Description
Technical field
The utility model relates to a kind of plastic rubber mold structure, especially a kind of precision plastic rubber lens mold structure.
Background technology
Traditional plastic lens mould structure is to add die in the lining, lining control positioning reference external diameter, die control aspheric surface face type since between processing and the error that cooperates, can not reach the requirement of production high eccentricity precision.Along with the continuous increase of mobile phone camera function, the mobile lens pixel is also slowly increasing, and the mobile lens pixel of selling has in the market reached 5,000,000 even 8,000,000 pixels, possibly have the demand of higher pixel camera lens later on.It is also increasingly high to the requirement of eyeglass in the camera lens that the camera lens pixel increases the back, and the aspheric surface off-centre of eyeglass was at 5～8 μ when former camera lens pixel was low, and the resolving power of camera lens can reach requirement basically; But along with the increase of camera lens pixel, just increasingly high to the off-centre requirement of eyeglass, off-centre need be below 2 μ, and camera lens is separated picture just can reach necessary requirement.Eccentricity of glasses lens precision 5～8 μ that present industry can guarantee, also very difficult concerning existing mould structure, 2 μ are with interior can't the realization (just contingency, formally volume production).
The utility model content
The technical problem that the utility model will solve provides a kind of mould structure that can improve the eccentric precision of aspheric surface.
Designed a kind of precision plastic rubber lens mold structure for solving the problems of the technologies described above the utility model; Include front template and rear pattern plate; Be respectively equipped with pilot hole and following pilot hole on said front template and the rear pattern plate, said going up in the pilot hole is equipped with the die lining, in the said die lining die that can adjust up and down is installed within it; Be provided with whole die in the pilot hole under said, this integral body die includes disposable positioning reference external diameter and the aspheric surface that processes.
It is identical and be disposable last pilot hole that processes and following pilot hole to be respectively equipped with internal diameter on said cope match-plate pattern and the lower bolster.
The locator that is used to locate is installed on front template and the rear pattern plate, and said locator is installed in the through hole that front template and rear pattern plate last time property process.
Be symmetrically arranged with two centre holes in the said whole die, be provided with in the said centre hole can before and after slide and eject the thimble of product.
Said whole die and die lining contact-making surface prolong upper runner and the lower flow channel that radially offers respectively with charging runner UNICOM.
The utility model is compared with the traditional moulds structure has following advantage:
1) design of the positioning reference external diameter of eyeglass and a side aspheric surface is on a die; Pass through the processing of disposable completion external diameter of superhigh precision aspherical mirror machining machine and face shape on the processing technology; Axiality between aspheric surface external diameter and the aspheric surface can guarantee in 0.5 μ, avoids aspheric surface and the design of positioning reference external diameter produce on different parts in the traditional structure processing and mismatch error;
2) adopt whole die and lining to add the structure of die; The die external diameter of front and back template is not just influenced by the shape size of eyeglass itself; Can make standard die of the same size, enough disposable the machining of super-precision machine tools while of the die pilot hole ability of front and back template guarantee below axiality 1 μ like this; Improve eccentric precision, the die pilot hole of template is because of the different mismachining tolerance that can't disposable processing causes of external diameter before and after avoiding in the traditional structure;
3) adopt the disposable technology of processing simultaneously of the through hole of going up pilot hole and installation positioner down; Mould will folding 1 time before and after in each forming period; Need rely on the locator that is installed in the through hole to play the repetition positioning action during matched moulds, adopt the disposable simultaneously mould axiality repeatable accuracy between non-spherical insert during matched moulds once more before and after processing can guarantee.
4) two centre holes of design in the whole die of back mould; Arrange that two thimble balances eject product; Both avoided the off-centre that causes because of fit clearance when die ejects in the traditional structure; What possibly cause in the time of effectively preventing again in the traditional structure to adopt single thimble to eject is release bad, the bad problem of exhaust in simultaneously can also fine solution traditional structure.

The specific embodiment
As shown in Figure 1 is the utility model mould structure sketch map, and major part has: front template 1, rear pattern plate 2, die lining 4, die 5 and whole die 6, locator 3.Its process is: owing to assemble the aperture up and down is unified size; Be fixed together front template 1 and rear pattern plate 2 usefulness guide pillar guide pin bushings, with the ultraprecise jig grinder from the disposable last pilot hole 11 of front template 1 and the following pilot hole 21 and the through hole 31 of rear pattern plate 2 of processing simultaneously of a side.Adopt this processing technology can guarantee the axiality between pilot hole 11 and the following pilot hole 21, and the axiality of through hole 31 is below 1 μ.Why pilot hole 21 and last pilot hole 11 and through hole 31 disposable while processing technologys under the employing; Be because mould will the folding mould 1 time before and after in each forming period; Need rely on 3 the repetition positioning actions of locator that are installed in the through hole 31 during matched moulds, the mould axiality repeatable accuracy between non-spherical insert during matched moulds once more before and after guaranteeing.
Whole die 6 as shown in Figure 2, the positioning reference external diameter 62 of eyeglass is that assurance axiality each other is in 0.5 μ with disposable the machining of the accurate die processing machine of superelevation with aspheric surface 63 in whole die 6.In whole die 6, be symmetrically arranged with two centre holes 61 with the axis vertically, in this centre hole 61, thimble 7 be set respectively, thimble 7 ejects product when the demoulding, and this set can prevent effectively that eyeglass from release bad phenomenon taking place, and makes to eject balance.Prolong at whole die 6 and die lining 4 contact-making surfaces and radially to be respectively equipped with lower flow channel 8a and upper runner 8b; Flow to 8b on described and descend to flow to 8a and in injection moulding process, be thought of as a complete runner; And be communicated with the runner 8 on front template 1 and rear pattern plate 2 contact-making surfaces, the additional shape that the offside of cast gate just in time is and eyeglass is irrelevant in this structure can play the effect of slag well; Can solve the bad problem of exhaust in the traditional structure again well, guarantee the quality of eyeglass.
Fig. 3 is not die lining 4 and die 5 with Fig. 4 wind, and die 5 can adjust up and down for 4 li at the die lining, so that the core that can adjust as required between the eyeglass aspheric surface is thick.
