Description

작업성이 양호한 진공성형장치Vacuum forming device with good workability
본 발명은 진공성형장치에 관한 것으로서, 보다 상세하게는 액상의 원료수지를 진공상태에서 성형하기 위한 몰드를 진공탱크에 쉽게 삽입하고, 작업대에 영향을 받지 않고 진공탱크의 도어를 개방 또는 차단할 수 있는 진공성형장치에 관한 발명이다.The present invention relates to a vacuum molding apparatus, and more particularly, a mold for forming a liquid raw material resin in a vacuum state can be easily inserted into a vacuum tank, and the door of the vacuum tank can be opened or blocked without being influenced by a work table. The present invention relates to a vacuum molding apparatus.
일반적으로 플라스틱제품을 성형 가공하는 방법으로 액상의 열경화성수지를 열경화시키는 액상수지 사출 성형법(LIM : Liquid Injection Molding)이 사용되고 있다. 이는 용융된 액상의 원료수지를 고온의 금형에 주입하고 가열하여 경화시키는 것으로서, 특히, 경화되는 원료수지에 기포가 발생되는 것을 억제시키기 위해 진공탱크에 몰드를 넣고 입구를 차단하여 진공상태에서 성형을 하고, 다시 경화시키는 진공성형장치가 제공되고 있다.In general, liquid injection molding (LIM: Liquid Injection Molding) is used to thermoset a liquid thermosetting resin as a method of molding a plastic product. This is to inject the molten liquid raw material resin into a high-temperature mold and heat it to harden. In particular, in order to suppress the generation of bubbles in the hardened raw material resin, a mold is put in a vacuum tank and the inlet is blocked to form a mold in a vacuum state. And a vacuum molding apparatus for curing again is provided.
이러한 종래 진공성형장치는 도 1에 도시된 바와 같이, 원형으로 되는 진공탱크(10)가 구비되고, 진공탱크의 전면에는 진공탱크(10) 내부를 차단하기 위한 도어(20)가 힌지(21) 결합되어 있다. 진공탱크(10)의 바닥에는 수평으로 되는 바닥판(11)이 구비되고, 진공탱크(10)의 내부 측면에는 가열부(30)가구비된다.This conventional vacuum forming apparatus, as shown in Figure 1, is provided with a circular vacuum tank 10, the front of the vacuum tank, the door 20 for blocking the interior of the vacuum tank 10, the hinge 21 Are combined. The bottom of the vacuum tank 10 is provided with a bottom plate 11 to be horizontal, the heating side 30 is provided on the inner side of the vacuum tank (10).
그리고, 진공탱크(10)의 외측에는 바닥판(11)의 높이와 일치하는 작업대(L)가 설치되고, 작업대(L) 위에 올려진 하나 또는 복수개의 몰드(40)를 밀어 진공탱크(10) 내부의 바닥판(11) 위로 옮겨 위치시킨다. 몰드(40)가 삽입된 진공탱크(10)는 도어(20)가 힌지(21)를 축으로 차단된 후 진공상태에서 성형이 진행된다.And, on the outside of the vacuum tank 10, a work table L corresponding to the height of the bottom plate 11 is installed, and pushes one or a plurality of molds 40 mounted on the work table L to vacuum tank 10 Move it to the bottom plate 11 inside. In the vacuum tank 10 in which the mold 40 is inserted, molding is performed in a vacuum state after the door 20 is blocked by the hinge 21.
이때, 진공탱크(10)에 삽입되기 전 몰드(40)에는 별도의 액상 원료수지 주입장치(도면에는 도시되지 않음)를 이용하여 별도의 장소에서 액상 원료수지를 주입한 상태로 삽입된다.At this time, the mold 40 is inserted into the mold 40 in a state of injecting the liquid raw material resin in a separate place using a separate liquid raw material injection device (not shown in the drawing) before being inserted into the vacuum tank 10.
그리고, 진공탱크(10)에 삽입된 몰드(40)는 측면에 설치된 가열부(30)로부터 발생하는 열이 전달되어 몰드(40) 내부의 액상 원료수지가 경화되는 것이다.In addition, the mold 40 inserted into the vacuum tank 10 transfers heat generated from the heating part 30 installed on the side to cure the liquid raw material resin inside the mold 40.
그러나, 상기와 같은 종래 진공성형장치는 원형으로 이루어짐에 따라, 바닥판(11)의 높이가 진공탱크(10)의 저면보다 높게 설치되고, 마찬가지로 작업대(L)의 높이도 바닥판(11)의 높이와 일치시킴에 따라 진공탱크(10)의 저면보다 높게 설치가 된다. 따라서, 진공탱크(10)의 도어(20)를 개방 또는 차단 시 작업대(L)에 의해 방해를 받게 되어 도어(20)를 개방 또는 차단시에는 작업대(L)의 위치를 옮기고, 몰드(40)를 진공탱크(10)로 삽입하는 때에는 다시 작업대(L)를 설치하여야 하므로 매우 불편하였다.However, as the conventional vacuum forming apparatus as described above is made in a circular shape, the height of the bottom plate 11 is installed higher than the bottom surface of the vacuum tank 10, and similarly, the height of the work table L is also lower than that of the bottom plate 11. In accordance with the height is installed higher than the bottom of the vacuum tank (10). Therefore, when the door 20 of the vacuum tank 10 is opened or blocked, it is disturbed by the work table L. When the door 20 is opened or blocked, the position of the work table L is moved, and the mold 40 is moved. When it is inserted into the vacuum tank 10, it was very inconvenient to install the work table (L) again.
또한, 원형의 진공탱크(10) 내부에 몰드(40)가 차지하는 공간은 중앙 일부만 차지함에 따라 몰드(40)의 양측면 및 상부는 활용을 하지 못하면서도 진공탱크(10)의 크기만 크게 되고, 진공에 소요되는 시간도 낭비되는 등 비효율적인 단점이 있다.In addition, since the space occupied by the mold 40 in the circular vacuum tank 10 occupies only a central portion, both sides and the upper portion of the mold 40 are not utilized, but only the size of the vacuum tank 10 becomes large, and the vacuum is increased. There is an inefficient disadvantage, such as wasted time.
아울러, 진공성형 후에 진공탱크(10) 내에서 경화작업을 진행함에 따라 연속작업이 어렵고 작업능률이 저하되는 문제점이 있다.In addition, as the curing operation in the vacuum tank 10 after the vacuum molding, there is a problem that the continuous operation is difficult and the work efficiency is lowered.
본 발명은 종래와 같은 여러 문제점을 해결하고자 안출된 발명으로서, 특히, 설치된 작업대에 영향을 받지 않고 진공탱크의 도어를 개폐할 수 있도록 하는데 그 해결의 과제가 있다.The present invention has been made to solve the various problems as the prior art, in particular, there is a problem of solving the problem to be able to open and close the door of the vacuum tank without being affected by the installed work table.
또한, 본 발명은 진공형성장치의 진공탱크 내부 공간에 몰드가 삽입된 후 여유공간을 최소화하여 진공효율이 향상되도록 하는데 다른 해결의 과제가 있다.In addition, the present invention has another problem to improve the vacuum efficiency by minimizing the free space after the mold is inserted into the inner space of the vacuum tank of the vacuum forming apparatus.
또한, 본 발명은 몰드에 주입되는 액상 원료수지를 별도의 장소에서 주입하지 않고, 진공형성장치의 진공탱크 내에 삽입된 상태에서 주입이 가능하도록 하는데 다른 해결의 과제가 있다.In addition, the present invention has another problem to enable the injection in the state of being inserted into the vacuum tank of the vacuum forming apparatus without injecting the liquid raw material resin injected into the mold in a separate place.
또한, 본 발명은 몰드의 이동이 용이하도록 하는데 다른 해결의 과제가 있다.In addition, the present invention has another problem to facilitate the movement of the mold.
