because the strength of the white mold is lower and careful operation is needed when the mold is just removed after the mold is cooled and demoulded by water in the molding process of the white mold of the mold-free casting white area process, a certain time is needed for manual mold taking, so that the non-working time of the molding machine is longer, and the working efficiency of the molding machine is reduced; the invention thus provides for the provision of a mobile module 9; firstly, a controller controls a hydraulic cylinder 8 to push an upper die 6 to move downwards to be matched with a lower die 4 on a first sliding plate 91, and then cold water is introduced to cool and demold after feeding, die locking and heating; then the controller controls the hydraulic cylinder 8 to drive the upper die 6 to move upwards to be separated from the lower die 4 on the first sliding plate 91; then the controller controls the first electric push rod 94 to drive the connecting column 95 and the second sliding plate 92 to move towards one end of the first electric push rod 94 along the first sliding groove 93 by driving the first sliding plate 91, so that the position of the lower die 4 on the second sliding plate 92 corresponds to that of the upper die 6, the lower die 4 on the second sliding plate 92 and the upper die 6 are combined to form a white die, and meanwhile the white die on the first sliding plate 91 is manually removed; after the demolding of the lower die 4 and the upper die 6 on the second sliding plate 92 is finished, the controller controls the first electric push rod 94 to push the connecting column 95 and the second sliding plate 92 to move along the first sliding groove 93 to the end far away from the first electric push rod 94 by pushing the first sliding plate 91, so that the position of the lower die 4 and the position of the upper die 6 on the first sliding plate 91 correspond to each other, and the controller reciprocates; according to the invention, as the first sliding plate 91, the second sliding plate 92 and the two lower dies 4 are arranged, the first electric push rod 94 drives the two lower dies 4 to move back and forth, so that the working time of the forming machine is prolonged and the working efficiency of the forming machine is improved as the working time of the forming machine is not delayed in the process of manually taking out the dies while the white dies are not damaged; in addition, as the lower die 4 needs to be dried after being cooled and demoulded by cold water, the next white die forming process is prevented from being influenced, the surface of the white die is defective, the time occupied by drying and preheating the die is reduced, and the working efficiency of the forming machine is also reduced; the invention drives the lower die 4 on the second sliding plate 92 to correspond to the upper die 6 in position through the first electric push rod 94, and the first sliding plate 91 also corresponds to the position of the drying plate 104 close to the first electric push rod 94; manually removing the white mold from the lower mold 4 on the first slide plate 91; the controller controls the second electric push rod 101 to drive the pushing plate 102 to drive the third support column 103 to move downwards, so that the third support column 103 drives the drying plate 104 and the infrared drying lamp 105 to move downwards, and the lower die 4 on the first sliding plate 91 is dried and preheated; after the demolding of the lower die 4 on the second sliding plate 92 is finished, the first sliding plate 91 moves to the corresponding position of the upper die 6, and the infrared drying lamp 105 on the drying plate 104 far away from the first electric push rod 94 dries and preheats the lower die 4 on the second sliding plate 92, so that the process is repeated; the drying and preheating process is also transferred to the manual demoulding process, so that the drying and preheating time does not influence the working process of the forming machine, and the working efficiency of the forming machine is further improved; because the invention is provided with the scraping plate 11 and the ash leakage port 12; in the process that the first electric push rod 94 drives the first sliding plate 91 and the second sliding plate 92 to move back and forth along the first sliding groove 93, the scraping plates 11 at the two ends of the first sliding plate 91 and the second sliding plate 92 scrape dust impurities in the first sliding groove 93 into the ash leakage hole 12 and are discharged through the ash leakage hole 12, so that the impurities in the first sliding groove 93 cannot influence the moving process of the first sliding plate 91 and the second sliding plate 92, and the working effect of the forming machine is improved; because the first damping spring 13 and the second damping spring 14 are arranged, when the first electric push rod 94 drives the first sliding plate 91 or the second sliding plate 92 to move to the two ends of the first sliding groove 93, the first sliding plate 91 and the second sliding plate 92 are contacted with the first damping spring 13 first, so that the impact of the first sliding plate 91 and the second sliding plate 92 on the supporting table 3 is slowed down; because the second damping spring 14 is arranged on the connecting column 95 between the first sliding plate 91 and the second sliding plate 92, when the first sliding plate 91 or the second sliding plate 92 moves to the end part of the first sliding groove 93 to impact the supporting table 3, the second damping spring 14 slows down the stress of the connecting column 95, and prolongs the service life of the forming machine; therefore, when the second electric push rod 101 drives the drying plate 104 to move downwards to be close to the lower die 4, the controller controls the third electric push rod 17 to push the sliding block 16 to slide along the second sliding groove 15, so that the sliding block 16 drives the infrared drying lamp 105 to slide along the second sliding groove 15, the infrared drying lamp 105 enables the drying and preheating of the lower die 4 to be more uniform, the drying and preheating effects are better, and the working effect of the forming machine is enhanced; because the water absorbing cloth 18 is arranged, when the slide block 16 drives the infrared drying lamp 105 to move along the outer surface of the lower die 4 for drying, the water absorbing cloth 18 can dry water drops left on the lower die 4, so that the drying is faster, and meanwhile, the water absorbing cloth 18 can also erase impurities on the lower die 4, thereby ensuring the next white die forming effect; the working temperature of the infrared drying lamp 105 is about 120 ℃, and the highest temperature tolerance of aluminum silicate cotton can reach 1100 ℃, so that the infrared drying lamp 105 can dry the water absorbing cloth 18 while drying the lower die 4; further enhancing the working effect of the forming machine.
