Abstract
The utility model discloses a kind of optical telescopic sleeves, including sleeve body, notch cuttype through hole is equipped with inside the sleeve body, the notch cuttype through hole includes the large diameter hole below diameter holes and diameter holes, single channel is equipped between the internal diameter and outer diameter of the sleeve body, the junction of the single channel and diameter holes is glue-feeder, it is characterized by: the sleeve body end face is equipped with c-type air discharge duct, the c-type air discharge duct surrounding is vertically equipped with several "-" type air discharge ducts, and the diameter holes sidewall periphery is equipped with annular empty avoiding section.The utility model compared with prior art the advantages of be: the arrange in pairs or groups c-type air discharge duct of sleeve body end face of single channel realizes that whole circle is vented, the empty avoiding section of diameter holes periphery further increases exhaust, the bad problem of exhaust caused by entirety improves mold due to long-time heating produces, guarantees to produce the validity of product and the precision of die joint.
Description
Technical field
The utility model relates to optical element technology field, in particular to a kind of optical telescopic sleeves.
Background technique
Sleeve generally applies to optical mould and the group of mode is closed, and is primarily adapted for use in production high-order mobile lens, vehicle-mounted
The important cores spare part such as camera lens and optical mirror slip, optical telescopic sleeve vent groove configuration design commonly used in the prior art is unreasonable,
Exhausted range is too small, it is easy to cause the hot gas generated after heating discharge to be obstructed, be trapped in inside tube-in-tube structure, to influence
The validity of product and the precision of die joint are produced, causes product bias unstable.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, provide can integrally improve mold because it is long when
Between heating production and caused by the bad problem of exhaust, to guarantee the concentricity of sleeve and a kind of optical telescopic sleeve of concentricity.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of optical telescopic sleeve, including sleeve sheet
Body, the sleeve body inside are equipped with notch cuttype through hole, and the notch cuttype through hole includes below diameter holes and diameter holes
Large diameter hole is equipped with single channel, the junction of the single channel and diameter holes between the internal diameter and outer diameter of the sleeve body
For glue-feeder, the sleeve body end face is equipped with c-type air discharge duct, and the c-type air discharge duct surrounding is vertically equipped with several words
Type air discharge duct, the diameter holes sidewall periphery are equipped with annular empty avoiding section.
As an improvement, the c-type air discharge duct both ends are close to single channel.
As an improvement, the "-" type air discharge duct is evenly distributed on c-type air discharge duct surrounding.
The utility model compared with prior art the advantages of be: single channel collocation sleeve body end face c-type air discharge duct
Realize whole circle exhaust, the empty avoiding section of diameter holes periphery further increases exhaust, and the whole mold that improves is due to long-time heating produces
Caused by the bad problem of exhaust, guarantee the validity of production product and the precision of die joint.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of optical telescopic sleeve of the utility model.
Fig. 2 is a kind of top view of optical telescopic sleeve of the utility model.
Fig. 3 is that a kind of the utility model optical telescopic sleeve cuts open figure.
It is as shown in the figure: 1, sleeve body, 2, diameter holes, 3, large diameter hole, 4, single channel, 5, glue-feeder, 6, c-type air discharge duct,
7, "-" type air discharge duct, 8, empty avoiding section.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing 1,2,3, a kind of optical telescopic sleeve, including sleeve body 1 are equipped with ladder inside the sleeve body 1
Type through-hole, the notch cuttype through hole include the large diameter hole 3 of diameter holes 2 and the lower section of diameter holes 2, the sleeve body 1 it is interior
Single channel 4 is equipped between diameter and outer diameter, the junction of the single channel 4 and diameter holes 2 is glue-feeder 5, the sleeve sheet
1 end face of body is equipped with c-type air discharge duct 6, and 6 surrounding of c-type air discharge duct is vertically set there are three "-" type air discharge duct 7, three words
Type air discharge duct 7 and single channel 4 are mutually 90 degree of angles, and 2 sidewall periphery of diameter holes is equipped with annular empty avoiding section 8, annular empty avoiding
Section 8 is cavity structure, extends to the other end from 2 one end of diameter holes.
6 both ends of c-type air discharge duct are close to single channel 4.
The "-" type air discharge duct 7 is evenly distributed on 6 surrounding of c-type air discharge duct.
In the specific implementation, the face PL of sleeve body is expanded than existing structure considerably increases exhaust to the utility model,
Being conducive to discharge improves generated gas after eyeglass molding, and assembly mode enters son among notch cuttype through hole, diameter holes surrounding
Empty avoiding section can increase exhaust, and not influence to assemble, and original structure sleeve needs to enter with mode after processing every time
Match in fact, increases task difficulty, and take a long time.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
