Description

금형{MOLD}Mold {MOLD}

본 발명은 금형에 관한 것으로, 더욱 상세하게는 고주파 유도가열 방식을 통해 가열되어 일정 온도를 유지할 수 있는 금형에 관한 것이다. The present invention relates to a mold, and more particularly, to a mold capable of maintaining a constant temperature by heating through a high frequency induction heating method.

일반적으로 금형은 서로 결합되어 사이에 제조될 물건과 대응하는 형상의 캐비티가 형성되는 한 쌍의 금형을 포함한 것으로, 각 금형은 각각 제조될 물건과 대응하는 형상의 금형면이 마련되어 있는 한 쌍의 코어와, 한 쌍의 코어가 각각 안착지지되는 한 쌍의 몰드베이스를 포함하여, 한 쌍의 코어에 각각 마련되어 있는 두 금형면에 의해 형성되는 캐비티 내에 용융 수지나 용융 금속과 같은 용융 물질을 주입한 후 응고시켜 물건을 제조하도록 되어 있다. In general, a mold includes a pair of molds that are coupled to each other to form a cavity of a shape corresponding to the object to be manufactured therebetween, each mold having a pair of cores each having a mold surface of a shape corresponding to the object to be manufactured. And a molten material such as molten resin or molten metal in the cavity formed by the two mold surfaces provided on the pair of cores, respectively, including a pair of mold bases on which the pair of cores are respectively seated and supported. It is intended to solidify and produce things.

근래 이러한 금형 중에는 고주파 유도가열 방식으로 코어를 가열하여 코어가 일정 온도로 유지될 수 있도록 한 금형이 있다.Recently, among these molds, there is a mold in which the core is heated by a high frequency induction heating method so that the core can be maintained at a constant temperature.

고주파 유도가열 방식을 적용한 금형은 코어에 고주파 교류 전류를 전달받아 자기장을 발생시키는 고주파 코일을 배치하여 고주파 코일에서 발생한 자기장에 의해 코어에서 와전류 및 와전류 손실에 의한 열이 발생되게 함으로써 코어가 일정 온도로 가열될 수 있게 한다. The mold adopting the high frequency induction heating method arranges the high frequency coil which receives the high frequency alternating current to generate the magnetic field and generates heat by the eddy current and eddy current loss in the core by the magnetic field generated by the high frequency coil. Allow to be heated.

그런데 이러한 종래의 금형에 있어서, 자기장은 고주파 코일을 중심으로 양측에 대칭되게 형성되므로, 금형의 코어뿐만 아니라 가열할 필요가 없는 몰드베이스에서도 와전류 및 와전류 손실에 의한 열이 발생하여, 이에 의한 열손실이 발생한다는 문제점이 있다. However, in such a conventional mold, since the magnetic field is formed symmetrically on both sides of the high frequency coil, heat is generated by the eddy current and the eddy current loss not only in the core of the mold but also in the mold base that does not need to be heated, and thus heat loss. There is a problem that this occurs.

본 발명은 상술한 종래기술의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 보다 효율적으로 고주파 유도가열 방식으로 코어를 가열할 수 있는 금형을 제공하는 것이다. The present invention is to solve the above problems of the prior art, an object of the present invention to provide a mold capable of heating the core in a high frequency induction heating method more efficiently.

상술한 목적을 달성하기 위한 본 발명에 따른 금형은 고주파 교류 전류가 흐르는 고주파 코일과, 상기 고주파 코일에서 발생한 자기장을 일측으로 편향시키는 자성코어를 포함하는 것을 특징으로 한다. The mold according to the present invention for achieving the above object is characterized in that it comprises a high frequency coil through which a high frequency alternating current flows, and a magnetic core for deflecting the magnetic field generated in the high frequency coil to one side.

또한, 제조될 물건과 대응하는 형상의 금형면이 마련된 코어와, 상기 코어를 지지하는 몰드베이스를 더 포함하며, 상기 고주파 코일에서 발생하는 자기장이 상기 자성코어에 의해 상기 금형면측으로 편향되는 것을 특징으로 한다. The apparatus may further include a core provided with a mold surface having a shape corresponding to the object to be manufactured, and a mold base supporting the core, wherein a magnetic field generated in the high frequency coil is biased toward the mold surface by the magnetic core. It is done.

또한, 상기 코어에는 상기 고주파 코일과 상기 자성코어가 수용되는 코일 설치부가 마련되는 것을 특징으로 한다. In addition, the core is provided with a coil installation unit for receiving the high frequency coil and the magnetic core.

또한, 상기 자성코어는 상기 고주파 코일의 상기 금형면측을 제외한 방향을 덮도록 형성되는 것을 특징으로 한다. In addition, the magnetic core is characterized in that it is formed to cover the direction except the mold surface side of the high frequency coil.

또한, 상기 자성코어는 일측으로 개방된 ㄷ자 형상 단면으로 형성되며 그 개방되어 있는 측 단부가 상기 금형면측을 향하도록 배치되는 것을 특징으로 한다. In addition, the magnetic core is formed of a U-shaped cross-section open to one side and is characterized in that the open side end is disposed so as to face the mold surface side.

또한, 상기 코어에는 냉각유체가 흐르는 냉각채널이 형성되는 것을 특징으로 한다. In addition, the core is characterized in that the cooling channel through which the cooling fluid flows is formed.

이상에서 상세히 설명한 바와 같이 본 발명에 따른 금형은 고주파 코일에서 발생한 자기장이 자성코어에 의해 금형면이 형성되어 있는 방향으로 편향되어 자기장에 의한 와전류 및 와전류 손실에 의한 열의 발생은 대부분 코어에서 발생하게 되므로, 보다 효율적으로 코어가 가열될 수 있게 되는 효과가 있다. As described in detail above, in the mold according to the present invention, the magnetic field generated in the high frequency coil is deflected in the direction in which the mold surface is formed by the magnetic core, so that the generation of heat due to the eddy current and the eddy current loss caused by the magnetic field is mostly generated in the core. Therefore, there is an effect that the core can be heated more efficiently.
