According to the gas-liquid conversion principle of the closed container, nitrogen with certain pressure is filled into the quantitative cylinder body, the charging time is controlled, and the control cylinder is matched to control the flow direction of the melt liquid to realize quantitative conveying. The device can realize stable, clear ration pay-off, improves work efficiency, reduction in production cost.
Description
Technical field: the utility model relates to a kind of die casting machine quantitative feed device, is mainly used in the extrusion process of magnesium alloy.
Background technology: the material mode is manually watered in the many employings of the production of traditional magnesium alloy die casting, waters the how much wayward of material feeding, occurs the waste of material easily; And magnesium alloy is easy to oxidizing fire, so fusing, insulation the time need flux to cover, impurity can be brought into when manually getting material from the top, defective such as cause that product is mingled with, and percent defective is higher, thereby makes production cost higher.
Summary of the invention: the utility model is in order to overcome the deficiency of manually watering material, guarantee product quality, and improve working environment, improve the safety in production coefficient, a kind of die casting machine pneumatic type magnesium-alloy quantitative pay-off is provided, it is characterized in that: described pay-off mainly comprises mechanical shut-off valve, material storing box, quantitative cylinder body, magnetic valve, control cylinder, the insulation conveyance conduit, described quantitative cylinder body is fixed by frame, place material storing box, one end is communicated with the two-position three way magnetic valve of being controlled by time controller by pipeline, other end bottom is provided with charging aperture, top has discharging opening to connect described insulation conveyance conduit, described mechanical shut-off valve is positioned at cylinder body and connects with the linkage of described air cylinder driven, and described linkage is fixed on the bottom of described material storing box, and links with control cylinder.
This device charges into the nitrogen of certain pressure according to closed container gas-liquid transfer principle in quantitative cylinder body, control its inflationtime, and is equipped with quantitative conveying of control cylinder control liquation flow direction realization; Generally be no more than 5% because the volume that the decline liquid level causes increase is compared with original volume, thereby can guarantee less feeding error, meet the extrusion process requirement.Therefore in magnesium alloy member die casting production process, can realize the quantitative conveying of magnesium alloy liquation, substitute and manually water material, improve operating efficiency, safety coefficient and product quality, reduce production cost.
Description of drawings: Fig. 1 is this die casting machine pneumatic type magnesium-alloy quantitative pay-off schematic diagram;
Fig. 2 is the feed state figure of this die casting machine with pneumatic type magnesium-alloy quantitative pay-off;
Fig. 3 is the discharging state diagram of this die casting machine with pneumatic type magnesium-alloy quantitative pay-off.
The specific embodiment: as shown in Figure 1, this die casting machine uses pneumatic type magnesium-alloy quantitative pay-off according to closed container gas-liquid transfer principle, in quantitative cylinder body, charge into the nitrogen of certain pressure, adopt time controller control two-position three way magnetic valve, control charges into the time of nitrogen in the quantitative cylinder body, make the nitrogen given volume that charges in the airtight cylinder body, be equipped with control cylinder and control the flow direction of alloy liquation in the airtight cylinder body, it is exactly certain then spilling into the liquation volume that is incubated conveyance conduit from discharging opening, thereby realizes quantitative feed.According to basic physics theory, along with the decline of liquid level, it is big that gas volume becomes, the liquation that extrudes reduces, calculate through the mole theorem: the volume increase that the decline liquid level causes is compared with original volume and generally is no more than 5%, thereby can guarantee less feeding error, meets the extrusion process requirement.
Its concrete structure such as Fig. 2, shown in Figure 3, comprise mechanical shut-off valve 1, material storing box 2, quantitative cylinder body 3, magnetic valve 5, control cylinder 7, insulation conveyance conduit 8, wherein quantitatively cylinder body 3 is fixed by frame, place material storing box 2, one end is communicated with magnetic valve 5 by pipeline, magnetic valve 5 is the two-position three way magnetic valves by time controller control, and the other end is controlled the keying of discharging opening 9 and charging aperture 10 by the mechanical shut-off valve 1 that is positioned at cylinder body; Discharging opening 9 connects insulation conveyance conduit 8.Stop valve 1 connects with the linkage 11 that control cylinder 7 drives, and linkage 11 is fixed on the bottom of material storing box 2.The charging into the time of nitrogen when the discharge of gas and discharging in the quantitative cylinder body 3 is equipped with control cylinder 7 drivening rod mechanisms 11 when adopting two-position three way magnetic valve 5 control chargings, and 1 switch of control mechanical shut-off valve is realized the quantitative cylinder body 3 of turnover of alloy liquid.Wherein quantitatively cylinder body 3 can not exclusively be positioned at material storing box 2, as long as charging aperture 10 is communicated with material storing box 2.
Feed state as shown in Figure 2, control cylinder 7 retreats pulling linkage 11, and to drive mechanical shut-off valve 1 descending, opens the charging aperture 10 that communicates with material storing box, seals discharging opening 9 simultaneously; The two-position three way magnetic valve 5 of time controller control simultaneously is to shown position, and gas is discharged by blast pipe 4, and quantitatively cylinder body 3 is in exhaust condition, and the alloy liquation in the material storing box 2 enters quantitative cylinder body 3 through mechanical shut-off valve 1, realizes charging.
The discharging state as shown in Figure 3, time controller control two-position three way magnetic valve 5 is closed quantitative cylinder body 3 exhaust outlets to shown position, connects the interface 6 that communicates with certain pressure nitrogen, charges into nitrogen; Simultaneously, control cylinder 7 advances and promotes linkage 11, makes mechanical shut-off valve 1 up, closes charging aperture 10, opens discharging opening 9, and alloy liquid is transported on the die casting machine by insulation conveyance conduit 8 under the nitrogen compressing of certain pressure, finishes feeding.
This die casting machine just can be realized quantitatively what the adjustment of alloy liquid with pneumatic type magnesium-alloy quantitative pay-off by the time parameter of adjusting the time controller setting.Simultaneously, this device is got material from material storing box 2 middle parts, has prevented to bring into impurity such as solvent, has guaranteed the cleaning feed.
