본 고안은 플라스틱 사출 성형용 금형의 냉각수 누수방지 장치에 관한 것으로서 특히 냉각수 통로를 드릴링 한 후 그 개구부를 세트볼트로 밀폐시킴에 있어서 그 결합부위가 냉각수로부터 완전히 차단되도록 개구부와 세트볼트를 개량시킨 고안이다.The present invention relates to a coolant leak prevention device of a plastic injection molding mold. In particular, an opening and a set bolt are improved so that the coupling part is completely blocked from the coolant when the cooling water passage is drilled and the opening is closed with a set bolt. to be.

잘알려진 바와 같이 사출금형은 제품 성형부에 고온의 수지가 사출되고 냉각후 고화된 상태로 제품을 취출하는 것으로서 냉각을 위하여는 금형의 다수의 홈(cavity)을 서로 교차시켜 드릴링 하여 냉각수 순환로를 만들고 그 드릴링 홈끝의 개구부는 밀봉하여 주되 냉각수가 누수되지 않도록 잘 밀봉해 주어야 한다.As is well known, injection mold is a product in which a high-temperature resin is injected into a product molding part, and the product is taken out in a solidified state after cooling. Openings at the ends of the drilling grooves are to be sealed but well sealed to prevent leakage of cooling water.

이를 위해 종래에는 제3도와 같이, 드릴링한 홈(3)의 한쪽 개구부(6)에 암나사(8)를 내고 이에 단순한 세트볼트(9)를 결합시켰었으나 이는 그 나사결합부위에 냉각수가 스며들어 부식되므로 조금씩 누수됨과 아울러 금형이 부분적으로 손상되는 문제점이 있었던 것이다.To this end, conventionally, as shown in FIG. 3, the female screw 8 is inserted into one opening 6 of the drilled groove 3, and a simple set bolt 9 is coupled thereto. As a result, there was a problem of leaking little by little and partially damaged the mold.

다른 한편으로는 세트 볼트를 사용하지 않고 동봉을 깎아 끼우되 코우팅하여 주기도 하였었으나 이 역시 장시간 경과하면 코우킹재가 노화하여 누수가 발생하게 되고 또한 분해가 불가능하므로 냉각수 순환로의 청소가 용이하지 못한 단점이 있는 것이다.On the other hand, the copper rods were cut and coated without using set bolts, but the coating was cycled.However, if a long time passes, the caulking material ages and leaks. Is there.

본 고안은 이러한 문제점을 감안하여 고안한 것으로서 분해결합이 가능하여 청소가 용이한 세트볼트방식을 채택하되 금형의 드릴홈 개구부에 단차를 형성하고 세트볼트에는 팩킹링을 결합시켜 나사결합부위가 냉각수로부터 완전차단 되게 함으로써 냉각수 누수는 물론 부식되는 문제점을 해소하려는 것인바 이를 첨부된 관련도면에 따라 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above problems and adopts a set bolt method that is easy to be disassembled and easy to clean, but forms a step in the opening of the drill groove of the mold and couples the packing ring to the set bolt. It is intended to solve the problem of cooling water leakage as well as corrosion by being completely blocked, which will be described in detail according to the accompanying drawings.

도시된 바와 같이, 통상의 제품성형부(2)를 갖는 금형(1)에 수개의 드릴링 홈(3)을 서로 교차되게 드릴링하여 냉각수 유입구(4) 및 유출구(5)와 함께 냉각수 순환로를 형성한 것에 있어서, 각기 홈(3)의 한쪽 개구부(6)에 단차면(7)을 두고 암나사(8)를 형성하는 한편, 이에 나사결합되는 세트볼트(9) 단면(10)에는 환형홈(11)을 내어 고무링(12)을 끼워주어 상기 단차면(7)에서 팩킹 되어지게끔 구성된 것이다.As shown, several drilling grooves 3 are drilled in a mold 1 having a conventional product forming part 2 to cross each other to form a cooling water circulation path together with the cooling water inlet 4 and the outlet 5. In each of the grooves 3, each of the grooves (3) having a stepped surface (7) to form a female screw (8), while the set bolt (9) screwed to the cross section 10 of the annular groove (11) It is configured to be packed in the step surface 7 by inserting the rubber ring 12.

이와 같은 본 고안 장치는 암나사(8)를 갖는 개구부(6)에 세트볼트(9)가 종전과 같이 나사 결합되면서 그 조임력에 의해 세트볼트(9)의 단면(10)과, 금형(1)의 드릴링홈(3)과 개구부(6)와의 단차면(7)사이에서 고무링(12)이 밀착되어지므로 냉각수 순환로를 흐르는 냉각수는 완전 차단된다.The device of the present invention as described above has the set bolt 9 screwed into the opening 6 having the female screw 8 as before, and the end face 10 of the set bolt 9 and the mold 1 by the fastening force thereof. Since the rubber ring 12 is in close contact between the drilling groove 3 and the step surface 7 between the opening 6, the cooling water flowing through the cooling water circulation path is completely blocked.

따라서 개구부(6)에 결합된 세트볼트(9)의 나사부위로는 냉각수가 전혀 침입할수 없으므로 완전 누수방지와 아울러 부식될 염려가 없는 것이다.Therefore, since the cooling water cannot penetrate at all into the screw portion of the set bolt 9 coupled to the opening 6, there is no possibility of corrosion and complete corrosion.

즉, 본 고안 장치에 의하면 냉각수 누수 방지는 물론, 그 부위의 부식을 미연에 방지하여 주므로 금형의 적정 수명을 유지시켜 주는 효과가 있다.That is, the device of the present invention not only prevents cooling water leakage, but also prevents corrosion of the part in advance, thereby maintaining the proper life of the mold.
