The different location of the feed plate is arranged in mouth, soft material feed inlet；In the channel that hard material and soft material pass through compression plate respectively by
Compression finally merges in the outlet of fusion profiled sheeting, obtains soft or hard integrated soft and hard seal adhesive tape and melt base.
The hard material and channel of the soft material in feed plate are current stabilization channel, and sectional dimension does not change.
The soft and hard seal adhesive tape is melted base and is towed in cooling water tank from the outlet of fusion profiled sheeting, the water tank
3~5 pieces of cooling and shaping blocks of middle setting, the cooling and shaping block to soft and hard seal adhesive tape melt base carry out cooling and shaping, make its at
For soft and hard seal adhesive tape.
The water tank is connect with recirculating cooling water system.
Hard material inner cavity air inlet and soft material inner cavity air inlet are set on the co-extruding mould, and respectively with hard material and soft material
Cavity connection.
The hard material feed inlet, soft material feed inlet are connect with hard material coextrusion and soft material coextrusion respectively；It is described
The hard material coextrusion unit time feed quantity be greater than soft material coextrusion.
The present invention by adopting the above technical scheme, produces soft-hard coextrusion sealing joint strip, and the sealing improved between profile and glass is imitated
Fruit, while guaranteeing the production capacity of profile and the qualification rate of product.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
The structure of the invention as shown in Fig. 3 to Fig. 7 is a kind of sealing joint strip soft-hard coextrusion mold, belongs to sealing joint strip and squeezes
The technical field of molding die out is related to the design principle of the soft-hard coextrusion mold of sealing joint strip extrusion molding mould.
In order to overcome the drawbacks of the prior art and there are the problem of, realize production soft-hard coextrusion sealing joint strip, raising type
The goal of the invention of sealing effect between material and glass, the technical scheme adopted by the invention is as follows:
As shown in figure 8, the sealing joint strip is divided into the hard material part and soft material portion to link into an integrated entity on its cross section
Point, hard material part is got into the adhesive tape groove of profile.In this way, the hard material part of adhesive tape is stuck in adhesive tape groove, so that adhesive tape groove is not
It is easy to fall off；The soft material part of adhesive tape reliably seals forms.
As shown in Fig. 3 to Fig. 7, sealing joint strip soft-hard coextrusion mold of the invention, including feed inlet 1, the charging of soft material are expected firmly
Mouth 2, the co-extruding mould set gradually feed plate 3, compression plate 4 and fusion profiled sheeting 5；The hard material feed inlet 1, soft material
The different location of the feed plate 3 is arranged in feed inlet 2；It is compressed respectively in the channel that hard material and soft material pass through compression plate 4,
It is finally merged in the outlet of fusion profiled sheeting 5, obtains soft or hard integrated soft and hard seal adhesive tape and melt base.
The runner of soft or hard material independent design on mold, it is non-interference.Sealing joint strip soft-hard coextrusion mold of the invention
Purpose is production soft-hard coextrusion sealing joint strip as shown in Figure 8, can be improved the sealing effect between profile and glass, while not shadow
The production qualification rate for ringing profile, guarantees that it has certain production capacity.
The hard material and channel of the soft material in feed plate 3 are current stabilization channel, and sectional dimension does not change.
After soft or hard material enters the feed plate 3 of mold, the current stabilization in feed plate 3, and enough pressure is maintained to mold
Compression plate feed；Material is compressed in the compression plate 4 of mold, so that material compacting, is carried out for the fusion molding of product
Prepare；When material enters the fusion profiled sheeting 5 of mold after, further stablize in fusion profiled sheeting 5, so that soft material and expecting firmly
Flow velocity keeps synchronous, balance, finally merges in the outlet end of fusion profiled sheeting 5, the soft and hard seal adhesive tape of shape needed for obtaining is melted
Base.
The soft and hard seal adhesive tape is melted base and is towed in cooling water tank from the outlet of fusion profiled sheeting 5, the water
3~5 pieces of cooling and shaping blocks 8 are set in case, and the cooling and shaping block 8 melts base to soft and hard seal adhesive tape and carries out cooling and shaping, makes
It becomes soft and hard seal adhesive tape.
The water tank is connect with recirculating cooling water system.The soft and hard seal adhesive tape of acquisition is melted embryo to be drawn to circulation
The cooling and shaping block that 3~5 groups are placed in the water tank of water, in water tank, mainly carries out shaping fixation to critical size, it is ensured that obtains institute
Need the soft and hard seal adhesive tape of size.
Hard material inner cavity air inlet 6 and soft material inner cavity air inlet 7 are set on the co-extruding mould, and respectively with hard material and soft
The cavity of material is connected to.
According to the design feature of adhesive tape, closed inner cavity needs to design gas circuit, hard material inner cavity as shown in Figure 3 and Figure 7 into
Port 6 and soft material inner cavity air inlet 7, by adjusting charge air flow, so that the full molding of cavity.
The hard material feed inlet 1, soft material feed inlet 2 are connect with hard material coextrusion and soft material coextrusion respectively；Institute
The feed quantity for the hard material coextrusion unit time stated is greater than soft material coextrusion.
Independent feed is carried out to two feed inlets of the feed plate of mold respectively using two coextrusions, two co-extrusions are set
It is injected separately into the soft or hard material of different formulations in standby, realizes the soft-hard coextrusion of sealing joint strip.The production capacity of hard material co-extrusion machine is larger, soft
Expect that the production capacity of co-extrusion machine is smaller, mainly considers the production capacity and mobility of soft or hard material.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
