7b is necessarily in the downstream position of quadratic form cold runner 9.When carrying out quadratic form injection molding, that is, being molded black part, black part melts
Glue will not enter in dispensable mould cold runner 1 or dispensable mould cold runner 22, be not necessarily to redesign the hole slot of anti-interference on cover half 14,
Die cost is saved.
The length direction of above-mentioned quadratic form slag well cavity 10 is adapted with the length direction of quadratic form cold runner 9.
It is illustrated below with reference to Fig. 4,5 pairs of injection moulding process.
In conjunction with shown in Fig. 4,8, in mold-closing injection, i.e. the die joint of dynamic model 6 and the die joint of cover half 14 is fitted closely, and is made
It obtains dynamic model 1 and is directed at cover half 1, the alignment cover half 2 13 of dynamic model 25, so that 7 face dispensable mould cold flow of dispensable mould injection channel
The melten gel of Transparent Parts is first passed through dispensable mould injection channel 7 against dispensable mould cold runner 22 by road 1, quadratic form slag well cavity 10
It is injected into dispensable mould cold runner 1, the melten gel of Transparent Parts passes sequentially through dispensable mould injection channel 7, dispensable mould cold runner one 1, one
Secondary type side gate 3 separately flows into two type chambers, forms Transparent Parts after condensation to be hardened, to complete to be molded for the first time.
In conjunction with shown in Fig. 5,6,7,8, dynamic model 6 is rotated into 180 degree, so that dynamic model 1 is directed at cover half 2 13,25 pairs of dynamic model
Certainly mould 1, so that 7 face dispensable mould cold runner 22 of dispensable mould injection channel, quadratic form slag well cavity 10 against one
Secondary type cold runner 1, the melten gel of black part pass sequentially through quadratic form injection channel 8, quadratic form cold runner 9, quadratic form side gate 11 and divide
Black part Liu Ru not be formed after condensation to be hardened and is combined with Transparent Parts, since dispensable mould cold runner 1 is full of in two type chambers
The Transparent Parts that hardening is completed can stop the black part melten gel of quadratic form cold runner 9 to invade dispensable mould cold runner 1.It walks herein
In rapid, the melten gel of Transparent Parts can be injected in dispensable mould cold runner 22 by dispensable mould injection channel 7 simultaneously.Black part is waited to harden
After the completion, a secondary double-colored lens product has been molded completion, finally will entire double-colored lens product top with mandril and jacking block
Out.
Above-mentioned two step is repeated, and every injection molding is primary just to rotate 180 degree for dynamic model 6, to complete to be molded.
In 10 region of quadratic form slag well cavity, the black part front end melten gel of quadratic form hardly enters back into after flowing into, i.e.,
Making, which has a small amount of dispensable mould Transparent Parts to be hacked part stream, melts and is mixed into black part stream, can not also distinguish in visual effect,
It will not influence the injection molding effect of black part.
It is the preferred embodiment of the utility model above, those of ordinary skill in the art can also carry out respectively on this basis
Kind of transformation improves, and under the premise of not departing from the utility model total design, these transformation or improves this reality all should belong to
Within the scope of novel be claimed.
