In cavity center；Cavity bottom is provided with cavity pressure detection module, cavity pressure detection module and pressure display module
Connection；Cavity both sides are both provided with pressure release passage and Pressure channel, and the second automatic cut-off valve is provided on pressure release passage, and supercharging is logical
The first automatic cut-off valve is provided on road；
The Pressure channel is connected with external air source.
Further, which provides the compressed air of 0.5-1MPa for compressed gas source to Pressure channel.
Further, the cavity pressure detection module is using pressure gauge or pressure sensor detection pressure.
Further, the pressure release passage is connected with vacuum pump.By the pumping pressure release of vacuum pump, pressure release can be improved and led to
The pressure release rate in road, quickly to reduce cavity pressure.
Preferably, cavity pressure detection module is provided with multiple, and it is evenly spaced in cavity bottom.Pass through setting
Multiple cavity pressure detection modules, can the more accurate pressure value for comprehensively detecting each position of cavity.
The utility model has the following technical effect that：The cavity pressure detection module set by cavity bottom detects cavity
Pressure, while pressure value is shown by pressure display module, operator changes according to cavity pressure, passes through control first
Corresponding supercharging or the opening and closing of pressure release passage are realized in opening and closing with the second automatic cut-off valve, are pressed with increasing and decreasing cavity, so that cavity
Pressure is in stable state, avoids only with the inaccuracy of artificial micro-judgment cavity pressure variation, is in cavity pressure
In the controlled range of accurate stable, so as to improve the Forming Quality of moulded products.
