Description
Technical field
The present invention relates to a kind of vacuum extractor, more particularly, to a kind of vacuum means of injecting type vulcanization of rubber mould
Put.
Background technology
At present, injecting type vulcanization of rubber mould generally includes the upper die plate being arranged above and below and lower template, upper die plate and lower mould
Multiple vulcanization passages and multiple die cavities are respectively arranged with plate, are interconnected between multiple vulcanization passage and multiple die cavities.Rubber
Sulfuration process needs to carry out under vacuum, thus, needs to carry out vacuumize process to vulcanization of rubber mould in vulcanization.
Existing vacuum extractor mainly includes evacuator, is grown by opening up out shallow in the die joint of each die cavity
Air flue, then air flue latter end is connected with evacuator, evacuator by the air in die cavity by air flue extract out.It is existing
There is problems with vacuum extractor：When the first, being vacuumized before injection fillers, due to connecting the gas of each die cavity on die joint
Road is shallow and grow, vulcanization part end face need sealing cause to cause to have no time to spare gas or the vacuum taken out it is inadequate；Injecting
Injected in journey while vacuumize, due to charging filling successively (different according to part damping capacity structure) have it is uncertain
Property, easily cause air flue and block and reduce the effect that vacuumizes or can not vacuumize；Thus either still exist before the injection
In injection, its vacuumizing effect is poor, easily causes the rotten bubble of vulcanization part and scarce degumming phenomenon and scraps；2nd, in air flue
Vulcanized rubber can form the slitter edge of vulcanization part, after the completion of part vulcanization, be also additionally required and cut off the slitter edge for vulcanizing part,
On the one hand the significant wastage of the means of production is caused, the reduction of production efficiency is on the other hand caused.
The content of the invention
It is good that the technical problems to be solved by the invention are to provide a kind of vacuumizing effect, and it is useless to produce vulcanization part
