Description

일체형 대형용기의 압축 성형방법{omitted}Compression molding method of integrated large container {omitted}

본 발명은 원형이나 사각형의 대형용기를 P.E원료로 일체형이 되도록 압축성형하기 위한 것으로, 더욱 상세하게는 중앙금형과 상,하부금형이 5∼10mm의 간격을 두고 정지된 상태에서 원료를 공급하여 일체형 대형 용기를 압축성형할 수 있도록하는 일체형 대형용기의 압축 성형방법에 관한 것이다.The present invention is for compression molding a large container of a circular or rectangular shape to be integrated with PE raw material, more specifically, the central mold and the upper and lower molds are supplied by supplying the raw materials in a stopped state at intervals of 5 to 10 mm. The present invention relates to a compression molding method of an integrated large container capable of compression molding a large container.

종래의 원형정화조 또는 사각형의 오수처리조와 같은 대형용기는 외부의 압력을 견딜 수 있도록 하기 위하여 외부에 가로와 세로 방향으로 바둑판무늬의 보강 지주를 형성하게되므로 한번에 성형할 수 없어서 3조각 또는 4조각으로 분리하여 사출한 후 융착기를 통하여 대형용기를 만들게 된다.Large containers, such as conventional round septic tanks or rectangular sewage treatment tanks, form a checkered reinforcement strut in the horizontal and vertical directions on the outside to withstand external pressure. After separation and injection, large containers are made through the fusion machine.

그러나 융착부분이 견고하지 못하여 사용될 때 토압을 견지지 못하고 융착부분이 벌여져서 내용물이 토양에 유출되므로 환경을 오염시키는 원인이 된다.However, when the welded part is not strong, the earth pressure cannot be established and the welded part is opened and the contents are leaked into the soil, which causes pollution of the environment.

이러한 결점을 방지하기 위한 실용신안등록 제131357호가 제안되어 일체형으로 대형용기를 성형할 수 있게 되었으나, 대형형기의 크기(중량이 100∼400kg)가 너무 커서 성형시 발생되는 압력으로 상부금형(1)과 하부금형(2)이 외측으로 밀리면서 오래 사용할 수 없는 결점이 발생한다.Utility model registration No. 131357 has been proposed to prevent such drawbacks, so that it is possible to form large containers in one piece, but the size of the large molds (weight 100-400 kg) is too large and the upper mold (1) As the lower mold 2 is pushed outward, a defect that cannot be used for a long time occurs.

또한 대형용기를 성형하기 위해서는 용융된 재료를 수작업으로 옮겨서 금형의 내부에 공급한 후 하부금형과 중앙금형이 상승하여 일체형의 용기를 성형하기 위해서는 금형이 조립된 상태에서 오랜시간동안 성형압력을 유지하게 된다.Also, in order to form a large container, the molten material is moved manually and supplied to the inside of the mold, and then the lower mold and the center mold are raised to maintain the molding pressure for a long time while the mold is assembled to form an integrated container. do.

이때 약500∼800톤의 성형압력이 금형에 가해지므로 금형이 쉽게 망가지고, 금형을 이송시키는 가이드대 또는 레일이 외측으로 휘어져서 사용할 수 없게되는결점이 있다.At this time, since a molding pressure of about 500 to 800 tons is applied to the mold, the mold is easily broken, and the guide stand or rail for transferring the mold may be bent outward to be used.

따라서 금형의 전체면에 균일한 압력이 작용되지 못하고 편중압력이 작용되므로 원료가 균일하게 공급되지 않아서 균일한 두께를 갖는 대형용기를 제공할 수 없게된다.Therefore, since the uniform pressure is not applied to the entire surface of the mold and the biasing pressure is applied, the raw material is not uniformly supplied, and thus a large container having a uniform thickness cannot be provided.

또한 성형이 완성된 후에는 금형이 서로 분리되기 위해서 많은 힘이 소모되며 금형의 성형홈(1',2')에서 잘 분리되지 않아서 원료중에 조그만 이물질만 포함되어 있어도 쉽게 찢어지는 결점이 발생한다.In addition, after the molding is completed, a large amount of force is consumed to separate the molds from each other, and the molds are not easily separated from the molding grooves 1 'and 2' of the mold, so that even if only small foreign substances are included in the raw materials, defects are easily broken.

또한 상기와 같은 인젝션 성형방법은 설비비가 고가로 소모되는 반면에 수작업으로 생산성이 저하되며, 잦은 수리로 인하여 보수 및 유지비용이 많이 소모되는 결점이 있다.In addition, the injection molding method as described above has the drawback that, while equipment costs are consumed at a high cost, productivity is reduced by manual labor, and maintenance and maintenance costs are consumed due to frequent repairs.

용융된 재료를 자동으로 공급하여 일체형 대형용기를 압축성형방법으로 성형할 수 있도록 하는 것이다.It is to automatically supply the molten material to form an integral large container by compression molding method.

본 발명은 중앙금형의 위치를 제어하는 간격유지 실린더에 의하여 상, 하부금형이 5∼10mm의 간격을 두고 정지하면 외부에서 용융된 재료를 자동으로 공급한후 대형용기의 두께를 균일하게 성형할 수 있도록 하는 것이다.According to the present invention, when the upper and lower molds stop at intervals of 5 to 10 mm by the interval maintaining cylinder that controls the position of the center mold, the molten material can be uniformly formed after the molten material is automatically supplied from the outside. To ensure that

본 발명은 중앙금형의 위치를 제어하는 간격유지 실린더에 의하여 성형된 대형용기를 간편하게 분리할 수 있도록 하는 것이다.The present invention is to be able to easily separate the large container formed by the spacing cylinder to control the position of the center mold.

본 발명은 중앙 가이드대의 하측에서 실린더축을 구동시켜 간격유지 실린더로 중앙금형이 상부금형과 하부금형에 5∼10mm의 간격으로 벌어지도록 하는 중앙금형 세팅과정과,The present invention is a center mold setting process for driving the cylinder shaft in the lower side of the center guide stand so that the center mold is spaced apart at intervals of 5 to 10 mm in the upper mold and the lower mold by the interval maintaining cylinder,

중앙금형을 세팅한 후 원료를 공급배관으로 상부금형과 하부금형에 공급하는 원료 공급과정과,After the central mold is set, the raw material supply process of supplying the raw material to the upper mold and the lower mold by supply pipe

하부틀(5)이 상승하면서 일체형의 하부금형(2)이 상승하게 되며, 하부금형(2)이 중앙금형(3)의 하측을 지지하여 상부금형(1)과 하부금형(2)이 10∼20mm의 간격을 두고 정지하도록 한다.As the lower mold 5 rises, the integrated lower mold 2 rises, and the lower mold 2 supports the lower side of the central mold 3 so that the upper mold 1 and the lower mold 2 are 10 to 10, respectively. Stop at 20mm intervals.

이때 하부틀(5)의 전방에 설치된 가이드대(11)는 중앙금형(3)의 중앙 가이드대(10)의 내부에 안내되며 상승한다.At this time, the guide stand 11 installed in front of the lower frame 5 is guided inside the center guide stand 10 of the center mold 3 and rises.

②중앙금형의 세팅과정② Setting process of central mold

중앙 가이드대(10)의 양측에 설치된 간격유지 실린더(12)의 실린더축(12')이 상승하여 중앙 가이드대(10)의 하측을 밀어 올려 센서(S)에 감지될 때까지 구동시킨다.The cylinder shaft 12 ′ of the space keeping cylinder 12 provided on both sides of the center guide stand 10 is raised to drive the lower side of the center guide stand 10 until it is detected by the sensor S.

간격유지 실린더(12)의 실린더축(12')이 중앙 가이드대(10)의 하측에서 중앙금형(3)을 상승시켜 도 2 및 도 4 와 같이 중앙금형(3)이 상부금형(1) 및 하부금형(2)이 대형용기(13)를 성형하는 공간을 제외하고 5-10mm의 간격을 갖도록 세팅된다.The cylinder shaft 12 ′ of the space keeping cylinder 12 raises the center mold 3 from the lower side of the center guide stand 10, so that the center mold 3 is the upper mold 1 and 3 as shown in FIGS. 2 and 4. The lower mold 2 is set to have an interval of 5-10 mm except for the space for forming the large container 13.

③ 원료공급과정③ Raw Material Supply Process

중앙금형(3)의 양측으로 상부금형(1)과 하부금형(2)이 5∼10mm의 간격을 갖도록 설치된 후 도시되지 않은 외부에서 용융된 원료가 공급배관(8, 9)을 통하여 상부금형(1)과 하부금형(2)의 내부에 원료(20)를 공급하게 된다.The upper mold 1 and the lower mold 2 are installed at both sides of the central mold 3 so as to have a gap of 5 to 10 mm, and then raw materials melted from the outside, not shown, are supplied to the upper mold (8, 9). 1) and the raw material 20 is supplied to the inside of the lower mold (2).

④ 압축성형과정④ Compression Molding Process

원료(20)의 공급이 완료되면 간격유지 실린더(12)를 구동시켜 실린더축(12')을 후진시킴과 동시에 유압실린더(18)를 구동시켜 하부틀(5)를 상승시키게 된다.When the supply of the raw material 20 is completed, the spacing cylinder 12 is driven to reverse the cylinder shaft 12 ′ and the hydraulic cylinder 18 is driven to raise the lower frame 5.

하부틀(5)이 상승되면서 중앙금형(3)과 상부금형(1)이 하부금형(2)과 함께 원료(20)를 동시에 압축하면서 도 3 과 같이 대형용기(13)를 성형하게 된다.As the lower mold 5 is raised, the central mold 3 and the upper mold 1 simultaneously form the large container 13 as shown in FIG. 3 while simultaneously compressing the raw material 20 together with the lower mold 2.

여기서 원료(20)는 상부금형(1)과 하부금형(2) 및 중앙금형(3)의 전체면에 균일하게 공급된 후 압축성형하므로 원료(20)가 균일한 압력을 받아 일정한 두께의 대형용기(13)를 성형할 수 있는 것이다.Here, since the raw material 20 is uniformly supplied to the entire surface of the upper mold 1, the lower mold 2, and the center mold 3, and then compression molding, the raw material 20 is subjected to uniform pressure and a large container having a constant thickness.

중앙 가이드대(10)가 들어올려지면서 중앙금형(3)이 상승하여 하부금형(2)과 대형용기(13)가 분리되도록 하는 것이다.As the center guide stand 10 is lifted, the center mold 3 is raised so that the lower mold 2 and the large container 13 are separated.

하부금형(2)의 하강과 동시에 중앙금형(3)이 하강하게되고 안내축(14)의 너트(17)가 멈춤링(16)에 걸리면서 멈추게된다.At the same time as the lower mold 2 is lowered, the central mold 3 is lowered and the nut 17 of the guide shaft 14 is stopped by the stop ring 16.

⑥ 탈형과정⑥ Demoulding process

상부금형(1)과 하부금형(2) 및 중앙금형(3)을 분리한 후에는 외부에서 공기호스(21)를 통하여 공기를 공급하면 노즐(20)에서 중앙금형(3)의 외측으로 압축공기를 공급하게 된다.After separating the upper mold (1), the lower mold (2) and the central mold (3), when the air is supplied through the air hose 21 from the outside, the compressed air from the nozzle 20 to the outside of the central mold (3) Will be supplied.

그러면 압축공기가 대형용기(13)를 외측으로 밀어내어 대형용기(13)를 탈형시키게 된다.Then, the compressed air pushes the large container 13 outward to demold the large container 13.

본 발명은 용융된 재료를 자동으로 공급하여 일체형 대형용기를 압축성형방법으로 한번에 자동성형할 수 있도록 하는 것이다.The present invention is to automatically supply the molten material so that the integrated large-sized container can be automatically molded at once by the compression molding method.

본 발명은 중앙금형의 위치를 제어하는 간격유지 실린더에 의하여 상, 하부금형이 5∼10mm의 간격을 두고 정지하면 외부에서 용융된 재료를 자동으로 공급한후 대형용기의 두께를 균일하게 성형할 수 있도록 하는 것이다.According to the present invention, when the upper and lower molds stop at intervals of 5 to 10 mm by the interval maintaining cylinder that controls the position of the center mold, the molten material can be uniformly formed after the molten material is automatically supplied from the outside. To ensure that

본 발명은 중앙금형의 위치를 제어하는 간격유지 실린더에 의하여 성형된 대형용기를 간편하게 분리할 수 있도록 하는 것이다.The present invention is to be able to easily separate the large container formed by the spacing cylinder to control the position of the center mold.
