As shown in FIG. 3, in this embodiment, the two sealing mold halves 22 of each sealing die 21 are connected by a linkage mechanism, and the sealing mold half 22 near the outer side of the swinging seat 1 is driven by the sealing die driving cylinder 25 to pass. The linkage mechanism drives the other sealing mold half 22 to move synchronously in the opposite direction. SP, the two sealing mold halves 22 can be synchronized to each other or the same by the linkage mechanism The steps are separated from each other to realize the locking and opening of the sealing die 21, and the two sealing die halves 22 are linked by the linkage mechanism, which is easy to ensure the accuracy of opening and closing of the sealing die 21, and is convenient for debugging.

In this embodiment, the linkage mechanism includes two sets of swing rod groups, and the two sets of swing rod groups are symmetrically arranged at both ends of the seal mold half 22. Each set of swing levers includes an intermediate swing lever 31, a first swing link 32, and a second swing link 33. In each swinging rod group, the middle portion of the intermediate swinging rod 31 is hinged to the rotating base 1, one end of the intermediate swinging rod 31 is hinged to one end of the first swinging rod 32, and the other end of the intermediate swinging rod 31 is close to the second swinging rod 33. The sealing mold halves 22 on the outer side of the slewing seat 1 are connected (wherein one end of the second swing rod 33 is hinged to the intermediate swing rod 31, and the other end of the second swing rod 33 is hinged to the sealing mold half 22 near the outer side of the slewing seat 1), The other end of a swing rod 32 is hinged to the other seal mold half 22. Of course, in other embodiments, in order to realize that the two sealing mold halves 22 are close to each other or synchronized away from each other, the linkage mechanism may also be a combination of other forms of multiple rods.

Since the movement locus of the end portion of the intermediate swing rod 31 is an arc when the intermediate swing lever 31 is swung, and the movement locus of the seal mold half 22 is a straight line, the seal half mold can be closed by articulating the second swing rod 33 therebetween. The linear movement of 22 is smoothly converted into the arc swing of the intermediate swing lever 31.

As shown in Fig. 2 and Fig. 3, in the present embodiment, the two sealing mold halves 22 of the sealing die 21 are mounted on the rail pair 8 which is arranged along the expansion and contraction direction of the sealing die driving cylinder 25. A guide rail of the rail pair 8 corresponding to the sealing mold half 22 near the outer side of the swing base 1 is mounted on the lock template of the main mold half 61.

As shown in FIG. 2, in the present embodiment, the main mold includes two main mold halves 61 which are oppositely mounted on the swivel base 1 and movable on the swivel mount 1, and are used to drive the two main mold halves 61. Opening and closing of the clamping mechanism.

The clamping mechanism includes a main mold driving cylinder 62 and two sets of link groups connected to the driving end of the main mold driving cylinder 62. The telescopic direction of the main mold driving cylinder 62 is perpendicular to the opening and closing direction of the main mold half 61, and the main body in this embodiment The die drive cylinder 62 is a servo cylinder or a servo electric cylinder or a servo hydraulic cylinder. The two sets of link sets are symmetrically arranged along the telescopic direction of the main die drive cylinder 62, and each set of link sets is connected to a main mold half 61. Since the two sets of link sets are symmetrically arranged along the telescopic direction of the main die drive cylinder 62, when the main mode drive cylinder 62 is operated, the action trajectories of the two sets of link sets are also symmetrical, thereby driving the two main mold halves 61 to be close to each other or Synchronize away from each other to achieve clamping and mold opening.

In this embodiment, each set of link sets includes a third swing link 64 and a link 65. In each link set, a middle portion of the third swing link 64 is hinged to the swing seat 1, and one end of the third swing link 64 is connected. One end of the rod 65 is hinged, and the other end of the third swing rod 64 is connected to the corresponding main mold half 61 and can drive the main mold half 61 to move along the slide rod 12; the other end of the link 65 is hinged to the drive of the main mold drive cylinder 62. At the end (i.e., the telescopic rod 63), the driving end of the main mold driving cylinder 62 is provided with a carrier block for articulating with the link 65. The power of the main mold driving cylinder 62 is transmitted to the main mold half 61 by the cooperation of the third swing lever 64 and the link 65.
