Secondary injection molding, production cycle length；（4）Two molds produce, and the gate materials of generation are more.
The content of the invention
The object of the present invention is to provide a kind of mold for injection molding of double-colored automotive upholstery, it has, and cost is relatively low, imitates
The characteristics of rate is higher.The invention also discloses a kind of mold for injection molding of double-colored automotive upholstery.
First technical solution of the present invention be：
The mold for injection molding of double-colored automotive upholstery, the double-colored automotive upholstery include the transparent area and position positioned at left part
Separated between the shading region of right part, the transparent area and shading region by a product interface, the double-colored automotive trim
The mold for injection molding of part comprises the following steps：
1）Choose mould, which includes the left chamber of shaping transparent area and right chamber for being molded shading region, the left chamber and
Right chamber is separated by a cavity-bounding surface, and the thick chamber for being more than the right chamber of chamber of the left chamber is thick, and the left chamber and right chamber are mutual
Perforation, meanwhile, the top of the left chamber is equipped with right feeding-passage equipped with left feeding-passage, the top of the right chamber；
2）Light raw material is injected into the left chamber by the left feeding-passage, meanwhile, by the right feeding-passage to the right side
The dark raw material of intracavitary injection；And
The left chamber and the respective volume of the right chamber are calculated, according to the size of volume, the charging for adjusting the left feeding-passage is fast
The charging rate of degree and the right feeding-passage, makes the left chamber and the right chamber are synchronously full of by corresponding raw material.
The light color raw material is close with the physical property of dark raw material.
Second technical solution of the present invention be：
The mold for injection molding of double-colored automotive upholstery, the double-colored automotive upholstery include the transparent area and position positioned at left part
Separated between the shading region of right part, the transparent area and shading region by a product interface, the double-colored automotive trim
The mold for injection molding of part includes the left chamber of shaping transparent area and the right chamber for being molded shading region, and the left chamber and right chamber pass through one
Cavity-bounding surface is separated, and the thick chamber for being more than the right chamber of chamber of the left chamber is thick, and the left chamber and right chamber are mutually communicated, meanwhile,
The top of the left chamber is equipped with left feeding-passage, the top of the right chamber is equipped with right feeding-passage.
The invention has the advantages that compared with the prior art,：Cost is relatively low, efficiency is higher.The double-colored automobile of the present invention
Original two mold is changed to one set of die injection by the mold for injection molding of inside gadget, and it is double that removing requires production equipment to possess
Outside gun barrel, other require consistent with monochromatic mould, and do not have interaction requirement to mould, reduce mould processing charges.
Meanwhile simplify production stage, it is only necessary to which an injection molded, shortens the production cycle, can effectively improve production efficiency, shows
Write the economic benefit for adding injection factory.

Embodiment
Embodiment 1
The mold for injection molding of double-colored automotive upholstery, is used to prepare the double-colored inside gadget such as automobile button.
As shown in Figure 1, which is included positioned at the transparent area 11 of left part and positioned at the shading region 12 of 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.For example the transparent area 11 is used for radium-shine character occur, which is used to install indicator light.
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 thick chamber for being more than the right chamber 102 of the chamber of the left chamber 101 is thick, and the left chamber
101 and right chamber 102 be mutually communicated.That is, the wall thickness of the transparent area 11 of the left chamber 101 preparation is more than screening prepared by the right chamber 102
The wall thickness in light area 12.Meanwhile the top of the left chamber 101 is equipped with left feeding-passage 1011, the top of the right chamber 102 is equipped 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 mold for injection molding of double-colored automotive upholstery comprises the following steps：
1）Choose mould 100.So-called selection, is not only included in storehouse the mode such as take, can also necessarily include preparing
The mode of the mould 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 102 respective volume of right chamber are calculated, according to the size of volume, adjusts the left feeding-passage
The charging rate of 1011 charging rate and the right feeding-passage 1021, makes the left chamber 101 and the right chamber 102 by corresponding raw material
Synchronously it is full of.For example the volumetric ratio of the left chamber 101 and the right chamber 102 is 2:1, then the charging rate of the left feeding-passage 1011
Charging rate ratio with the right feeding-passage 1021 should be 1:2, filled out at the same time so as to reach the left chamber 101 and the right chamber 102
It is full.Wherein, so-called charging rate, refers to entering corresponding cavity in the unit interval（Including left chamber and right chamber）Interior raw material
Amount.
Optimization：
Light raw material used is close with the physical property of dark raw material.For example light raw material is using PC2047 whites material, dark color
Raw material uses PC2045 black materials.It so, it is possible to realize light raw material and dark raw material mutually melting at product interface o
Close.
In conclusion original two mold is changed to one by the mold for injection molding of the double-colored automotive upholstery of the present invention
Mold is molded, and does not have interaction requirement to mould, reduces mould processing charges.Meanwhile production stage is simplified, shorten
Production cycle, production efficiency can be effectively improved.
The foregoing is merely the preferred embodiment of the present invention, is not intended to limit the scope of the invention, every utilization
The equivalent structure or equivalent flow shift that description of the invention and accompanying drawing content are made, it is related to be directly or indirectly used in other
Technical field, be included within the scope of the present invention.
