It relates to a hot water cooling structure of an injection mold.

일반적으로 소정의 형상을 갖는 제품을 성형할 때에는 사출금형을 이용하고 있으며, 이러한 사출금형은 도1에 나타낸 바와 같이 수지가 공급되는 공급공(11)이 형성된 고정형판(10)과, 상기 고정형판(10)의 하부에 이동 가능하게 설치된 가동형판(20)이 마련되어 있고, 상기 고정형판(10) 및 가동형판(20)의 사이에는 제품이 생산될 수 있도록 수지가 유입되는 성형홈(30)이 형성되어 있다.In general, an injection mold is used to mold a product having a predetermined shape. The injection mold includes a fixed mold plate 10 having a supply hole 11 through which resin is supplied, and a fixed mold plate as shown in FIG. The movable die plate 20 is provided to be movable in the lower portion of the 10, and between the stationary die plate 10 and the movable die plate 20, a molding groove 30 into which resin is introduced so that a product can be produced. Formed.

한편, 상기 성형홈(30)의 일측에는 공급공(11)을 통하여 공급되는 수지가 유입될 수 있도록 탕구(40)가 연결되어 있다.On the other hand, one side of the molding groove 30 is connected to the spout 40 so that the resin supplied through the supply hole 11 can be introduced.

그리고 상기 고정형판(10)에는 고온의 수지를 공급함에 따라서 가열되는 고정형판(10)을 냉각시키도록 냉각수가 순환되는 냉각수 순환공(12)이 형성되어 있다.The fixed mold plate 10 has a coolant circulation hole 12 through which coolant is circulated so as to cool the fixed mold plate 10 that is heated by supplying a high temperature resin.

따라서, 제품을 성형할 때에는 가동형판(20)이 고정형판(10)의 저면에 근접되도록 상기 가동형판(20)을 상부로 이동시킨 후 소정이 온도로 가열되어 용융된 수지를 고정형판(10)에 형성된 공급공(11)을 통하여 공급시킨다.Therefore, when molding the product, the movable plate 20 is moved upward so that the movable plate 20 is close to the bottom surface of the stationary plate 10, and then the molten resin is heated to a predetermined temperature and the molten resin is fixed to the plate 10. It is supplied through the supply hole 11 formed in the.

이와 같이 공급공(11)을 통하여 공급된 수지는 탕구(40)를 통하여 고정형판(10)과 가동형판(20)의 사이에 형성된 성형홈(30)의 내부로 유입된다.The resin supplied through the supply hole 11 is introduced into the molding groove 30 formed between the stationary plate 10 and the movable plate 20 through the spout 40.

It is formed, the end of the cooling hole 51 is provided with a temperature controller 70 for controlling the temperature of the cooling water.

이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

먼저, 제품을 성형할 때에는 가동형판(20)이 고정형판(10)의 저면에 근접되도록 상기 가동형판(20)을 상부로 이동시킨 후 소정이 온도로 가열되어 용융된 수 지를 고정형판(10)에 형성된 공급공(11)을 통하여 공급시킨다.First, when molding a product, the movable plate 20 is moved upward so that the movable plate 20 is close to the bottom surface of the stationary plate 10, and then the molten resin is heated to a predetermined temperature to fix the molten resin. It is supplied through the supply hole 11 formed in the.

이와 같이 공급공(11)을 통하여 공급된 수지는 탕구(40)를 통하여 고정형판(10)과 가동형판(20)의 사이에 형성된 성형홈(30)의 내부로 유입된다.The resin supplied through the supply hole 11 is introduced into the molding groove 30 formed between the stationary plate 10 and the movable plate 20 through the spout 40.

상기 성형홈(30)의 내부로 수지가 유입되면 고정형판(10)에 형성된 냉각수 순환공(12)으로 냉각수를 순환시켜 용융상태의 수지를 냉각시킴과 동시에 탕구(40)의 하부에 설치된 냉각블럭(50)의 냉각공(51)을 냉각수를 공급시켜 탕구(40)에 유입된 수지를 냉각시킨다.When the resin flows into the molding groove 30, the cooling water is circulated to the cooling water circulation hole 12 formed in the fixed mold plate 10 to cool the resin in the molten state and at the same time, a cooling block installed in the lower portion of the spout 40. Cooling water is supplied to the cooling holes 51 of 50 to cool the resin introduced into the pouring port 40.

이때 상기 냉각공(51)을 통하여 공급되는 냉각수는 탕구(40)에 유입된 수지를 신속하게 냉각시킬 수 있도록 온도조절기(70)에서 온도가 조절된 상태로 공급되는 것이다.At this time, the cooling water supplied through the cooling hole 51 is supplied in a state in which the temperature is controlled in the temperature controller 70 so as to quickly cool the resin introduced into the pouring hole 40.
