The reinforcing rib plate 21 can improve the structural strength of the connection between the lifting rod 11 and the contact plate 12, making the installation of the upper template 6 and the lower template 5 more stable.

[0034] The limiting rods 13 are eight in number and are fixedly installed on the side walls of eight abutment plates 12. The upper and lower limiting rods 13 are movably inserted into the upper connecting seat 4 and the base 1, respectively, and the ends of the upper and lower limiting rods 13 are movably inserted into the slots 14 opened on the upper connecting seat 4 and the base 1, respectively. The upper connecting seat 4 is movably provided with a limiting frame 22, and the end of the limiting frame 22 is locked in the slot 23 opened on the upper limiting rod 13. The front side wall of the upper connecting seat 4 is threadedly inserted with a threaded rotating rod 24, and the rear end of the threaded rotating rod 24 is rotatably connected to the limiting frame 22 through a bearing. The rotation of the threaded rotating rod 24 can realize the movement of the limiting frame 22 in the upper connecting seat 4. By locking the limiting frame 22 in the slot 23, the force distribution during the installation of the upper template 6 can be realized, and the stability of the upper template 6 in the installation state can be improved.

[0035] The threaded rod 15 consists of eight rods, which are inserted into the lifting rod 11 by means of threaded rotation. The ends of the threaded rods 15 on the upper and lower sides are respectively inserted into the upper connecting seat 4 and the base 1 by means of bearings. The ends of the threaded rods 15 are connected to the drive rod 7 by means of bevel gear pair. The support frame 2 is provided with a synchronous adjustment mechanism 16 connected to the drive rod 7.

[0036] The synchronization adjustment mechanism 16 includes:

[0037] Movable block 16-1 is fixedly installed on the left side of the rear side wall of the upper connecting seat 4 and is movably installed in the first movable slot 17 opened on the left side of the front side wall of the support frame 2. Movable block 18 is fixedly installed on the right side of the rear side wall of the upper connecting seat 4 and is movably installed in the second movable slot 19 opened on the right side of the front side wall of the support frame 2. Movable block 18 can provide auxiliary guidance for the movement of the upper connecting seat 4, so that the movement of the upper connecting block can have high stability.

[0038] The worm 16-2 is rotatably inserted into the first movable block 16-1 via a bearing. The rear end of the upper left drive rod 7 is rotatably inserted into the first movable block 16-1 via a bearing and a worm wheel 16-3 is fixedly sleeved thereon.

The drive rods 7 drive the threaded rod 15 to rotate through the bevel gear pair, causing the lifting rods 11 on the upper and lower sides to move synchronously in opposite directions. The lifting rods 11 drive the contact plate 12 to move. At this time, the lower contact plate 12 moves upward to disengage from the lower template 5, and the upper contact plate 12 drives the upper template 6 to move downward and disengage from the upper connecting seat 4. At the same time, one end of the limiting rod 13 disengages from the slot 14. After that, the upper template 6 and the lower template 5 can be replaced.

[0042] By cooperating with the drive rod 7, the synchronization rod 8, the adjustment rod 9, the fixed cylinder 10, the lifting rod 11, the contact plate 12, the limit rod 13 and the threaded rod 15, the simultaneous disassembly of the lower template 5 or the upper template 6 at various installation positions can be achieved, thus enabling the equipment to quickly change molds.

[0043] With the cooperation of the synchronous adjustment mechanism 16, the lower template 5 and the upper template 6 can be disassembled and assembled synchronously, thereby further improving the mold changing efficiency of the equipment.

[0044] By locking the limit bracket 22 in the slot 23, the stress distribution during the installation of the upper template 6 can be achieved, thereby improving the stability of the upper template 6 in the installation state.

[0045] The reinforcing rib 21 can improve the structural strength of the connection between the lifting rod 11 and the contact plate 12, making the installation of the upper template 6 and the lower template 5 more stable.

[0046] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
