1, jet pipe of the present utility model by the compressed air high velocity jet of air compressor in vacuum generator, nozzle exit in vacuum generator inside forms jet and produces and entrainment flowing, under Involving velocity, make the air at gas-tpe fitting place, nozzle exit lower end constantly be sucked away, vacuum generator internal pressure is made to be down to below atmospheric pressure and to form vacuum, and then air is constantly pumped to vacuum generator inside and forms vacuum in the matched moulds die cavity that connected by gas-tpe fitting of Involving velocity, thus avoid air blow back and the excessive phenomenon of suction, improve formed product effect, vacuum generator right-hand member muffler can by from noise during matched moulds die cavity extracting air and entrainment flowing formed vacuum process time noise reduction.
2, air compressor of the present utility model is Axial Flow Compressor, the unit are gas through-flow ability of Axial Flow Compressor is large, good operation stability, so Axial Flow Compressor by wireway to start rapidly during air inlet in jet pipe and air-flow is large, ensure the stable supply of the Compressed Gas of jet pipe high velocity jet.
3, magnetic valve of the present utility model is direct-acting electromagnetic valve, during direct-acting electromagnetic valve energising, solenoid produces electromagnetic force by valve open, during power-off, electromagnetic force disappears then valve closing, direct-acting electromagnetic valve starts and closedown is easy to control, and the compressed air that effectively can improve air compressor enters the intake efficiency of vacuum generator.
4, jet pipe of the present utility model is adjustable jet pipe, adjustable jet pipe can change compressed air dynamics and flow by adjustable jet tube area ratio, air in matched moulds die cavity can absorb by power of entrainmenting that compressed air is formed by nozzle exit just completely, can not cause that the power of entrainmenting is excessive affects formed product effect.
5, mould inside exhaust passage of the present utility model number is five, experimental result shows, when five exhaust passages can avoid exhaust passage very few, in vacuum generator suction matched moulds die cavity, the dynamics of air is excessive affects injection molding finished product molding effect, and when exhaust passage can be avoided again too much, swabbing action too much affects injection molding finished product forming shape simultaneously.
6, muffler of the present utility model is resistive muffler, vacuum generator internal nozzle outlet compressed air entrainments and the noise formed in vacuum environment process is high-frequency noises, the sound-absorbing porous material of resistive muffler inside is good to medium-high frequency soundproof effect, can effectively reduce vacuum generator inside formed vacuum time noise.
