Ask..The present invention designs windscreen manufacture method in a kind of bullet train group annular, uses the internal windscreen of injection molding mode to carry out
Sulfidization molding, the performance of interior windscreen after molding can be improved, and process of injection molding is simple, improves production efficiency, saves and produces into
This, can extensively apply.
Summary of the invention
The purpose of the present invention is aiming at the deficiency that prior art exists, it is provided that windscreen in a kind of bullet train group annular
Manufacture method, uses the internal windscreen of injection molding mode to carry out sulfidization molding, produces windscreen product in annular thin wall, be injected into
Type process is simple, improves production efficiency, saves production cost, it is possible to resolve in prior art windscreen compression molding inefficiency and
The problem that properties of product are the highest.
The present invention provides windscreen manufacture method in a kind of bullet train group annular, comprises the steps:
(1) cut glue: first rubber is cut, be cut into the material block of predetermined weight；
(2) plasticate: open banbury, the rubber cut is put into banburying chamber plasticate in step (1), process of plasticating
In, closed-smelting machine rotor and machine wall cooling to be passed through water, it is ensured that sizing material temperature is below 60 DEG C, after the time of plasticating arrives, by sizing material from
Banbury is poured out, the thinnest logical twice, the volume of lower one-tenth standard weights；
(3) mixing: the sizing material plasticated in step (2) to be put into banburying in banbury, joins load weighted the most in batches
Mixture, i.e. age resistor, activating agent, white carbon black, DOS etc. are thrown in into banbury, mixing 5-30min；
(4) adding agent: open mill, the glue stuff compounding discharged by banbury in step (3) puts between mill two roller,
Moulding bag roller, after sizing material bag roller, adds accelerator and sulfur, after accelerator and sulfur are suffered all, turns roll spacing down, sizing material is made a call to three
Angle is wrapped twice, thinner logical twice, use after the bin aging a period of time mixed；
(5) heat refining: by the sizing material that mixes in step (4) through mill heat refining uniformly after, by use requirement by preforming
The material strip of mechanism established practice shaped；
(6) sulfidization molding: by interior windscreen mould matched moulds, be fully warmed-up, make injector material feeding after preheating, note
Penetrate, after injection, under 120-180 DEG C of curing temperature, under 5-35MPa sulfide stress, vulcanize 30-100min, sulfidization molding；
(7) deburring: after interior windscreen mould die sinking, by windscreen finished product in the annular thin wall after sulfidization molding in step (6) first
Park, after being cooled to room temperature, carry out deburring arrangement, unnecessary sizing material and irregular glue limit are repaired neat, clean and tidy.
As the further improvement of technical solution of the present invention, in described step (6), the preferably the highest locked mode pressure of injector
For 2400t, injection pressure is 100-400MPa, it is ensured that sizing material can be flowed in the die cavity of mould smoothly, prevents compound viscosity
The long note of excessive or runner is discontented with die cavity.
As the further improvement of technical solution of the present invention, in described step (6), owing to interior windscreen mould is bigger, interior
Shape size is complicated, and preferably sizing material uses the mode of injector injection, and interior windscreen mould is evenly equipped with 6-24 hole for injecting glue, makes sizing material
The die cavity of interior windscreen mould, and mix homogeneously can be quickly filled with.
Accompanying drawing explanation
Accompanying drawing 1 be the present invention bullet train group annular in windscreen manufacture method flow chart.
Detailed description of the invention
1 the invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1
Windscreen manufacture method in the bullet train group annular of the present invention, specifically includes following steps:
(1) cut glue: first rubber is cut, be cut into the material block of predetermined weight.
(2) plasticate: open banbury, the rubber cut is put into banburying chamber plasticate in step (1), process of plasticating
In, closed-smelting machine rotor and machine wall cooling to be passed through water, it is ensured that sizing material temperature is below 60 DEG C, after the time of plasticating arrives, by sizing material from
Banbury is poured out, the thinnest logical twice, the volume of lower one-tenth standard weights.
(3) mixing: the sizing material plasticated in step (2) to be put into banburying in banbury, joins load weighted the most in batches
Mixture, i.e. age resistor, activating agent, white carbon black, DOS etc. are thrown in into banbury, mixing 5-30min.
(4) adding agent: open mill, the glue stuff compounding discharged by banbury in step (3) puts between mill two roller,
Moulding bag roller, after sizing material bag roller, adds accelerator and sulfur, after accelerator and sulfur are suffered all, turns roll spacing down, sizing material is made a call to three
Angle is wrapped twice, thinner logical twice, use after the bin aging a period of time mixed.
(5) heat refining: by the sizing material that mixes in step (4) through mill heat refining uniformly after, by use requirement by preforming
The material strip of mechanism established practice shaped.
(6) sulfidization molding: by interior windscreen mould matched moulds, being fully warmed-up, after preheating, sizing material is by injector screw rod material feeding,
By screw of injection to interior windscreen mould, in mold runner is expelled to dies cavity；The highest locked mode pressure of injector is
2400t, injection pressure is 100-400MPa, it is ensured that sizing material can be flowed in the die cavity of mould smoothly, prevents compound viscosity mistake
Big or the long note of runner is discontented with die cavity；Owing to interior windscreen mould is bigger, interior shape size is complicated, and injector uses twin screw injection
Mode, and interior windscreen mould is evenly equipped with 6-24 hole for injecting glue, enables sizing material to quickly fill with the die cavity of interior windscreen mould, and
Mix homogeneously；After injection, under 120-180 DEG C of curing temperature, under 5-35MPa sulfide stress, vulcanize 30-100min, sulfuration
Molding.
(7) deburring: after interior windscreen mould die sinking, by windscreen finished product in the annular thin wall after sulfidization molding in step (6) first
Park, after being cooled to room temperature, carry out deburring arrangement, unnecessary sizing material and irregular glue limit are repaired neat, clean and tidy.
The invention has the beneficial effects as follows: the method uses injector and special dies, internal by injection molding mode
Windscreen carries out sulfidization molding, the performance of interior windscreen after can improving molding.Compared with the interior windscreen of conventional moulded molding, injection moulding
Interior windscreen hot strength at least improve 2MPa, elongation at break improves more than 80%, fatigue performance improve at least 40% with
On；And windscreen in using injection system to produce, process of injection molding is simple, improves production efficiency, saves production cost, has higher
Using value.
The present invention is not limited to above-mentioned detailed description of the invention, according to foregoing, according to the ordinary technical knowledge of this area
And customary means, without departing under the present invention above-mentioned basic fundamental thought premise, the present invention can also make other various ways
Equivalent modifications, replace or change, belong to protection scope of the present invention.
