[0020] Embodiment 1

[0021] As Figures 1-4 shown, the adjustable opening and closing lock device of the bottle blowing machine side mold frame in the drawing includes a fixed frame 1 and a connecting assembly, characterized in that: a fixed mold frame 2 is vertically and fixedly installed on the top of the fixed frame 1, the outer side of the fixed mold frame 2 is provided with the connecting assembly, the connecting assembly is penetrated through the middle and is connected with the connecting head 8, the end of the connecting head 8 is fixedly connected with the output end of the first hydraulic rod 9, the movable mold frame 10 is movably installed on the opposite side of the fixed mold frame 2 through the connecting assembly, the control assembly is arranged below the connecting assembly, the compression buckle 15 is integrally fixed on the outer side of the movable mold frame 10, the third hydraulic rod 16 is fixedly installed on the fixed frame 1 on the outer side of the compression buckle 15 and is parallel to the horizontal direction, and the end of the third hydraulic rod 16 is fixedly connected with the T-shaped head 17 arranged perpendicularly to the horizontal direction.

[0022] The connecting assembly includes a connecting block 3, a sliding groove 4, a movable rod 5, a connecting frame 6 and a connecting rod 7, the connecting block 3 is fixedly arranged on the outer side of the fixed mold frame 2 and is symmetrically arranged above and below the horizontal central axis of the fixed mold frame 2, the middle of the connecting block 3 is provided with the sliding groove 4, the movable rod 5 arranged perpendicularly is slidably installed in the middle of the sliding groove 4, the end of the movable rod 5 is fixedly connected with the end of the connecting frame 6, and the end of the connecting frame 6 is fixedly connected with the connecting rod 7 on the side opposite to the movable rod 5, and the connecting rod 7 is arranged coincidentally with the center line of the movable rod 5.

[0023] The connecting head 8 is controlled to slide by the first hydraulic rod 9 in extension and retraction, so that the connecting rod 7 in the middle of the connecting head 8 can drive the connecting frame 6 to slide along the sliding groove 4 in the connecting block 3, so that the connecting frame 6 can slide along the sliding groove 4 in the corresponding connecting block 3, so as to cooperate with the third hydraulic rod 16 on the other side to drive the T-shaped head 17 to tension the compression buckle 15, so that the movable mold frame 10 on the outside can be effectively fastened and closed by the two groups of hydraulic rods.

[0024] The control assembly comprises a second hydraulic rod 11, a rack 12, a guide rail 13 and a gear 14. The end of the second hydraulic rod 11 is fixedly provided with the rear end of the rack 12. The outer side of the rack 12 is provided with the guide rail 13. The rack 12 and the guide rail 13 are slidably connected and installed. The side of the rack 12 provided with teeth is provided with the gear 14. The rack 12 and the gear 14 are in meshing connection.

[0025] The movable rod 5 and the rack 12 form a transmission structure through the gear 14. The connecting frame 6 and the connecting block 3 form a rotating structure through the movable rod 5. When the rack 12 slides outward to the outermost point, the last teeth can be separated from the teeth of the gear 14. At this time, the movable mold frame 10 is in a closed state. The connecting frame 6 and the movable mold frame 10 fixedly installed on the connecting frame 6 are controlled to rotate and open. Conversely, when the rack 12 slides forward, the movable mold frame 10 is closed.

The movable mold frame 10 on the outside can be effectively fastened and closed by the two groups of hydraulic rods. Further, the connecting seam is tightly connected to ensure the closing effect and reduce the retention of the gap.

[0027] Working principle: first, the first hydraulic rod 9 drives the connecting head 8 to move forward and backward, so that the connecting rod 7 penetrating the middle of the connecting head 8 drives the connecting frame 6 integrated with the connecting block 3, so that the connecting frame 6 can slide along the sliding groove 4 in the connecting block 3. In this way, the third hydraulic rod 16 on the other side drives the T-shaped head 17 to tension the compression buckle 15, so that the movable mold frame 10 on the outside can be effectively fastened and closed by the two groups of hydraulic rods. Further, the connecting seam is tightly connected to ensure the closing effect and reduce the retention of the gap.

[0028] Then, by controlling the second hydraulic rod 11 below to drive the rack 12 to slide forward and backward along the inside of the guide rail 13, when the rack 12 slides backward, the movable rod 5 is driven to rotate by engaging the transmission gear 14, so as to control the connecting frame 6 and the movable mold frame 10 fixedly installed on the connecting frame 6 to rotate and open, and vice versa, when the rack 12 slides forward, the movable mold frame 10 is closed, when the rack 12 slides forward and outward to the extreme, the external teeth can be separated from the gear 14, at this time, the upper connecting assembly is not affected by the bottom control assembly, and the further closing and fastening operation of the movable mold frame 10 by the first hydraulic rod 9 and the third hydraulic rod 16 can be further realized, and the effect of tight connection is effectively achieved.
