In the present embodiment, the cam mechanism includes a second roller 9 fixedly connected below the first swing arm 8, and a cam guide (not shown in the figure) for driving the first swing arm 8 to swing through the second roller 9. The first swing arm 8 is driven to swing around the axis line direction of the second shaft 7 by the rolling of the second roller 9 on the cam guide.
Referring to fig. 5-6, in the present embodiment, the first shaft 1 and the second shaft 7 each extend in a vertical direction. The first driving mechanism further comprises a second connecting rod 10, one end of which is fixedly arranged on the second shaft 7, a third connecting rod 11 and a fourth connecting rod 12, two ends of which are respectively and rotatably connected to the left die carrier 3 and the other end of the second connecting rod 10, and two ends of which are respectively and rotatably connected to the right die carrier 4 and the other end of the second connecting rod 10. When the mold is opened, the second connecting rod 10 rotates clockwise around the axis of the second shaft 7, the left mold frame 3 is driven to rotate clockwise around the axis of the first shaft 1 through the third connecting rod 11, and the right mold frame 4 is driven to rotate anticlockwise around the axis of the first shaft 1 through the fourth connecting rod 12; when the die is closed, the second connecting rod 10 rotates anticlockwise around the axis of the second shaft 7, the left die carrier 3 is driven to rotate anticlockwise around the axis of the first shaft 1 through the third connecting rod 11, and the right die carrier 4 is driven to rotate clockwise around the axis of the first shaft 1 through the fourth connecting rod 12.
The linkage mechanism comprises a first connecting rod 13, the upper end of the first connecting rod is hinged to the bottom die mold frame 5, the lower end of the first connecting rod 13 can be arranged on the machine frame 2 in a reciprocating mode along the linear direction, the included angle formed by the sliding direction of the lower end of the first connecting rod 13 and the vertical direction is α, wherein the included angle is more than 0 degrees and less than α and less than 180 degrees, and in the embodiment, α =90 degrees.
Referring to fig. 7 to 9, the linkage mechanism further includes a first roller 14 provided on one of the first link 13 and the first swing arm 8, and a cam groove 15 provided on the other for cooperating with the first roller 14 to move. Specifically, the cam groove 15 is provided with a cam curve 16, and the first swing arm 8 and the first link 13 are linked by the movement of the roller in the cam curve 16.
In the present embodiment, the first link 13 includes a link body 131, a link base 132 hinged to a lower end of the link body 131, and a slider 133 provided on the link base 132, the above-mentioned link mechanism further includes a linear guide 17 provided on the frame 2, and the slider 133 is provided on the linear guide 17 so as to be slidable back and forth in a longitudinal extension direction of the linear guide 17, and since α =90 °, the linear guide 17 extends in a horizontal direction.

In fig. 9, the cam groove 15 is provided on the link base 132, the first roller 14 is provided on the first swing arm 8, and the first swing arm 8 drives the first roller 14 to swing back and forth around the axial line direction of the second shaft 7, and drives the cam groove 15 to reciprocate in the horizontal plane in the direction parallel to the linear guide 17. Since the cam groove 15 is provided on the first link 13 or the first swing arm 8 so as to be capable of reciprocating (reciprocating swing or reciprocating linear motion) in the horizontal plane without being displaced in the vertical direction, the cam groove 15 is a plane cam integrally with the first swing arm 8 or the link base 132. The structure of adopting the plane cam not only has the advantages of simple processing and high assembly precision, but also has the advantages of high running precision and low noise.
The upper end of the connecting rod body 131 is hinged to the bottom die carrier 5 through a first hinge point 18, and the lower end of the connecting rod body 131 is hinged to the connecting rod seat 132 through a second hinge point 19.

That is, two ends of the connecting rod body 131 respectively reciprocate along two mutually perpendicular straight lines to realize the driving of the bottom die by the first swing arm 8.
The wedge-shaped snap rings arranged in the left mold frame 3 and the right mold frame 4 need to completely enter the wedge-shaped ring groove of the bottom mold during mold closing, and need to completely separate from the wedge-shaped ring groove of the bottom mold during mold opening. Therefore, the movement of the bottom mold must be stopped when the mold opening and closing frame is in the initial stage of opening and in the vicinity of the closing stage. By adjusting the cam curve 16 of the cam groove 15, the linkage mechanism can ensure that the first connecting rod 13 is not linked to act when the mold opening and closing frame is in the initial opening stage and the closing stage, so that the first connecting rod 13 stops acting; that is, when the bottom mold is located at the highest point, the bottom mold can be temporarily in a self-locking state, and at this time, even if the first rollers 14 move in the cam grooves 15, the bottom mold is not driven to move up and down. Because the lower end of the first connecting rod 13 only makes a linear motion, the design of the cam curve 16 is simple, a redundant segment can be easily reserved at one end of the cam curve, and when the first roller 14 moves in the redundant segment, the bottom die is in a self-locking state and is not influenced by linkage.
When the first swing arm 8 swings in the forward direction: the upper end of the first link 13 is lowered by the cam groove 15 and the first roller 14; the first driving mechanism synchronously drives the die frame to open and close; when the first swing arm 8 swings reversely: the upper end of a first connecting rod 13 is driven to rise through a cam groove 15 and a first roller 14, and the mold opening and closing mold frame is synchronously driven to close and close the mold through a first driving mechanism; the first swing arm 8 is used for driving the first connecting rod 13 to stop acting through the cam groove 15 when the mold opening and closing frame is in an opening initial stage and is close to a closing stage.
Referring to fig. 3-4, during mold opening, under the driving of the cam groove 15 and the first roller 14, the lower end of the connecting rod body 131 slides in a direction away from the upper end thereof, keeps inclining, and the included angle between the connecting rod body 131 and the vertical direction gradually increases; when the mold is closed, the lower end of the link body 131 slides in a direction close to the upper end thereof under the drive of the cam groove 15 and the first roller 14, and after the mold is closed in place, the link body 131 extends in the vertical direction.
The device of the utility model is simple in structure, stable performance can satisfy high-speed moving requirement.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
