상기와 같은 목적을 달성하기 위한 본 발명은, 세그먼트의 바닥면 성형을 이루는 하부지지체를 구비하는 세그먼트 몰드에 있어서, 상기 하부지지체의 양측 상부면에 상기 하부지지체의 중심축 방향으로 만곡된 연결부재가 고정되고, 상기 연결부재에는, 상기 세그먼트 몰드의 측면을 개폐시키는 조인트커버가 힌지축에 의하여 회동가능하도록 결합되어 이루어진 것을 특징으로 한다.The present invention for achieving the above object, in the segment mold having a lower support forming the bottom surface of the segment, the connection member curved in the direction of the central axis of the lower support on both upper surfaces of the lower support The joint member is fixed to the connection member, and the joint cover for opening and closing the side surface of the segment mold is rotatably coupled by a hinge axis.

보다 바람직하게, 상기 양측의 조인트커버는 각각 상기 세그먼트 몰드의 측 면을 폐쇄한 상태에서 자동으로 개방되지 않도록 그 무게중심이 형성되되, 좌측의 조인트커버의 무게중심은 상기 힌지축의 수직선상 우측에 형성되고, 우측의 조인트커버의 무게중심은 상기 힌지축의 수직선상 좌측에 형성되는 것을 특징으로 한다.More preferably, each of the joint covers on both sides is formed with its center of gravity so as not to open automatically in a state in which the side surfaces of the segment mold are closed, and the center of gravity of the joint cover on the left side is formed on the right side on the vertical line of the hinge axis. The center of gravity of the joint cover on the right side is formed on the left side on the vertical line of the hinge axis.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 일실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일실시예에 의한 세그먼트 몰드의 정면도, 도 3은 본 발명의 일실시예에 의한 세그먼트 몰드의 조인트커버 연결구조를 도시한 도면이다.2 is a front view of a segment mold according to an embodiment of the present invention, Figure 3 is a view showing a joint cover connection structure of the segment mold according to an embodiment of the present invention.

본 발명의 조인트커버 일체형 세그먼트 몰드의 구조를 간단하게 설명하면 도 2에 도시된 바와 같이, 하부지지체(130)의 양측 상부면에 각각 연결부재(220)가 고정되고, 이 연결부재(220)에 조인트커버가 힌지축(230)에 의하여 회동가능하도록 결합되는 구조이다.Briefly describing the structure of the joint cover integrated segment mold of the present invention, as shown in Figure 2, the connecting member 220 is fixed to each upper surface of both sides of the lower support 130, the connection member 220 The joint cover is structured to be rotatable by the hinge shaft 230.

상기 연결부재(220)는 힌지축(230)에 의하여 조인트커버(110)가 회동가능하도록 지지하는 구성요소로서, 세그먼트 몰드(10)의 측면을 개폐시키는 조인트커버(110)의 회동범위를 간섭하지 않게 하기 위해서 연결부재(220)의 상부측는 하부지지체(130)의 중심축 방향으로 만곡되어 형성된다. 그리고 연결부재(220)가 하부지지체(130)에 고정되는 부분에 가까울수록 폭을 더 넓게 형성하여, 내구성이 강화되고 조인트커버(110)를 지지함에 있어 지지력이 더욱 보강되도록 형성된다.The connecting member 220 is a component that supports the joint cover 110 to be rotatable by the hinge shaft 230 and does not interfere with the rotation range of the joint cover 110 that opens and closes the side surface of the segment mold 10. In order to prevent the upper side of the connecting member 220 is formed to be curved in the direction of the central axis of the lower support 130. In addition, the closer the connection member 220 is to the portion fixed to the lower support 130, the wider the width is formed, so that the durability is strengthened and the support force is further reinforced in supporting the joint cover 110.

이러한 연결부재(220)를 하부지지체(130)에 고정하는 방법은 통상적인 용접법에 의해 고정하거나 연결부재(220)에 볼트를 관통시켜 하부지지체(130)에 고정하 는 방법 등이 사용될 수 있으며, 이 외에도 연결부재(220)를 하부지지체(130)에 고정하는 방법이라면 모두 사용 가능하므로 특정방법으로 한정하지 않는다.The method of fixing the connection member 220 to the lower support 130 may be fixed by a conventional welding method or a method of fixing to the lower support 130 by passing a bolt through the connection member 220, In addition to this, if the method of fixing the connecting member 220 to the lower support 130 can be used because it is not limited to a specific method.

한편, 연결부재(220)의 말단부에는 관통홀이 형성되어, 이 홀에 힌지축(230)을 관통시켜서 조인트커버(110)와 연결되도록 한다.On the other hand, a through hole is formed in the distal end of the connecting member 220, so that the hinge shaft 230 passes through the hole to be connected to the joint cover 110.

힌지축(230)에 의하여 연결부재(220)에 형성된 관통홀에 연결되는 조인트커버(110)는 세그먼트 몰드(10)의 측면을 개폐시키는 구성요소로서, 상기 연결부재(220)의 만곡된 부분이 조인트커버(110)의 내측에 위치할 수 있도록 조인트커버(110)는 양측면이 폐쇄된 "ㄷ"자형의 프레임으로 형성된다. 한편, 조인트커버(110)의 양측면에는 연결부재(220)에 형성된 관통홀과 함께 힌지축(230)이 통과될 수 있도록 관통홀이 형성된다.The joint cover 110 connected to the through hole formed in the connecting member 220 by the hinge shaft 230 is a component that opens and closes the side surface of the segment mold 10, and the curved portion of the connecting member 220 is formed. The joint cover 110 is formed in a frame of a "c" shape in which both sides of the joint cover 110 are closed so as to be located inside the joint cover 110. On the other hand, through holes are formed on both side surfaces of the joint cover 110 so that the hinge shaft 230 can pass along with the through holes formed in the connecting member 220.

상기 연결부재(220)와 상기 조인트커버(110)는 각각의 구성요소에 형성된 관통홀에 힌지축(230)을 관통시켜서 연결되는 구조로서, 연결부재(220)에 연결된 조인트커버(110)가 회동하여 세그먼트 몰드(10)의 측면을 개폐한다는 것이 본 발명의 요지이므로 연결부재(220)의 갯수와 조인트커버(110)의 형상은 제작하기 위한 세그먼트의 형상에 따라서 적적하게 변경하여 사용가능함은 물론이다.The connecting member 220 and the joint cover 110 are connected to each other by penetrating the hinge shaft 230 through the through holes formed in the respective components, and the joint cover 110 connected to the connecting member 220 is rotated. Since opening and closing the side surface of the segment mold 10 is the gist of the present invention, the number of connecting members 220 and the shape of the joint cover 110 can be used appropriately changed according to the shape of the segment to be manufactured. .

한편, 상기 양측의 조인트커버(110)는 각각 상기 세그먼트 몰드(10)의 측면을 폐쇄한 상태에서 자동으로 개방되지 않도록 그 무게중심이 형성되되, 좌측의 조인트커버의 무게중심은 상기 힌지축(230)의 수직선상 우측에 형성되고, 우측의 조인트커버의 무게중심은 상기 힌지축(230)의 수직선상 좌측에 형성된다.On the other hand, the joint cover 110 of both sides is formed with its center of gravity so as not to open automatically in a state in which the side of the segment mold 10 is closed, respectively, the center of gravity of the left joint cover is the hinge axis 230 The center of gravity of the joint cover on the right side is formed on the left side on the vertical line of the hinge shaft 230.

좌측의 조인트커버에 대하여 다시말하면, 세그먼트 몰드(10)의 측면을 폐쇄 한 상태에서 좌측의 조인트커버의 무게중심이 힌지축(230)의 수직선상 우측에 있도록 하여 조인트커버(110)의 자중에 의해서 자동으로 개방되지 않고, 폐쇄된 상태가 유지되므로 세그먼트 몰드(10)에 재료투입을 할 수 있는 상태가 되고, 세그먼트를 탈형시킬 때에는 세그먼트 탈형과 동시에 뒤로 젖혀져서 무게중심이 힌지축(230)의 수직선상 좌측에 있게 되므로 별도의 작업 없이 세그먼트의 탈형을 쉽게 할 수 있다. In other words, with respect to the joint cover on the left side, the center of gravity of the joint cover on the left side is closed on the vertical line of the hinge axis 230 in the state where the side face of the segment mold 10 is closed. Since it is not automatically opened, the closed state is maintained, so that the material can be injected into the segment mold 10, and when the segment is demolded, the segment center is rolled back at the same time as the segment demold, so that the center of gravity of the hinge axis 230 is vertical. Since it is on the left side of the ship, it is easy to demote the segment without any work.

우측의 조인트커버에 대한 설명은 상술한 좌측의 조인트커버에 대한 설명으로 자명하게 알 수 있으므로 생략한다.Description of the joint cover on the right side will be omitted because it will be apparent to the description of the joint cover on the left side described above.

이상 설명한 본 발명은 그 기술적 사상 또는 주요한 특징으로부터 벗어남이 없이 다른 여러 가지 형태로 실시될 수 있다. 따라서, 상기 실시예는 모든 점에서 단순한 예시에 지나지 않으며 한정적으로 해석되어서는 안 된다.The present invention described above can be embodied in many other forms without departing from the spirit or main features thereof. Therefore, the above embodiments are merely examples in all respects and should not be interpreted limitedly.

상기와 같이 구성된 본 발명의 조인트커버 일체형 세그먼트 몰드에 의하면, 세그먼트 탈형시 조인트커버가 자동으로 개방되도록 하여 별도의 공구나 인력을 필요로 하지 않는다.According to the joint cover integrated segment mold of the present invention configured as described above, the joint cover is automatically opened when the segment is demolded, so that no separate tool or manpower is required.

또한, 세그먼트 몰드의 측면을 개폐시키는 시간이 단축되므로 대량생산에 적합하다.In addition, since the time for opening and closing the side face of the segment mold is shortened, it is suitable for mass production.
