Description

The semisolid injection (mo(u)lding) machine of multistation injection
Technical field
It is more particularly to a kind of for the more of magnesium alloy or aluminium alloy the utility model is related to a kind of semisolid injection (mo(u)lding) machine The semisolid injection (mo(u)lding) machine of station injection.
Background technology
Traditional semisolid injection (mo(u)lding) machine has the following disadvantages in terms of article of manufacture:
Firstth, injection volume is little, and traditional semisolid injection (mo(u)lding) machine half only sets a set of injecting unit, and the injection list Member by melting metallic particles barrel heating and helical screw agitator shearing, and passes through spiral shell using the structure of barrel screw rod The push of bar conveys melt to storage cavity, and mould cavity is injected into finally by the injection effect of screw rod;Under normal circumstances so Mechanism injection volume it is fewer than casting die, the reason is that casting die is by the advance melt of smelting furnace, then pour into injection chamber injection progressive die Has die cavity, melt process is separately carried out with injection process, independent mutually, and injection amount is only related with the diameter of injection plunger, therefore can To increase injection amount by increasing injection plunger diameter;In contrast, semisolid process of injection molding is melt process and injection The combination of process mutually restricts, injection volume is improved by increasing diameter and the length of barrel screw rod entirety, will certainly shadow The effect of melt is rung, while will also result in a problem that melt process is slow and injection pressure is insufficient;Furthermore semisolid is injected The barrel and screw rod of forming machine are consumptive material, must be replaced using after a period of time, manufacture its used material as special steel Material, cost is very high, so achieving the purpose that increasing injection volume does not meet economic benefit by increasing barrel screw rod;Semisolid is injected The shortcomings that forming machine injection volume is insufficient determines that it is difficult to produce large-scale thick-walled product, using 650 tons of production of machinery magnesium alloys as Example with the product of the plastic 3.3-5.5kg of casting die, but can only be molded with semisolid injection moulding the product of most 1kg;
Secondth, stream is long than little, and the long ratio of stream refers to that melt flows through in mould cavity path total length and product are averaged Ratio between wall thickness, semi-solid magnesium alloy melt is injected into meeting quick solidification within the extremely short time in mould cavity, special It is not when semisolid melt being injected into the die cavity of thin-gage goods, this requires screw rod to need to provide very high injection pressure (more than 10MPa) and the injection speed (3m/s or so) that is exceedingly fast are to ensure that melt fills up entire die cavity, but if melt is in mould Too long in flow in tool, even if under the injection technique of high-voltage high-speed, melt can also have little time the full entire die cavity of filling will be Cooling solidification is crossed in midway to cause to short and penetrates, by further increase injection pressure and injection speed will certainly to the stability of machine and Service life causes undesirable influence, so existing semisolid injection technique is difficult process flow very long (it is very big to flow long ratio) thin Wall product.
The two exactly above-mentioned shortcomings, constrain the promotion and application of traditional semisolid injection molding technology significantly.
In addition, above-mentioned traditional semisolid injection (mo(u)lding) machine can only prepare oligomict product, but with living standard Raising, oligomict product be difficult meet people variation life the needs of.
Therefore, it is necessary to it is further improved.
