Blow Mold Unit Integral Handling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blow molding technologies face difficulties in handling blow cavity split molds and raised-bottom molds as an integral unit, leading to poor attachment and removal workability due to separate driver devices and complex exchange processes.
Innovation Solution
A blow mold unit is designed with a base-secured configuration that integrates blow cavity split molds and raised-bottom molds, using securing plates, pressure-receiving plates, and shafts to facilitate simultaneous attachment and removal, eliminating the need for horizontal tie rods and improving handling by allowing upward and downward movement of raised-bottom molds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate driver devices are used for blow cavity split molds and raised-bottom molds, then each mold can be independently controlled, but attachment and removal workability deteriorates due to complex handling procedures
Solution Approach 1:
The patent combines separate driver devices into a single integrated driver device that simultaneously controls both the blow cavity split molds and raised-bottom molds. This merging allows the molds to be attached and removed as an integral unit, eliminating the complex handling procedures required when separate driver devices are used, while maintaining independent control capability through coordinated movement mechanisms.
2Stability of the object's composition
If horizontal tie rods are used to connect blow molds, then structural stability is improved, but device complexity increases and sliding transfer becomes difficult
Solution Approach 1:
The patent removes the horizontal tie rod connection structure entirely and replaces it with a vertical integration system where the raised-bottom mold is positioned above the blow cavity split molds and controlled by a single driver device. This extraction of the horizontal connection element simplifies the overall structure, enables sliding transfer along the base, and maintains structural stability through the vertical arrangement and integrated driving mechanism.
3Volume of moving object
If raised-bottom mold is positioned under the base, then space utilization is improved, but exchange work becomes troublesome due to difficult accessibility
Solution Approach 1:
The patent repositions the raised-bottom mold from a horizontal arrangement under the base to a vertical arrangement above the base, where it can be freely moved upward and downward. This dimensional change maintains compact space utilization while dramatically improving accessibility and exchange workability, as the mold is now accessible from the top side rather than requiring access from underneath the base structure.
