Size-variable casting mold

Abstract

The present invention provides a size-variable casting mold, which includes a pair of fixed sides positioned such that the fixed sides face each other at a distance from each other; and a pair of movable sides which is positioned between the fixed sides such that the movable sides may move in the state in which the both end sections thereof are in contact with the fixed sides, and has concave portions which are respectively indented on the both end sections, wherein molten metal is injected between the fixed sides and the movable sides. The size-variable casting mold as above prevents damage to the fixed sides due to friction between the fixed sides and the movable sides and prevents the deep and large expansion of damage even though the damage is generated to the fixed sides, so as to extend the lifespan of the mold and the replacement period thereof.

Description

technical field [0001] The present invention relates to a casting mold for continuously producing castings by injecting molten metal, and more specifically, to a variable-size casting mold capable of producing castings of various sizes by changing the size. Background technique [0002] The shape of a casting formed by casting is determined by the shape of the casting mold. However, casting molds are usually fixed to a certain size. Therefore, there is a disadvantage that in order to manufacture castings of other sizes, it is necessary to temporarily stop the casting operation and prepare a new casting mold to manufacture castings. [0003] In addition, a size-variable casting mold that can change the size of the casting mold is produced, so that castings of various sizes can be produced without interrupting the casting operation. The variable size casting mold includes a pair of fixed sides facing each other and a pair of floating sides facing each other and being able to...

Therefore, there is a disadvantage that in order to make castings of other sizes, it is necessary to temporarily stop the casting operation and prepare a new casting mold to make castings

However, when large and deep damage occurs on the surface of the mold, since it is necessary to remove a thick layer on the surface of the mold, there is also a problem that the life of the mold is drastically shortened due to the loss of the mold material.
