Description
Technical field
The present invention relates to the injection molding technology fields of automobile interior decoration, and in particular to a kind of double-shot moulding side of vehicle internal decoration seat armrest
Method.
Background technique
The mainly common injection molding of existing vehicle internal decoration seat armrest injection moulding process, is also named monochromatic injection molding, this method passes through high temperature
High pressure injects plastic pellet pressure maintaining in mold after injection molding handrail melting sources and is cooled and shaped.This injection moulding process is simpler
Single, manufactured handrail product shape is also relatively simple.But people are to requirements such as the performances, appearance, feel of vehicle internal decoration seat armrest
Higher and higher, originally the vehicle internal decoration seat armrest of this single shape, feel is not in the requirement for being satisfied with client's harshness.
In recent years, with the development of domestic and international Injection Industry, Some Domestic automobile interior decoration producer is in severe living environment
Under, develop one after another towards special two-Color part, wherein the double-shot moulding technology of vehicle internal decoration seat armrest is exactly a kind of to meet visitor
The higher demand in family and market and research and develop.
So-called double-shot moulding, Gu Mingsi meaning is exactly one kind by two kinds of plastic melts or otherwise identical plastic but different colours
Two kinds of melt injection moldings form a kind of product, make the table of product, inner be made of " difference " plastic cement.It is mainly used for meeting product
The requirement such as performance, appearance, feel is that a kind of market potential is very big, new technique forming method.
Summary of the invention
In order to solve not to be able to satisfy client and market to automobile armrest performance, appearance, feel etc. due to existing injection moulding process
It is required that shortcoming, the present invention provides a kind of double-shot molding method of vehicle internal decoration seat armrest, and not only process is simple, suitable for this method
Industrial application is closed, and vehicle internal decoration seat armrest can be molded simultaneously, substantially reduces the process time, improves technique effect
Rate.
In order to achieve the above objectives, the technical solution of the present invention is as follows:
The double-shot molding method of vehicle internal decoration seat armrest of the invention, comprising the following steps:
A, first the first injection raw material is heated and is melted, then the first injection raw material of liquid melted passed through defeated in injection-moulding device
It send in mold cavity I of the device I conveying through hot flow path injection handrail substrate, after pressure maintaining and cooling, forms handrail substrate, die sinking
Afterwards, the handrail substrate of injection molding is removed and placed in quadric injection mould position；
B, while the first injection raw material is melted in heating, another group of heating device is in heating fusing and the first injection raw material color
The second different injection raw materials is opened in first time and removes and places the handrail substrate of injection molding in quadric injection mould
Behind position, the second injection raw material of liquid melted is put by the conveying device II conveying in injection-moulding device through hot flow path injection
It is equipped in the mold cavity II of the handrail substrate formed by the first injection raw material；By pressure maintaining and cooling, it is formed in the first injection molding
The elastomer that the second injection raw material is coated on the handrail substrate that raw material is formed completes the molding manufacture of entire handrail.
Further, in the step A, the speed of injection molding is 40-50mm/s, the pressure of pressure maintaining is 45-55Kgf, time
For 4.5-5.5s；Cooling temperature be 40-50 DEG C of cover half, 35-45 DEG C of dynamic model, time 70-80s.
Further, in the step B, the speed of injection molding is 55-65mm/s, and the pressure of pressure maintaining is 45-55Kgf, time
For 3.5-4.5s；Cooling temperature be 40-50 DEG C of cover half, 35-45 DEG C of dynamic model, time 45-55s.
Further, the conveying device I and conveying device II is screw-rod structure.
Further, first injection raw material is ABS, and second injection raw material is TES.
In order to enable product to press tighter with second of injection molding material when forming for second, to have the function that sealing, note
When modeling, the handrail substrate size of the first time injection molding can be than the handrail size of second of injection molded actually required
It is bigger.
The invention has the benefit that
In the present invention, because the contractibility of double-shot moulding is affected to product structure size, therefore the ebonite of first injecting products
Part, i.e. the first injection raw material are hard ABS injection raw material, mainly play skeletal support；The flexible glue part of injecting products again,
That is the second injection raw material is TES injection raw material, main to clad ABS skeleton.Because flexible glue is easily-deformable, with the ABS of first time injection molding
Guarantee the smallest deformation quantity.
A kind of double-shot molding method of vehicle internal decoration seat armrest of the present invention is not only high-efficient, is suitble to industrial application, together
The principles and policies of the corresponding environment-friendly type production of Shi Zuowei, double-shot moulding can extremely significantly improve product qualification rate, to reduce
The generation of waste, save the cost earn a profit.And compound back bar is all coated no less than corium in terms of color, feel.
Entire simple process, it is easy to accomplish.
