DETAILED DESCRIPTION
[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.
[0018] like Figure 1As shown in FIG. 2 , the utility model provides a PCR pre-mouth plate using a TBR shoulder pad line, comprising a main board 1, wherein a crown rubber flow channel 5, a base rubber flow channel 6 and two wing rubber flow channels 7 are provided inside the main board 1. The base rubber inlet 3 is arranged in the middle of the back of the main board 1, and the crown rubber outlet 8 is arranged in the middle of the front of the main board 1; the base rubber outlet 9 is arranged directly below the crown rubber outlet 8, and the crown rubber inlet 2 is arranged directly above the base rubber inlet 3. The two wing rubber inlets 4 are respectively located at the lower left corner and the lower right corner of the back of the main board 1, and the two wing rubber outlets 10 are respectively located at the upper left corner and the upper right corner of the crown rubber outlet 8 on the front of the main board 1.
[0019] like Figure 3-5 As shown, the height of the crown rubber inlet 2 is 25 mm, and the width is 320 mm, the height of the crown rubber outlet 8 is 20 mm, and the width is 300 mm; the height of the base rubber inlet 3 is 15 mm, and the width is 340 mm, the height of the base rubber outlet 9 is 10 mm, and the width is 320 mm; the height of the tire wing rubber inlet 4 is 20 mm, and the width is 100 mm, the height of the tire wing rubber outlet 10 is 12 mm, and the width is 130 mm.
[0020] like Figure 2 As shown, on the back of the main board 1, the side edge of the crown rubber inlet 2 is 160 mm away from the vertical center line of the main board 1, and the top edge is 75 mm away from the horizontal center line of the main board 1; the side edge of the base rubber inlet 3 is 170 mm away from the vertical center line of the main board 1, and the top edge is 5 mm away from the horizontal center line of the main board 1; the inner side edge of the tire wing rubber inlet 4 is 180 mm away from the vertical center line of the main board 1, and the bottom edge is 60 mm away from the horizontal center line of the main board 1.
[0021] like Figure 1 As shown, on the front side of the main board 1, the side edge of the crown rubber outlet 8 is 150 mm away from the vertical center line of the main board 1, and the bottom edge is 10 mm away from the horizontal center line of the main board 1; the side edge of the base rubber outlet 9 is 160 mm away from the vertical center line of the main board 1, and the top edge is 14 mm away from the horizontal center line of the main board 1; the side edge of the tire wing rubber outlet 10 is 105 mm away from the vertical center line of the main board 1, and the bottom edge is 18 mm away from the horizontal center line of the main board 1.
[0022] Through the pre-mouth plate with the above-mentioned size setting, PCR tread can be produced on the TBR shoulder pad line, and the tread products of the two types of production lines can be flexibly adjusted to better meet production needs.
[0023] like Figure 1As shown, the outer sides of the two tire wing rubber outlets 10 are additionally provided with ribs 11, and the length of the ribs 11 is 70 mm. The reason for adding ribs 11 is that the tire wing rubber flow channel 7 needs to enter from the bottom of the main board 1 and be extruded from the top of the main board 1. In order to prevent the direction of the tire wing rubber flow channel 7 from interfering with the directions of the crown rubber flow channel 5 and the base rubber flow channel 6, the overall direction of the tire wing rubber flow channel 7 expands outward along the left and right sides of the main board 1. However, since the continuity needs to be ensured during the flow channel design, it is impossible to design a curved flow channel. Therefore, after the tire wing rubber flow channel 7 expands outward, the width of the tire wing rubber outlet 10 is too long to meet the PCR tread requirements. By adding ribs 11 of specific sizes, the extruded tire wing rubber can meet the product requirements again.
[0024] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0025] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
