Description

A kind of two-tube mould of tubing

Technical field

This utility model relates to mould applications, refers more particularly to a kind of two-tube mould of tubing.

Background technology

Originate in when current two-tube extruder produces the minor caliber pipes such as PVC electrician's pipe, feed pipe and can be respectively 70-100kg/ The industry level of h, domestic PVC pipeline industry production dog-eat-dog, this production capacity causes the cost of product higher, it is impossible to go together Industry producer competes, and then company proposes a plan, engineering department take the lead, and tissue produces, and designs and develops personnel's lifting to production capacity Repeatedly have a meeting investigation, plasticizing can be caused when promoting production capacity not enough through discussing the used two-tube mould of discovery company and cause product Quality is unable to reach requirement, under the cooperation of technique and formula, though quality is improved, but still is unable to reach standard, and formula becomes This raising is more, and the another quality of production is the most unstable.

Utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art to provide a kind of simple in construction, matter The two-tube mould of tubing that amount is stable, production efficiency is high.

This utility model realizes in the following way:

A kind of two-tube mould of tubing, including the neck part 1 being arranged on cross-head 20；Described neck part 1 is connected to mould On general laws orchid 2；Connected by screw 3 on described mould flange 2 and have shunting body 6；Be provided with in described shunting body 6 two Dao Huo bis-roads with On sub-runner 61；Described sub-runner 61 is connected with cross-head 20；The corresponding one group of extrusion shaping machine of per pass sub-runner 61 Structure, it is characterised in that: described extrusion molding mechanism includes that internal ring 8, connecting plate 9, described connecting plate 9 are connected by screw in shunting On body 6, described connecting plate 9 is connected by screw die sleeve 10；Described internal ring 8 is located on die sleeve 10, and internal ring 8 is positioned at connection On the interior annular distance of plate 9；It has been connected by screw mould bases 12 on described die sleeve 10；Connect on described mould bases 12 and have external mold 19；Described External mold 19 is that sphere is connected 21 with the junction of mould bases 12；Described mould bases 12 is provided with tip 15；Connect on described tip 15 and have The die cavity that internal ring 8, die sleeve 10, mould bases 12, external mold 19 are formed by core rod 18, described tip 15 and core rod 18 separates inner flow passage 101；Described inner flow passage 101 communicates with sub-runner 61.

The beneficial effects of the utility model are: optimize inner flow passage structure, make runner more smooth and easy；Mould bases strengthens, material Inside the holdup time lengthens and adds the compression ratio of mould, makes back pressure strengthen, thus improves the plasticizing capacity of mould, product More preferably, better quality, production capacity can significantly be promoted quality also will not be impacted in compacting；Mould lengthens, and extends material and exists Fusion time in mould, increases die pressure, makes plasticizing more preferable, and material base compacting is more preferably；Employing sphere adjustment form, thus more Convenient, more directly；Change mould to regulate the speed soon, and because of the increasing of mould bases, production capacity also has lifting further, and production capacity now can reach 180-250kg/h, thus reduce production cost.

Accompanying drawing explanation

Fig. 1 this utility model structural representation.

Detailed description of the invention

In conjunction with accompanying drawing in detail, this utility model detailed description of the invention is described in detail:

As it is shown in figure 1, a kind of two-tube mould of tubing, including the neck part 1 being arranged on cross-head 20；Neck part 1 is even It is connected on mould flange 2；Connected by screw 3 on mould flange 2 and have shunting body 6；More than two Dao Huo bis-roads it are provided with in shunting body 6 Sub-runner 61；Sub-runner 61 is connected with cross-head 20；The corresponding one group of extrusion molding mechanism of per pass sub-runner 61, extrusion Shaping mechanism includes internal ring 8, connecting plate 9, and connecting plate 9 is connected by screw on shunting body 6, on connecting plate 9 by screw even It is connected to die sleeve 10；Internal ring 8 is located on die sleeve 10, and internal ring 8 is positioned on the annular distance of connecting plate 9；On die sleeve 10 by screw even It is connected to mould bases 12；Connect on mould bases 12 and have external mold 19；External mold 19 is that sphere is connected 21 with the junction of mould bases 12；Set on mould bases 12 There is tip 15；Connecting on tip 15 has core rod 18, tip 15 and core rod 18 internal ring 8, die sleeve 10, mould bases 12, external mold 19 to be formed Die cavity separate have inner flow passage 101；Inner flow passage 101 communicates with sub-runner 61.

This utility model optimizes the structure of inner flow passage 101 and sub-runner 61, makes runner more smooth and easy；Mould bases 12 strengthens, material Inside the holdup time lengthens and adds the compression ratio of mould, makes back pressure strengthen, thus improves the plasticizing capacity of mould, product More preferably, better quality, production capacity can significantly be promoted quality also will not be impacted in compacting.

This utility model inner flow passage 101 and the extended length of sub-runner 61, extend material fusion time in mould, increase Adding die pressure, make plasticizing more preferable, material base compacting is more preferably.

This utility model external mold 19 is that sphere is connected 21 with the junction of mould bases 12, and external mold 19 and mould bases 12 use sphere to adjust Shaping type, thus more convenient, more directly；Change mould to regulate the speed soon.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
