Three-Piece Blow Mold for Interlocking Beverage Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods are unable to effectively produce interlocking connectable beverage bottles due to manufacturing difficulties.
Innovation Solution
A three-piece mold system comprising a left upper mold portion, a right upper mold portion, and a lower mold portion, which allows for the formation of a combined upper and lower molding cavity to create a connectable beverage bottle, with specific movements and blow molding processes to facilitate the production of interlocking bottles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional single-piece or two-piece mold designs are used, then the manufacturing process is simpler, but interlocking connectable beverage bottles cannot be manufactured
Solution Approach 1:
The mold is divided into three separate portions: a first upper mold portion, a second upper mold portion, and a lower mold portion. Each portion can be independently positioned and removed, enabling the manufacturing of bottles with interlocking features that require complex cavity formation and release mechanisms.
2Adaptability or versatility
If a three-piece mold system is used to manufacture interlocking connectable bottles, then manufacturing capability is achieved, but the mold assembly and disassembly process becomes more complex
Solution Approach 1:
The mold portions are designed with dynamic positioning capabilities, allowing them to be moved independently during the molding and demolding processes. The upper mold portions can be positioned side-by-side to form complete cavities and then separated for bottle removal, while the lower mold portion remains stationary or moves independently.
3Manufacturing precision
If the upper mold portions are positioned side by side to form combined cavities, then complete bottle shaping is achieved, but the lateral removal process requires precise coordination
Solution Approach 1:
The upper mold portions are segmented into separate entities that can be independently manipulated. This segmentation allows them to be positioned side-by-side to form complete cavities during molding, and then laterally separated in a coordinated manner to enable bottle removal without disturbing the lower mold portion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the efficient manufacturing of interlocking connectable beverage bottles, improving storage and logistics efficiency by allowing for easy assembly and disassembly of mold components.
Implementation Method 1
compressed air is injected into the blow pin, such that the heated preform mold is blown into the shape of the entire molding cavity to form a connectable beverage bottle

AI summary
A system for molding includes: right and left upper mold portions; and a lower mold portion, such that the right and left upper mold portions are positionable side by side and the lower mold portion is positionable between lower ends of the right and left upper mold portions to form an entire molding cavity for blow molding a connectable beverage bottle, such that the lower mold portion is vertically downward removable and the right and left upper mold portions are laterally removable after blow molding of the connectable beverage bottle. Also disclosed is a method of molding, including: preparing blow pin, assembling mold components, performing blow molding, removing blow pin, disassembling mold components, and extracting the connectable beverage bottle.
