Tonifying Qi inefficiency largely effects on the working efficiency of moulding machine, and at the same time, pressure is uncontrolled in actual operation for it,
The pressure for penetrating sand air accumulator is equal to the pressure of air delivering pipeline connected to it, can reach 0.6~0.8MPa, thus excessively high
Air pressure will lead to moulding machine and penetrate the abrasion of sand system element and accelerate, and be all import spare part due to penetrating sand system element, this
Considerably increase the cost of element replacement.
Summary of the invention
The purpose of this utility model seek to solve it is existing penetrate sand air accumulator tonifying Qi inefficiency, be passed through at work
The problem of air pressure is uncontrolled, penetrates the abrasion of sand system element so as to cause moulding machine and accelerates, and influences moulding machine working efficiency,
A kind of moulding machine is provided thus and penetrates sand making-up air device.
The concrete scheme of the utility model is: a kind of moulding machine penetrates sand making-up air device, includes to be connected to moulding by pipeline A
Machine penetrates sand air accumulator, and the inlet end for penetrating sand air accumulator is connected to air supply tank by pipeline B, and the inlet end of air supply tank passes through appendix
Road connects pneumatics wind system, and solenoid valve is housed on air delivering pipeline, electro connecting pressure gauge is housed on air supply tank；The electric contact pressure
The upper limit contact of table and the coil of an intermediate relay are connected on the DC output end of Switching Power Supply, the direct current output of Switching Power Supply
End is gone back and is connected to the series circuit being made of the normally opened contact of the coil of solenoid valve and intermediate relay, and the exchange of Switching Power Supply is defeated
Enter end and air switch is housed, and is respectively arranged with fuse on every input branch road of air switch.
The air pressure range that sand air accumulator is penetrated described in the utility model is 0~0.8MPa；The electro connecting pressure gauge it is upper
Limit contact is normally-closed contact, and the threshold value which sets is 0.3MPa;The voltage of the exchange input side of the Switching Power Supply
For AC220V, the voltage of DC output side is DC24V.
The utility model structure is simple, ingenious in design, is carried out by the maximum pressure value of electro connecting pressure gauge air supply tank real
When control, meet the shooting pressure requirement of moulding machine, effectively prevent the hypertonia for penetrating sand system, reduce and penetrate sand element
The hidden danger of Rapid Damage due to shooting pressure is excessively high is realized to the quick tonifying Qi of sand air accumulator progress is penetrated, is mentioned significantly at the same time
The high working efficiency of moulding machine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the control circuit schematic diagram of the utility model.
In figure: 1-moulding machine, 2-penetrate sand air accumulator, 3-air supply tanks, 4-pipeline A, 5-pipeline B, 6-air delivering pipelines,

Specific embodiment
Referring to Fig. 1, a kind of moulding machine penetrates sand making-up air device, includes to penetrate sand gas storage by what pipeline A4 was connected to moulding machine 1
Tank 2, the inlet end for penetrating sand air accumulator 2 are connected to air supply tank 3 by pipeline B5, and the inlet end of air supply tank 3 is connected by air delivering pipeline 6
Pneumatics wind system 7 is equipped with solenoid valve 8 on air delivering pipeline 6, electro connecting pressure gauge 9 is housed on air supply tank 3.
Referring to fig. 2, the coil of solenoid valve 8 is expressed as KM1 in Fig. 2, and electro connecting pressure gauge 9 is expressed as YX, electric contact pressure
The upper limit contact of power table YX and the coil KA1 of an intermediate relay are connected on the DC output end of Switching Power Supply UR, wherein the upper limit
Contact is normally-closed contact, and the threshold value that the upper limit contact of electro connecting pressure gauge YX is set is 0.3MPa；The direct current of Switching Power Supply UR is defeated
Outlet also and is connected to the series circuit being made of the normally opened contact KA1-1 of the coil KM1 of solenoid valve and intermediate relay, switch electricity
The ac input end of source UR is equipped with the air switch QS of 2P, and is respectively arranged with fuse on every input branch road of air switch QS
FU1。
The air pressure range that sand air accumulator is penetrated described in the present embodiment is 0~0.8MPa;The exchange of the Switching Power Supply UR is defeated
The voltage for entering side is AC220V, and the voltage of DC output side is DC24V.
The working principle of the utility model is as follows: firstly, air switch QS closes a floodgate, since electro connecting pressure gauge YX is in normality
