By setting up a rapid cooling mechanism, not only can the cooling water tank be filled with cooling water, but also the metal casting can be quickly cooled by water cooling, and at the same time, the first heat sink inside the supporting bottom plate and the second heat sink inside the bottom mold bottom plate can be used to absorb heat, and the first heat sink can be quickly cooled by the cooling fan and the ventilation heat dissipation groove, and the metal casting can be fully cooled by air cooling, water cooling and heat sink, so as to improve the heat dissipation effect of the metal casting, and the bottom mold bottom plate and the bottom mold body are placed on the supporting bottom plate, and the clamping rotating arm is rotated around the bottom rotating support by pressing the bottom mold bottom plate and under the action of the first inclined surface and the clamping hook, and when the clamping hook is engaged with the fixed card slot inside the bottom mold bottom plate, the bottom mold bottom plate is fixed, and when the bottom mold bottom plate is taken, the first protrusion can be connected with the second protrusion, so that the first protrusion drives the clamping connecting rod and the clamping sliding rod to slide inside the supporting bottom plate, and at the same time, the clamping slide squeezes the clamping spring.

[0023] Working principle: Before using this kind of pouring equipment for metal castings that can be cooled quickly, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.10As shown, first, the cooling water tank 101 is filled with cooling water, and the metal casting is quickly cooled by water cooling. At the same time, the first heat sink 104 inside the supporting base plate 102 and the second heat sink 121 inside the bottom mold base plate 119 are used to absorb heat, and the first heat sink 104 is quickly cooled by the cooling fan 136 and the ventilation heat dissipation groove 103. The metal casting is fully cooled by air cooling, water cooling and heat sinks to improve the heat dissipation effect of the metal casting, and the bottom mold base plate 119 and the bottom mold body 122 are placed on the supporting base plate 102. By pressing the bottom mold base plate 119 and under the action of the first inclined surface 117 and the clamping hook 118, the clamping rotating arm 116 is rotated around the bottom rotating support 110. When the clamping hook 118 is engaged with the fixed slot 120 inside the bottom mold base plate 119, the bottom mold base plate 119 is fixed.

[0024] Secondly, the mold closing motor 204 is used to drive the sprocket drive assembly 205 and the mold closing threaded rod 206 to rotate, so that the mold closing threaded sleeve 207 and the mold closing sliding sleeve 209 drive the mold closing lifting plate 208 and the top mold body 213 to move up and down, so as to realize the mold closing of the top mold body 213 and the bottom mold body 122. At the same time, the pouring hole 211 is used to pour the metal casting. After the top mold body 213 and the bottom mold body 122 are molded, the top mold body 213 continues to move downward, so that the top mold body 213 drives the bottom mold body 122 to descend. When the outer edge of the mold closing connecting rod 215 is aligned with the unlocking rotation When the movable plate 134 contacts, the elastic force of the locking spring 131 is utilized to make the unlocking rotating plate 134 fit with the mold closing connecting rod 215. When the mold closing connecting rod 215 contacts the supporting bottom plate 102, the top mold body 213 and the bottom mold body 122 are just molded together. The first heat sink 104 is quickly cooled by the cooling fan 136 and the ventilation and heat dissipation groove 103. The top mold body 213 and the bottom mold body 122 continue to descend so that the cast metal casting can contact the cooling water of the cooling water tank 101, thereby realizing water cooling and improving the cooling effect of the metal casting.

[0025] Finally, after cooling, the top mold body 213 and the bottom mold body 122 are lifted and lowered, and the water on the surfaces of the top mold body 213 and the bottom mold body 122 can be quickly dried by the cooling fan 136. At the same time, when the mold closing connecting rod 215 is separated from the unlocking rotating plate 134, the mold closing connecting rod 215 is pushed away, thereby realizing the separation of the mold closing connecting rod 215 and the supporting bottom plate 102, and continuing to rise to realize the separation of the top mold body 213 and the bottom mold body 122. When the first protrusion 109 and the second protrusion 137 are closely connected, the first protrusion 109 drives the clamping connecting rod 108 and the clamping sliding rod 107 to slide inside the supporting bottom plate 102, and at the same time, the clamping slide block 106 squeezes the clamping spring 105, and under the action of the bottom rotating support 110, the clamping rotating arm 116 rotates, and when the clamping hook 118 is separated from the fixed slot 120, the bottom mold bottom plate 119 and the bottom mold body 122 can be quickly taken away.
