A die set is a jig and tool used to secure a die to a press for plastic forming. The upper and lower die set is connected by guide posts to support the vertical movement of the press in relation to the die.
The advantage of die set is that they can be used for plastic forming of products with multiple processes and different specifications by changing the die to which they are attached.
Since the die set serve as a guide, accurate concentricity and coaxiality and easy replacement of dies and other parts are important specifications required for die set.
Die sets are used as jigs and tools for metal forming and other plastic forming operations on presses.
Examples of formed products include bevel gears, helical gears, and various joints for automotive and industrial machinery parts.
Plastic forming is characterized by its ability to form products to near final shape in a small number of processes, enabling mass production of strong products at low cost.
Therefore, it is a processing method often used in the production of industrial machinery and automotive parts.
The structure of die sets consists of a mounting part for mounting on a press, a pressure-receiving part that transmits the pressure of the press to the die or product, and a forming part, that creates the shape of the die or other product.
The most important die part is divided into the punch side (upper side) and the die side (lower side), each of which is housed in a punch holder and die holder.
The parts that transmit these upper and lower presses are the guideposts, guide bushings, knock pins, and other pin holders, which support the vertical movement from the press machine.
Die sets have the advantage of being versatile jigs and tools that allow easy die changes. On the other hand, however, it is important to ensure eccentricity accuracy, which, if not maintained, will adversely affect product quality and the dies. Steel and aluminum alloy types are commonly used.
There are several types of positioning relationships between the guideposts and the mold, such as those with guide posts at four corners, those placed diagonally, and those placed at two locations on either side, depending on the application. There are also two types of guides: a plain type, which is easy to achieve high accuracy, and a ball guide type, which is suitable for larger sizes. In recent years, roller type guides with higher performance have also been introduced.
