Description
Technical field
The present invention relates to plastic flexible tube extruder, especially relate to a kind of jointing die that is used for plastic flexible tube extruder.
Background technology
The flexible pipe that common plastic flexible tube extruder is extruded all is flexible pipes of same color, and correlated identities in the hose surface printing forms finished product then.Because the product of personation of poor quality is still many, if just on printing mark, make an issue of, then easily by counterfeit.How can effectively false proofly become the problem of very paying close attention in the industry.At present, the flexible pipe that injects distinct color being arranged also in raw making materials, generally is that outer surface at flexible pipe forms and is different from the colo(u)r streak of flexible pipe integral color, though be convenient to difference like this, is prone to imitate, and antifalse effect is limited.In addition, need seal background color earlier during owing to the hose surface printing, and then print required mark look; Therefore the hose surface printing need consume a large amount of printer's inks; How to reduce printing cost and just become important problems, integral surface must stamp background color when common homochromy flexible pipe printed, and cost is higher.
The patent No. is that 200420098772.5 utility model patent provides a kind of plastic flexible pipe to annotate the line mould; Comprise outer die body; Be provided with guide body, interior die body and core rod in the outer die body; The charging aperture of outer die body is communicated with the discharging opening of flexible pipe plastic extruder, and the deflector chute of guide body is communicated with the charging aperture of outer die body, has the annulus that communicates with deflector chute between interior die body and the outer surface that core rod matches; The plastics that the flexible pipe plastic extruder is extruded get into the annulus through deflector chute; Extrude the tube wall that the back forms flexible pipe from the discharge opening of core rod, outer die body is provided with a notes line hole that communicates with notes line plastic extruder at least, this notes line hole be arranged at core rod on and the radial passage that communicates with said annulus communicate.This utility model is simple in structure, is convenient to Operation and maintenance, existing mold is transformed the outer surface that just can be implemented in plastic flexible pipe a little form the lines that are different from the flexible pipe integral color.This patent can only apply the lines that are different from the flexible pipe integral color at the outer surface of plastic flexible pipe; Can't accomplish to be bonded into integral body (a part of tube wall true qualities that are flexible pipe are different with remainder tube wall true qualities) by the raw material of 2 kinds of different true qualities, this is because the structure function of mould is limited.
Summary of the invention
It is different with remainder tube wall true qualities to the purpose of this invention is to provide a kind of a part of tube wall true qualities of flexible pipe that make, and antifalse effect is good and can obviously reduce the jointing die that is used for plastic flexible tube extruder of printing cost.
The present invention is provided with guide core rod, guide die sleeve, discharging die lip and discharging core rod; The material guiding die in-core is provided with steam vent, and the material guiding die core outer surface is provided with guiding gutter, and the guiding gutter rear portion is divided into 2 splitter boxs of isolating each other; The guiding gutter front portion is divided into ring-type interflow groove, and 2 splitter boxs are communicated with 1 charging hole respectively, and the material guiding die cover is enclosed within on the material guiding die core; Guide die sleeve rear end and guide core rod are connected, and the degree of depth of guiding gutter forms the guide gap between guide die sleeve and the guide core rod, and discharging die lip rear end and guide die sleeve front end are connected; Discharging die core back end and guide die core front end are connected; The discharging die lip is enclosed within on the discharging core rod, is provided with the discharging gap between the outer surface of the inner surface of discharging die lip and discharging core rod, and the discharging gap coincide with the guide gap and is communicated with; The discharging mode in-core is provided with steam vent, and the steam vent of discharging core rod is communicated with and and exterior with the steam vent of material guiding die in-core.
Said guide core rod is preferably T font guide core rod, and the rear end boss of guide core rod and the rear end of guide die sleeve are connected.
Be located at the material guiding die in-core for 1 in described 2 charging holes, the import of this charging hole is positioned at guide core rod rear end face, and 1 in the outlet of this charging hole and said 2 splitter boxs is communicated with; In said 2 charging holes in addition 1 be located at material guiding die and put, put at material guiding die and be provided with radially cinclides, cinclides is provided with the charging hollow joint, the hollow hole of charging hollow joint is this charging hole, in this charging hole and said 2 splitter boxs other 1 be communicated with.
Said discharging die lip is preferably the discharging die lip that is provided with tubaeform centre bore, and said discharging core rod is flaring discharging core rod, and said discharging gap is the discharging gap of loudspeaker profile, and the front portion in discharging gap is the flexible pipe forming part.
Said discharging die lip rear end and guide die sleeve front end are connected preferably, and discharging die lip rear end is connected through flange and guide die sleeve front end.
Preferably be provided with the waveform tube seat in the groove of said ring-type interflow.
The area of said 2 splitter boxs can be identical or different.Phase difference between said 2 splitter boxs is preferably 180 °.
Said 2 splitter boxs are communicated with 1 charging hole respectively, and are provided with the concave arc shape dashpot in connection place separately.
Compare with prior art, the present invention has following outstanding advantage and remarkable result:
Because the guiding gutter rear portion is divided into 2 splitter boxs of isolating each other, 2 splitter boxs are communicated with 1 charging hole respectively, like this; The discharging opening that can 2 charging holes be communicated with 1 plastic flexible tube extruder respectively; Can the raw material of 2 kinds of different colours be injected mould through 1 charging hole respectively, 2 kinds of raw materials engage at the groove place, ring-type interflow of guiding gutter forward part then and form integral body earlier through 2 mutual splitter boxs of isolating of guiding gutter rear section; Through the discharging gap, be able to the moulding discharging again.Like this, the tube wall that just can produce by 2 kinds of different true qualities engages the finished product (be white like half tube wall, second half tube wall is a black) that constitutes.
Because the present invention can realize making a part of tube wall true qualities and the remainder tube wall look different purpose of flexible pipe.Can play anti-fake effect more up hill and dale like this.In addition, the present invention can choose the raw material of 2 kinds of colors in advance according to the needs of surface printing mark; The required background color of a part of tube wall true qualities that make flexible pipe and typographic(al) mark is identical; Like this, just only need on this part tube wall, coat edible vegetable oil and get final product, and need not republish background color.Therefore can significantly reduce printing cost.And the background color that does not need a side pipe wall of typographic(al) mark can select for use the lower mass colour of price to print.Thereby integral surface must stamp the requirement of background color earlier when having avoided homochromy flexible pipe to print, and can reach the purpose of remarkable reduction printing cost.This shows that the present invention both can be effectively false proof, can significantly reduce printing cost again.
