The working principle and the using process of the invention are as follows: firstly, an operator unscrews the fixing bolts 1303 on the sliding seat 603 and the seal box 606, then takes the clamping vertical rod 1304 off, then puts the mold 14 between the two clamping cross rods 1301, then clamps the clamping vertical rod 1304 into the fixing clamping groove at the bottom of the mold 14, and then screws the fixing bolts 1303 to the inner sides of the corresponding fixing screw holes 1302, so that the mold 14 is fixed, the fixing bolts 1303 and the clamping vertical rods 1304 are fixed at different positions at one end of the clamping cross rods 1301, so that the molds 14 with different specifications can be clamped and fixed, the fixing bolts 1303 are simple and quick, the efficiency of replacing the mold 14 is improved, and the time wasted in replacing the mold 14 is reduced;
after the mold 14 is fixed, an operator presses one end of the lever 1006, the other end of the lever 1006 is lifted upwards under the action of the supporting block 1007, the lifting rod 1002 slides upwards and rises on the inner side of the sliding sleeve 1004, then the lifting rod 1002 drives the top cover 1001 to lift upwards, the top cover 1001 slides out of the inner side of the feeding pipe 9, molten metal to be die-cast is poured into the feeding pipe 9, then the lever 1006 is released, the top cover 1001 falls into the inner side of the feeding pipe 9 newly, the molten metal can be added into the inner side of the storage pipe 804 by pressing the lever 1006 in a hand-foot matching mode, feeding efficiency is improved conveniently and quickly, and the hot feeding pipe 9 can be directly touched by hands by pressing the lever 1006, so that people are prevented from being scalded, and safety of workers is effectively protected;
after the top cover 1001 is dropped, the tightness of the material storage pipe 804 can be ensured, an operator controls the air cylinder 601 to extend towards one side of the fixed seat 5, at the moment, the air cylinder 601 can push the sliding seat 603 to slide towards one side of the fixed seat 5 at the outer side of the sliding guide rod 602, the general mold 14 on the sliding seat 603 and the other half mold 14 in the sealing box 606 can be attached together after moving one end distance, then the sealing box 606 can be inserted into the sealing groove 605 on the inner side of the sealing block 604 at the moment, so that the sealing block 604 and the sealing box 606 can be combined into a whole, at the moment, the air suction pump 611 is opened, when the air suction pump 611 works, air in the sealing box 606 can be discharged to the outer side of the sealing box 606 through the annular air suction pipe 607, the air suction hole 608 and the air exhaust pipe 609, and due to the existence of the one-way valve 610, the air can be prevented from flowing back into the sealing box 606, and the sealing box 606 can be combined into a whole by closing the sealing block 604, because the annular air suction pipes 607 and the air suction holes 608 are uniformly distributed on the inner side of the seal box 606, the exhaust efficiency can be improved, and because the check valves 610 exist, the air can be prevented from flowing back into the seal box 606, the air in the die 14 can be effectively avoided during die casting, sand holes and air holes of a formed die casting piece can be avoided, and the die casting success rate is improved;
then, the horizontal pushing cylinder 801 is controlled to push the pushing rod 802, so that the pushing rod 802 pushes the pressing block 803, then the pressing block 803 quickly pushes the molten metal in the material storage pipe 804, then the molten metal is sprayed to the inner side of the die 14 through the spraying head 805 for forming, when different molten metals are subjected to die casting, the threaded sleeve 809 can be unscrewed, then the horizontal pushing cylinder 801 is controlled to pull the pushing rod 802 back to one side of the horizontal pushing cylinder 801, then the sealing cylinder 806 is pulled out from the inner side of the slot 807, then the pressing block 803 is unscrewed, the pressing block 803 is detached, then the pressing block 803 with a melting point higher than that of the die-cast metal is replaced, the molten metal is prevented from melting with the pressing block 803, so that die casting failure is caused, the pressing block 803 can be replaced after a period of use, the pressing block 803 is prevented from being worn, so that the sealing performance of the inner side of the material storage pipe 804 is reduced, and the threaded sleeve 809 is screwed on the outer side of the material storage pipe 804 again after the pressing block 803 is replaced, therefore, the sealing performance of the storage pipe 804 is guaranteed, the pressure-casting failure caused by the fact that molten metal and the pressure block 803 are melted together can be effectively prevented by replacing the pressure-casting block 803, the pressure-casting success rate is improved, the pressure-casting efficiency is improved, the pressure block 803 can be replaced after being used for a period of time, the sealing performance of the inner side of the storage pipe 804 is prevented from being reduced due to abrasion caused by long-time use of the pressure-casting block 803, and the exhaust of equipment is guaranteed not to be influenced;
finally, after the die casting is formed, an operator controls the cylinder 601 to retract towards one side of the control box 3, then pulls the handle 1205, the sliding cross rod 1204 can slide downwards at the moment, then the spray head 1207 is aligned with the thin-wall part formed by die casting of the cylinder, then an external inflator pump is started to convey gas into the flow dividing pipe 1206 through the air inlet hose 1209, then the gas is divided into the spray head 1207 through the flow dividing pipe 1206, then the gas is uniformly blown to the die casting, the die casting is cooled, cold air is sprayed to the die casting through the spray head 1207 to enable the interior and the surface of the die casting to be rapidly cooled, the danger of scalding when the worker takes the die casting is avoided, the die casting can be completely formed through cooling, the forming efficiency of the die casting is improved, and the working efficiency is further improved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
