Solution Overview

Problem

The existing forming machines without pattern casting face challenges in moving the workbench conveniently due to the need for a special lifting tool and are unable to efficiently machine large complex casting molds with large size structures and complex curved surfaces, leading to complex operations, sand cutting dispersion, and severe dust pollution.

Innovation Solution

A forming machine equipped with a multi-axis motion system, including a five-axis motion system, a moving platform system, and a lifting device, which allows for the linkage between the workbench and the moving bracket, enabling easy movement and precise machining of large and complex casting molds without the need for a lifting tool, and incorporates a sand discharge system to reduce dust pollution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a special lifting tool is used to move the workbench, then the workbench can be moved, but the operation process becomes complex and inconvenient

Engineering Contradiction:
Improveworkbench movement convenienceVSAvoidlifting tool requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the lifting function from a separate special lifting tool and integrates it into the moving platform system itself. The moving platform incorporates a lifting device that directly lifts and supports the workbench, eliminating the need for external lifting tools and simplifying the operation process.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the moving bracket and lifting device into an integrated moving platform system that handles both horizontal movement and vertical lifting of the workbench. This merging of functions into a single system reduces operational complexity and improves ease of use.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If conventional casting manufacturing process is used, then casting molds can be produced, but the manufacturing cycle is long and productivity is low

Engineering Contradiction:
Improvecasting production efficiencyVSAvoidmanufacturing cycle
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical pattern casting processes with a numerical control cutting system that directly machines sand molds from sand blanks. This substitution of conventional casting methodology with NC machining technology significantly reduces manufacturing cycle time and increases productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of mold creation from pattern-based assembly to direct NC cutting machining. By altering the manufacturing approach from traditional casting to numerical control forming, the system achieves faster production cycles and higher efficiency.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If numerical control cutting equipment is used to machine sand molds, then production cycle is shortened, but sand cutting dispersion and dust pollution occur

Engineering Contradiction:
Improvemachining speedVSAvoiddust pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful dust generated by NC cutting into a manageable byproduct by implementing a sand discharge system. The system collects and directs cut sand through designated channels, transforming the harmful dispersion into a controlled discharge process that reduces workshop pollution.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Adaptability or versatility

If the forming machine cannot machine large complex casting molds, then equipment requirements are met, but the application scope is limited

Engineering Contradiction:
Improvecasting mold machining capabilityVSAvoidcomplex curved surface machining accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent enhances the universality of the forming machine by equipping it with a multi-axis motion system capable of handling various casting mold types. The system can machine both simple and complex curved surfaces, as well as accommodate different mold sizes, thereby expanding its application scope while maintaining manufacturing precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)
