Abstract
The utility model relates to a vacuum out-filmed coextrusion mold, which comprises a mold, the mold is provided with a middle sleeve and an inner sleeve, two flow passages are arranged among the mold, the middle sleeve and the inner sleeve, the flow passages form an outlet through an extrusion die, a vacuum unit communicated with an inner tube is connected with the back side of the mold, the vacuum unit is provided with a vacuum cartridge, the vacuum cartridge is provided with an interface for vacuum pump, an adjustment valve and a vacuum display. One end of the vacuum cartridge is connected with the back side of the mold while the other end is provided with an inner hole for accommodating the inner tube to pass through, the end of which is provided with a sealing ring, the sealing ring is externally provided with a pressing ring which is connected with the vacuum cartridge through a bolt. When an outer plastic wrapped on the inner tube is released from the mold, the outer plastic can be tightly wrapped on the inner tube under the uniform pressure of atmosphere due to that the plastic inner tube of the utility model is in vacuum condition, so that the degluing and uneven adhering problem easily caused between an outer plastic layer and the inner tube can be solved and product quality can be assured.
Description
Technical field
The utility model relates to the tube forming mould in a kind of plastic pipe cutting machining center, relates in particular to a kind of outer coextruding die that covers that adopts the vacuum principle.
Background technology
In the process of producing multiple tube; the outer mould that covers of prior art; its outer plastic layer is to be coated on successively on the interior pipe by two molds with outer glue-line; because inner glue layer is thinner; make complex manufacturing; operating difficulties, therefore in Guan Jing cover outward usually can produce behind the mould coating plastic come unstuck, bonding unequal situation.Analyze its reason: the one, outer plastic layer is exerted pressure because of no external force after breaking away from mould, and outer plastic layer and interior pipe can't be guaranteed to fit tightly, and just may produce degumming phenomenon; The 2nd, outer plastic layer is thicker, produce sagging because of its gravity effect behind the disengaging mould, though interior like this pipe upside is with mould outward can close adhesion, but interior pipe downside break-off can occur with moulding outward, produce bonding inequality thus, thereby product quality can't guarantee, so that influences the continuous ordinary production of multiple tube.
Summary of the invention
The utility model main purpose is: overcome the deficiencies in the prior art, thereby develop bonding evenly, the External review vacuum coextrusion die closely of a kind of inner and outer pipe layer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of External review vacuum coextrusion die, has die body, cover and interior cover in having in the die body, it is characterized in that: described die body, middle cover and interior inner room are provided with two runners, and described runner through port mould forms outlet; Described die body rear side is connected with the vacuum plant that is connected with interior pipe.Between die body and middle cover, plastic passages is arranged, between middle cover and interior cover, the glue runner is arranged.
Technique scheme of the present utility model can also be further perfect, and as preferably, described vacuum plant has vacuum cylinder, and vacuum cylinder is provided with vavuum pump interface, control valve and vacuum display device.
As preferably, the connecting plate of described vacuum cylinder one end is connected with bolt with the die body rear side; The other end of vacuum cylinder have hold in the endoporus that passes through of pipe, end face is equipped with sealing ring, trim ring is equipped with in described sealing ring outside, adopts screw to be connected between described trim ring and the vacuum cylinder.The square connecting plate of vacuum equipment (indent) links to each other with bolt with the square end of die body.
Therefore, advantage of the present utility model is: because plastic inner pipe forms vacuum, when outer the moulding behind mould that coats on inner pipe, under the uniform pressure of atmosphere, closely coat on inner pipe, come unstuck and bonding uneven problem thereby solved to be easy to generate between outer plastic layer and the interior pipe, guaranteed product quality.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
External review vacuum coextrusion die
External review vacuum coextrusion die as shown in Figure 1 comprises outer cover coextruding die and vacuum plant.Cover coextruding die outward and comprise the die body 6 that links to each other with mould bases, cover 5 in having in the die body, cover 4 in having in the middle cover, there is mouthful mould 8 front, on mouthful mould adjustment seat 7 is arranged.Between die body 6 and middle cover 5 plastic passages is arranged, between middle cover 5 and interior cover 4 the glue runner is arranged, runner through port mould 8 is compound with plastics and glue, realizes the plastic cement co-extrusion.Vacuum plant comprises vacuum cylinder 11, and vavuum pump interface 10 is equipped with vacuum display device 2 on the vacuum cylinder, control valve 3.The square connecting plate (indent) of vacuum cylinder 11 1 ends links to each other with bolt with the square end of die body; The other end of vacuum cylinder 11 has pipe 9 endoporus that pass through in the appearance, and end face has sealing ring 1, and there is trim ring 12 the sealing ring outside, adopts the screw connection, makes it to form sealing surface.During use, after interior pipe 9 penetrates vacuum plant and mould, open vavuum pump, form vacuum at the vacuum cylinder inner chamber, its vacuum can be regulated and shows vacuum values with vacuum meter by control valve 3, outer like this moulding under the uniform pressure at atmosphere behind the mould closely coats on inner pipe, thereby solved the outer the problems referred to above that break away from easily with interior pipe of moulding.
