Abstract
The utility model discloses a mold cavity vacuumizing die-casting mold and aims at providing a cavity vacuumizing die-casting mold capable of improving the cast product quality. The die-casting mold comprises an exhaust groove (2) and a concentrated exhaust groove (3) which are formed in a fixed mold (1), and also comprises a vacuumizing hole (5) and a piston (6) which arranged on a movable mold (4), wherein the exhaust groove (2) surrounds a cavity and is communicated with the concentrated exhaust groove (3); The piston (6) is arranged in a connecting channel of the concentrated exhaust groove (3) and the vacuumizing hole (5) and can be used for controlling the connection and disconnection of the concentrated exhaust groove (3) and the vacuumizing hole (5); the vacuumizing hole (5) is connected with a pipeline of a vacuum pump. The cavity vacuumizing die-casting mold is mainly applied to the field of mold forming.
Description
Technical field
The utility model relates to a kind of die cavity and vacuumizes compression mod.
Background technology
In die casting is produced, the gas discharging in die cavity has directly had influence on the quality of foundry goods.The foundry goods of common extrusion process has pore to exist, this is during due to die casting, metal is filled die cavity with high velocity jet state, gas in die cavity has little time to get rid of and is inevitably rolled in molten metal, thereby produces gas hole defect, has reduced casting quality, air porous expanded meeting is heaved cast(ing) surface when high temperature in addition, have a strong impact on casting of appearance of cast, be unfavorable for product surface processing, reduced its overall mechanical property.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of die cavity that improves casting quality to vacuumize compression mod.
The technical scheme that the utility model adopts is: a kind of die cavity vacuumizes compression mod, it comprises the air discharge duct and the concentrated air discharge duct that are arranged on cover half, it also comprises being arranged on and vacuumizes hole and piston on dynamic model, described air discharge duct is communicated with around die cavity and with described concentrated air discharge duct, described piston be arranged on described concentrated air discharge duct with described in vacuumize in interface channel on hole and can control described concentrated air discharge duct with described in vacuumize hole and connect and sealing, described in take out true hole and be connected with the pipeline of vavuum pump.
Described vavuum pump with described in vacuumize on the connecting line in hole and be provided with vacuum valve.
The beneficial effects of the utility model are: because the utility model comprises the air discharge duct and the concentrated air discharge duct that are arranged on cover half, it also comprises being arranged on and vacuumizes hole and piston on dynamic model, described air discharge duct is communicated with around die cavity and with described concentrated air discharge duct, described piston be arranged on described concentrated air discharge duct with described in vacuumize in interface channel on hole and can control described concentrated air discharge duct with described in vacuumize hole and connect and sealing, describedly take out true hole and be connected with the pipeline of vavuum pump, pass through the utility model, gas in mold cavity can be discharged, thereby can guarantee whole foundry goods in forming process in vacuum state, thereby guarantee can foundry goods quality.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the fixed mould structure schematic diagram of the utility model embodiment.
Detailed description of the invention
As Fig. 1, Figure 2 shows that a kind of die cavity vacuumizes compression mod, it comprises the air discharge duct 2 and the concentrated air discharge duct 3 that are arranged on cover half 1, it also comprises being arranged on and vacuumizes hole 5 and piston 6 on dynamic model 4, described air discharge duct 2 is communicated with around die cavity and with described concentrated air discharge duct 3, described piston 6 be arranged on described concentrated air discharge duct 3 with described in vacuumize in the interface channel on hole 5 and can control described concentrated air discharge duct 3 with described in vacuumize hole 5 and connect and sealing, describedly take out true hole 5 and be connected with the pipeline of vavuum pump, described vavuum pump with described in vacuumize on the connecting line in hole 5 and be provided with vacuum valve, this die cavity vacuumizes compression mod and works under control system effect.
Operation principle: when molten metal filing fills up after described concentrated air discharge duct 3, described piston 6 is pushed up go back to left side, just in time by described concentrated air discharge duct 3 with described in vacuumize the interface channel sealing in hole 5, now under described control system effect, described vacuum valve cuts out, die sinking is taken out after foundry goods, described piston 6 turns back to original position under described control system effect, described concentrated air discharge duct 3 with described in vacuumize hole 5 interface channel connect, in the time that drift passes through pressure chamber pouring slot, start at vavuum pump described in described control system effect, start to take out the gas in die cavity.
Claims (2)
1. a die cavity vacuumizes compression mod, it is characterized in that: it comprises the air discharge duct (2) and the concentrated air discharge duct (3) that are arranged on cover half (1), it also comprises being arranged on and vacuumizes hole (5) and piston (6) on dynamic model (4), described air discharge duct (2) is communicated with around die cavity and with described concentrated air discharge duct (3), described piston (6) be arranged on described concentrated air discharge duct (3) with described in vacuumize in interface channel on hole (5) and can control described concentrated air discharge duct (3) with described in vacuumize hole (5) and connect and sealing, the described true hole (5) of taking out is connected with the pipeline of vavuum pump.
