Description
본 고안은 사출금형에 관한 것으로, 더욱 상세하게는 냉각분배기를 금형에 결합시켜 사출금형의 작업공정시간을 절약하여 생산성을 향상시킬 수 있는 냉각수분배기가 결합된 사출금형에 관한 것이다.The present invention relates to an injection mold, and more particularly, to an injection mold combined with a cooling water distributor that can improve the productivity by coupling the cooling distributor to the mold, thereby reducing the working time of the injection mold.
사출성형기는 호퍼에서 주입되는 용탕을 금형의 캐비티에 충전시켜 일정한 냉각기간을 거쳐 용탕을 고화시킨 후에 금형의 가동판과 고정판을 분리시켜 사출제품을 생산할 수 있다.The injection molding machine may produce an injection product by filling the molten metal injected from the hopper into the cavity of the mold to solidify the molten metal through a predetermined cooling period and then separating the movable plate and the fixed plate of the mold.
이러한 금형은 용탕을 고화시키는 과정에서 용탕이 응고되는 온도구배를 일정하게 유지되도록 성형품의 살두께가 불균일한 경우에 두께가 두꺼운 부위가 얇은 부위와 균일한 냉각속도를 갖도록 금형에 냉각홀을 형성하고, 그 냉각홀에 냉각수를 순환시켜 용탕이 응고되도록 설계하고 있다. 냉각수의 구멍은 대형금형일수록 증가되어 사출기에서 연결되는 메인호스에서 각각의 냉각홀로 외부에서 냉각수를 공급시키는 냉각수분배기가 결합되는 것이 필수적이다.In the mold, the cooling hole is formed in the mold to have a thin portion and a uniform cooling rate in the case where the thickness of the molded product is uneven so that the temperature gradient during which the molten metal is solidified is kept constant. In addition, the cooling water is circulated in the cooling hole to melt the molten metal. The hole of the coolant increases as the large mold increases, and it is essential to combine the coolant distributor for supplying coolant from the outside to each cooling hole in the main hose connected to the injection machine.
이와같은 냉각수분배기가 결합된 금형을 도면을 참조하여 살펴보면 다음과 같다.Looking at the mold combined with such a coolant distributor as follows.
도 1을 참조하면, 종래의 냉각수분배기가 결합된 상태의 개략적이 사시도가 도시되어 있는데, 참조번호 10은 가동판과 고정판으로 구성되는 금형이고, 20a,20b는 메인호스(30)가 연결된 냉각수분배기이다.Referring to Figure 1, a schematic perspective view of a conventional cooling water distributor coupled state is shown, reference numeral 10 is a mold consisting of a movable plate and a fixed plate, 20a, 20b is a cooling water distributor connected to the main hose 30 to be.
금형(10)은 도 2에 도시된 바와 같이 고정판과 가동판이 다단으로 구비되어, 용탕이 충전되는 캐비티(16)가 형성된 고정측형판(12)과 가동측형판(14)이 서로 대칭되도록 결합시켜 캐비티(16)에 용탕이 주입된다. 고정측형판(12)과 가동측형판(14)에는 캐비티(16)와 일정거리 이격되게 냉각홀(18)이 형성된다. 냉각홀(18)은 냉각수가 주입되어 순환되는 유로로, 금형의 외부와 통해져 있다. 또한 냉각홀(18)에는 냉각호스(28)가 연결되는 엘보(29)가 결합되어 있다.As shown in FIG. 2, the mold 10 includes a fixed plate and a movable plate in multiple stages, such that the fixed side plate 12 and the movable side plate 14 having the cavity 16 filled with the molten metal are symmetrically coupled to each other. Melt is injected into the cavity 16. Cooling holes 18 are formed in the fixed side plate 12 and the movable side plate 14 to be spaced apart from the cavity 16 by a predetermined distance. The cooling hole 18 is a flow path through which coolant is injected and circulated through the outside of the mold. In addition, the elbow 29 to which the cooling hose 28 is connected is coupled to the cooling hole 18.
냉각수분배기(20a,20b)는 고정측형판(12)과 가동측형판(14)의 각각에 냉각수를 순환시키는 주입구(22)와 배출구(24)가 형성된 각각의 냉각수분배기(20a,20b)가 분리되어 결합되어 있고, 외부표면에는 냉각수를 금형(10)에 공급하는 분배구(26)가 형성되어 있다. 그리고, 냉각수분배기(20a,20b))의 주입구(22)와 배출구(24)에는 도면에는 도시되지 않았으나, 사출기와 연결된 메인호스(30)가 결합되어 있다. 이와 같이 구성되는 금형(10)은 고정측형판(12)과 가동측형판(14)을 결합하여 캐비티(16)로 용탕을 주입하고, 냉각수분배기(20a,20b)의 분배구(26)에 결합된 냉각호스(28)를 각각의 냉각홀(18)에 결합시켜 메인호스(30)를 통해 공급된 냉각수를 냉각홀(18)로 순환시켜 사출제품의 온도구배를 일정하게 유지하도록 하여 고화시킨다. 그리고 고화된 사출제품을 고정판과 가동판을 분리시켜 캐비티(16)내에서 형성된 사출제품을 생산하게 된다.The cooling water distributors 20a and 20b are separated from each of the cooling water distributors 20a and 20b having the inlet 22 and the outlet 24 for circulating the cooling water in each of the fixed side plate 12 and the movable side plate 14. And a distribution port 26 for supplying cooling water to the mold 10 on the outer surface thereof. In addition, although not shown in the drawing, the inlet 22 and the outlet 24 of the cooling water distributors 20a and 20b are coupled to the main hose 30 connected to the injection machine. The mold 10 configured as described above combines the fixed side plate 12 and the movable side plate 14 to inject molten metal into the cavity 16, and is coupled to the distribution holes 26 of the cooling water distributors 20a and 20b. The cooling hose 28 is coupled to each cooling hole 18 to circulate the cooling water supplied through the main hose 30 to the cooling hole 18 so as to maintain a constant temperature gradient of the injected product. The solidified injection product is separated from the fixed plate and the movable plate to produce an injection product formed in the cavity 16.
그러나, 제품을 사출성형시에 금형을 조립하는 과정에서 냉각수를 공급할 때, 특히 대형 금형일 경우에는 냉각수 구멍이 다량으로 형성되어 있기 때문에 냉각수분배기에서 냉각수 구멍으로 각각에 냉각호스를 연결하고, 또한, 사출제품을 완성된 후에 각각 금형으로 부터 냉각호스를 분리시키는데 소요되는 시간이 길어 생산성이 떨어지는 폐단이 있다.However, when supplying the cooling water in the process of assembling the mold during the injection molding of the product, especially in the case of a large mold, since a large amount of cooling water holes are formed, a cooling hose is connected to each of the cooling water holes in the cooling water distributor. After finishing the product, it takes a long time to separate the cooling hose from the mold, which leads to a decrease in productivity.

In the cooling water distributor 20, a plurality of distribution holes 26 are formed on an outer surface thereof, and a cooling hose 28 connected to the cooling hole 18 as described in FIG. 2 is coupled to the elbow 29.
이와 같이 구성된 본 고안의 작동상태 및 작용효과를 살펴보면 다음과 같다.Looking at the operating state and the effect of the present invention configured as described above are as follows.
도 3에 도시된 바와 같이 냉각홀(18)이 형성된 고정측형판(12)과 가동측형판(14)의 일측면에 냉각수분배기(20)가 결합되고, 냉각수분배기(20)의 분배구(26)에 결합된 냉각호스(28)가 금형(10)의 냉각홀(18)에 일체로 결합된다. 그리고, 냉각수분배기(20)의 주입구(22)와 배출구(24)에 결합된 니플(32)에 메인호스(30)가 결합분리 가능하도록 결합된다.As shown in FIG. 3, the cooling water distributor 20 is coupled to one side of the fixed side plate 12 and the movable side plate 14 on which the cooling holes 18 are formed, and the distribution port 26 of the cooling water distributor 20. Cooling hose 28 coupled to the) is integrally coupled to the cooling hole 18 of the mold (10).
