And the molding cavity 110 has a positioning area 111 adjacent the first end 810 such that the preform is molded with the blow molded product 20 wrapped around the fitting 30 at the positioning area 111 to prevent the fitting 30 from moving in the direction of the first end 810 (e.g., to prevent the fitting 30 from moving upward if the first end 810 is the upper end of the fitting 30).
This arrangement prevents the fitting member 30 from moving not only in the direction of the second end 820 but also in the direction opposite to that direction, thereby making the fitting member 30 more securely fitted to the blow-molded product 20.
In some embodiments, the other end of the positioning pin 230 is a curved surface to prevent the surface of the assembly 30 from being scratched when the assembly 30 is clamped by the clamping assembly 200, so that the aesthetic property of the assembly 30 is ensured, processes such as scratch removal are reduced, and the production efficiency is improved.
When the blow mold 10 of the present embodiment is operated, the assembly 30 is first placed into the portion of the molding cavity 110 corresponding to the upper mold 400 by a robot or manually, and is clamped and fixed by the clamping assembly 200, the preform is placed into the molding cavity to start blow molding, and after mold closing, blow molding is continued to perform so that the preform is blow molded into the blow molded product 20, and when the preform is blow molded into the blow molded product 20, the preform at least partially wraps the assembly 30 so that the blow molded product 20 from the preform is fixed to the assembly 30.
The present embodiment provides a blow mold 10, an inner wall surface 100 of the blow mold 10 defines a molding cavity 110 for molding a preform into a blow molded product 20, and the blow mold 10 includes a plurality of clamp assemblies 200. Each clamping assembly 200 is at least partially positioned within the molding cavity 110 for clamping a fitting 30 disposed within the molding cavity 110. And the blow mold 10 is configured to wrap the preform at least partially around the fitting 30 as the preform is molded to secure the preform-molded blow molded product 20 to the fitting 30. The blow mold 10 can assemble and fix the blow product 20 formed by the pre-forming piece and the assembly part 30, so that an additional production line for assembling and fixing the blow product 20 and the assembly part 30 is not required, the production process is simplified, the production efficiency is improved, the production cost is saved, and the integral aesthetic property after the blow product 20 and the assembly part 30 are assembled and fixed is improved.
