Description
Technical field
The present invention relates to plastic mould injection manufacture field, specifically a kind of air bag box cover die.
Background technology
Injection mold is a kind of instrument producing plasthetics；Also the work of plasthetics complete structure and accurate dimension it is to confer to
Tool.Injection mold divides into two kinds of thermosetting plastic mould, thermoplastic plastic's mould according to shaping characteristic；Distinguish according to moulding process
For passing mold, blow molding die, draw mould, thermoforming mould, hot-die (compression mould), injection mould etc., wherein hot-die is to overflow
Material mode can be divided into again excessive formula, semi-positive compression, formula of not overflowing three kinds, and injection mould can be divided into again cold flowing mould channel, hot-fluid with running gate system
Road mould two kinds；With by handling mode can be divided into movable type, fixed two kinds.
Mould is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on
On the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model constitutes running gate system and die cavity with cover half Guan Bi, dynamic during die sinking
Mould separates with cover half to take out plastic.
Although the structure of mould due to plastics variety and performance, the shape of plastic and structure and injector type etc. no
Together may be ever-changing, but basic structure is consistent.Mould is mainly by running gate system, thermoregulating system, forming part
Form with constitutional detail.Wherein running gate system and forming part are contact portions direct with plastics, and become with plastics and goods
Change, be the most complicated in mold, change maximum, it is desirable to processing fineness and the highest part of precision.
Summary of the invention
