도 1은 종래 기술에 따른 세탁기의 일부가 분해 도시된 사시도이고, 도 2는 종래 기술에 따른 디스플레이 패널의 부착 상태가 도시된 단면도이다.1 is an exploded perspective view illustrating a part of a washing machine according to the prior art, and FIG. 2 is a cross-sectional view illustrating an attachment state of the display panel according to the prior art.

종래의 세탁기는 도 1에 도시된 바와 같이 케이스(2) 상부에 세탁물이 세탁조(4) 내부로 유,출입되도록 투입홀(h)이 형성되고, 상기 투입홀(h)에는 상기 세탁조(4)로부터 세탁물의 이탈을 방지할 수 있도록 커버(6)가 설치되며, 상기 커버(6)의 전방에는 세탁기의 작동을 제어하는 전장부품 및 조작노브(8)와 세탁기의 작동상태를 알려주는 LED 등의 표시장치(9)가 내장된 컨트롤패널(10)이 고정된다.In the conventional washing machine, as shown in FIG. 1, an injection hole (h) is formed in the upper part of the case (2) to allow the laundry to flow into and out of the washing tank (4), and the washing tank (4) in the injection hole (h). The cover 6 is installed to prevent the laundry from being separated from the laundry, and the front of the cover 6 includes electronic parts for controlling the operation of the washing machine, an operation knob 8, and an LED indicating the operating state of the washing machine. The control panel 10 in which the display device 9 is incorporated is fixed.

그리고, 상기 컨트롤패널(10) 상측에는 디스플레이 패널(20)이 부착되는데, 상기 디스플레이 패널(20)은 도 2에 도시된 바와 같이 상기 컨트롤패널(10) 상측에 고정되어 상기 LED 등의 표시장치(9)를 통하여 세탁기의 작동상태를 사용자가 볼 수 있는 표시창(12a)이 일체로 형성된 고정패널(12)과, 상기 고정패널(12)의 상면에 부착되어 사용자가 직접 상기 조작노브(8) 측으로 작동력을 전달할 수 있도록 3차원 형상으로 돌출된 조작버튼(14a)이 형성된 조작필름(14)과, 상기 고정패널(12)의 배면 측에 설치되어 문자 또는 기호가 인쇄된 인쇄패널(16)로 이루어진다.In addition, a display panel 20 is attached to an upper side of the control panel 10, and the display panel 20 is fixed to an upper side of the control panel 10 as shown in FIG. 2. 9) the display panel (12a) is formed integrally with the display window (12a) that the user can see the operating state of the washing machine through, and is attached to the upper surface of the fixing panel 12, the user directly to the operation knob (8) side It consists of a control film 14 formed with a control button 14a protruding in a three-dimensional shape so as to transmit the operating force, and a printing panel 16 is installed on the back side of the fixed panel 12 and printed with letters or symbols .

상기 디스플레이 패널(20)은 디자인 측면에서 외관을 보다 고급스럽게 세련되게 보여지도록 상면에 문자 또는 기호가 인쇄된 인쇄패널(16)이 상기 고정패널(12)의 배면에 위치되도록 설치된다.The display panel 20 is installed such that a printed panel 16 having letters or symbols printed on the upper surface of the display panel 20 is positioned on the rear surface of the fixing panel 12 in order to show the appearance more elegantly and elegantly in terms of design.

여기서, 상기 조작버튼(14a)은 PC(Poly-carbonate) 또는 PET(Polyethylene Terephthalate) 재질의 평평한 조작필름(14)에 열을 가하고, 진공 흡착함으로 상측으로 볼록하게 돌출되도록 열성형되거나, 연속적인 프레스 가공을 통하여 볼록하게 돌출되도록 성형된다.Here, the operation button 14a is heat-formed or continuously presses to apply heat to the flat operation film 14 made of polycarbonate (PC) or polyethylene terephthalate (PET), and protrude convexly upward by vacuum adsorption. It is shaped to protrude convexly through processing.

상기와 같이 성형된 조작필름(14)은 상기 고정패널(12)이 인서트 사출될 때 배면에 바인더(일면 본드)가 입혀진 조작필름(14)이 금형 내부 일측에 고정되고, 상기 금형 내부로 사출 수지가 삽입됨으로 사출 수지의 열온도로 상기 조작필름(14)에 입혀진 바인더가 열변형되면서 상기 고정패널(12)의 상면에 부착될 수도 있다.In the operation film 14 formed as described above, the operation film 14 having a binder (one side bond) coated on the back surface is fixed to one side of the mold when the fixing panel 12 is inserted into the mold, and the injection resin is injected into the mold. By inserting the binder resin coated on the operation film 14 at the thermal temperature of the injection resin may be attached to the upper surface of the fixing panel 12 while being thermally deformed.

한편, 상기 컨트롤패널(10)의 상면에는 상기 조작노브(8) 및 표시장치(9)가 실장된 PCB(7)가 내장되는 지지부(10a)가 형성되고, 상기 지지부(10a)에는 상기 고정패널(12)이 장착되는 제1홈(10a')과 그 내측에 상기 인쇄패널(16)이 장착되는 제2홈(10b)이 형성된다.On the other hand, the upper surface of the control panel 10 is formed with a support portion (10a) in which the PCB (7) on which the operation knob 8 and the display device 9 is mounted is formed, and the fixing panel (10a) A first groove 10a 'on which the 12 is mounted and a second groove 10b on which the printing panel 16 is mounted are formed.

따라서, 상기 인쇄패널(16)의 양단이 상기 컨트롤패널(10)의 지지부(10a)에 형성된 제2홈(10b)에 고정되고, 상기 조작필름(14)이 부착된 고정패널(12)은 상기 컨트롤패널(10)의 지지부(10a)에 형성된 제1홈(10a')에 끼움 설치된다.Therefore, both ends of the printing panel 16 is fixed to the second groove 10b formed in the support part 10a of the control panel 10, and the fixing panel 12 to which the operation film 14 is attached is It is fitted into the first groove (10a ') formed in the support portion (10a) of the control panel 10.

그러나, 종래 기술에 따른 세탁기의 디스플레이 패널(20)은 문자 또는 기호가 인쇄된 인쇄패널(16)을 고정패널(12) 배면에 설치하기 위하여 인쇄패널(16)의 양단이 컨트롤패널(10)의 지지부(10a)에 고정하기 위한 별도의 고정 구조가 추가되는 문제점이 있다.However, in the display panel 20 of the washing machine according to the related art, both ends of the printing panel 16 are connected to the control panel 10 in order to install the printing panel 16 on which the letters or symbols are printed on the rear surface of the fixing panel 12. There is a problem that a separate fixing structure for fixing to the support 10a is added.

또한, 고정패널(12)과 인쇄패널(16) 사이에 공간부(A)가 형성됨으로 온수 세탁시 공간부(A) 사이로 습기가 침투되어 사용자가 인쇄패널(16)의 내용을 식별할 수 없게 되는 문제점이 있다.In addition, since the space A is formed between the fixed panel 12 and the printing panel 16, moisture penetrates into the space A during hot water washing, so that the user cannot identify the contents of the printing panel 16. There is a problem.

한편, 상기한 문제점을 해결하기 위하여 최근에는 상기 인쇄패널(16) 대신 문자 또는 기호가 인쇄된 인쇄필름(미도시)을 상기 고정패널(16)이 사출되는 금형(미도시)에 삽입하고, 상기 인쇄필름(미도시)의 상면 측 금형(미도시) 내부로 수지를 유입시킴으로 상기 고정패널(16)과 일체로 형성하는 것도 가능하다.On the other hand, in order to solve the above problems, in recent years, instead of the printing panel 16, a printing film (not shown) printed with letters or symbols is inserted into a mold (not shown) to which the fixing panel 16 is injected, and It is also possible to integrally form the fixing panel 16 by introducing a resin into the mold (not shown) on the upper surface side of the printing film (not shown).

이 경우, 상기 금형(미도시) 내부에 일측에는 조작필름(14)이 위치되고 타측에는 인쇄필름(미도시)이 위치되도록 하고 상기 조작필름(14)과 인쇄필름(미도시)사이로 수지가 유입되는데, 상기 수지는 상기 인쇄필름(미도시)이 위치된 금형(미도시)을 통해 내부로 유입됨으로 상기 인쇄필름(미도시)이 유동되는 수지에 의해 이동되어 정확한 위치에 부착되지 못하는 문제점이 있다.In this case, the operation film 14 is positioned on one side and the printing film (not shown) is located on the other side inside the mold (not shown), and resin flows between the operation film 14 and the printing film (not shown). The resin is introduced into the inside of the mold (not shown) in which the print film (not shown) is moved, and thus the print film (not shown) is moved by the resin in which the print film is not moved. .

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 고정패널 인서트 사출시 인쇄필름을 고정패널의 정확한 위치에 일체로 부착하여 디스플레이 패널을 제작할 수 있는 세탁기의 디스플레이 패널용 사출금형을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and provides an injection mold for a display panel of a washing machine that can produce a display panel by integrally attaching the printing film to the correct position of the fixed panel when the fixed panel insert injection.
