패드 발포 금형의 구조{STRUCTURE OF FIRING MOLD FOR A PAD}Structure of Pad Foam Mold {STRUCTURE OF FIRING MOLD FOR A PAD}

본 발명은 자동차용 시트나 가정용 소파 및 침구류에 들어가는 패드를 제작하기 위한 패드 발포 금형의 구조에 관한 것으로, 더욱상세하게는 상기 패드를 제작하기 위한 상틀과 하틀로 구성된 알루미늄 금형의 파팅라인(PARTTING LINE)을 에폭시 수지 처리를 함과 동시에 파팅라인에 가스순환로를 형성시키므로서 금형의 제작 공정기간을 줄이고, 파팅라인을 정확하게 맞출수 있으며 생산성에 따라 많이 접촉하여 발생되는 파팅라인의 에폭시 수지부분의 뒤틀림이나 마모를 용이하게 유지 보수를 하므로서 작업생산에 신속하게 대처할 수 있고, 발포성형시 일정한 가스 배출을 유도하여 불량률을 최소화시킬 수 있는 패드 발포 금형의 구조에 관한 것이다.The present invention relates to a structure of a pad foaming mold for manufacturing a pad for a car seat or a home sofa and bedding, and more particularly, a parting line of an aluminum mold consisting of a top frame and a heart for manufacturing the pad. By processing the epoxy resin and forming a gas circulation path in the parting line, the manufacturing process of the mold can be shortened, the parting line can be precisely aligned, and the warpage of the epoxy resin part of the parting line caused by a lot of contact with the productivity The present invention relates to a structure of a pad foam mold that can easily cope with work production by easily maintaining wear, and induce a constant gas discharge during foam molding to minimize a defective rate.

일반적으로 상틀과 하틀로 구성된 종래 패드 발포 금형의 파팅라인은 정밀도가 요구되므로 방전처리를 하여 사용하였으나 방전처리를 하기 위해서는 고가의 방전기를 구입해야하므로 많은 경비가 발생하고, 고가의 방전기 구입비를 줄이기 위해서 방전기를 구비한 공장에 방전처리를 의뢰하게 되는데 이는 일정한 시일이 걸려 제작시일이 오래걸리는 문제점이 발생하였다.In general, the parting line of the conventional pad foam mold composed of the upper frame and the heart is required to be discharged because of its precision, but in order to discharge the expensive discharger has to be purchased. The discharge process is requested to a factory equipped with a discharger, which takes a certain time, causing a problem in that the production takes a long time.

또한, 패드 발포 금형을 많이 사용함에 따라 파팅라인에 발생되는 마모를 수리하기 위해서 오랜 시간을 들여 방전처리를 해야 하므로서 작업의 지연을 가져오게 된다.In addition, as the pad foam mold is used a lot, it takes a long time to perform the discharge treatment to repair the abrasion generated in the parting line, thereby bringing about a delay in the work.

특히, 패드 발포 금형에 있어서, 고른 가스 배출이 이루어져야 일정한 형상의 패드가 형성되는데 패드 발포 금형의 방전처리된 파팅라인에 가스가 불규칙적으로 배출하게 되어 패트의 불량률이 증가시키는 문제점이 있었다.In particular, in the pad foaming mold, evenly discharged gas is formed to form a pad having a uniform shape. However, there is a problem in that gas is irregularly discharged in the discharged parting line of the pad foaming mold, thereby increasing the defective rate of the pad.

본 발명의 목적은 자동차용 시트나 가정용 소파 및 침구류에 들어가는 패드를 일정기간 질이 좋은 패드를 다량으로 생산하기 위해 사용되는 패드 발포 금형의 제작비용을 줄임과 동시에 많은 사용에 의해 발생되는 파팅라인의 마모를 용이하게 수리함으로서 작업의 지연을 막고 수리비용을 줄이며, 불규칙적인 가스누출을 막아 고르게 함으로서 불량률을 최소화하여 경제성을 향상시킬 수 있는 패드 발포 금형의 구조를 제공하는 데 있다.An object of the present invention is to reduce the production cost of the pad foaming mold used to produce a large amount of high quality pads for a certain period of time for the pads for the car seats, home sofas and bedding products, and at the same time a parting line generated by many uses It is to provide a structure of a pad foaming mold that can improve the economics by minimizing the defective rate by preventing the delay of the work by reducing the wear of the wear easily and reduce the repair cost, by preventing irregular gas leakage evenly.

상기 목적을 달성하기 위해 상틀과 하틀로 이루어진 금형의 파팅라인에 별도의 방전처리를 하지 않고 에폭시 수지처리를 하여 가스의 누출을 방지하므로서 수리가 용이하여 작업속도를 향상시키며, 파팅라인에 일정한 가스 순환로를 형성시켜 우레탄 발포 성형시 고른 가스 배출을 유도하여 패드 제작의 불량률을 최소화 할 수 있도록 한 것이다.In order to achieve the above object, it is easy to repair and improve the working speed by preventing the leakage of gas by performing epoxy resin treatment without separate discharge treatment on the parting line of the mold consisting of the upper frame and the heart, and improves the gas circulation path in the parting line. By forming the urethane foam to induce even gas discharge during molding to minimize the failure rate of the pad production.

상기한 목적을 달성하기 위한 수단으로서 본 발명의 구성은 도 1 내지 도 4에 나타낸 바와 같이,As a means for achieving the above object, the configuration of the present invention, as shown in Figures 1 to 4,

자동차용 시트나 가정용 소파 및 침구류에 들어가는 패드(1)를 형성시키기 위해 우레탄 수지를 넣을 수 있으며 패드의 일측형상을 형성할 수 있도록 형성된 하틀(10)과,The urtle resin which can be put in the urethane resin to form the pad (1) for the car seat or home sofa and bedding, and formed to form one side of the pad 10,

상기 하틀(10)의 일측 끝단부와 연결수단(21)에 의해 연결되어 개폐됨과 동시에 타측 끝단부에는 회전가능하도록 롤링핸들(22)을 구비하고, 하틀(10)과 결합시 패드(1)의 타측형상을 형성할 수 있도록 형성됨과 동시에 일정한 가스배출구(23)를 구비한 상틀(20)로 구성된 패드 발포 금형(100)에 있어서,One end of the heart 10 is connected to and opened by the connecting means 21 and the other end is provided with a rolling handle 22 so as to be rotatable, and when combined with the heart 10 of the pad (1) In the pad foaming die 100 formed of the upper frame 20 is formed so as to form the other side and provided with a constant gas outlet 23,

상기 패드 발포 금형(100)의 파팅라인을 형성하는 하틀(10)의 수직부와 수평부에 일정한 돌출부(11)(12)를 각각 형성시켜 상틀(20)의 결합시 가스순환로(30)를 형성시킨다.The protrusions 11 and 12 are formed on the vertical and horizontal portions of the heart 10 forming the parting line of the pad foaming die 100, respectively, thereby forming a gas circulation path 30 when the upper mold 20 is coupled. Let's do it.

상기 하틀(10)과 상틀(20) 결합시 패드 발포 금형(100)의 파팅라인을 형성하는 하틀(10)의 수직부와 수평부에 형성된 돌출부(11)(12)에 에폭시 수지 처리(40)를 함과 동시에 수직 및 수평 돌출부(11)(12)의 에폭시 수지처리된 파팅라인에 가스배출을 고루게 시키기 위해 일정한 간격으로 각각의 가스배출구(41)를 형성시킨다.Epoxy resin treatment (40) on protrusions (11) (12) formed on the vertical and horizontal portions of the heart (10) forming a parting line of the pad foam mold (100) when the heart (10) and the top frame (20) are combined. At the same time, the respective gas outlets 41 are formed at regular intervals to evenly discharge the gas in the epoxy resin treated parting lines of the vertical and horizontal protrusions 11 and 12.

이와 같이 구성된 본 발명의 패드 발포 금형(10)의 작용 및 효과를 실제사용상태를 들어 설명하면 다음과 같다.Referring to the operation and effects of the pad foaming mold 10 of the present invention configured as described above with an actual use state as follows.

자동차용 시트나 가정용 소파 및 침구류에 들어가는 패드(1)를 제작하기 위해 각각의 형상을 한 패드 발포 금형(100)의 하틀(10)에 우레탄 수지를 고루 놓고 상틀(20)을 결합시킨다. 이때 패드 발포 금형(100)의 파팅라인을 형성하는 하틀(10)의 수직 및 수평 돌출부(11)(12)에 에폭시 수지(40)를 부착시켜 상틀(20)과 결합시킨다.The urethane resin is evenly placed on the heart 10 of each of the pad foam molds 100 having the respective shapes in order to manufacture the pads 1 for the automobile seats or the home sofas and the bedding, and the upper frames 20 are combined. At this time, the epoxy resin 40 is attached to the vertical and horizontal protrusions 11 and 12 of the heart 10 forming the parting line of the pad foaming die 100, and is coupled with the upper frame 20.

결합된 금형(100)을 패드 제작용 장치(도시생략)에 올려 놓고 롤링핸들(22)을 이용하여 회전시키면서 가열시켜 우레탄 수지를 발포시킨다. 가열시 금형(100) 내부에 발생되는 가스가 상틀(20)에 형성된 가스배출구(23)를 통해 배출하게 된다.The combined mold 100 is placed on a pad manufacturing apparatus (not shown) and heated while rotating using a rolling handle 22 to foam the urethane resin. Gas generated in the mold 100 during heating is discharged through the gas outlet 23 formed in the upper frame (20).

이때 가스가 불규칙적으로 배출될 경우 불량이 발생하게 되는데 이런 불규칙적인 가스배출은 파팅라인을 중심으로 발생하게 된다.In this case, when the gas is irregularly discharged, a defect occurs. This irregular gas discharge occurs around the parting line.

그러나, 파팅라인에 에폭시 수지(40) 처리가 되어 있어 1차 및 2차 파팅라인을 형성하므로서 가스가 불규칙적으로 새지않고, 파팅라인에 형성된 가스순환로(30)에 의해 우레탄 발포 성형시 고른 가스가 배출되도록 유도되고, 1차 및 2차 파팅라인에 일정한 간격으로 형성된 각각의 가스배출구(41)를 통해 가스가 배출되므로 불규칙한 가스배출을 막아 불량을 줄이게 된다.However, the epoxy resin 40 is treated on the parting line, so that the gas is not leaked irregularly by forming the first and second parting lines, and even gas is discharged during urethane foam molding by the gas circulation path 30 formed in the parting line. The gas is discharged through each gas discharge port 41 formed at regular intervals in the primary and secondary parting lines so as to prevent irregular gas discharge, thereby reducing defects.

이와 같이 패드 발포 금형의 파팅라인에 불규칙적인 가스 배출을 막기 위해 에폭시 처리(40)를 하므로서 금형공정의 기간을 단축하고, 파팅라인의 방전가공에 필요한 고가의 방전기가 필요하지 않으며, 오랜 사용에 의해 파팅라인에 가스가 샐 경우 값싼 에폭시 처리(40)를 간편하게 할 수 있어 신속한 작업이 이루어져 생산성을 향상시키는 것이다.As such, the epoxy treatment 40 is performed to prevent irregular gas discharge in the parting line of the pad foaming die, thereby shortening the period of the mold process, and eliminating the need for expensive dischargers necessary for the discharge processing of the parting line. If the gas leaks to the parting line, the cheap epoxy treatment 40 can be easily performed, thereby improving productivity.

이상에서 설명한 바와 같이, 자동차용 시트나 가정용 소파 및 침구류에 들어가는 패드를 제작하기 위한 상틀과 하틀로 구성된 알루미늄 금형의 파팅라인를 에폭시 수지 처리를 함과 동시에 파팅라인에 가스순환로를 형성시키므로서 금형의 제작 공정기간을 줄이고, 파팅라인 마모에 대한 수리가 간편하고 용이하여 신속하게 대처할 수 있으며, 발포성형시 일정한 가스 배출로 인해 불량률을 최소화시켜 생산성이 향상되는 효과가 있다.As described above, the parting line of the aluminum mold consisting of the upper frame and the heartl for producing pads for automobile seats, home sofas and beddings is treated with epoxy resin and the gas circulation path is formed on the parting line. Shortening the manufacturing process, repairing part line wear is easy and easy to cope quickly, and minimizes the defective rate due to the constant gas discharge during foaming has the effect of improving productivity.
