Abstract
The utility model discloses a kind of quadric injection mould structure of automobile back tail lamp decorative panel, including decorative panel main body, thermoplastic elastomer (TPE) is coated with decorative panel main body, thermoplastic elastomer (TPE) and car body metal plate interference fit, connector is provided with the thermoplastic elastomer (TPE), decorative panel main body inserts the connector of thermoplastic elastomer (TPE), thermoplastic elastomer (TPE) and decorative panel main body injection moulding.The utility model is using first by the injection of decorative panel main part, the lateral section of cooperation is designed as thermoplastic elastomer (TPE), one pair of mould of system is opened in addition, main part is placed in the mould carries out quadric injection mould elastomeric material, the lateral section shaping of cooperation, because elastomeric material is softer, it is possible to achieve the zero clearance with car body metal plate is completely fitted, do not influenceed by car body metal plate accumulated error.
Description
Technical field
The utility model is related to the injection structure of a kind of automobile lamp, particularly automobile lamp.
Background technology
Automobile lamp now, the requirement more and more higher to outward appearance, the requirement to light fixture fit-up gap face difference is also increasingly
Height, does not allow the presence of the visible hole of outward appearance, gap etc..Rear taillight side decorative panel is used as rear bumper and the mistake of car body metal plate
Cross, its fit-up gap is particularly subject to concern, is also a difficult point.
Utility model content
The purpose of this utility model is to provide a kind of quadric injection mould structure of automobile back tail lamp decorative panel, it is to avoid fastness is not
Enough and binding site crack problem.
The concrete scheme that the utility model solves its technical problem is：
A kind of quadric injection mould structure of automobile back tail lamp decorative panel, including decorative panel main body, are coated with decorative panel main body
Thermoplastic elastomer (TPE), thermoplastic elastomer (TPE) and car body metal plate interference fit, are provided with connector on the thermoplastic elastomer (TPE), fill
Tile body inserts the connector of thermoplastic elastomer (TPE), thermoplastic elastomer (TPE) and decorative panel main body injection moulding.
The thermoplastic elastomer (TPE) is 0.3-1mm with the car body metal plate magnitude of interference.
The thickness of the decorative panel main body is 1-1.5mm, the thermoplastic elastic body thickness 0.3-0.5mm.
Using first decorative panel main part is molded, the lateral section of cooperation is designed as thermoplastic elastic to the utility model
Body, opens one pair of mould of system in addition, and main part is placed on carries out quadric injection mould elastomeric material, the side of cooperation in the mould
Part is molded, not tired by car body metal plate because elastomeric material is softer, it is possible to achieve the zero clearance with car body metal plate is completely fitted
The influence of product error.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Specific embodiment
It is described in further detail to of the present utility model below in conjunction with the accompanying drawings, but protection domain of the present utility model
It is not limited to the embodiment.
Such as Fig. 1, a kind of quadric injection mould structure of automobile back tail lamp decorative panel, including decorative panel main body 1, decorative panel main body 1
On be coated with thermoplastic elastomer (TPE) 2, thermoplastic elastomer (TPE) 2 and the interference fit of car body metal plate 3 set on the thermoplastic elastomer (TPE) 2
Connector 4 is equipped with, decorative panel main body 1 inserts the connector 4 of thermoplastic elastomer (TPE) 2, thermoplastic elastomer (TPE) 2 and decorative panel main body 1
Injection moulding.Thermoplastic elastomer (TPE) 2 is 0.3-1mm with the magnitude of interference of car body metal plate 3.The thickness of decorative panel main body 1 is 1-1.5mm,
The thickness 0.3-0.5mm of the thermoplastic elastomer (TPE) 2.
The material of decorative panel main body 1 uses ABS or PP, and main body opens the secondary mould of system one, and first injection completes this part.Coordinate
Lateral section is designed as thermoplastic elastomer (TPE) 2, and one pair of mould of system is opened in addition, and decorative panel main body 1 is placed in the mould to be carried out
Quadric injection mould elastomeric material, the lateral section shaping of cooperation.The material of thermoplastic elastomer (TPE) 2, generally TPE, TPV, EPDM etc..
Elastomeric material is softer, it is possible to achieve the zero clearance with car body metal plate 3 is completely fitted, not by the shadow of car body metal plate accumulated error
Ring.In decorative panel main body 1 and the binding site of thermoplastic elastomer (TPE) 2, the treatment of the dermatoglyph of decorative panel main body 1, to increase bonded area, increases
Strong binding strength.The structure can avoid the occurrence of the problem of crack and intensity difference.
