Description
본 발명은 용융된 수지를 금형의 게이트에 사출 성형하는 핫런너의 노즐용 팁에 관한 것이다.The present invention relates to a tip for a nozzle of a hot runner for injection molding molten resin into a gate of a mold.
일반적으로 사출기용 핫런너 노즐은 금형의 게이트와 동일한 좌표에 설치하여 사출기에서 공급되는 수지를 금형의 게이트에 사출하는데 사용된다.In general, the hot runner nozzle for the injection molding machine is installed at the same coordinate as the gate of the mold, and used to inject the resin supplied from the injection molding machine to the gate of the mold.
그리고 사출기용 노즐의 끝 부분에는 금형의 게이트와 접하는 부분에 팁이 설치되어 사용되고 있다.The tip of the nozzle for the injection molding machine is used to contact the gate of the mold.
하지만 고온의 안정된 온도를 유지시켜야 하는 핫런너에서 노즐은 히터가 체결되어 발열을 유지하지만 그 노즐에 조립되는 팁은 개별적으로 장착되는 히터가 없이 노즐에서 전달되는 열만으로 안정적인 온도를 유지해야 한다. However, in a hot runner that needs to maintain a stable temperature at a high temperature, the nozzle is connected to the heater to maintain heat, but the tip assembled to the nozzle needs to maintain a stable temperature only by heat transferred from the nozzle without a heater mounted separately.
종래에 사용되어온 팁은 강으로 된 소재와 동이나 동합금 및 스테인리스를 소재로 하는 팁으로 된 팁이 주종을 이루고 있다.Conventionally used tips are mainly made of a steel material and a tip made of copper or copper alloy and stainless steel.
상기 전자의 스테인레스 및 강 소재로 된 팁은 내마모성 및 내부식성에 우수 하고 경도가 높은 장점이 있으나 열전도가 낮은 단점이 있다.The tip made of stainless steel and steel of the former has the advantages of excellent wear resistance and corrosion resistance and high hardness, but low heat conductivity.
이와 같이 노즐용 팀에 열전도가 낮을 경우 노즐과 팁을 통과하여 이송되는 수지가 고화가 발생하는 단점이 있으며, 이로 인하여 팁의 내부에 고화 현상으로 인하여 사출이 안되거나 잔류 수지가 남게 되는 단점이 있다.As such, when the thermal conductivity of the nozzle team is low, the resin transferred through the nozzle and the tip has a disadvantage of solidification, and thus, there is a disadvantage in that no injection or residual resin remains due to the solidification phenomenon inside the tip. .
상기와 같이 잔류수지가 발생할 경우 사출용 수지의 컬러를 교체할 때 고화현상으로 인하여 잔류 된 수지가 교체된 새로운 수지와 혼합되어 사출됨으로 불량이 발생하게 되는 단점이 있다.When the residual resin occurs as described above, when the color of the injection resin is replaced, there is a disadvantage in that a defect occurs because the residual resin is mixed with the new resin which is replaced due to solidification.
한편, 동 계열의 소재로 된 팁은 강 소재에서 떨어지는 열 전도성을 보완하기 위해 사용된 것으로, 팁의 끝단까지 열전달이 빠르고 안정적인 장점이 있으나 내마모성 및 내부식성이 떨어지는 문제점이 있다.On the other hand, the tip of the material of the series is used to complement the thermal conductivity falling from the steel material, heat transfer to the tip of the tip has the advantage of fast and stable, but there is a problem of low wear resistance and corrosion resistance.
상기와 같이 팁이 내마모성 및 내부식성이 떨어질 경우 팁의 마모가 심하여 수명이 짧고, 이로 인하여 잦은 교체를 하여야 하는 단점이 있다. As described above, when the tip has abrasion resistance and corrosion resistance, the tip wears severely, resulting in a short life, and thus, frequent replacement is required.
기타 특수합금 등 소재 자체로 내모마성과 내부식성, 열전도를 우수하게 제작한 팁은 특성은 우수하나 가공성이 나쁘거나 고가의 제작 단가 등의 문제점이 있다.The tip produced with excellent wear resistance, corrosion resistance and heat conduction by other special alloy materials itself is excellent in properties, but has poor workability or expensive manufacturing cost.
본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 노즐에 체결되는 팁을 강도가 좋고, 열전도가 빠르며 내마모성 및 내부식성이 우수하도록 하는데 그 목적이 있다.The present invention has been invented to solve the above problems, the purpose of the tip fastened to the nozzle to have good strength, fast thermal conductivity and excellent wear resistance and corrosion resistance.
본 발명의 다른 부가적인 목적으로는 팁의 제조단가를 절감할 수 있도록 하는데 그 목적이 있다. Another additional object of the present invention is to reduce the manufacturing cost of the tip.
상기의 과제를 해결하기 위한 수단으로 수지의 흐름과 직접적인 연관이 있는 내경부의 팁은 강으로 된 소재로 하여 안정적인 내마모성을 이루도록 하고, 그 외벽에 열전도가 빠른 동계열의 금속으로 된 열전도체를 설치함으로써 해소할 수가 있다.As a means to solve the above problems, the tip of the inner diameter part directly related to the flow of the resin is made of a steel material to achieve a stable wear resistance, and a heat conductor made of a copper-based metal having high thermal conductivity on the outer wall is installed. This can be solved.
또한 동계열의 소재의 부식을 방지하고 보완하기 위하여 그 외벽에 스테인레스등의 소재를 설치하여 내마모성 및 내부식성 그리고 열전도를 향상시킬 수 있다.In addition, in order to prevent and supplement corrosion of materials of the copper series, stainless steel materials can be installed on the outer wall to improve wear resistance, corrosion resistance, and thermal conductivity.
상기와 같이 된 본 발명은 구조가 간단하고 가공성이 우수하여 제작이 용이하고 팁의 열전도가 빠르므로 수지가 팁에서 고화되는 것을 방지할 수가 있고, 내마모성과 내부식성이 우수하므로 팁의 수명을 최대로 연장할 수가 있는 것이다.The present invention as described above is simple in structure and excellent in workability, easy to manufacture and fast heat conduction of the tip can prevent the resin from solidifying on the tip, and excellent wear resistance and corrosion resistance to maximize the life of the tip It can be extended.
노즐(13)의 하단부(14)에 체결되며 내부에 밸브 핀이 조립되고, 실린더(11)의 작동에 의하여 밸브 핀이 상하 작동하면서 수지를 금형의 게이트로 사출하는 팁에 있어서, In the tip which is fastened to the lower end portion 14 of the

상기와 같이 된 본 발명의 작동을 설명하면 다음과 같다.Referring to the operation of the present invention as described above is as follows.
도 1은 본 발명의 전체 분리 사시도이고, 도 2는 본 발명의 결합상태를 보인 개략 사시도이며, 도 3은 본 발명의 결합상태를 보인 정면도이고, 도 4는 본 발명의 사용상태를 보인 개략 단면도이며, 도 5는 종래의 팁을 보인 개략 측 단면도를 보인 것이다.Figure 1 is an overall separated perspective view of the present invention, Figure 2 is a schematic perspective view showing a combined state of the present invention, Figure 3 is a front view showing a combined state of the present invention, Figure 4 is a schematic cross-sectional view showing a use state of the present invention. 5 is a schematic side cross-sectional view showing a conventional tip.
도 1에서와 같이 팁 몸체의(2) 외부에 열전도가 빠른 동 계열의 소재로 제작된 열전도체(3)를 팁 몸체(2)의 외부에 체결하고, 그 외측에 내부식성이 강한 파이프(4)를 체결하여 노즐의 하단부에 조립한다.As shown in FIG. 1, a
상기와 같은 상태에서 사출기가 노즐을 통하여 수지를 사출하게 되면 핫런너에 설치된 실린더가 작동하여 밸브 핀을 상하 작동시키게 되고 이로 인하여 노즐의 끝 부분에 설치된 팁의 유로가 열고 닫히면서 수지가 사출하게 된다.When the injection machine injects the resin through the nozzle in the above state, the cylinder installed in the hot runner operates to operate the valve pin up and down, thereby opening and closing the flow path of the tip installed at the end of the nozzle to inject the resin. .
이때 노즐의 끝 부분에 설치된 팁(1)은 노즐에 설치된 히터와 수지가 사출되면서 전달되는 열을 팁 몸체(2)의 외측에 체결된 열전도체(3)에 의하여 팁 몸체(2) 전체로 전달되고 이로 인하여 팁 몸체(2)가 일정한 온도를 유지하게 됨으로써 수지의 고화를 방지할 수가 있는 것이다.At this time, the
그리고 팁 몸체(2)가 내마모성이 강한 금속으로 이루어져 있기 때문에 팁 몸체(2)의 마모를 최소로 하여 수명을 연장하고, 팀 몸체(2)의 외부에 체결된 파이프(4) 또한, 내 부식성이 강하므로 수지에서 발생하는 가스나 각종 이물질로부터 부식을 방지하게 됨으로써 팁(1)의 수명을 최고로 연장할 수가 있는 유용한 발명이다.In addition, since the
