A into glue runner, all entrances into glue runner are connected to melt adhesive runner, and all outlets into glue runner are to connect with die cavity
Logical cast gate, and cast gate and die cavity be in being arranged in a one-to-one correspondence, driving device valve needle plate, to drive all needles into glue
It is moved synchronously in runner to open or seal cast gate.
Wherein, the spacing between two neighboring cast gate is 2.9~4.5mm.
Wherein, the spacing between two neighboring cast gate is 2.9mm.
Wherein, the bore of each cast gate is 0.30~0.34mm.
Wherein, the bore of each cast gate is 0.32mm.
It wherein, into the maximum gauge of glue runner is each 1.95~2.05mm.
Wherein, each into the length of glue runner be 20mm.
Wherein, each into the outlet end of glue runner be back taper setting.
Wherein, the second circular cone for including each the first circular conical surface into the outlet end of glue runner and being connect with the first circular conical surface
Face, the cone angle of the first circular conical surface are 60 degree, and the cone angle of the second circular conical surface is 40 degree, and the osculum end of the second circular conical surface is cast gate.
Wherein, runner plate is equipped with is arranged in sliding through hole with the one-to-one sliding through hole of needle, needle sliding.
Beneficial effects of the present invention:
More needles are fixed in valve pin plate, driven by intensive valve needle type hot flow passage system of the invention by the way that valve pin plate is arranged
Dynamic device is moved by valve needle plate, and then all needles is driven to move synchronously, and which guarantee the one of all valve needle movements
Cause property, and since to do the spacing between adjacent needle smaller for the reduction of driving device, then by into offset plate
It is equipped with needle correspondingly into glue runner, and all entrances into glue runner are connected to melt adhesive runner, it is all into glue
The outlet of runner is the cast gate being connected to die cavity, and cast gate and die cavity correspond, in this way due to eliminating in the prior art
Hot mouth that the spacing between adjacent gate is accomplished is smaller, the present invention is by the distance between adjacent needle and adjacent gate
It can be made small, can really realize the production of small spacing, densely arranged product.

Specific embodiment
The invention will be further described with the following Examples, intensive valve needle type hot flow passage system of the invention, such as Fig. 2
With shown in Fig. 3, for structure from left to right successively including driving device 10, runner plate 20 and into offset plate 40, driving device 10 is gas
Cylinder or oil cylinder, the piston plate 100 of driving device 10 are connected with valve pin plate 30, and more needles 60 are connected on valve pin plate 30, stream
Guidance tape 20 is equipped with the melt adhesive runner flowed for melten gel, is equipped with into offset plate 40 with needle 60 correspondingly into glue runner 50, each
Left port into glue runner 50 is connected to melt adhesive runner, is each cast gate 500 into the right output port of glue runner 50, with cast gate
500 pair mode be a multi-cavity mold, a die cavity 90 of the corresponding mode of cast gate 500, and corresponding cast gate 500 and mould
Chamber 90 is connected to, the movement of 10 valve needle plate 30 of driving device, and then drives all needles 60 into moving synchronously in glue runner 50
To open and seal cast gate 500.
Since valve pin plate 30 is able to drive, all needles 60 move synchronously the present invention, and which guarantee the movements of all needles 60
High consistency and synchronism, and then the individual difference of same batch products can be effectively reduced, and due to driving device 10
It reduces that the spacing between adjacent needle 60 is done is smaller, and the structure of hot runner system with valve needle is done more
Simply, equipment cost is thereby reduced.
The present invention directly sets the right output port into glue runner 50 for cast gate 500, eliminates hot mouth in the prior art, this
Spacing between two neighboring cast gate 500 is accomplished smaller, the present invention will be between adjacent needle 60 and adjacent gate 500
Distance can accomplish very little, the production of small spacing, densely arranged product could be made to be achieved, in addition eliminate hot mouth
Structure also further simplifies the structure of hot runner system with valve needle.
In the present embodiment, the spacing between two neighboring cast gate 500 can accomplish 2.9~4.5mm, and each cast gate 500
Bore can accomplish 0.30~0.34mm.The present embodiment is applied into the production in LED lamp holder, two neighboring cast gate 500 it
Between minimum spacing be 2.9mm, maximum spacing be 4.5mm, and the bore of each cast gate 500 be 0.32mm.
In the present embodiment, melten gel is more uniform, successfully flows into glue runner 50 to make, each into the length of glue runner 50
It is each 2mm into the maximum gauge of glue runner 50, the diameter of needle 60 is 1mm for 20mm.
As shown in figure 3, being each back taper setting into the outlet end of glue runner 50, the outlet end of back taper is by the first circle
The conical surface 70 and the second circular conical surface 80 connecting with the first circular conical surface 70 composition, the cone angle of the first circular conical surface 70 are 60 degree, the first circle
The big opening end of the conical surface 70 has rounded corner with the inner wall into glue runner 50, and the cone angle of the second circular conical surface 80 is 40 degree, the second circular conical surface
80 osculum end is cast gate 500.When needle 60 moves downward, cast gate 500 is opened, melten gel is through the first circular conical surface 70 and the second circular cone
Face 80 uniformly and quickly flow to cast gate 500, so that the melten gel at cast gate 500 also uniformly and quickly fills die cavity 90, thus
Obtain the preferable product of quality.When needle 60 moves right, the taper top end face of needle 60 is supported in the big of the second circular conical surface 80
Mouth end, and then cast gate 500 is sealed.
As shown in Fig. 2, runner plate 20, which is equipped with, is arranged in sliding with the one-to-one sliding through hole of needle 60, the sliding of needle 60
In through-hole.Sliding through hole plays position-limiting action to the needle 60 of side-to-side movement, can effectively prevent the deformation of needle 60 and fracture.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
