Description
The present invention relates to a pressurization of a mold for casting a hollow cast product, and more particularly, to a pressurizing heating apparatus capable of heating the pressurization very easily and heating the pressurization temperature uniformly and efficiently.
As is widely known, casting refers to a molten metal, ie, a molten metal that is placed in a mold and solidified to form a metal product of a desired shape or a product thereof. The material of the mold is made of sand, metal, and the like, and molten metal is injected into the mold by gravity, pressure, centrifugal force, or the like.
When the molten metal is injected into the mold, shrinkage occurs while cooling and solidifying, and a mold is installed in the mold. Such a hot water can compensate for insufficient melt due to shrinkage to prevent the occurrence of pores or bubbles, and also prevent local deformation due to shrinkage, pressurize the molten metal in the mold to densify the structure of the casting product, and It serves to discharge the gas contained.
When casting a casting having a hollow part, such as a propeller, the molten metal in the mold starts to solidify in the hot water part exposed to the atmosphere, and in this case, casting defects such as shrinkage holes may occur in the product in which shrinkage occurs. The temperature of the hot water is controlled to maintain the hot water in the molten state until the inside of the cast is solidified. The solidification is sequentially performed from the bottom of the cast to the top. This is called directional solidification, and when directional solidification is performed, bubbles or other gases inside the casting are effectively discharged to the outside to prevent casting defects due to condensation shrinkage, thereby producing a more compact cast.
On the other hand, the method for managing the temperature of the hot water according to the prior art, there was a method for increasing the temperature of the hot water by increasing the temperature of the hot water through the additional hot water or by adding a heating material.
However, the additional pressure method had to inject the previously sprayed thermal insulation material in order to block the heat dissipation of the upper part of the molten metal. Therefore, there was a difficulty in removing the thermal insulation material remaining in the molten metal. The method is heavily polluted due to the dust and smoke generated by the input of the heating material, there is a problem that there is always a risk according to the worker working around the high temperature molten metal.
Therefore, recently, a hot water heating device for directly heating a hot water by a heating unit is disclosed in Korean Unexamined Patent Publication Nos. 10-2006-014533 and 10-2006-0016189.
