1. Technical Field
The present disclosure relates to a pressure controlling system and a pressure controlling method.
2. Description of Related Art
A gate is located on an end of a part made by injection molding. When injection molding of the part is completed, it is necessary to break the gate off from the part. However, the gate often has a large size and a lot of time may be required to remove and trim the gate off the part. Thus, removal of the gate may cause the injection molding process to be less efficient. Therefore, an improved system and method may be desired within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

The filtrating valve 61 is used to filter out impurities passing through the connecting pipe 70. The pressure adjusting valve 63 is used to adjust the second pressure value, and a pressure adjusting meter 631 and a switch 633 are connected to the pressure adjusting valve 63. The pressure adjusting meter 631 is used to display the pressure value, which can be adjusted by the pressure adjusting valve 63. The switch 633 is used to open or close the pressure adjusting valve 63. The inverse proportion valve 64 is used to adjust the second pressure value, which is applied to the pressurized device 40. In one embodiment, an inverse proportion meter 641 is connected to the inverse proportion valve 64, and a range of the second pressure value is 10 kg/cm2. The electrically operated routing valve 65 is used to adjust a flow direction of the gas in the pressurized device 40. In one embodiment, the first and the second gas transmitting pipes 66, 67 are located on first side of the electrically operated routing valve 65, and the connecting pipe 70 is located on a second side of the electrically operated routing valve 65.
A noise elimination pipe 68 is connected to the electrically operated routing valve 65. In one embodiment, the electrically operated routing valve 65 is a standard routing device that is used in the industry whereby one or more outlets or inlets (holes) can be opened/connected or closed/disconnected by one or more moving magnetically-responsive barrier(s) which are governed by electromagnetism. Each one of four holes in the electrically operated routing valve 65 communicates with different pipes. For example, the four holes communicate with the first gas transmitting pipe 66, the second gas transmitting pipe 67, the connecting pipe 70 and the noise elimination pipe 68, respectively. A valve(not shown) is located in the shielding cavity, and two electronic magnets(not shown) are received in the shielding cavity. One of the two electronic magnets is electrified, and the barrier can be pointed at the one of the two electronic magnets or moved towards it. Therefore, the hole can be covered by the reorientation or moving of the barrier. For example, the connecting pipe 70 and the first gas transmitting pipe 66 can be opened, or the connecting pipe and the second gas transmitting pipe 67 can be opened, or the first gas transmitting pipe 66 and the noise elimination pipe 68 can be opened, or the second gas transmitting pipe 67 and the noise elimination pipe 68 can be opened.
The pressurized device 40 includes a moving cavity 41, a receiving cavity 43, and a connecting base 45 connected to the moving cavity 41 and the receiving cavity 43. In one embodiment, the pressurized device 40 is received in the interior of the power supply cabinet 10 in a direction substantially parallel to the door 11. The moving cavity 41 includes a piston device 411 and a plurality of strengthening posts 413. The piston device 411 includes a first piston 4110, a second piston 4112, and a connecting portion 4114 connected to the first piston 4110 and the second piston 4112. The first piston 4110 is located in the moving cavity 41, and the second piston 4112 is located in the receiving cavity 43. In one embodiment, a diameter of the first piston 4110 is greater than that of the second piston 4112. The first gas transmitting pipe 66 is above the first piston 4110, and the second gas transmitting pipe 67 is under the first piston 4110.
The receiving cavity 43 is used to receive liquid and a pipe 42 is connected to the bottom of the receiving cavity 43. In one embodiment, the liquid can be oil, which is subject to an original pressure value that is less than the second pressure value. A meter 421, an inducing machine 423 and a direction transferring valve 425 are connected o the pipe 42. The meter 421 is used to display the pressure value in the pipe 42. The inducting machine 423 is used to induce the pressure value in the pipe 42. The direction transferring valve 425 is used to transfer the direction that the oil out of the pipe 42. In one embodiment, the moving cavity 41 and the receiving cavity 43 are cylinders, and a diameter of the moving cavity 41 is greater than that of the receiving cavity 43. A cross-section of the connecting base 45 is a rectangle, and a length of the connecting base 45 is greater than the diameter of the moving cavity 41.

When a gate of the plastic member needs to be cut, the electrically operated routing valve 65 is opened to communicate the connecting pipe 70 with the first gas transmitting pipe 66. The gas with the second pressure value can be transmitted to the moving cavity 41 and bear on the first piston 4110, via the first gas transmitting pipe 66. At this time, the gas with the second pressure value is greater than the original pressure value in the moving cavity 41. Thus, the piston device 411 is moved downward to move the liquid out of the receiving cavity 43 to the hydraulic cylinder plate 80 via the pipe 42. Simultaneously, the electrically operated routing valve 65 is opened to communicate the second gas transmitting pipe 67 with the noise elimination pipe 68. The gas can be move out of the receiving cavity 43 from the second gas transmitting pipe 67 with the noise elimination pipe 68. Therefore, a gas with a third pressure value is located in the moving cavity 41, and the third pressure value is less than the second pressure value. The liquid, that is transmitted to the hydraulic cylinder plate 80, is divided between the four of the sub-pipes 90. Therefore, the gas can be transmitted to the hydraulic cylinder 1011 via the sub-pipes 90. The hydraulic cylinder 1011 moves the cutter 1013 to cut the gate of the plastic member.
After the gate of the plastic member has been cut, the electrically operated routing valve 65 is opened to communicate the connecting pipe 70 with the second gas transmitting pipe 67. The gas with the second pressure value is transmitted to the receiving cavity 43. The gas with the second pressure value is greater than that the gas with the third pressure value, and the piston device 411 is moved upward. Therefore, the liquid is moved back to the receiving cavity 43 via the sub-pipes 90, the hydraulic cylinder plate 80, and the pipe 42 in turn. Simultaneously, the electrically operated routing valve 65 is opened to communicate the first gas transmitting pipe 66 with the noise elimination pipe 68, and the gas moves out of the moving cavity 41 via the first gas transmitting pipe 66 and the noise elimination pipe 68. Then the piston device 411 ceases working, to await a subsequent process.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
