1. Product Definition
A Die Casting Mold is a kind of steel mold. By injecting molten metal into the mold cavity under high pressure and rapidly cooling it to form, metal parts with high precision and high surface quality are finally obtained.
2. Core Features
High precision: The tolerance can reach ±0.02mm, suitable for complex geometric shapes.
High durability: Made of high-quality die steel (such as H13, SKD61), the service life can reach hundreds of thousands of times.
High-efficiency production: Supports rapid cycles (several times per minute), suitable for mass production.
Surface treatment: Chromium plating, nitriding and other processes enhance wear resistance and anti-sticking properties.
3. Main structural components
Component Function Description
The fixed mold (fixed side) is connected to the fixed end of the die-casting machine and includes the gating system (gate, runner).
The moving mold (moving side) is connected to the ejection mechanism of the die-casting machine. After forming, the mold is opened and the part is ejected.
The mold core/cavity is a precision component that directly forms the shape of the product and needs to be resistant to high temperatures and corrosion.
The ejection system's ejector pin, push plate and other mechanisms are used for demolding.
The waterway design of the cooling system ensures rapid and uniform cooling, shortening the cycle.
The exhaust system removes the gas in the mold cavity to reduce the porosity defect.
4. Applicable materials and processes
Common alloys: aluminum alloy (ADC12), zinc alloy (Zamak), magnesium alloy, etc.
Process types: Cold chamber die casting (suitable for high-melting-point alloys), hot chamber die casting (low-melting-point alloys).
5. Application fields
Automobile: Engine housing, transmission components, brackets.
Electronics: Heat sinks, connector housings.
Household appliances: Hardware parts, structural parts.
Industry: Pump bodies, valve parts.
6. Examples of technical parameters
Project parameter range/description
The lifespan of the mold is 500,000 to 1,000,000 times (depending on the material and maintenance).
The mold size is customized according to the product (commonly 300mm×300mm to over 1500mm).
Surface roughness: Ra0.8-1.6μm (can be polished to mirror finish)
Operating temperature: 150-300℃ (Preheating required)
7. Advantages and Customer Value
Cost reduction: The cost per piece is extremely low when produced in large quantities.
High consistency: Reduces the demand for subsequent machining.
Complex design: Supports thin-walled, threaded and insert forming.
8. Selection and Customization
3D drawings or samples of the product need to be provided, clearly stating the material and output requirements.
Customization cycle: Usually 4 to 8 weeks (depending on the complexity).
9. Maintenance and care
Regularly clean the residual metal in the mold cavity.
Check the smoothness of the cooling system.
Lubricate the ejector pins and guiding components.
