Referring to fig. 1 and 3, in the present embodiment, the first connecting seat 1 is generally cylindrical, and a mounting sleeve 11 for mounting a bottom die is opened at the center of the first connecting seat 1. The first connecting seat 1 is formed by assembling and installing an upper split body 12 and a lower split body 13 through screws, the upper split body 12 and the lower split body 13 positioned below the upper split body are sequentially abutted along a first direction, and the installation sleeve 11 simultaneously penetrates through the upper split body 12 and the lower split body 13 along the first direction.
Above-mentioned but flexible locking mechanism of linear compensation's die block still includes locating between first connecting seat 1 and second connecting seat 2 and be used for adsorbing adsorption component between them, locates the elastic component between first connecting seat 1 and second connecting seat 2, and elastic component's the flexible direction of elasticity is on a parallel with the second direction.
Referring to fig. 5 to 6, the lower surface of the lower sub-body 13 is recessed upward to form a plurality of first slots 131 for receiving the first magnetic members 3 in a one-to-one correspondence, and the upper surface of the second connecting seat 2 is recessed downward to form a plurality of second slots 21 for receiving the second magnetic members 4 in a one-to-one correspondence. The adsorption component comprises a first magnetic part 3 and a second magnetic part 4 which can be adsorbed to each other along a first direction, and the first connecting seat 1 and the second connecting seat 2 are connected through the first magnetic part 3 and the second magnetic part 4 in a magnetic adsorption mode.
In the present embodiment, there are a plurality of the first slots 131 and the second slots 21, respectively, and the first slots and the second slots are aligned one by one along the first direction. The number and arrangement of the first slots 131 can be adjusted as required, and in fig. 5, six first slots 131 are sequentially arranged at intervals along the circumferential direction; correspondingly, there are six second slots 21, which are arranged at intervals along the circumferential direction. The first magnetic member 3 and the first slot 131 may be connected to each other by means of adhesion, nesting, or screw fixation, as shown in fig. 2, and in this embodiment, they are fixedly connected by screws.
Referring to fig. 1 and 5-6, in this embodiment, the second connecting seat 2 is generally cylindrical, the first shaft 5 is radially and convexly arranged on the circumferential surface of the lower split body 13, the connecting member 22 is radially and convexly arranged on the circumferential surface of the second connecting seat 2, one end of the connecting member 22, which is far away from the second connecting seat 2, is protruded upwards, and the second shaft 6 is arranged inside the upwardly protruded end of the connecting member 22. The first shafts 5 and the second shafts 6 are arranged at intervals, and extend coaxially and are respectively parallel to the second direction.
The elastic component is a spring 7 with two ends respectively connected with the first shaft 5 and the second shaft 6. In this embodiment, the two ends of the spring 7 are respectively sleeved on the first shaft 5 and the second shaft 6.
When first connecting seat 1 and second connecting seat 2 adsorb each other, under the effect of external force, first connecting seat 1 can be followed the relative second connecting seat 2 motion of second direction, and spring 7 is stretched or compressed this moment. In this embodiment, the spring 7 is a compression spring, and the compression spring is compressed when the second connecting seat 2 opposite to the first connecting seat 1 moves.
The bottom die and the bottom die support are connected in an adsorption mode through the adsorption component along the first direction and are connected in an elastic mode through the elastic component along the second direction. After the die assembly is carried out, when the bottom die linearly compensates and moves relative to the bottom die support (namely, the first connecting seat 1 moves rightwards relative to the second connecting seat 2 in fig. 4), rigid impact can be reduced and a connecting structure between the first connecting seat 1 and the second connecting seat 2 is prevented from being damaged due to flexible connection between the first connecting seat 1 and the second connecting seat 2; after the bottle blowing is finished, the elastic component can also provide the elastic restoring force for resetting the bottom die and the first connecting seat 1, so that the bottom die is reset to facilitate smooth die opening.

Referring to fig. 4 to 6, the distance of the left and right movement of the first connecting seat 1 relative to the second connecting seat 2 is shorter than the width of the first magnetic member 3 and the second magnetic member 4 along the left and right directions, so that the first magnetic member 3 and the corresponding second magnetic member 4 are prevented from being completely separated when the first connecting seat 1 moves relative to the second connecting seat 2, and the magnetic attraction force between the first magnetic member 3 and the corresponding second magnetic member 4 can be maintained. In this embodiment, the distance of the left and right movement of the first connecting seat 1 relative to the second connecting seat 2 is not more than half of the width of the first magnetic member 3 and the second magnetic member 4 in the left and right direction.

With this arrangement, the distance that the limiting slide 132 slides in the limiting groove 23 from side to side is the distance that the bottom die can move from side to side relative to the bottom die support. In fig. 4, the limiting slide block 132 abuts against the left side of the limiting groove 23 leftwards under the action of the elastic component, a gap is formed between the right side of the limiting slide block 132 and the right side of the limiting groove 23, which is an initial position in fig. 4, and the spring 7 is a compression spring and is in a compressed state. After the die assembly is carried out, under the action of compensation air, the bottom die can carry out linear compensation movement towards the right, and after the right side of the limiting slide block 132 abuts against the right side of the limiting groove 23, the bottom die achieves the maximum linear compensation displacement. In the actual operation process, the displacement of the bottom die can be smaller than the maximum linear compensation displacement.
In this embodiment, there are two sets of limiting assemblies, which are sequentially arranged at intervals along the second direction.
The following specifically explains the working process of this embodiment:
after the die is closed, compensating air is introduced to the left side of the die, so that the left die and the bottom die synchronously move rightwards, the first connecting seat 1 moves rightwards relative to the second connecting seat 2 until the limiting slide block 132 pushes against the right side of the limiting groove 23 rightwards, and at the moment, the spring 7 is compressed;
after the bottle blowing is completed, the introduction of the compensation gas is stopped, and under the action of the spring 7, the first connecting seat 1 moves leftwards relative to the second connecting seat 2 until the limiting slide block 132 abuts against the left side of the limiting groove 23 leftwards, so that the first connecting seat 1 and the bottom die are reset.
