Definitions

  • the present invention relates to a mold assembly, and more particularly to a centrifugal casting mold assembly.
  • casting refers to the work of making a product in a desired shape by removing the mold after solidifying by injecting a molten metal material, that is, a molten metal into a mold, and in order to efficiently proceed with such a casting operation.
  • a molten metal material that is, a molten metal into a mold
  • Each casting process can be classified into sand casting, mold casting, precision casting, etc., depending on the type of mold, and in the case of mold casting, gravity casting, low pressure casting, and/or low pressure casting, depending on how the molten metal is injected into the cavity of the mold. It can be classified into high pressure casting, high vacuum casting, centrifugal casting, etc.
  • the centrifugal casting method is a method of injecting molten metal by generating centrifugal force by rotating the mold.
  • the centrifugal casting method rotates the mold at high speed when the molten metal is injected and solidified, and is formed using this rotating centrifugal force.
  • the molten metal flows in and is distributed by the centrifugal force rotating at high speed in the mold to prevent poor fluidity and This smooth, high pressure applied to the molten metal, so the structure of the cast product is dense and there are no pores, so this method is widely used.
  • a molded article having a uniform thickness and high quality can be manufactured only when the molten metal is quickly and uniformly supplied over the entire surface of the mold and the molten metal is directional solidification inward from the mold surface.
  • the molten metal flows while rotating the mold and the casting is made using centrifugal force.
  • the molten metal is flowed into the mold by the action of gravity.
  • the mold is arranged radially along the circumference to make a flow path of the molten metal in the radial direction, and then flows into the center of the disk, and the disk is rotated and cast while pressing by centrifugal force.
  • a tube body is used to continuously move various liquids or gases, and such a tube body is manufactured to a certain standard due to various reasons such as manufacturing method or transportation.
  • the stainless flange produced by the above-described centrifugal casting method is the same casting product as the stainless flange produced by sand casting, but the elongation and tensile strength are close to the forged product, and the structure of the product is dense, and the product does not contain foreign substances. Can produce quality flanges.
  • the reason that the centrifugal casting method, which can produce such high quality products, is neglected at the production site, is that manufacturing is more difficult and productivity is lower than the sand casting method.
  • the mold is made of the material used for general metal casting, and a refractory material with a high heat-resistant temperature is installed (construction) where the molten metal falls to prevent the molten metal from falling directly into the mold, thereby preventing the mold from melting.
  • the workability is very inconvenient because the maintenance process such as repairing and replacing severely damaged refractory materials is frequent, as well as relying on manual work.
