Domain.
Background technology
In the prior art, it is existing for the thicker lens products of wall thickness (such as thickness is more than 20mm) for the making of lens
There is technology to be considered as the mode of multi-layer injection molding to shorten the molding cycle of product, so that pressurize is carried out to lens mould filling,
Material shrinkage is avoided, and then ensures the optical property of lens.
When carrying out multi-layer injection molding, because the upper and lower surface that preceding layer is molded the product completed is vacant state, therefore
Prior art is needed to be injected separately upper and lower surface, so need extraordinary injection machine, and extraordinary mould structure or manipulator are realized,
Such process costs are higher, and station is more on mould.
The content of the invention
The technical problem to be solved in the invention is：The multilayer heavy wall lens of prior art are in injection moulding process, it is necessary to right
Upper and lower surface is injected separately, and is so needed to use many molds and position switching mechanism, is caused injection moulding speed slower, efficiency compared with
Low, process costs are higher.
The present invention takes following technical scheme：
A kind of shaping localization method of multilayer heavy wall lens, comprises the following steps：
A) first floor product is molded：The end positions of the non-optical function of first floor injecting products are provided with to be molded with the first floor and produced
The location structure of product integrated through injection molding；
B) two layers of product injection：The first floor injecting products are together put into two layers of injection mold together with the location structure
In, location structure is positioned with two layers of injection mold, and the first floor injecting products are vacantly arranged on two layers of injection mold
Die cavity in, injection is filled to the die cavity；
C) location structure is cut down from the product for completing injection, cutting part is the non-optical of lens products
Functional part.
Further, the step B) in also continue to carry out successively to N layers of products injection, N >=3；Complete N-1 layers of product
On the premise of injection, the product after N-1 layers of product injection are completed is placed in the die cavity of N layers of injection mold, to N layers of mould
Die cavity be filled injection.
A kind of shaping location structure of multilayer heavy wall lens, including N layers of injection mold, N >=2；First floor injecting products are in head
Injection is completed in layer injection mold, the end positions of the non-optical function of first floor injecting products are provided with and the first floor injecting products
The location structure of integrated through injection molding；The location structure can be positioned with the injection mold of N layers and the above, product is vacantly set
Put in the die cavity of correspondence mould.
Further, the location structure includes locating rod 1a, and the locating rod 1a both sides have to be connected as a single entity with it
Locating piece 1b, the locating piece 1b insertions are fixed in the room between the dynamic model 5 of the injection mold and cover half 4.
Further, the locating rod top also has the chain-wales 1a1 raised up, the chain-wales and injection mould
Tool matches.
The beneficial effects of the present invention are：
1) upper and lower surface of the lens products of multi-layer injection molding can be molded simultaneously, improve the speed and effect of injection
Rate；
2) every Rotating fields single injection-molded of multi-layer injection molding lens, is changed without using multiple mold stations and position
Mechanism, significantly reduces mould and the cost of other hardware devices；
3) end positions of the ingenious non-optical function of being arranged on product of location structure, the optical property of product is not influenceed；
4) with product ontology single injection-molded when location structure only needs the first layer to be molded, the positioning of subsequent multi-layer injection is all
This location structure can be used, treats to cut off location structure after the completion of last layer of injection, whole process is reasonable in design, high
Effect.
