Description

탠덤형 사출성형기의 잠금장치{A locking device for tandem type injection molding machine}[0001] The present invention relates to a locking device for a tandem type injection molding machine,

본 발명은 탠덤형 사출성형기의 잠금장치에 관한 것으로서, 더욱 상세하게는 고정금형과 중간금형 및 가동금형과 중간금형 각각을 걸림단 및 걸림고리라는 잠금수단을 매개하여 이들 상호간을 결합 및 해제하는 방식을 제안함으로써 작동과정에서 잠금수단의 파손을 최소한으로 할 수 있으며, 나아가 잠금수단의 교체작업을 매우 편리하게 수행할 수 있는 탠덤형 사출성형기의 잠금장치에 관한 것이다.The present invention relates to a locking device for a tandem type injection molding machine, and more particularly, to a locking device for a tandem type injection molding machine in which a fixed mold, an intermediate mold, a movable mold and an intermediate mold are respectively engaged and disengaged by a locking means, The present invention relates to a locking device for a tandem injection molding machine which can minimize the breakage of the locking means during the operation and can perform the replacing operation of the locking means very conveniently.

탠덤형 사출성형기는 삼단금형을 적용하여 2개의 면에서 성형품을 동시 생산을 하거나, 서로 다른 부품을 순차적으로 성형하는 성형기로서, 일반사출분야는 물론 디스플레이, 자동차, 백색가전 및 생활용기 등 다양한 분야에 널리 활용되고 있으며, 관련 시장의 규모가 지속적으로 빠르게 성장하고 있다.The tandem injection molding machine is a molding machine that uses a three-stage mold to simultaneously produce molded parts on two sides or sequentially form different parts. The tandem injection molding machine is used in various fields such as displays, automobiles, white goods, It is widely used, and the size of the related market is steadily growing rapidly.

종래 탠덤형 사출성형기의 개략적인 구성도가 도 2에 개시되어 있다. 탠덤형 사출성형기는, 고정판(14)과 가동판(12)을 상호 대향한 상태에서, 가동판(12)이 직선바(T)를 따라 고정판(14) 방향으로 왕복하면서 금형어셈블리(M1)를 이루는 가동금형(16), 중간금형(18), 고정금형(20) 상호간의 개폐동작을 수행한다. 이때, 고정판(14)에는 고정금형(20)이 고정되며, 가동판(12)에는 가동금형(16)이 고정된다.A schematic diagram of a conventional tandem injection molding machine is shown in Fig. The tandem injection molding machine is a molding machine in which the movable plate 12 reciprocates in the direction of the fixed plate 14 along the linear bar T while the fixed plate 14 and the movable plate 12 are opposed to each other, Closing operation between the movable mold 16, the intermediate mold 18, and the stationary mold 20 is performed. At this time, the stationary mold 20 is fixed to the stationary plate 14, and the movable mold 16 is fixed to the movable plate 12.

이러한 구성을 이용하여, 가동금형(16)과 중간금형(18)이 잠금장치(22/Compact Locking System, 또는 CLS)의 잠금수단(24)에 의해 잠금이 이루어지면, 중간금형(18)과 고정금형(20) 상호간은 형개상태가 된다. 이와 반대로, 고정금형(20)과 중간금형(18)이 잠금장치(22)의 잠금수단(24)에 의해 잠금이 이루어지면 중간금형(18)과 가동금형(16) 상호간은 형개상태가 된다. 이처럼, 가동금형 및 중간금형(16, 18)과 중간금형 및 고정금형(18, 20) 상호간에 형개와 형폐가 좌우로 번갈아 가며 이루지면서 사출성형을 하게 되는 것이다.When the movable mold 16 and the intermediate mold 18 are locked by the locking means 24 of the locking device 22 or the compact locking system 22 or CLS using this structure, The molds 20 are opened. Conversely, when the stationary mold 20 and the intermediate mold 18 are locked by the locking means 24 of the locking device 22, the intermediate mold 18 and the movable mold 16 are opened. As described above, the injection molding is carried out by alternately arranging the mold and the mold between the movable mold and the intermediate molds 16, 18 and the intermediate mold and the stationary molds 18, 20 alternately.

한편, 가동금형 및 중간금형과 중간금형 및 고정금형 상호간을 형폐하는 잠금장치는, 공압으로 작동하는 실린더와, 타단부위는 실린더에 결합되고 일단부위에는 걸림고리가 마련되어 중간금형의 홈에 삽입되는 작동핀으로 구성된다. 그런데,작동핀의 걸림고리가 중간금형의 홈에 정확하게 삽입되지 않은 상태에서 공압실린더가 작동하게 되면, 구조적으로 취약한 실린더와 작동핀 사이의 결합부위가 쉽게 파손된다. 이럴 경우, 잠금장치 자체를 교체해야 하기 때문에 교체비용이 상당하여 장치의 운영비를 증가시킴은 물론 사출성형작업 자체가 중단된다는 점에서 현저히 떨어지는 문제가 있었다.On the other hand, the locking device for closing the movable mold, the intermediate mold and the intermediate mold and the stationary mold includes a cylinder operated by pneumatic pressure and a cylinder having the other end coupled to the cylinder, And an operating pin. However, when the pneumatic cylinder is operated without the engagement ring of the operation pin being inserted into the groove of the intermediate mold correctly, the joint between the structurally weak cylinder and the operation pin is easily broken. In this case, since the locking device itself needs to be replaced, there is a problem that the replacement cost is considerable and the operation cost of the apparatus is increased, and the injection molding operation itself is stopped.

The movable mold clamping end 24 is provided with an insertion end protruding downwardly by a predetermined length and is provided on the movable mold 2 by being turned right and left with respect to the second intermediate mold clamping end 36. [

제2작동핀(26)의 일단부위는 제2공압실린더(22)와 결합되며, 타단부위에는 제2걸림고리(27)가 마련된다. 제2걸림고리(27)는 가동금형(2)과 중간금형(3)이 형폐될 때 제2중간금형걸림단(36)과 가동금형걸림단(24)을 동시에 가압하여 중간금형(3)을 가동금형(2)에 긴밀하게 구속한다. 제2걸림고리(27)의 형상은 전술한 제1걸림고리(17)와 대동소이하다.One end of the second actuating pin 26 is engaged with the second pneumatic cylinder 22 and the other end of the second actuating pin 26 is provided with a second retaining ring 27. The second latching ring 27 simultaneously presses the second intermediate mold engaging end 36 and the movable mold engaging end 24 when the movable mold 2 and the intermediate mold 3 are closed to press the intermediate mold 3 And is closely confined to the movable mold (2). The shape of the second latching ring 27 is similar to that of the first latching ring 17 described above.

이러한 구성으로 이루어지는 본 발명에 따른 잠금장치의 개략적인 작동구성은 아래와 같다.A schematic operation configuration of the lock device according to the present invention having such a configuration is as follows.

먼저, 제1, 2공압실린더(12, 22)이 일방향으로 작용하여 제1, 2작동핀(16, 26)이 전진하면, 제2걸림고리(17)는 고정금형걸림단(14)과 제1중간금형걸림단(32)을 동시에 가압하고, 제2걸림고리(27)는 가동금형걸림단(24)과 제2중간금형걸림단(36)을 동시에 가압한다. 이에 따라, 고정금형(1), 중간금형(3), 가동금형(2) 상호간은 긴밀하게 구속된다.When the first and second pneumatic cylinders 12 and 22 act in one direction to advance the first and second operation pins 16 and 26, the second retaining ring 17 is moved in the direction The intermediate mold clamping end 32 is simultaneously pressed and the second clamping ring 27 presses the movable mold clamping end 24 and the second intermediate mold clamping end 36 simultaneously. Accordingly, the stationary mold 1, the intermediate mold 3, and the movable mold 2 are tightly bound together.

다음으로, 제1공압실린더(12)이 타방향으로 작용하여 제1작동핀(16)이 후퇴하면, 제1중간금형걸림단(32)은 고정금형걸림단(14)과 분리되어 중간금형(2)과 고정금형(1)의 구속상태는 해제된다. 이때, 제2공압실린더(22)은 계속하여 일방향으로 작용하고 있기 때문에, 제어신호가 입력되면 중간금형(3)은 가동금형(2)과 일체화되어 고정금형(1)으로부터 분리되어 도면에서 좌측으로 일정거리 이동한다.Next, when the first pneumatic cylinder 12 acts in the other direction and the first actuating pin 16 is retracted, the first intermediate mold engaging end 32 is separated from the fixed mold engaging end 14, 2 and the fixed mold 1 are released. At this time, since the second pneumatic cylinder 22 continues to operate in one direction, when the control signal is inputted, the intermediate mold 3 is integrated with the movable mold 2, separated from the stationary mold 1, Moves a certain distance.

뒤이어 제어신호가 입력되어 제2공압실린더(22)가 타방향으로 작용하면 제2작동핀(26)이 후퇴하게 되고, 이에 따라 제2중간금형걸림단(36)은 가동금형걸림단(24)과 분리되어 중간금형(2)과 가동금형(3)의 구속상태는 해제된다. 이후, 입력되는 제어신호에 따라 가동금형(2)이 도면에서 좌측으로 일정거리 이동하면 가동금형(2)과 중간금형(3)은 완전히 분리되며, 이때 사출성형물의 취출이 이루어진다.
