하부 지지대(120)는 구동부(500)의 동작에 따라서 상하 방향으로 이동할 수 있으며, 이에 따라서 제2지지부(120)가 금형(100)으로부터 이격될 수도 있고, 또는 제2지지부(120)가 금형 하면에 밀착될 수 있다The lower support 120 may move in the vertical direction according to the operation of the driving unit 500 , and accordingly, the second support 120 may be spaced apart from the mold 100 , or the second support 120 may be can be attached to
제2지지부(120)가 금형(100) 하면에 밀착되면, 제2지지부(120)의 상부에 위치한 다수의 돌출부(130)가 금형(100) 내부의 프리폼 캐비티(C)에 삽입되어 프리폼을 성형할 수 있는 프리폼 성형 공간 환경을 제공한다. 이 상태에서 제1지지부(110)의 안내 유로(111)를 통해서 액상의 수지 재료가 유입되면 프리폼이 성형될 수 있다. When the second support part 120 is in close contact with the lower surface of the mold 100 , a plurality of protrusions 130 located on the upper part of the second support part 120 are inserted into the preform cavity C inside the mold 100 to mold the preform. It provides a preform molding space environment that can do this. In this state, when the liquid resin material flows through the guide passage 111 of the first support unit 110 , the preform may be molded.
본 발명에 따른 프리폼 성형 모듈(1)의 최하면에는 베이스판(610)이 마련되고, 베이스판(610)에 구동부(500)가 위치한다. 구동부(500)는 액츄에이터(510)와, 액츄에이터(510)에 연결되는 구동력 전달수단(예, 벨트 또는 체인 또는 기어(미도시))(520)과, 구동력 전달 수단(520)과 연결되는 회전수단(530)과, 회전 수단(530)의 회전운동을 직선운동으로 변환하는 직선운동 변환부(540)를 포함한다. A base plate 610 is provided on the lowermost surface of the preform molding module 1 according to the present invention, and the driving unit 500 is positioned on the base plate 610 . The driving unit 500 includes an actuator 510 , a driving force transmitting means (eg, a belt or chain or gear (not shown)) 520 connected to the actuator 510 , and a rotating means connected to the driving force transmitting means 520 . 530 and a linear motion converting unit 540 for converting the rotational motion of the rotating means 530 into a linear motion.
직선 운동 변환부(540)는 회전 수단(530)에 연결되어 회전 수단(530)의 회전에 따라 회전하는 수나사봉(541)과, 수나사봉(541)에 나사결합되고, 하부 지지대(220)에 연결되는 암나사블럭(542)을 포함한다. The linear motion conversion unit 540 is connected to the rotation means 530 and rotates according to the rotation of the rotation means 530 , and is screwed to the male screw rod 541 and the male screw rod 541 , and to the lower support 220 . It includes a female screw block 542 to be connected.
따라서, 액츄에이터(510)가 동작하면, 구동력 전달수단(520)이 회전수단(530)을 회전시키고, 회전 수단(530)의 회전에 따라서 수나사봉(541)이 회전하며, 이에 맞물린 암나사 블럭(542)이 상부 방향이나 하부방향으로 이동하고 이에 따라서 하부 지지대(220) 및 제2지지부(120)가 상부 방향이나 하부 방향으로 이동할 수 있다. Therefore, when the actuator 510 operates, the driving force transmitting means 520 rotates the rotating means 530 , and the male threaded rod 541 rotates according to the rotation of the rotating means 530 , and the female threaded block 542 engaged therewith. ) moves in an upper direction or a lower direction, and accordingly, the lower support 220 and the second support 120 may move in an upper direction or a lower direction.
상하 운동의 안정성과 균형을 위해서, 구동부(500)가 베이스부(610)의 앞과 뒤에 각각 배치되는 것이 바람직하나, 이에만 한정되는 것은 아니며, 그 수량의 배치방향은 다양하게 이루어질 수 있다.For stability and balance of the vertical movement, the driving unit 500 is preferably arranged in front and behind the base unit 610, respectively, but is not limited thereto, and the arrangement direction of the quantity may be made in various ways.
보조 가이드바(420)의 하단부와 중간 가이드 바(410)의 하단부는 모두 베이스부(610)에 확실하게 고정된다. Both the lower end of the auxiliary guide bar 420 and the lower end of the intermediate guide bar 410 are securely fixed to the base portion 610 .
한편, 중간 가이드바(410)의 중간 부분(또는 중간보다 위쪽 또는 아래쪽)의 외주면에는 상하 방향으로 형성되는 다수의 요철부(411)가 마련된다. 이 요철부(411)는 하부 지지대(220)의 아래에 있는 클램핑(700) 모듈의 동작에 의하여 클램핑 모듈(700)에 의하여 파지되거나, 파지 해제되는 부분이다.On the other hand, on the outer peripheral surface of the middle portion (or upper or lower than the middle) of the intermediate guide bar 410 is provided with a plurality of concavo-convex portions 411 formed in the vertical direction. The concave-convex portion 411 is a portion that is gripped or released by the clamping module 700 by the operation of the clamping module 700 under the lower support 220 .
하부 지지대(220)가 상승 이동하여, 돌출부(130)가 금형(100) 내부의 프리폼 캐비티(C)에 삽입되어 있는 상태에서, 그 위치가 유지되기 위해서는 하부 지지대(220) 및 제2지지대(120)가 하강이동을 하면 안된다.In a state in which the lower support 220 moves upward and the protrusion 130 is inserted into the preform cavity C inside the mold 100 , the lower support 220 and the second support 120 are maintained in order to maintain their position. ) should not move downward.
다만, 사출 장치에 의하여 공급되는 액상의 사출 재료의 공급 압력이 강한 경우, 그 압력에 의하여 금형(100)과 제2지지부(120) 간의 간격이 벌어져서, 프리폼 캐비티(C) 내부의 밀폐상태가 해제될 수 있다.However, when the supply pressure of the liquid injection material supplied by the injection device is strong, the gap between the mold 100 and the second support part 120 is widened by the pressure, and the sealed state inside the preform cavity (C) is released. can be
따라서, 이런 문제를 원천적으로 차단하기 위해서, 금형(100) 내부 프리폼 캐비티(C)에 돌출부(130)가 삽입되어 밀폐된 상태를 유지하기 위해서 하부 지지대 (220)아래에 마련되는 클램핑 모듈(700)이 중간 가이드바(410)의 요철부(411)를 파지하여 하부 지지대(220) 및 제2지지부(120)의 하강을 방지한다.Therefore, in order to fundamentally block this problem, the protrusion 130 is inserted into the preform cavity C inside the mold 100 and the clamping module 700 is provided under the lower support 220 to maintain the sealed state. The lower support 220 and the second support 120 are prevented from descending by gripping the concave-convex portion 411 of the intermediate guide bar 410 .
그리고, 금형(100)의 프리폼 캐비티(C) 내부에 수지 재료가 충만되어 프리폼을 형성할 시간이 완료되면, 클램핑 모듈(700)의 파지 상태가 해제되고, 이후 하부 지지대(220) 및 제2지지부(120)가 하강할 수 있다.And, when the resin material is filled in the preform cavity C of the mold 100 and the time to form the preform is completed, the holding state of the clamping module 700 is released, and then the lower support 220 and the second support part (120) can descend.
도시되지는 않았지만, 제2지지부(120)와 금형(100) 사이에는 립플레이트(미도시)가 배치되고, 돌출부(130)는 립플레이트를 관통하여 금형(100) 내부로 삽입된다. 그 상태에서 수지재료가 프리폼 캐비티(C) 내부로 유입되어 프리폼이 성형되면, 프리폼의 입구가 하향 배치된 상태에서 립 플레이트에 지지되는 상태가 된다.Although not shown, a lip plate (not shown) is disposed between the second support part 120 and the mold 100 , and the protrusion part 130 penetrates the lip plate and is inserted into the mold 100 . In this state, when the resin material flows into the preform cavity C and the preform is molded, the preform enters a state supported by the lip plate in a downwardly arranged state.
그리고 프리폼을 탑재한 립 플레이트는 블로윙 하기 위한 장치로 이동하여 용기가 성형될 수 있도록 한다. 립플레이트의 동작 및 지지 상태는 종래 기술에도 나타나 있으므로 구체적인 설명은 생략한다.And the lip plate on which the preform is mounted moves to the device for blowing so that the container can be molded. Since the operation and support state of the lip plate are also shown in the prior art, a detailed description thereof will be omitted.
도4 내지 도6은 구동부(500)에 의하여 하부 지지대(220) 및 제2지지부(120)가 상승하여, 돌출부(130)가 금형(100)의 프리폼 캐비티(C) 내부로 삽입되는 것을 도시한 것이다. 금형(100)과 제2지지부(120) 사이에는 빈 립플레이트가 위치하고, 각 립플레이트의 돌출된 지지부가 금형(100)의 프리폼 캐비티(C) 하부에 삽입된다.4 to 6 show that the lower support 220 and the second support 120 are raised by the driving unit 500, and the protrusion 130 is inserted into the preform cavity C of the mold 100. will be. An empty lip plate is positioned between the mold 100 and the second support part 120 , and the protruding support part of each lip plate is inserted into the lower part of the preform cavity C of the mold 100 .
이 상태에서 도5에서 박스로 표시한 부분과 같이, 중간 가이드바(410)의 외주면에 형성된 요철부(411)가 클램핑 모듈(700)의 일 구성요소인 홀더(710) 내면에 있는 대응 요철부(711c, 712c)와 맞물린다.In this state, as shown by the box in FIG. 5 , the concave-convex portion 411 formed on the outer circumferential surface of the intermediate guide bar 410 is the corresponding concave-convex portion on the inner surface of the holder 710 , which is a component of the clamping module 700 . (711c, 712c) engage.
클램핑모듈(700)은 하부 지지대(220)의 하부에 고정되어 있기 때문에, 요철부(411)와 대응 요철부(711c, 712c)가 맞물리면, 액상의 사출 재료가 프리폼 캐비티(C) 내부에 유입되어 하방으로 압력을 가하여도, 제2지지대(120)와 하부 지지대(220)가 하강하지 않는다. Since the clamping module 700 is fixed to the lower part of the lower support 220, when the uneven portion 411 and the corresponding uneven portions 711c and 712c are engaged, the liquid injection material flows into the preform cavity (C). Even when pressure is applied downward, the second support 120 and the lower support 220 do not descend.
클램핑모듈(700)에 관한 구조는 도7 내지 도11에 개시된다. The structure of the clamping module 700 is shown in FIGS. 7 to 11 .
클램핑 모듈(700)은 양 측에 마련되며 상기 중간 가이드바(410)의 외주면에 있는 요철부(411)를 파지하거나 파지 해제하는 홀더(710) 및 홀더(710)와 연결되어 홀더(710)의 파지 동작 또는 파지 해제 동작을 유발하는 클램핑 액츄에이터(720)를 포함한다. The clamping module 700 is provided on both sides and is connected to the holder 710 and the holder 710 for gripping or releasing the concave-convex portion 411 on the outer circumferential surface of the intermediate guide bar 410 . and a clamping actuator 720 for causing a gripping action or a gripping release action.

In addition, the link member 330 is arranged to be inclined, and pulls the horizontal moving member 340 inward.
이에 따라서, 수평 이동 부재(340)에 마련되는 관통공(341a)의 외측 내면과, 내측 내면은 중간 가이드바(340)와 이격되어 있고, 수평 이동부재(340)의 외측단부는 상부 지지대(210)의 측벽과 이격되어 있다.Accordingly, the outer inner surface and the inner inner surface of the through hole 341a provided in the horizontal moving member 340 are spaced apart from the intermediate guide bar 340 , and the outer end of the horizontal moving member 340 is the upper support 210 . ) is spaced apart from the sidewall.
이 상태에서는 도16(a)와 같이, 홀더(711,712)의 대응 요철부(711c(712c))와, 중간 가이드바(410)의 요철부(411)가 미세하게 상하 방향으로 이격되어 있다(G로 표시).In this state, as shown in Fig. 16(a), the corresponding uneven portions 711c (712c) of the holders 711 and 712 and the uneven portions 411 of the intermediate guide bar 410 are minutely spaced apart in the vertical direction (G). indicated by).
이 상태에서, 수지 재료가 금형 내부에 주입되기 직전에, 중간 가이드바(410)와 홀더(711, 712) 간의 결합력을 높여서 금형(100)과 립플레이트 간의 밀착력을 높이기 위해서 도13과 같이, 밀착용 액츄에이터(310)가 동작하여, 밀착용 액츄에이터(310)의 로드(310a) 및 이에 연결된 수직 이동블록(320)이 완전히 하강한다.In this state, just before the resin material is injected into the mold, as shown in FIG. 13, in order to increase the bonding force between the intermediate guide bar 410 and the holders 711 and 712 to increase the adhesion between the mold 100 and the lip plate, as shown in FIG.

이에 따라서, 안내부재(350)에 연결된 중간 가이드바(410)도 살짝 위로 올라간다. Accordingly, the intermediate guide bar 410 connected to the guide member 350 also rises slightly upward.
이 경우, 수평 이동 부재(340)의 외측 단부는 상부 지지대(210)의 측벽에 닿고, 수평 이동 부재(340)의 관통공(341a)의 내측 내면이 중간 가이드바(410)의 표면에 접촉하여, 더 이상의 이동을 제한한다. In this case, the outer end of the horizontal moving member 340 is in contact with the sidewall of the upper support 210, and the inner inner surface of the through hole 341a of the horizontal moving member 340 is in contact with the surface of the intermediate guide bar 410. , restrict further movement.
