스텝사이즈의 제약이 없는 헤비블로우용기 성형용 금형{Metal mold for heavy blow molded containers}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a metal mold for heavy blow molded containers,

본 발명은 스텝사이즈의 제약이 없는 헤비블로우용기 성형용 금형에 관한 것으로, 더욱 상세하게는 열가소성수지를 이용하여 헤비블로우용기를 성형하는 립금형의 직경을 줄여 헤비블로우용기의 목부위의 접촉부분을 감소시킴으로써 금형의 직경을 작게 형성하여 캐비티 금형의 수를 늘릴 수 있어 생산성을 향상시키고 헤비블로우용기의 어깨부분에 다양한 직경의 테이퍼를 형성할 수 있어 다양한 용기를 성형할 수 있음은 물론 용기의 내구성을 향상시키고 스텝사이즈의 제약이 없는 헤비블로우용기 성형용 금형에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mold for molding a heavy blow-molded container free from the step size limitation, and more particularly, to a mold for molding a heavy blow-molded container using a thermoplastic resin, It is possible to increase the number of cavity molds by increasing the number of cavity molds, thereby improving the productivity and forming a taper of various diameters on the shoulder portion of the heavy-blowing container, thereby making it possible to form various containers, And to a mold for molding a heavy-blown container having no step size limitation.

일반적으로 헤비블로우용기를 성형하기 위해서는 열가소성 수지를 예열하는 예열스테이션과, 사출연신 블로우 성형장치에 의해 프리폼을 사출 성형하기 위한 프리폼 성형스테이션과, 상기 프리폼을 용기로 연신 블로우성형 하기 위한 블로우 성형스테이션과 상기 블로우 성형된 용기를 취출하는 취출 스테이션으로 구성된다.Generally, in order to form a heavy blow container, a pre-heating station for preheating the thermoplastic resin, a preform forming station for injection molding the preform by an injection stretch blow molding apparatus, a blow molding station for stretch blow molding with the preform, And a take-out station for taking out the blow-molded container.

이와 같은 상기 블로우성형 스테이션은 도 1에 도시된 바와 같이 프리폼의 입구를 형성하는 지지금형의 역할을 하는 분할금형의 립금형(1)을 형성하고 상기 립금형(1)에 의해 닫혀지는 위치에 캐비티금형(2)을 형성한다.As shown in FIG. 1, the blow molding station includes a lip mold 1 of a split metal mold serving as a support mold for forming an inlet of a preform, and at a position closed by the lip mold 1, Thereby forming a mold 2.

상기의 립금형(1)과 캐비티금형(2)은 립금형(1)에 의해 닫혀지는 캐비티금형(2)의 접촉면이 마모되거나 파손되는 것을 방지하고자 마모방지틈새(3)를 형성하고 상기 캐비티금형(2)은 용기의 직경과 동일한 직경의 용기입구를 형성하여 상기 용기입구를 닫은 상태로 프리폼(4)을 브로윙하여 용기를 형성한다.The lip mold 1 and the cavity mold 2 form a wear prevention gap 3 in order to prevent the contact surface of the cavity mold 2 closed by the lip mold 1 from being worn or damaged, (2) forms a container inlet having a diameter equal to the diameter of the container, and the preform (4) is blown with the container inlet closed to form a container.

이와 같은 종래의 블로우성형용 금형은 캐비티금형(2)의 용기입구보다 넓은 직경의 립금형(1)을 형성해야 하기 때문에 금형의 직경이 넓어져 캐비티 금형 숫자를 늘리는데 한계가 있어 생산성이 저하되는 문제점이 있었다.Such conventional blow molding dies are required to form the lip mold 1 having a larger diameter than the container mouth of the cavity mold 2, and thus the diameter of the mold is widened, which limits the number of cavity molds, .

또한, 용기의 어깨부분(neck)이 캐비티금형(2)의 단부의 마모방지틈새(3)에서 형성됨으로서 불로잉을 많이 하면 용기의 어깨부분이 도 2와 같이 형성되어 어깨부분(neck)과 몸체(body)의 연결부분이 불안정해지는 문제점이 있었으며 어깨부분(neck)의 모서리에 큰 라운딩을 형성하고나 경사면을 형성하여 성형할 수 없다는 문제점이 있었다.In addition, since the shoulder portion of the container is formed in the wear prevention gap 3 of the end portion of the cavity mold 2, if the bulging is excessive, the shoulder portion of the container is formed as shown in FIG. 2, there is a problem that the connecting portion of the body is unstable and a large rounding is formed at the corner of the shoulder portion and a slope is formed to form a problem.

이러한 문제점을 감안하기 위하여 과잉 블로잉을 방지하기 위하여 립금형(1)의 저면에 스텝홈(5)을 형성하여 용기를 생성하였을 경우 도 2 a와 같이 스텝부분(8)이 형성되어 용기에 뚜껑을 닫았을 경우 뚜껑에 의해 용기의 스텝부분에 하중이 집중되어 사용하거나 사용중 용기가 떨어질 경우 쉽게 파손되는 문제점이 있었으며 스텝부의 어깨부분(neck)이 수평이 되어야 한다는 문제점이 있었다.In order to prevent such a problem, in order to prevent excessive blowing, when a step groove 5 is formed on the bottom surface of the lip mold 1, a step portion 8 is formed as shown in FIG. 2A to form a lid There is a problem that the load is concentrated on the step portion of the container due to the lid when the container is closed or is easily broken when the container is dropped during use, and the shoulder portion of the step portion should be horizontal.

한편, 수평을 이루는 어깨부분(neck)으로 인하여 블로잉시 발생하는 가스를 배출하기 위하여 립금형(1) 저면에 가스가 배출되는 밴딩홈(6)를 형성하여 도 3에 도시된 바와 같이 어깨부분(neck)에 밴드돌기(7)가 남는 문제점이 있었다.3, a banding groove 6 is formed in the lower surface of the lip metal mold 1 to discharge gas generated during blowing due to the horizontal shoulder portion. As shown in FIG. 3, there is a problem that the band projection 7 remains on the neck.
