Embodiment two:
on the basis of the first embodiment, referring to fig. 5 of the specification, in this embodiment, a lateral block 8 is fixedly connected to one side of the mounting ring 71 away from the fixing ring 75; the horizontal block 8 is provided with a horizontal groove 81; two connecting rods 82 are slidably connected in the horizontal groove 81; the other ends of the two connecting rods 82 are fixedly connected with the two fourth blocks 34.
Referring to fig. 8 of the drawings, in this embodiment, two ends of the second rotary telescopic rod 62 are hinged to the second block 32; the second block 32 is provided with an arc-shaped sliding groove 83; an arc block 84 is slidably connected to the arc sliding groove 83; the adjusting rod 64 on the second block 32 is rotatably connected in the arc-shaped block 84; the same fixing piece 85 is rotatably connected between the second rotary telescopic rod 62 and the adjusting rod 64 on the second block 32.
Referring to fig. 10 of the drawings, in the present embodiment, the ejector block 11 is located above the molding die 3, and the ejector block 11 is in contact with the upper surface of the fourth block 34.
According to the invention, the fourth block 34 is in sliding connection with the transverse block 8 through the connecting rod 82, and the fourth block 34 can only transversely slide in the horizontal groove 81, so that after the third block 33 is extracted, the position of the fourth block 34 in the vertical direction is fixed, under the action of the tension of the connecting spring 63, the second block 32 and the first block 31 can only move upwards to be contacted with the fourth block 34, and further the fourth block 34 is always in a horizontal state, but not the second block 32 is fixed, when the fourth block 34 moves downwards, the spliced forming die 3 is downwards sunken, and the situation that the part of the formed packaging buckle, which is attached to the fourth block 34, is downwards sunken is caused;
when the forming die 3 extracts the third block 33, the process that the second block 32 is contacted with the fourth block 34 can be regarded as a process that the second block 32 carries the first block 31 and rotates for a section of circular arc by taking the vertex contacted by the second block 32 and the fourth block 34 as the circle center, so that the arc groove 74 and the arc block 84 are arranged into an arc shape, when the second block 32 rotates upwards, the hinged part of the second block 32 and the second rotary telescopic rod 62 does not influence the movement of the second block 32, and simultaneously, when the second block 32 rotates upwards, the arc block 84 moves in the arc groove 74, the fixing piece 85 enables the bevel gear between the adjusting rod 64 and the second rotary telescopic rod 62 to be always in an engaged state, and the situation that the structure conflict between the adjusting rod 64 and the second rotary telescopic rod 62 and the second block 32 cannot rotate upwards does not occur when the second block 32 rotates upwards;
the push-out block 11 is contacted with the upper surface of the fourth block 34, so that the push-out block 11 is not influenced to be contacted with the forming die 3 when the shape and the size of the forming die 3 are changed, and the effect that the push-out block 11 pushes the formed package to be buckled on the forming die 3 is ensured;
according to the invention, the fourth block 34 is slidably connected to the transverse plate, so that the upper surface of the forming die 3 is always in a horizontal state when the size or shape of the forming die 3 is changed, and therefore, when a steel strip section is formed on the forming die 3, the upper surface is not recessed downwards due to the fact that the fourth block 34 is in a horizontal position, so that the appearance of a packing buckle is not influenced, meanwhile, the two ends of the second rotary telescopic rod 62 are hinged with the two second blocks 32, when the second block 32 moves upwards, the condition that the second block 32 rotates upwards, the adjusting rod 64 collides with the second rotary telescopic rod 62 in structure, and the second block 32 cannot rotate upwards is guaranteed.
