Description

금형 코어 분리장치{A Disassemble Apparatus for Die Casting-Core}Mold Disassembly Apparatus {A Disassemble Apparatus for Die Casting-Core}

본 발명은 금형 코어 분리장치에 관한 것으로, 더욱 상세하게는 유압실린더를 이용하여 간단히 코어와 홀더를 분리시키도록 하여 작업성을 향상시킨 금형 코어 분리장치에 관한 것이다.The present invention relates to a mold core separating apparatus, and more particularly, to a mold core separating apparatus which improves workability by simply separating the core and the holder by using a hydraulic cylinder.

주지된 바와 같이 다이캐스팅을 통해 생산되는 장치의 분야는 상당히 넓다.As is well known, the field of devices produced through die casting is quite wide.

차량의 경우에도 트랜스미션 케이스는 다이캐스팅을 통해 제작되며, 다이캐스팅은 금형에 고압을 이용하여 용해된 금속을 주입하는 방법으로 주물의 정밀도가 높고 표면이 매끄러워 기계 다듬질 등의 후처리가 편리하기 때문이다.In the case of a vehicle, the transmission case is manufactured through die casting, and die casting is a method of injecting molten metal using high pressure into a mold, so the casting precision is high and the surface is smooth, which is convenient for post-processing such as machine finishing.

다이캐스팅 장치는 다수의 슬라이드와 홀더로 구분되어지며, 다이캐스팅 작업 완료후에는 슬라이드와 홀더 및 코어를 분리하여야 한다.The die casting device is divided into a plurality of slides and holders, and the slides, holders and cores should be separated after the die casting operation is completed.

예시도면 도 1 은 종래 코어 분리방법을 나타낸 개념도로서, 종래에는 슬라이드 홀더(1)에 코어(2)가 부착되어 있는 상태에서 코어분해용 홀(3)에 분리봉(미도시)을 삽입한 후 해머(미도시)로 분리봉을 가격하여 코어(2)와 홀더(1)를 분리하는 방법을 취하고 있었다.Exemplary drawing Figure 1 is a conceptual diagram showing a conventional core separation method, conventionally after inserting a separation rod (not shown) in the core disassembly hole 3 in the state that the core 2 is attached to the slide holder (1) A method of separating the core 2 and the holder 1 by hammering a separation rod with a hammer (not shown) was taken.

그러나, 이러한 해머의 사용에 의한 안전사고 발생의 우려가 있으며, 수작업에 따른 불편함이 발생되었다.However, there is a risk of safety accidents caused by the use of such a hammer, inconvenience caused by manual work.

또한, 금형 분해시간이 과도하며, 노후 금형의 조립면에 발생된 녹에 의해 분해가 까다로왔던 것이다.In addition, the mold disassembly time is excessive, and decomposition is difficult due to rust generated on the assembled surface of the old mold.

이에 본 발명은 상기 문제점을 개선하기 위하여 안출된 것으로, 유압실린더를 이용하여 코어와 홀더를 분리시키는 금형 코어 분리장치를 제공함에 그 목적이 있는 것이다.The present invention has been made to improve the above problems, and an object thereof is to provide a mold core separating device for separating the core and the holder by using a hydraulic cylinder.

이를 위한 본 발명은 유압실린더의 작동력으로 코어와 홀더를 분리작업을 수행토록 한 것으로, 지지몸체에 실린더를 설치하여 실린더로드에 홀더로의 걸이수단을 장착하는 한편, 지지몸체의 측부에는 코어를 지지고정하는 코어지지수단을 장착하여, 코어가 지지고정된 상태에서 유압력으로 홀더를 분리하도록 한 것이다.To this end, the present invention is to separate the core and the holder by the operating force of the hydraulic cylinder, the cylinder is installed on the support body to mount the hook means to the holder on the cylinder rod, while holding the core on the side of the support body The core support means is set so that the holder can be separated by hydraulic force while the core is fixed.

예시도면 도 2 는 본 발명에 따른 금형코어 분리장치를 나타낸 외관설명도이고, 예시도면 도 3 은 본 발명에 따른 금형코어 분리장치의 작동상태를 나타낸 평단면설명도이다.Exemplary drawings Figure 2 is an external view showing the mold core separating apparatus according to the present invention, Figure 3 is a cross-sectional plan view showing an operating state of the mold core separating apparatus according to the present invention.

본 발명은 먼저 지지몸체(10)가 마련되어 이 지지몸체(10)에 실린더(12)가 설치된다.In the present invention, the support body 10 is first provided, and the cylinder 12 is installed on the support body 10.

여기서, 상기 실린더(12)에 스위치등의 실린더 작동의 제어수단이 포함됨은당연하며, 유압실린더가 사용됨이 일반적이다.Here, it is obvious that the cylinder 12 includes a control means for operating a cylinder such as a switch, and a hydraulic cylinder is generally used.

그리고, 지지몸체(10)에는 본 발명인 분리장치의 이동이 가능하게 캐스터(14)가 설치된다.And, the support body 10 is provided with a caster 14 to enable the movement of the separation device of the present invention.

한편, 상기 실린더(12)의 실린더 로드(16)에는 홀더(1)에 실린더(12)의 작동력이 전달되게 걸이수단(18)이 설치된다.On the other hand, the cylinder rod 16 of the cylinder 12 is provided with a hook means 18 so that the operating force of the cylinder 12 is transmitted to the holder (1).

걸이수단(18)은 실린더 로드(16) 선단에 장착된 후크지지대(20)와 이 후크지지대(20)의 양단에 설치되어 홀더(1)의 측단에 거치되는 후크(22)로 이루어진다.The hook means 18 is composed of a hook support 20 mounted on the end of the cylinder rod 16 and a hook 22 mounted on both ends of the hook support 20 and mounted on the side end of the holder 1.

이와 더불어, 상기 지지몸체(10)에는 상기 실린더(12)의 압축에 의해 홀더(1)가 코어(2)에서 분리되게 코어(2)를 지지고정시키는 코어지지수단(26)이 설치된 것이다.In addition, the support body 10 is provided with a core support means 26 for supporting and fixing the core 2 so that the holder 1 is separated from the core 2 by the compression of the cylinder 12.

여기서, 코어지지수단(26)은 지지몸체(10) 양측에 설치된 코어지지대(26)와 코어(2)에 삽입되어 코어지지대(26)를 통해 실린더(12)의 작동력에 대항하는 지지봉(28)으로 이루어진다.Here, the core support means 26 is inserted into the core support 26 and the core 2 installed on both sides of the support body 10 and the support rod 28 against the operating force of the cylinder 12 through the core support 26. Is done.

따라서, 작업자는 지지봉(28)을 코어(2)에 삽입한 다음 코어지지대(26)를 지지봉(28)에 거치시킨다.Thus, the operator inserts the support rod 28 into the core 2 and then mounts the core support 26 to the support rod 28.

상기 코어지지대(26)는 지지몸체(10)에 결합되어 있지만, 지지몸체(10)에는 캐스터(14)가 장착되어 있으므로, 지지몸체(10)를 이동시켜 코어지지대(26)를 지지봉(28)에 거치시키는 것이 용이하다.The core support 26 is coupled to the support body 10, but since the caster 14 is mounted on the support body 10, the support body 10 is moved to support the core support 26 to the support rod 28. It is easy to mount on.

다음으로, 실린더(12)를 조작하여 홀더(1)에 걸이수단(18)를 근접시킨 다음 벌어져 있는 후크(22)를 오므려 홀더(1)의 양측단에 후크(22)를 거치시키고, 실린더(12)를 작동시키면 유압 실린더의 실린더 로드(16)가 압축되면서 그 작동력이 후크(22)를 통해 홀더(1)에 전달된다.Next, the hook 12 is brought close to the holder 1 by operating the cylinder 12, and then the hook 22 is opened to mount the hooks 22 at both ends of the holder 1, and the cylinder When the 12 is operated, the cylinder rod 16 of the hydraulic cylinder is compressed and its operating force is transmitted to the holder 1 through the hook 22.

이때, 코어(2)는 코어지지대(26)와 지지봉(28)에 의해 실린더(12)의 작동력에 저항하므로, 실린더(12)의 힘에 의해 코어(2)와 홀더(1)가 간단한 작업으로 분리되는 것이다.At this time, since the core 2 resists the operating force of the cylinder 12 by the core support 26 and the support rod 28, the core 2 and the holder 1 are operated by the force of the cylinder 12 in a simple operation. It is to be separated.

상술된 바와 같이 본 발명에 따르면, 실린더의 유압에 의해 코어와 홀더가 분리되고 이러한 실린더는 간단한 스위치조작으로 작동되어짐으로써, 코어와 홀더의 분리작업이 간편해져 금형부품의 생산성이 향상되는 이점이 있다.As described above, according to the present invention, the core and the holder are separated by the hydraulic pressure of the cylinder, and the cylinder is operated by a simple switch operation, so that the separation work of the core and the holder is simplified, thereby improving the productivity of the mold parts. .
