Description

차량용 내장재 제조장치{Car interior material manufacuring apparatus }{Car interior material manufacuring apparatus}

본 발명은 차량용 내장재 제조장치에 관한 것이다. 보다 상세하게는 제1 부재에 제2 부재를 사출하여 부품의 테두리에 플랜지 구조를 형성할 때 발생되는 플랜지 골주름을 방지하도록 하는 차량용 내장재 제조장치에 관한 것이다. The present invention relates to a vehicle interior material manufacturing apparatus. And more particularly, to an automotive interior material manufacturing apparatus for preventing a wrinkle of a flange which is generated when a second member is injected into a first member to form a flange structure on a rim of a part.

일반적으로, 차량용 내장재는 차량의 내부 인테리어에 사용되는 부품으로서, 종래 차량용 내장재의 제조방법은, 원단과 기재를 별도로 성형한 다음 접착하거나, 도 1에 도시된 바와 같이 일체성형방법을 사용한다.In general, a vehicle interior material is a component used for interior decoration of a vehicle. In a conventional method for manufacturing an interior material for a vehicle, a raw material and a base material are separately molded and then bonded or an integral molding method is used as shown in Fig.

이와 같은 일체성형방법은 공정을 축소하고 접착제로 인한 휘발성 유기 화합물(volatile organic compound, VOC)를 줄이고자 개선된 방법으로써, 도 1을 참조하여 보다 자세히 설명한다.Such an integral molding method is an improved method for reducing a process and reducing a volatile organic compound (VOC) due to an adhesive, which will be described in detail with reference to FIG.

먼저, 원단(20)을 예열한 다음, 제1 금형(11)에 엠보형상 및 진공홀을 가공하여 가열된 원단을 인서트한다.First, after the fabric 20 is preheated, the embossed shape and the vacuum hole are formed in the first mold 11 to insert the heated fabric.

이후, 제2 금형(13)에 형성된 사출구(14)를 통해 사출금형 내로 기재(30)를 저압으로 사출한다.Thereafter, the base material 30 is injected into the injection mold through the injection port 14 formed in the second mold 13 at a low pressure.

기재(30)의 저압 사출시에 원단(20)의 성형 및 표면 엠보를 구현하기 위해서 제1 금형(11)에서 진공성형을 진행하고, 제1 및 제2 금형(11,13)이 압축되면서 원단(20)과 기재(30)가 일체성형되어 내장재 부품이 제조된다.Vacuum molding is carried out in the first mold 11 in order to realize the molding of the fabric 20 and the surface emboss in the release of the low pressure yarn of the substrate 30 and the first and second molds 11 and 13 are compressed, (20) and the base material (30) are integrally formed to manufacture an interior part.

제조된 내장재 부품은 연결되는 상대 부품과의 결합을 위해 테두리 또는 양끝단에 플랜지 구조가 구비될 수 있다. The manufactured interior part may be provided with a flange or a flange structure at both ends in order to engage with a mating part to be connected.

도 2 및 도 3은 차량용 내장재 부품의 플랜지를 도시한 것으로, 도 2 및 도 3을 참조하면, 플랜지가 시작되는 꺾임부(20a)에는 골주름이 발생한 것을 알 수 있다. 즉, 플랜지 꺾임부(20a)에서는 원단(20)이 꺾이면서 원단 폼으로 형성된 기재(30)가 과다하게 압착되는데, 꺾임부(20a)의 주변의 폼 압착량과의 편차가 발생되기 때문에 원단(20) 표면에 외관상 골주름이 발생되었다. 2 and 3 show flanges of the automotive interior parts. Referring to FIGS. 2 and 3, it can be seen that the folds 20a at which the flanges start are corrugated. That is, in the flange bending portion 20a, the base material 30 formed of a raw foil is excessively pressed while the raw material 20 is being bent. Since the deviation from the amount of the foam pressed around the bending portion 20a occurs, 20) appearance of wrinkles on the surface.

도어트림과 같이 플랜지가 노출되는 부품인 경우, 상기 플랜지 골주름에 의한 외관 불량 처리로 인한 비용 손실 부담이 커지는 문제점이 있었다.There is a problem in that, in the case of a component in which a flange is exposed as in a door trim, a cost burden is increased due to an appearance defect treatment due to the flange tread.

다음으로, 형개된 제1 금형(111) 및 제2 금형(113) 내로 예열된 제1 부재(120)를 인서트하여 제1 금형(111)에 고정시킨다(b). Next, the first member 120 preheated into the first mold 111 and the second mold 113 is inserted and fixed to the first mold 111 (b).

이때, 제2 금형(113)에 설치된 감압코어(140)는 유압실린더(143)에 의해 가압되어 상측으로 전진되어 제2 금형(113)의 성형면이 연속된 상태를 유지하도록 한다.At this time, the decompression core 140 installed in the second mold 113 is pressed by the hydraulic cylinder 143 and advanced to the upper side so that the molding surface of the second mold 113 is maintained in a continuous state.

이후, 제1 금형(111)에 구비된 진공홀(112)을 통해 예열된 제1 부재(120)와 제1 금형(111)사이의 공기를 흡기한다(c).Thereafter, the air between the first member 120 preheated through the vacuum hole 112 provided in the first metal mold 111 and the first metal mold 111 is drawn in (c).

공기가 흡기되면, 원단소재인 제1 부재(120)가 제1 금형(111)에 밀착되고, 예열된 제1 부재(120)는 프리포밍(Pre-foaming)되고, 표면이 엠보전사된다(d).When air is sucked in, the first member 120 as a raw material is brought into close contact with the first mold 111, the preheated first member 120 is pre-foaming, and the surface is embossed (d ).

이때, 제1 부재(120)는 일측에는 꺾임부(120a)가 형성되고, 타측에는 절곡부(120b)가 형성된다.At this time, the first member 120 is formed with a bent portion 120a at one side and the bent portion 120b is formed at the other side.

이후, 제2 금형(113)이 상측으로 전진하여 성형공간을 형성한 다음, 제2 부재(130)가 사출구(114)를 통해 저압 사출된다(e). Thereafter, the second mold 113 advances upward to form a molding space, and then the second member 130 is injected at low pressure through the injection port 114 (e).

다음으로, 제1 금형(111)과 제2 금형(113)이 형폐되어 제1, 제2 부재(120,130)를 소정형상으로 성형한다(f).Next, the first mold 111 and the second mold 113 are closed to mold the first and second members 120 and 130 into a predetermined shape (f).

이때, 제1 소재(120)와 제2 소재(130)는 동일한 위치에 각각 꺾임부(120a,130a)가 형성되고, 꺾임부(120a,130a)의 하측에 감압코어(140)의 감압면(141)이 맞닿게 된다.The bending portions 120a and 130a are formed at the same positions of the first and second materials 120 and 130 and the depression portions 120a and 130a of the decompression core 140 141).

제1 금형(111)과 제2 금형(113)이 완전 형폐된 직후, 제2 금형(113)에 설치된 감압코어(140)은 하측으로 후진된다(g).Immediately after the first mold 111 and the second mold 113 are completely closed, the decompression core 140 provided in the second mold 113 is moved backward (g).

감압코어(140)가 후진됨으로써 감압코어(140)와 맞닿은 제1, 제2 부재(120,130)의 꺾임부(120a,130a)에도 음압이 가해져서 주름의 발생이 방지된다.The negative pressure is applied to the bent portions 120a and 130a of the first and second members 120 and 130 that are in contact with the reduced pressure core 140 due to the backward movement of the reduced pressure core 140,

이후, 제1, 제2 금형(111,113)이 형개되고, 제2 금형(113)에 설치된 감압코어(140)도 제2 금형(113)에서 전진된 상태인 원래의 위치로 복원된다. 그리고, 제1 부재(120) 및 제2 부재(130)이 결합된 차량 내장제 제품이 취출된다(h).Thereafter, the first and second molds 111 and 113 are opened, and the decompression core 140 installed in the second mold 113 is also restored to its original position in the advanced state in the second mold 113. Then, the vehicle interior decoration product in which the first member 120 and the second member 130 are combined is taken out (h).

마지막으로, 기재인 제2 부재(130)의 테두리를 원단인 제1 부재(120)로 감싸는 작업을 후가공으로 진행한다(i).Finally, the process of wrapping the rim of the second member 130, which is a base material, with the first member 120, which is a raw material, proceeds with post-processing (i).

이와 같이 본 발명은 차량 내장재를 원단일체성형 방식으로 제조할 때에, 꺽임부에서 발생되는 주름을 방지하도록 꺽임부에 음압을 발생시키는 감압코어(140)을 설치함으로써 생산된 차량 내장재가 불량처리되지 않고 고품질을 유지할 수 있게 된다. As described above, according to the present invention, when the vehicle interior material is manufactured by the one-body molding method, the vehicle interior material produced by providing the decompression core 140 that generates negative pressure in the bent portion to prevent wrinkles generated in the folded portion is not defective High quality can be maintained.
