One screw hole 412, the master mold enter the master mold that son 41 is worn positioned at the caster 15 enter in sub-aperture 151 and its protrusion 413 be located at should
Locating slot 152, the fine tuning gasket 42 are arranged on the master mold and enter son 41 and in the locating slot 152, which runs through
The screw hole 412 that the fine tuning gasket 42 and the master mold enter son 41 be combined with each other fixation.
Cooperation referring to shown in Fig. 9 and Figure 10, due to the male die insert hole 141 and the master mold enter sub-aperture 151 process simultaneously and
Processing is ground to its hole wall simultaneously so that the center line that the male die insert hole 141 and the master mold enter sub-aperture 151 is accurate
At same center, furthermore the male model bushing 32 and male die insert 31 are moved on the basis of the male die insert hole 141, and are somebody's turn to do
Master mold enter son 41 by the master mold enter sub-aperture 151 on the basis of move, according to same basis displacement, therefore with preferably essence with one heart
Degree.
The die cavity for making molded lenses is made of this with 411 and first depression 311 of female die cavity with the second depression 321, if being intended to
During the lens dimension difference of making, then the male model bushing 32 of replaceable another size, i.e. the second depression with another size
321, the male die cavity of another size will can be organized in the bush hole 322 worn with former male die insert 31 positioned at the male model bushing 32,
There is the die cavity of another size to form one in cooperation master mold 411, and can be made into the eyeglass of another size, when outside the eyeglass of making
Footpath only needs to change male model bushing 32 when changing, and without entire template is replaced, can save cost of manufacture.
Furthermore it mutually reclines in the male template 14 and the caster 15 and completes mold closing, at this time by first depression 311 and the
There is a die cavity, the other end of the die cavity and the runner 153 connects between the male die cavity and the female die cavity 411 that two depressions are formed
Connect, to make the plastics of optical mirror slip by the flow channel component 16 sprue 161 through the runner 153 into the male die cavity with
In the female die cavity 411, as shown in figure 11, after eyeglass is molded in die cavity, the caster 15 and its master mold enter son 41 and the male model
Plate 14 and its male die insert 31 and male model bushing 32 are separated from each other, when the knock-pin 110 passage positioned at the board 13 this
Two liftout plates 134 and first liftout plate 133, sequentially elapse the fine tuning gasket 34 and the public affairs via the male model knock-pin 21 at this time
Mould enters son 31, and the end that the male model bar 310 of the male die insert 31 has first depression 311 can release molded eyeglass
Male die cavity, since the male die insert 31 is comprehensive and be oriented parallel to the male die insert hole 141 with ejection, which will be to be in
Average force mode ejects, and then can ensure that eyeglass surface figure accuracy.
Cooperation is referring to shown in Figure 12, and the male die insert 31 reverse movement resets, which drives the knock-pin 110 to move
The male model knock-pin 21 will be fixed simultaneously by, which moving, is moved, and the contour screw 22 is driven to force to be repositioned to the distance of the interval S
It is interior, make the natural return of the male die insert 31 using the elastic force inertia of the spring 220 at this time, will so can ensure that and will not interfere with this
Male die insert 31 and cause to tilt, and then can avoid and abnormal friction destruction between the male die insert hole 141.
If again when the inertia return of spring 220 can not simultaneously make the male die insert 31 be accurately located at the distance of the interval S with
Interior, since each mould time is in mold closing, the high pressure formed in die cavity is all identical and stablizes, therefore can aid in so that the male model
Enter son 31 to be accurately positioned.
