Penetrate moulding process.
Background technology
Decorative in the manufacturing field of automobile interior exterior decorations, lightweight and environmental protection are the trend of its development.In order to realize this
The novel environment friendlies surface decoration tech such as a target, in-mold decoration starts to occur, and the environmental protection such as fretting map lightweight production method is also opened
Begin to apply.
A kind of existing technology is that mould embeds film injection molding process.The technological process includes：Design model pattern, printing
PET film；Film is subjected to hot pressing according to product shape, is cut；Film after molding is put into cavity, is determined using vacuum suction
Position；Molding, is molded, figure line is transferred to product surface；Cooling die sinking, takes out product.Mould embeds film injection molding process can
It is great decorative and functional to realize injection molding, decoration integrated and a variety of different special-effects can be made,
But the technology the problem is that：Product weight is increased, increases 0.1-2mm film layers；Injection molding process window is small, injection
When being molded, since film and ink high temperature resistant time are short, high temperature and pressure is needed to be molded, but high temperature and pressure can lead to red ink,
The impact force to sheet material can be increased, lead to film displacement and red ink.
Existing another technology is low-pressure structure foaming lightweight environment-protective process.The technological process is：It is noted in plastics
Before penetrating, low-pressure gas is squeezed into the die cavity of sealing by nitrogen ancillary equipment and inhibits foaming agent immediate effervescence, when pressure reaches
Start by gas vent slowly to discharge the nitrogen in mold during to 0.8-2.0MPa, while by a certain amount of (not filling die cavity)
Plastic melt (containing foaming agent) injects die cavity, and foaming agent, which decomposites the gas come, makes plastic expansion full of die cavity, forms hair
Bubble.Low-pressure structure foaming lightweight environment-protective process belongs to chemical blowing process, remains many advantages of conventional injection molding technique,
The segmental defect of the latter is in turn avoided, as product strength is inadequate, the production cycle is too long, molding rate is low.Using constructional foaming skill
Art can significantly be mitigated the weight molding large the part with complicated structure of product, can be operated simultaneously using inexpensive mold, multimode cavity, so as to
Reduce production of articles cost.Constructional foaming product is a kind of disjunctor expanded material with dense skin, Unit Weight intensity
It is 3~4 times high with rigidity ratio unexpanded material of the same race.But the technique the problem is that：During injection, due to the diffusion speed of gas
Degree quickly, can cause the rough surface of product, influence the beauty of product, it is impossible to be used in appearance member；At present, there has been no more ripe
Auxiliary process means are solved the problems, such as incrustation.
According to the above, mould embeds film injection molding process and low-pressure structure foaming lightweight environment-protective process exists respectively
From advantage and shortcoming, therefore provide and a kind of have both lightweight and the injection molding technique of decoration function is necessary.
