Separable Middle Frame for Rubber Sole Thermoforming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rubber sole thermo-molding machines face challenges such as obstructed cleansing and material feeding operations due to a non-separable middle frame and push mechanism, leading to safety risks like burns and hand clamping, and inefficient operation space.
Innovation Solution
The middle frame is designed to be separable from the push mechanism, allowing the middle frame to be pushed out and the upper mold to tilt, enabling safer and more efficient cleansing and material feeding operations by eliminating space obstacles and preventing accidental injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the middle frame and push mechanism are connected and non-separable, then the structural stability is improved, but the ease of operation deteriorates due to obstructed cleansing and material feeding operations
Solution Approach 1:
The push mechanism is divided into a fixed portion (connected to the upper mold seat) and a movable portion (connected to the middle frame). The movable portion can be separated from the middle frame during cleansing operations, allowing the middle frame to be removed without the push mechanism, thereby improving ease of operation while maintaining structural stability during molding operations
Solution Approach 2:
The connection between the push mechanism and middle frame is made dynamic rather than static. The movable portion of the push mechanism can be engaged or disengaged from the middle frame based on operational requirements, enabling flexible adjustment between stable connected state during molding and separated state during cleansing operations
2Device complexity
If the middle frame and push mechanism are connected, then the device complexity is reduced, but safety deteriorates due to risks of burns and hand clamping
Solution Approach 1:
By segmenting the push mechanism into fixed and movable portions that can be separated from the middle frame, the invention reduces safety hazards. During cleansing operations, the middle frame can be removed without the push mechanism, eliminating the risk of hand clamping between the push mechanism and middle frame, and improving access to reduce burn risks
Solution Approach 2:
The movable portion of the push mechanism is extracted from the middle frame during cleansing operations. This separation removes the potential hazard source (push mechanism) from the operation area, preventing hand clamping injuries and improving user safety while maintaining the simplified structure during actual molding operations
3Manufacturing precision
If the middle frame is non-separable from the push mechanism, then the manufacturing precision is maintained, but productivity deteriorates due to blocked cleansing operation
Solution Approach 1:
The push mechanism is segmented into fixed and movable portions, allowing the movable portion to be separated from the middle frame during cleansing operations. This enables efficient cleaning of the molding cavity without compromising the structural integrity and positioning precision during actual molding operations, thereby improving productivity while maintaining manufacturing precision
Solution Approach 2:
The dynamic connection between the push mechanism and middle frame allows the system to adapt between two states: a connected state during molding operations that ensures positioning precision, and a separated state during cleansing operations that improves productivity by enabling unobstructed access for cleaning

AI summary
A rubber sole thermo-molding machine includes a lower mold seat disposed on a hydraulic actuator of the machine seat. The lower mold seat ascends and descends with respect to the upper mold seat according to the hydraulic actuator, allowing the lower upper molds to close and open. The upper mold seat moves between a normal position and a tilt position according to the turning mechanism. The middle plate horizontally moves between the upper and the lower mold seats, and has a push mechanism connected with the middle frame. When the pin of the middle frame and the fasten unit on the push mechanism are separated, the middle frame is stacked on the middle plate or the lower mold to move, facilitating the cleansing and material-feeding operations. The user can cleanse the upper mold without being hindered by the middle frame, assuring the safe and smooth process.
