Solution Overview

Problem

Current mold spray head adjustments in die casting processes are cumbersome, requiring manual intervention, leading to production downtime, ergonomic challenges, and safety risks due to high temperatures, and are not precise enough for optimal release agent application.

Innovation Solution

A mechanical device with a support frame and movable mold dies that allows for precise adjustment of the mold spray head outside the die-casting mold, enabling ergonomic and safe operation without interrupting the casting machine, using 3D-printed molds to replicate the die-casting mold contours for accurate nozzle positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual adjustment of the mold spray head is performed on the die-casting machine, then the nozzle angle and distance can be adjusted, but production time is lost and workers are exposed to high temperatures

Engineering Contradiction:

Improvenozzle positioning accuracyVSAvoidproduction downtime

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The device allows nozzle adjustment to be performed in advance on a separate support frame before the die-casting machine operation, so that when adjustment is needed, the machine can continue running while the spray head is adjusted externally and quickly reattached, eliminating production downtime

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If manual adjustment of the mold spray head is performed on the die-casting machine, then the nozzle angle and distance can be adjusted, but workers face burn risks from residual heat

Engineering Contradiction:

Improvenozzle positioning accuracyVSAvoidthermal exposure to operators

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The adjustment function is extracted from the hot die-casting machine environment and moved to a separate support frame that can be positioned away from heat sources, allowing workers to perform adjustments safely without thermal exposure while maintaining precision through the dedicated adjustment mechanisms

Inventive Principle:

Principle #2Taking out (Extraction)

3Manufacturing precision

If manual adjustment of the mold spray head is performed, then nozzle positioning can be adjusted, but the operation is ergonomically awkward and requires two workers

Engineering Contradiction:

Improvenozzle positioning accuracyVSAvoidadjustment ergonomics

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

A dedicated support frame serves as an intermediary structure that provides ergonomic working conditions for adjustment operations, with features like accessible positioning mechanisms, proper lighting, and comfortable access for operators, eliminating the need for two workers while maintaining precision

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention relates to a device for adjusting the mold spray head in the die casting process. This device comprises a support frame (1) and at least one mold die (2a, 2b, 2c, 2d, 2e, 2f) arranged on the support frame (1), wherein the support frame (1) is designed to support the mold spray head with a series of nozzles and wherein at least one section of the mold die (2a, 2b, 2c, 2d, 2e, 2f) with its shape copies the contour of the inner surface of the actual die casting mold for the production of the casting.
