Compared with the prior art, the utility model has the advantages of the aluminium liquid of this mould air discharge duct structure departure can solidify and fill the clearance between coagulum and the cope match-plate pattern in the coagulum, guarantees that aluminium liquid can't fly into to the template in through the coagulum, avoids the mould to be crushed.

Description

mould air discharge duct structure

Technical Field

The utility model belongs to the technical field of the mould, concretely relates to mould air discharge duct structure.

Background

The phenomenon of flying aluminum at the exhaust position can be met usually when die-casting is carried out, in the full-automatic production process of die-casting, prevent that the mould from flying aluminum and be the key problem of guaranteeing the full-automatic stable production of die-casting, the aluminium liquid of departure can not solidify in the twinkling of an eye because the temperature is higher, and because the reason of cost between the cope and drag template, can have the clearance between the two, and then aluminium liquid can get into in the clearance between the supreme lower bolster in a large number, under the untimely condition of flying the aluminium clearance, the aluminium sediment can be amasss more, finally lead to the mould to be crushed and need machine repair the mould.

SUMMERY OF THE UTILITY MODEL

the utility model aims to solve the technical problem that to prior art's current situation, and provide a mould air discharge duct structure.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a mold vent structure is provided, comprising: mounting a template;

The lower template is positioned below the upper template, the upper end face of the lower template movably abuts against the lower end face of the upper template, a plurality of exhaust grooves are formed in the lower template, a plurality of coagulating grooves are further formed in the lower template, and each coagulating groove is formed in the periphery of the exhaust groove.

In the above-mentioned mold vent groove structure, the depth of each of the solidification grooves is between 0.3mm and 0.7 mm.

In the above-mentioned one mold vent groove structure, the width of each of the solidification grooves is between 4mm and 6 mm.

Compared with the prior art, the utility model has the advantages of the aluminium liquid of this mould air discharge duct structure departure can solidify and fill the clearance between coagulum and the cope match-plate pattern in the coagulum, guarantees that aluminium liquid can't fly into to the template in through the coagulum, avoids the mould to be crushed.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 4, the present mold vent 3 structure includes: an upper template 1; the lower template 2 is positioned below the upper template 1, a plurality of exhaust grooves 3 are formed in the lower template 2, a plurality of coagulating grooves 4 are further formed in the lower template 2, and each coagulating groove 4 is arranged at the periphery of each exhaust groove 3.

The coagulating bath 4 is positioned at the periphery of the exhaust groove 3, when the die is closed and die-cast, the aluminum liquid enters the template, because the temperature of the aluminum liquid is higher, the gas in the aluminum liquid can be discharged and enter the exhaust groove 3, and because the pressure is higher in the process that the gas enters the exhaust groove 3, the gas can carry the aluminum liquid out and fly out, when the flying aluminum liquid touches the inner wall of the exhaust groove 3, the flying aluminum liquid can be solidified on the inner wall of the exhaust groove 3, but simultaneously a part of the aluminum liquid can fly into the coagulating bath 4, when the aluminum liquid enters the coagulating bath 4, the aluminum liquid can be solidified on the coagulating bath 4, during the die-casting process, the aluminum liquid can continuously enter the coagulating bath 4 and be solidified in the coagulating bath 4, the process is repeated until the solidified aluminum liquid in the coagulating bath 4 is filled in the gap between the lower end face of the upper template 1 and the coagulating bath 4, and the flying aluminum liquid can not enter the gap between the upper template 1 and the lower template, the mould is guaranteed not to be damaged.

During mold opening, aluminum liquid cannot enter a gap between the upper template 1 and the lower template 2, so that only aluminum slag in the coagulating tank 4 and the exhaust groove 3 needs to be cleaned, and the workload of operators is greatly reduced.

The depth of each coagulation tank 4 is between 0.3mm and 0.7 mm.

the width of each coagulation tank 4 is between 4mm and 6 mm.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
