Solution Overview

Problem

Existing casting machines face challenges in producing high-quality cast products with complex geometries due to issues like porosity, contamination with oxides, and air pockets, particularly when dealing with complex shapes, as they are limited by the radial arrangement of the sprue and lack of flexibility in mold positioning.

Innovation Solution

A casting machine and method that allows the casting mold to be tilted about two axes, enabling movement in three dimensions, which adapts to the shape of the product, prevents air pockets and oxide contamination, and allows for more flexible sprue positioning, using a pivoting device controlled by a sensor and control system to regulate the tilting and melt flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the casting mold is arranged with the sprue positioned radially relative to the filling axis, then the casting machine structure is simple, but the product design is limited and complex shapes cannot be cast with high quality

Engineering Contradiction:
Improvecasting machine structureVSAvoidproduct design flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The casting mold is made dynamically tiltable about two transverse axes during the filling process, allowing the mold orientation to change dynamically to adapt to complex product geometries while maintaining a relatively simple radial sprue arrangement

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system adds rotational degrees of freedom by enabling tilting about two transverse axes, transforming the mold positioning from a single fixed orientation to multi-dimensional adjustable orientation, thereby achieving complex shape casting capability without complicating the fundamental radial sprue structure

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the melt is poured into the casting mold without tilting about two axes, then the filling process is simple, but air pockets, cold running, and oxide contamination occur

Engineering Contradiction:
Improvefilling processVSAvoidproduct quality
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The casting mold is dynamically tilted about two transverse axes during melt filling, creating dynamic motion that directs the melt flow to completely fill complex cavities while preventing air pockets, cold running, and oxide contamination

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the motion parameters of the casting mold by introducing dual-axis tilting, which modifies the melt flow characteristics and filling pattern to achieve complete cavity filling and eliminate casting defects

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If the casting mold is tilted about one axis only, then the mold can be moved in one plane, but complex product shapes cannot be filled completely and evenly

Engineering Contradiction:
Improvepivoting deviceVSAvoidmold filling quality
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The system adds a second transverse axis for tilting, expanding the mold movement from one plane to three-dimensional space, enabling complete and even filling of complex product geometries while keeping the pivoting device structure manageable

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
