Abstract

The invention relates to a mold for manufacturing a wood-plastic floor. The mold comprises a mold body, a casing, a flow-resisting rod and a flow-limiting cover, wherein one end of the flow-resisting rod is connected to a raw material inlet of the mold body through a fixing body; the other end of the flow-resisting rod stretches out of a raw material outlet of the casing; one end of the flow-limiting cover is in seamless connection with the raw material inlet, and the other end of the flow-limiting cover is in seamless connection with the raw material outlet; a reducing channel is formed inside the flow-limiting cover; the mold further comprises a flow-guiding portion which is an assembly of at least two types of oblique faces. According to the mold, the flow-guiding portion is arranged on the end face, facing towards the reducing channel, of the fixing body, and various types of oblique faces form the guiding portion, so that a raw material is divided into a plurality of strands before the raw material enters a mold cavity, and a plurality of guiding directions appear; and converging flows are generated among different strands of the raw material, and different strands of raw materials interpenetrate mutually at adjacent positions, so that the problem of flowing directions of the raw material is remarkably improved, and the problem that the upper layer of the wood-plastic floor corresponding to a hollow structure can crack easily is finally solved.

Description

A kind of mould for the manufacture of Wood-plastic floor
Technical field
The present invention relates to a kind of mould, especially a kind of mould for the manufacture of Wood-plastic floor.Belong to the extrusion die technical field of Wood-plastic floor.
Background technology
Wood-plastic composite panel is a kind of green material made primarily of material based on timber (lignose, plant cellulose) heats extrusion molding through die apparatus after mixing with thermoplastic macromolecule material (PE plastics), processing aid etc. again.Have performance and the feature of timber and plastics concurrently, timber and plastics can be substituted in a lot of occasion.
Die methods congruent melting is now extruded, and is to produce the simplest method of such material, and its cost is also lower, is applicable to large production.As a rule, Wood-plastic floor inside has some hollow structures, and the non-hollow part of such Wood-plastic floor inside constitutes reinforcement on the contrary, constitutes support bar, not only saves material, can also improve intensity.But problem is also following, and the Wood-plastic floor upper strata corresponding to hollow space becomes a thin layer, and this thin layer is very easy to crack.
Summary of the invention
The present invention will solve the problem, thus provides a kind of mould for the manufacture of Wood-plastic floor.
The technical scheme that the present invention solves the problem is as follows:
For the manufacture of a mould for Wood-plastic floor, comprise the die ontology being shaped with feed(raw material)inlet, the clamshell being shaped with material outlet, choked flow bar and current limliting cover; Described choked flow bar one end is connected to the feed(raw material)inlet place of described die ontology by fixed body, the other end stretches out from the material outlet of clamshell; Described current limliting cover one end and the seamless connection of described feed(raw material)inlet, the other end and described material outlet seamless connection; Described feed(raw material)inlet is greater than described material outlet, makes described current limliting cover inside form a tapered channels; Also comprise diversion division, described diversion division is the set at least two kinds of inclined-planes, is formed by the end face of described fixed body towards described tapered channels or be fixed at least two kind end face attachments of described fixed body towards the end face of described tapered channels.
The Wood-plastic floor upper strata why hollow structure is corresponding is very easy to crack, and entangling its reason is method problem.During die methods congruent melting extrusion Wood-plastic floor, hollow structure be produced, a shaft must be had to be arranged on mould inside, occupy certain space, thus avoid the raw material of congruent melting state to fill up the extrusion of mould, then produce solid floor.As everyone knows, this shaft groundlessly can not be suspended in mould inside, therefore also needs to arrange fixture at mould mouth or mould inside, for being fixed by this shaft.As for above-mentioned crackle Producing reason, just there is very large relation with this fixture.Suppose not have fixture, the raw material of so congruent melting state, will be very steady from entering mould to depanning, Wood-plastic floor also would not occur previously described crackle in use.Fixture exists after all, it hinders the flowing of the raw material of congruent melting state, raw material is from fixture described in the both direction pile warp of left and right, and final to flow from left and right both direction, and these two strands of raw materials of stream can not cross again each other, just collection is combined together abreast, is equivalent to create an implicit crackle.Again due to thickness low LCL, therefore usually crack in use.Product quality is caused significantly to decline.
The present inventor, after having found the problems referred to above, has proposed technique scheme.Though crackle produces because of fixture, fixture still cannot be abandoned.And the inclined-plane of diversion division, the flow regime of the raw material of mould inside can be changed, make to produce between different stock raw material to conflux, infiltrate each other at adjacent between different raw materials, significantly improve the state of PARALLEL FLOW originally, thus solve the problem producing implicit crackle.Therefore, the enforcement of technique scheme of the present invention, the Wood-plastic floor upper strata that hollow structure is corresponding, no longer cracks under normal use.
As preferably, forming the inclined-plane of described diversion division, is vertical slope.
As preferably, form the inclined-plane not of the same race of described diversion division, rational height is different.
As preferably, neighbouring inclined-plane, symmetrically shape.
As preferably, also comprise and be arranged on feed(raw material)inlet place for connecting the connector of adjacent choked flow bar.
As preferably, described choked flow bar has multiple, and multiple described choked flow bar is arranged on sustained height layer.
As preferably, the length that described choked flow bar stretches out described material outlet is not less than the length of described tapered channels.
As preferably, the thickness of described clamshell is greater than the thickness of described die ontology.
As preferably, the gap of adjacent choked flow bar is less than the width of described choked flow bar itself.
As preferably, the both sides of described feed(raw material)inlet are also provided with choker bar.
In sum, the present invention has following beneficial effect:
The present invention is by arranging diversion division at fixed body towards the end face of described tapered channels, and diversion division is arranged to multiple inclined-plane, thus make raw material be divided into multiply when entering mold cavity, produce multiple guiding, produce between the raw material of different stock and conflux, the raw material of different stock infiltrates each other at adjacent, thus significantly improve raw material flow to problem, finally solve the problem that Wood-plastic floor upper strata corresponding to hollow structure is very easy to crack.
