Specifically, the first support beam 15 and the second support beam 3 are respectively fixed to the left and right sides of the table 13 . Specifically, the moldless casting molding machine further includes a first cutter system 17 and a second cutter system 18 that are mounted on the first yaw motion system 5 and the second yaw motion system 9, respectively. Since the yaw axis motion system and the yaw axis motion system are both driven by respective driving devices, and both the first yaw motion system 5 and the second yaw motion system 9 are equipped with the rotary cutter systems 17 and 18, the moldless casting is performed. The forming machine can simultaneously process both sides of the mold (sand type) in the X-axis direction. Preferably, the rotary tool system can employ an electric spindle structure to drive the tool to achieve rotational motion. Specifically, the moldless casting molding machine further includes a machine tool shield 19 fixed around the table. As described above, the present invention has the following advantages: The processing range of the moldless casting molding machine of the present invention in the X-axis direction is greatly increased. That is, with respect to the molding machine described in the prior patent, the processing size range of the mold has been greatly increased, overcoming the problem that the conventional moldless casting molding machine cannot process a mold having a large structural size. Further, the moldless casting molding machine of the present invention can simultaneously process both sides of the mold (sand type) in the X-axis direction, thereby greatly shortening the processing time and improving the processing efficiency. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
