Description
Technical field
The present invention relates to it is a kind of it is novel, for carrying out vacuumizing and exhausting processing to die casting in die-cast production
Mold vacuum evacuation device and accordingly vacuumize operation technique.
Background technique
During die-cast, if the air in die casting is not excluded completely, produced by die-cast
The die-cast product of acquisition is just also easy to produce the defects of stomata, cold shut.Therefore, die-cast mold vacuum evacuation device just becomes die casting casting
An important production ancillary equipment device of production is made, the main function of this important production ancillary equipment device is exactly will
Gas in the mold of die-cast vacuumize draining by corresponding die-cast mold vaccum-pumping equipment, to make to press
The defects of casting casting manipulations can be good at completing, and then the product for avoiding passing through die-cast acquisition generates stomata, cold shut.But
There is bulky, noise big, not energy-efficient etc. defect when work in die-cast vaccum-pumping equipment now used.Therefore,
How to reduce the volume of die-cast vaccum-pumping equipment, and can reduce simultaneously die-cast vaccum-pumping equipment work when noise and
Energy consumption is exactly a die-cast technical field project urgently to be resolved at present.
Summary of the invention
First main inventive purpose of the invention, be to provide a kind of overall volume is small, die casting easy to use take out it is true
Empty device；Second main inventive purpose of the invention, is to provide a kind of pair of die casting vacuum evacuation device and carries out vacuumizing operation
Technique.
Technical solution used in mold vacuum evacuation device is：A kind of mold vacuum evacuation device, including rack, rack include machine
