본 발명은 합성수지재로 압출 성형되는 문짝의 중공부 내로 충전재를 충전시킬수 있도록하는 문짝 압출성형장치에 관한 것으로써, 더욱 구체적으로는 문짝의 압출성형과 동시에 중공부내로 충전재를 충전시킬수 있도록하는 합성수지 문짝 압출 성형장치에 관한 것이다.The present invention relates to a door extrusion molding apparatus for filling a filler into a hollow part of a door that is extruded with a synthetic resin material, and more particularly, to a synthetic resin door for filling a filler into a hollow part at the same time as extrusion of the door. An extrusion molding apparatus.

일반적으로 합성수지재 문짝은 내부의 중공부로 인한 공명현상등으로 문의 개폐시 울림현성이 발생하고 문이 가벼움으로 인해 문짝의 중후감이 결여되어 중공부 내로 우레탄등과 같은 충전재를 충전사용하는 기술이 보편화 되어 있는 것이다.In general, synthetic resin doors have resonant phenomena due to internal hollow parts, which causes ringing to occur when opening or closing doors, and the lightness of the doors lacks the heavy feeling of the doors. It is.

종래 합성수지재 문짝의 중공부 내로 충전물을 충전하기 위하여는 합성수지 문짝을 성형시키는 압출 성형 공정과, 성형완료된 문짝의 중공부내에 충전재를 충전시키는 충전공정을 별도로 이행하게 되는 것으로, 상기 압출성형 공정은 도면 제1도 내지 제3도에 도시하는 바와같이 압출기(1) 내로 원료를 투입하면 압출기는 일정한 열과 압력으로 원료를 용융가압하여 금형부(10)쪽으로 밀어내고 금형부(10)를 통과하는 원료는 제1금형(11)과 제2금형(12)의 공간(14)내에 설치된 코어(15)에 의해 중공부(101) 및 보강리브(102)를 가지는 문짝(100)을 형성시키게 된다.In order to fill the filler into the hollow part of the conventional synthetic resin door, the extrusion molding process for molding the synthetic resin door and the filling step for filling the filler in the hollow part of the molded door are carried out separately. As shown in FIGS. 1 to 3, when the raw material is introduced into the extruder 1, the extruder melt-pressurizes the raw material at a constant heat and pressure to push the raw material toward the mold part 10, and the raw material passing through the mold part 10 is The core 100 provided in the space 14 of the first mold 11 and the second mold 12 forms the door 100 having the hollow portion 101 and the reinforcing rib 102.

이때 금형부(10)를 통과한 제품은 상당한 열을 보유하고 있기 때문에 대기와 접촉하면서 자체가 수축하게 되는데, 이를 방지하기 위하여 냉각조(2)에서 진공상태를 유지하며 냉각수로 제품이 보유한 열을 제거하여 성형시킨다. 이러한 성형된 제품은 일정한 속도로 회전하는 인취기(3)를 거치며 제품의 일정한 형성을 유지하고 커터(4)와 반전기(5)를 거쳐 제품의 압출 성형 공정을 완료한다.At this time, the product passed through the mold part 10 has a considerable heat, so that it contracts itself while in contact with the atmosphere. In order to prevent this, a vacuum state is maintained in the cooling tank 2 and the heat retained by the product with the cooling water is prevented. Remove and mold. This molded product is passed through a take-off (3) that rotates at a constant speed to maintain a constant formation of the product and complete the extrusion process of the product via the cutter (4) and the inverter (5).

이렇게 성형완료된 문짝(100)의 중공부(101) 내로 충전기를 이용하여 우레탄등과 같은 충전재를 충전시킨 다음 충전재의 발포시 발생되는 열에 의해 문짝이 변형되는 것을 방지하게 위해 별도의 프레스공정(도시생략)과 냉각공정(도시생략)을 거쳐 충전공정이 완료된다.Filling the filler such as urethane into the hollow portion 101 of the molded door 100 is formed in this way, and then a separate press process (not shown) to prevent the door from being deformed by the heat generated when the filler is foamed. ) And the cooling process (not shown) is completed.

이와같이 종래에는 문짝의 압출 성형 공정과 중공부내로의 충전공정이 별도의 생산 라인에서 이루어짐에 따라 별도의 작업공간과 사용설비가 거대해지며 이에 따른 인건비와 고정비 또한 과다하게 지출되는 문제점과 아울러 생산성 또한 저하되는 문제점이 있는 것이다.As described above, the extrusion process of the door and the filling process into the hollow part are performed in separate production lines, and thus a separate work space and equipment are enormous, resulting in excessive labor and fixed costs, as well as a decrease in productivity. There is a problem.

따라서 본 발명은 상기한 문제점을 해결하기 위한 것으로써, 본 발명의 목적은 문짝의 압출 성형 라인에서 중공부내로의 충전작업을 동시에 행할수 있도록 함으로써, 제품의 생산원가 절감과 제품의 생산성을 대폭 향상시킬 수 있도록 하는 문짝 압출 성형장치를 제공함에 있다.Therefore, the present invention is to solve the above problems, an object of the present invention is to perform the filling operation into the hollow part at the extrusion molding line of the door at the same time, significantly reducing the production cost of the product and product productivity significantly The present invention provides a door extrusion molding apparatus that can be used.

상기 목적을 달성하기 위한 본고안은 압출되는 원료가 통과되며 문짝을 형성시키는 금형부에 있어서, 상기 금형부 일측으로 다수의 충전노즐을 구비하는 충전금형을 설치하여 문짝의 압출성형과 동시에 중공부내의 충전재를 충전시킬수 있도록 한것에 특징을 둔 것이다.In order to achieve the above object, the present invention provides a mold for forming a door through which raw material to be extruded passes and forms a door, and at one side of the mold part, a filling mold including a plurality of filling nozzles is installed to simultaneously extrude the door and the inside of the hollow part. It is characterized by being able to charge the filling material.

이하 본 발명에 따른 문짝 압출 성형장치를 첨부된 도면에 의거하여 보다 상세하게 설명한다.Hereinafter, the door extrusion molding apparatus according to the present invention will be described in more detail with reference to the accompanying drawings.

도면 제4도 내지 제7도에 도시하는 바와같이, 압출되는 원료가 통과되며 문짝(100)을 형성시키는 제1금형(11)과 제2금형(12)의 공간(14) 내부에 성형되는 문짝(100)에 중공부(101)와 보강리브(102)를 형성토록 하는 코어(15)가 스페이서(13)에 의해 지지설치되는 금형부(10)에 있어서, 상기 제2금형(12)의 한쪽으로 공간부(21)의 하부면(22)에 충전기(30)와 연결되는 다수의 충전노즐(31)이 관통되게 설치된 충전금형(20)을 설치하며, 상기 충전노즐(31)의 돌출높이(T)는 코어(15)를 통과하여 형성되는 문짝(100)의 하부면벽체(103) 두께(t)보다 높게 형성함이 바람직하다.As shown in FIGS. 4 to 7, a door is formed in the space 14 of the first mold 11 and the second mold 12 through which the raw material to be extruded passes and forms the door 100. In the mold part 10 in which the core 15 for forming the hollow part 101 and the reinforcement rib 102 in the 100 is supported by the spacer 13, one side of the said 2nd mold 12 is carried out. In the lower surface 22 of the space portion 21 is installed a charging mold 20 is installed so that the plurality of charging nozzles 31 connected to the charger 30, the height of the protruding height (31) T is preferably formed higher than the thickness t of the lower surface wall 103 of the door 100 formed through the core 15.

그리고 상기 충전노즐(31)의 전후면, 즉 성형된 문짝(100)의 중공부(101) 하부면벽체(103)가 부딪혀 갈라지는 전면(a)와 갈라진 부분이 노즐(31)을 통과하여 재접합되는 후면(b)이 예리한 각도를 이루게 함으로써, 제품의 흐림을 원할하게 하며 노즐(31)에 의해 갈라진 부분이 신속하게 재접합되게 한다.In addition, the front and rear surfaces of the filling nozzle 31, that is, the front surface a and the split portion where the hollow part 101, the lower surface wall 103 of the molded door 100 collide with each other, pass through the nozzle 31 to be re-bonded. By making the rear side (b) at a sharp angle, the blurring of the product is desired and the portion cracked by the nozzle 31 is quickly rejoined.

이와같이 구성되는 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

먼저 압출기(1)로 투입된 합성수지 원료가 일정한 열과 압력으로 금형부(10)쪽으로 이송되어 제1금형(11)과 제2금형(12)의 공간(14)에 설치된 코어(15)에 의해 문짝(100)의 중공부(101)와 보강리브(102)가 형성되는 공정은 종래와 동일하게 진행된다.First, the synthetic resin raw material introduced into the extruder 1 is transferred to the mold part 10 at a constant heat and pressure, and the door is opened by the core 15 installed in the space 14 of the first mold 11 and the second mold 12. The process of forming the hollow portion 101 and the reinforcing rib 102 of 100 is performed in the same manner as in the prior art.

이와같이 문짝(100)의 형상을 이루며 제2금형(12)을 통과하는 문짝(100)은 충전금형(20)으로 유입되면서 문짝(100)의 중공부(101) 위치에 설치된 노즐(31) 전면부에 문짝(100)의 하부면 벽체(103)가 부딪치면서 갈라지게 되어 결과적으로는 다수의 충전노즐(31)이 문짝(100)에 형성된 각 중공부(101)에 관통된 상태를 이루게 되는 것이다.As described above, the door 100 passing through the second mold 12 forming the shape of the door 100 is introduced into the filling mold 20 and the front surface of the nozzle 31 installed at the hollow portion 101 of the door 100. The lower surface wall 103 of the door 100 hits and splits, resulting in a plurality of filling nozzles 31 penetrating through the hollows 101 formed in the door 100.

이때 상기 문짝(100)은 압출기(1)에 의해 겔 상태로 용융되어 충전노즐(31)과 접촉되면 별 무리 없어 갈라지게 된다. 또한 충전노즐(31)의 전면(a)이 예리한 각도로 형성되어 문짝(100)이 형성되어 진행하는 동작에 별다른 장애를 전가하지 않게 되고, 노즐(31)의 돌출높이(T)가 벽체(103)의 두께(t)보다 높게 되어 문짝의 중공부(101) 내로 노즐(31)이 관통된 상태를 이루게 된다.In this case, the door 100 is melted in a gel state by the extruder 1 and comes into contact with the filling nozzle 31 so that the door 100 is easily separated. In addition, the front surface (a) of the filling nozzle 31 is formed at a sharp angle so that the door 100 is formed so as not to impart any obstacle to the operation that proceeds, and the protrusion height T of the nozzle 31 is the wall 103 It becomes higher than the thickness (t) of the) to achieve a state in which the nozzle 31 penetrates into the hollow portion 101 of the door.

이와같이 충전노즐(31)이 문짝(100)의 각 중공부(101) 내로 관통되면 충전기(30)로부터 실리콘등과 같은 발포성 충전재가 토출되어 중공부(101) 내로 충전시키면서 진행되고 벽체(103)의 갈라진 부분은 충전노즐(31)을 통과하는 시점부터 충전금형(20)을 통과 진행되는 동안 재접합되어 벽체(103)의 표면에는 아무런 크랙이 발생하지 않는다. 또한 문짝이 완전히 응고되지 않고 노즐의 후면부가 예각으로 형성되어 갈라진 부분이 재접합되도록 유도함으로써, 별무리 없이 재접합이 이루어지는 것이다.As such, when the filling nozzle 31 penetrates into each hollow portion 101 of the door 100, a foamable filler such as silicon is discharged from the charger 30 to be filled into the hollow portion 101 and the wall 103 is filled with the filling nozzle 31. The cracked portion is re-bonded while passing through the filling mold 20 from the time when the filling nozzle 31 passes, so that no crack occurs on the surface of the wall 103. In addition, the door is not completely solidified, and the rear part of the nozzle is formed at an acute angle to induce the cracked portion to be rejoined, thereby rejoining without any problem.

이어 충전금형(20)을 완전히 통과한 문짝(100)은 종래와 동일하게 냉각조(2)에서 냉각되고 일정한 속도로 회전되는 인취기(3)를 거치며 제품의 일정한 형상을 유지하고 커터(4)에 의해 제품의 규격으로 절단되어 압출 성형 공정과 충전공정이 생산라인에서 모두 완료되는 것이다.Subsequently, the door 100 which has completely passed through the filling mold 20 passes through the take-out machine 3 which is cooled in the cooling tank 2 and rotated at a constant speed in the same manner as the conventional art, and maintains a constant shape of the product and the cutter 4. It is cut to the specifications of the product by the extrusion process and the filling process is completed in the production line.

이상에서와 같이 본 발명에 따른 문짝 압출 성형장치에 의하면 문짝(100)의 성형공정과 중공부(101) 내로의 충전공정을 하나의 생산라인에서 모두 이루어지므로서, 간단한 설비투자로 작업이 가능하고 별도의 충전작업 공간이 필요없고 적은 인원으로도 생산성을 대폭 향상시킬 수 있는 효과가 있는 것이다.As described above, according to the door extrusion molding apparatus according to the present invention, since the molding process of the door 100 and the filling process into the hollow part 101 are all made in one production line, work can be performed by simple equipment investment. There is no need for a separate filling work space and the productivity can be greatly improved even with a small number of people.
