Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flaskless molding machines with complex structures and increased costs due to the need for large components and additional tanks for sand supply, especially when using a matching plate of varying thickness, which complicates the molding process and requires additional components.
Innovation Solution
A flaskless molding machine design that allows for the use of both matching and pattern plates of varying thicknesses, with sand introduction openings on the side walls of the molding flasks and filling frames, enabling the positions of these openings to be adjusted based on the plate thickness, eliminating the need for additional components and simplifying the structure by using a single sand tank and reducing the number of driving means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a matching plate of varying thickness is used, then the molding machine can accommodate different plate thicknesses (8mm to 40mm), but the structure becomes complex and requires additional driving means and components
Solution Approach 1:
The patent applies the dynamics principle by making the sand introduction openings movable rather than fixed. The openings can be positioned at different heights on the side walls of the molding flasks according to the thickness of the matching plate, allowing the system to adapt dynamically to varying plate thicknesses without adding complex driving mechanisms. This dynamic positioning capability resolves the contradiction by enabling versatility while maintaining structural simplicity.
2Adaptability or versatility
If additional driving means and components are added to handle varying plate thickness, then the molding machine can accommodate different plate thicknesses, but the cost and maintenance requirements increase
Solution Approach 1:
The patent implements dynamics by enabling movable sand introduction openings that can be adjusted according to plate thickness. This dynamic adjustment mechanism allows the system to handle varying plate thicknesses (8mm to 40mm) without requiring additional driving means, thereby maintaining ease of manufacture and reducing costs while achieving adaptability.
3Device complexity
If a single sand tank is used, then the cost and structure are simplified, but the positions of sand introduction openings must be precisely adjusted for different plate thicknesses
Solution Approach 1:
The patent applies dynamics by making the sand introduction openings movable rather than fixed. This allows a single sand tank to work with varying plate thicknesses (8mm to 40mm) by adjusting the opening positions dynamically, thereby maintaining structure simplicity while achieving the necessary manufacturing precision for different configurations.
4Device complexity
If the opening positions are fixed, then the structure is simpler, but the machine cannot accommodate matching plates of different thicknesses
Solution Approach 1:
The patent implements the dynamics principle by making the sand introduction openings movable rather than fixed. This dynamic capability allows the structure to remain relatively simple while enabling the machine to accommodate matching plates of different thicknesses (8mm to 40mm), thus resolving the contradiction between structural simplicity and adaptability.

Implementation Method 1
into which spaces the molding sand is filled by air through the openings for sand-feed
Implementation Method 2
a pair of molding spaces is formed, each space being a space to produce a mold, into which spaces the molding sand is filled by air through the openings for sand-feed. Each of the openings is disposed on a wall of each of the two molding flasks that form the pair of molding spaces

AI summary
The present invention provides a flaskless molding machine that can use a matching plate of different thicknesses. The flaskless molding machine has two molding flasks that have a matching plate sandwiched between them, the two molding flasks being positioned in a way such that one of opening ends of the molding flasks is opposed to each other and each of the other opening ends of the molding flasks is engaged with a squeezing board, and a pair of spaces is formed, into which spaces molding sand is filled by air through each of the openings for introducing the molding sand, disposed on a wall of each of the two molding flasks that are opposed to each other, the flaskless molding machine thus constituted being able to mold two molds by squeezing the molding sand with the squeezing boards.
