Abstract
The utility model discloses an aluminum die exhaust device, which comprises a body, wherein a cavity is arranged in the center of the body, a plurality of fan-shaped bosses are arranged on the outer side of the cavity, an exhaust groove is formed between two adjacent fan-shaped bosses, an exhaust port is arranged at one end of the exhaust groove far away from the cavity, and the shape of the exhaust port is semicircular; the exhaust port is arranged at the tail end of the exhaust groove, so that the exhaust area is increased, and the gas in the die is well exhausted, thereby improving the exhaust effect and the product quality; the height of the fan-shaped boss is gradually reduced from the cavity to the outside, so that the exhaust area of the exhaust groove is indirectly increased, and the exhaust effect is further improved.
Description
Technical Field
The utility model relates to a casting equipment technical field, concretely relates to aluminum mould exhaust apparatus.
Background
The low-pressure casting is to lift liquid metal to a permanent mold by using relatively low pressure (for example, about 1.2-1.3bar of aluminum solution) and solidify the liquid metal under the pressure, so that the casting has good formability, is favorable for forming castings with clear outlines and smooth surfaces, and is more favorable for forming large thin-wall castings; compact casting structure and high mechanical property; but the existing aluminum die has poor exhaust effect, and causes the product to have bubbles, defects and the like, so that the product quality is lower.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an aluminum mould exhaust apparatus, simple structure can discharge the gas in the mould well to the quality of product has been improved.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an aluminum mould exhaust apparatus, includes the body, body central authorities are provided with the die cavity, the outside of die cavity is provided with a plurality of fan-shaped bosss, form the air discharge duct between two adjacent fan-shaped bosss, the one end that the die cavity was kept away from to the air discharge duct is provided with the gas vent, the shape of gas vent is semi-circular.
As a preferred technical solution of the present invention: the cavity is provided with a plurality of first exhaust grooves connected with the exhaust grooves, the number of the first exhaust grooves is half of that of the exhaust grooves, and the first exhaust grooves are connected with the exhaust grooves at intervals.
As a preferred technical solution of the present invention: the heights of the fan-shaped bosses are gradually reduced from the cavity to the outside.
As a preferred technical solution of the present invention: be provided with two relative screw holes on the body, fan-shaped boss has six, the air discharge duct has six, first air discharge duct has threely, air discharge duct and first air discharge duct cross sectional shape are the trapezoidal form of gradually increaseing from the outside opening of body.
The utility model discloses following beneficial effect has:
1. the exhaust port is arranged at the tail end of the exhaust groove, so that the exhaust area is increased, gas in the die is well exhausted, the exhaust effect is improved, and the product quality is improved.
2. The height of the fan-shaped boss is gradually reduced from the cavity to the outside, so that the exhaust area of the exhaust groove is indirectly increased, and the exhaust effect is further improved.

Detailed Description
In order to make the objects and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, an embodiment of the present invention provides an aluminum mold exhaust apparatus, which includes a body 1, wherein two opposite threaded holes 7 are provided on the body 1, and the arrangement of the threaded holes 7 facilitates the connection between the body 1 and other apparatuses; the center of the body 1 is provided with a cavity 2, the cavity 2 is taken as the center, a plurality of fan-shaped bosses 3 are arranged on the outer side of the cavity 2, an exhaust groove 4 is formed between two adjacent fan-shaped bosses 3, one end of the exhaust groove 4, which is far away from the cavity 2, is provided with an exhaust port 5, two ends of the outer side of each fan-shaped boss 3 are provided with smooth arc-shaped notches, and the two adjacent notches surround the exhaust port 5, so that the shape of the exhaust port 5 is semicircular; the exhaust groove 4 is arranged around the cavity 2, so that a plurality of exhaust grooves 4 are arranged around the cavity 2, the exhaust effect is good, the area of the exhaust port 5 is far larger than that of the exhaust groove 4, and the exhaust effect is improved.
The cavity 2 is provided with a plurality of first exhaust grooves 6 connected with the exhaust grooves 4, the number of the first exhaust grooves 6 is half of that of the exhaust grooves 4, the first exhaust grooves 6 are connected with the exhaust grooves 4 at intervals, namely, every other exhaust groove 4 has one exhaust groove 4 connected with the first exhaust groove 6, and the arrangement of the first exhaust grooves 6 prolongs the length of the exhaust grooves 4 and improves the exhaust effect; the preferred fan-shaped boss 3 has six, and exhaust duct 4 has six, and first exhaust duct 6 has three, and exhaust duct 4 and the first 6 cross sectional shapes of exhaust duct are the trapezoidal form that gradually increases from body 1 outside opening, and a plurality of fan-shaped bosses 3 highly outwards reduce gradually from die cavity 2 to increased exhaust area, improved exhaust effect.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
