[0037] Working principle and process:

[0038] The staff first places the metal mold set 11 on the conveyor belt 19. Under the action of the anti-sliding block 20, the metal mold set 11 can be effectively prevented from sliding during the conveying process, so that it cannot be accurately placed on the fixed platform 10. At this time, the positioning block 21 fixedly connected to the top of the fixed platform 10 will be embedded in the positioning groove 22 opened at the bottom of the metal mold set 11 to fix the metal mold set 11 to prevent it from moving during the rotation process. Then the pouring device 26 will pour the metal mold at the bottom. After the pouring is completed, the servo motor 2 fixedly connected to the working box 1 will drive The main shaft 3 is driven to rotate. Under the action of the bearing 18, the friction coefficient between the main shaft 3 and the support seat 17 is reduced, the rotation accuracy of the main shaft 3 is ensured, and energy consumption is reduced. The main shaft 3 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 5 to rotate, the second bevel gear 5 drives the connecting shaft 6 to rotate, the connecting shaft 6 drives the meniscus 7 to rotate, the meniscus 7 drives the lever 8 to rotate, the lever 8 slides in the through groove provided in the limit card plate 9, and drives the limit card plate 9 to rotate ninety degrees, so that the pouring device 26 can pour the next metal mold, realize continuous pouring, and improve work efficiency. The limit card plate 9 drives the fixed platform 10 to rotate, and the fixed platform 10 drives the metal mold group 11 to rotate ninety degrees. When one metal mold is poured, it rotates ninety degrees again to pour the next metal mold, thereby realizing continuous pouring during the casting process, improving the pouring work efficiency, increasing the production efficiency, and increasing the profit. When the four metal molds on the metal mold group 11 are poured, the electric push rod 13 fixedly connected to the top of the support base 12 will push the push plate 14, and the push plate 14 squeezes the spring 15. The spring 15 applies elastic force to the squeezing plate 16, and the squeezing plate 16 pushes the metal mold group 11. Under the action of the buffer plate 25, the damage of the extrusion plate 16 to the metal mold group 11 can be reduced, and its service life can be increased. The extrusion plate 16 pushes the metal mold group 11 onto the conveyor belt 19, and there is no need for the staff to manually remove it, thereby improving work efficiency. Under the action of the spring 15, it can also prevent the metal mold group 11 from being damaged by excessive thrust, thereby reducing losses and increasing its service life. When the push plate 14 needs to be replaced after being used for a period of time, the push plate 14 is pressed to make the limit block 24 slide inside the limit groove 23, and then it is pulled out for replacement. The limit block 24 plays a role of limiting the push plate 14.
