Core and lower mold core collectively constitute die cavity, be provided with sprue bush, be provided with main flow in described sprue bush in described cope match-plate pattern and middle template
Road, described sprue one end connects with die cavity, and the other end connects with the material mouth shower nozzle located at upper runner top of the plate portion, described lower flow channel
Some cooling water pipes are distributed with plate, if dry heat pipe is distributed with described thermal insulation board.
Preferably, described upper mold core and lower mold core correspondence position are respectively equipped with alignment pin and lower alignment pin.
Preferably, described middle template and cope match-plate pattern correspondence position are respectively equipped with positioning guide column and positioning guide pin bushing.
Preferably, described upstream guidance tape is provided with locating ring.
Compared with prior art, the beneficial effects of the utility model are: a kind of cold-runner rubber described in the utility model
Injection multi-cavity mold, using preferred design, structure compact to design, comprehensively take into account the wave reducing rubber burrs
Take, its novel flow channel system structure design and thermal insulation board are designed to effectively control the temperature of rubber in runner so as to not reach
While to curing temperature, there is good mobility, can recycling in the injection of next mould product all the time, thus playing not
Waste the effect of runner overlap.

Specific embodiment
Effect for making to architectural feature of the present utility model and reached has a better understanding and awareness, in order to relatively
Good embodiment and accompanying drawing cooperation detailed description, are described as follows:
A kind of cold-runner rubber injects multi-cavity mold, include successively from top to bottom lower template 1, middle template 2, cope match-plate pattern 3, every
Hot plate 4, dirty guidance tape 5 and upper guidance tape 6, described lower template 1 is provided with lower mold core 7, and described cope match-plate pattern 3 is provided with upper mold core 8,
Described upper mold core 8 and lower mold core 7 collectively constitute die cavity 9, are provided with sprue bush 10 in described cope match-plate pattern 3 and middle template 2, described pour
It is provided with sprue 11, described sprue 11 one end connects with die cavity 9, the other end and located at upper guidance tape 6 top in muzzle 10
Material mouth shower nozzle 12 connects, and some cooling water pipes 13 is distributed with, if being distributed with xeothermic on described thermal insulation board 4 on described dirty guidance tape 5
Pipe 14, described upper mold core 8 and lower mold core 7 correspondence position are respectively equipped with alignment pin 15 and lower alignment pin 16, described middle template 2 He
Cope match-plate pattern 3 correspondence position is respectively equipped with positioning guide column 17 and positioning guide pin bushing 18, and described upstream guidance tape 6 is provided with locating ring 19.
Described upstream guidance tape 6 and dirty guidance tape 5 connect the runner locking together formation rubber flowing by conventional stud, by
In rubber injection and sulfuration all there is larger pressure, so before two runner plates mating part reached using interference fit close
The effect of envelope rubber, will not overflow the effect of mould when so that rubber is passed through.
The temperature of described cope match-plate pattern 3 and upper mold core 8 needs to reach rubber sulfurizing temp, so this utility model is in cope match-plate pattern
It is provided with heat pipe 14 5 in 3 it is carried out heating the effect reaching rubber sulfurizing temp.
Described cooling water pipe 13 can circulate cooling liquid sprue bush 10, thermal insulation board 4 and above part are carried out cold
But with reach rubber can runner, but the temperature of not sulfidization molding, so the rubber inside runner is not in traditional all the time
Sulfidization molding, so the runner of every mould would not waste because of sulfidization molding.
The rubber of described dirty guidance tape 5 is flowed directly in die cavity by the sprue bush 10 of medium design and is vulcanized, rubber
Temperature during this all below curing temperature, sprue bush 10 and dirty guidance tape 5 radial interference fit, sprue bush 10 and every
The gap cooperation of hot plate 4, interference fit between sprue bush 10 and cope match-plate pattern 3, the gap cooperation of sprue bush 10 and upper mold core 8, pour
The axial direction of muzzle 10 has 20 magnitudes of interference respectively at dirty guidance tape 5 and upper mold core 8, has reached the effect of caulking gum.
Can be by changing upper mold core 8 and the lower mold core 7 of different product, a secondary multiple product of mould can be produced,
Reach the effect of interchangeability.
Flow passage system is the cold runner system being made up of thermal insulation board 4, dirty guidance tape 5, upper guidance tape 6 by traditional structural transformation
System, can effectively reduce the waste of rubber burrs.
Operation principle of the present utility model: make rubber temperature inside its flow passage system all the time sulfidization molding temperature with
Under, rubber can also possess good mobility simultaneously, and mold cavity temperature can reach the normal curing temperature of rubber, so
Would not situation about wasting in rubber inside runner, but can be used in the injection fillers of next mould all the time, and this effect is just
It is the place of critical significance of the present utility model.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Plant changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requires
Protection domain defined by appending claims and its equivalent.
