In mold manufacturing process often hear some terminology, understand these terms, help to mold and mold design, processing and manufacturing have a clearer understanding.
A mold is a tool that makes a blank into a device with a specified shape and size under external forces. According to the nature of the molding, it can be divided into stamping die and die. Stamping die is divided into cold stamping die and hot stamping die, we are all cold stamping die.
1 、 metal stamping die:
It is a kind of stamping die, the metal sheets for the processing object through the press or hydraulic machine and mold, sheet cutting, tearing, separation, beading, drawing, forming various shapes of the products comply with the requirements of the people. According to the nature of process, they can be divided into 4 kinds: punching die, bending die, drawing die and forming die.
2 、 upper die and lower die:
The hardware mold is installed on the press or hydraulic press, and the normal operation is up and down, and the part that is mounted on the slide block is called the upper die part, which is referred to as the upper die. The part fixed on the worktable of the punch press is called the lower die part, hereinafter referred to as the lower die. The upper and lower dies are in pairs, and only the upper die or the die with the lower die can not work.
3, punch, die:
The die part used to form the inner surface of the product is called a punch, and the punch is usually installed on the upper die part of the die. A small punch is often called a punch; and the die part used on the outer surface of the molded product is called a die. It is usually installed in the lower die part of the mold. The convex and concave dies are also paired, and only one of them is equally useless.
4, process parts:
Blank or stamping that has been stamped but has not yet been finished.
5, layout:
In a continuous die, the layout of the stamping process on the strip (strip, coil) material, the layout of the final position and the relation between the adjacent parts are described.
6, test die:
Refers to the trial stamping after the mold assembly is completed to check the mold performance and component quality.
7, burr:
The blanking piece section after the sharp edge of the bulge.
8, rebound:
In bending, the change in curvature and angle of the forming part of the die after the external force is removed.
9, wrinkle:
The flange of the drawing member produces a wavy fold.
These are the basic terms that are often heard. Do you have a preliminary idea?
