The present invention relates to a die casting plunger configured to be utilized.

일반적으로 플런저는 도 1에 도시한 바와 같이 슬리브 실린더(1)로 주입되는 성형소재를 일정량씩 배출시키도록 상기 슬리브 실린더(1)의 내부에 왕복 이송 가능하게 배치된 피스톤로드(2)의 선단부에 결합되는 것으로, 대부분 주물이나 SKD-61종 또는 수입에 의존되는 소량의 베릴륨동 등과 같은 소재로 성형된다.In general, the plunger is disposed at the distal end of the piston rod 2 disposed in the sleeve cylinder 1 in a reciprocating manner so as to discharge the molding material injected into the sleeve cylinder 1 by a predetermined amount, as shown in FIG. 1. Combined, most are molded from materials such as castings, SKD-61 species or small amounts of beryllium copper, depending on imports.

이러한 플런저(10)의 구성은 도 2 및 도 3에 도시한 바와 같이 피스톤로드(2)와 결합되는 장착부(11)와, 성형소재를 밀어내는 주입부(12)로 이루어지며, 상기 주입부(12)의 선단부에는 용탕 주입시 압력을 용이하게 수용할 수 있도록 하는 단턱부(13)가 둘레를 따라 형성되고, 상기 주입부(12)의 내부에는 용탕 주입시 수축상태를 용이하게 수용할 수 있도록 하는 공간부(14)가 형성되며, 상기 공간부(14)에 연이어 피스톤로드(2)가 결합되는 나사공(15)이 형성되고, 상기 장착부(11)는 외측으로 장착이 용이하게 사각 또는 육각 및 팔각형상으로 형성되며, 상기 장착부(11)의 내부에는 피스톤로드(2)가 삽입되는 삽입홀(16)이 형성되어 구성된다.2 and 3, the plunger 10 includes a mounting portion 11 coupled to the piston rod 2, and an injection portion 12 for pushing a molding material. A stepped portion 13 is formed along the circumference of the distal end portion 12 so as to easily receive the pressure during the injection of the melt, and the inside of the injection portion 12 to easily accommodate the contracted state during the injection of the melt. The space portion 14 is formed, and the screw hole 15 to which the piston rod 2 is coupled to the space portion 14 is formed, and the mounting portion 11 is easily squared or hexagonal to the outside And an octagonal shape, and an insertion hole 16 into which the piston rod 2 is inserted is formed in the mounting portion 11.

그러나, 이와 같은 이러한 종래의 플런저(10)는 SKD-61으로 성형되는 경우 플런저(10)의 강도가 너무 높기 때문에 플런저(10)가 슬라이드 되면서 슬리브 실린더(1)에 무리를 주게되어 슬리브 실린더(1) 내주면에 스크러치(긁힘)을 내는 문제점이 있었다.However, such a conventional plunger 10 has a high strength of the plunger 10 when it is molded with SKD-61, so that the plunger 10 slides and gives a strain to the sleeve cylinder 1 so that the sleeve cylinder 1 ) There was a problem of scratching (scratch) on the inner circumferential surface.

또한, 주물로 성형되는 경우에는 강도가 너무 약하기 때문에 마모가 심하거나 부분적으로 크랙이 발생 됨으로 다이캐스팅 작업을 중단한 후 플런저(10)를 자주 교체해야 하는 문제점이 있었다.In addition, when molded into a casting, because the strength is too weak, there is a problem that the plunger 10 must be frequently replaced after stopping the die casting operation due to severe wear or partial cracking.

또한, 베릴륨동으로 성형되는 경우에는 상기와 같은 즉 SKD-61이나 주물로 성형되었을 경우에 발생되었던 문제점을 어느 정도 해소할 수는 있으나 이 역시 재료비가 비싸기 때문에 쉽게 선택되어 이용될 수 없었던 문제점이 있었다.In addition, in the case of molding with beryllium copper, it is possible to solve some of the problems caused by the molding of SKD-61 or casting as described above, but this also has a problem in that it cannot be easily selected and used because of high material costs. .

또한, 종래의 플런저(10)는 마모되거나 부분적으로 파손된 경우 플런저(10) 전체를 폐기하게됨으로 소중한 자원이 무분별하게 낭비되는 문제점이 있었다.In addition, the conventional plunger 10 has a problem in that valuable resources are indiscriminately waste because the entire plunger 10 is disposed when worn or partially broken.
