Core-Setting Apparatus with Rotatable Handling Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional core-setting apparatuses for flaskless molding apparatuses face complexity in structure and accuracy issues due to the need for a drag flask to move forward and backward, making it difficult to maintain the core's position accurately during the molding process.
Innovation Solution
A core-setting apparatus with a handling tool supported by a rotatable rod, a carrier for transferring the handling tool, and an actuator for lowering and lifting the cope flask, allowing the core to be accurately positioned and set in the lower mold by separating the upper and lower mold and match plate, simplifying the structure and maintaining core accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drag flask is made movable forward and backward to enable core setting, then the core-setting function is achieved, but the apparatus structure becomes complicated
Solution Approach 1:
The patent introduces a carrier as an intermediary component that holds the handling tool and transfers it to the molding apparatus. This carrier acts as a mediator between the core-setting apparatus and the drag flask, eliminating the need for the drag flask itself to be movable. The carrier is moved by an actuator to position the handling tool over the drag flask,从而实现 core setting without complicating the drag flask structure
Solution Approach 2:
The patent divides the core-setting function into separate components: a handling tool for holding the core, a carrier for transferring the handling tool, and an actuator for moving the carrier. This segmentation allows each component to perform its specific function independently, simplifying the overall apparatus structure compared to making the entire drag flask movable
2Ease of operation
If the drag flask is positioned outside the apparatus by moving forward to set the core, then the core-setting operation is enabled, but the core position accuracy deteriorates due to cantilevered support
Solution Approach 1:
The carrier serves as a stable intermediary platform that is moved by an actuator mounted on the main body of the molding apparatus. This ensures the carrier is supported by a stable structure rather than cantilevering from the drag flask, maintaining positioning accuracy while enabling the core-setting operation
Solution Approach 2:
The handling tool is preliminarily positioned on the carrier before the core-setting operation. The carrier is moved to the correct position over the drag flask, and then the handling tool is lowered to set the core. This preliminary positioning ensures accuracy by establishing the correct position before the actual core-setting action occurs
