Abstract
The invention discloses a kind of combined type mouth mould, comprise a mouthful mould main body, the feed side end face of described mouth mould main body is connected with extruder head, described feed side end face is provided with link slot, be provided with through hole bottom described link slot, and described through hole internal fixtion is provided with the nib liner of coupling corresponding to the size of through hole.When nib liner of the present invention deforms, only can need to change strained nib liner, thus not need whole mouth mould to change, thus reduce production cost, avoid the waste of mouthful mould.
Description
Technical field
The present invention relates to die apparatus, be specifically related to a kind of combined type mouth mould.
Background technology
Mouth mould is the critical process equipment producing product in modified plastic industry.Its Main Function is exactly by the material forming through melting in double screw extruder.The material of melting can form strip-shaped materials after mouth mould, and strip-shaped materials enters follow-up production line auxiliary equipment again and forms plastic pellet.
At present, in the production of modified plastics product, the mouth mould that factory uses is integral type mouth mould.After very moment mould uses a period of time, the nib in mouth mould can deform, then whole mouth mould must be changed.Otherwise the mouth mould after nib distortion will have a strong impact on the presentation quality of plastic pellet, and production also can be caused to have some setbacks simultaneously.Owing to only must change whole mouth mould because of the nib distortion in mouth mould, this will improve production cost greatly.And the multiple nibs sometimes in whole mouth mould are deform for one or two, and most nib can also normally use, but whole mouth mould must be changed, therefore this will very large mouth mould waste.
Summary of the invention
The deficiency that the present invention exists to overcome above prior art, provides a kind of simple and reasonable for structure, reduces production cost, avoid the combined type mouth mould wasted.
Object of the present invention is realized by following technical scheme: this combined type mouth mould, comprise a mouthful mould main body, the feed side end face of described mouth mould main body is connected with extruder head, described feed side end face is provided with link slot, be provided with through hole bottom described link slot, and described through hole internal fixtion is provided with the nib liner of coupling corresponding to the size of through hole.
Preferred as one, described nib liner is fixedly installed in through hole by interference fit.The fixed installation mode of interference fit can facilitate the installation or removal of nib liner.
Preferred as one, described nib liner comprises columnar depanning section and trumpet-shaped feed zone, and described feed zone nib aperture is greater than the nib aperture of depanning section, and the charging end face of feed zone is provided with the first inclined plane.
Preferred as one, the depanning section external diameter size of described nib liner is 3mm ~ 8mm.
Preferred as one, the depanning end face of the exit side of described mouth mould main body, namely the exit end face of described nib liner depanning section is the second inclined plane, becomes angle to arrange with the mounting plane of the exit side of mouth mould main body.
Preferred as one, described mounting plane is divided into upside the first mounting plane, downside second mounting plane, and described first mounting plane, the second inclined plane, the second mounting plane are that cascaded surface is arranged.The setting of cascaded surface reduces the material manufacturing mouth mould when can ensure mouthful mould intensity, thus reduces production cost.
Preferred as one, the central shaft of described through hole and nib liner is vertical with the second inclined plane.The outlet of the depanning section of nib liner higher than the entrance of feed zone, thus improves the presentation quality of the strip-shaped materials that fused materials is formed by nib liner, also just ensure that the quality of plastic pellet.
Preferred as one, the size of described angle is 30 ° ~ 75 °.
Preferred as one, be provided with conical socket in the middle of bottom described link slot, described through hole is communicated with conical socket.Conical socket prevent melting material overflow nib liner time from link slot flow export mould, avoid the waste of material.
Preferred as one, the quantity of described through hole is 5-40, and in a line equidistant arrangement.
The operation principle of this combined type mouth mould: this combined type mouth mould is connected with the head of double screw extruder by link slot, and making the material of double screw extruder melting enter the feed zone of nib liner from conical socket, the material of melting is by forming strip-shaped materials after the depanning section of nib liner.
The present invention has following advantage relative to prior art: this combined type mouth mould improves existing integral type mouth mould, mouth mould being divided into mouthful mould main body and nib liner two major parts.Then in actual production, if when just one or several nib liner deforms, only need strained nib liner to change, and do not need whole mouth mould to change, thus reduce production cost, avoid the waste of mouthful mould.Meanwhile, when a few nib liner deforms, can change in time, thus avoid the presentation quality of nib liner deformation effect plastic pellet, also avoid causing the situation generation of producing and having some setbacks simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1
A kind of combined type mouth mould as shown in Figures 1 to 4, comprise a mouthful mould main body 1, the feed side end face 2 of described mouth mould main body 1 is connected with extruder head, described feed side end face 2 is provided with link slot 3, be provided with through hole 4 bottom described link slot 3, and described through hole 4 internal fixtion is provided with the nib liner 9 of coupling corresponding to the size of through hole 4.The combined type mouth mould of the present embodiment is applied to double screw extruder.
Preferred as one, described nib liner 9 is fixedly installed in through hole 4 by interference fit.The fixed installation mode of interference fit can facilitate the installation or removal of nib liner 9.
Preferred as one, described nib liner 9 comprises columnar depanning section 91 and trumpet-shaped feed zone 92, and described feed zone 92 nib aperture is greater than the nib aperture of depanning section 91, and the charging end face of feed zone 92 is provided with the first inclined plane 93.
Preferred as one, the depanning section 91 external diameter size of described nib liner 9 is 5mm.
