頼性がない。 2. Description of the Related Art A compressed fluid of 10 kg / cm 2 or more (however, air is 50 kg / cm 2 ) in Japan must be operated according to the High Pressure Gas Control Law. According to this law, a person engaged in the operation of a device for producing compressed gas of 10 kg / cm 2 or more, when the daily production amount becomes 100 Nm 3 or more, is licensed as a chief of species work (high pressure gas production device for one year after passing the test. Therefore, a manufacturing apparatus of a smaller scale is easier for a user to use. However, small capacity, high discharge pressure compressors are commercially designed in the field of motor-driven reciprocating gas compressors, and although they have been developed up to 200 Kg / cm 2, they have a proven record of 24 hours continuous operation and reliability. There is no.

Will be needed. On the other hand, in the booster compressor, the suction pressure is 30 to 50 kg / cm 2 , and two compressors a and b are used to lower the recovery pressure after use (see FIG. 3).

There will be no. Also, since two compressors are required, the production cost will be doubled. On the other hand, since the injection gas pressure differs depending on the shape and thickness of the molded product in the mold,
Conventionally, there is a method of injecting the fluid after adjusting it to a predetermined pressure by installing a pressure adjusting valve immediately before injecting the fluid into the molded product in the mold.

−ルされる。The present invention will be described in detail below with reference to the embodiment shown in FIG. This is an example of boosting from 8.5 kg / cm 2 to 300 Kg / cm 2. The high-pressure suction fluid is supplied to the compressor 3 by the high-pressure suction pressure container 1 through the suction fluid outlet valve 2. At this time, there is no backflow to the low pressure suction pressure vessel 13 due to the check valve 14. The compressed fluid compressed by the compressor 3 up to the injection pressure into the molded product in the mold 7 is accumulated in the compressed fluid container 5 through the check valve 4, and the compressed fluid injection valve 6 is opened to open the compressed fluid. Is injected into the molded product in the mold 7. At this time, the opening and closing time is controlled by the set pressure of the pressure sensor 8 provided in the pressure fluid injection line at the inlet of the mold 7.
The fluid pressure in the molded product is controlled to a predetermined pressure.

The recovery valve 9 is controlled by a pressure sensor or a timer,
Once the equilibrium pressure is reached, the inlet valve of the low pressure suction pressure vessel 13
Open 12 and collect until low pressure inlet pressure vessel 13 reaches equilibrium pressure. Once the equilibrium pressure is reached, the inlet valve 12 of the low pressure suction pressure vessel 13 is closed. At this time, the check valve 11 prevents the high-pressure system fluid in the recovery line from flowing backward.

The atmosphere release valve 10 is closed and the molded product is taken out of the mold 7.
On the other hand, the pressure of the high-pressure suction pressure vessel 1 is set to a predetermined pressure by the sensor 21, and if it is lower than that, the suction fluid outlet valve 2 is closed and the low-pressure suction pressure vessel 13 supplies the low-pressure suction fluid to the compressor 3. The compressor 21 uses the sensor 21 of the high-pressure suction pressure container 13
Compressed to a pressure higher than the set pressure, the high pressure suction pressure supply valve 15 is opened to supply to the high pressure suction pressure vessel 1, and when the set pressure of the sensor 21 is reached, the high pressure suction pressure supply valve 15 is closed and suction is performed again. Open fluid outlet valve 2 and repeat the same cycle. On the other hand, the sensor 22 of the low-pressure suction pressure container 13 is set to the supply pressure to the booster 3, and when the pressure becomes lower than the set pressure, the N 2 supply valve 19 as a fluid opens and the N 2 cylinder 17
The pressure adjusting valve 18 at the outlet automatically supplies N 2 controlled to a predetermined pressure. The amount supplied is equal to the amount of gas released to the atmosphere.

ニングコストの一層の低減を計ることができる。Further, as a method of lowering the atmospheric discharge pressure and effectively using N 2 , as shown in FIG. 2, before the atmospheric discharge valve 10, about 10 times the injected fluid amount of the molded product is used.
23 is provided, and between the atmospheric release valve 10 and the Aki Yum Leta 23,
A bypass circuit 24 is provided and connected to the inlet of the recovery tank 13. A bypass valve 22 is provided in the bypass circuit 24, and after the recovery of the low-pressure recovery line to the recovery tank 13 is completed, the recovery valve 9 and the inlet valve 12 of the low-pressure suction pressure container 13 are closed, and the atmosphere release valve 10 is opened. , Pass the residual gas through the accumulator and apply pressure.
After reducing the pressure to 1/10, the atmospheric release valve 10 was closed and the bypass valve 22
Open and send the hydraulic pressure above the pressure of the low pressure suction pressure container to 10 kg / cm 2 or less (because it does not become a high pressure fluid) from the hydraulic pump 25 to compress the pressure in the accumulator 23, and the pressure switch 26 When the predetermined pressure is reached, the bypass valve 22 is closed. The hydraulic pump 25 is stopped and the oil of the accumulator 23 is dropped into the oil tank to prepare for the next cycle. According to this method, N 2 to be compressed has a pressure of 10 Kg / cm 2 or less, and is not applicable to the high-pressure gas control method. Therefore, it can be manufactured freely and inexpensively, and the recovery rate of N 2 is high. The running cost can be further reduced.
