Many potential new purchasers of die castings do not understand what a die casting mold looks like or what the different types of molds that can be constructed are. The choice of which type of die casting die the customer requires is usually determined by the following:.
These are the most common types of tools produced.
They range from a single-cavity die with no slides, to a multiple-cavity die with any number of slides. The cavities are made from high-quality tool steel, retained in a quality holder block.
The tool steel is heat treated to exacting standards that increase the life of the die cavities. Slides are components in the die that allow the casting to be formed with undercuts thus eliminating secondary machine operations and reducing part cost for higher quantity parts.
Die Casting Process Types
Production dies are built to critical dimensions, coring the maximum amount of stock from the casting, and allowing the agreed-upon amount of machining. Die A is a unit mold with 1 cavity; Die B is a unit mold with 3 cavities.
The center is part of the unit frame. A unit die is a special type of production die that is used for lower volume and smaller sized parts. It is a lower cost production tool that has a standardized main die frame and replaceable cavity units. These replaceable units are designed to be removed from the main die frame without removing the standard frame from the die casting machine.
This feature allows for quicker die set up time and becomes more effective for lower volume production runs. The most common commercial types of unit dies are single and double unit holders.
Unit dies limit the use of core slides because of the configuration needed for interchangeable unit inserts and the limited space available. The trim die is a tool that trims the runner, overflows, and flash from the casting.
Types of Die Casting Processes
The trim dies are single or multiple cavity tools, made in the same configuration as the die casting die. Depending on the shape of the casting, the trim die may be a simple open-and-close trim die or it may include as many slides as the die casting tool.
In some cases multiple station trim dies will be used for successive trimming operations. Trim dies require as much attention to detail in design as the die casting tools, and the use of quality materials should be specified to extend their productive life. They also reduce the labor cost in the deflashing of the die casting.
Aluminum Die Casting – Types of Die Casting Dies
The grade of tooling materials to be used in the construction of a die casting die should be specified as high quality, at a minimum, and preferable premium quality. These requirements are based on the extremely high temperatures and pressures used in die casting production.
Tooling grade requirements will vary depending on the tooling component, the alloy being die cast, the critical character of the cast part design and the long-term production quantities desired.
