Technical field
The present invention relates to injection molding field, particularly relates to a kind of integrated multiple spot hot flow path of core and quickly fill out
Fill structure.
Background technology
Plastic injection mould all has sprue, runner, this is to obtain plastic part and the part that must be provided with.
The running gate system being made of sprue, runner can consume injection pressure in injection moulding, make the pressure reduction in cavity.
And gating system of material occupies significant proportion in the molding melt of a shot, and when these condensates are recycled, performance
Decline, the plastic of high-quality cannot be produced, cause very big waste, in order to overcome the problems, such as this, then people create hot flow path
Technology.Hot flow path running gate system and common running gate system difference lies in：Plastics in entire production process in running gate system
Always it is in molten condition.The structure of hot-runner injection mould has at present：(1) well formula nozzle, it is in nozzle of injector and mould
There are one sprue cups for dress between having entrance, and cup is adiabatic using air-gap outside, the storing well for having section larger in cup, and volume is about
The 1/3~1/2 of plastic volume；(2) cavity heat-insulating hot channel, it is that the beginning of cast gate is charged into runner, makes part down gate
Under heat preservation in runner heat insulation layer.The bushing surrounding of drop gate is additionally arranged heating collar, is heated as auxiliary, to prevent
Cast gate condenses.It is adiabatic that air gap is equipped between gate bush and solid plate.Although the above hot runner injection mould they dynamic securely may be used
It leans on, pressure transmission is good, and mould structure is simple, manufactures, is easy to maintenance, but the unbalanced stress after product injection molding easily causes change
Shape phenomenon, and the problem of thin-gage goods difficult forming.
Invention content
To solve the problems mentioned above in the background art, it is integrated more that the purpose of the present invention is to provide a kind of cores
Point hot flow path Fast Filling structure.
To achieve the above object, the technical solution that the present invention takes is：
A kind of integrated multiple spot hot flow path Fast Filling structure of core, including hot runner manifold, core and core seat board, institute
Hot runner manifold and core is stated to set up separately at core seat board both ends, if the hot runner manifold include the first guidance tape, the second guidance tape and
Dry third guidance tape, several third guidance tapes are laid at equal intervals on the periphery of first guidance tape, in first guidance tape
Middle part offers hot-fluid through-hole, and flow divider valve core and flow divider, the flow divider are embedded with respectively at the both ends of the hot-fluid through-hole
Core is located at first guidance tape close to the side of the core seat board, and the flow divider is located at first of backboard from the type
The side of core print seat plate is also associated with second guidance tape in first guidance tape side equipped with the flow divider, described
One guidance tape and each the third guidance tape are towards the core side also at least provided with a nozzle.
In above-mentioned technical proposal, it is equipped with a first flow in first guidance tape, is equipped in second guidance tape
One second flow channel, is equipped with a third flow channel in each third guidance tape, the first flow, second flow channel and every
Third flow channel is connected to the hot-fluid through-hole；
Each nozzle on first guidance tape is arranged to be connected to the first flow, is arranged in each third
Each nozzle on guidance tape is connected to the third flow channel being equipped in corresponding third guidance tape.
In above-mentioned technical proposal, each nozzle one end being arranged on first guidance tape is connected to first guidance tape, separately
One end both passes through on the core seat board and stretches to the core.
In above-mentioned technical proposal, the quantity of the third guidance tape is 2~6.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the multiple spot nozzle of hot flow path is conducive to Fast Filling into glue, reduces and flows long ratio, not only solves large size, thin walled system
The phenomenon that product difficult forming, further improves the unbalanced stress after product injection molding and causes metaboly.
2, the present invention uses hot flow path and core integral structure, compact reliable, saves space.Hot flow path is together with core
Movement need not increase additional driving element, simple in structure reliable, while also reduce the working service cost in later stage.
