There is groove 18 by 1604 end of the second end of injecting products in this present embodiment, so in male model 4 also
It is provided with the second mold insert 702 for being used to prepare groove 18, as shown in fig. 6-7.When being molded, the second mold insert 702
Top is located in male model glue position 401.Elastic component is provided between male model 4 and male model pressing plate 5, the effect of elastic component is in male model 4
Male model 4 and male model pressing plate 5 are flicked when separating with male model pressing plate 5；When male model 4 is bonded with male model pressing plate 5, promote the second mold insert
It is moved on 702 in male model glue position 401.Fall the second mold insert 702 after rise, the second mold insert
702 separate with male model glue position 401 or product, facilitate taking-up injecting products.Elastic component is preferably spring.
In the present embodiment described briefly below can post forming mold the course of work:
Carry out for the first time injection molding project before, at this time master mold pressing plate 2 be close to master mold 3, male model pressing plate 5 be close to male model 4, first
Movable plate 1401 and the second movable plate 1402 are close to male model glue position 401, the first master mold glue position 301 of master mold 3 and male model glue position 401
Corresponding to form the first cavity for accommodating first time injecting products 1601, filling bar 13 is located in the first cavity, the second mold insert 702
Top be located at the second end 1604 of the first cavity, as shown in fig. 6-7.
And then first time injection molding is carried out, the high molecular material or metal material of flowing are injected in the first cavity, through cold
But first time injecting products 1601 are formed afterwards.
After the completion of being molded for the first time, master mold 3 is moved up, and male model 4 and master mold 3 are separated from each other.Master mold 3 moves up can band
Dynamic first pull rod 1901 moves up, when the sliding block 21 of the second pull rod 1902 slides into the bottom of the first pull rod 1901, the first pull rod 1901
The second pull rod 1902 is pulled up, and then the second liftout plate 2202 is driven to move up, pushes the first thimble 2301 and the first liftout plate
2201 move up, to runner 17 be ejected, as shown in figs. 23-24.First movement plate 1401 on male model 4 and the second movement at this time
Plate 1402 is motionless, and filling bar 13 stays in first time injecting products 1601, and third liftout plate 2203 and the 4th liftout plate 2204 are not
Dynamic, the second thimble 2302 does not make ejection movement, stays in first time injecting products 1601 motionless in male model glue position 401.
Then 4.0mm is flicked between master mold pressing plate 2 and master mold 3, first driving device 1501 is mobile with carry-over bar 10, passes through
Gear 9 rotates and then the first mold insert 701 is driven to be rotated, and after accurately rotating 180 ° by limiting device, master mold pressing plate 2
Again it is affixed on master mold 3, male model 4 is molded with master mold 3, the position phase of the first master mold glue position 301 and the second master mold glue position 302
It mutually exchanges, the second chamber for forming second of injecting products 1602 of receiving corresponding with male model glue position 401 of the second master mold glue position 302
Body.
Then it carries out being molded for second, the high molecular material or metal material of flowing is injected in the second cavity, through cooling
After form second of injecting products 1602.Second of injecting products 1602 is shape on the basis of first time injecting products 1601
At.Do not change close to the part of male model glue position 401, only in the side close to master mold 3 due to by the first master mold glue position 301
The second master mold glue position 302 is replaced with, so that final injecting products generate variation.
As shown by figures 25-26, after the completion of second of injection molding, master mold 3 is moved up, and male model 4 and master mold 3 are separated from each other.It is public
The first movement plate 1401 on 4 both sides of mould and the second movable plate 1402 are respectively by the second driving device 1502 and third driving device
1503 band trend two sides skid off, and wherein first movement plate 1401 drives filling bar 13 to be detached from second of injecting products 1602.Meanwhile
It is separated from each other 8.0mm between male model pressing plate 5 and male model 4, so that elastic component is fallen after rise, the second mold insert 702 and second of injecting products
1602 are separated from each other to facilitate taking-up product.
As shown in figure 25, master mold 3, which moves up, will drive the first pull rod 1901 and moves up, and the sliding block 21 of the second pull rod 1902 is sliding
When to the bottom of the first pull rod 1901, the first pull rod 1901 pulls up the second pull rod 1902, and then drives the second liftout plate
2202 move up, and push the first thimble 2301 and the first liftout plate 2201 to move up, so that runner 17 be ejected.In the first thimble 2301
While moving upwards, the 4th liftout plate 2204 can also be moved up, to push the second thimble 2302 and third liftout plate
2203 move up, so that second of injecting products 1602 be ejected.I.e. by the first thimble 2301 and the second thimble 2302, most
Eject runner 17 and second of injecting products 1602 simultaneously eventually.Then second of injecting products 1602 is removed from the molds.
At this point, injecting products complete, a circulation terminates.Then master mold pressing plate 2 and master mold 3 are separated from each other 4.0mm,
The first mold insert 701 in master mold 3 is overturn by the driving of rotating mechanism, and accurately rotates 180 ° by limiting device
Afterwards, master mold pressing plate 2 falls, and male model 4 molded with master mold 3, formed between male model 4 and master mold 3 after first cavity carry out it is next
The first time of a circulation is molded.
Male model 4 in the present embodiment only has a kind of male model glue position 401, in other examples, can also set in male model 4
The form being set to as the first mold insert 701 being similar in master mold 3, to prepare various forms of products.
