下面结合附图给出本发明较佳实施例，以详细说明本发明的技术方案。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

一种内芯模机构，其包括：移动滑杆 1、滑套 2、挡板 3、芯模外壳 4、小连接板 5、 6、 7和弹簧 8。其中该小连接板 5、 6、 7数量均为两个，并对称的设置在芯模外壳 4的两侧（图 1和图 2中仅显示了一侧的情况）。 An inner core molding mechanism comprising: a moving slider 1, a sliding sleeve 2, a shutter 3, a core mold housing 4, small connecting plates 5, 6, 7 and a spring 8. The small connecting plates 5, 6, and 7 are both in number and symmetrically disposed on both sides of the core mold casing 4 (only one side is shown in Figs. 1 and 2).

其中该内芯外壳 4 由两个匚行的半片组成，两个半片合拢时组成一个空心立方体，内芯外壳 4上端设置一孔供移动滑杆 1穿过。 The inner core casing 4 is composed of two halved half pieces. When the two half pieces are closed, a hollow cube is formed, and a hole is arranged at the upper end of the inner core casing 4 for the moving sliding rod 1 to pass through.

该移动滑杆 1上端位于内芯外壳 4外部的部分上套设有滑套 2。标号 5为连接组合成 Λ形的两个连接小板（以下简称连接小板 5)，并可以绕其顶端旋转进而闭合或打开，其顶端与滑套 2的外壁活动连接，另两端分别与芯模外壳 4两半片的内壁活动连接，并且滑套 2被设置为其上端面可以被卡设在挡板 3处。 A slide sleeve 2 is sleeved on a portion of the upper end of the inner slider 4 at the upper end of the movable slider 1. Numeral 5 is a pair of connecting small plates (hereinafter referred to as connecting small plates 5) which are combined and combined into a dome shape, and can be rotated or closed around the top end thereof, and the top end thereof is movably connected to the outer wall of the sliding sleeve 2, and the other ends are respectively The inner walls of the two halves of the core mold casing 4 are movably connected, and the sliding sleeve 2 is disposed such that its upper end surface can be caught at the baffle 3.

该移动滑杆 1下端位于内芯外壳 4内部，并且在该内芯外壳内部设置有小连接板。其中 6和 7均为两个组合成 V形的两个连接小板（简称为连接小板 6、 7),其可以绕其顶端旋转进而闭合或打开，其下端顶端与移动滑杆 1 由柱销活动连接，另两端分别与芯模外壳 4的两半片的内壁活动连接。在小连接板 6与滑套 2之间的移动滑杆 1上套装有弹簧 8。 The lower end of the moving slider 1 is located inside the inner core casing 4, and a small connecting plate is disposed inside the inner core casing. 6 and 7 are two connecting small plates (referred to as connecting small plates 6, 7) which are combined into a V shape, which can be rotated around the top end to be closed or opened, and the lower end of the lower end and the moving slider 1 are separated by a column. Pin-connected, the other ends are respectively connected to the mandrel The inner walls of the two halves of the outer casing 4 are movably connected. A spring 8 is fitted over the moving slide 1 between the small connecting plate 6 and the sliding sleeve 2.

当该芯模外壳 4在关闭状态下时，移动滑杆 1在凸轮的作用下向上运动，滑套 2被挡板 3卡住，小连接板 6和小连接板 7在移动滑杆 1的带动下向上运动，小连接板 5在力的作用下被打开，芯模外壳 4被打开将套在其上的筒形包材盒变成长方形或正方形，弹簧 8被压缩；移动滑杆 1带动滑套 2—起向下运动，因被压缩的弹簧 8的弹力作用,滑套 2相对滑杆向上运动,使小连接板 5的夹角变小，芯摸外壳 4合拢，随着移动滑杆 1再上升到一定位置，则内芯模外壳 4完全脱离包材盒，为下一歩工位作准备。 When the mandrel housing 4 is in the closed state, the moving slider 1 is moved upward by the cam, the sliding sleeve 2 is caught by the shutter 3, and the small connecting plate 6 and the small connecting plate 7 are driven by the moving slider 1. Moving downwards, the small connecting plate 5 is opened by the force, the core mold casing 4 is opened to turn the cylindrical packaging box sleeved thereon into a rectangular or square shape, the spring 8 is compressed; and the moving sliding rod 1 is driven to slide The sleeve 2 moves downward, and due to the elastic force of the compressed spring 8, the sliding sleeve 2 moves upward relative to the sliding rod, so that the angle of the small connecting plate 5 becomes smaller, and the core touches the outer casing 4 to be closed, with the moving sliding rod 1 When it rises to a certain position, the inner core mold casing 4 is completely separated from the packaging material box, and is prepared for the next work station.

在本发明的实施例中，使用了三个小连接板，其中也可以取消小连接板 7的设置，也可以实现本发明的目的，但是由于加工误差等因素易使芯模外壳张开不平衡或不对称，因此以上述实施例中的设置为较佳。 In the embodiment of the present invention, three small connecting plates are used, wherein the arrangement of the small connecting plates 7 can also be eliminated, and the object of the present invention can also be achieved, but the core mold outer casing is easily unbalanced due to processing errors and the like. Or asymmetry, so the arrangement in the above embodiment is preferred.
