Description
Technical field
The present invention relates to extrusion die field, more particularly in runner stream can on-line control rear co-extruding mould.
Background technology
With society, economic continuous development, the improvement of people's living standards, the heat preservation energy-saving of building doors and windows there has also been
Higher requirement, what the sealing of door and window played a crucial role is adhesive tape, and the adhesive tape in door and window must have enough tensile strengths, good
Elasticity, resistance to ag(e)ing, cross dimensions structure needs scientific and reasonable could so play more excellent work in terms of heat preservation energy-saving
With.Therefore adhesive tape just has special requirement, old-fashioned rear co-extruding mould, especially in scheduling and planning this respect in process of production
There is great limitation, if the rear too fast pawl mouth shaping of co-extrusion discharging can exceed size requirement during die trial, can be sent out when serious
Raw stifled mould phenomenon, the slow adhesive tape that discharged are not easy；The slow adhesive tape that discharged not easy-formation, do not reach size requirement, squeezed with principal mode material viscous
Patch loosely, easily falls off phenomenon.Shutdown processing will be carried out when situation above occurs, mold temperature to be heated is down to
Artificial unloading's heating plate, mould is needed to be repaired a die again during room temperature, it is often impossible to once to provide the yardstick that accurately repairs a die, be desirable
By making repeated attempts, ideal dimensions are finally reached.So repair repeatedly not only take a lot of work it is time-consuming, mould repeatability repair to mould
And a kind of injury, reduce the mold use life-span.
The content of the invention
The purpose of the present invention has been influence of the flow to adhesive tape dimensional structure in co-extruding flow channel after solving in debugging process,
Fast and accurately adjust the flow in runner, improve adhesive tape quality and debugging cycle, there is provided it is a kind of it is simple in construction, easy to operate,
Continuous and steady operation, operating cost are low, stream in the runner of die life can be effectively improved can on-line control rear co-extrusion
Mould.
In runner of the present invention stream can on-line control rear co-extruding mould, including first pour guidance tape and second and pour guidance tape,
Two, which pour guidance tape, is provided with runner, and first, which pours guidance tape, is provided with counter sink, and corresponding with counter sink second, which pours guidance tape, is provided with spiral shell
Pit, first, which pours the counter sink of guidance tape and second, pours the screwed hole of guidance tape through screw Joint；First pours guidance tape and the second running channel
Relevant position of the plate along runner is provided with the adjusting screw hole being adapted with adjusting screw.
As a further improvement on the present invention, the bottom of runner is flat that both sides are circular arc.
To prevent co-extrusion material from entering in adjusting screw hole, as a further improvement on the present invention, adjusting screw includes heavy
Head, external screw thread and screw rod.Countersunk head is provided with scale, controls to adjust the depth of screw regulation.The external screw thread of adjusting screw and regulation
The screw-internal thread fit of screw hole, realize the regulation up and down of adjusting screw.The external diameter size of screw rod according to runner it needs to be determined that, but need
Less than major diameter of external thread, to facilitate installation.The external diameter of screw rod keeps gap to coordinate with screw hole, prevents co-extrusion material from entering screw hole
It is interior.
As a preference of the present invention, the end of screw rod and the second spacing L for pouring guidance tape are 1mm.
In summary, beneficial effects of the present invention are：Can be after on-line control using stream in runner of the present invention
Co-extruding mould, simple in construction, easily operated and maintenance, it can be efficiently controlled according to field requirement on-line control in runner
Flow, improve debugging efficiency, reduce debugging cost, reduce mould repairing amount, and then effectively increase making for mould
Use the life-span.

Embodiment
With reference to embodiment, the present invention will be further described：
Embodiment 1
Such as Fig. 1 --- shown in 7, in runner of the present invention stream can on-line control rear co-extruding mould, first pours the He of guidance tape 1
Second pours guidance tape 2, and second, which pours guidance tape 2, is provided with runner 4, and first, which pours guidance tape 1, is provided with counter sink 10, corresponding with counter sink 10
Second pour guidance tape and be provided with screwed hole 9, first pour the counter sink 10 of guidance tape and second pour guidance tape screwed hole 9 it is mutually solid through screw
Connect；First, which pours guidance tape and second, pours relevant position of the guidance tape along runner 4 provided with the adjusting screw hole being adapted with adjusting screw 3
5.To prevent co-extrusion material from entering in adjusting screw hole, as a further improvement on the present invention, adjusting screw includes countersunk head 8, outer
Screw thread 6 and screw rod 7.Countersunk head 8 is provided with scale, controls to adjust the depth of screw regulation.The external screw thread of adjusting screw and regulation spiral shell
The screw-internal thread fit of nail, realize the regulation up and down of adjusting screw.The external diameter size of screw rod according to runner it needs to be determined that, but need it is small
In external screw thread path, to facilitate installation.The external diameter of screw rod keeps gap to coordinate with screw hole, prevents co-extrusion material from entering screw hole
It is interior.The end of screw rod 7 and the second spacing L for pouring guidance tape 2 are 1mm.
In summary, using stream in above-mentioned runner can on-line control rear co-extruding mould structure design, it is simple in construction,
Easily operated and maintenance, it can control the flow in runner well according to field requirement on-line control, effectively increase tune
Examination efficiency, reduce debugging cost and then reduce mould repairing amount, effectively increase the mold use life-span.
