Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in producing casting cores with finely structured walls on an industrial scale, where the existing devices face difficulties in demolding due to the circumferentially closed shape, requiring considerable effort and complicating large-scale, rapid series production.
Innovation Solution
The device divides the inner slide into multiple segments that can be adjusted to expand the mold cavity width for collision-free removal, allowing for the production of tubular cores with finely structured walls by minimizing the number of wide dividing gaps and simplifying the assembly process.

Engineering Contradiction Analysis
1Manufacturing precision
If the inner slide is used to produce casting cores with circumferentially closed shape, then the cores can be produced with fine interior space, but the demolding process becomes complicated and requires considerable effort
Solution Approach 1:
The inner slide is divided into multiple segments that can be independently moved relative to each other. During demolding, these segments are separated to expand the mold cavity width, allowing the core to be removed without complex operations. This segmentation enables both precise core formation and easy demolding.
Solution Approach 2:
The inner slide segments are designed to be dynamically adjustable between a closed position (for precise core formation) and an expanded position (for easy demolding). This dynamic reconfiguration allows the system to optimize for different operational phases.
2Ease of operation
If the inner slide is divided into multiple segments to facilitate demolding, then the demolding process is simplified, but the device complexity increases
Solution Approach 1:
The inner slide is divided into multiple segments that can be independently moved relative to each other. During demolding, these segments are separated to expand the mold cavity width, allowing the core to be removed without complex operations. This segmentation enables both precise core formation and easy demolding.
Solution Approach 2:
The inner slide segments are designed to be dynamically adjustable between a closed position (for precise core formation) and an expanded position (for easy demolding). This dynamic reconfiguration allows the system to optimize for different operational phases.
3Ease of operation
If the clear width of the mold cavity is increased for demolding, then the core removal becomes collision-free, but the manufacturing precision of the core may be compromised
Solution Approach 1:
The mold cavity width is dynamically adjusted: during core formation, the inner slide segments are in a closed position providing precise dimensional control; during demolding, the segments are separated to expand the cavity width for collision-free core removal.
Solution Approach 2:
The inner slide is divided into multiple segments that can be independently moved relative to each other. During demolding, these segments are separated to expand the mold cavity width, allowing the core to be removed without complex operations. This segmentation enables both precise core formation and easy demolding.

AI summary
The present invention relates to a device (1; 100) for shooting a casting core (G) that encloses a free inner chamber (I) at its outer boundaries, wherein the device (1; 100) has a mould cavity (5) that forms the casting core (G), which mould cavity encircles an inner slide (2) that extends along a longitudinal axis (LZ) and is bounded on its external side by an outer slide (3) that encircles the mould cavity (5), wherein the inner width (W) of the mould cavity (5) is determined by the distance between the inner surface (7) of the outer slide (3) allocated to the mould cavity (5) and the outer surface (6) of the inner slide (2). The device (1; 100) according to the invention enables operationally reliable production, including on a large scale, of casting cores (G) that have a basic tube shape but a fine wall structure. This is achieved in that the inner slider segments (2a-2e) can be adjusted between a receiving position, in which they are positioned closer to each other and to the longitudinal axis (LZ) of the inner slide (2) and the inner width (W) of the mould cavity between the inner slide (2) and the outer slide (3) is enlarged, and a shooting position, which is closer to the outer slide (3) and in which the inner width (W) of the mould cavity (5) corresponds to a specification for the casting core (G) to be shot.
