Current blown glass molds consist of two semi-cylindrical glass molds joined together, with a cavity machined at the joint. CNC lathes are used to shape the cavity, and the glass mold blank is clamped onto the machining table using a vise or a contour jig. The vise method has low clamping accuracy and efficiency, while the contour jig method suffers from poor jig versatility and high cost. Utility Model Content

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0019] Example: A clamping mechanism for processing the inner cavity of a glass bottle mold includes a base plate 1, a fixed clamping plate 4 disposed at one end of the base plate 1, a movable clamping plate 2 disposed at the other end of the base plate 1, a top limiting block 5 disposed at the top of the movable clamping plate 2 and the fixed clamping plate 4, and a movable chuck assembly 6 disposed on the movable clamping plate 2. The movable clamping plate 2 and the fixed clamping plate 4 are disposed opposite to each other. Each of the movable clamping plate 2 and the fixed clamping plate is provided with two lower support positioning assemblies 7. The two lower support positioning assemblies 7 are symmetrically arranged front and back along the axis of the glass bottle mold. The lower support positioning assembly 7 includes a lower support connecting part 71 and a lower support member 70 threadedly connected to the lower support connecting part 71. The connecting thread axis of the lower support connecting part is perpendicular to the length direction inside the glass bottle mold. The movable chuck assembly 6 includes an operating lever 60 that is telescopically locked along the axis of the glass bottle mold and a movable clamping block 61 disposed at the end of the operating lever 60 pointing towards the fixed clamping plate 4.

[0020] The clamping mechanism is adaptable to glass molds 15 of different heights by adjusting the distance between the movable clamping plate 2 and the fixed clamping plate 4, and adaptable to glass molds 15 of different outer diameters by adjusting the extension length and angle of the lower support 70. The clamping mechanism has good versatility; multiple angle support limits facilitate quick and easy clamping; and the movable clamping block 61 facilitates locking the clamped glass mold 15. To reduce maintenance costs, a threaded plate 8 is detachably connected to the movable clamping plate 2. When the threads are damaged, only the threaded plate 8 or the operating lever 60 needs to be replaced. The threaded plate 8 has a threaded through hole 9, and the operating lever 60 is a screw 711. The operating lever 60 is threaded into the threaded through hole 9. The head of the operating lever 60 is rotatably connected to the movable clamping block 61, and the tail end of the operating lever 60 has a transverse rod 10 for easy rotation and adjustment.

[0021] Please see Figure 2The movable clamping plate 2 has a receiving cavity 11 on the side facing the glass bottle mold to accommodate the movable clamping block 61. The movable clamping block 61 has a first position where it is fully retracted into the receiving cavity 11 and a second position where it is partially extended out of the receiving cavity 11. The receiving cavity 11 is used to avoid the movable clamping block 61 when the glass bottle mold is inserted.

[0022] The bottom plate 1 has a left-right extending lower T-shaped groove 3 at its top. The movable clamping plate 2 and the fixed clamping plate 4 are provided with fixing bolts 12, the tail ends of which extend into the lower T-shaped groove 3. The lower T-shaped groove 3 facilitates the adjustment of the position of the movable clamping plate 2 and the fixed clamping plate 4.

[0023] Please see Figure 4 The movable clamping plate 2 and the fixed clamping plate 4 are each provided with two top limiting blocks 5 at their tops. The movable clamping plate 2 and the fixed clamping plate 4 are each provided with an upper T-shaped groove 13 extending forward and backward at their tops. Each top limiting block 5 is provided with an upper limiting bolt, the tail end of which extends into the upper T-shaped groove 13. The position of the top limiting block 5 is adjusted via the upper T-shaped groove 13 to avoid obstructing the processing position of the glass bottle / jar mold.

[0024] Please see Figure 2 The movable clamping plate 2 and the fixed clamping plate 4 are provided with left and right extending light holes 14. The lower support connecting part 71 includes a screw 711, a connecting block 710 disposed at the tail end of the screw 711, and a nut 712 that mates with the screw 711. The screw 711 passes through the light hole 14. The connecting block 710 and the nut 712 are respectively located at both ends of the light hole 14. The connecting block 710 is provided with a screw hole, the axis of which is perpendicular to the screw 711. The lower support member 70 mates with the screw hole, and the head of the lower support member 70 is a ball head. The screw 711 facilitates adjustment of the angle of the lower support member 70, and the threaded lower support member 70 facilitates adjustment of its extension length. The ball head of the lower support member 70 can adapt to the outer peripheral surface of the glass mold 15.

[0025] To improve the stress distribution on the lower support member 70, the angle between the axis of the lower support member 70 and the horizontal plane is 30-40°.

[0026] During operation, the movable clamping block 61 retracts into the receiving cavity 11, and the top limiting block 5 moves out of the clamping space formed between the movable clamping plate 2 and the fixed clamping plate 4. The glass mold 15 is placed into the clamping space formed between the movable clamping plate 2 and the fixed clamping plate 4, and the top limiting block 5 is moved above the glass mold 15. The operating lever 60 is adjusted so that the movable clamping block 61 presses against the end of the glass mold 15.
