  • the present invention seeks to provide a variable casting mold that can extend the life and replacement cycle of the mold.
  • the present invention provides a pair of fixed sides spaced apart to face each other; And a pair of floating edges positioned between the fixed edges such that both longitudinal cross sections are movable in contact with the fixed edges, and the both longitudinal cross sections each having a recessed portion. And a molten metal is injected between the two sides and the floating sides.
  • the recess discloses a variable casting die, characterized in that extending to at least one of the edges of the longitudinal section of the floating side.
  • the main portion is made of a plurality of, it is disclosed a variable casting die, characterized in that formed on the longitudinal section of the floating side to be spaced apart from each other.
  • variable size casting die according to the present invention has the following effects.
  • variable casting mold according to the present invention includes a pair of fixed sides facing each other, and a pair of floating sides moving between the fixed sides with both longitudinal sections in contact with the fixed sides.
  • recesses are formed in both longitudinal cross-sections of the floating sides.
  • variable size casting die according to the present invention has the effect that it is possible to prevent the surface damage of the fixed sides due to the movement of the floating sides.
  • variable size casting die according to the present invention can prevent the surface damage of the fixed edges from being large and deeply expanded by the recesses, even if minute scratch damage occurs on the surface of the fixed edges due to the movement of the floating edges. . Due to this, the variable size casting die according to the present invention has the effect of providing a stable casting operation by preventing the occurrence of uneven solidified layer formation due to the surface of the damaged fixed edges to prevent accidents such as the solidified layer burst.
  • variable size casting die according to the present invention can prevent the expansion of damage and the problems caused by the fixed edges, has the effect of extending the life and replacement cycle of the mold.
  • FIG. 1 is a perspective view showing a variable casting die according to a first preferred embodiment of the present invention.
  • FIG. 2 is a side view illustrating the variable casting die shown in FIG. 1.
  • FIG. 3 is a perspective view illustrating various embodiments of recesses formed in the floating side of the variable casting mold shown in FIG. 1.
  • FIG. 1 is a perspective view showing the variable casting die 10 according to the first preferred embodiment of the present invention
  • FIG. 2 is a side view showing the variable casting die 10 shown in FIG.
  • the variable casting die 10 according to the first preferred embodiment of the present invention includes a fixed side 100 and a floating side 200, between the melting Metal is injected and the floating sides 200 may be moved to fabricate castings of various sizes.
  • the fixed sides 100 are spaced apart to face each other. At this time, the fixed sides 100 are maintained in a fixed state.
  • the floating sides 200 are positioned between the fixed sides 100, and both longitudinal cross-sections of the floating sides 200 are in contact with the fixed sides 100. At this time, both longitudinal cross-sections of the floating side 200 is pressed against the fixed side 100, the fixed side 100 and the floating side 200 is in close contact. Thus, when molten metal is injected between the fixed sides 100 and the floating sides 200, the molten metal is prevented from flowing out through the contact portion of the fixed sides 100 and the floating sides 200. do.
  • the floating sides 200 are movable between the fixed sides 100. As a result, the size of the casting formed in the variable casting die 10 can be changed. At this time, the floating sides 200 may move in opposite directions to each other, the size of the casting mold 10 may be changed. In addition, the other floating side 200 is moved in a state in which one floating side 200 is fixed, the size of the casting mold 10 may be changed.
  • recesses 211 are formed at both longitudinal cross-sections of the floating sides 200 in contact with the fixed sides 100.
  • the recessed part 211 has a shape recessed with respect to both longitudinal cross-sections of the floating sides 200, and reduces the area contacted between both longitudinal cross-sections of the floating sides 200 and the surfaces of the fixed sides 100. As a result, when the floating sides 200 move, the surface of the fixed side 100 may be prevented from being damaged due to friction with the floating side 102.
  • fine scratch damage may occur on the surface of the fixed edge 100 due to friction with the floating sides 200, but chips or debris separated from the surface of the fixed edge 100 due to the scratches It is inserted into the empty space formed by the 211 and the fixed side 100. For this reason, the surface damage of the fixed edge 100 can be prevented from expanding.
  • the recessed portion 211 of the floating side 200 can prevent the surface damage and the problems of the fixed side 100, thereby extending the life and replacement cycle of the mold 10.
  • FIG. 3 is a perspective view illustrating various embodiments of the recessed part 311 formed in the floating side 200 of the variable casting die 100 shown in FIG. 1.
