Description
Technical field
The utility model relates to aluminum casting gravity casting machinery, is specifically related to hydraulic pressure cast aluminium gravity force casting machine.
Background technology
Gravity force casting machine of the prior art; Like disclosed a kind of casting machine in the Chinese patent 200520126167.9, as shown in Figure 1, the both sides of frame 1 are provided with the hydraulic cylinder 10 that connects with mould 2; Lay the mould 2 that can laterally move, be two slit bamboo or chopped wood clamshell type on the frame 1; Be provided with locking device 7 between the two slit bamboo or chopped wood moulds 2, the sprue-way 11 that the chassis 4 frame downside, that can vertically move is provided with locator and is communicated with middle cast tube 5, mould 2 die cavities, 4 upper surfaces, chassis abut against mould 2; Chassis 4 downsides are provided with lifting device, and last feeding device 3 is located at the upper end of mould 2.A plurality of mould 2, chassis 4 also can be set on the frame 1.
The type of existing hydraulic pressure cast aluminium gravity force casting machine all is on mould bases, to open the T groove, or on mould bases, punches; With fixed mould, mould and mould bases are close together, this just caused mould eject the hole site must with mould bases preformed hole position consistency; Otherwise, can not use; On the other hand, the mould knock-pin must pass through mould bases, and mould bases and Mould design have been proposed very high requirement, and both design must be consistent; To new mould, then must join and beat jogger hole through the dismounting mould bases, just can use.Therefore, caused very big workload, installed the too many time of waste at the supporting of mould and mould bases.So, the obvious deficiency that exists in actual use.Mainly contain following two aspects:
1) in common hydraulic pressure cast aluminium gravity force casting machine type, do not consider installing additional of mould, have only the reservation of Mold Base Design to eject the hole site and the design of mould knock-pin is consistent, can use.Otherwise, must dismounting equipment, again mould bases is joined punching, adapting to the mould knock-pin, thus mould install additional very inconveniently, also increased workload.
2) liftout attachment on the common hydraulic pressure cast aluminium gravity force casting machine mould bases generally is not consider mould, moreover mould is to tighten together with mould bases, just on mould bases, opens the T groove; Or on mould bases, punch, with fixed mould, therefore; If the knock-pin of mould can only be dismantled mould bases inconsistent with mould bases, resets push rod and ejects the hole; To adapt to mould knock-pin position, bring very big inconvenience to production, knock-pin is long also to cause adverse influence to product quality.
Summary of the invention
Because liftout attachment on the common hydraulic pressure cast aluminium gravity force casting machine mould bases and mould install additional and exist tangible deficiency, production brings very big inconvenience to cast aluminium, has both influenced workpiece quality, influences manufacturing schedule again, causes material and artificial waste.Therefore; For overcoming the existing technical deficiency of common hydraulic pressure cast aluminium gravity force casting machine, provide a kind of simple to operate, more mold exchange is simple and easy; It is very urgent to eject the lower hydraulic pressure cast aluminium gravity force casting machine of workpiece convenience and manufacturing cost; For this reason, the utility model cast aluminium gravity force casting machine that we develop can remedy the deficiency of above technical elements.
The technical scheme that realizes the purpose of the utility model is: hydraulic pressure cast aluminium gravity force casting machine; Comprise frame, both sides location-plate, the axis of guide, mould bases, mould, workpiece liftout attachment, bidirectional hydraulic oil cylinder, mold platform and lowering or hoisting gear; Two symmetries were fixed on the upper surface of frame about said location-plate, mould bases and mould were; Ecto-entad is followed successively by location-plate, mould bases and mould; Through location-plate four jiaos of four said axis of guides are fixedly connected with left and right sides location-plate, and four said axis of guides pass four jiaos of said mould bases, slidably are connected with said mould bases; The outside of location-plate is respectively equipped with said bidirectional hydraulic oil cylinder in the left and right sides, and the oil cylinder of said bidirectional hydraulic oil cylinder is connected with said mould bases, for laterally moving of mould bases provides power; Between said mould bases and mould, leave the gap, said workpiece liftout attachment is arranged in the gap, connects mould bases and mould, and regulates the gap between mould bases and the mould; Said lowering or hoisting gear is fixed on the base of frame, is connected with mold platform.
The preferred structure of said workpiece liftout attachment is: said workpiece liftout attachment comprises that liftout plate, locating shaft and workpiece eject backstay; Said liftout plate is a surface plate; Be fixed on the supporting axle, supporting axle is fixed on the said mould bases, and mould is connected on the mould bases through locating shaft; Liftout plate is positioned between mould and the mould bases through supporting axle, and said die face is provided with workpiece to the one side of liftout plate and ejects backstay.
As the further improvement of the utility model, the movable die supports and mold that said mould bases bottom surfaces is provided with the one side of mould, the level height that is used to support and regulate mould.
The utility model multi-functional mechanical provides a kind of gravity casting equipment of steel die cast aluminum component, with respect to existing gravity casting machinery, has some following advantages:
1) this equipment is applicable to the aluminium alloy casting spare of plurality of specifications and shape, and the scope of application is wide;
2) die change is convenient, and positioning stablity can easily be fixed on the mould bases mould not of the same race easily, thereby saves the more mold exchange time greatly owing to place the change of mould structure design, uses manpower and material resources sparingly, and has improved operating efficiency;
3) steadily strong this equipment of folding mould has designed whole guiding group system, has changed the deficiency of the operating balance of equipment;
4) easy and simple to handle, the automatic depanning of workpiece, push rod self-return.This equipment has designed whole template liftout attachment, need not design knock-pin separately to various mould, after workpiece ejects, gets final product self-return;
5) according to the characteristic of difformity workpiece, can multidirectionally loose core multidirectional matched moulds.
Beneficial effect:
Because the utility model hydraulic pressure cast aluminium gravity force casting machine has fundamentally improved the deficiency of original casting machine, thereby saves the die change time widely, use manpower and material resources sparingly, in the face of a large amount of gravity casting aluminum component in the domestic and international machinery manufacturing industry; Particularly external purchase order all is that the duration is short usually, and task is heavy, and is wide in variety; Quality requirement is high, needs a good production run state, can in time supply, and obtains client's prestige; Simultaneously, hydraulic pressure cast aluminium gravity force casting machine also is a kind of equipment of efficient and environment-friendly type, has the production efficiency height, constant product quality; Advantages such as workpiece accuracy is high, and raw material are saved, and the waste product material is few; Therefore, the renewal of the utility model technology has vast market prospect.
