Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It is understood that
Specific embodiment described herein is used only for explaining the utility model, rather than the restriction to the utility model.In addition it also needs
It is noted that illustrating only part relevant to the utility model for ease of description, in attached drawing and not all.
Referring to fig. 2 to Fig. 6, the utility model embodiment provides a kind of anti-iridescence structure of lens, including is molded for the first time
Red part 1, be molded for the second time black part 2 and third time be molded white part 3, i.e., injection molding when, be first molded red part 1, be molded again black part 2,
Finally it is molded white part 3.
Red part 1 includes the first noumenon portion 11, and the backgauge portion 12 of protrusion, backgauge portion 12 are arranged on the side wall in the first noumenon portion 11
Step 13 is formed between the first noumenon portion 11；Black part 2 includes the second body part 21, is arranged on the side wall of the second body part 21 convex
Platform 22, boss 22 are matched with step 13；White part 3 covers the second body part 21, backgauge portion 12 and the first noumenon portion 11.
When being molded white part 3, the flow direction of the melt of white part 3 is as shown in arrow in Fig. 3 and Fig. 4.When the melt of white part 3
During the junction by black part 2 and red part 1 is flowed, the material of backgauge portion 12 is melted and is brought into red part 1, simultaneously will
The material of black part 2 melts and the material of black part 2 is driven to fill up the part that backgauge portion 12 flows away, so that making the material of black part 2 cannot flow into
In red part 1, lens iridescence is solved the problems, such as.
The setting of boss 22, the flowing for the material of backgauge portion 12 provide support；In white 3 injection moulding process of part, backgauge portion 12
It is gradually reduced, after the completion of injection molding, the space of part backgauge portion 12 is hacked the substitution of part 2, passes through backgauge portion between black part 2 and red part 1
12 and the junction of second junction of body part 21, boss 22 and step 13 have a common boundary, the material of black part 2 may not flow into red part 1
It is interior, improve the quality of production.
Step 13 includes the first wall 131 connecting with the first noumenon portion 11 and the second wall 132 connecting with backgauge portion 12, and
It is arranged between one wall 131 and the second wall 132 in angle.Angle between first wall 131 and the second wall 132 is 70 °~110 °.When
When angle between first wall 131 and the second wall 132 is 90 °, step 13 is L shape step.Boss 22 includes pasting with the first wall 131
The third wall 221 of conjunction and the 4th wall 222 being bonded with the second wall 132.
In the present embodiment, the angle between the first wall 131 and the second wall 132 is 100 °, the first wall 131 and the first noumenon
The surface in portion 11 is parallel, and the second wall 132 is obliquely installed relative to the first wall 131 to the direction close to the first noumenon portion 11, increases
The contact area of black part 2 and red part 1, so that black part 2 and the connection of red part 1 are stronger.Therefore, the 4th wall 222 is relative to
Three walls 221 are obliquely installed to the direction far from the second body part 21.
Backgauge portion 12 is in rectangle, backgauge portion 12 with a thickness of 0.8mm~1.2mm, the length of backgauge portion 12 be 6mm~
10mm.The backgauge portion 12 of rectangle, production easy to process.The size of backgauge portion 12 is mainly by the temperature and speed of the melt of white part 3
Degree determines.When being molded white part 3, by the melt injection type chamber of white part 3, melt has specified injection moulding speed.When melt flow to it is black
When the intersection of part 2 and red part 1, temperature and speed when temperature possessed by melt and speed have just been launched into type chamber with melt have
Institute is different.Here, temperature related with the size of backgauge portion 12 and speed refer to when melt flow to the boundary of black part 2 and red part 1
When place, temperature and speed possessed by melt.
As shown in figure 5, the thickness of backgauge portion 12 is indicated with T, the length of backgauge portion 12 is indicated with L.The thickness of backgauge portion 12
Size and the size of temperature of melt of white part 3 be positively correlated setting.The temperature of general melt is higher, then backgauge portion 12 is arranged
Thickness T it is bigger.In the present embodiment, when melt temperature is 220 DEG C, thickness T is 0.8mm；When melt temperature is 230 DEG C
When, thickness T is 0.9mm；……；Melt temperature is every to increase by 10 DEG C, and thickness T increases 0.1mm.Certainly, herein only to backgauge portion
12 thickness setting proposes a kind of reference mode, is not construed as limiting, can be arranged according to actual needs.
The size of the speed of the melt of the size of the length of backgauge portion 12 and white part 3 is positively correlated setting.That is backgauge portion 12
Length size and melt to flow through black part 2 related with the flow velocity of intersection of white part 3.If the speed of melt is specified less than 50%
Injection speed, then length L value 6mm~8mm；If the speed of melt is not less than 50% nominal injection speed, length L value
8mm~10mm；Specific value can be set according to actual conditions.
The utility model embodiment also provides a kind of lens, including the above-mentioned anti-iridescence structure of lens.When white part 3
The material of backgauge portion 12 is melted and is brought into red part 1, together during the junction by black part 2 and red part 1 is flowed by melt
When the material of black part 2 is melted and the material of black part 2 is driven to fill up the part that backgauge portion 12 flows away, to prevent the material of black part 2 from flowing
Enter into red part 1, solve the problems, such as lens iridescence, improves the quality of production of lens.
Embodiment of above only elaborates the basic principles and features of the present invention, and the utility model is not by above-mentioned reality
The mode of applying limits, and on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes,
These changes and changes fall within the scope of the claimed invention.The utility model requires protection scope is by appended
Claims and its equivalent thereof.
