Abstract
The utility model discloses an exhaust structure of a die-casting mold cavity. The exhaust structure of the die-casting mold cavity is used for improving the blocking capacity, reducing the kinetic energy of the molten aluminum, reducing the speed of the molten aluminum and increasing the service life of an exhaust pipeline; the air pressure in the cavity is greatly reduced by virtue of exhausting so that the product quality can be improved. The exhaust structure of the die-casting mold cavity comprises a fixed mold and a movable mold; cavities are formed inside the fixed mold and a movable mold; the exhaust structure is characterized in that an exhaust channel is communicated with one sides of the cavities and composed of a fixed mold exhaust block and a movable mold exhaust block, the fixed mold exhaust block is fixedly connected to the fixed mold at the top of the fixed mold exhaust block, while the movable mold exhaust block is fixedly connected to the movable mold at the bottom of the movable mold exhaust block, the exhaust channel comprises an air inlet, a waved wide-face runner and an air outlet, the rear part of the air outlet is connected to the inlet of the vacuum valve, and the outlet of the vacuum valve is connected to the air suction inlet of a vacuum pump by use of a vacuum pipeline.
Description
Technical field
The utility model relates to mould structure technical field, is specially a kind of exhaust structure of die casting die cavity.
Background technology
In the die cavity of existing die casting, in press casting procedure, can produce gas, gas need to be by discharging die cavity with the exhaust structure of die cavity connection, and also otherwise allow the aluminium liquid in die cavity flow out, existing exhaust structure reduces aluminium liquid speed by design the bending of a plurality of 90 degree in horizontal plane, but aluminium liquid Speed Reduction is not obvious in actual production, speed or too fast after induction, cause evacuating valve to occur closing not dead situation, make aluminium liquid enter into discharge duct, easily cause discharge duct to block.
Summary of the invention
For the problems referred to above, the utility model provides a kind of exhaust structure of die casting die cavity, and it has strengthened blocking capability, reduce the kinetic energy of aluminium liquid, reduce aluminium liquid speed, the service life of improving discharge duct, and use is bled the pressure decreased of the gas in die cavity is more, improve the quality of product.
A kind of exhaust structure of die casting die cavity, its technical scheme is such: it comprises cover half, dynamic model, described cover half, dynamic model inside is provided with die cavity, it is characterized in that: a side of described die cavity is communicated with exhaust passage, described exhaust passage is by cover half exhaust block, both are combined to form moving die exhaust block, described cover half exhaust block is fastenedly connected the described cover half on its top, described moving die exhaust block is fastenedly connected the described dynamic model of its underpart, described exhaust passage comprises air inlet, the wide surface current of wave road, gas outlet, the rear portion of described gas outlet connects the entrance of vacuum valve, the outlet of described vacuum valve connects the suction inlet of vavuum pump by vacuum pipe.
It is further characterized in that:
The surrounding of the lower surface of described cover half exhaust block, moving die exhaust block upper surface fits tightly, and the air inlet, the middle part horizontal direction that form front end linear pattern slot form the wide surface current of the wave road that facade is wave structure, the gas outlet of rear end linear pattern slot, the die joint of described die cavity is communicated to described air inlet, the width in the wide surface current of described wave road is greater than the cross-sectional width of described air inlet, and the width in the wide surface current of described wave road is greater than the cross-sectional width of described gas outlet;
Between the installed surface of described cover half exhaust block and described cover half, be provided with locating convex block structure, between the installed surface of described moving die exhaust block and described dynamic model, be provided with lower locating convex block structure.
Adopt after structure of the present utility model, owing to having adopted the wide surface current of wave road, damping increases, it makes aluminium liquid in motion process, be subject to very large stopping, reduce the kinetic energy of aluminium liquid, reduce aluminium liquid speed, improve the service life of discharge duct, in addition, because the rear portion of gas outlet connects the entrance of vacuum valve, the outlet of described vacuum valve connects the suction inlet of vavuum pump by vacuum pipe, and use is bled the pressure decreased of the gas in die cavity is more, gas while making die-cast product in die cavity still less, improves the quality of product.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model (removing exhaust passage exterior line);
Fig. 2 is the syndeton top view of exhaust passage and exterior line.
