Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying release agents to molding rings for concrete workpieces face challenges in achieving cost-effective and uniform distribution while causing environmental strain and requiring excess agent collection.
Innovation Solution
A device with a profiled application roll, possibly made of open-pored foam, that rotates in the diameter plane of the molding ring, ensuring continuous contact and uniform release agent application, adapted for various ring shapes and sizes through a movable carriage and adjustable supply system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a spray application unit is used to apply release agent to the molding ring, then the release agent can be distributed over the mold faces, but environmental strain occurs and excess agent must be collected and reprocessed
Solution Approach 1:
An application roll serves as an intermediary carrier between the release agent supply and the molding ring. The roll absorbs the release agent on its upstream side and transfers it uniformly to the molding ring surface through controlled contact, eliminating direct spraying and the associated environmental problems while ensuring complete coverage.
Solution Approach 2:
The application roll is made of porous material that absorbs the liquid release agent into its structure. This absorption mechanism allows the roll to take up the agent on the upstream side and release it gradually through its pores during rotation, achieving uniform distribution without excess spray and eliminating the need for collection systems.
2Object-affected harmful factors
If an application roll is used to apply release agent without environmental strain, then cost-effective use is achieved, but uniform distribution over the entire mold face must be ensured
Solution Approach 1:
The application roll is profiled to match the specific geometry of the molding ring, creating locally adapted contact surfaces. This profiling ensures that the roll maintains continuous contact with the entire mold face profile, transferring release agent uniformly across all surfaces including complex geometries that would be difficult to reach with conventional spray methods.
Solution Approach 2:
The release agent is applied to the application roll before the roll contacts the molding ring. The porous roll absorbs and pre-distributes the agent uniformly across its surface area, ensuring that when it contacts the molding ring, the agent is already prepared for even transfer without concentration variations or missed areas.
3Manufacturing precision
If the application roll is adapted to the profile of the molding ring, then complete coverage is achieved, but the device must accommodate various ring shapes including circular, oval, or rectangular
Solution Approach 1:
The application roll is mounted on a movable carriage that can adjust its position radially toward or away from the molding ring. This dynamic positioning allows the roll to be brought into contact with different ring geometries and diameters, maintaining profiling adaptation for complete coverage while accommodating various shapes through positional adjustment rather than requiring multiple fixed rolls.
Solution Approach 2:
The profiling of the application roll is designed to be universally adaptable to different ring shapes (circular, oval, rectangular) through its contact geometry and positioning system. The same roll structure can serve multiple ring profile types by adjusting its position and orientation, making the device versatile without sacrificing profile-specific coverage quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, cost-effective, and environmentally friendly release agent application with uniform distribution across the mold faces, independent of ring shape or size, without requiring additional agent collection and minimizing environmental impact.
Implementation Method 1
the application roll comprises an open-pored foam body seated on a hub. Such a foam body, typically made of soft foam, absorbs the supplied release agent into its pores
Implementation Method 2
because of its porosity, additionally ensures distribution of the release agent within the foam body
Implementation Method 3
if the application roll is not driven and solely rolls on the molding ring because of friction as a result of its free rotatability

AI summary
A device is described for applying a release agent to a molding ring (1) for a front centering shoulder of a tubular or annular workpiece made of concrete having an application unit connected to a pump for the release agent. To provide advantageous application conditions, it is suggested that the application unit for the release agent have an application roll (4) preferably adapted to the profile of the molding ring (1), whose rotational axis (5) at least approximately runs in a diameter plane of the molding ring (1).
