Body, and the outside of the gum cover with tooth gum cover 220 221 has biggish pressure, in the case where there is larger pressure on the outside, band tooth glue
The inside flute profile section 222 of set 220 will apply pressure to thick rheid, under the extruding of inside flute profile section 222, flow shape
The transmission belt made-up belt 300 of state is flowed along the marginal portion of cover board medial surface 107 and the intersection of transition joint face 224.Due to
Pressure difference between internal model and vulcanizing tank is larger, and the transmission belt made-up belt 300 of flow regime is possible to covering during extruding
It plate and is flowed；If not using measure, thick transmission belt made-up belt 300 is possible to flow under the action of squeeze pressure
Air inlet 101, or even air inlet 101 is blocked.Since band tooth gum cover 220 is larger to 300 squeeze pressure of transmission belt made-up belt, and into
Stomata 101 is connected with the inside of rigid internal model 210, and pressure herein is relatively small, causes 300 meeting of transmission belt made-up belt of flowing
Flow to the position of air inlet 101.
The cover board week side 106 of the present embodiment with inside smooth section 223 is formed as vertical direction sealing, cover board medial surface
107 edge and transition joint face 224 formation is horizontal direction sealing, so that between on the outside of made-up belt accommodating chamber 250 and cover board
Repeatedly sealing is formed, and the angle between horizontal direction sealing and vertical direction sealing is 90 °, so that sticky transmission belt made-up belt
300 need to overcome the pressure of multiple directions when flowing to 101 direction of air inlet, to avoid the transmission belt band of thick flowing
Base 300 flows to the position of air inlet 101.
At the same time, it is worth noting that the distance between air inlet 101 and cover board medial surface 107 are D1, air inlet 101
The distance between cover board lateral surface 108 is D2, then D1=1.0~1.5D2；That is D1=1.2D2, in exhaust trench 105 and cover board
The distance of side 107 is D3, the distance between exhaust trench 105 and cover board lateral surface 108 are D4, D3=1.2D4.It is worth noting
, the air inlet 101 of the present embodiment is set in exhaust trench 105, and the section of the groove slot bottom 1051 of exhaust trench 105
Product is greater than the sectional area of groove notch 1052；I.e. by being gradually reduced (such as to the opening degree of groove notch 1052, exhaust trench 105
Shown in Fig. 9 and Figure 10), the cross section of the exhaust trench 105 of the present embodiment is swallow-tail form, the groove notch of exhaust trench 105
1052 opening degree is 0.5~20mm, the preferred 2mm of the present embodiment.To increase cover board week side 106 and with tooth gum cover 220
Inside smooth section 223 contact area, to increase the distance and sealing effect of sealing.
Due to groove slot bottom 1051 to groove notch 1052, the opening degree of exhaust trench 105 is gradually reduced；So that groove slot
The opening degree of 1052 positions of mouth is smaller, and so as to avoid at groove notch 1052, band tooth gum cover 220 makes because air pressure is larger
Deformation occurs and generates gap for the position that inside smooth section 223 is contacted with groove notch 1052.This is because, if exhaust trench
105 be flat mouth slot as shown in Fig. 2 groove, since the air pressure in vulcanizing tank is larger, applies pressure to cover board week side 106 in air pressure
When, then it be easy to cause at groove notch 1052, inside smooth section 223 is excessive and sagging because of extruding force, and causes inside smooth
Section 223 generates gap with being squeezed and deformed at 105 groove notch 1052 of exhaust trench, and sealing effect is easily caused to be deteriorated.
