Description
본 고안은 2단 작업 금형의 작업 스트로크 절환 장치에 관한 것이다.The present invention relates to a work stroke switching device of a two-stage work die.
종래 자동차의 실내 천정판, 도어판 등의 내장재는 주로 화학섬유지와 우드판재 등을 중첩하고 성형 금형에서 가열 가압하여 성형 한 다음, 트리밍 금형에서 트리밍 하여 소망의 내장재를 제조하는 것이었다. 이러한 자동차 내장재의 제조과정은 성형 금형과 트리밍 금형을 각각 제작해야 하고, 제조 공정도 분리되어 있어, 자동차 내장재의 생산효율이 낮고 제조 코스트가 높아진다.Conventionally, interior materials such as interior ceiling panels and door panels of automobiles are mainly superposed on chemical fiber paper and wood board materials, molded by heating and pressing in a molding die, and then trimming in a trimming mold to produce a desired interior material. The manufacturing process of such automotive interior materials must be produced a molding die and a trimming mold, and the manufacturing process is also separated, the production efficiency of the automotive interior materials is low and the manufacturing cost is high.
위와 같은 문제점을 개선하는 고안으로 대한민국 실용신안공보 공개번호 실1994-0015052호에 자동차의 화학섬유 내장재를 성형과 동시에 트리밍하는 금형이 개시되어 있다. 구체적으로 성형과 동시 트리밍 금형은 상금형 패드의 테두리에 밀착되게 절단구를 고정하고, 하금형의 패드 테두리에 스프링으로 탄지되는 받침대를 상기 절단구에 대응 설치함으로써, 1차 프레스압으로 재료를 성형 및 냉각 시킨 후 2차 프레스압으로 트리밍 함에 의해, 하금형에 설치된 성형소재의 성형과 트리밍을 동시에 처리하는 것이다.In order to improve the above problems, a mold for trimming and simultaneously molding a chemical fiber interior material of an automobile is disclosed in Korean Utility Model Publication No. 1994-0015052. Specifically, the molding mold simultaneously fixes the cutting tool so as to be in close contact with the edge of the upper mold pad and forms a spring-supported base corresponding to the cutting tool at the lower mold pad, thereby forming the material at the first press pressure. And cooling and trimming at a second press pressure to simultaneously process molding and trimming of the molding material installed in the lower die.
그러나 상기 성형과 동시 트리밍 금형은 한 벌의 금형으로 생산 효율을 높이는 성과를 거두고 있으나, 동시 작업으로 제조되는 제품의 품질이 저하되는 또 다른 문제점을 불러오는 것이었다. 자세히는 상기 성형과 동시 트리밍 금형은 성형단계와 트리밍 단계가 금형 내에서 스프링의 압력에 따라 연속적으로 이루어지고 있어, 두 작업의 간섭에 의해 성형 완성도가 감퇴되고 트리밍 위치 오차가 커지는 것이었다.However, the molding and the trimming mold at the same time is achieving a result of improving the production efficiency with a single mold, it was to bring another problem that the quality of the product produced by the simultaneous operation is reduced. In detail, the molding and the trimming mold simultaneously perform the molding step and the trimming step in accordance with the pressure of the spring in the mold, so that the molding completeness is reduced and the trimming position error is increased by the interference of the two operations.
본 고안은 상기와 같은 문제점을 개선하는 고안으로 한 벌의 금형에 의해 성형과 트리밍을 연속 처리하되 성형과 트리밍을 분리하여 실시함에 의해, 고효율의 생산성을 유지하면서 동시에 고품질의 자동차 내장재를 제조할 수 있게 하는 2단 작업 금형의 작업 스트로크 절환 장치를 제공하려는 것이다. 본 고안은 금형에 연동되고 에어기구에 의해 구동되는 2단 작업금형의 스트로크 절환 장치를 제공하려는 것이다.The present invention is designed to improve the above problems by continuously forming and trimming by a set of molds, but by separating the molding and trimming, it is possible to manufacture high-quality automotive interior materials while maintaining high productivity. It is to provide a work stroke switching device of a two-stage work die. The present invention aims to provide a stroke switching device of a two-stage work mold which is linked to a mold and driven by an air mechanism.

본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.
성형을 위해 주 제어부에서 상금형(10)을 상승시켜 하금형(20)을 개방 시킨다. 상승 종단점에서 하금형(20)의 패드위에 성형 재료를 삽입한다. 재료가 삽입되면 성형 단계를 진행한다. 성형단계는 먼저 성형스트로크(s1)가 설정되도록 이동블록(25)의 스페이서(27)를 이동시킨 다음 상금형(10)을 하강시켜 재료를 성형한다. 성형이 완료되면 트리밍 단계를 진행한다. 트리밍 단계는 상금형(10)을 조금 상승시킨 상태에서 트리밍스트로크(s2)이 설정되도록 이동블록(25)의 스페이서(27)를 이동시키고 상금형(10)을 하이트블록(23)에 닿기까지 하강시키는 것이다. 이로써 성형과 트리밍이 분리된 연속 성형과정을 완료한다.The upper mold 10 is raised from the main controller to open the lower mold 20 for molding. Insert the molding material onto the pad of the lower die 20 at the rising end point. Once the material has been inserted, proceed with the molding step. In the molding step, first, the spacer 27 of the moving block 25 is moved so that the molding stroke s1 is set, and then the upper mold 10 is lowered to mold the material. When the molding is completed, proceed with the trimming step. In the trimming step, the spacer 27 of the moving block 25 is moved to set the trimming stroke s2 while the upper mold 10 is slightly raised, and the upper mold 10 is lowered until it reaches the height block 23. It is to let. This completes the continuous molding process with separate molding and trimming.
상기 이동블록(25)을 성형스트로크(s1)와 트리밍스트로크(s2)로 절환하는 에어기구의 동작은 다음과 같다. 제어부(40)에서 제1신호가 주어지면 솔레노이브밸브(36)가 피스톤로드(24)를 전진시킨다. 이동블록(25)은 지축(26a)으로 좌면(21)에 설치되고, 에어실린더(32)는 힌지(33)로 지지폴(31)에 지지되고, 이동블록(25)의 구동아암(26)과 피스톤로드(34)는 힌지(35)로 접속되어있어, 상기 피스톤 로드(34)의 전진은 지축(24)에 지지된 이동블록(25)의 스페이서(27)를 구정블록(15)의 축선상에 이동시켜 성형스트로크(s1)가 설정되는 것이다. 제어부(40)에서 제2신호가 주어지면 솔레노이드밸브(36)가 피스톤로드(24)를 후진시킨다. 이 동작에서 지축(24)에 지지된 이동블록(25)은 스페이서(27)를 고정블록(15)의 축 밖으로 이동 시켜 이때 금형에는 트리밍스트로크(s2)가 설정 된다.The operation of the air mechanism for switching the moving block 25 to the forming stroke s1 and the trimming stroke s2 is as follows. When the first signal is given from the controller 40, the solenoid valve 36 advances the piston rod 24. The moving block 25 is installed on the seat surface 21 by the support shaft 26a, the air cylinder 32 is supported by the support pole 31 by the hinge 33, and the driving arm 26 of the moving block 25. And the piston rod 34 is connected to the hinge 35, the advance of the piston rod 34 is to move the spacer 27 of the movable block 25 supported on the support shaft 24 to the shaft of the spout block 15 The molding stroke s1 is set by moving on the line. When the second signal is received from the controller 40, the solenoid valve 36 reverses the piston rod 24. In this operation, the movable block 25 supported by the support shaft 24 moves the spacer 27 out of the axis of the fixed block 15 so that a trimming stroke s2 is set in the mold.
또한 상기 이동블록(25)은 협소한 좌면(21)상에서 상기 작업 스크로크 절환동작을 이루기 위해 스페이서(27)의 외단면을 지축(24)의 원호선상에 근접하도록 외단 절삭부(28)를 구비하고 있다.In addition, the movable block 25 is provided with an outer cutting portion 28 so that the outer end surface of the spacer 27 is close to the circular arc of the support shaft 24 to achieve the working stroke switching operation on the narrow seat surface 21. Doing.
