Description
Technical field
The present invention relates to plastic mould to be molded manufacturing field, specifically a kind of air bag box cover die.
Background technology
Injection mold is a kind of instrument for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Instrument.Injection mold divides into two kinds of thermosetting plastic mould, thermoplastic plastic's mould according to shaping characteristic；Distinguished according to moulding process
To pass mold, blow molding die, draw mould, thermoforming mould, hot-die (compression mould), injection mold etc., wherein hot-die is in a manner of flash
Excessive formula, semi-positive compression, three kinds of formula of not overflowing can be divided into again, injection mold can be divided into two kinds of cold flowing mould channel, hot runner mould with running gate system again；
So that portable, fixed two kinds can be divided into by handling mode.
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, cover half peace
On the fixed form of injection (mo(u)lding) machine.In injection moulding, dynamic model forms running gate system and die cavity, die sinking with cover half closure
When dynamic model and cover half separation to take out plastic products.
Although the structure of mould is due to plastics variety and performance, the shape of the plastic products and type of structure and injector
May be ever-changing Deng different, but basic structure is consistent.Mould is mainly by running gate system, thermoregulating system, shaping zero
Part and constitutional detail composition.Wherein running gate system and forming part be with the direct contact portion of plastics, and with plastics and product and
Change, it is most complicated in mold, change is maximum, it is desirable to processes finish and precision highest part.
The content of the invention
It is an object of the invention to provide a kind of air bag box cover die, is by a kind of virtual number of air bag box cover die
According to 3D moulding, solid modelling type frame mould is processed into, mould solid modelling type inframe is molded into by injection machine, realizes 3D void
Intend data moulding and be changed into entity products, for automobile industry.
To achieve the above object, the present invention provides following technical scheme：

Put, rational deployment fortune water cooling, avoid 3D molded product modifications；
2) 3D moulding optimal depanning direction is adjusted, it is few greatly to define master mold male model steel material, is asked after thickness with 3D moulding
Difference, then by first point of improvedd 3D moulding parting line, forge poor line and design die joint, draw single case mold frame, male model
Type frame；
3) weight of 3D moulding and the injection amount of injection machine are calculated, the size and mold base size of injection machine is defined, uses
TOP-TIP, reduction cold burden, which enters in product, influences product appearance；
4) by case mold frame and male model type frame, good ejection is laid out, imports fortune water cloth office during mold flow analysis；
5) exhaust is designed in product border, optimization processing technology, the sunykatuib analysis of each motion parts on mould；
6) completed after each parts of mould are finished by accurate mechanical equipment, machining tolerance is in positive and negative 0.02mm scopes
It is interior, detect laggard luggage and match somebody with somebody, then die trial injection molding draws entity 3D molded products；
7) product is that two caves are the right mirrors of a first from left, is set as long as improving a cave product in design process with mould
Count, then carry out mirror, ensure all pushing methods of mould, exhaust mode, enter glue mode, product clamp,
It is the same to forge poor line.
As further scheme of the invention：Bad problem in step 1) includes the unequal caused contracting of wall thickness
Water, thickness print, outward appearance weld bond, glue position depanning angle, the thin steel of sharp steel, 3D moulding parting line and the poor line of forging.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by a kind of virtual number of air bag box cover die
According to 3D moulding, R ＆ D design is processed into solid modelling type frame mould, and mould solid modelling type inframe is molded into by injection machine,
Realize that 3D virtual data moulding is changed into entity products, for automobile industry.
