Second half side view of intracardiac tire is adapted, and sets upper inflation inlet from outside to inside in the outside of upper mould.
As a further improvement, described upper inflation inlet is radially arranged, and also set up from outside to inside on the outside of upper mould
Upper exhaust outlet, upper exhaust outlet is with upper inflation inlet in 45 ° of settings.
As a further improvement, the die cavity outer end both sides of described lower mould are respectively arranged with enlarging inclined-plane.
As a further improvement, the medial surface both sides of the medial surface of described lower mould and upper mould are respectively arranged with inclined-plane.
In order to realize second above-mentioned purpose, present invention employs following technical scheme：
A kind of method for preparing fretting map polyurethane solid inner tube, the method is using the mould described in above-mentioned any one technical scheme
Tool device, the method comprises the following steps：
1）Die device sprays interleaving agent and is preheated to 70 ~ 100 DEG C in advance；
2）By foamed thermoplastic polyurethane (E-TPU) foamed material, according to inner tube of a tyre specification difference, it is packed into according to different quantifying
Die device；
3）Vulcanization board matched moulds switch is opened, when matched moulds to die device upper die and lower die just contacts to form closing space, temporarily
Stop mould assembling action, upper die and lower die are passed through 0.2 ~ 0.8MPa steam 10 ~ 30 seconds step by step；
4）To complete matched moulds in place, upper die and lower die continue to be passed through steam, 10 ~ 30 seconds duration continuation matched moulds；
5）Upper die and lower die matched moulds, 10 ~ 30 seconds pressurize duration；
6）Terminate die sinking, take out inner tube finished product, the finished product inner tube of a tyre is tested, deburring treatment.
Preferably, the foaming thermoplastic that described foamed thermoplastic polyurethane is gone out using BASF Aktiengesellschaft's recent development
Property polyurethane (E-TPU) Infinergy foamed materials.
The present invention proposes a kind of new lightweight, long service life, the fretting map solid inner tube production technology of environmental protection, leads to
Cross and find and apply new material, the inner tube of a tyre and related cover tire, the reasonable structure design product structure of wheel rim are analyzed, while newly developed
Production mould and manufacturing process, equipment, have produced this product.The Product Assembly is encountered to after use on bicycle
After glass dregs, iron nail or complex road condition poke cover tire and this product, will not the gas leakage as traditional inflatable inner tube it is deflated, remain to
Normally ride.And this product does not have laborious, the situation that service life is short occurred in the use of former solid tyre in.Through
Cross the physical and chemical performance to test specimen, air-tightness and endurance quality etc. to test, comply fully with national standard and such is produced
The requirement of product.The product have the advantages that maintenance less, lightweight, long service life, with part substitute conventional tires potentiality.
