Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mould opening and closing mechanisms, as well as bottom mould elevating mechanisms in bottle blowing machines are complex and bulky, leading to operational inconvenience and high costs due to self-driven components.
Innovation Solution
A simplified linkage system utilizing a single rotation shaft to drive both mould opening and closing, and bottom mould elevating mechanisms, featuring a protrusion with a guiding groove and sliding block, and a locking mechanism with convex platforms and pins, allowing for coordinated movement and locking of mould plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional self-driven mechanisms are used for mould opening/closing and bottom mould elevating, then each function can operate independently, but the device complexity and bulkiness increase significantly
Solution Approach 1:
The patent combines the mould opening/closing mechanism and bottom mould elevating mechanism into a single integrated system. The moving mould plate serves dual functions: when it moves horizontally, it opens/closes the mould, and when it moves vertically, it elevates the bottom mould. This merging of functions reduces the number of separate mechanisms from two independent self-driven systems to one unified mechanism, directly addressing the technical contradiction by reducing device complexity while maintaining operational independence through coordinated motion.
Solution Approach 2:
The moving mould plate is designed as a universal component that performs multiple functions. It acts as both the actuator for mould opening/closing (through horizontal movement) and the actuator for bottom mould elevating (through vertical movement). This multi-functionality eliminates the need for separate dedicated mechanisms for each function, thereby reducing overall device complexity while preserving the ability to independently control both operations through the single moving mould plate.
2Reliability
If multiple independent mechanisms are used for mould opening/closing and bottom mould elevating, then each mechanism can be optimized for its specific function, but the overall system cost and operational complexity increase
Solution Approach 1:
The patent merges two independent mechanisms into one integrated system where the moving mould plate performs both mould opening/closing and bottom mould elevating functions. This reduction from multiple mechanisms to a single unified mechanism decreases system complexity and the number of potential failure points, thereby improving reliability while maintaining the functional independence needed for reliable operation of both functions.
3Power
If separate self-driven mechanisms are used for mould opening/closing and bottom mould elevating, then each function has dedicated driving force, but the device becomes bulky and operation becomes inconvenient
Solution Approach 1:
The patent combines the driving functions into a single system where the moving mould plate, when actuated, provides the driving force for both mould opening/closing and bottom mould elevating simultaneously. This eliminates the need for separate self-driven mechanisms with their own dedicated driving forces, reducing device bulkiness while maintaining adequate power delivery to both functions through the unified moving mould plate actuation.

AI summary
A linkage of mould opening and closing and bottom mould elevating is provided in the invention. The linkage comprises a mould opening and closing assembly, an elevating assembly and a driving assembly for driving the movement of the mould opening and closing assembly and the elevating assembly. The mould opening and closing assembly comprises a bottom mould, a fixed mould plate disposed on the machine frame of the bottle blowing machine, and a moving mould plate cooperating with the fixed mould plate. The elevating assembly comprises a protrusion, an elevating rod and a sliding block fixed on the lower portion of the elevating rod. A sliding groove extending in up-down direction is opened on the protrusion, and the sliding block is slidably disposed in the sliding groove. The bottom mould is fixed on the upper end of the elevating rod. The driving assembly comprises a rotation shaft rotatable around its' shaft axis, a driving source for driving the rotation of the rotation shaft. The moving mould plate and the protrusion are fixedly connected with the rotation shaft. The linkage of the mould opening and closing assembly and the elevating assembly are driven by one rotation shaft. Thus, the driving is achieved by a simple configuration, and the whole device of the invention is simple in structure and convenient in operation.
