Description
주지된 바와 같이, 플라스틱의 성형가공법의 하나인 사출성형은 열가소성 플라스틱을 성형하는 방법의 중심을 이루고 있는데, 그 공정을 간략하게 설명하면, 플라스틱에 안료·안정제·가소제·충전제 등이 첨가되어진 수 mm정도의 컴파운드(성형재료)를 호퍼에 넣게 되면 투입구측에 위치된 가열실로 유입되어 용융되어지는 바, 이것을 피스톤을 매개로 투입구를 통해 2개의 금형이 탈착되도록 된 사출금형에 사출하고, 사출금형을 냉각하여 2개의 금형을 분리한 후, 사출금형 내에서 굳어진 성형품을 끄집어 내는 것으로 이루어져 있다.As is well known, injection molding, which is one of the molding processing methods of plastics, forms the center of a method of molding thermoplastics. When the compound (molding material) of the degree is put into the hopper, it is introduced into the heating chamber located at the inlet side and melted. This is injected into the injection mold through which the two molds are detached through the inlet port via a piston. After cooling to separate the two molds, it is made to take out the molded product in the injection mold.
상기 사출성형은 매우 작은 것부터 무게 10kg에 이르는 큰 것까지 단번에 성형할 수가 있으며, 반복해서 사출하여 대량생산을 할 수 있으므로 작업능률이 높은 장점이 있다.The injection molding can be molded at once from a very small to a large one up to a weight of 10kg, it can be repeatedly injected and mass production has the advantage of high work efficiency.
한편,사출성형에 이용되는 사출금형은 투입구측에 고정된 고정측 금형과, 이 고정측 금형에 탈착되는 가동측 금형으로 구분되어 있는데, 사출성형에 있어서 이 사출금형의 냉각에 소요되는 공정시간은 사출성형의 전체 공정시간에 상당한 부분을 차지하고 있다.On the other hand, the injection mold used for injection molding is divided into a fixed side mold fixed to the inlet side and a movable side mold detachable to the fixed side mold. In injection molding, the process time required for cooling the injection mold is It is a significant part of the overall process time of injection molding.
이에 생산성을 향상시키기 위하여 사출금형의 냉각성능 및 효율이 향상되도록 하여 공정시간을 단축시키는 방안이 다방면으로 연구되고 있는데, 종래 사출금형의 냉각구조는 도3과, 도4에 도시되어 있는바, 도3은 종래 기술에 따른 냉각구조를 갖춘 사출금형의 정면도이고, 도4는 도3의 II - II측에서 바라본 상태도로서, 이에 의거하여 종래 사출금형의 냉각구조를 설명한다.In order to improve productivity, a method of shortening the process time by improving the cooling performance and the efficiency of the injection mold has been studied in various aspects. The cooling structure of the conventional injection mold is illustrated in FIGS. 3 is a front view of an injection mold having a cooling structure according to the prior art, and FIG. 4 is a state view seen from the II-II side of FIG. 3, and will explain a cooling structure of a conventional injection mold based on this.
도3과 도4에 따르면, 고정측 금형(12)과 가동측 금형(13)으로 구분되어진 사출금형(11)이 고정판(14, 15)에 각각 고정되어 있으며, 각각의 고정측 금형(12)과 가동측 금형(13)의 일측에는 냉각수 주입구(12a, 13a)와 배출구(12b, 13b)가 형성되어 직렬형태로 연통되게 연결되어 있다.3 and 4, the injection mold 11 divided into the stationary side mold 12 and the movable side mold 13 is fixed to the stationary plates 14 and 15, respectively. Cooling water inlets 12a and 13a and outlets 12b and 13b are formed at one side of the movable side mold 13 and connected in series.
따라서, 용융된 컴파운드가 피스톤을 매개로 사출금형(11)에 사출되면 상기 주입구(12a, 13a)로 냉각수가 유입되어 고정측 금형(12)과 가동측 금형(13)을 냉각시킨 후 배출구(12b, 13b)로 유출되어진다.Therefore, when the molten compound is injected into the injection mold 11 through the piston, the coolant flows into the injection holes 12a and 13a to cool the fixed side mold 12 and the movable side mold 13, and then discharge outlet 12b. 13b).
그러나, 상기 종래 기술에 의한 냉각구조는 직렬형태로 고정측 금형(12)과 가동측 금형(13)을 냉각하는 방식으로 되어, 냉각수가 주입구(12a, 13a)로 유입되어 배출구(12b, 13b)로 배출되는데 많은 시간이 소요되고, 이에 따라 냉각수가 냉각라인을 따라 이동되는 동안 고온상태로 되어 냉각기능이 저하되는 문제가 있다.However, the cooling structure according to the prior art is a system in which the fixed mold 12 and the movable mold 13 are cooled in series, so that the coolant flows into the inlets 12a and 13a to discharge the outlets 12b and 13b. It takes a long time to be discharged to, so there is a problem that the cooling function is deteriorated due to the high temperature while the coolant is moved along the cooling line.
이에 본 발명은 상기와 같은 문제점을 해소하기 위하여 발명된 것으로, 냉각수의 공급이 병렬형태로 이루어지도록 하여 종래 사출성형시에 발생되는 제반 문제를 해소함으로써 냉각이 균일하게 이루어지고, 냉각 성능 및 효율이 향상되도록 하는 사출금형의 냉각구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, the cooling water is made in parallel form to solve the problems caused in the conventional injection molding, cooling is made uniform, cooling performance and efficiency is improved It is an object of the present invention to provide a cooling structure of an injection mold to be improved.
