Solution Overview

Problem

Conventional die casting machines require high consumption of release agent liquid and time due to the need for separate spraying for cooling and die casting operations, leading to inefficiencies.

Innovation Solution

A dispenser system integrated with a die casting machine's nozzle mechanism, capable of mixing release agent, water, and air, allowing for adjustable and independent control of fluid outputs to reduce liquid consumption and operation time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate spraying is used for cooling and die casting operations, then the mold can be properly cooled and release agent can be applied, but the consumption of release agent liquid increases and operation time increases

Engineering Contradiction:
Improvemold cooling effectivenessVSAvoidrelease agent liquid consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent combines the cooling function and release agent application function into a single spraying operation. The spray device simultaneously sprays a mixture of water (for cooling) and release agent (for die casting), eliminating the need for separate spraying steps. This merging of functions directly reduces release agent consumption while maintaining effective mold cooling and proper release agent application.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spray device is designed to perform multiple functions: cooling the mold and applying release agent in one operation. The system uses a multi-component spray mechanism that can deliver water, release agent, or a combination thereof, allowing the same device to handle both thermal management and surface preparation functions, thereby reducing overall liquid consumption and operational time.

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

2Reliability

If separate spraying is used for cooling and die casting operations, then proper cooling and coating can be achieved, but the die casting operation becomes time-consuming

Engineering Contradiction:
Improverelease agent adherenceVSAvoiddie casting operation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the cooling spray and release agent spray into a single simultaneous spraying action. The spray device delivers both water and release agent together in one coordinated operation, eliminating the sequential timing of separate sprays. This directly reduces operation time while ensuring both cooling effectiveness and proper release agent adherence are achieved.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables continuous simultaneous delivery of cooling water and release agent during a single spraying phase. Rather than interrupting the process with sequential operations, the multi-component spray system maintains continuous useful action by delivering both functions concurrently, thereby reducing total operation time without compromising adherence quality.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If only release agent liquid is sprayed, then die casting surface preparation is achieved, but mold cooling is insufficient

Engineering Contradiction:
Improverelease agent application qualityVSAvoidmold temperature
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The spray device is designed with multi-functionality to handle both thermal management and surface preparation. It can spray water for cooling, release agent for surface preparation, or a combination of both simultaneously. This universal capability allows the system to address mold temperature control and release agent application quality together in a coordinated manner, preventing the trade-off between one function and the other.

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

4Ease of operation

If high pressure air is used to spray release agent liquid, then spraying capability is achieved, but liquid consumption increases

Engineering Contradiction:
Improvespray delivery capabilityVSAvoidrelease agent liquid consumption
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent combines the spraying of water and release agent into a single high-pressure air-driven spray operation. By merging the liquid delivery streams, the system achieves effective spray distribution with reduced total liquid consumption. The high-pressure air propels the mixed spray effectively, maintaining ease of operation while reducing the amount of release agent needed compared to separate spraying operations.

Inventive Principle:
Principle #5Merging (Combining)
