Description

진공성형기용 금형의 통기장치 { Ventilation system of mold for makingmachine }Ventilation system of mold for vacuum molding machine {Ventilation system of mold for makingmachine}

본 발명은 진공 성형기에 설치되는 금형의 통기장치에 관한 것으로, 특히 금형의 내부로 공기가 유입되도록 형성함으로써, 진공성형기를 통한 성형물의 제작 과정에서 진공상태의 금형 내부에 공기가 유입되도록 하여, 금형의 표면에 밀착, 경화된 성형물을 용이하게 금형에서 분리할 수 있고, 분리작업 중에 성형물의 변형이나 손상을 미연에 방지하도록 한 것이다.The present invention relates to a venting device for a mold installed in a vacuum molding machine, and in particular, by forming the air to enter the inside of the mold, the air is introduced into the mold in a vacuum state in the manufacturing process of the molding through the vacuum molding machine, The molded product, which is in close contact with the surface of the mold and can be easily removed from the mold, prevents deformation or damage of the molded product in advance.

일반적으로 진공 성형기는 플라스틱 등의 수지재를 성형하기 위한 기계 장치로서, 근래에 와서 이러한 성형물은 전반적인 산업의 각종의 분야의 다양한 제품과 품목에 적용하여 사용되고 있는 추세이다.Generally, a vacuum molding machine is a mechanical device for molding a resin material such as plastic, and in recent years, such moldings have been applied to various products and items in various fields of the general industry.

이러한 진공 성형기는 주로, 제조하고자 하는 형상과 모양의 금형을 제작하고, 제작된 금형을 진공 성형기에 설치한 후에, 고온으로 연화된 수지재의 시트(Sheet)를 하방으로 이송하여 금형의 상면에 위치되도록 하고, 금형 내부의 공기를 배출하도록 한다.Such a vacuum molding machine mainly produces a mold having a shape and a shape to be manufactured, installs the manufactured mold in a vacuum molding machine, and then transfers a sheet of a resin material softened at a high temperature downward so as to be positioned on an upper surface of the mold. And exhaust the air inside the mold.

그리고 금형 내부의 공기를 배출하게 되면, 상기 연화된 시트는 일정한 형상의 금형의 표면에 밀착되고, 밀착된 시트를 냉각시켜 경화되도록 하고, 경화된 시 트와 금형을 분리하도록 하고 있다.And when the air inside the mold is discharged, the softened sheet is in close contact with the surface of the mold of a predetermined shape, to cool the adhered sheet to be cured, and to separate the cured sheet and the mold.

그러나 상기한 종래의 진공 성형기의 금형은, 금형의 표면에 시트가 밀착되어 냉각, 경화되고, 금형에서 성형물을 분리할 경우에, 금형 내부가 진공 상태로 유지되기 때문에, 금형에서 성형물을 분리하는 작업이 어렵고 작업시간이 지연되는 문제점이 발생하였다.However, in the mold of the conventional vacuum molding machine, the sheet is adhered to the surface of the mold to cool and harden, and when the mold is separated from the mold, the inside of the mold is kept in a vacuum state, so that the mold is separated from the mold. This problem is difficult and the work time is delayed.

또한, 구 형태의 성형물이나 음각 등의 굴곡이 심한 성형물 등을 금형에서 무리하게 분리할 경우에, 성형물이 일그러지거나 찌그러지는 등의 변형과 손상에 대한 단점이 나타나고 있었다.In addition, when excessively separating a spherical shaped article or a highly curved molded article such as an intaglio, etc., the disadvantages of deformation and damage such as distortion or distortion of the molded article appear.

따라서, 상기한 문제점을 해결하기 위한 본 발명은, 진공 성형기에 설치되는 금형의 내부로 공기를 유통시킬 수 있도록 형성함으로써, 진공 상태의 금형 내부로 공기가 유입되어, 금형 표면에서 성형물을 분리하는 작업이 신속하고 편리할 수 있을 뿐만 아니라, 금형과 성형물의 분리작업 과정에서 성형물이 일그러지거나 찌그러지는 등의 변형과 손상을 방지하도록 하는데 그 목적이 있는 것이다.Therefore, the present invention for solving the above problems, by forming so that the air can be flowed into the inside of the mold installed in the vacuum molding machine, the air flows into the mold in a vacuum state, the operation to separate the molding from the mold surface In addition to being quick and convenient, the object is to prevent deformation and damage such as distortion or distortion of the molding during the separation operation of the mold and the molding.

이상에서 설명한 바와 같이 본 발명은, 진공성형기의 금형을 하강하여 성형물과 분리하는 작업 과정에서, 금형의 내부로 공기가 유입될 수 있도록 형성하기 때문에, 금형 표면에서 성형물을 분리하는 작업이 신속하고 원활하게 진행될 수 있을 뿐만 아니라, 금형과 성형물의 분리작업에서 발생할 수 있는 변형과 손상 등의 불량률을 최소화할 수 있도록 한 유익한 발명인 것이다.As described above, the present invention is formed so that the air flows into the mold during the operation of lowering the mold of the vacuum molding machine to separate from the molding, it is quick and smooth to separate the molding from the mold surface In addition to being able to proceed, it is an advantageous invention to minimize the defect rate, such as deformation and damage that can occur in the separation operation of the mold and the molding.

도 1은 본 발명의 진공 성형기의 작동 상태를 나타낸 개략도이고, 도 2는 본 발명의 실시예를 보인 단면도이다.1 is a schematic view showing an operating state of a vacuum molding machine of the present invention, Figure 2 is a cross-sectional view showing an embodiment of the present invention.

이하, 본 발명에 따른 구성 및 작용효과를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and effect according to the present invention will be described in detail with reference to the accompanying drawings.

도 1과 도 2에 도시된 바와 같이, 본 발명은 금형 내부에 공기를 유통시키도록 하는 통기부재(10)와, 상기 통기부재(10)를 제어하도록 하는 개폐부재(20)로 구성된다.As shown in Figure 1 and 2, the present invention is composed of a vent member 10 for circulating the air in the mold, and the opening and closing member 20 for controlling the vent member 10.

상기 통기부재(10)는 금형의 측면에 공기가 유입되도록 하는 통기부(11)와, 상기 통기부(11)로 유입된 공기를 금형 상측으로 유입되도록 하는 금형 통공(12)을 형성한다.The vent member 10 forms a vent part 11 through which air is introduced into a side of the mold, and a mold through hole 12 through which air introduced into the vent part 11 flows into the upper part of the mold.

상기 개폐부재(20)는 상기 통기부(11)의 말단에 설치되어 개폐되는 개폐밸브(21)와, 금형의 하강을 감지하도록 한 감지부(22)와, 상기 감지부(22)의 입력신호에 의하여 상기 개폐밸브의 구동을 전송하도록 하는 제어부(23)를 형성한다.The opening and closing member 20 is installed at the end of the vent 11, the opening and closing valve 21 to open and close, the sensing unit 22 to detect the falling of the mold, and the input signal of the detection unit 22 By the control unit 23 to transmit the drive of the on-off valve is formed.

미설명 부호 1은 금형이고, 2는 시트이고, 3은 공기배출장치의 팬이다.Reference numeral 1 is a mold, 2 is a sheet, and 3 is a fan of the air exhauster.

이상에서 설명한 바와 같은 본 발명의 작용 및 효과를 첨부된 도면에 의거하여 살펴보면 다음과 같다.Looking at the operation and effect of the present invention as described above based on the accompanying drawings as follows.

도 1의 (가)에 도시된 바와 같이, 진공성형기에 설치된 금형(1)으로 성형물을 제작하는 과정은, 상기 금형(1)의 표면으로 연화된 시트(2)가 하강하게 되고, 도1의 (나)에 도시된 바와 같이, 하강된 시트(2)는 금형 표면에 밀착되고, 이때 별도의 수단인 공기배출장치의 팬(3)의 구동으로 금형 내부의 공기가 배출되어, 금형 표면에 시트(2)가 보다 견고하게 밀착되는 것이다.As shown in (a) of FIG. 1, in the process of manufacturing the molded product with the mold 1 installed in the vacuum molding machine, the sheet 2 softened to the surface of the mold 1 is lowered, and as shown in FIG. As shown in (b), the lowered sheet 2 is in close contact with the mold surface, and at this time, the air inside the mold is discharged by driving the fan 3 of the air discharge device, which is a separate means, and the sheet is placed on the mold surface. (2) is to stick more firmly.

그리고, 도 1의 (다)에 도시된 바와 같이, 상기 금형(1)과 금형 표면에서 냉각, 경화된 성형물을 분리할 경우, 금형(1)을 하강시키도록 하여 분리 작업을 진행하고, 이때 금형 내부가 진공상태이고 금형 표면과 성형물이 견고하게 밀착된 상태로서, 분리 작업이 어렵기 때문에, 상기 통기부재(10)를 개방하는 것이다.And, as shown in (c) of Figure 1, when separating the molded and cooled molding from the mold 1 and the mold surface, the mold 1 is lowered to proceed with the separation operation, at this time Since the inside is in a vacuum state and the mold surface and the molded product are tightly adhered, and the separation operation is difficult, the vent member 10 is opened.

상기 개폐부재(20)의 감지부(22)에서 금형의 하강을 감지하고 상기 제어부(23)에 신호를 입력, 전송하게 되면, 상기 제어부(23)에서 신호를 판단하여 상기 개폐밸브(21)에 구동신호를 명령, 전송한다.When the sensing unit 22 of the opening and closing member 20 detects the falling of the mold and inputs and transmits a signal to the control unit 23, the control unit 23 determines a signal to the open / close valve 21. Command and transmit the drive signal.

상기 제어부(23)의 신호에 의하여 상기 개폐밸브(21)가 구동하여 상기 통기부재(10)의 통기부(11)를 개방하게 되면, 별도의 수단인 공기배출장치의 팬(3)의 구동으로 금형 내부에 공기를 강제로 유입시켜, 성형물과 분리하기 위한 금형(1)의 하강 시에, 성형물의 함몰이나 파손 등의 불량을 방지할 수 있는 것이다.When the on-off valve 21 is driven by the signal of the control unit 23 to open the vent 11 of the vent member 10, the fan 3 of the air discharge device as a separate means is driven. It is possible to prevent defects such as dents or breakage of the molded product at the time of lowering the mold 1 to force air into the mold and separate the molded product from the molded product.

그리고, 별도의 공기배출장치의 팬(3)의 작동에 의해, 금형 내부에 유입된 공기는 금형의 통공(12)을 통하여 금형과 성형물 사이 공간으로 이송되기 때문에, 금형과 성형물의 분리 작업은 불량품 발생 없이 원활하게 진행될 수 있는 것이다.In addition, since the air introduced into the mold is transferred to the space between the mold and the molding through the through hole 12 of the mold by the operation of the fan 3 of the separate air discharge device, the separation work of the mold and the molding is defective. It can proceed smoothly without any occurrence.
