Preceding mould 12 is set to preceding mould bases 11；Preceding mould 12 is equipped with die cavity 121.Afterwards mold mechanism 2 include lower code mask 20, rear mould bases 21 and after
Mould 22, rear mould bases 21 are fixed in lower code mask 20, and rear mold 22 is set to rear mould bases 21；Rear mold 22 is equipped with and 121 matched mould of die cavity
Core 221.Preceding mould 12 is oppositely arranged with rear mold 22, and preceding mould 12 is corresponding with rear mold 22, and die cavity 121 is matched with mold core 221；Mould
The size and shape of chamber 121 and the size of injecting products 8 and formed consistent, when mold-closing injection, injecting products 8 are specifically in die cavity
It is shaped between 121 and mold core 221.
Running gate system 40 includes hot runner flow distribution plate 401, main hot flow path 402, divides hot flow path 403 and hot mouth 404,
In, it is multiple to divide the quantity of hot flow path 403 and hot mouth 404.Hot runner flow distribution plate 401 is set to lower code mask 20 and rear mold
Between frame 21；One end of main hot flow path 402 is set to lower code mask 20, and the other end sequentially passes through hot runner flow distribution plate 401, mould bases
21 and rear mold 22 after connect with the rear end of a hot mouth 404, the rear end of hot mouth 404 is specially one end of melt plastic cement injection；It is main
Hot flow path 402 is connected to hot runner flow distribution plate 401；One end of each point of hot flow path 403 is communicated in hot runner flow distribution plate 401,
The other end is connect after sequentially passing through rear mould bases 21 and rear mold 22 with the rear end of a hot mouth 404；The front end of multiple hot mouths 404 is all provided with
In die cavity 121, the front end of hot mouth 404 is specially one end that melt plastic cement sprays.The particular number of point hot flow path 403 can be according to waiting for
The shape of injecting products 8 is configured, for example, dividing hot flow path 403 number needed for being confirmed according to the size of injecting products 8；
The quantity of hot mouth 404 is specially to divide the quantity of hot flow path 403 and the sum of the quantity of main hot flow path 402.
When injection molding, the melt plastic cement that injection molding machine projects is located at the end entrance of lower code mask 20 from main hot flow path 402, then
Melt plastic cement is shunted to each point of hot flow path 403 by hot runner flow distribution plate 401, and last melt plastic cement enters multiple hot mouths
404, then melt plastic cement is injected into die cavity 121 respectively by multiple hot mouths 404, then melt plastic cement is cooled into corresponding note
Molding product 8.The pan feeding of melt plastic cement is may make by being injected while multiple hot mouths 404 evenly, and hot flow path point is rationally set
Flowing plate 401, main hot flow path 402, the position for dividing hot flow path 403 and hot mouth 404 may make that melt plastic cement is uniform in die cavity 121, obtains
Obtain homogeneous high-quality injecting products 8；For example, the position distribution setting of multiple hot mouths 404 and the sizes of injecting products 8 and
Shape is related, and the hot mouth 404 being connect with main hot flow path 402 should be located at the center of die cavity 121, remaining connect with hot flow path 403 is divided
Hot mouth 404 surround die cavity 121 the evenly dispersed arrangement in center, do not interfere with each other each other, but ensure integral molded plastic balance.
Thimble demoulding mechanism 50 includes ejector retainner plate 501, ejection thimble part 502 and actuator 503；Ejector retainner plate 501 is set to
Hot runner flow distribution plate 401 is close to the side of rear mould bases 21；The one end for ejecting thimble part 502 is set to ejector retainner plate 501, the other end according to
It is secondary to run through rear mould bases 21 and rear mold 22；Ejection thimble part 502 respectively with main hot flow path 402 and divide hot flow path 403 parallel；It drives
The output end of moving part 503 is connect with ejector retainner plate 501；The quantity of ejection thimble part 502 in the present embodiment is multiple, multiple ejections
Thimble part 502 is mutually parallel, and when demoulding, actuator 503 drives ejector retainner plate 501 to move, and drives multiple ejection thimble parts 502 simultaneously
Eject the injecting products 8 of injection formed so that uniform force when injecting products 8 demould can disposably complete stripping action.
In traditional hot runner plastic injection mould, ejector retainner plate 501 is located at one of hot runner flow distribution plate 401 far from die cavity 121
The ejections action of side, multiple ejection thimble parts 502 needs to move longer distance, and occupies larger space to complete,
Opposite, running gate system 40 will coordinate multiple ejection thimble parts 502 and self space is arranged, and ejection thimble part 502 is i.e. to pouring
Injection system 40 forms interference, and the setting of running gate system 40 has to consider 50 installation position of thimble demoulding mechanism, often
Influence the balance setting of itself.And the flip injection mold in the present embodiment is by being arranged ejector retainner plate 501 positioned at hot flow path point
Flowing plate 401 is close to the side of die cavity 121, i.e., preposition ejector retainner plate 501,401 postposition of hot runner flow distribution plate, in this way, avoiding top
Going out thimble part 502 and having to be arranged longer distance could complete ejection action, reduce the movement sky for ejecting thimble part 502
Between, and then avoid to form running gate system 40 and interfere.In addition, multiple ejection thimble parts 502 respectively with main hot flow path 402 and
Multiple points of hot flow paths 403 it is arranged in parallel, further avoid ejection thimble part 502 and main hot flow path 402 and point heat
Runner 403 causes the possibility of interference, and then influences the setting of 40 whole machine balancing of running gate system.Meanwhile the upside-down mounting note in the present embodiment
The running gate system 40 and thimble demoulding mechanism 50 of mould are respectively positioned on rear mold mechanism 2, that is to say the dynamic model part of mold, injection molding
With ejection point at rear mold 22, injecting products 8, without cast gate, ejection mark, ensure that the cast gate of mold 8 in the part of preceding mould 12
The beauty of 8 appearance of injecting products；For example, if injecting products 8 are colour TV rear shell, shape is approximately arc panel, has inside
Face and appearance, after moulding, the running gate system 40 of mold mechanism 2 and thimble demoulding after the medial surface face of colour TV rear shell
In medial surface, appearance then without cast gate, ejection mark, ensure that colour TV rear shell appearance for mechanism 50, cast gate and ejection point
The beauty in face.
Multiple reference Fig. 3, further, preceding mould bases 11 offers first groove 111 compatible with preceding mould 12, and preceding mould 12 assembles
In in the first groove 111；Mould bases 21 offers second groove 211 compatible with rear mold 22 afterwards, and it is recessed that rear mold 22 is assemblied in second
In slot 211；The assembly of preceding mould 12 and rear mold 22 is convenient in the setting of first groove 111 and the second groove 211.Specifically, upper code
Template 10, preceding mould bases 11 and preceding mould 12 can be fixed by hex screw, and lower code mask 20, rear mould bases 21 and rear mold 22 can lead to
Hex screw is crossed to fix.
Multiple reference Fig. 3, further, the outside of lower code mask 20 is equipped with locating ring 201, and the end of main hot flow path 402 is set
In locating ring 201, locating ring 201 matches with injection molding machine injection mouth；When injection molding, the injection molding mouth of injection molding machine is set to locating ring 201,
The melt plastic cement that injector projects enters main hot flow path 402 under the positioning of locating ring 201.
Again referring to Fig.1-3, further, running gate system 40 further includes hot-fluid pavement slab 405, loading plate 406, the first cushion block
407, the first hornblock 409 and the first pillar 410, wherein the quantity of the first cushion block 407 is two, the quantity of the first hornblock 409
It it is four, the quantity of the first pillar 410 is multiple；Hot-fluid pavement slab 405 is located at hot runner flow distribution plate 401 and ejector retainner plate 501
Between；Loading plate 406 is between hot-fluid pavement slab 405 and ejector retainner plate 501；Two the first cushion blocks 407 are divided into hot flow path
