본 발명은 사출금형의 냉각 칸막이에 관한 것으로서, 더 상세하게는 상부금 형 또는 하부금형에 마련된 냉각홀에 냉각수가 흐를 수 있는 유입통로와 유출통로를 형성하여 냉각효율을 높일 수 있는 사출금형의 냉각 칸막이에 관한 것이다.The present invention relates to a cooling partition of an injection mold, and more particularly, to form an inlet passage and an outflow passage through which cooling water can flow in a cooling hole provided in an upper mold or a lower mold, thereby cooling the injection mold. It's about partitions.

일반적으로 사출성형이란 용융된 플라스틱 수지를 금형의 캐비티 내로 주입시킨 다음 이를 냉각시켜 특정 형태의 제품을 생산하는 것으로서, 이때 성형되는 제품의 품질은 사출 속도와 사출 압력, 용융 수지의 온도, 금형의 온도 등에 의해서 결정되며, 사출 성형이 이루어질 때, 금형의 온도가 지나치게 높거나 낮은 경우에 성형 불량이 발생될 확률이 매우 높아진다.In general, injection molding is injecting molten plastic resin into a cavity of a mold and then cooling it to produce a specific type of product. The quality of the molded product is injection speed, injection pressure, molten resin temperature, and mold temperature. And the like, and when the injection molding is performed, the probability of molding failure is very high when the temperature of the mold is too high or too low.

따라서 금형의 온도를 적정하게 유지시키기 위해서 금형의 내부에는 냉각수가 통과할 수 있는 냉각홀을 형성하고, 이 냉각홀에 냉각수를 유입하여 금형의 온도를 적정수준으로 유지시킬 필요가 있다.Therefore, in order to maintain the temperature of the mold properly, it is necessary to form a cooling hole through which cooling water can pass, and to keep the temperature of the mold at an appropriate level by introducing cooling water into the cooling hole.

종래에는 이렇게 냉각수가 흐를 수 있는 냉각홀을 형성하는 과정이 다음과 같았다.Conventionally, the process of forming the cooling holes through which the coolant flows was as follows.

먼저 금형의 일측에 냉각수가 금형의 내측으로 유입될 수 있도록 유입통로가 되는 제1 냉각홀을 형성한다. 또한 제1 냉각홀과 일정거리 이격된 지점에 냉각수가 배출될 수 있도록 냉각수의 유출통로가 되는 제2 냉각홀을 형성한다. 제1, 제2 냉각홀이 형성되면, 금형의 측면에서 상기 제1 냉각홀과 제2 냉각홀을 연통시키는 제3 냉각홀을 형성하고, 제3 냉각홀의 입구측은 냉각수의 누수가 방지되도록 밀봉한다.First, a first cooling hole is formed on one side of the mold to be an inflow passage so that the cooling water may flow into the mold. In addition, the second cooling hole is formed as an outlet of the cooling water so that the cooling water can be discharged to the point spaced apart from the first cooling hole a predetermined distance. When the first and second cooling holes are formed, a third cooling hole is formed on the side of the mold to communicate the first cooling hole and the second cooling hole, and the inlet side of the third cooling hole is sealed to prevent leakage of cooling water. .

이렇게 하나의 냉각수 이동 경로를 형성하기 위해 적어도 3번의 드릴링 작업과 제3 냉각홀의 밀봉작업이 이루어져야 하므로 작업 공정이 복잡해지고 이에 따라 금형의 제작단가가 상승하게 되는 폐해가 있었다.Since at least three drilling operations and a sealing operation of the third cooling hole have to be performed to form one coolant movement path, the work process is complicated and the manufacturing cost of the mold increases.

특히 하나의 금형에 복수개의 냉각수 이동 경로를 형성하기 위해 복수개의 냉각홀을 형성하는 경우에는 그 제작이 매우 번거로우며, 금형의 제작 단가 역시 매우 급격히 상승하게 되었다.In particular, in the case where a plurality of cooling holes are formed to form a plurality of cooling water movement paths in one mold, the fabrication thereof is very cumbersome, and the manufacturing cost of the mold also increases rapidly.

이렇게 구성된 본 발명에 따른 사출금형의 냉각 칸막이(10)를 이용한 금형의 냉각과정을 설명하면 다음과 같다.Referring to the cooling process of the mold using the cooling partition 10 of the injection mold according to the present invention configured as follows.

먼저 금형에 마련된 냉각홀(3)에 격판(11)을 체결한다. 격판(11)은 냉각수 통과홈(12)이 냉각홀(3)의 내측으로 인입되도록 체결하며, 결합부(13)가 형성된 측은 냉각홀(3)의 입구측에 위치시킨다.First, the diaphragm 11 is fastened to the cooling hole 3 provided in the metal mold | die. The diaphragm 11 is fastened so that the cooling water passage groove 12 enters into the cooling hole 3, and the side in which the coupling part 13 is formed is positioned at the inlet side of the cooling hole 3.

격판(11)의 체결이 완성되면 냉각홀(3)의 입구에 실링부재(14)를 설치한다. 실링부재(14)의 외주면은 냉각홀(3)이 형성된 하부금형(1)의 내면과 접촉되고, 실링부재(14)의 내주면의 내측으로 격판(11)의 결합부(13)가 위치한다. 실링부재(14)의 내경은 결합부(13)의 폭보다 조금 크게 형성되어 있으므로 결합부(13)와 실링부재(14)의 체결이 용이하게 이루어진다.When the fastening of the diaphragm 11 is completed, the sealing member 14 is installed at the inlet of the cooling hole 3. The outer circumferential surface of the sealing member 14 is in contact with the inner surface of the lower mold 1 in which the cooling hole 3 is formed, and the engaging portion 13 of the diaphragm 11 is positioned inside the inner circumferential surface of the sealing member 14. Since the inner diameter of the sealing member 14 is formed to be slightly larger than the width of the coupling portion 13, the coupling portion 13 and the sealing member 14 are easily coupled.

실링부재(14)의 설치가 완료되면 결합부재(17)를 콜릿부(16)에 체결하여 격판(11)의 결합부(13)와 실링부재(14)를 견고하게 밀착시킨다. 결합부재(17)는 테이퍼져 있기 때문에 콜릿부(16)에 인입될수록 콜릿부(16)를 외측으로 확장시키게 되며, 콜릿부(16)의 확장에 따라 콜릿부(16)의 외주면에 연결된 격판(11)의 결합부(13)가 외측으로 이동하게된다. 결합부(13)의 이동으로인해 결합부(13)가 실링부재(14)의 내면과 접촉 및 가압됨으로써 결합부(13)는 실링부재(14)에 견고하게 밀 착 결합된다.When the installation of the sealing member 14 is completed, the coupling member 17 is fastened to the collet part 16 so that the coupling part 13 of the diaphragm 11 and the sealing member 14 are tightly adhered to each other. Since the coupling member 17 is tapered, the collet part 16 extends outward as it enters the collet part 16, and the diaphragm connected to the outer circumferential surface of the collet part 16 according to the expansion of the collet part 16. The engaging portion 13 of 11 is moved outward. Due to the movement of the coupling portion 13, the coupling portion 13 is in contact with and pressed to the inner surface of the sealing member 14, the coupling portion 13 is firmly coupled to the sealing member (14).

이렇게 결합부재(17)에 의해 결합부(13)가 실링부재(14)에 밀착 결합되면, 냉각홀(3)은 격판(11) 및 실링부재(14)에 의해 이분할되어 격판(11)을 중심으로 일측이 냉각수의 유입통로가 되고, 타측이 냉각수의 유출통로가 되며, 유입통로와 유출통로는 격판(11)의 상단부에 형성된 냉각수 통과홈(12)에 의해 연결된다.When the coupling part 13 is tightly coupled to the sealing member 14 by the coupling member 17, the cooling hole 3 is divided into two parts by the diaphragm 11 and the sealing member 14 to separate the diaphragm 11. One side is the inflow passage of the coolant as a center, the other side is the outflow passage of the coolant, and the inflow passage and the outflow passage are connected by the coolant passage groove 12 formed at the upper end of the diaphragm 11.

냉각홀(3)에 본 발명에 따른 사출금형의 냉각 칸막이(10)의 설치가 완료되면, 제품의 사출 성형을 시작하고, 상부금형(2)과 하부금형(1)의 형합을 통해 형성된 캐비티에 용융수지가 충진되면 금형을 냉각시키고, 용융수지의 신속한 응고를 유도하기 위해 냉각수를 공급한다.When the installation of the cooling partition 10 of the injection mold according to the present invention in the cooling hole 3 is completed, injection molding of the product is started, and the cavity formed through the combination of the upper mold 2 and the lower mold 1 is formed. When the molten resin is filled, the mold is cooled, and cooling water is supplied to induce rapid solidification of the molten resin.

금형의 내부로 공급된 냉각수는 공급라인을 통해 냉각홀(3)의 유입통로로 유입되고, 냉각수 통과홈(12)과, 냉각수 유출통로를 통과하는 과정에서 금형으로부터 열을 흡수한 뒤, 냉각수의 배출라인을 통해 배출된다. 냉각수의 순환과정을 통해 금형은 냉각되고, 용융수지 역시 신속하게 응고되어 제품의 생산 속도가 빨라진다.Cooling water supplied into the mold flows into the inflow passage of the cooling hole 3 through the supply line, absorbs heat from the mold in the process of passing through the cooling water passage groove 12 and the cooling water outlet passage, and then It is discharged through the discharge line. Through the circulation of the cooling water, the mold is cooled, and the molten resin is also solidified quickly to speed up the production of the product.

본 발명에 따른 사출금형의 냉각 칸막이는 사출성형이 이루어지는 사출금형의 냉각을 위한 냉각수의 유동경로를 형성하기가 용이하기 때문에 금형의 제작 단가를 낮출 수 있다.Cooling partition of the injection mold according to the present invention can reduce the manufacturing cost of the mold because it is easy to form a flow path of the cooling water for cooling the injection mold is made injection molding.
