Description
Technical field
The utility model belongs to a kind of product design and is processed with mould processing technology structure more particularly to optical ball cover.
Background technology
Band cylindrical optical ball cover described in the utility model is used in spherical camera for protecting camera lens and participation
Otherwise the injection molding optical ball cover of imaging, the spherical surface of traditional ball cover will produce injection molding back-off phenomenon, taken the photograph to expand no more than hemisphere
The field angle of camera imaging and region can increase cylinder connection, and by optical manufacturing, the cylinder section of ball cover can also be used for into
Picture.As shown in Figure 1, 2, ball cover outer surface carries out transition by spherical outside surface 41a and outer cylinder 41b in a manner of tangent, and composition is entire
Product external surfaces, ball cover inner surface carry out rounding off, ball cover 4 by ball inner surface 42a and column inner surface 42b in a manner of tangent
Perspective plane be complete disc, the optical surface of the spherical surface of surfaces externally and internally and cylinder partial composition ball cover, there is a flange in bottom surface
Side 44 is used for the assembly of optical ball cover.Flange includes that upper surface, baseplane and outer ring height face are Non-optical surfaces.
We have found that ball cover spherical diameter is D in manufacturing process, and ball cover cylinder height H works as 0.4D>H>When 0.15D,
It is molded in melt filling process, as melt gradually extends to the climbing stroke of spherical surface top-direction, this section is to spherical surface top side
Filling can not be completed before bottom border melt is closed to filling melt, make the air in die cavity that can not be completely exhausted out, slight
There can be optical imagery performance after molding not reaching requirement, it is serious, molding trapped gas phenomenon is will produce, or even burn optics
Finished surface.Since such case can not accurately be expected in the design process, the especially requirement of optical property only exists
Production is out rear or needs to be detected using special instrument, could find.It molds figure as shown in figure 3, a kind of
Solution is：Punch insert height carries out drop surface treatment, for example declines 0.1, and ball cover optics area entirety wall thickness increases, wherein ball
Wall thickness will increase to 0.1 at the top of face, improve plastic melt mobility when molding.And above-mentioned ball cover is due to inner surface whole
For optical manufacturing face, punch insert can only be adjusted when adjusting making mold.Since the casting area of punch insert is optical manufacturing face, system
Make of high cost, very big extension process time, and increases considerably processing cost.
Invention content
The problem of the purpose of the utility model is to overcome existing band cylindrical optical ball cover casting process, provides one
Band cylindrical optical ball cover of the kind with technique step structure is to reduce production difficulty and production cost.
Technical solution used by the utility model is a kind of band cylindrical optical ball cover, and ball cover outer surface is by spherical outside surface and outside
Cylinder carries out transition in a manner of tangent, and with the entire product external surfaces of composition, ball cover inner surface is by ball inner surface and column inner surface
Rounding off is carried out in a manner of tangent, is characterized by, and the end of column inner surface is machined with the work that internal diameter is more than column inner surface
Skill step forms entire product inner surface with ball inner surface and column inner surface, and the internal diameter of technique step is bigger 0.1- than column inner surface
0.3mm, the optical surface of the spherical surface and cylinder partial composition ball cover of surfaces externally and internally, flange includes baseplane and inside and outside height face
It is Non-optical surfaces, is used for the assembly of optical ball cover.
The utility model is improved to existing band cylindrical optical ball cover, in the end of column inner surface（I.e. in flange
Surface）It is machined with the technique step that internal diameter is more than column inner surface.Since existing flange bottom surface, upper surface and outer peripheral surface are equal
For Non-optical surfaces, even inner surface optical surface is also not practical, so technique step be designed to it is non-optical
Surface can play the role of reducing optical surface working (finishing) area instead not only without the optical property of the original ball cover of reduction, to reduce
Production difficulty and production cost can be by solid and technique step is designed to that Non-optical surfaces can be by the fixation ring forming in mold
The counter structure for determining ring carries out drop surface treatment, and ball cover optics area entirety wall thickness increases, and improves plastic melt mobility when molding.
Realize the adjustability of mold.
The height of technique step is equal with the height of flange.It, can be in the case where not influencing the optical property of ball cover
To greatest extent reduce ball cover inner surface optical manufacturing area and retain it is maximum face height drops, for the later stage adjust.
The utility model increases a technique step in Design Stage, in the injection mould processing stage, using solid
The mode for determining one hanging platform of increase on ring, realizes the adjustability of mold.It is small to existing product change, since there are process areas
Rank makes mould be provided with adjustable space, can be conveniently by adjusting mold to make up the insufficient problem of design, while utilizing non-light
Regulating object of the fixed ring of structure as entire mold is learned, re-working for optical surface is avoided, processing can be reduced to greatest extent
Cost and time ensure product quality.

Specific implementation mode
The following examples can make professional and technical personnel more understand the utility model, be repaiied to following implementation
Change, it is possible to add and replace all, all without departing from the scope of protection of the utility model.
As Figure 4-Figure 6, the utility model is a kind of band cylindrical optical ball cover, is changed to existing band cylindrical optical ball cover
Into retaining the design of all opticators of existing product, ball cover outer surface is by spherical outside surface 41a and outer cylinder 41b with tangent
Mode carries out transition, forms entire product external surfaces, ball cover inner surface is by ball inner surface 42a and column inner surface 42b with tangent
Mode carries out rounding off, except that the end of column inner surface 42b is machined with the technique step that internal diameter is more than column inner surface
45, entire product inner surface is formed with ball inner surface 42a and column inner surface 42b, spherical surface and the cylinder partial of surfaces externally and internally form
The optical surface of ball cover, flange 44 are Non-optical surfaces including upper surface, baseplane and inside and outside height face, are used for optical ball
The assembly of cover, the height of technique step is equal with the height of flange, and technique step is also Non-optical surfaces.Technique step it is interior
Diameter is bigger 0.1-0.3mm than column inner surface, and such as the ball cover a diameter of 50mm of the lowermost cylinder, then the internal diameter of technique step is 50.1-
50.3mm。
The mold of the utility model is improved on a kind of existing mold foundation with cylindrical optical ball cover, by cavity plate
1, punch insert 2 and fixed ring 3 form, and cavity plate remains unchanged, and punch insert cylinder partial height becomes short, and main change is to fix
Ring increases technique step of the circle hanging platform 33 for matching synthesis type ball cover with punch insert on original fixed ring upper surface
45。
Remaining not described part is same as the prior art.
