Description

Technical Field

[0001] This utility model relates to the field of blow molding die technology, and in particular to a blow molding die that is easy to process. Background Technology

[0002] In the production of plastic bottles, blow molding dies are used to shape the bottle body. Existing blow molding dies require mold closing, bottom sealing, and air blowing. Typically, the mold is placed vertically when closed, and only a machining hole is reserved at the bottom. The mold is sealed by a machining plug pre-made on the placement table. This process requires high precision, and the probability of the machining plug being properly aligned with the bottom machining hole is low. If the plug cannot be accurately inserted into the machining hole, the mold opening or the machining plug may be damaged, resulting in reduced processing precision and affecting subsequent processing efficiency. Therefore, improvements are needed. Utility Model Content

The first half mold 10 and the second half mold 11 are fitted together to form a mold body. A molding cavity 12 is formed in the mold body. The two ends of the mold body have a first processing port 13 and a second processing port 14, respectively. A first bottom mold 20 adapted to it is provided on the first processing port 13, and a second bottom mold 21 adapted to it is provided on the second processing port 14. When blow molding the bottle, the first half mold 10 and the second half mold 11 are first closed to form the mold body. Then, the plastic solution to be blow molded is pushed into the molding cavity 12. The molding cavity 12 is closed by the first bottom mold 20 and the second bottom mold 21 cooperating with the first processing port 13 and the second processing port 14. Air is blown into the molding cavity 12 by the first bottom mold 20 and / or the second bottom mold 21, thereby achieving precise blow molding of the bottle. Depending on the blow molding requirements of the product, the plastic bottle can be blow molded by blowing air into the molding cavity 12 in one direction by the first bottom mold 20 or by blowing air into the molding cavity 12 in one direction by the second bottom mold 21. A mixed blow molding method can also be used to blow mold the plastic bottle, thereby improving the molding rate and molding effect.

[0019] Both the first half-mold 10 and the second half-mold 11 are provided with an exhaust channel 15, an internal exhaust hole 16, and an external exhaust hole 17.

The internal exhaust hole 16 is connected to the external exhaust hole 17 through the exhaust channel 15. In this embodiment, the internal exhaust hole 16 and the external exhaust hole 17 are connected by an exhaust channel, which facilitates the exhaust of the corresponding gas in the molding cavity 12, thereby improving molding stability.

[0020] Locking grooves 18 are provided on the outer sides of the first half mold 10 and the second half mold 11. After the first half mold 10 and the second half mold 11 are closed, the two locking grooves 18 are engaged to form a locking buckle 19. In this embodiment, locking grooves 18 are provided on both the first half mold 10 and the second half mold 11. The locking grooves 18 on the first half mold 10 and the second half mold 11 cooperate to form the locking buckle 19, which facilitates the stable locking of the first half mold 10 and the second half mold 11 by cooperating with the external locking buckle.

[0021] The diameter of the first processing port 13 is smaller than the diameter of the second processing port 14. In this embodiment, the diameter of the first processing port 13 is smaller than the diameter of the second processing port 14, which facilitates the accommodation of the first bottom mold 20 and the second bottom mold 21 with different specifications.
