Example Embodiment
[0029] Example 1
[0030] In the actual process, when vertical sand molds are poured in series, liquid metal is first injected into the cast iron ladle, and the liquid metal is injected into the cast iron ladle that has a certain height with the sand mold. The cast iron ladle is passed and poured. The series connection of the channel and the sand mold realizes the communication between the sand mold and the cast iron ladle. The setting of the pouring ladle is higher than the height of the sand mold to ensure that there is a certain height difference between the two, so that a certain pressure is formed when the liquid metal is poured through the pouring ladle to accelerate the flow rate. After the liquid metal is poured into the ladle, the ladle must be poured to press the liquid metal into the cavity in the sand mold through the runner. The most central sand mold is connected in series with the vertical sand mold through the cast iron ladle. The liquid metal is directly presse...

[0033] In the actual process, when vertical sand molds are poured in series, liquid metal is first injected into the cast iron ladle, and the liquid metal is injected into the cast iron ladle that has a certain height with the sand mold. The cast iron ladle is passed and poured. The series connection of the channel and the sand mold realizes the communication between the sand mold and the cast iron ladle. The setting of the pouring ladle is higher than the height of the sand mold to ensure that there is a certain height difference between the two, so that a certain pressure is formed when the liquid metal is poured through the pouring ladle to accelerate the flow rate. After the liquid metal is injected into the cast iron ladle, the liquid metal in the cast iron ladle is pressed into the sand mold, and the liquid metal is pressed into the cavity through the runner. A sprue is lengthened on the upper water riser of the vertical sand mold, a water riser is arran...

[0034] Example 3
[0035] In the actual process, when vertical sand molds are poured in series, liquid metal is first injected into the cast iron ladle, and the liquid metal is injected into the cast iron ladle that has a certain height with the sand mold. The cast iron ladle is passed and poured. The series connection of the channel and the sand mold realizes the communication between the sand mold and the cast iron ladle. The setting of the pouring ladle is higher than the height of the sand mold to ensure that there is a certain height difference between the two, so that a certain pressure is formed when the liquid metal is poured through the pouring ladle to accelerate the flow rate. After the liquid metal is injected into the pouring ladle, the outlet of the lower part of the valve of the pouring ladle is directly connected to the vertical runner under the vertical sand mold. The vertical runner anastomosis connecting device at the lower part of the cast iron ladle is separ...
