Abstract
The utility model relates to tire production equipment, in particular to a large prefabricated mouth type of a tire crown extruder provided with a small prefabricated mouth type of antenna glue. The large prefabricated mouth type comprises a large prefabricated mouth type (1) of a tire crown extruder, which is provided with a crown glue passage (11), left and right wing glue passages (12) and an antenna glue passage (13). A crown glue outlet (14) of the large prefabricated mouth type (1) is provided with a small prefabricated mouth type (2) of the antenna glue, which communicates with the outlet of the antenna glue passage (13), can block local parts of the crown glue outlet (14), can increase the extrusion pressure of the antenna glue, and is provided with a large inlet and a small outlet. The large prefabricated mouth type of the tire crown extruder can effectively solve the problems that the extrusion pressure of the antenna glue is insufficient and the extrusion pressure of the tire crown is excessive, has the advantages that the produced antenna glue on the tire crown is not covered by the crown glue, the performance of static discharge of a made tire is good, and the tire crown is convenient to produce and process, and fills a blank in the manufacturing industry of tires.
Description
Technical field
The utility model relates to tire production equipment, particularly a kind of crown extruder die.
Background technology
Antenna glue is set on the tyre crown can plays the effect of discharging static in the vehicle traveling process at any time, for a long time, my company comes the making antenna crown with the method for adjusting shape of the mouth as one speaks shape, because the extrusion pressure deficiency of antenna glue, crown glue extrusion pressure is excessive, the crown of producing has the thick hat glue of one deck 0.5-1.0mm that antenna glue is covered, antenna glue can not be exposed, tire does not temporarily have the electrostatic discharge performance, have only tire to use that layer hat glue that covers on the antenna glue after a period of time to grind off the effect that rear tyre just can play discharging static, this shape of the mouth as one speaks each shape of the mouth as one speaks before producing crown all needs secondary operations, and processing is got up very loaded down with trivial details.
Summary of the invention
The antenna glue that the purpose of this utility model provides on a kind of crown that can effectively solve antenna glue extrusion pressure deficiency, produce can be by the hat big pre-die of crown extruder that glue covers, the production and processing crown is provided with the little pre-die of antenna glue easily.
Technical solution of the present utility model is: it comprises the big pre-die of crown extruder with hat glue passage, left and right glue passage and antenna glue passage, the hat gel outlet of big pre-die is provided with the part that is connected with the outlet of antenna glue passage and can blocks the hat gel outlet, and import is big, the outlet I is with the little pre-die of antenna glue of the extrusion pressure that increases antenna glue.
Technique effect of the present utility model is: it can effectively solve antenna glue extrusion pressure deficiency, the problem that crown glue extrusion pressure is excessive, the antenna glue that has on the crown of producing can not covered by hat glue, made tire electrostatic discharge performance is good, the production and processing crown is advantage easily, by little pre-die the pressure of antenna glue is increased, produce antenna (conducting electricity very well) sizing material that has electrostatic discharge at the tyre crown position, good sizing material exposes on the tyre crown to make conductive effect, make it fully to contact with ground, at any time electrostatic dischargedly falling of producing, make the vehicle in travelling not preserve static, security performance is better, by the phenomenon that shocks by electricity, improved the comfortableness when taking when reducing people's ride-on vehicles, it has filled up the manufacturing blank of tire.
Little pre-die is installed on the big pre-die by certain angle, the antenna sizing material is pressurizeed after by little pre-die, make the sizing material pressure that comes out from little pre-die greater than the sizing material pressure that comes out from big pre-die, pressure is consistent when guaranteeing antenna glue like this and being preced with two kinds of sizing materials of glue to come out, and makes hat glue and antenna glue form good interface.
The consistent effect of pressure when it has reached hat glue with antenna gel outlet type reduces antenna glue and is preced with the phenomenon that glue covers, and improves finished product tire antenna exposing ratio, improves antenna tire electrostatic discharge effect.
Description of drawings
Fig. 1 is the utility model embodiment shape of the mouth as one speaks stereogram;
Fig. 2 is the little pre-die stereogram of the utility model embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, it comprises the big pre-die 1 of crown extruder with hat glue passage 11, left and right glue passage 12 and antenna glue passage 13, the hat gel outlet 14 of big pre-die 1 is provided with the part that is connected with the outlet of antenna glue passage 13 and can blocks hat gel outlet 14, and import is big, the outlet I is with the little pre-die 2 of antenna glue of the extrusion pressure that increases antenna glue.
The little pre-die 2 of antenna glue comprises fixed base plate 21, and fixed base plate 21 is provided with to the recessed opposite side protrusion of fixed base plate 21 1 sides, gradually by shallow wide half funnel-form antenna glue groove 22 to narrow dark variation.The shallow wide side of antenna glue groove 22 is for advancing the glue side, and narrow dark side is a glue-extruding side.The narrow dark side of the little pre-die 2 of antenna glue is blocked the position of hat gel outlet 14, is exactly the position that antenna glue belt strip forms.Half funnel-form antenna glue groove, 22 structures can make antenna glue pressure in the process that is extruded increase, thereby making antenna glue sizing material go out little pre-die aft antenna shape forms, shape remains unchanged after waiting to be preced with glue sizing material export-oriented, and guarantee that the antenna sizing material exposes, do not covered by hat glue, sulfuration back finished product the form of the foetus shape is constant substantially.
The little pre-die 2 of antenna glue is embedded on the big pre-die 1 during use, big pre-die 1 is installed on the shape of the mouth as one speaks framework, shape of the mouth as one speaks framework is installed in crown extruder framework front, plate drops on shape of the mouth as one speaks framework and big pre-die front, make each parts form one, sizing material can change direction during by little pre-die under screw rod extruding can change shape again, and this design is suitable for two compound above extruders.
By the installation of the little pre-die 2 of antenna glue, changed the intensity that each shape of the mouth as one speaks spot welding is repaired, install, dismantle very easy.The former shape of the mouth as one speaks goes out the antenna fetal position fixes, and now, can be as required, the mobile shape of the mouth as one speaks can form antenna at any position of tyre crown, has flexibility, before being much better than.
In use, the shape of the mouth as one speaks and little pre-die position contacting go out the position of antenna exactly.
In addition, for prolonging little pre-die service life, finish the back at the little pre-die of processing, need quenching.
