[technical field]
The present invention relates to a kind of mould of able to regulate concentricity, particularly a kind of mould that improves its manufacturing optical mirror slip concentricity.
[background technology]
When using mould to make profiled member, the working accuracy of profiled member (as concentricity etc.) mainly is subjected to the influence of mould manufacturing and assembly precision, therefore, the manufacturing of raising mould and assembly precision can make the profiled member (product) of using this mould manufacturing possess higher precision.In the existing mold manufacturing processed, the control accuracy mode generally includes: first kind of mode will be for will need the surface of control accuracy to be located at disposable processing on same die cavity or the core, make the die cavity or the core of manufacturing have higher precision, and then guarantee to have higher precision at the profiled member that uses this die cavity or core production; The second way is for to be provided with some bolts at part periphery to be processed, and part produces displacement to realize regulating precision such as concentricity during bolt by different rotation angle; The third mode is by being put down in writing mould structure as the novel patent specification of TaiWan, China (notification number 261050), between its template, the slide block certain interval is set at core and interspersed this core of installation, utilize this gap when ejection formation, to adjust its precision, make plastic prod have concentricity preferably for formed materials such as plastics.
Yet all there is certain deficiency in above-mentioned three kinds of modes: when first kind of mode was difficult on same die cavity or core for the surface of need control accuracy, its application just was restricted; The second way is more suitable for using when carrying out the machining of rotating shaft, when its when around the core some adjusting bolts being installed, can influence the installation of other structure (as guide pillar) on the template, simultaneously, bolt props up core after need passing template, this just causes bolt long, and the sharpness of regulation of bolt own just is affected; Existing gap makes the big part of core quality by unsettled in the mould of the third mode, cause all-mass only to rely on the less axle of diameter of core to support, cause the heavier part flexural deformation of core (step shaft), so the axle center of the each several part of the step shaft of core is on same medullary ray, and then is difficult to reach the effect that improves the plastic prod concentricity that causes.
In view of above-mentioned deficiency, be necessary in fact to provide a kind of accurately and reliably, the mould of adjustment concentricity simple in structure.

[embodiment]
See also Fig. 1 and Fig. 3, mould 100 of the present invention comprises solid plate 1, moving platen 2, core 3 and governor lever 4.Be formed with die cavity 10 on the solid plate 1, die cavity 10 has a sphere 12, and sphere 12 injects the side surface that the back forms optical mirror slip for shaped material (as glass, plastics etc.).Moving platen 2 and solid plate 1 are relative and establish.Be formed with a step-like through hole 20 on the moving platen 2, this through hole 20 runs through end face 22, forms a circular hole 24 on the end face 22 thereby make, on the circumference of circular hole 24, be marked with equally spaced scale, graduated dense degree depends on the accuracy requirement of adjusting, and scale is intensive more, and the precision of adjusting is high more.Core 3 is a step shaft, the outer face 30 of the small diameter shaft of this step shaft is formed with projection 34, projection 34 has sphere 36, sphere 36 injects the opposite side surface that the back forms optical mirror slip for shaped material, the centre portions of the outer face 32 of major diameter axle offers a junction 38 (as trilateral, Polygons or bulge loop etc.), also is carved with a pointer 39 on the circumference of outer face 32.Governor lever 4 can be L shaped or Z-shaped or other structure, and its end 40 is connected by connection section 38 separably with core 3.Mould 100 also possesses due other structure of existing ejection shaping die such as runner, cast gate, guide pillar, guide pin bushing or the like, does not repeat them here.
See also Fig. 2, during assembling, core 3 is embedded in the through hole 20 of moving platens 2, and make the outer face 32 of major diameter axle of core 3 concordant, then with solid plate 1 and moving platen 2 matched moulds with the end face 22 of moving platen 2.
Please consult Fig. 3 simultaneously, during die trial, at first injection moulding material in die cavity 10 obtains profiled member 5 after the moulding, after profiled member 5 is taken out, delivers to the concentricity that optical detector detects its two sphere 50,52.Because the both sides sphere 50,52 of profiled member 5 fits like a glove with the sphere 12 of die cavity 10 and the sphere 36 of core 3, thereby the concentricity between the sphere 36 of the sphere 12 of the concentricity of the profiled member 5 that obtains of detection and die cavity 10 and core 3 is consistent.Note the scale of pointer 39 indications of this moment,, then do not need to adjust again core 3 if concentricity meets accuracy requirement.Otherwise, use governor lever 4 rotating core 3 certain angles once more, this moment once more behind the matched moulds to obtain new profiled member 5, after detecting through optical detector,, then do not need to adjust again core 3 if concentricity meets accuracy requirement.Otherwise, need repeat above-mentioned action, repeatedly regulate till meeting the demands through the detected concentricity of optical detector, after this, keep this position to make after the profiled member of volume production all satisfy the requirement of concentricity.
