Theair channel 44 communicates with theair tube units 8 and is adapted for introducing ambient air into theair tube units 8. - As shown in
Figures 7 and10 , thedispensers 5 are mounted to themain body 4, are adapted for atomizing a working liquid, and are respectively connected to the receivingchambers 421. In this embodiment, each of thedispensers 5 is adapted to introduce and atomize two types of the working liquid, so the atomized working liquid can then be delivered into a respective one of the receivingchambers 421. The two types of the working liquid may respectively be a release agent or water. Each of thedispensers 5 has adispenser body 52, twovalve members 53 and two regulatingmembers 54. - As shown in
Figures 7 ,11 and12 , thedispenser body 52 has a mixingchamber 521, an extendingportion 522, a spreadingportion 523, twofluid passages 524, anair passage 525 and twovalve chambers 527. The mixingchamber 521 is formed in thedispenser body 52 and has aspray opening 526 communicating with the respective one of the receivingchambers 421 for permitting passage of the atomized working liquid therethrough into the respective one of said receivingchambers 421.

Figure 11 , thefluid passages 524 are formed in thedispenser body 52 and are adapted to be respectively connected to two different types of working liquid source for respectively introducing the two types of the working liquid into the mixingchamber 521. One of thefluid passages 524 is formed in the extendingportion 522 and communicates with the mixingchamber 521, so that one of the two types of the working liquid can flow along a first path (I) into the mixingchamber 521. The other one of thefluid passages 524 is formed in thedispenser body 52 and communicates with the mixingchamber 521, so that the other one of the two types of the working liquid can flow along a second path (II) into the mixingchamber 521. Theair passage 525 is formed in thedispenser body 52 and communicates with the mixingchamber 521 at a top end portion of the mixingchamber 521 that is opposite to thespray opening 526, so that high pressure air can pass along a third path (III) into the mixingchamber 521. In this embodiment, the working liquid that flows along the first path (I) is a release agent, and the working liquid that flows along the second path (II) is water. In such manner, the high pressure air that passes along the third path (III) can atomize the two types of the working liquid in the mixingchamber 521, and spray the two types of the working liquid outwardly from thespray opening 526. The ratio of the release agent and the water forming the working liquid may be adjusted as required. - The
valve members 53 are respectively disposed in thevalve chambers 527 of thedispenser body 52. One of thevalve members 53 is operable to open and close a respective one of thefluid passages 524, and the other one of thevalve members 53 is operable to open and close the other one of thefluid passages 524. Each of thevalve members 53 includes atop cover 531 fixedly mounted to a top end of a respective one of thevalve chambers 527 and sealing the respective one of thevalve chambers 527, and amovable bottom valve 532. For each of thevalve members 53, when air flows into a first space defined between thetop cover 531 and thebottom valve 532, thebottom valve 532 would be pushed away from thetop cover 531 to close the respective one of thefluid passages 524, and when air flows into a second space defined between thebottom valve 532 and the respective one of thevalve chambers 527, thebottom valve 532 would be pushed toward thetop cover 531 to open the respective one of thefluid passages 524. It should be noted that, thevalve members 53 may be other conventional valve units in other embodiments. - Each of the regulating
members 54 extends threadedly into thedispenser body 52, and can be rotated to block and unblock a respective one of thefluid passages 524 to control an amount of a respective one of the two types of the working liquid input into the respective one of thefluid passages 524. - As shown in
Figures 6 to 8 , thespray tube units 6 are mounted to themain body 4. In this embodiment, each of thespray tube units 6 includes sevenspray tubes 61 that communicate with a respective one of the receivingchambers 421. Each of thespray tubes 61 has a connectingportion 611 and abent portion 612 bent outwardly. The connectingportion 611 of each of thespray tubes 61 is mounted to a corresponding one of theside boards 412 of themain body 4, and thebent portions 612 of thespray tubes 61 of each of thespray tube units 6 are spaced apart from each other. Thetop seat 41 of themain body 4 further has a plurality ofprotrusions 417 formed in the receivingchambers 421 and corresponding respectively in position to the connectingportions 611 of thespray tubes 61. A height of each of theprotrusions 417 is ranged between 0.3 to 3 millimeters. In this embodiment, the height of each of theprotrusions 417 is 1 millimeter. - As shown in
Figures 8 and9 , the supportingframes 7 extend in the longitudinal direction (L), are disposed under thetop seat 41, are spaced apart from each other in the transverse direction (T), and are disposed for installation of thespray tube units 6 thereto to securely fix thespray tubes 61. - The
air tube units 8 are respectively mounted to two opposite end portions of thebottom seat 43 of themain body 4 in the transverse direction (T), and communicate with theair tank 441. Each of theair tube units 8 includes a plurality ofstraight air tubes 81 mounted to theair tube frame 432, and a plurality ofcurved air tubes 82 mounted to the extendingframe 433. Thestraight air tubes 81 and thecurved air tubes 82 are adapted for jetting out the air which comes from theair channel 44 to thecore plate 241 and thecavity plate 242 once thenozzle mechanism 3 is moved to the location between thecore plate 241 and thecavity plate 242. - As shown in
Figure 4 , thecontrol unit 9 is connected to thedispensers 5 and is adapted for controlling the operation of each of thedispensers 5. In this embodiment, the operation of each of thedispensers 5 is controlled by introducing air into the first and second spaces defined in thevalve chambers 527 to open or close a desired one of the fluid passages 524 (seeFigure 11 ) . Thevalve members 53 are solenoid valves (not shown) . In such manner, a user could set the operating parameters in advance, so that desired ones of thedispensers 5 can be actuated in order, and themould 24 can be consequently sprayed with the water to cool down and then sprayed with the release agent so the user can proceed to the next die casting process. - As shown in
Figures 4 and9 , during operation, when a die casting process is completed, thecore plate 241 and thecavity plate 242 of themould 24 are separated, and a produced blank (not shown) is then removed from themould 24. Next, the drivingarm 23 is driven by thecontrol unit 9 to drive thenozzle mechanism 3 to the place between thecore plate 241 and thecavity plate 242, theair tube units 8 then spray the air to clean burrs clinging to themould 24. Afterward, thespray tube units 6 are adjusted to a place corresponding in position to a certain area of themould 24 which is required to be sprayed with the working liquid, and the working liquid is then introduced into a respective one of thedispensers 5 to be atomized. Then, the water is sprayed out to cool down themould 24, and a release agent liquid (a mixture of the water and the release agent) is then sprayed onto themould 24. Finally, theair tube units 8 are driven to blow the air to cool down the release agent liquid for the next die casting process. - If the
mould 24 size needs to be changed, the user only needs to adjust the position of thenozzle mechanism 3, so that replacement of theentire nozzle mechanism 3 is not required. - It should be noted that, each of the
dispensers 5 may be configured to atomize and spray out only one type of the working liquid. Since the receivingchambers 421 are isolated, some of thedispensers 5 can be connected to a water source and actuated first, and the remaining of thedispensers 5 can be connected to a release agent source and actuated later. In such manner, the same effectiveness of the die casting process can be achieved. - With the abovementioned configuration, the die casting machine of the disclosure has the following advantages:
- 1. The
nozzle mechanism 3 can be adjusted for various working areas of moulds with different sizes, and the replacement thereof is not required, so high costs associated with die casting process can be avoided. - 2. With the spaced-apart
bent portions 612 of thespray tube units 6, the working liquid can be evenly sprayed out, and a spraying efficiency is increased. - 3. Since different types of the working liquid can be selected to be sprayed out from the
nozzle mechanism 3, time for themould 24 to cool down and the amount of release agent used can be reduced. - 4. The same effectiveness of the die casting process can be assured when each of the
dispensers 5 only atomizes and sprays out one type of the working liquid. - 5. The atomized working liquid can be well-mixed after hitting the spreading
portions 523 of thedispensers 5 and being received in the receivingchambers 421. - 6. The
turbulence plates 415 can allow the atomized working liquid that is received in the receivingchambers 421 to be further mixed. In addition, theturbulence plates 415 can allow the atomized working liquid to be evenly received in the receivingchambers 421, so that thespray tubes 61 may have equal flow rates. - 7. With the design of the
protrusions 417, turbulent flows may be created in the receivingchambers 421 near thespray tubes 61. In such manner, the atomized working liquid can be further mixed. - 8. The
nozzle mechanism 3 can be moved by the drivingarm 23 relative to themould 24 to thoroughly clean themould 24. - 9. By virtue of the
straight air tubes 81 and thecurved air tubes 82, theair tube unit 8 can spray in different angles, thereby increasing the burr-cleaning efficiency. - In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to "one embodiment," "an embodiment," an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects.
