Description

멀티실린더형 중력 주조기{Munlti-cylinder type gravity die casting machine}Multi-cylinder type gravity die casting machine {Munlti-cylinder type gravity die casting machine}

본 발명은 멀티실린더형 중력 주조기에 관한 것으로, 더욱 상세하게는 상부금형과 하부금형으로 이루어진 금형조립체를 서로 대칭되도록 복수 개로 구비하여 밸런싱 특성을 향상시킨 멀티실린더형 중력 주조기에 관한 것이다.
The present invention relates to a multi-cylinder type gravity casting machine, and more particularly, to a multi-cylinder type gravity casting machine having a plurality of mold assemblies composed of an upper mold and a lower mold so as to be symmetrical with each other to improve balancing characteristics.

일반적으로 중력주조기는 용탕을 탕수에 저장한 다음 금형틀을 회전시켜 중력에 의해 용탕이 캐비티의 벽면을 타고 주입되도록 하여 용탕의 와류를 방지하는 방지하는 주조기이다.In general, the gravity casting machine is a casting machine which prevents the vortex of the molten metal by storing the molten metal in the hot water and then rotating the mold to allow the molten metal to be injected onto the wall of the cavity by gravity.

이러한 중력주조기는 주로 비중이 작거나 용융점이 낮은 알루미늄 합금에 주로 사용되며 자동차의 마스터 실린더 또는 디스크 브레이크에 사용되는 캘리퍼를 제조하는 데 사용된다.These gravity casting machines are mainly used for aluminum alloys with low specific gravity or low melting point, and are used to manufacture calipers used in automobile master cylinders or disc brakes.

이러한 중력주조기는 국내 등록특허 제370891호에 개시된 바와 같이 스탠드에 금형틀이 회동가능하도록 결합된다. 여기서 금형틀은 고정금형이 하부에 형성되고, 상부에는 고정금형과 접촉되도록 유압실린더에 의해 이동이 가능한 가동금형이 형성되어 있다. 또한 고정금형과 가동금형의 접촉면에는 각각 용탕이 충전되는 캐비티와 이 캐비티에 용탕을 안내하는 주입구가 형성되어 있다. 아울러 주입구의 일단에 용탕을 임시로 저장하기 위한 탕수가 설치되어 있다.Such gravity casting machine is coupled to the mold rotatable to the stand, as disclosed in the registered Korean Patent No. Here, the mold die is formed at the bottom of the mold, and the movable mold is formed at the top to be movable by the hydraulic cylinder to contact the fixed mold. In addition, a cavity filled with the molten metal and an injection hole for guiding the molten metal in the cavity are formed on the contact surfaces of the stationary mold and the movable mold. In addition, hot water is installed at one end of the inlet for temporarily storing the molten metal.

따라서 상기 중력주조기는 이동금형이 하부로 이동시켜 고정금형과 밀폐된 캐비티를 형성하도록 하고 금형틀을 회전시키면 탕수가 주입구와 캐비티보다 높은 위치에 배치되므로 용탕은 주입구를 통하여 캐비티의 벽면을 따라 점차적으로 주입된다. 상기와 같이 용탕이 캐비티의 벽면을 따라 점차적으로 주입됨에 따라 흘러가는 용탕이 와류를 형성하지 않으므로 기공이 발생하지 않아 제품의 품질이 향상된다.Therefore, the gravity casting machine moves the moving mold downward to form a closed cavity with the stationary mold, and when the mold is rotated, the hot water is placed at a position higher than the inlet and the cavity, so that the molten metal gradually moves along the wall of the cavity through the inlet. Is injected. As the molten metal is gradually injected along the wall surface of the cavity as described above, the flowing molten metal does not form a vortex and thus no pore occurs, thereby improving product quality.

상기 중력주조기는 생산성의 향상을 위하여 여러 벌의 금형이 동시에 승강하도록 구비되어 있다.The gravity casting machine is provided so that a plurality of molds are lifted at the same time in order to improve the productivity.

하지만 여러 벌의 금형을 동시에 승강시킬 경우 유압실린더에 걸리는 부하가 커서 큰 용량을 갖는 유압실린더를 구비해야 하는 문제점이 있다.However, when raising and lowering a plurality of molds at the same time, there is a problem in that a hydraulic cylinder having a large capacity is provided due to a large load on the hydraulic cylinder.

아울러 여러 벌의 금형을 동시에 승강시킬 경우 각 금형을 별도로 제어할 수 없으므로 단일한 종류의 제품만을 생산해야 하는 문제점이 있다.
In addition, when lifting a plurality of molds at the same time can not control each mold separately, there is a problem that only one type of product must be produced.

The bearing 12 is provided as a radial bearing so that the rotary shaft 60 protruding from both sides of the mold assembly 20 and 30 is fitted. Therefore, the mold assemblies 20 and 30 are rotated about the rotation shaft 60. In addition, the stand 10 is formed with a guide rod 14 that serves as a guide when the movable mold is elevated.

상기 금형조립체(20, 30)는 고정금형(22, 32)과 상기 고정금형(22, 32)의 상부에 승강이 가능하도록 설치된 가동금형(24, 34)과 상기 가동금형(24, 34)이 승강을 위하여 상기 가동금형(24, 34)에 개별적으로 설치된 유압실린더(26, 36)로 이루어진다.The mold assembly (20, 30) is a movable mold (24, 34) and the movable mold (24, 34) and the movable mold (24, 34) installed so as to be elevated on the fixed mold (22, 32) and the upper portion of the fixed mold (22, 32) It consists of hydraulic cylinders (26, 36) separately installed in the movable mold (24, 34) for this purpose.
