Deformable Mold for Concrete Molding Overfill Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing molding stations face challenges in improving the quality of the lower outer surface of molded articles and recurrent issues of overfilling, particularly in concrete molding processes.
Innovation Solution
A molding station design featuring a deformable mold with a movable lower door and optional upper door, where the interior volume is temporarily reduced during filling by compressing the mold or using a feedbox to control the release of moldable material in stages, preventing overfilling and ensuring a smooth surface finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mold is filled quickly to increase productivity, then the filling speed increases, but overfilling occurs and surface quality deteriorates
Solution Approach 1:
The mold transitions from a rigid structure to a dynamic, deformable structure that can temporarily reduce its interior volume during filling. The deformable material allows the mold to adapt its shape and volume in real-time during the filling process, enabling high-speed filling without overfilling while maintaining surface quality.
Solution Approach 2:
The mold's physical state is changed from rigid to deformable, allowing it to temporarily reduce its interior volume during filling. This parameter change in the mold's structural properties enables precise control of material distribution and prevents overfilling even at high filling speeds.
2Manufacturing precision
If the mold interior volume is reduced to prevent overfilling, then material distribution improves, but the mold structure becomes more complex
Solution Approach 1:
The mold is constructed from deformable material that acts as a flexible shell, allowing the interior volume to be temporarily reduced during filling. This flexible structure simplifies the overall design compared to complex mechanical volume reduction mechanisms while achieving precise material distribution control.
Solution Approach 2:
The deformable mold automatically reduces its own interior volume in response to the filling process, eliminating the need for external control mechanisms. The mold's inherent deformability allows it to self-regulate its volume to prevent overfilling, reducing structural complexity.
3Manufacturing precision
If a deformable mold is used to control overfilling, then surface quality improves, but the mold material options are limited
Solution Approach 1:
The invention changes the physical state and mechanical properties of the mold material from rigid to deformable, enabling new functional capabilities. This parameter change allows the use of elastomeric materials that provide both the desired surface quality and the volume control functionality, expanding material options beyond traditional rigid molds.
Solution Approach 2:
The deformable mold can be constructed using composite materials that combine the flexibility needed for volume control with the surface finish properties required for quality articles. This allows selection from a broader range of materials that exhibit both deformability and appropriate surface characteristics.

AI summary
A molding station and method comprising a hopper having a mouth closable with at least a lower door and a mold to be filled, the hopper and the mold being movable to a filling position in which the hopper is closed by the lower door; the lower door then opening to allow an amount of moldable material to be released into the mold; the mold being made in a deformable material, so that an interior volume of the mold is temporarily reduced when releasing the moldable material into the mold.
