상기 캐비티(300)의 하측에 유압실린더(60)의 피스톤(61)에 의해 승하강 작동하는 스퀴즈 코어(65)를 설치하여 상기 캐비티에서 성형되는 차량용 압축기 부품의 일정 부위를 가압하여 단조 성형하도록 이루어진다.The squeeze core 65 which is moved up and down by the piston 61 of the hydraulic cylinder 60 is installed at the lower side of the cavity 300 so as to press a predetermined portion of the vehicle compressor component formed in the cavity and forge-form it. .

이때 상기 캐비티(300)에서 성형되는 차량용 압축기 부품은 도 3a,b,c에서와 같은 피스톤(2a), 소켓플레이트(2b), 스와시(2c) 등에 적용된다.At this time, the vehicle compressor component formed in the cavity 300 is applied to a piston 2a, a socket plate 2b, a swash 2c, and the like as shown in FIGS. 3A, 3B and 3C.

미설명부호로서, 70은 성형품(2)을 추출하는 이젝트 핀을 나타내는 것이다.Reference numeral 70 denotes an eject pin for extracting the molded article 2.

다음은 상기와 같이 구성되는 본 발명의 작동 및 작용에 대해 살펴보기로 한다.Next will be described the operation and action of the present invention configured as described above.

먼저 본 발명의 다이캐스팅 성형장치는 차량의 압축기 부품인 도 4a,b,c의 피스톤(2a), 소켓플레이트(2b), 스와시(2c) 등을 성형하여 제조하기에 적합한 것이다.First, the die casting molding apparatus of the present invention is suitable for molding and manufacturing the piston 2a, the socket plate 2b, the swash 2c, and the like, which are compressor components of the vehicle.

이러한 장치의 작동관계를 좀더 구체적으로 설명하면, 먼저 알루미늄을 용융한 용탕을 슬리브(10)에 공급하여 급탕하면서 사출피스톤(30)의 가압작동으로 런너(20)를 통해 금형의 캐비티(300)로 공급 충진하게 된다.In more detail, the operation relationship of such a device is first supplied to the sleeve 300 by supplying the molten aluminum molten metal to the sleeve 10 to supply the hot water to the cavity 300 of the mold through the runner 20 through the pressurization operation of the injection piston 30. Supply is filled.

이때 상기 사출피스톤(30)의 가압에 의한 용탕의 공급은 저속- 고속후 고속으로 진행함이 바람직하다.At this time, the supply of the molten metal by the pressurization of the injection piston 30 is preferably low-speed and then proceeds to high speed.

이와 같이 상기 사출피스톤(30)의 가압으로 용탕을 캐비티(300)에 공급함과 함께 상기 캐비티(300) 내부의 공기는 진공수단(50), 즉 진공블럭(51), 진공탱크(52) 및 진공펌프(53)에 의해 캐비티 내부의 공기를 외부로 흡입 배출하여 캐비티(300) 내부를 진공으로 유지하게 된다.As such, the molten metal is supplied to the cavity 300 by the pressurization of the injection piston 30, and the air in the cavity 300 is vacuum means 50, that is, the vacuum block 51, the vacuum tank 52, and the vacuum. The pump 53 sucks and discharges the air inside the cavity to the outside to maintain the inside of the cavity 300 in a vacuum.

따라서, 상기 사출피스톤(30)의 가압으로 캐비티에 공급되는 용탕은 진공을 이루는 캐비티(300)에 전체적으로 충진됨이 효과적으로 제공되게 된다.Therefore, the molten metal supplied to the cavity by the pressurization of the injection piston 30 is effectively provided to be filled in the cavity 300 forming a vacuum.

이와 같이하여 상기 용탕이 진공수단(50)의 진공블럭(51)에 도달하도록 충진되면 캐비티(300)의 충진이 완료되어 용탕의 충진이 중단됨과 함께 진공수단(50)의 진공 흡입 작동도 멈추게 된다.In this way, when the molten metal is filled to reach the vacuum block 51 of the vacuum means 50, the filling of the cavity 300 is completed to stop the filling of the molten metal and the vacuum suction operation of the vacuum means 50 is also stopped. .

이와 같이 금형의 캐비티(300) 내부로 용탕이 공급되면, 이를 냉각하여 성형품을 성형하게 되는데, 이때 상기 성형품(2)이 응고되기 전에 성형품의 단조 물성치가 필요한 위치로 설치된 스퀴즈 코어(65)를 하부의 유압실린더(60)에 의해 승하강 작동시킨다.When the molten metal is supplied into the cavity 300 of the mold as described above, the molten metal is cooled to form a molded product. At this time, before the molded product 2 is solidified, the squeeze core 65 installed at a position where the forged physical property of the molded product is required is lowered. Lifting and lowering operation by the hydraulic cylinder 60 of.

즉, 상기 스퀴즈 코어(65)가 성형품(2)의 일정 부위를 가압하여 단조 성형하게 되는 것이다.That is, the squeeze core 65 is forged by pressing a predetermined portion of the molded article (2).

이와 같이하여 금형 캐비티(300)에서 성형된 성형품(2)이 냉각되면, 상기 금형의 형개방과 함께 성형품을 이젝팅하여 추출하게 되는 것이다.In this way, when the molded article 2 formed in the mold cavity 300 is cooled, the molded article is ejected together with the mold opening of the mold.

이와 같은 1사이클의 공정에 의해 성형품이 성형 완료되면 계속적으로 전술한 바와 같이 캐비티에 용탕의 공급과 함께 진공작동, 단조 성형 작동을 거쳐 성형품을 반복 생산하게 되는 것이다.When the molded article is molded by the one-cycle process as described above, the molded article is repeatedly produced through the vacuum operation and the forging molding operation together with the supply of the molten metal to the cavity as described above.

특히, 본 발명에서는 종래 단조 방식에 의해 생산되던, 차량용 압축기 부품인 피스톤, 소켓플레이트, 스와시 등의 부품을 다이캐스팅 성형장치에 의해 성형하되, 진공방식 및 단조방식을 함께 적용하므로 성형품의 성형 정밀도 및 물성을 우수하게 제공함은 물론 생산성 향상, 제조원가 절감을 우수하게 제공하게 되는 것이다.Particularly, in the present invention, the parts such as piston, socket plate, swash and the like, which are conventionally produced by the forging method, are molded by a die casting apparatus, but the vacuum method and the forging method are applied together, so that the molding precision and Providing excellent physical properties as well as improving productivity and reducing manufacturing costs.
