Abstract
The utility model discloses a kind of headlight for vehicles lens rain heat insulation moulds, which is characterized in that including die ontology；Die ontology is cylindrical, and lens raindrop type chamber is arranged inside die ontology；The lens raindrop type chamber semicircular in shape；On the surface of semicircle, setting is distributed the dermatoglyph of irregular raindrop shape；In the lower end of dermatoglyph, stepped ramp type chamber is set；Several heating pipe holes are laterally opened up on die ontology in the top of lens raindrop type chamber；At the top of die ontology, several mounting holes are set；The case where the utility model has technical effect that conventional lenses mold is compared, the lens of the mold production of heating, no entirety fragmentation and fried side, product qualification rate is high, and consistency is good.The micro-structure made by carving machine technique, controllable raindrop is high, and precision is high, and the lens surface finish of production is good, and light form of car lamp gradient meets the requirements.
Description
Technical field
The utility model relates to mechanical device more particularly to a kind of vehicle headlight lens rain heat insulation moulds.
Background technique
Currently manufactured headlight for vehicles lens are mainly based on high borosilicate raindrop lens, and the aspherical of lens has one layer of class
Like the micro-structure of raindrop, the light shape that this feature is mainly used for headlight for vehicles meets the requirement of gradient, is exactly in night meeting
When, the sight of other side driver is than milder, guarantee driving safety.The raindrop lens of high borosilicate material, because refractive index only has
1.470, so the lens diameter size of design is generally above 74, for center thickness 25 or more, lens are big, and materials are more, in heat
When processing, the requirement for temperature is high, if temperature control is bad, is easy to produce fragmentation and fried side.The micro-structure of raindrop, which is used, to be added
The production of work center, curved surface finish is low, and mirror surface requirement is not achieved in roughness, and mold needs repeated multiple times polishing and die trial,
Have an opportunity to meet working condition.Therefore, it is necessary to solve mold raindrop technology with new technique and improve mould structure to control
The method of molding jig temperature.
Utility model content
The purpose of this utility model is according in place of above-mentioned the deficiencies in the prior art, and the utility model aim realizes a kind of vapour
Vehicle headlight lens rain heat insulation mould, which is characterized in that including die ontology；Die ontology is cylindrical, inside die ontology
Lens raindrop type chamber is set；The lens raindrop type chamber semicircular in shape；On the surface of semicircle, setting is distributed irregular raindrop shape
Dermatoglyph；In the lower end of dermatoglyph, stepped ramp type chamber is set；It is laterally opened up on die ontology in the top of lens raindrop type chamber several
A heating pipe hole；At the top of die ontology, several mounting holes are set.
Further, the radius of the lens raindrop type chamber is 40mm-100mm.
Further, the dermatoglyph depth is 0.003mm；The radius of the raindrop is in 0.03mm-0.05mm.
Further, the surface roughness of the stepped ramp type chamber is 0.8；The height 5mm-8mm of stepped ramp type chamber.
Further, the aperture of the heating pipe hole is 10mm-15mm.
The utility model has technical effect that conventional lenses mold is compared, the lens of the mold production of heating, not whole
The case where fragmentation body and fried side, product qualification rate is high, and consistency is good.The micro-structure made by carving machine technique, controllable raindrop
Property it is high, precision is high, and the lens surface finish of production is good, and light form of car lamp gradient meets the requirements.
Detailed description of the invention
Fig. 1 is the half plane view of the utility model.
Fig. 2 is that the utility model looks up direction view.
Fig. 3 is the left view direction cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
In conjunction with shown in attached drawing 1, attached drawing 2, attached drawing 3, a kind of headlight for vehicles lens rain heat insulation mould is present embodiments provided, is wrapped
Include die ontology 1；Die ontology 1 is cylindrical, has simple and practical technical effect；Lens are set inside die ontology 1
Raindrop type chamber 2；2 semicircular in shape of lens raindrop type chamber；Irregular raindrop shape is distributed in the half circular surfaces setting of lens raindrop type chamber 2
Dermatoglyph 3；3 controllability of dermatoglyph for solving raindrop shape is high, and precision is high, and the lens surface finish of production is good, light form of car lamp ladder
Degree, which meets the requirements, waits technical characterstics；In the lower end of dermatoglyph 3, stepped ramp type chamber 4 is set；Primarily to realize the requirement of lens release,
Meet the requirement that positioning is installed inside headlight of lens simultaneously；So stepped ramp type chamber 4 is arranged in the lower end of dermatoglyph 3.Saturating
The top of mirror raindrop type chamber 2 laterally opens up several heating pipe holes 5 on die ontology 1；Using heating tube for mold into
Row heating, so that compared with conventional lenses mold, the lens of the mold production of heating are not whole during manufacturing lens
The case where fragmentation body and fried side, product qualification rate is high, the good feature of consistency, and it is whole broken to solve appearance in manufacture course of products
The case where splitting and frying side.Several mounting holes 6 are set at the top of die ontology 1 and are mainly used for mold installation.
In order to further realize above-mentioned technical characterstic, the radius of lens raindrop type chamber 2 is 40mm-100mm.Dermatoglyph 3 is deep
Degree is 0.003mm；The radius of raindrop is in 0.03mm-0.05mm.The surface roughness of stepped ramp type chamber 4 is 0.8；Stepped ramp type chamber 4
Height 5mm-8mm.The aperture of heating pipe hole 5 is 10mm-15mm.
As the utility model preferred embodiment, it is obvious to a person skilled in the art that the utility model is unlimited
It, can in the details of above-mentioned exemplary embodiment, and without departing substantially from the spirit or essential attributes of the utility model
