AI Technical Summary
The shape of the composite surface of the existing all-steel tire rubber core cannot be adjusted, resulting in concentrated stress at the sub-mouth, which is prone to early damage. Moreover, when the existing pre-mouth and mouth plates are produced, the soft and hard rubber composite surface cannot be adjusted, and the pre-mouth plate needs to be redesigned.
A fully steel rubber core mouth plate is designed, including the main plate, inner panel and outer panel. The inner panel and outer panel are arranged through the inner and outer panels of the inner and outer panels of different depths to form a splicable runner structure to adjust the shape of the rubber core extruded from the extrusion outlet.
Through the design of the combined mouth plate, the size of the composite surface of the rubber core and the film can be more conveniently adjusted, the concentration of stress is dispersed, the load-bearing performance and quality of the tires are improved, and the motherboard is prevented from deformation through reinforcement screws.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tire production, and particularly relates to a full-steel rubber core die plate. Background Art
[0002] In all-steel tires, the load-bearing capacity is high, and the design of the sprocket directly affects the load-bearing performance. The shape of the rubber core (especially the shape of the rubber core composite surface) determines the design of the sprocket. Through FEA analysis, the stress concentration point at the sprocket needs to be optimized by adjusting the shape of the hard rubber composite surface to improve performance and improve tire quality. We need to adjust the shape of the rubber core hard rubber composite surface to disperse the stress concentration. If the stress at a certain point is too concentrated, the stress concentration point is prone to early damage during driving.
[0003] The existing pre-mouth shape and mouth shape plate cannot adjust the soft and hard rubber composite surface of the rubber core. Every time the rubber core composite surface is adjusted, the pre-mouth shape plate needs to be redesigned. Utility Model Content

[0005] To this end, the utility model provides a full-steel rubber core mouth plate, including a main board, on which inner card slots and outer card slots of different depths are opened, the inner card slot is matched with an inner embedded plate, and the outer card slot is matched with an outer embedded plate; an extrusion port is arranged on the front side of the main board, a film glue flow channel is opened in the main board, a film glue inlet is opened above the card slot, and a first hard glue flow channel groove is opened at the bottom of the card slot; a first soft glue flow channel groove is opened in the inner embedded plate, and a second hard glue flow channel groove is opened below the first soft glue flow channel groove; a second soft glue flow channel groove is opened in the outer embedded plate, the soft glue inlet is opened above the outer embedded plate, the hard glue inlet is opened below the outer embedded plate, and a third hard glue flow channel groove is opened below the second soft glue flow channel groove.
[0006] Furthermore, the film glue flow channel is only arranged on the main board and is in a Z shape.
[0007] Furthermore, the first soft rubber flow channel groove and the second soft rubber flow channel groove are combined to form a soft rubber flow channel, and the soft rubber flow channel is Z-shaped.
[0008] Furthermore, the first hard rubber flow channel groove, the second hard rubber flow channel groove and the third hard rubber flow channel groove are assembled to form a hard rubber flow channel, and the hard rubber flow channel is a horizontal straight line.
[0009] Furthermore, the soft glue outlet, the film glue outlet and the hard glue outlet together form an extrusion outlet.
[0010] Furthermore, reinforcing screws extending into the interior of the mainboard are arranged on the bottom surface of the mainboard.
[0011] Furthermore, there are three reinforcing screws, which are respectively arranged on both sides and in the middle of the main board.
[0012] The utility model provides a full steel rubber core die plate, which has the following beneficial effects:
[0013] The die plate is designed to be modular and the shapes of different flow channels can be changed by splicing them together, so that the shape of the rubber core extruded from the extrusion port can be more conveniently adjusted so that the composite surface of the rubber core and the film can reach the required size.
[0014] By setting reinforcing screws, multiple positions of the mainboard can be reinforced to prevent the mainboard from being deformed due to excessive extrusion pressure during the extrusion of the rubber core. BRIEF DESCRIPTION OF THE DRAWINGS
