By means of injection pressure drift, described second component is expressed in described first component.Subsequently pass through to throw preferably by means of injection pressure drift
Go out the device demoulding that operation makes to make.Such method can effectively and inexpensively manufacture the dress of reflection in an operation
Put.
Preferably coat described second component with the coating of reflected light.Coating procedure here such as can be steamed by vacuum
Send out, spray（Sputtering）, powder coating or the like to be carrying out.As coating material, aluminum such as can be used.
Additionally, specifying in a kind of particularly advantageous design of the present invention, by the coating of described reflection in injection institute
On at least one surface in the corresponding hole being applied to described compression moulding die before stating second component and then by described energy
The injection of material of enough coatings is in described coating.Thus the coating mold filling in compression moulding die in an advantageous manner of described reflection
During be formed on the matrix of described second component.For this reason, before with matrix material filling compression moulding die, by described coating
Material is applied on the surface of described compression moulding die.The coating thus cancelled later includes necessary intermediate steps.Additionally, passing through
Described in the present inventive method can use the such as filling of substantial amounts of material or foaming material, these materials due to exist
Surface defect cannot be coated with traditional painting method.In addition, can be significantly by shaping and the integrated of coating
Reduce operating cost and equipment cost.
Additionally, described task is resolved by a kind of device starting described type, described for this device
One component has that at least one space and/or at least one side are recessed, and described second component is at least partially engaged in described space
And/or during side is recessed.Thus there is highly stable connection between said members upon, because this two components pass through described second
Engagement in the space of described first component and/or side are recessed for the component and be actually engaged with each other together.Thus without
Make the stable extra connecting element of whole device or measure in other words for strengthening described connection, thus described by the present invention
The manufacture of device be simplified and its cost becomes cheap.
Preferably described first component such as vulcanizes polybenzoate by the plastics with higher-strength at least in part（PPS）With/
Or polyphenyl dibutyl carboxylic acid（PBT）Make, wherein said two kinds of polymer ensures individually or in combination described
The necessary stability of device.The material of especially described first component should be the thermoplastic polymer having energy pressure injection, and this gathers
Compound is distinguished by higher strength and stiffness, higher heat-resisting quantity and the good wear-resistant spy of antifriction scrape along
Property.For improving stability further, the material of described first component can extraly be increased with glass fibre and/or mineral
By force.
Described second component is preferably at least partly by transparent plastics such as Merlon（PC）, poly-methyl methacrylate
Ester（PMMA）, cyclic olefine copolymer（COC）And/or cyclic olefin polymer（COP）Make, thus this component is printing opacity and has
There is the surface that can easily and enduringly coat.Due to the processed in many components drape process, described transparent plastics
It should be equally the thermoplastic polymer of energy pressure injection.
Brief description
Exemplarily the present invention is explained in detail below by way of the following drawings.Accompanying drawing is shown below：
Fig. 1 be the perspective by assembly of the invention schematic view and
Fig. 2 is the cross section of the device by Fig. 1.
Specific embodiment
Fig. 1 shows by assembly of the invention 1, and this device 1 includes first structure with higher mechanical stability
Part 2 and a second component 3.Described second component 3 deviates from, at it, the coating 4 being provided with reflection on the surface of first component 2.Described
Coating 4 can be such as the aluminum of vapor plating.Described second component 3 works as minute surface, and described first component 3 is then used as
Support, this support gives described device 1 with necessary stability and in addition can will be stably such as solid for described device 1
It is scheduled on housing.
It can be clearly seen that described first component 2 has space 5, the material engagement of described second component 3 from Fig. 2
To in described space 5, thus there is highly stable connection between described two components 2,3.It is recessed that described space 5 has side
6, described side recessed 6 extraly strengthens anchoring in first component 2 for the described second component 3.
Described such as can be by means of there is the double-component press injector of rotating disk in assembling pressure injection process by assembly of the invention 1
In manufacturing.In the first step, here will be used for the enhanced thermoplastic component of described first component 2 by pressure injection cylinder
It is ejected in compression moulding die and be subsequently allowed to cool.This first thermoplastic component can be such as containing glass fibre
Sulfuration polybenzoate with mineral（PPS）Or the polyphenyl dibutyl carboxylic acid containing glass fibre（PBT）, described sulfuration is poly-
Phenyl ester and polyphenyl dibutyl carboxylic acid correspondingly have the stability of higher machinery and heat, but its coated effect can compare
Poor.In the second step, open described compression moulding die and make to have the die side of described rotating disk and turn to, thus by described the
One component 2 is placed in the second hole.The heat of the non-reinforcing of described second component 3 will be used for by means of pressure injection cylinder in third step
Thermoplastic plastic component is ejected in described second hole.Also flow in the space 5 of described first component 2 and especially in this plastics
Also by way of recessed 6 anchorings in described side there.This second thermoplastic component can be such as non-enhanced Merlon
（PC）, cyclic olefine copolymer（COC）Or cyclic olefin polymer（COP）, these materials can correspondingly coat well, but
There is less heat and machinery stability.
Described second hole here can be equipped with injection pressure drift, can not have warpage and shrinkage depression using this injection pressure drift
In the case of described second thermoplastic component is expressed in described first component 2.After plastics cool down, this drift is used
Dish out device and whole device 1 released from described hole as profile.Described injection pressure drift can be every kind of other
Mirror variations scheme is easily changed in a mold.
Because being difficult to realize described mechanical stability and optical requirement with a kind of plastic type, for by this
At least two different thermoplastic groups are closed in pressure injection technology preferred to corresponding requirement for bright method
Come.It can be described support simultaneously（First component 2）Always using a kind of matrix, here is by corresponding mirror variations scheme
（Second component 3）Pressure injection is in described matrix.Which in turn saves time and the one-tenth for different rack body-compression moulding dies
This.In the case of using expensive optical plastic, again may be by the cost-effective using coming of worthwhile support plastics.Cause
Regularly surrounded for the connection between single component 2,3 and not bonding or clip together, so press this
Bright device has very high stability and intensity, and this especially also functions to positive role in life-time service.
Described being used in principle by assembly of the invention 1 all must be fixed in a defined manner and be bearing in shell
In mirror system in body.Due to the described higher stability by assembly of the invention 1 and relatively more worthwhile manufacturing cost,
So it is particularly suited for use in the mirror system of motor vehicles.
