그리고 방전가공을 실시한다.(단계 50) 이때, 황삭 방전과 전해 방전을 실시한다.Then, discharge machining is performed. (Step 50) At this time, roughing discharge and electrolytic discharge are performed.

또한 와이어 컷 랜드 방전을 실시한다.(단계 60) 이때에도, 랜드 황삭 방전과 랜드 정삭 방전을 실시한다.Further, wire cut land discharge is performed. (Step 60) Also, land roughing discharge and land finishing discharge are performed.

이어서, 부분 방전을 실시한 후, 사상과 조립을 함으로써 금형이 완성된다.(단계 70,80)Subsequently, after the partial discharge, the mold is completed by finishing and assembling. (Steps 70 and 80)

상기와 같이 이루어지는 종래의 다이캐스팅 코어 금형 제조방법에 의해, 도 2에 도시된 바와 같이 랜드부를 제외한 일체형 코어 본체 전극이 제조되고, 도 3에 도시된 바와 같이 와이어 컷 가공에 의한 랜드부 부분 전극이 각각 제조된다.According to the conventional die casting core mold manufacturing method as described above, an integral core body electrode except for the land portion is manufactured as shown in FIG. 2, and the land portion electrodes by wire cut processing are respectively shown in FIG. 3.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 4에는 본 발명에 따른 다이캐스팅 금형용 일체형 전극 제조방법을 순차적으로 나타내 보인 개략적인 플로차트가 도시되어 있다. 여기에서는 일반적인 다이캐스팅 금형용 일체형 전극 제조방법의 설명은 생략하고, 본 발명의 특징에 따른 방법을 설명하기로 한다.4 is a schematic flowchart sequentially illustrating a method of manufacturing an integrated electrode for a die casting mold according to the present invention. Herein, a description of a general method of manufacturing an integrated electrode for a die casting mold will be omitted, and a method according to the features of the present invention will be described.

도면을 참조하면, 본 발명에 따른 다이캐스팅 금형용 일체형 전극 제조방법은, 랜드부와 코어 본체를 일체형으로 가공하기 위한 것으로, 우선, 다이캐스팅 금형을 면삭 가공한다.(단계 110)Referring to the drawings, the integrated electrode manufacturing method for a die casting mold according to the present invention is for integrally processing the land portion and the core body, and first of all, the die casting mold is face-machined.

이어서, 상기 금형을 황삭 및 중삭으로 1차 가공한다.(단계 120)Subsequently, the die is first processed by roughing and medium cutting (step 120).

그리고 이 금형을 열처리하고, 정삭으로 2차 가공한다.(단계 130,140)The mold is then heat-treated and subjected to secondary processing by finishing (steps 130, 140).

또한 상기 금형을 일체형 방전을 실시하고, 부분 방전을 실시한다.(단계 150,160)In addition, the mold is discharged integrally and partial discharge is performed (steps 150 and 160).

이어서, 상기 금형을 사상하고, 조립한다.(단계 170)The mold is then mapped and assembled (step 170).

한편, 상기 단계 150에서, 상기 일체형 방전은 황삭 방전과 전해 방전으로 이루어진다.On the other hand, in the step 150, the unitary discharge consists of roughing discharge and electrolytic discharge.

상술한 바와 같은 본 발명에 따른 다이캐스팅 금형용 일체형 전극 제조방법에 따라 도 5에 도시된 바와 같은 랜드부와 코어 본체를 일체형으로 한 일체형 전극이 제조된다.According to the method of manufacturing an integrated electrode for a die casting mold according to the present invention as described above, an integrated electrode in which the land portion and the core body as shown in FIG. 5 are integrated is manufactured.

따라서 본 발명은, 다이캐스딩 코어 금형 제작시 랜드부 와이어 컷에 의한 공정과 라운드 성형을 위한 방전가공 등의 2중 전극 제작을 하지 않아도 된다. 그러면 형상부와 랜드부를 일체형으로 가공할 수 있게 된다.Accordingly, the present invention does not require the production of a double electrode such as a process by land-wire cutting and a die-cutting process for round molding during die casting core die fabrication. Then, the shaped portion and the land portion can be processed integrally.

이와 같이 일체형 전극 제작으로 인해 랜드 와이어 컷 전극 가공 공정이 삭제된다. 이에 따라 와이어 컷 랜드 방전이 필요 없게 된다. 또한 라운드부 성형 사상이 필요 없다.As such, the land wire cut electrode processing process is eliminated due to the integrated electrode fabrication. This eliminates the need for wire cut land discharge. In addition, there is no need for round molding.

상술한 바와 같이 본 발명에 따른 다이캐스팅 금형용 일체형 전극 제조방법은 다음과 같은 효과를 갖는다.As described above, the integrated electrode manufacturing method for a die casting mold according to the present invention has the following effects.

와이어 컷 전극 가공과 와이어 컷 방전의 두 공정이 삭제된다. 따라서 공정이 단순화됨은 물론, 작업의 능률이 향상으로 인한 금형제작 기간이 단축된다.Two processes of wire cut electrode processing and wire cut discharge are eliminated. This simplifies the process and shortens the mold manufacturing period due to improved work efficiency.

그리고 가공시간 단축으로 원가가 절감될 수 있고, 전극 재료비가 절감되어 결국 원가가 절감이 이루어질 수 있게 된다.In addition, the cost can be reduced by reducing the processing time, and the cost of the electrode material can be reduced, thereby reducing the cost.

본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호 범위는 첨부된 특허청구범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
