Technical field

This utility model is related to a kind of plastic extrusion coating mould, more particularly to the tubing outer cladding mould with chiller Tool.

Background technology

Plastic extrusion is that, using the plasticity of plastics, the extrusion molding of plastics is mainly completed in mould inside.Using pressure Power, the runner molding between the mouth mold of mould and core will be clamp-oned through the plastics of hot melt.And tubing is being entered using plastic extrusion During row cladding, the plastics of heat easily make tubing thermal deformation or soften cracking, when particularly coating to winding pipe, also make skeleton Pipe melts or deforms, and the ring stiffness for causing winding pipe changes, and is easier tubing because being subject to external pressure or internal pressure And cause to deform or rupture.

Utility model content

Task of the present utility model be to provide a kind of simple structure, can reduce tubing outer cladding temperature of charge with cold But the tubing outer cladding mould of device.

To solve above-mentioned technical problem, this utility model provides a kind of tubing outer cladding mould with chiller, bag Include mold, mouth mold, core, chiller；The mold is provided with opening, and the mouth mold is installed at the opening, institute State core to be arranged in the mould body and through the mouth mold, the mold, mouth mold and core surround a runner jointly；Institute State chiller to be arranged in the core, and the colling end of the chiller is located at the exit of the runner.

Preferably, the chiller is provided with intake tunnel and exhalant canal.

Preferably, the intake tunnel and exhalant canal are all helical groove structure.

Preferably, the core includes core end and the core body in the exit for being located at runner, the thickness of the core end Thickness of the degree less than the core body.

Preferably, the chiller includes colling end and cooling body, and the outer surface of the colling end fits in the core The inner surface of mould end.

Preferably, the colling end extends the core end.

Preferably, it is provided with heat insulation loop between the cooling body and the core body.

Preferably, it also includes for feeding and is provided with the aptamers of through hole, and the aptamers are fixed on the runner one Hold, and through hole is interconnected with the runner.

Preferably, the chiller is provided with the through hole passed through for tubing.

Compared to a kind of tubing outer cladding mould with chiller that prior art, this utility model are provided, pass through Chiller is set in core, temperature of the fluid as external coating at runner exit reduced, in advance to external coating Inwall cooled down, coat tube surfaces when will not make surface thermal deformation or soften cracking.Particularly in cladding winding pipe Skeleton pipe when, external coating is conducted to the shortage of heat of skeleton pipe to cause casing play to deform or soften cracking, solves The problem of the pre- thermal deformation of skeleton pipe and softening cracking, is effectively improved tubing outward appearance when traditional wound pipe is coated, and reduces due to skeleton The risk that pipe melts and causes ring stiffness to change, is particularly suited for structure wall winding tube Type B pipe.This utility model simple structure is closed Reason, effect is significant.

Description of the drawings

Technical scheme in order to be illustrated more clearly that this utility model embodiment, below to wanting needed for embodiment description The accompanying drawing for using is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, right For those of ordinary skill in the art, on the premise of not paying creative work, can be obtaining it according to these accompanying drawings His accompanying drawing, wherein：

Fig. 1 is a kind of profile of the tubing outer cladding mould with chiller of this utility model.

Specific embodiment

The technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in this utility model, The other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, belongs to this practicality new The scope of type protection.

Please refer to Fig. 1, Fig. 1 is a kind of section of the tubing outer cladding mould with chiller of this utility model Figure.

This utility model provides a kind of tubing outer cladding mould with chiller, including mold 10, mouth mold 20, core Mould 30, chiller 40；Mold 10 is provided with opening, and mouth mold 20 is installed at the opening, and core 30 is arranged at mold In 10 and through mouth mold 20, mold 10, mouth mold 20 and core 30 surround a runner 50 jointly；Chiller 40 is arranged at core In 30, and the colling end 41 of chiller 40 is located at the exit of the runner.By arranging chiller 40 in core 30, Temperature of the fluid at runner exit as external coating is reduced, the inwall of external coating is cooled down in advance, in cladding Surface thermal deformation will not be made during tube surfaces or softens cracking.Particularly when the skeleton pipe of winding pipe is coated, external coating is passed The shortage of heat to skeleton pipe is led to cause casing play to deform or soften cracking, skeleton pipe when traditional wound pipe is coated is solved Pre- thermal deformation and the problem of softening cracking, are effectively improved tubing outward appearance, reduce causing ring stiffness to change because skeleton pipe melts Risk, be particularly suited for structure wall winding tube Type B pipe.

Chiller 40 is provided with intake tunnel 43 and exhalant canal 44, and using water as coolant reduces the temperature of core Degree.

Intake tunnel 43 and exhalant canal 44 are all helical groove structure, and water can be made to touch inside bigger chiller Area, improves cooling effectiveness.

Core 30 includes the core end 31 in the exit for being located at runner and core body 32, and the thickness of core end 31 is less than core The thickness of body 32, the plastic liquid of mould is extruded by core end 31, when core end 31 thickness than it is relatively thin when, can Accelerate heat transfer of the colling end 41 of chiller 40 to core end 31, improve the cooling of plastic liquid at runner exit.And The thickness of core body 32 when then plastic liquid flows through core body, is difficult to be cooled, so as to ensure plastics more than the thickness of core end 31 Flowing velocity of the fluid in mould body.

Chiller 40 includes colling end 41 and cooling body 42, and the outer surface of colling end 41 fits in the interior of core end 31 Surface, can accelerate heat transfer of the colling end 41 of chiller 40 to core end 31, improve plastic liquid at runner exit Cooling.

Colling end 41 extends core end 31, and behind core end 31, material heat transfer, temperature drops plastic liquid It is low, colling end 41 is passed through, directly contact with colling end 41, further reduce plastic liquid temperature.

Heat insulation loop 70 is provided between cooling body 42 and core body 32, the heat transfer between cooling body 42 and core body 32 is reduced, Reduction plastic liquid flows through temperature change during core body 32, it is ensured that flowing velocity of the plastic liquid in mould body.

The tubing outer cladding mould that this utility model is provided can also include for feeding and be provided with the aptamers 60 of through hole, Aptamers 60 are fixed on the one end of runner 50, and through hole is interconnected with runner 50.

Chiller 40 is provided with the through hole 45 passed through for tubing.

The plastics of melting are extruded from extruder, into the through hole of aptamers 60, through runner 50, from mouth mold 20 and core 30 Gap flow out the plastic melt of Jing chillers cooling, be coated on the outer surface of tubing, be applied to be coated on during winding pipe On its skeleton pipe.

Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, it is every using this Equivalent structure or equivalent flow conversion that bright description and accompanying drawing content are done, or directly or indirectly it is used in other related skills Art field, is included in the same manner in the scope of patent protection of the present invention.
