Casting Mold Demolding via Synchronized Sliding Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing casting devices for producing cast aluminum in pressure or low-pressure processes face challenges in achieving simultaneous movement of adjustable components, leading to complex and expensive production processes that can damage the cast part during demolding.
Innovation Solution
The device employs a system of sliding surfaces with five pairs of sliding surfaces, including angled and horizontal pairs, to facilitate simultaneous and uniform movement of the cast part, allowing for non-destructive demolding by moving the cast part upwards and outwards, reducing distortion and surface damage, and enabling quick release from the mold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a known device with adjustable components is used, then the casting can be produced in pressure or low-pressure process, but the adjustable components cannot move simultaneously and the structure becomes complex and expensive
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated adjusting device that simultaneously controls both the vertical position of the top part and the horizontal position of side parts. This merging of adjustment mechanisms eliminates the need for separate complex adjustment systems while enabling coordinated movement of all mold components.
Solution Approach 2:
The patent introduces dynamic adjustability to the casting device, allowing the top part and side parts to be positioned and moved simultaneously during the demolding process. This dynamic capability enables the mold components to adapt their positions coordinate to facilitate damage-free casting removal, transforming a static mold structure into a dynamically adjustable system.
2Ease of operation
If conventional demolding method is used, then the casting can be removed from the mold, but damage to the casting surface and distortion occur
Solution Approach 1:
The patent employs dynamic positioning of mold parts during demolding, where the top part moves vertically and side parts move horizontally in a coordinated manner. This dynamic demolding process allows the casting to be released from all mold surfaces simultaneously and uniformly, preventing surface damage and distortion that occur with conventional static demolding methods.
Solution Approach 2:
The patent changes the spatial parameters of the mold components during demolding by adjusting the vertical position of the top part and the horizontal position of side parts. This parameter adjustment creates optimal clearance and separation between the casting and mold surfaces, enabling damage-free removal while maintaining casting precision.
3Measurement precision
If multiple adjusting devices are used for vertical and horizontal adjustment, then the components can be positioned, but the movement cannot be simultaneous and production time increases
Solution Approach 1:
The patent merges multiple adjustment functions into a single adjusting device that can simultaneously control the vertical position of the top part and the horizontal position of side parts. This unified adjustment mechanism enables coordinated movement of all mold components at the same time, eliminating the sequential adjustment process and significantly reducing demolding time while maintaining positioning accuracy.

AI summary
The invention relates to a device for producing cast parts, such as aluminum castings, in a pressure method or a low-pressure method using a casting tool (20) which consists of movably arranged lateral parts (4) with a base (1) that receives a lower part or a lower mold part (3) and a plate that has an upper part (7) or an upper mold part (5). At least the upper part (7) together with a removal plate (10) and the upper mold part (5) can be moved in the vertical direction (Z) relative to the standing surface of the casting tool (20) using at least one adjusting device (17), and the lateral parts (4) can likewise be moved in the horizontal direction (X) using the adjusting device and/or additional adjusting devices. The aim of the invention is to develop and arrange the device such that a simultaneous or synchronized movement of the adjustable components can be achieved with a uniform movement. According to the invention, this is achieved in that at least the one adjusting device (17) interacts directly or indirectly with the removal plate (10) in order to remove a cast part (9), and during a vertical adjusting process, the upper mold part (5) can first be moved in the perpendicular direction (Z) at least via the one adjusting device (17) and then the lateral parts (4) can be moved in the vertical direction (X) likewise at least via the one adjusting device.
