Domain can not meet to require.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of semi-solid magnesium alloy pressure charging system, can be solid half
After the injection of state magnesium alloy terminates, in the product solidification shrinkage stage, apply an extra pressure on product rapidly, play metal
The effect of feeding is solidified, improves forming quality of products, meets automobile and the requirement of communication field product quality.
The utility model in order to solve its technical problem used by technical scheme be：A kind of semi-solid magnesium alloy supercharging system
System, including screw rod and injection cylinder, injection ram, the injection ram of the injection ram is provided with the oil pocket of the injection cylinder
Bar is stretched out from the front end of the injection cylinder, and the screw rod is fixedly connected with the injecting piston rod, the oil of the injection cylinder
Chamber can drive the injection ram motion to drive the screw rod to move forward and backward when entering fuel-displaced, outside the rear end of the injection cylinder
Provided with pressurizing cylinder, the supercharging piston rod of the pressurizing cylinder is stretched into the oil pocket of the injection cylinder；The pressurizing cylinder
Booster-type accumulator is provided with above rear end, is provided with hydraulic fluid chamber in the booster-type accumulator, the hydraulic fluid chamber passes through hydraulic pipeline
It is communicated in the oil pocket of the pressurizing cylinder.
As further improvement of the utility model, the pressure pipeline is provided with supercharger control valve.
As further improvement of the utility model, the booster-type accumulator is fixed on the rear upper side of the hydraulic jack
On face, the pressure pipeline passes through from the bottom of the hydraulic jack, and the pressure pipeline is first vertically arranged the company of being horizontally disposed with again
Pass in the oil pocket of the pressurizing cylinder.
As further improvement of the utility model, the horizontal segment of the pressure pipeline is located at the center of the pressurizing cylinder
On axis.
The beneficial effects of the utility model are：The semi-solid magnesium alloy pressure charging system after injection cylinder by setting up supercharging
The pressure charging system that oil cylinder and booster-type accumulator are formed, it is fast in the product solidification shrinkage stage after terminating semi-solid magnesium alloy injection
Speed applies an extra pressure on product, to play a part of metal freezing feeding, so that in the product produced
Dense structure of portion, intensity are high, and because employing the technique of semisolid, material internal is spheroidal cementite, than other Foundry Productions
Magnesium alloy dendrite have higher intensity and elongation percentage, the requirement of automobile and communication field can be met completely.

Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But guarantor of the present utility model
Shield scope is not limited to following embodiments, i.e., is made in every case with present utility model application the scope of the claims and description simple
Equivalent changes and modifications, all still belong within the utility model patent covering scope.
It is a kind of semi-solid magnesium alloy pressure charging system described in the utility model refering to Fig. 1, including screw rod 1 and injection oil
Cylinder 2, is provided with injection ram 21 in the oil pocket of the injection cylinder, and the injecting piston rod 22 of the injection ram is from the injection oil
The front end of cylinder is stretched out, and the screw rod is fixedly connected with the injecting piston rod, and the oil pocket of the injection cylinder can when entering fuel-displaced
Driving the injection ram motion, the rear end of the injection cylinder is externally provided with pressurizing cylinder 3 to drive the screw rod to move forward and backward,
