Tiltable Casting Mold Linkage for Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing casting apparatuses face difficulties in performing maintenance on the upper mold due to its downward-facing orientation, making it challenging to access and maintain the mold effectively.
Innovation Solution
A casting apparatus with openable, closable, and tiltable upper and lower molds, incorporating a lifting/lowering mechanism that tilts the frames, allowing the molds to be tilted for easier maintenance, and a drive unit connected to the main link member to reduce the load on the lifting/lowering mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the upper mold is positioned facing down for casting, then the casting function is achieved, but maintenance work on the upper mold cannot be performed easily
Solution Approach 1:
The upper mold is made tiltable through the lifting/lowering mechanism that rotates the main link member, allowing the mold to change its orientation dynamically. During casting, the mold maintains its facing-down position, but during maintenance, it can be tilted to an upward-facing or sideways position for easy access, thus resolving the contradiction between casting function and maintenance accessibility
Solution Approach 2:
The system is divided into independent functional components: the upper mold, main link member, sub-link member, and lifting/lowering mechanism. This segmentation allows the upper mold to be independently tilted for maintenance while the other components remain in their operational positions, enabling separate optimization of casting and maintenance functions
2Ease of operation
If the lifting/lowering mechanism directly lifts the main link member with the drive unit connected, then the tilting function is achieved, but the load on the lifting/lowering mechanism increases
Solution Approach 1:
The sub-link member is introduced as an intermediary between the lifting/lowering mechanism and the main link member. The lifting/lowering mechanism only needs to lift the lighter sub-link member rather than the entire main link member assembly, significantly reducing the load on the lifting mechanism while still achieving the tilting function through the sub-link member's rotation

AI summary
A casting apparatus according to the present disclosure includes an upper frame, a lower frame, a main link member, a sub-link member and a lifting/lowering mechanism. The upper mold is attached to the upper frame. The lower frame is disposed in parallel with the upper frame. The lower mold is attached to the lower frame. A top end part of the main link member is rotatably connected to the upper frame and a bottom end part thereof is rotatably connected to the lower frame. The sub-link member is disposed in parallel with the main link member, the top end part thereof is rotatably connected to the upper frame and the bottom end part thereof is rotatably connected to the lower frame. The lifting/lowering mechanism causes the sub-link member to lift or lower with respect to the main link member.
