With the progress of society, new energy automobiles have a tendency of replacing traditional automobiles, and the new energy automobiles often adopt batteries as power sources, so instrument panels of the new energy automobiles are often prepared by adopting plastic rubber, and in order to ensure the hardness and the strength of the instrument panels, the plastic particles in a molten state need to be subjected to die casting by adopting die casting so as to ensure the strength of the instrument panels of the new energy automobiles.

The clamp is a common auxiliary apparatus for die-casting an instrument panel, is used for preventing the occurrence of scald of technicians, is common knowledge in the field, and is not disclosed too much here.

When the device is used, firstly, the hydraulic telescopic column 8 is controlled to extend, the hydraulic telescopic column 8 drives the upper die 3 to be attached to the lower die 4, the spring 23 can apply elastic force to the lower die 4 through the sliding pressing plate 29 and the rectangular sliding column 10 along with the extension of the hydraulic telescopic column 8, so that the upper die 3 is attached to the lower die 4 more tightly, the phenomenon that slurry overflows due to the fact that the upper die 3 is not attached to the lower die 4 tightly is effectively prevented, the lower die 4 applies pressure to the slurry in a molten state in the chute 21 through the rectangular sliding column 10 and the sliding pressing plate 29, and the slurry for die-casting the instrument panel can generate a tendency of flowing upwards after being extruded.

Along with the extension of the flexible post of hydraulic pressure 8, make the pressure that the ground paste in the silo 21 received continuously increase, the ground paste receives can enter into mould inner chamber 15 through inlet pipe 19 after the pressure, under the pressure that the flexible post of hydraulic pressure 8 provided, the ground paste can pressurize and be full in mould inner chamber 15, make the panel board by die-casting shaping, at the in-process that the flexible post of hydraulic pressure 8 extends, go up mould 3 and can push down mould 4 and drive lower mould 4 and descend, at this in-process, the trend of pushing down through the elasticity of spring 23 and the flexible post of hydraulic pressure 8, and then make and go up mould 3 and lower mould 4 homoenergetic and carry out inseparable laminating, the condition emergence of decline in-process ground paste outflow after preventing to go up mould 3 and the laminating of lower mould 4.

By extending the hydraulic telescopic column 8, the slurry in the trough 21 can be filled in the inner die cavity 15, and the slurry can enter the lower die 4 through the feeding pipe 19 and the one-way valve 28 and then enter the inner die cavity 15. Along with the continuous increase of hydraulic stretching post 8 to last mould 3 applied pressure, the thick liquids that enter into in the mould inner chamber 15 under the pressurization effect of sliding pressure plate 29, the density of thick liquids can continuously increase, on the one hand can effectually prevent to have gap, crackle on the panel board that the die-casting was come out, on the other hand also can avoid appearing the condition emergence of bubble on the panel board, guarantees the die-casting quality of panel board.

After the panel board die-casting, open fan 16 and water pump 25, water pump 25 is after opening, can be through feed liquor pipe 12 towards carrying rivers in the cooling bath 32, and then make rivers cool off the panel board in the mould inner chamber 15 through cooling bath 32, make the panel board design, rivers can enter into connecting pipe 14 after through cooling bath 32, and then enter into silo 21 through connecting pipe 14, this moment rivers can enter into the silo 21 in the cavity that is located the sliding pressure plate 29 top, rivers are after entering into the silo 21 in the cavity that is located the sliding pressure plate 29 top, can exert a decurrent power to sliding pressure plate 29, make the cavity that is located the sliding pressure plate 29 top in the silo 21 reach similar hydraulic pressure's effect, prevent that the sliding pressure plate 29 from upwards the condition of a large amount of gliding from taking place.

When the inside water that is located the cavity of sliding pressure plate 29 top of silo 21 reaches the equilibrium with the elasticity that the ground paste of sliding pressure plate 29 below and spring 23 applyed, the solenoid pressure valve opens, and the water in the silo 21 can get back to in cooling water tank 2 through drain pipe 13, and rivers also can dispel the heat through ventilative mouthful 11 after entering into cooling water tank 2, guarantee cooling water tank 2's cooling quality. The water pump 25 cools the die through water circulation, and in the process, water can be filled in a cavity which is positioned above the sliding pressure plate 29 in the material groove 21, so that the sliding pressure plate 29 is prevented from sliding upwards under the elastic force of the spring 23, the sliding pressure plate 29 is always abutted against the liquid level of the slurry, and air is prevented from being mixed into the slurry to cause air bubbles on a die-cast instrument panel.

In the process that upper die 3 and lower die 4 descend, lower die 4 also can drive piston rod 33 and descend, when piston rod 33 descends, can effectually drive piston plate 34 and descend, and then make the inside air of inflator 5 by effectual compression, when the inside air of inflator 5 is compressed to the inside air pressure of inflator 5 and is higher than the pressure preset value of relief valve 18, relief valve 18 opens, the too big condition of the inside atmospheric pressure of inflator 5 prevents to appear, unnecessary gas sees through relief valve 18 and blows to rectangle traveller 10 simultaneously, can blow away the ash floatage that falls on workbin 7 top, prevent that the ash floatage from piling up in a large number at workbin 7 top. The arrangement of the demoulding assembly can also play a role in promoting the positioning of the lower die 4, so that the lower die 4 is placed in the inclined state, meanwhile, the arrangement of the rectangular sliding column 10 and the sliding pressing plate 29 can also prevent the lower die 4 from being inclined, and the demoulding assembly, the rectangular sliding column 10 and the sliding pressing plate 29 promote each other.

After the mold is cooled, the hydraulic telescopic column 8 is controlled to shrink, and when the hydraulic telescopic column 8 shrinks, the electromagnetic pressure valve and the liquid inlet one-way valve are closed, so that the hydraulic pressure in the cavity above the sliding pressure plate 29 inside the trough 21 is kept stable. The one-way air outlet valve 17 is opened subsequently, so that pressurized air in the inflator 5 can enter the air pipe 26 through the transverse pipe 27, and then the pressurized air is blown to the instrument panel above the one-way valve 28, so that the connection between the instrument panel and the lower die 4 is loose, the purpose of facilitating demolding of the instrument panel after die-casting molding by a technician is achieved, the instrument panel is prevented from being adhered to the inner die cavity 15 of the lower die 4, and the instrument panel can be more easily demolded.

After the 8 shrink of hydraulic stretching post, fan 16 can be towards the direction blast air of upper mold 3 after opening for the peripheral air of upper mold 3 obtains effectual circulation, and after the 8 shrink of hydraulic stretching post, the wind energy that fan 16 blew out can drive the peripheral circulation of air of upper mold 3, and then makes fan 16 cool off upper mold 3, avoids the condition of the 3 high temperatures of upper mold and take place the adhesion when die-casting next time.
