Description
Technical field
The utility model belongs to automobile lamp and manufactures field, is specifically related to a kind of back light lens mould of plastics exhaust structure.
Background technology
Along with the development of automotive engineering, automobile lamp technology also there occurs change with rapid changepl. never-ending changes and improvements.The design of car light not only needs to ensure that it is functional, must meet the aesthetic standards of consumer, and therefore the structure of car light is designed to be and becomes increasingly complex, and this gives the manufacture of car light, assembling brings no small challenge.
It is also simultaneously appearance member that back light lens is not only functor, and qualified lens can not have any flaw in appearance, can not existing defects in structure, and therefore the manufacture of lens is one of important and difficult issues in car light manufacture process.
Back light lens is generally by PMMA (Chinese name: polymethyl methacrylate, being commonly called as lucite) material injection forms, in injection moulding process, because moulding is complex-shaped, many times injection moulding end is not near die joint, this will cause gas to be enclosed in plastic, causes tired gas, causes a series of adverse consequences, as: increase injection pressure, the defects such as injection moulding is not enough, burn, make moulding tissue looseness, intensity decline, moulding are formed gas line, weld mark etc.
Utility model content
For overcoming the above problems, the utility model provides a kind of back light lens mould of plastics exhaust structure, and its technical scheme is specific as follows:
A kind of back light lens mould of plastics exhaust structure, the dynamic model that described back light lens mould of plastics comprises cover half and coordinates with cover half, is characterized in that:
Insert groove is offered at the injection moulding end of described cover half,
Fixing insert (1) is installed in described insert groove,
Described fixing insert arranges one group of exhaust insert (2) be parallel to each other,
Described fixing insert and one group of exhaust insert be parallel to each other form back light lens mould of plastics exhaust structure.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that:
The described one group exhaust insert be parallel to each other is a pair insert be parallel to each other.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that:
Centered by the geometric center that the end cross section being vented insert is formed, fixing insert is offered steam vent (3), the geometric center that described steam vent is formed with the end cross section of exhaust insert is formed equidistantly radial.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that: described fixing insert and insert groove are fixed by dormant bolt (4), and described dormant bolt is arranged along the bearing of trend of insert groove.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that:
Described steam vent is 1, and 1 described steam vent is parallel to exhaust insert with the line of the geometric center that the end cross section of exhaust insert is formed.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that:
Described steam vent is 2, and 2 described steam vents form isosceles triangular structure with the line of the geometric center that the end cross section of exhaust insert is formed.
According to a kind of back light lens mould of plastics exhaust structure of the present utility model, it is characterized in that:
Described steam vent is 3-7, and the geometric center that 3-7 described steam vent and the end cross section being vented insert are formed forms the convex structure that the geometric center that formed with the end cross section being vented insert is the center of circle.
A kind of back light lens mould of plastics exhaust structure of the present utility model, structure is simple, easy to assembly, can get rid of the gas in die cavity well, eliminates tired gas phenomenon, eliminates the mass defect that plastic causes because of tired gas.
Accompanying drawing explanation
