Specifically, in the die casting double-blanking mechanism, as shown in fig. 4 and 5, the first punching assembly 50 includes a punch holder 51 and a punch 52 connected to the punch holder 51; punch retainer 51 is connected to upper plate 20. As shown in fig. 6 and 7, the second punching assembly 60 includes a pressing head fixing base 61 and a pressing head 62 connected to the pressing head fixing base 61; the pressure head holder 61 is connected to the lower plate 30. The number of the first punching assemblies 50 and the second punching assemblies 60 is set according to the actual requirement of the die-cast part to be punched.

In the die casting twice-punching mechanism, a driving device 40 comprises two first oil cylinders 41, a bracket 42, a follow-up plate 43 and a second oil cylinder 44; wherein, two first oil cylinders 41 are fixed on the support 10, and the piston end is connected with the upper plate 20; the bracket 42 is movably arranged on the support 10 and connected with the lower plate 30; the follow-up plate 43 is movably arranged on the bracket 42 and is connected with the upper plate 20; the second cylinder 44 is fixed to the bracket 42, and the piston end is connected to the follower plate 43.

Wherein, the following plate 43 and the upper plate 20, and the bracket 42 and the lower plate 30 are connected by at least two first guide rods 45. The support 10 is provided with a first guide sleeve respectively matched with each first guide rod 45. During operation, under the guiding action of each first guide rod 45, the following plate 43 and the upper plate 20 can be prevented from being shifted when moving relative to the support 10, so that the punching precision of the first punching assembly 50 is prevented from being influenced; likewise, the carrier 42 and lower plate 30 are prevented from shifting when moving relative to the carrier 10 and thereby affecting the cutting accuracy of the second cutting assembly 60.

Further, at least two second guide rods 421 are arranged on the bracket 42; the follower plate 43 is sleeved on each second guide rod 421, and is provided with a second guide sleeve respectively matched with each second guide rod 421.
