본 발명은 노즐바디가 이중으로 구성된 플라스틱제품 성형용 핫런너 밸브 노즐에 관한 것으로서, 특히 노즐바디를 이중으로하여 필요에 따라 노즐길이를 조절할 필요가 있을 때 특히 길게 연장할 필요가 있을 때 두 개의 노즐바디의 결합부 사이에 연장할 길이만큼의 폭을 갖는 쐐기를 설치하고 그 쐐기중 어느 하나는 두개의 노즐바디와 용접 고정한 것으로 구성된 플라스틱제품(플라스틱스) 성형용 핫런너 밸브 노즐에 관한 것이다.The present invention relates to a hot runner valve nozzle for molding a plastic product in which the nozzle body is composed of a double, in particular, when the nozzle body needs to be extended in particular when the nozzle length needs to be adjusted by double nozzle two nozzles A hot runner valve nozzle for forming a plastic product (plastics) comprising a wedge having a width extending to a length extending between the coupling parts of the body and one of the wedges is formed by welding two nozzle bodies and a welding fixture.

일반적으로 플라스틱제품 성형용 핫런너 밸브 노즐은 그 바디가 하나의 동체(100)로 되어 있기 때문에 필요에 따라서 기존의 노즐보다 더 길이가 긴 노즐이 필요할 경우에는 동일 구조이면서도 그 필요한 길이에 맞는 노즐바디를 별도로 다시 제작해야하기 때문에, 즉, 필요한 노즐의 길이에 따라 일일이 그 길이에 맞는 노즐을 제작해야하기 때문에, 금형의 제작비, 재료비 및 인건비등 별도의 제작비용이 소요되어 노즐의 제조원가가 높아지는 폐단이 있을 뿐 아니라 제작기간이 지연되는 등의 불편함도 있게 된다.In general, the hot runner valve nozzle for molding a plastic product has a single body 100, and thus, when a nozzle having a longer length than a conventional nozzle is needed, the nozzle body having the same structure and the required length is required. In other words, since it is necessary to manufacture the nozzle according to the length of the nozzle according to the required nozzle length separately, the manufacturing cost of the mold, material cost and labor costs are additionally required, resulting in increased manufacturing cost of the nozzle. In addition, there is also inconvenience such as delay in production period.

본 발명은 상기한 바와 같은 종래의 일체로된 플라스틱제품 성형용 핫런너 밸브 노즐의 원가상승 및 양산의 어려움 등 각종 불편한 결점을 해소하기 위하여 노즐의 바디를 제1 및 제2바디로 하여 제1,2노즐바디를 임의로 분해 결합하면서 필요로하는 길이에 맞게 두 개의 노즐바디 사이의 결합부위에 두개의 쐐기를 설치한 다음 노즐팁부의 분해 결합시 풀림을 방지하기 위해 두개중 하나의 쐐기와 두개의 노즐바디를 용접으로 고정한 것으로 구성됨을 특징으로한 이중노즐바디로 길이조절이 가능한 핫런너 밸브노즐을 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention provides a first body and a second body of the nozzle body in order to solve various inconveniences such as cost increase and difficulty in mass production of the conventional integrated plastic product hot runner valve nozzle. 2 Install the two wedges at the joint between the two nozzle bodies to the required length while arbitrarily disassembling the nozzle body, and then use one of the two wedges and two nozzles to prevent loosening when disassembling the nozzle tip. With a double nozzle body characterized in that the body is fixed by welding to provide a adjustable length hot runner valve nozzle as described in detail with reference to the accompanying drawings as follows.

본 발명은 노즐헤드(11)에 노즐핀 가이드부시(9)와 노즐팁부(10)에 노즐팁 부시(12)를 구비한 플라스틱제품(플라스틱스) 성형용 핫런너 밸브 노즐에 있어서,The present invention provides a hot runner valve nozzle for molding a plastic product (plastics) having a nozzle pin guide bush 9 and a nozzle tip bush 12 at a nozzle head 11.

노즐바디를 제1노즐바디(1)와 제2노즐바디(2)로 구성하되, 제1노즐바디(1)는 내부의 좌측은 좁고 중앙 내벽에는 수나사(3)가 형성되면서 우측으로 갈수록 계단식으로 점차 넓어지는 내부공간(5)을 형성한 것으로 구성하고, 제2노즐바디(2)는 상기 제1노즐바디(1)의 내부공간(5)과 일치하는 외경을 가지면서 중간 외주면에는 상기 제1노즐바디(1) 내부공간(5)의 수나사(3)와 대응결합되는 암나사(3')를 형성한 것으로 구성하여, 상기 제1노즐바디(1)의 내부공간(5)에 형성된 수나사(3)와 제2노즐바디(2)의 외표면에 형성된 암나사(3')에 의한 좌우 이동에 의해 제1,2노즐바디(1)(2)의 길이를 임의로 조절할 수 있도록 결합하되, 그 길이를 조절하기 위해서는 제1노즐바디(1) 우단(8)과 제2노즐바디(2) 우측의 단턱(4)사이에 연장할 길이만큼의 폭을 갖는 제1쐐기링(6)을 끼우고, 제1노즐바디의 내부 좌단(7)과 제2노즐바디의 좌단(7')사이에도 상기 제1쐐기링(6)과 폭은 동일하고 직경은 제2노즐바디(2)의 좌단(7)직경과 동일한 또다른 제2쐐기링(6')을 끼워 결합한 후, 상기 제1쐐기링(6)과 제1 및 2노즐바디(1)(2)를 유동되지 않게 용접하여 고정한 것으로 구성된다.
상기 제1쐐기링(6)과 제1 및 2노즐바디(1)(2)의 용접이 완료된 후, 제2노즐바디(2)에 커버(13)를 결합한다.The nozzle body is composed of a first nozzle body (1) and a second nozzle body (2), but the first nozzle body (1) has a narrow left side inside and a male screw (3) is formed on the central inner wall so that it can be stepped toward the right side. The second nozzle body 2 has an outer diameter coinciding with the inner space 5 of the first nozzle body 1 and is formed on the intermediate outer circumferential surface. A male screw 3 formed in the inner space 5 of the first nozzle body 1 by forming a female screw 3 'correspondingly coupled to the male screw 3 of the nozzle body 1 of the inner space 5. ) And the length of the first and second nozzle body (1) (2) by the left and right movement by the female screw (3 ') formed on the outer surface of the second nozzle body (2) can be arbitrarily adjusted. To adjust, insert a first wedge ring 6 having a width as long as an extension between the right end 8 of the first nozzle body 1 and the step 4 of the right side of the second nozzle body 2, Even between the inner left end 7 of the first nozzle body and the left end 7 'of the second nozzle body, the first wedge ring 6 has the same width and the diameter of the left end 7 of the second nozzle body 2. After fitting the other second wedge ring (6 ') of the same diameter, it is composed of the first wedge ring 6 and the first and second nozzle body (1) (2) fixed by welding so as not to flow.
After the welding of the first wedge ring 6 and the first and second nozzle bodies 1 and 2 is completed, the cover 13 is coupled to the second nozzle body 2.

이상과 같이 구성되는 본 발명 핫런너 밸브 노즐은 두 개의 동체(제1,2노즐바디)로 구성되어 있어서 한의 표준크기의 모델만 제작해두게 되면 더 이상 길이를 늘릴 필요가 없을 때는 현상대로 두 개의 노즐동체를 결합하여 사용하면 되고 필요에 따라 그 길이를 연장, 조절해야할 경우에는 제1노즐바디(1)의 우단(8)과 제2노즐바디(2)의 단턱(4)사이에 연장할 길이만큼의 폭을 가진 제1쐐기링(6)을 끼우고, 제1노즐바디의 내부공간(5)의 좌단(7)과 제2노즐바디의 좌단(7')사이에도 상기 제1쐐기링(6)과 폭은 동일하고 제2노즐바디의 좌단(7)직경과 동일한 또다른 제2쐐기링(6')을 끼워 결합한 후, 상기 제1쐐기링을 제1 및 제2노즐바디(1)(2)와 용접 고정해주므로써, 노즐팁부(10)의 노즐팁 부시(12)를 분해, 결합시 제1 및 제2노즐바디(1)(2)가 그것들의 암수나사(3)(3')에 의해서 풀리지 않고 요동되지 않으면서 결합되어 노즐의 길이가 조절된 상태로 사용할 수 있게 되므로 한가지 일정길이의 제1,2노즐바디(1)(2)를 대량으로 확보해두기만 하면 일일이 길이가 다른 노즐이 필요할때에도 노즐을 다시 생산할 필요없이 연장할 만큼의 길이를 갖는 제1,2쐐기링(6)(6')만을 선택하여 제1,2노즐바디(1)(2) 사이에 끼워 조립하면 자연스럽게 필요한 길이로 조절된 노즐바디를 사용할 수 있게 되는 장점이 있는 것이다.The hot runner valve nozzle of the present invention configured as described above is composed of two fuselage bodies (first and second nozzle bodies). The nozzle body may be used in combination. If necessary, the length of the nozzle body may be extended between the right end 8 of the first nozzle body 1 and the step 4 of the second nozzle body 2. The first wedge ring 6 having a width corresponding to the width of the first wedge ring 6 is inserted between the left end 7 of the inner space 5 of the first nozzle body and the left end 7 'of the second nozzle body ( 6) after fitting another second wedge ring 6 'having the same width and the same diameter as the left end 7 of the second nozzle body, the first wedge ring is connected to the first and second nozzle bodies 1). (2), the first and second nozzle bodies (1) and (2) have their male and female screws (3) (3 ') when disassembling and joining the nozzle tip bush (12) of the nozzle tip (10). Of) Since it can be combined without being loosened and not swinged, it can be used in a state in which the length of the nozzle is adjusted, so as to secure a large amount of the first and second nozzle bodies 1 and 2 of one length, nozzles of different lengths Even when this is necessary, it is natural to select only the first and second wedge rings (6) and 6 'that have a length enough to extend without having to produce the nozzle again, and sandwich them between the first and second nozzle bodies (1) and (2). The advantage is that the nozzle body can be adjusted to the required length.

상기한 바와 같은 본 발명 핫런너 밸브 노즐은 필요한 길이에 따라 일일이 노즐을 새로이 제작하지 않고도 제1,2쐐기링(6)(6')으로 길이를 조절하면 되므로 노즐의 길이조절원가가 저렴한데다가 제품도 단시간에 양산할 수가 있어서 더욱 경제적인 효과가 있다.The hot runner valve nozzle of the present invention as described above can adjust the length with the first and second wedge rings (6) (6 ') without having to make a new nozzle one by one according to the required length. Even mass production in a short time, there is a more economic effect.
