Below with reference to Fig. 1-Figure 11, to being described in detail according to the course of work of the apparatus of metal molding 1000 of the utility model specific embodiment, wherein apparatus of metal molding 1000 also comprises the vacuum detecting system for detection of vacuum.
First, after start, control system 6 is carried out self check, whether normally detect cooling water pressure, each valve position in atmospheric pressure, the Water-cooling circulating supply system 4 in working chamber 501 simultaneously, as crucible 502 just arranged without extremely smelting apparatus 5 being carried out to initial reset to feeding port 508, enter into normal operating condition, as occur extremely carrying out sound and light alarm, and wrong information is presented in the man-machine interface of control system 6.
Pay-off 12 is sent to raw material in the crucible 502 in working chamber 501 by feeding port 508, then vacuum extractor 3 vacuumizes working chamber 501, die device 10, injection device 8, when pressure in vacuum detection system detects working chamber 501, die device 10, injection device 8 reaches requirements, heating unit 003 start to the raw material in crucible 502 heat take by raw material melting as molten condition, and die device 10 closes film and is warming up to and needs temperature.
In the process of melting, video image in CCD system 9 Real-time Collection smelting apparatus 5, operating personnel can observe the situation in smelting apparatus 5 by the display screen of CCD system 9, can rule of thumb judge smelting temperature by video, infrared temperature sensor detects smelting temperature, is presented in real time in man-machine interface.Control system 6 is controlled heating power supply power according to the default heating current of technique and heat time, and realizes heating, the control of insulation multistage, accurate temperature controlling.
After adding hot smelting and completing, servomotor drives water cooled electrode assembly 504 and crucible 502 to rotate, the raw material of molten condition is poured in barrel assembly 81, crucible 502 suitably stops with assurance raw material and all pours in barrel assembly 81, then crucible 502 turns back at a high speed cool position, pass into inert gas and crucible 502 is carried out cooling, guarantee that crucible 502 temperature are reduced to not oxidizable temperature before die sinking.
Last operation personnel clear up mould, barrel, tup etc., and operating personnel open feeding port 508, and next recycle feed is poured into from feeding port 508, carry out next one circulation.
Aspect design parameter, the apparatus of metal molding 1000 of the utility model embodiment can drop to the vacuum of smelting apparatus 5 and injection device 8 within the scope of 5～200Pa in 2～20 seconds, limiting value can reach in 10Pa, and voltage rise is not more than 0.5Pa/ second, just can fully provide at short notice excellent vacuum environment.The product of vacuum being had relatively high expectations for non-crystaline amorphous metal etc., apparatus of metal molding of the present utility model can drop to the vacuum of smelting apparatus 5 and injection device 8 below 100Pa in 15 seconds.Design parameter can be set on equipment, can make real-time modification according to the technological requirement of producing product.
