The mold positioning method is more convenient and the structure is simpler, which avoids more mechanical failures and adapts to the fast work process.

[0032] When drilling is required, the locking member 21 is first pulled out of the fixing hole 100, thereby removing the limiting rod 22 from the outer edge of the opening; then, the closing mold of the blow mold 3 is inserted into the mold groove 10 from the opening of the mold groove 10; then, the limiting rod 22 is re-fixed to the outer edge of the opening of the mold groove 10 via the locking member 21; the other end of the limiting rod 22 is pressed against the closing mold side wall of the blow mold 3, and the blow mold 3 can be confined in the mold groove 10 by the limiting rods 22 on both sides; finally, the quick-change fixture for blow mold processing is fixed to the drilling machine for subsequent drilling operations. The avoidance notch is located at the top of the quick-change fixture, which facilitates the drilling machine to perform drilling operations on the top of the closing mold of the blow mold 3.

[0033] Furthermore, the fixing hole 100 includes a first connecting hole 101 and a second connecting hole 102; the first connecting hole 101 is arranged on the outer edge of one side of the opening of the mold groove 10, and the second connecting hole 102 is arranged on the outer edge of the other side of the opening of the mold groove 10, and the limiting member 2 can be detachably connected to the first connecting hole 101 or the second connecting hole 102.

[0034] The first connecting hole 101 cooperates with the limiting piece 2 to fix a limiting rod 22 to the outer edge of one side of the opening of the mold groove 10; the second connecting hole 102 cooperates with another limiting piece 2 to fix the other limiting rod 22 to the outer edge of one side of the opening of the mold groove 10; the other ends of the limiting rods 22 are respectively close to the side walls of the mold closing of the bottle blowing mold 3 to achieve the purpose of fixing the bottle blowing mold 3.

[0035] Furthermore, the first connection hole 101 is located in the middle of the outer edge of the opening of the mold groove 10, and a plurality of second connection holes 102 are provided on the outer edge of the other side of the opening of the mold groove 10. The plurality of second connection holes 102 are spaced apart along the height direction.

[0036] By adopting the above structure, the second connecting hole 102 of the corresponding height can be selected according to the actual height of the blow molding mold 3, thereby improving the adaptability of the quick-change fixture, quickly adapting to the closing of blow molding molds 3 of different specifications, and playing a limiting role in the closing of blow molding molds 3 of different specifications.

[0037] Specifically, the base 1 includes a bottom plate 11, a connecting block 12 and a base connecting member 13;

[0038] The bottom plate 11 is provided with a bottom plate connecting hole 110, and the bottom of the connecting block 12 is provided with a bottom plate connecting hole 120 adapted to the position of the bottom plate connecting hole 110, and the base connecting member 13 passes through the bottom plate connecting hole 110 and is threadedly connected to the bottom plate connecting hole 120; the side wall of the connecting block 12 is provided with an avoidance groove, and the connecting block 12 cooperates with the bottom plate 11 to form a mold groove 10; the fixing holes 100 are arranged on both sides of the avoidance groove.

[0039] The bottom plate 11 serves to connect to the drilling machine. In addition, the top of the bottom plate 11 cooperates with the avoidance groove of the connecting block 12 to form a mold groove 10, and the base connector 13 serves to connect the connecting block 12 and the bottom plate 11.

[0040] Optionally, the escape groove is a semicircular groove. In a specific embodiment of the present invention, the bottle blowing mold includes two closing molds, the bottle blowing mold is cylindrical, and the two closing molds are each semi-cylindrical. This structure facilitates the closing molds to slide into the escape groove during installation, reducing the installation strength of the closing molds and providing a better fit with the bottle blowing mold.

[0041] Specifically, the base 1 further includes a positioning protrusion 14 , which is disposed at the bottom of the base plate 11 and is connected to the outside.

[0042] With the above structure, the positioning protrusion 14 can help workers accurately position the quick-change fixture during the process of assembling the quick-change fixture on the machine tool, ensuring that the quick-change fixture is in the correct position and improving the accuracy of assembly.

[0043] Specifically, the base 1 includes two connecting blocks 12 . The two connecting blocks 12 have the same structure, and both of the connecting blocks 12 cooperate with the bottom plate 11 to form two mold grooves 10 .

[0046] With the above structure, when the bottle blowing mold needs to be limited, the external air source fills the air into the telescopic airbag 104 to expand, so that the airbag is close to the side wall of the bottle blowing mold. When the bottle blowing mold needs to be removed, the external air source extracts the gas to shrink the telescopic airbag 104. With the above structure, the position of the bottle blowing mold is further limited, preventing the bottle blowing mold from being offset during the drilling process, resulting in drilling errors, and improving the drilling accuracy.

[0047] Specifically, a roller groove 105 is provided on the inner wall of the mold groove 10 , and a plurality of roller shafts 106 are provided on the roller groove 105 at intervals along the height direction. Rollers 107 are sleeved on the outer periphery of the roller shafts 106 , and the rollers 107 extend from the roller groove 105 .

[0048] The above structure can reduce the friction between the side wall of the bottle blowing mold and the inner wall of the mold groove 10, making it easier for the bottle blowing mold to slide in, further reducing the difficulty of fixing the bottle blowing mold and improving the efficiency of installation and replacement.

[0049] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
