이하 본 발명의 바람직한 실시예에 따른 주조용 다목적 사형틀을 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, with reference to the accompanying drawings, the multi-purpose casting mold for casting according to a preferred embodiment of the present invention will be described in detail. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

본 발명에 따른 주조용 다목적 사형틀(100)은 도 2 및 도 3에 도시된 바와 같이, 베이스(10)와, 베이스(10)의 측면에 결합되는 이동부재(15)에 의하여 결합되는 실린더부재(20) 및 실린더부재(20)의 로드(21)에 결합되는 격판(30)을 구비한다.Casting multi-purpose sanding die 100 according to the present invention, as shown in Figures 2 and 3, the cylinder member coupled by the base 10, the moving member 15 is coupled to the side of the base 10 And a diaphragm 30 coupled to the rod 21 of the cylinder member 20.

상기 베이스(10)는 대략 직육면체의 형상을 이룬다. 상기 베이스(10)의 4개의 측면의 각각에는 가이드홈(11)이 마련된다. 상기 가이드홈(11)에는 가이드홈(11)에 형입되는 돌기(13)가 형성된 이동부재(15)가 가이드홈(11)을 따라 슬라이드 가능하도록 설치된다. 상기 이동부재(15)에는 실린더부재(20)의 로드(21)가 베이스(10)의 내측을 향하도록 결합된다.The base 10 has a substantially rectangular parallelepiped shape. Guide grooves 11 are provided at each of the four side surfaces of the base 10. The guide groove 11 is provided with a movable member 15 having a projection 13 formed in the guide groove 11 so as to slide along the guide groove 11. The rod 21 of the cylinder member 20 is coupled to the movable member 15 to face the inside of the base 10.

따라서, 상기 실린더부재(20)는 이동부재(15)에 의하여 베이스(10)의 측면을 따라서 이동가능 하도록 겹합되는 것이다. 상기 실린더부재(20)의 로드(21)에는 격판(30)이 설치된다.Therefore, the cylinder member 20 is overlapped to be movable along the side of the base 10 by the moving member 15. A diaphragm 30 is installed on the rod 21 of the cylinder member 20.

상기 격판(30)은 실린더부재(20)의 로드(21)에 결합되는 연결플레이트(31)에 볼트결합된다. 상기 격판(30)은 베이스(10)의 대향되는 측면에 각각 설치된 실린더부재(20)의 로드(21)에 의하여 베이스(10)의 상면에서 위치 변화된다. 따라서, 상기 격판(30)은 실린더부재(20)의 위치와 로드(21)의 신장량에 의하여 서로 접촉되어 면적이 달라지는 공간부(33)를 형성한다. 상기 공간부(33)는 주물사에 의하여 주형을 만드는 공간을 말한다. 상기 공간부(33)에 주입되는 주물사는 실린더부재(20)에 의하여 압력이 가하여지고, 주물사에 삽입되는 주형 또한 압력을 받으면서 굳어져 표면조도의 향상을 이룰 수 있게 된다.The diaphragm 30 is bolted to the connection plate 31 coupled to the rod 21 of the cylinder member 20. The diaphragm 30 is changed in position on the upper surface of the base 10 by rods 21 of the cylinder members 20 respectively provided on opposite sides of the base 10. Thus, the diaphragm 30 forms a space portion 33 in contact with each other due to the position of the cylinder member 20 and the amount of extension of the rod 21 to vary in area. The space portion 33 refers to a space for making a mold by molding sand. The molding sand injected into the space 33 is pressurized by the cylinder member 20, and the mold inserted into the casting sand is also hardened under pressure, thereby improving surface roughness.

상기의 구성을 갖는 본 발명에 따른 주조용 다목적 사형틀의 작용을 설명한다.It demonstrates the operation of the multi-purpose sanding die for casting according to the present invention having the above configuration.

본 발명의 주조용 다목적 사형틀(100)의 주물사가 주입되는 공간부(33)의 크기를 주형의 종류에 맞도록 결정한다.The size of the space portion 33 into which the molding sand of the multipurpose sanding die 100 for casting of the present invention is injected is determined to match the type of the mold.

그리고, 상기 결정된 공간부(33)를 격판(30)의 조합에 의하여 형성 할 수 있도록 베이스(10)의 측면에 결합된 실린더부재(20)의 위치를 조정하고, 로드(21)의 길이를 변화시켜 격판(30)이 상호 접촉되도록 하여 공간부(33)를 이루도록 한다.Then, to adjust the position of the cylinder member 20 coupled to the side of the base 10 so as to form the determined space portion 33 by the combination of the diaphragm 30, change the length of the rod 21 The plates 30 are in contact with each other to form the space part 33.

다음, 상기 공간부(33)에 주물사를 주입한 후 주물사가 굳어지면, 실린더부재(20)의 로드(21)를 최초위치로 변화시켜 주물사로부터 주형을 분해하여 원하는주조물을 만든다.Next, when the casting sand is hardened after injecting the molding sand into the space 33, the rod 21 of the cylinder member 20 is changed to the initial position to disassemble the mold from the casting sand to make a desired casting.

이상, 본 발명을 도면에 도시된 실시예를 참조하여 설명하였다. 그러나, 본 발명은 이에 한정되지 않고 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명과 균등한 범위에 속하는 다양한 변형예 또는 다른 실시예가 가능하다. 따라서, 본 발명의 진정한 보호범위는 이어지는 특허청구범위에 의해 정해져야 할 것이다.The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art. Therefore, the true scope of protection of the present invention should be defined by the following claims.

상기와 같은 본 발명에 따른 주조용 다목적 사형틀은 다음과 같은 효과를 갖는다.Multipurpose sanding die for casting according to the present invention as described above has the following effects.

실린더부재에 의하여 작동되는 격판을 이용하여 사형틀을 제작함으로써, 다양한 주형의 크기에 대응할 수 있는 사형틀을 제작할 수 있다.By manufacturing the sand mold using the diaphragm operated by the cylinder member, it is possible to produce a sand mold that can correspond to the size of the various molds.

그리고, 실린더부재의 압력을 이용하여 주형을 제작 할 수 있음으로써, 표면조도가 우수한 주형을 제작할 수 있다.And, by using the pressure of the cylinder member can be produced by the mold, it is possible to produce a mold with excellent surface roughness.
