrusion device (not shown). It is thought that the initial speed when pushing out 3 is too fast. In this case, the initial speed of the mold extrusion apparatus is corrected as the operating condition of the equipment that becomes a factor.
- the setting of the initial speed is automatically or manually corrected so that the initial speed of the mold extruding device becomes slow. In this way, the occurrence of mold shift from the next cycle is eliminated.
- the initial speed of the pusher device is corrected as the operating condition of the equipment that becomes a factor.
- the setting of the initial speed is automatically or manually corrected so that the initial speed of the pusher device becomes slow. In this way, the occurrence of mold shift from the next cycle is eliminated.
- the die displacement caused by the frame making machine 30 or the molding line 30 for transporting the upper and lower molds 2 and 3 from the frame forming machine 1 to the pouring position It is preferable to store the absence of data as data. By recording data in this way, even if a defect is found in the product, it can be confirmed that there is no problem of misalignment during molding, and the cause can be easily investigated. Note that the data may be stored in the calculation unit 48 or a control device of another device.

Therefore, the amount of misalignment can be detected more quickly and accurately.
