Description

[0003] Deficiencies of the prior art: When the existing steel processing equipment is casting, there will always be sand holes. Sand holes are defects on the surface or inside of the casting caused by the reaction between the mold sand and the molten metal or the loosening of the mold sand grains. The reasons for causing sand holes may be that the quality of the mold sand is poor, or the connection between the mold sands is not tight enough, resulting in a chemical reaction between the mold sand and the molten metal, generating gas; or the mold design is unreasonable and fails to effectively discharge the gas; and when the metal cools and solidifies, cracks will occur in the steel due to uneven cooling.

[0014] 2. The present invention is provided with a watering mechanism, which helps to ensure uniform cooling of the surface of the casting, avoiding the generation of thermal cracks or stress concentration due to the too rapid drop of the local temperature, thereby improving the quality of the casting; due to the large temperature difference during the casting process, uneven cooling may lead to the generation of thermal cracks. By uniformly watering, the temperature difference can be effectively reduced, reducing thermal cracks and other defects caused by temperature fluctuations; by controlling the cooling rate, uniform watering can reduce the surface roughness, make the surface of the casting smoother, reduce the occurrence of surface defects, and reduce the difficulty and cost of post-processing; uniform cooling can promote the uniform growth of the grains inside the casting, making its grain structure more fine, and further improving the mechanical properties of the casting, including strength, toughness, etc.; uniform watering can accelerate the cooling rate of the casting, thereby shortening the cooling time of the casting, improving the production efficiency, and rapid cooling can also reduce the waiting time, thereby increasing the overall throughput of the production line.

[0026] Working principle of the present invention: When casting heat-resistant and wear-resistant steel, due to the loosening of the sand grains inside the lower die 402 and the upper die 401, sand holes appear in the formed steel. Therefore, it is necessary to compact the sand grains outside the mold. After a certain amount of sand grains are placed at the bottom of the lower die 402, the moving mechanism 2 is placed on the top of the lower die 402, and the reciprocating motor 205 is started to drive the rotating shaft 206 to rotate. The fixed ring 203 rotates with it and moves the bearing plate 101 to the inside of the fixed frame 202. The telescopic rod 204 is started to place the bearing plate 101 inside the lower die 402 to contact the sand grains and compress them. The gaps between the sand grains are reduced by the action of the grinding hammer 104. There is also a spring 106 at the top of the grinding hammer 104 to buffer it, preventing the grinding hammer 104 from being too hard and causing larger gaps between the sand grains.

[0027] After the grinding hammer 104 hammers, the reciprocating motor 205 is started to rotate the rotating shaft 206 to exchange the positions of the bearing plate 101 and the leveling plate 102. The sand pit affected by the grinding hammer 104 is filled and leveled by the leveling plate 102 and the pressing pattern 103 for subsequent mold placement. The same is true for the upper die 401. When the overall shaping is completed, the water pump 303 can be started to moisten the inside of the upper die 401 and the lower die 402 through the water pipe 301 and the spraying pipe 304, making the internal sealing better. Moreover, when the sand grains are in a wet state, the cast steel can be cooled better and there will be no uneven cooling. The water sprayed from the spraying pipe 304 into the upper die 401 and the lower die 402 is finally recycled through the recovery pipe 307 at the bottom of the lower die 402 by the water pump 303 and can be reused, thus realizing water circulation and preventing waste of resources.
