Description

다수개의 노즐이 연결된 핫런너 시스템{Hot runner system connected multiple nozzles}Hot runner system connected multiple nozzles

본 발명은 플라스틱 제품 사출 성형용 핫런너 시스템으로서, 특히 노즐이 다수개 장착된 핫런너 시스템에 관한 것이다.The present invention relates to a hot runner system for injection molding of plastic products, and more particularly to a hot runner system equipped with a plurality of nozzles.

일반적으로 하나의 핫런너 시스템에는 한개나 두개의 노즐을 고정 장착하는 것이 상례이고 그 이상의 노즐은 장착할 수가 없었다.In general, one hot runner system is usually fixed to one or two nozzles and no more nozzles can be mounted.

따라서 동일 제품을 동시에 다량으로 양산할 수 없는 불편이 있었고 일시에 다량의 제품을 생산할 필요가 있을 경우 다수개의 핫런너 시스템을 이용해야하므로 넓은 장소가 필요하게되고 일일이 핫런너 시설을 장치해야하는 불편이 있었고 이로인해 인건비 및 시설비의 증가로 원가상승의 요인이 되었다.Therefore, it was inconvenient to mass-produce a large amount of the same product at the same time, and when it was necessary to produce a large amount of products at one time, a large space was needed because a large number of hot runner systems were used, and there was a inconvenience of having to install a hot runner facility every day This led to an increase in labor costs and facility costs, which led to a cost increase.

본 발명은 상기한 바와같은 종래의 플라스틱 제품 사출 성형용 핫런너 시스템의 결점을 개선하여 하나의 핫런너 시스템에 다수개의 노즐을 병열로 장착하여 동일 제품을 동시에 대량으로 생산할 수 있는 다수개의 노즐이 장착된 핫런너 시스템을 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention is to improve the shortcomings of the conventional injection molding hot runner system for plastic products as described above by mounting a plurality of nozzles in parallel to one hot runner system is equipped with a plurality of nozzles that can produce the same product in large quantities simultaneously The present invention provides a hot runner system, which will be described in detail with reference to the accompanying drawings.

노즐이 장착된 플라스틱 제품 사출 성형용 핫런너 시스템에 있어서, 한개의 핫런너 시스템에 다수개의 노즐을 장착하기 위해서 하나의 노즐형태를 중앙의 탕도(1)를 중심으로 그 좌우에 봉히터(2)(2')를 장착한 것으로 하되, 그렇게 형성된 노즐을 좌우는 길고 전후가 짧은 장방형 형태로하여 그 노즐(6)(6')...다수개를 병열로 배열하고, 그 각 노즐(6)(6')...사이 마다에는 1mm내외의 단열층(5)을 형성하고 그 노즐(6)(6')...양측 내부에는 각 노즐(6)(6')...을 연결고정하는 세로방향 고정판(3)(3')을 삽착한 다음, 상기 고정판(3)(3')의 측면을 방향키(4)(4')로 각각 고정한 것으로 구성된 것이다.In the hot runner system for injection molding plastic products equipped with nozzles, in order to mount a plurality of nozzles in one hot runner system, one nozzle type is formed on the left and right sides of the center heater (1). 2 '), and the nozzles thus formed are formed in a rectangular shape having a long and short length of right and left, and the nozzles 6, 6' ... are arranged in parallel, and each nozzle 6 Between each (6 ') ..., a thermal insulation layer (5) of about 1 mm is formed and each nozzle (6) (6') ... is connected to both nozzles (6) (6 ') ... After inserting the longitudinal fixing plate (3) (3 ') for fixing, and then fixed to the side of the fixing plate (3) (3') with direction keys (4) (4 '), respectively.

이와같이 구성되는 다수개의 노즐(6)(6')...이 연결된 핫런너 시스템은 각 노즐(6)(6')...의 히터(2)(2')가 코일형 히터가 아닌 작은 봉히터로 되어 탕도(1) 양측에 배열되어 있으므로 핫런너 시스템의 두께가 얇아져서 하나의 시스템에 여러개의 노즐을 설치할 수 있는 특징이 있으며, 또한 각 노즐(6)(6')...들 사이에는 단열층(5)이 형성되어 있으므로 각 노즐간에 단열효과에 의해서 성형이 용이한 장점이 있고, 또한 다수개의 노즐(6)(6')...이 고정판(3)(3')과 방향키(4)(4')로 고정되어 있어서 다수개의 노즐(6)(6')에 의해서 대량의 플라스틱 제품을 양산할 수 있는 특징이 있는 것이다.The hot runner system connected with a plurality of nozzles 6, 6 ', etc. configured as described above is characterized in that the heaters 2, 2' of each nozzle 6, 6 '... are not coiled heaters. It is a rod heater and is arranged on both sides of the water supply (1), so the thickness of the hot runner system is thin, so that several nozzles can be installed in one system, and each nozzle (6 ... Since the insulating layer 5 is formed between them, there is an advantage that the molding is easy due to the insulating effect between the nozzles, and the plurality of nozzles 6, 6 '... and the fixing plate 3, 3' Since it is fixed by the direction keys 4 and 4 ', a large quantity of plastic products can be mass-produced by a plurality of nozzles 6 and 6'.

본 발명 다수개의 노즐(6)(6')...이 연결된 핫런너 시스템은 다수개의 노즐이 연결되어 있어서 다량의 플라스틱 제품을 단시간에 대량 생산할 수 있는 효과가 있다.The hot runner system in which the plurality of nozzles 6, 6 'is connected to the present invention is capable of mass production of a large amount of plastic products in a short time due to the connection of a plurality of nozzles.
