Modular Mold System with Separation Tool for Vacuum Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing molds for forming structures with molding substances like sand or snow often create vacuums that make it difficult to separate the mold from the formed structure, leading to potential damage or loss of structural integrity.
Innovation Solution
A modular mold system comprising separable sections that can be connected and disconnected using securing devices like latches or buckles, with a separation tool to break the vacuum by inserting a blade or wedge between the sections, allowing for easier packing and removal of molding substance without damaging the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If packing or compacting molding substance in the mold to create a sturdier structure, then structural strength is improved, but vacuum is created making mold separation difficult
Solution Approach 1:
The mold is divided into multiple separable sections that can be independently removed from the molded structure. This segmentation allows the mold to be withdrawn in parts, reducing the vacuum adhesion force between the entire mold surface and the structure, while still maintaining the ability to pack molding substance firmly during the molding process.
Solution Approach 2:
A separation tool acts as an intermediary device inserted between the mold section and the molded structure. This tool breaks the vacuum seal by creating a small gap, allowing air to enter and equalize pressure, thereby facilitating mold removal without damaging the structure. The intermediary tool mediates between the need for strong packing and easy separation.
2Loss of substance
If creating a strong vacuum to retain molding substance in the mold during separation, then material retention is improved, but structure integrity deteriorates due to breaking or loss of structural integrity
Solution Approach 1:
Release channels are pre-formed in the mold sections, allowing air to be introduced at controlled locations before complete separation occurs. This preliminary action prevents the need for strong vacuum retention by allowing gradual pressure equalization, thereby avoiding sudden forces that could break the molded structure while still maintaining adequate material retention during molding.
Solution Approach 2:
The release channel acts as an intermediary pathway for air flow between the interior and exterior of the mold. This controlled intermediary channel allows gradual pressure equalization rather than sudden vacuum release, protecting the molded structure from shock forces while still enabling complete separation.
3Ease of operation
If using vertically-removed molds to simplify removal process, then ease of operation is improved, but structural elements farther from central axis cannot be formed
Solution Approach 1:
The mold is segmented into multiple sections that can be arranged in different configurations. Some sections can be removed vertically while others are positioned to form complex structures with elements extending from the central axis. This segmentation provides versatility in forming various structure types while maintaining relatively simple removal processes for each section.
Solution Approach 2:
Instead of limiting removal to a single vertical direction, the segmented mold allows sections to be removed in multiple directions and orientations. This dimensional flexibility enables the formation of complex structures with elements at various positions relative to the central axis, while each individual section can still be removed using simple vertical or lateral motions.

AI summary
Systems, methods, and articles of manufacture provide for a mold system for molding structures (e.g., sand castles) from one or more various types of molding substances (e.g., sand, clay, snow). In one embodiment, a mold system comprises a split mold comprising at least two mold sections. In one embodiment, a modular mold system allows for different types of mold sections with corresponding joining elements to be joined together to create forms for molding various types of structures. In some embodiments, mold sections are configured to facilitate the breaking of a vacuum created when molding substances are packed into the mold system, thus making it easier to separate a mold from the formed structure.
