Through this setting, the limiting member is used to limit the rotational movement of the auxiliary guide rail 2 around the first axis line 4 towards the main guide rail 1, so as to prevent the auxiliary guide rail 2 from hitting the main guide rail 1 during the rotation process.
[0033] SeeFigure 5 As shown, in this embodiment, the limiting member is a limiting shaft 6 protruding downward at the outlet end of the auxiliary guide rail 2, and the tension spring 5 is used to provide an elastic restoring force for driving the limiting shaft 6 to abut against the inner peripheral portion of the connecting seat 3 (refer to Figures 1 - 2 the main guide rail 1 in, the circumference is the outer side, and the center of the circle is the inner side).
[0034] See Figure 4 As shown, a limiting groove 31 for the limiting shaft 6 to be caught in is provided on the inner peripheral portion of the connecting seat 3, and the limiting groove 31 and the limiting shaft 6 are respectively arranged in the vertical direction.
[0035] See Figure 4 As shown, a mounting shaft 7 is provided on the connecting seat 3, and the two ends of the tension spring 5 are respectively connected to the mounting shaft 7 and the limiting shaft 6. Through this setting, when the outlet end of the auxiliary guide rail 2 rotates away from the main guide rail 1, it can be reset by the tension spring 5.

[0037] See Figures 3 - 5 As shown, a first hole 32 is provided on the connecting seat 3, a second hole 21 is provided on the auxiliary guide rail 2, the axis lines of the first hole 32 and the second hole 21 are both the first axis line 4, and the opening and closing locking guide rail further includes a rotating shaft 8 passing through the first hole 32 and the second hole 21. Through this setting, the auxiliary guide rail 2 can rotate relative to the connecting seat 3 around the first axis line 4.
[0038] Among the connecting seat 3 and the auxiliary guide rail 2: One of them is fixedly connected to the rotating shaft 8, and a bearing 9 sleeved on the rotating shaft 8 is provided in the other one, and among them, the bearing 9 is fixedly sleeved on the rotating shaft 8.
[0039] In this embodiment, the connecting seat 3 is fixedly connected to the rotating shaft 8 through a first gasket 10 and a first screw 11 provided at the bottom of the rotating shaft 8. A step surface 81 is provided on the upper side of the rotating shaft 8, the lower end surface of the bearing 9 abuts against the step surface 81, and the bearing 9 is fixed on the rotating shaft 8 through a second gasket 12 and a second screw 13 provided at the top of the rotating shaft 8.
[0040] See Figure 1 As shown, a guiding side surface 22 is provided at the inlet end of the above-mentioned auxiliary guide rail 2, this guiding side surface 22 faces the main guide rail 1, and the distance between the guiding side surface 22 and the main guide rail 1 gradually decreases along the entering direction of the opening and closing roller. Through this setting, it can play a guiding role in the movement of the opening and closing roller entering between the two.
[0041] By setting the auxiliary guide rail 2 of the flexible connection, when the mold clamping mechanism of the mold base assembly is locked, the opening and closing roller enters the opening and closing guide rail. Under the action of the auxiliary guide rail 2, one side of the opening and closing roller is in close contact with the guide surface of the main guide rail 1, and the other side is in close contact with the guide surface of the auxiliary guide rail 2, realizing precise limitation of the running track of the opening and closing roller in the locking section. When the mold base assembly has abnormal mold clamping due to reasons such as clamping the container blank, the opening and closing roller can also enter through the guiding side surface 22 of the auxiliary guide rail 2 and push the auxiliary guide rail 2 to rotate around the first axis line 4 under the limitation of the tension spring 5. When the opening and closing roller rolls out of the auxiliary guide rail 2, under the action of the tension spring 5, the auxiliary guide rail 2 rotates and resets until the limiting shaft 6 on it fits with the limiting groove 31 on the connecting seat 3, and the reset of the auxiliary guide rail 2 is completed.
