Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current linkage devices between mold opening and closing and bottom mold in bottle-blowing machines have complex structures that limit stability and increase equipment costs, affecting the efficiency and reliability of the bottle-blowing process.
Innovation Solution
A linkage device with a connecting rod mechanism and drive mechanisms that allow the bottom mold base to move up and down and the mold opening and closing base to rotate, reducing the complexity between mold bases, enhancing operational stability, efficiency, and lowering equipment costs through a simplified design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex linkage device with many related parts is used to connect mold bases, then the mold bases can be linked together, but the stability of the mold bases is limited
Solution Approach 1:
The linkage device is divided into independent functional modules: a driving mechanism with a driving shaft and driving linkage arm, and a driven mechanism with a driven shaft and driven linkage arm. These modules are connected through simple linkage arms rather than a complex multi-part structure, reducing overall system complexity while maintaining stability through modular design
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate parts from the linkage system. The direct connection between the driving linkage arm and driven linkage arm through a simplified structural arrangement removes redundant components, thereby improving stability without adding complexity
2Device complexity
If a simplified linkage device is used between mold bases, then equipment cost is reduced and structure is simplified, but the working efficiency and stability may be affected
Solution Approach 1:
The driving mechanism is designed to perform preliminary rotational motion of the driving shaft, which through the linkage arms预先 establishes the correct positioning and timing for mold opening/closing and bottom mold lifting. This preliminary action ensures synchronized operation without requiring complex control systems, maintaining high working efficiency while simplifying the overall structure
Solution Approach 2:
The linkage device serves multiple functions simultaneously: it controls both the opening/closing of the mold bases and the lifting/lowering of the bottom mold base through a single integrated mechanism. This multi-functionality eliminates the need for separate control systems, improving working efficiency while keeping the structure simple and cost-effective

AI summary
A linkage for linking a mold that opens and closes relative to a bottom mold for a bottle-blowing machine, comprises a frame (1), a mold-opening/closing base and a bottom mold base (5), the mold-opening/closing base comprises a first mold base (3) and a second mold base (4), and the linkage comprises a second shaft (6), a first swing arm (7) with one end fixed onto the second shaft (6), a first drive mechanism for driving the opening and closing mold of the first mold base (3) and the second mold base (4), and a second drive mechanism for driving the bottom mold base (5) to go up and down; the second drive mechanism comprises a first connecting rod (9) with one end hinged to the bottom mold base (5) via a third shaft (8), and a second connecting rod (11) with one end hinged to the frame (1) via a fourth shaft (10), and the other end of the first connecting rod (9) and the other end of the second connecting rod (11) are hinged to each other via a fifth shaft (12); and the second drive mechanism further comprises a connecting rod mechanism with two ends being respectively hinged to the first swing arm (7) and the fifth shaft (12) for driving the bottom mold base (5) to go up and down. The linkage reduces the relevance between the mold bases, has a high working efficiency, simple and convenient operation, stable operation, and low equipment cost.
