The screw support device of side, this screw support device includes the screw rod, the gear that are arranged within lower die base and is arranged on lower mold base
Cylinder outside Zuo, one end of described screw rod extends in the first groove, and the other end of this screw rod is fixed on the bottom of lower die base,
Described screw rod is welded with gear, and being connected between described cylinder and gear has tooth bar, and described rack and pinion is the most ratcheting.
Described punch outer surface is provided with chiller.
It is provided with heater on the inwall of described first groove.
The two ends of described upper die base are provided with pole, and described lower die base is provided with the second groove matched with pole.
One end of described lower die base is provided with control device, described screw support device, chiller and heater all with
Control device to be connected.
It is provided with temperature inductor inside described upper die base and lower die base.
The beneficial effects of the utility model are:
This utility model arranges screw support device, and this screw support device includes the screw rod, the gear that are arranged within lower die base and sets
Putting the cylinder outside lower die base, one end of described screw rod extends in the first groove, and the other end of this screw rod is fixed on lower mold base
The bottom of seat, described screw rod is welded with gear, and being connected between described cylinder and gear has tooth bar, the mutual tooth of described rack and pinion
Close, during die sinking, promote cylinder band carry-over bar to move by controlling device, rotated by gear driven screw rod, thus realize injection
Part spins off from mould, the demoulding by the way of rotation, makes to exit the moulding stress equalization of molding, at stress equalization
In the case of, the moulding exiting molding is unlikely to deform damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top perspective view of screw support device.
Detailed description of the invention
With embodiment, the technical solution of the utility model is illustrated below in conjunction with the accompanying drawings.
Shown in seeing figures.1.and.2, a kind of Novel injection mold, including upper die base 14 and lower die base 4, described upper mold
Pedestal 14 is provided with annular injection hole 2 and punch 15, and described punch 15 is arranged with injection hole 2 concentric, described injection hole 2
The radius of present position, more than the radius of punch 15, is provided with the first groove matched with punch 15 in described lower die base 4
10 and be arranged on the screw support device below the first groove 10, this screw support device includes being arranged within lower die base 4
Screw rod 8, gear 9 and the cylinder 16 being arranged on outside lower die base 4, one end of described screw rod 8 extends in the first groove 10,
