Description

Technical Field

[0001] The utility model belongs to the technical field of bottle blank production equipment, and specifically relates to an alignment rod structure, a core blowing plate component and a mold post-processing device. Background Art

[0002] During the hoisting process of the injection mold, it is necessary to install the alignment rod on the core blowing plate, and use the alignment rod to align the core blowing plate with the take-out plate.

[0003] Normally, after the lifting is completed, the alignment rod needs to be removed from the core blowing plate. However, it is difficult to remove the alignment rod from the core blowing plate. Therefore, for the sake of convenience, most preform manufacturers do not remove the alignment rod after completing the alignment process of the core blowing plate and the take-out plate. As a result, there are the following risks:

[0004] 1. In the long billet mold, the center distance between the core blowing plate and the take-out plate is long. Accordingly, a longer alignment rod is required to align the core blowing plate with the take-out plate. When the core blowing plate is flipped, the longer alignment rod has the risk of colliding with the machine, which may cause damage to the alignment rod.

[0005] 2. The alignment rod may block the electronic eye and affect its normal operation.

[0006] 3. In a compact preform mold, when the preform is post-processed, there is a risk that the alignment rod will rub against the outer edge of the removal sleeve, which may scratch the removal sleeve and cause damage to the removal sleeve. Utility Model Content

[0036] Based on the above disclosed alignment rod structure, such as Figure 6 As shown, this embodiment also discloses a core blowing plate assembly, including a core blowing plate 5, on which the alignment rod structure is installed. A picker 51 and a core blowing plate 52 are also installed on the core blowing plate 5.

[0037] In this embodiment, one end of the locating pin 1 has a locating pin installation protrusion 14; the alignment rod connecting rod 21 cooperates with the locating pin connecting hole 11 from the other end of the locating pin 1; and the blow core plate 5 is provided with a blow core plate groove 53 that matches the locating pin installation protrusion 14.
