Single Shaft Linkage for Bottle Blowing Mould Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mould opening and closing mechanisms and bottom mould positioning mechanisms in bottle blowing machines are complex and bulky, leading to inconvenient operation and high costs due to self-driven configurations.
Innovation Solution
A simplified linkage system for mould opening and closing, and bottom mould positioning, utilizing a single rotation shaft to drive both mechanisms, with a mould opening and closing assembly that includes a moving mould plate, a fixed mould plate, and a bottom mould positioning assembly featuring a stop block, sliding block, swing member, and rotation member, allowing for compact configuration and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional self-driven configurations are used for mould opening and closing mechanism and bottom mould positioning mechanism, then each mechanism can operate independently, but the device complexity and volume increase significantly
Solution Approach 1:
The patent combines the mould opening and closing mechanism with the bottom mould positioning mechanism into a single integrated system. The moving mould plate serves dual functions: it acts as both the closing element for the mould and the positioning element for the bottom mould. This merging eliminates the need for separate self-driven mechanisms, thereby reducing device complexity while maintaining operational independence through the linkage design.
Solution Approach 2:
The moving mould plate is designed to perform multiple functions simultaneously. It not only executes the mould opening and closing action but also provides positioning and support for the bottom mould through its bottom surface. This multi-functionality reduces the number of components needed and simplifies the overall mechanism structure.
2Reliability
If separate self-driven mechanisms are used for mould opening and closing, and bottom mould positioning, then each function is independently controlled, but the overall volume and cost increase
Solution Approach 1:
The patent merges two separate mechanisms into one integrated system where the moving mould plate serves both as the actuator for mould closing and as the positioning device for the bottom mould. This consolidation reduces the overall volume required while maintaining functional independence through the linkage between the moving mould plate's rotational movement and the bottom mould's positioning action.
3Ease of manufacture
If conventional configurations with multiple components are used, then each component can be optimized for its specific function, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent combines multiple functions into the moving mould plate, which simultaneously performs mould closing and bottom mould positioning. This reduces the total number of components that need to be manufactured and assembled, thereby simplifying manufacturing processes and reducing costs, while the linkage design ensures that functional requirements are still met.

AI summary
A linkage of mould opening and closing and bottom mould positioning is provided in the invention. The linkage is mounted on a bottle blowing machine. The linkage comprises a mould opening and closing assembly and a bottom mould positioning assembly. The mould opening and closing assembly comprises a bottom mould movable relative to a machine frame in up-down direction, a fixed mould plate fixedly disposed on the machine frame, and a moving mould plate rotatable relative to the machine frame. The bottom mould positioning assembly comprises a stop block disposed at the bottom of the moving mould plate, a sliding block slidable relative to the machine frame, a swing member for driving the sliding of sliding block, and a rotation member rotatable relative to the machine frame for driving the swinging of the swing member relative to the machine frame during its' rotation. The rotation member and the moving mould plate are fixedly connected on a rotation shaft which is driven by a power source to rotate a second axis. When the mould opening and closing assembly is in the mould closing state, both the sliding block and the stop block are inserted between the bottom mould and the machine frame and contact against the bottom mould. When the mould opening and closing assembly is in the mould opening state, the moving mould plate is opened relative to the fixed mould plate, such that the stop block and the sliding block are detached from the bottom mould.
