It is connected to the hydraulic cylinder 24 on both sides to enable the opening of the upper mold (4, 5) to both sides.
상기 밀림방지홈(17)에 삽입되는 밀림방지대(18)는 유압실린더(20)에 연결되어 안내홈(19)에서 상, 하측으로 이동되도록 설치한다.The slide guard 18 inserted into the slide preventing groove 17 is connected to the hydraulic cylinder 20 and installed to move up and down in the guide groove 19.
이러한 구성으로 이루어진 본 발명은 도 1 과 같은 상태에서 용융장치에 의하여 P.E를 녹인 원료(29)를 400kg정도 하부금형(3)에 공급하고 유압실린더(6)에 유압을 통하여 실린더축(7)을 작동시키면 받침대(2)가 상하이송장치(A)에 의하여 서서히 상승하게 된다.According to the present invention having the above configuration, the raw material 29 in which PE is melted by the melting apparatus in the state as shown in FIG. 1 is supplied to the lower mold 3 by about 400 kg, and the cylinder shaft 7 is hydraulically supplied to the hydraulic cylinder 6. When activated, the pedestal 2 is gradually lifted by the shanghai conveying device (A).
상하이송장치(A)에 의하여 받침대(2)가 상승하여 상부금형(4, 5)의 내부로 하부금형(3)이 진입하게 된다.The pedestal 2 is lifted by the shanghai conveying device (A) to enter the lower mold (3) into the upper mold (4, 5).
그러면 원료(29)는 내부에서 전체면에 서서히 골고루 공급되어지며 상부금형(4, 5)의 하측이 걸림홈(9)에 진입하게 되면서 걸림턱(10)에 걸리게 되므로 가이드대(8)에 의하여 사면에서 상승되는 하부금형(3)에 의해 발생되는 프레스 압력에 의하여 상부금형(4, 5)이 이등분 되어 있어서 양측으로 벌어지려고 하는 힘이 작용하게 되나 걸림턱(10)에 걸려서 외측으로 벌어질 수 없게 된다.Then, the raw material 29 is supplied evenly to the entire surface from the inside, and the lower side of the upper molds 4 and 5 enters the catching groove 9 and is caught by the catching jaw 10 so that the guide stand 8 is provided. The upper mold (4, 5) is divided into two by the press pressure generated by the lower mold (3) that is raised from the slope, so that the force to open to both sides acts but can be caught outside the locking jaw (10) There will be no.
또한 상측부에서도 상부금형(4, 5)이 벌어지려고 하나 유압실린더(20)에 의하여 밀림방지대(18)가 하강하여 밀림방지홈(17)에 결합되므로 밀림방지대(18)는 후방이 상부몸체(21)의 안내홈(19)에 위치하게 되어 결국 상부몸체(4,5)가 외측으로 벌어지려고 하는 힘을 막아주게 되므로 정화조(30)의 성형이 온전하게 이루어지는 것이다.In addition, the upper mold (4, 5) in the upper side, but also to prevent the sliding bar (18) is lowered by the hydraulic cylinder (20) is coupled to the anti-roll groove (17), the slide bar (18) is rear upper Since it is positioned in the guide groove 19 of the body 21 to prevent the force to be opened to the upper body (4, 5) to the outside, the molding of the septic tank 30 is made intact.
정화조(30)와 같은 대형용기의 성형이 이루어지면 상하이송장치(A)를 도 3에서와 같이 걸림턱(10)의 높이만큼 하강시켜 걸림턱(10)으로부터 상부금형(4, 5)이 이탈되도록 한다.When the molding of a large container such as the septic tank 30 is made, the shanghai conveying apparatus (A) is lowered by the height of the locking jaw 10 as shown in FIG. Be sure to
걸림턱(10)에서 상부금형(4, 5)이 이탈되는 동시에 밀림방지장치(C)의 유압실린더(20)(20')를 구동시켜 안내홈(19)으로 밀림방지대(18)를 상승시켜서 밀림방지홈(17)에서 밀림방지대(18)가 분리되도록 한다.At the same time as the upper molds 4 and 5 are separated from the locking jaw 10, the hydraulic cylinders 20 and 20 ′ of the anti-rolling device C are driven to raise the chucks 18 into the guide grooves 19. To prevent the jungle prevention 18 from the jungle prevention groove (17).
그러면 결합장치(B)의 유압실린더(24)(24')를 구동시켜 상부금형(4, 5)을 양측으로 분리시킬 때 안내레일(25)에 의하여 양측으로 안정되게 분리된다.Then, the hydraulic cylinders 24 and 24 ′ of the coupling device B are driven to separate the upper molds 4 and 5 to both sides, thereby being stably separated to both sides by the guide rails 25.
상부금형(4, 5)이 분리되면서 정화조(30)의 탈형이 이루어지며 탈형된 정화조는 하부금형(3)으로 이동되어진다.As the upper molds 4 and 5 are separated, the septic tank 30 is demolded, and the demolded septic tank is moved to the lower mold 3.
이때 도 4 에서와 같이 와이어(15) 선단의 고리(15')를 돌출대(13)의 구멍(13')에 걸어 놓고 상하이송장치(A)에 의하여 하부금형(3)을 하측으로 이송시킨다.At this time, the hook 15 'at the tip of the wire 15 is hung on the hole 13' of the protrusion 13, and the lower mold 3 is transferred downward by the shank conveying device A. .
그러면 도 5 에서와 같이 와이어(15)에 의하여 링(12)이 정화조(30)를 그대로 가지고 있게 되므로 일측에서 지게차를 이용하여 정화조(30)을 분리하게 된다.Then, as shown in FIG. 5, since the ring 12 has the septic tank 30 as it is by the wire 15, the septic tank 30 is separated by using a forklift from one side.
정화조(30)의 성형이 완료되면 결합장치(B)의 유압실린더(24)(24')를 구동시켜 안내레일(25)의 안내를 받고 상부금형(4, 5)이 다시 만나서 결합되도록 하는 것이다.When the molding of the septic tank 30 is completed, the hydraulic cylinders 24 and 24 'of the coupling device B are guided to guide the guide rails 25, and the upper molds 4 and 5 meet again to be coupled. .
이때 결합돌기(22)는 상부금형(4, 5)이 중심홈(23)에 의하여 결합되면서 정확하게 중앙에 결합되도록 하는 것이다.At this time, the coupling protrusion 22 is to be coupled to the center while the upper mold (4, 5) is coupled by the center groove (23).
따라서 성형장치(1)에 의하여 성형되는 정화조(30)나 대형 용기는 넓은면의 양측면을 가로돌기(32)와 세로돌기(31)를 성형하고 좁은면의 양측면을 가로돌기(32)만 성형되도록 하여 토압에 효과적으로 견딜 수 있는 제품을 제공하는 것이다.Therefore, the septic tank 30 or the large container formed by the molding apparatus 1 forms the horizontal protrusions 32 and the vertical protrusions 31 on both sides of the wide side, and only the horizontal protrusions 32 on both sides of the narrow side. It is to provide a product that can effectively withstand earth pressure.
본 발명은 일체형 정화조나 대형의 용기 등을 한번에 일체형으로 성형할 수 있는 성형장치를 제공하는 것이다.The present invention provides a molding apparatus capable of integrally molding an integrated septic tank or a large container.
본 발명은 하측의 걸림홈의 외측에 형성된 걸림턱에 상부금형의 하측이 사면에서 걸리도록 하고 상측은 밀림방지장치에 의하여 성형시 발생되는 압력에 대응하여 밀림현상을 방지하여 2.500톤의 압력에도 정확한 제품의 성형이 가능하도록 하는 것이다.According to the present invention, the lower side of the upper mold is caught from the slope by the locking jaw formed on the outer side of the locking groove on the lower side, and the upper side prevents the phenomena corresponding to the pressure generated during the molding by the anti-slip device, so that the pressure is accurate even at a pressure of 2.500 tons. It is to enable the molding of the product.
본 발명은 제품의 성형후 탈형되면서 와이어와 걸림홈에 위치하는 링에 의하여 상하부금형에서 탈형이 되어 대형제품을 쉽게 이탈시킬 수 있도록 하는 것이다.The present invention is to be demolded from the upper and lower molds by the ring located in the wire and the locking groove while demolding after the molding of the product so that the large product can be easily separated.
본 발명은 상부금형이 벌어진후 성형하기 위하여 결합될때 결합돌기에 의하여 정확한 중심에 결합이 이루어 지도록 하는것이다.The present invention is to ensure that the coupling is made in the correct center by the coupling protrusion when the upper mold is opened to form after forming.
본 발명은 일체형의 정화조 또는 용기를 한번에 성형할 수 있어서 성형원가를 절감하고 설치후 내용물이 지하에 유출되는환경오염의 원인을 해결하는 것이다.The present invention can be molded at one time the septic tank or container to reduce the molding cost and solve the cause of environmental pollution that the contents are leaked underground after installation.
