Description

Technical Field

[0001] The utility model relates to the technical field of cast iron pots, and in particular to a rapid cooling mechanism for producing cast iron pot blanks. Background Art

[0002] A cast iron pot is a pot made of an iron-carbon alloy with a carbon content of more than 2%. The carbon content of industrial cast iron is generally 2% to 4%. Carbon exists in cast iron mostly in the form of graphite, and sometimes in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% silicon, as well as phosphorus, sulfur and other elements. Cast iron pots are made by casting gray iron melts using a mold. Cast iron pots have uniform heat transfer and are not prone to sticking. At the same time, cast iron pots can supplement the necessary iron element for the human body to prevent iron deficiency anemia.

[0003] In the actual production process, cast iron pots are often die-cast. During die-casting, molten iron is injected into the lower mold, and then the upper mold squeezes the lower mold downward so that the iron pot is evenly formed on the inner wall of the lower mold. This method is easy to operate and the surface of the cast iron pot is relatively smooth.

[0004] However, after the actual die-casting of the cast iron pot, the temperature of the cast iron pot blank is relatively high, so it is easy to produce clamping deformation when the pot blank is clamped out of the lower mold. If natural cooling is adopted, the production efficiency of the cast iron pot will obviously decrease. Cooling treatment is required to speed up the cooling speed and ensure that no deformation occurs. Utility Model Content
