Description
Technical field
The utility model relates to a kind of casting device, specifically a kind of vacuum centrifugal casting device.
Background technology
Vacuum centrifugal casting is a kind of novel casting method that vacuum pressing and casting combines with centrifugal casting, and it places shaping mechanism in one seal closure, seals with clay or sealing strip around the seal closure as far as possible, and seal with foam or plastic flower the cast porch.Before the cast, the synthetic foundry goods die cavity of upper and lower mould is also pressed the setting speed rotation, and vacuum system is through the aspirating hole of sealing device, directly extract out in the seal closure and the gas in the foundry goods die cavity, make it reach predetermined vacuum, set up parital vacuum (negative pressure), make the foundry goods die cavity be in vacuum (negative pressure) state.During cast, liquation charges into the foundry goods die cavity inside that is vacuum and rotation through running gate system fast, cast is bled, rotation, all the time keep certain vacuum and centrifugal force, make liquation crystallization and freezing in this environment, after foundry goods is finished liquid contraction and solidification shrinkage, close vacuum system, stop the rotation the opening encapsulation cover door and the demoulding.Since the centrifugal force that the foundry goods die cavity produces when being in vacuum (negative pressure) state and liquid and the rotation of foundry goods die cavity, the mold-filling capacity when improving the metal casting shaping greatly, gas is easily discharged when filling type, and bleb is few, and can improve THE STRUCTURE OF CASTINGS compactness.But, because sky is too big in the seal closure, cause rate of air sucked in required big, and seal closure junction sealing difficulty is big, be sealed with difficulty fully, thereby it is big to cause vacuum to improve difficulty.Simultaneously, owing to there is seal closure, the cast passage is longer, and the casting process temperature descends too fast, and the bad control of pouring temperature is more obvious for the small-sized foundry goods of cast.
Summary of the invention
The purpose of this utility model provides the little vacuum centrifugal casting device of a kind of rate of air sucked in required.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of vacuum centrifugal casting device, it comprises rack-mounted power, by the power transmission shaft of power by the transmission device drive, power transmission shaft one end is connected with hoist cylinder, the other end passes rack-mounted lower platen and is connected with the counterdie mount pad, Connection Block, counterdie, patrix and patrix mount pad are mounted on the counterdie mount pad by guide rod, and make patrix and counterdie matched moulds, form airtight shaping mechanism, counterdie, patrix is formed the foundry goods die cavity, and the foundry goods die cavity is provided with air flue, counterdie outward, patrix is provided with the ventilation grain that the foundry goods die cavity is communicated with air flue; Lower platen is equipped with upper platen by column, and upper platen is provided with cup, and cup is communicated with the foundry goods die cavity by running channel; Described power transmission shaft is a hollow shaft, and an end is communicated with the foundry goods die cavity by air flue, and the other end is connected with the air extraction connector seat by plane bearing, and the air extraction connector seat is provided with air extraction connector.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, vacuumized by vacuumizing to change into from foundry goods die cavity inside from seal closure originally, good airproof performance vacuumizes volume and dwindles greatly, to most products, be less than original 1/10th, effective gas clean-up, simultaneously, the cast passage obviously shortens, and less than half original length, shorten the duration of pouring, pouring temperature and forming temperature change very little, are easy to control.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, frame 11 tops are provided with seal closure 20, and seal closure 20 is provided with air extraction connector 13, and the shaping mechanism of being made up of Connection Block 5, counterdie 4, patrix 17 and patrix mount pad 3 is arranged in the seal closure 20.During work, because sky is too big in the seal closure 20, cause rate of air sucked in required big, arrow is depicted as air direct among Fig. 1, and sealing difficulty is big, thereby it is big to cause vacuum to improve difficulty.Simultaneously, owing to there is seal closure 20, running channel 19 is longer, and the casting process temperature descends too fast, and the bad control of pouring temperature is more obvious for the small-sized foundry goods of cast.
As shown in Figure 2, a kind of vacuum centrifugal casting device, it comprises the power 14 (present embodiment is a motor) that is installed on the frame 11, by the power transmission shaft 10 of power 14 by the transmission device drive, power transmission shaft 10 1 ends are connected with hoist cylinder 12, the other end passes the lower platen 9 that is installed on the frame 11 and is connected with counterdie mount pad 7, Connection Block 5, counterdie 4, patrix 17 and patrix mount pad 3 are mounted on the counterdie mount pad 7 by guide rod 6, and make patrix 17 and counterdie 4 matched moulds, form airtight shaping mechanism, counterdie 4, patrix 17 is formed foundry goods die cavity 15, the foundry goods die cavity 15 outer air flues 16, counterdie 4 of being provided with, patrix 17 is provided with the ventilation grain 18 that foundry goods die cavity 15 is communicated with air flue 16; Lower platen 9 is equipped with upper platen 2 by column 8, and upper platen 2 is provided with cup 1, and cup 1 is communicated with foundry goods die cavity 15 by running channel 19; Described power transmission shaft 10 is a hollow shaft, and an end is communicated with foundry goods die cavity 15 by air flue 16, and the other end is connected with the air extraction connector seat by plane bearing, and the air extraction connector seat is provided with air extraction connector 13.
When the utility model used, sealed with foam or plastic flower the cast porch.Before the cast, counterdie 4, patrix 17 synthesize foundry goods die cavities 15 and press the setting speed driven rotary by power transmission shaft 10.Vacuum plant is through air extraction connector 13, with extraction in the cavity of the air in the foundry goods die cavity 15 through forming between ventilation grain 18, air flue 16, counterdie mount pad 7 and the Connection Block 5, the power transmission shaft 10, shown in arrow among Fig. 2, make foundry goods die cavity 15 be in vacuum (negative pressure) state.Liquation during cast (present embodiment is an aluminium liquid) charges into foundry goods die cavity 15 inside that are vacuum and rotate simultaneously through running gate system fast.Bleed, rotate, keep certain vacuum and centrifugal force all the time, make aluminium liquid crystallization and freezing in this environment, after foundry goods is finished liquid contraction and solidification shrinkage, close vacuum system, stop the rotation, foundry goods is taken out in the demoulding.
The utility model vacuumized by vacuumizing to change into from shaping mechanism inside from seal closure 20 originally, good airproof performance vacuumizes volume and dwindles greatly, to most products, be less than original 1/10th, effectively gas clean-up simultaneously, is poured into a mould passage and is obviously shortened, less than half original length, shorten the duration of pouring, and pouring temperature and forming temperature change very little, is easy to control.
The utility model is applied to the casting of special-shaped part, can cast a plurality of special-shaped casts simultaneously in same casting die, significantly improves the economic benefit of casting shaped piece, for casting special-shaped part has sizable advantage of striving unexpectedly in batches.
