Description
Technical field
The present invention relates to the technical field that silicon rubber line squeezes out, specially a kind of new type silicone rubber line squeezes out die sleeve.
Background technique
Mixing silicon rubber process or since friction is mixed into and silicon rubber extrusion equipment aging silicon rubber for a long time in barrel
The impurity not melted squeezes out tubulose silastic surface at head and covers one layer of impurity.After placing traditional dies, squeezing out cable can go out
An existing line, this line not only influences the beauty of cable, and there are unpredictable negative effects to wire and cable.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of new type silicone rubber lines to squeeze out die sleeve, in cable extrusion process,
Mixed impurity is discharged, and keeps extrusion and extrusion performance, guarantees the beauty and quality of product.
A kind of new type silicone rubber line extrusion die sleeve, technical solution are such that it includes connection core portion, connects simultaneously
Cap portion, it is characterised in that: the inner cavity of the connection core portion is taper closing in from the outside to the core, the connection and cap portion
Be provided centrally with centre bore, the centre bore is coupled for mold core boss, the connection and cap portion, connection mold core
A wherein radial position for partial outer ring surface is provided with the discharge slot extended along die sleeve length direction, the discharge slot indent
It is whole in being covered on the corresponding position of the outer ring surface of the connection core portion, connection and cap portion, the discharge slot length direction
The length of a die sleeve, the position alignment head of the discharge slot closes at glue-line during installation.
It is further characterized by: body diameter corresponding to the connection and cap portion is less than the connection core portion
Corresponding body diameter；
The length direction end that the discharge slot corresponds to the connection core portion is provided with oblique export inclined-plane, described
Oblique export inclined-plane is convenient for discharge impurity；
Preferably, the cental axial position alignment head of the discharge slot closes at glue-line during installation.
After applying the present invention, when placing die sleeve, the position alignment head that slot is discharged is closed at glue-line, in extrusion process,
Mixed impurity is discharged by discharge slot, and keeps extrusion and extrusion performance, guarantees the beauty and quality of product.
Detailed description of the invention
Fig. 1 is three-dimensional outer profile structural schematic diagram of the invention；
Fig. 2 is perspective wire frame figure structure schematic representation of the invention；
Title corresponding to serial number is as follows in figure:
Connect core portion 1, connection and cap portion 2, taper closing in 3, centre bore 4, discharge slot 5, oblique export inclined-plane 6.
Specific embodiment
A kind of new type silicone rubber line extrusion die sleeve, is shown in Fig. 1, Fig. 2: it includes connection core portion 1, connection simultaneously cap portion 2,
The inner cavity for connecting core portion 1 is that taper from the outside to the core closes up 3, connects and cap portion 2 is provided centrally with centre bore 4, in
Heart hole 4 is coupled for mold core boss, connect and cap portion 2, connect core portion 1 outer ring surface a wherein radial position
The discharge slot 5 for being equipped with and extending along die sleeve length direction is installed, discharge 5 indent of slot is in connection core portion 1, connection and cap portion
The corresponding position of 2 outer ring surface is discharged the length for covering entire die sleeve on 5 length direction of slot, the position of slot 5 is discharged during installation
Head is directed to close at glue-line.
It connects body diameter corresponding to simultaneously cap portion 2 and is less than body diameter corresponding to connection core portion 1；
The length direction end that discharge slot 5 corresponds to connection core portion is provided with oblique export inclined-plane 6, and oblique export is oblique
Face 6 is convenient for discharge impurity；
It connects and the outer ring surface of cap portion 2 is helicitic texture (be not drawn into figure, belong to existing mature structure), the company of being used for
It connects and cap, in text and cap is specially locking nut structure；
Specifically, the cental axial position alignment head that slot 5 is discharged during installation closes at glue-line, it is ensured that the effect of impurity is discharged
Most preferably.
It specifically has the beneficial effect that:
It is complete if can be very good to squeeze out impurity from discharge slot using such die sleeve 1. ageing equipment causes impurity reason
Transitional function in Cheng Xin used equipment；2. color mixing is bad in mixing process, in extrusion process, this die sleeve can use,
Colour band is discharged by discharge slot.
Specific embodiments of the present invention are described in detail above, but content is only the preferable implementation of the invention
Example, should not be considered as limiting the invention the practical range of creation.It is all to become according to equalization made by the invention application range
Change and improve etc., it shall still fall within the scope of this patent.
