Mould Bottom Segmentation for Green Brick Demoulding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of Wasserstrich bricks, the absence of sand covering in mould cavities leads to green bricks sticking to the bottom, causing residue and soiling issues during demoulding, which affects the efficiency and cleanliness of the process.
Innovation Solution
A device with a bottom divided into a first and second part, where the second part is surrounded by the first, and a release plate that can move relative to the first part, along with a drive rod and stop mechanism to transmit impulses and air supply, reduces sticking by minimizing contact surface and facilitating release under gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the mould cavity is not covered with sand to maintain a smooth surface structure, then the brick surface quality is improved, but the green brick sticks to the bottom of the mould cavity during demoulding
Solution Approach 1:
The bottom of the mould cavity is divided into two parts: a first part that remains stationary and a second part that is movable and can be displaced relative to the first part. This segmentation allows the second part to be moved away from the green brick during demoulding, reducing adhesion and facilitating easy removal while maintaining a smooth surface structure.
Solution Approach 2:
The second part of the bottom is made movable rather than fixed, allowing it to change position dynamically during the demoulding process. This dynamic adjustment enables the bottom surface to transition from a static contact state during forming to a separated state during removal, solving the adhesion problem without compromising surface quality.
2Productivity
If the ejecting member is displaced away from the bottom to press the green brick, then the brick is successfully ejected, but clay residue remains between the ejecting member and bottom causing soiling
Solution Approach 1:
The bottom is segmented into a first part and a second part that can move relative to each other. When the ejecting member is displaced, the second part can be moved away from the green brick, preventing clay residue from accumulating between the ejecting member and the bottom surface, thus eliminating the soiling problem while maintaining ejection efficiency.
Solution Approach 2:
The second part of the bottom is extracted or separated from the first part during the ejection process, creating space between the ejecting member and the bottom surface. This extraction prevents clay residue from remaining in the gap, solving the contamination issue while preserving the ejection function.
3Object-generated harmful factors
If the bottom is divided into two parts with the second part surrounded by the first, then a flush surface is created reducing soiling, but the device complexity increases
Solution Approach 1:
The bottom is divided into two parts with the second part surrounded by the first part, creating a flush surface that reduces soiling. Although this segmentation increases structural complexity, it effectively prevents clay residue from accumulating and causes harm to the system.
Solution Approach 2:
The second part acts as an intermediary element between the first part and the green brick. It provides a movable interface that creates a flush surface, reducing direct contact between the ejecting member and the bottom, thereby minimizing soiling while managing the added structural complexity.

Function Achieved in This Case
The solution effectively prevents residue from sticking to the ejecting member and bottom, ensuring smooth demoulding and reducing material waste, while maintaining the smooth surface structure of Wasserstrich bricks.
Implementation Method 1
a drive rod (18) extending from the release plate (21) through the mould container bottom (23), wherein the drive rod (18) is configured to collide with the stop (16) in a stepwise displacement of the conveyor (6), thereby transmitting an impulse to the bottom (12)
Implementation Method 2
During demoulding the opening of the respective mould cavity is directed downward, whereby the force of gravity contributes to the green brick releasing from the bottom
