The strength and toughness of die casting machine template equipment parts are key factors to ensure that the high-strength die-casting requirements are met.
1. Material selection
High-strength alloy steel: High-strength alloy steel is usually selected. These materials have excellent mechanical properties, including high strength and high toughness.
Special alloy materials: In some special applications, high-strength special alloy materials may need to be used, such as hot work die steel H13, which can still maintain high strength and good toughness at high temperatures.
2. Heat treatment process
Quenching and tempering treatment: Through quenching and tempering treatment (quenching + high-temperature tempering), the material can obtain the best comprehensive mechanical properties, that is, high strength and high toughness. Quenching and tempering treatment can refine the grains, improve the internal structure of the material, and improve strength and toughness.
Surface hardening treatment: Surface hardening treatment technology, such as carburizing, nitriding, etc., is used to improve the hardness and wear resistance of the surface while maintaining the toughness of the core.
3. Structural design optimization
Reasonable cross-sectional design: Optimize the cross-sectional design of parts to avoid stress concentration and improve overall strength and toughness. For example, adopt arc transition, increase section thickness and other design methods.
Modular design: Modular design is adopted to facilitate replacement and maintenance, while ensuring that each module has good strength and toughness.
4. Manufacturing process control
Precision casting or forging: Precision casting or forging process is adopted to ensure uniform internal structure of parts and components, reduce defects such as pores and inclusions, and improve the strength and toughness of materials.
Processing accuracy control: Strictly control processing accuracy to ensure that the size and shape of parts meet the design requirements and avoid the decrease of strength and toughness due to processing defects.
5. Quality inspection and control
Non-destructive testing: Use non-destructive testing technologies such as ultrasonic testing and X-ray testing to conduct comprehensive quality inspection of parts and components to ensure that there are no internal defects.
Mechanical property testing: Conduct mechanical property tests such as tensile tests and impact tests to ensure that the strength and toughness of parts and components meet the design requirements.
6. Surface treatment
Surface coating: Wear-resistant and corrosion-resistant coatings are applied to the surface of parts and components, such as carbide coatings, ceramic coatings, etc., to improve the wear resistance and corrosion resistance of the surface, while protecting the strength and toughness of the base material.
Polishing and grinding: Polish and grind the surface to improve the surface finish and dimensional accuracy, reduce friction and wear, and extend the service life of parts.
7. Environmental adaptability design
High temperature resistant design: For the high temperature environment that may be encountered during the die-casting process, adopt high temperature resistant design, such as selecting high temperature resistant materials, optimizing the cooling system, etc., to ensure that the parts can still maintain strength and toughness at high temperatures.
Corrosion resistant design: For the corrosive environment that may be encountered during the die-casting process, adopt corrosion resistant design, such as selecting corrosion resistant materials, coating the surface with anti-corrosion coating, etc., to extend the service life of parts.
8. Simulation and optimization
Finite element analysis: Stress analysis and optimization design of parts are performed through finite element analysis (FEA) to ensure maximum strength and toughness under actual working conditions.
Simulation test: Simulation test is performed during the design stage, such as high temperature simulation, stress strain simulation, etc., to verify the rationality and reliability of the design.
Through the above-mentioned multi-faceted design and optimization, the die casting machine template equipment components can meet the high-strength die-casting requirements, ensuring that they can still maintain high strength and high toughness under high pressure, high temperature and high frequency working conditions, extending the service life of the equipment and improving production efficiency.
