Description

범퍼 펀칭장치 {Punching apparatus of bumper}Bumper punching device {Punching apparatus of bumper}

본 발명은 범퍼 펀칭장치에 관한 것으로서, 더욱 상세하게는 생산성이 향상되도록 개량된 범퍼 펀칭장치에 관한 것이다.The present invention relates to a bumper punching device, and more particularly, to a bumper punching device improved to improve productivity.

일반적으로 차량의 범퍼는 가열 실린더 내에서 가열 용해된 용융수지를 고압으로 사출금형기의 캐비티(cavity) 영역 내에 주입, 및 일정시간 경과되어 고화시킨 후, 사출됨으로서 형성된다.In general, a bumper of a vehicle is formed by injecting molten resin heated and dissolved in a heating cylinder at a high pressure into a cavity region of an injection molding machine, and solidifying after a predetermined time.

상술한 사출금형기는 고정금형과 가동금형으로 구성되는바, 상기 가동금형은 형체 장치에 의해 고정금형으로부터 왕복 이송됨으로써 형개(型開), 형폐(型閉) 및 형체(型締)를 수행한다.The above-mentioned injection mold is composed of a stationary mold and a movable mold, and the movable mold is reciprocally transferred from the stationary mold by a mold clamping device to perform mold opening, mold closing, and mold clamping.

한편, 통상의 범퍼에는 홀이 필요치 않으나, 최근에는 사용자의 요구에 따른 차량 편의장치로서 차량 전, 후방 범퍼의 다수개소에 전, 후방 감지장치를 부착하기 위해 펀칭홀을 형성시키게 되었다.On the other hand, a hole is not required for a conventional bumper, but recently, as a vehicle convenience device according to a user's request, a punching hole has been formed to attach the front and rear sensing devices to a plurality of places of the front and rear bumpers.

이를 위해 종래에는 상술한 사출금형기와 별도의 펀칭장치가 구비되어 이 펀칭장치로 이송시키기 위한 추가 인력이 소요되는 문제가 있으며, 이에 따라 제품의 생산성 또한 저하되는 문제가 발생된다.To this end, there is a problem in that a conventional punching device and a separate punching device are provided, which requires an additional manpower for transferring to the punching device, thereby lowering the productivity of the product.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 사출과 펀칭을 병행할 수 있는 범퍼 펀칭장치를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, and an object thereof is to provide a bumper punching device capable of performing injection and punching in parallel.
