Mould is a kind of production tool, which can manufacture parts of specified shape and size according to customer requirements. In our daily life, products produced by molds are ubiquitous. About 80% of the objects are made by mold processing, such as plastic basins, water cups, rice cookers, computers, mobile phones, and automobiles. Many parts are produced by molds. of. The mold is powerful and has a wide range of uses, so it has gained the reputation of "mother of industry" and is loved by the majority of users.
1. Definition and types of molds
1. Definition of mold
A mold is an industrial product, made of a specific structure and material. Moulds can mass produce industrial parts with a certain shape and size, ranging from airplanes and automobiles to small nails and screws. Parts produced using molds have the characteristics of high precision, high consistency and high productivity. These advantages are unmatched by any other processing method.
2. Types of molds
The mold determines the quality, efficiency and innovation ability of the product to a large extent. Therefore, the types of molds are also very rich, mainly including the following types:
Drawing die
It is an important equipment to ensure that the covering parts are qualified, and its function is to make the flat wool material into the main space workpiece through the stretching process. The drawing die is divided into two forms, namely, formal and inverted.
Trimming die
It is used to remove excess parts of machined parts, such as the excess outer edges of flat, hollow or three-dimensional parts, so as to prepare for subsequent flanging and forming.
Punching die
It acts on the blank or sheet to separate waste along a closed contour to obtain a punching die with holes.
Flanging die
Its working principle is to flip a part of the semi-finished workpiece to another part of the material, and use the method of stretching to make the edge of the original punched hole form a flange.
Plastic mold
It can press the previously bent or stretched parts into the desired shape through a mold. The shaping mold is a mold that adjusts the size and contour of the semi-finished product to improve product accuracy and surface finish.
2. Introduction and structure of stamping die
1. Introduction of stamping die
Stamping die is a commonly used type of die. Its use method is as follows. Put a metal or non-metallic sheet into the mold at room temperature, and apply pressure to it through a press to separate or deform the sheet. Required parts.
2. The structure of the stamping die
The stamping die is mainly composed of process parts and structural parts. Process parts directly complete the stamping process, that is, direct contact with the material or stamping parts. The structural parts play the role of installation, assembly and guidance in the mold.
