Cast iron pan production equipment with recirculated cooling water device and its die casting method

Abstract

The invention belongs to the casting technique filed, in particular relating to a manufacture device and die-casting method for a cast iron boiler with a cycling water cooling device. The device includes an upper mold, a lower mold and a base and is characterized in that the lower mold is made into a lower mold with a cord slot. The cycling water cooling device is connected with the base. The middle part of the base is provided with a round hole with a dimension corresponding to the cord slot of the mold. The two sides of the base are provided with ordinary holes for cooled water. The cooling section of the cycling water cooling device is arranged in the round hole of the base. The invention has the advantages that as the cycling water cooling device is adopted, the invention effectively solves the problems of slow cooling speed at the bottom part of the cast iron boiler and uneven condensing temperature for the cast iron product, leads the thicker molten iron cast by the cord slot at the bottom part of the lower mold to be simultaneously cooled with the molten iron in a whole mold cavity tool; the invention also has the advantages of uniform product condensing temperature, no air bladder and great improvement on the product quality and finished product rate.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a cast iron pot production equipment with a circulating cooling water device and a die-casting method thereof. Background technique [0002] Cast iron pan is one of the commonly used cooking utensils in our country. It has a special effect on human health, so it is widely used. Most of the methods of making cast iron pots still adopt traditional casting or die-casting methods at present. Chinese patent 91110917. X discloses a casting method and mold of a cast iron handle pan. The mold of this patent comprises a patrix and a lower mold. The bottom surface of the finished pot cast in this way is the same as the wall thickness of the whole pot, and there is no pot navel. Because the bottom surface is heated greatly during use, the bottom part of the pot is easy to burn out, and the service life is short. Consumers still hope that the bottom of the cast iron pan has a ...

AI Technical Summary

Problems solved by technology

However, with the usual die-casting equipment and methods, when the bottom of the mold cavity of the cast iron pot is thickened, due to the thick molten iron layer at the bottom, the cooling rate is slow, the condensation temperature of the product is uneven, and the bottom of the pot is prone to air holes (bubbles). Therefore, the molding quality Poor, very low yield
