Specific embodiment:

Below be based on the embodiment of embodiment 1-embodiment 4 explanation casting devices of the present invention shown in the drawings and casting method.

Embodiment 1:

At first, description architecture.

Fig. 1 is the structural representation of the casting device of embodiment 1.

As shown in Figure 1, the casting device of embodiment 1 is that alloy melting liquid horizontal direction is compressed into the die casting machine that mold cavity is cast, and has mould 1 and 2, mould 3 and 4, die casting tube 12, running channel 8, vibrating member 10 and ultrasonic wave and takes place and control device 11.

Liquation inlet 5 is arranged on the die casting tube 12, and the exert pressure running channel 8 of flowing through of the alloy liquation that pours into from liquation inlet 5 gets into mold cavities, accomplishes injection process.Die casting tube 12 is connected with running channel 8, and running channel 8 is fixed on the fixed die 3, and running channel 8 is identical with the internal diameter of die casting tube 12, and the plunger 6 of slip is arranged in the die casting tube 12, and the plunger rod 7 that connects power facility is arranged on the plunger 6.

But mould has fixed die 3 and dynamic model 4, but fixed die 3 and dynamic model 4 form mold cavity 9 and cast gate when closed, and cast gate communicates with running channel 8.Fixed die 3 is fixed on the fixed disk 1, but dynamic model 4 be fixed on can with respect to fixed disk 1 do away from or approaching movable plate 2 on, with movable plate 2 motions.The through hole that inserts die casting tube 12 is arranged on the fixed disk, the through hole that holds running channel 8 is arranged on the fixed die.

But all be provided with vibrating member 10 in fixed die 3 and the dynamic model 4, vibrating member 10 all is embedded in the mould, all less than linking to each other with mold cavity 9.

Ultrasonic wave takes place and control device 11 links to each other with running channel 8 with vibrating member 10.Running channel directly imposes ultrasonic vibration to liquation when liquation injects, but the ultrasonic vibration of the fixed die 3 and the vibrating member 10 of dynamic model 4 inside passes to mould, indirectly the liquations in the mold cavity 9 is imposed ultrasonic vibration by mould.

Casting method in the face of embodiment 1 describes down.

In the casting method of embodiment 1, but dynamic model 4 is approaching with fixed die 3, forms mold cavity 9 and cast gate; Plunger 6 is rested in die casting tube 12 tops; The liquation inlet 5 of ready alloy liquation from die casting tube 12 poured in the die casting tube 12, and this gets into the injection process in the die casting tube 12 for liquation, starts dynamical system and promotes plunger rod 7; Actuation plunger 6 is packed into liquation promote to flow through die casting tube 12, running channel 8 in the mold cavity 9, and this is an injection process.

On the other hand; When injecting, liquation opens running channel 8 ultrasonic vibrations when die casting tube 12 is flowed through running channel 8; Liquation in running channel 8 and the die casting tube 12 applies ultrasonic vibration, opens the ultrasonic vibration of vibrating member 10 subsequently, through mould the liquation that gets in the mold cavity 9 is applied ultrasonic vibration; When instrument demonstration melt temperature is lower than the freezing point of alloy, close the ultrasonic vibration of running channel 8 and vibrating member 10, get cast product but move the dynamic model mould unloading.

The casting method of embodiment 1 has realized that marginal not is gone into the limit vibration, marginal not is penetrated the limit and vibrated, just solidifies the limit vibration; The former is the single ultrasonic vibration of running channel 8; Both are stacks of the ultrasonic vibration of running channel 8 and vibrating member 10 for the backs, are packed into liquations in the mold cavity 9 and are the equal of at vibrating member 10 and running channel 8 to solidify and obtain cast product indirectly with under the direct dual ultrasonic vibration.

Following description effect.

In the casting device and casting method of embodiment 1, can obtain following effect.

(1) a kind of casting device; The alloy liquation is injected die casting tube 12, with mold cavity 9 injections of alloy liquation behind matched moulds, make cast product then; One running channel 8 wherein is set to link to each other with mold cavity 9; Running channel 8 opposite sides link to each other with die casting tube 12 and communicate, and some vibrating members 10 are set in the mould, and running channel 8 and vibrating member 10 take place with ultrasonic wave and control device 11 is connected and carry out ultrasonic vibration.

Therefore; When alloy is injected die casting tube 12 and alloy is injected into mold cavity 9 and solidified cast cast product; Because injecting, liquation opens running channel 8 ultrasonic vibrations when die casting tube 12 is flowed through running channel 8; Liquation in running channel 8 and the die casting tube 12 applies ultrasonic vibration, opens the ultrasonic vibration of vibrating member 10 subsequently, through mould the liquation that gets in the mold cavity 9 is applied ultrasonic vibration; Realized that marginal not is gone into the limit vibration, marginal not is penetrated the limit and vibrated, just solidifies the limit vibration; The former is the single ultrasonic vibration of running channel 8, and both are stacks of the ultrasonic vibration of running channel 8 and vibrating member 10 for the backs, is packed into liquations in the mold cavity 9 and is the equal of at vibrating member 10 and running channel 8 to solidify and obtain cast product indirectly with under the direct dual ultrasonic vibration; So such structure can apply longer time, ultrasonic vibration more efficiently to liquation, obtains the cast product of better quality.

(2) above-mentioned vibrating member 10 is separate.

Therefore, separate vibrating member 10 in the mould can selectively impose the ultrasonic vibration of varying strength to the foundry goods different parts, thereby improves the quality of foundry goods, and a plurality of relatively independent vibrating members 10 effect for producing heavy castings is especially outstanding.

(3) above-mentioned running channel 8 is ceramic.

Therefore, the running channel of ceramic 8 can be high temperature resistant, and intensity is good than mold materials, and running channel 8 is imposed high-intensity ultrasonic vibration and do not cave in, and do not fall slag, guarantees better vibrating effect and product quality.

(4) above-mentioned running channel 8 is arranged on the position that casting strength is had relatively high expectations.

Therefore; On the basis of above-mentioned (1)-(3) record effect; Because the ultrasonic vibration that running channel 8 produces acts on from the nearest position of running channel 8 at first, and running channel 8 injects beginning from liquation and all is in the ultrasonic vibration state to solidifying, so the dendrite fragmentation of the foundry goods part that is close with running channel 8 is more abundant; Organize more granular, intensity is higher.

(5) a kind of casting method; The alloy liquation is injected die casting tube 12; Then with mold cavity 9 injections of alloy liquation behind matched moulds; Make cast product, wherein open ultrasonic wave generation and the control device 11 that links to each other with running channel 8 when die casting tube 12 is flowed through running channel 8, running channel 8 and die casting tube 12 interior liquations are applied ultrasonic vibration when the alloy liquation injects; The ultrasonic waves that link to each other of opening mold vibrating member 10 take place and control device 11 again when said liquation begins to get into die cavity 9, and running channel 8 is united with vibrating member 10 liquations in the mold cavity 9 are applied ultrasonic vibration, processes the foundry goods goods until solidifying.

Therefore, compare prior art, can prolong the ultrasonic vibration time, the hole that can effectively utilize ultrasonic vibration to produce promotes the formation of a plurality of dendrite, and dendrite fragmentation made organizes further granular.
