Embodiment
Embodiment 1
The mold for injection molding of double-colored automotive upholstery, for preparing the double-colored inside gadget such as automobile button.
As shown in Figure 1, the double-colored automotive upholstery includes the transparent area 11 positioned at left part and the shading region 12 positioned at right part,
Separated between the transparent area 11 and shading region 12 by a product interface o.Obviously, product interface o is virtual boundary
Face.Such as, the transparent area 11 is used for radium-shine character occur, and the shading region 12 is used to install indicator lamp.
With reference to shown in Fig. 2, the mold for injection molding 100 of the double-colored automotive upholstery includes the left chamber of shaping transparent area 11
101 and for being molded the right chamber 102 of shading region 12.The left chamber 101 and right chamber 102 are separated by a cavity-bounding surface o '.
Obviously, cavity-bounding surface o ' is also virtual interface.The chamber thickness of the left chamber 101 is thick more than the chamber of the right chamber 102, and the left chamber
101 and right chamber 102 be mutually communicated.That is, the wall thickness of transparent area 11 prepared by the left chamber 101 is more than screening prepared by the right chamber 102
The wall thickness in light area 12.Meanwhile, top of the top provided with left feeding-passage 1011, the right chamber 102 of the left chamber 101 is provided with right charging
Passage 1021.That is, original technology is substituted by the way of a mould to prepare double-colored automotive upholstery using two molds
Mode.
Embodiment 2
The injection molding method of double-colored automotive upholstery comprises the following steps：
1）Choose mould 100.It is so-called to choose, the mode such as take is not only included in storehouse, can also necessarily include preparing the mould
The mode of tool 100.The mould 100 uses the mold for injection molding 100 of the double-colored automotive upholstery described in embodiment 1.
2）Light raw material is injected into the left chamber 101 by the left feeding-passage 1011, meanwhile, pass through the right feeding-passage
1021 inject dark raw material into the right chamber 102.
More specifically：
The left chamber 101 and the respective volume of right chamber 102 are calculated, according to the size of volume, the left feeding-passage 1011 is adjusted
The charging rate of charging rate and the right feeding-passage 1021, makes the left chamber 101 and the right chamber 102 synchronously be filled by corresponding raw material
It is full.Such as, the volumetric ratio of the left chamber 101 and the right chamber 102 is 2:1, the then charging rate of the left feeding-passage 1011 and the right side
The charging rate ratio of feeding-passage 1021 should be 1:2, so as to reach the left chamber 101 and the right chamber 102 by while filling up.Its
In, so-called charging rate refers to entering corresponding cavity in the unit interval（Including left chamber and right chamber）Interior material quantity.
Optimization：
Light raw material used is close with the physical property of dark raw material.Such as, light raw material is using PC2047 whites material, dark raw material
Using PC2045 black materials.It so, it is possible to realize the mutual fusion of light raw material and dark raw material at product interface o.
In summary, original two mold is changed to one by the injection molding method of double-colored automotive upholstery of the invention
Mold is molded, and does not have interaction requirement to mould, reduces mould processing charges.Meanwhile, production stage is simplified, is shortened
Production cycle, production efficiency can be effectively improved.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
