At this time, the lower die 8 is blown to dissipate heat through an external fan and the like until the die-cast automobile part is cooled and formed, the pressurizing cylinder 4 and the electric push rod 23 are started, the air hole 19 is kept closed, the electric push rod 23 drives the push rod telescopic part 24 to be separated from the clamping groove 25, the pressurizing cylinder 4 drives the mounting plate 5 and the upper die 6 to ascend, meanwhile, the mounting plate 5 drives the right rack 11 to ascend, the right rack 11 drives the left rack 13 to descend through the gear 12, the left rack 13 extrudes the sleeve 16 through the piston 17 and gas in the gas channel 18, and the gas pushes the ejector block 21 on the other side to ascend, so that the ejector block 21 ejects the die-cast automobile part.
And because the cooperation of right rack 11 and left rack 13 for the distance that kicking block 21 jack-up equals with the distance that upper mould 6 risen, upper mould 6 is spacing to the top of car spare part, and kicking block 21 rises comparatively slowly, make the car spare part be comparatively soft by ejecting, reduced the damage of direct jacking to the car spare part, improved the effect of jacking, pressurized cylinder 4 continues to rise, when kicking block 21 risees the inside of upper mould 6 completely, air flue 18 is linked together with the outside, can not extrude kicking block 21 any more, at this moment, open gas pocket 19, spring one's 22 elasticity drives kicking block 21 and resets, the die casting operation of next being convenient for.
When the upper dies 6 with different needs are replaced, the limit of the cylinder 33 is released by unscrewing the fixing nut 34, the bolts 28 on the two sides are pulled again, the bolts 28 drive the connecting blocks 31 to move, the connecting blocks 31 squeeze the springs II 32 until the bolts 28 are separated from the inside of the slots 29, so that the limit of the positioning plate 26 is conveniently released, and at the moment, the upper dies 6 can be directly separated from the mounting plate 5.
What is not described in detail in this specification is prior art known to those skilled in the art.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
