[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] A specific embodiment of this utility model provides an automated V-method production line for extra-large shuttle-type molding rings, combined with an appendix. Figure 1 and 2 As shown, the production bus includes a molding ring 1, a box-turning machine 2, a box-closing support 3, a transport mechanism, a pouring and cooling mechanism, a sand-falling mechanism, and a vacuum mechanism. The molding ring 1 is located on one side of the box-turning machine 2 and the box-closing support 3, which are symmetrically arranged. The pouring and cooling mechanism is located on the other side of the box-turning machine 2. The transport mechanism connects the molding ring 1, the box-turning machine 2, the box-closing support 3, the pouring and cooling mechanism, the sand-falling mechanism, and the vacuum mechanism. The molding ring 1 adopts a multi-model online, upper box model, and lower box model alternating molding operation mode. The models can be changed online, which greatly improves work efficiency. The manual operation station and model changing station of the production bus are all located outside the molding ring, which is an open environment, convenient for operation, and also ensures the transfer of sand cores and the passage of personnel for the production bus.

[0025] The production bus pouring area is located near the electric furnace melting zone, facilitating the transfer of molten iron from the electric furnace to the pouring machine; the unpacking area is located near the casting cooling and cleaning section, facilitating the automatic transfer of castings to the cooling section.

[0026] The production line's film coating area, unpacking area, and model spraying area adopt a fully enclosed dust removal method to ensure that smoke and dust do not leak out; dust removal interfaces are set up at all transfer points for sand addition and vibration and sand treatment; and sand hoppers are set up under the sand addition section of the molding ring, the mold release station, and the box turning machine to improve the working environment.

[0027] The production line equipment is equipped with relevant data acquisition interfaces, and equipment status data, process setting parameters and operation data, energy consumption information, etc. can all be exchanged with the factory information system to meet the requirements of a modern digital factory.

[0028] All vacuum pumps in the production line are housed in a dedicated vacuum pump room to minimize noise pollution. The vacuum system uses water ring vacuum pumps, all of which are frequency converter controlled.

[0029] Within modeling circle 1, a work method of alternating arrangement of lower and upper box models is adopted, with the lower box modeling starting first. The workflow for the lower box model is as follows:

[0030] The lower mold is automatically covered with film (the mold is vacuumed), the paint is sprayed and dried by the paint drying device 20, the sand box is placed by the second suction box transfer car 21, the sand box is added and vibrated to compact the sand, and the back film is manually applied by the first suction box transfer car 17, the back sand is scraped and the back film is applied (the sand box is vacuumed and the model is vacuumed). The mold lifting device 18 automatically lifts the mold, the sand box is lifted and placed on the box turning machine 2, and the molded model is placed on the conveyor roller 25 and then transported to the film covering section to start the next work cycle.

[0031] The workflow for the upper box model is as follows:

[0032] The upper mold is automatically covered with film (the mold is vacuumed), the paint is sprayed and dried by the paint drying device 20, the sand box is placed by the second suction box transfer car 21, the sand box is added and vibrated to compact the sand at the sand adding station, and the back film is manually applied by the first suction box transfer car 17, the back sand is scraped and the back film is applied (the sand box is vacuumed and the model is vacuumed). The mold lifting device 18 automatically lifts the mold, the sand box is lifted and placed on the box turning machine 2, and the molded model is placed on the conveyor roller 25 and then transported to the film covering section to start the next work cycle.

[0033] The lower sand box undergoes shaping, core removal, and debris removal on the sand box turning machine → it is manually hoisted to the sand box assembly support for assembly → the upper sand box undergoes shaping, core removal, and debris removal on the sand box turning machine → it is manually hoisted to the sand box assembly support for assembly → the assembled sand box is manually lifted and placed at the 6 stations in the front section of the cooling channel → the sand box is pushed forward by push cylinders and buffer cylinders, and tilting frames 6 are installed on the pouring line 7 and cooling line 10 → the transfer vehicles at both ends transport the sand box from the cooling section to the pouring section → the sand box is poured... After the pouring station tilts, the sand box is pushed forward by the push cylinder and the buffer cylinder. The transfer cars at both ends transport the sand box from the pouring section to the cooling section. After cooling for a period of time, the sand box is manually hoisted to the sand removal car. The sand removal car transports the sand box to the unpacking station. The casting is manually hoisted onto the casting turning machine to clean the casting and the pallet. The pallet is transported back to the original station by the sand removal car. The pallet is manually hoisted to the cooling section. The cooling section begins to receive the sand box after it has been closed and begins the next cycle.

[0034] After opening the box, the empty box is manually hoisted to the empty box turning device for sand box cleaning. The empty sand box is then manually hoisted to the empty box return trolley and transported to the vicinity of the modeling area, where it is manually hoisted for use in the attraction box to house the empty box.

[0035] After the sand is unpacked, it is collected from the sand collection hopper to the screw feeder → vibrating conveyor screen → fluidized bed → magnetic separator → elevator → pneumatic conveyor trough → molding sand hopper.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
