The object of the present invention is achieved like this, a kind of cassette rough casting cavity pressure detection means, the pressure inspection
Surveying the opposite face that device is used to detect casting cavity has an opening, and the parallel rough casting die cavity in two open outer end faces is close
Sealing property, the pressure-detecting device include door shape cassette frock, two side and the casting die cavity of the door shape cassette frock
Two openends are corresponding, are provided between the two side of the door shape cassette frock and the openend of casting and are used to seal casting opening
Rubber blanket and the pressing plate for compressing rubber blanket, multiple top pressure pressures are threaded with the two side of the door shape cassette frock
The strong of plate pushes away screw rod, and the inlet and outlet connected with casting die cavity is respectively equipped with the pressing plate, and the import connects with inlet tube
Connect, the outlet is connected through outlet with pressure gauge.
The cassette rough casting cavity pressure detection means of the present invention, during pressure detecting for casting die cavity, die cavity
Two openends are respectively by rubber blanket and pressing plate crush seal, and the thrust of pressing plate is adjusted by pushing away screw rod by force, so as to close
Seal shaggy cavity hatch end face.Then air pressure or hydraulic pressure, and pressurize, observation outlet are filled with into die cavity by inlet tube
The pressurize situation of end pressure table, to judge whether casting die cavity leaks.Therefore the special fitter type of pressure-detecting device of the present invention
Chamber has a symmetrical openings end, and the pressure detecting that the parallel casting in two open outer end faces is begun to speak, detecting tool convenient disassembly, inspection
Survey efficiency high.
As the improvement of the present invention, corresponding to the opening that the inlet and outlet one of is disposed therein on pressing plate or respectively
It is arranged on the pressing plate of both sides.
For ease of improving the intensity of frock, the door shape cassette frock uses flute profile of the steel plate butt welding into opening outwardly.
It is described strong to push away bottom that screw rod is connected with pressing plate provided with T-shaped convex for ease of pushing away the installation of screw rod and pressing plate connection by force
Platform, the pressing plate are provided with the T-slot for being easy to T-shaped boss socket, and the T-shaped boss can rotate in T-slot.
For Optimal improvements door shape tool structure, the side wall of door shape cassette frock corresponding with pushing away screw coaxial by force is provided with peace
Hole is filled, the inner screw sheath with pushing away screw rod cooperation by force is fixed with the mounting hole, the inner screw sheath is close to the direction of pressing plate
The outer step of mounting hole periphery is leaned against provided with card.Set in the present invention in door shape cassette frock screw position corresponding with pushing away screw rod by force
Inner screw sheath, can effective protection door shape cassette frock, can only replacing internal thread when internal thread damages because of frequent uses
Set, without scrapping whole door shape cassette frock, so as to extend its service life.It can in addition contain only intensive treatment internal thread
The mechanical performance of set, to improve the service life of inner screw sheath.
