Description
Technical Field
The utility model relates to the field of die-casting molds, in particular to a die-casting mold with small filling resistance.
Background
The die-casting and casting industry in China develops rapidly, the prospect is very optimistic, and the die-casting die industry is also driven along with the rise of related industries such as automobiles and the like. But the development still faces many bottlenecks, the technical innovation is always the hard damage of the domestic die industry, the output of the low-end die is overlarge, the production of the high-end die is insufficient, particularly the level of the technical field of die design is not high, the technical innovation in the aspect of die design is lacked, and the urgent need is for improving the productivity and the international influence in the die-casting and die industries.
In the existing die-casting die, a main pouring gate and a straight pouring gate are connected at 90 degrees, the pouring path of the main pouring gate is long, a large amount of scrap returns are generated in the production process of a product, meanwhile, the local pressure and the on-way pressure loss of molten metal in the pouring process are large, the energy consumption is high, particularly, turbulence and air entrainment are easily generated at a 90-degree corner, and the quality of die-casting products is influenced.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides the die-casting die with low filling resistance, which is simple in structure, and is beneficial to shortening the pouring channel path and reducing the filling resistance.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a die casting die that filling resistance is little which characterized in that: including just to cover half and the movable mould of arranging, the die cavity that forms the product has on cover half and the movable mould, be provided with the runner cover on the cover half, be provided with the sprue spreader on the movable mould, the sprue bushing cover is established the sprue spreader upper end, have between cover half and the movable mould to the oblique die joint of cover half one side slope, oblique die joint is followed the die cavity edge extends to the material export of sprue spreader it has sprue, cross gate and the branch that connects gradually to distribute on the oblique die joint.
Further, the inclination angle of the inclined parting surface is 25-40 degrees.
Further, the straight pouring channel and the cross pouring channel are located on one side of the fixed die.
Further, one of the runners is divided into two of the runners to both sides, and each of the runners is divided into three of the branch runners.
The beneficial effects of the utility model include: the weight of the pouring gate is reduced by about 20 percent, the raw material remelting loss can be greatly reduced, the local pressure loss and the on-way loss of molten metal can be reduced, the energy consumption is reduced, the service life of the die is prolonged, the generation of turbulence at corners is reduced, and the gas entrainment probability is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the runner structure of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
A die casting mold as shown in FIGS. 1-2, which is advantageous in reducing filling resistance, has a structure comprising a stationary mold 1 and a movable mold 2 arranged to face each other. The fixed die 1 and the movable die 2 are provided with a cavity 3 for forming a product. A sprue bush 4 is arranged on the fixed die 1; the movable mold 2 is provided with a sprue spreader 5, and the sprue bush 4 is sleeved at the upper end of the sprue spreader 5, so that a main sprue of the mold is formed. Have the oblique die joint 6 to the slope of cover half 1 one side between cover half 1 and movable mould 2, this oblique die joint 6 extends to the material export of reposition of redundant personnel awl 5 from the die cavity 3 edge, distributes on oblique die joint 6 and has sprue 7, cross gate 8 and the branch that is connected to die cavity 3 in proper order and waters 9. This arrangement avoids a 90 turn between the main runner and the sprue 7.
According to the utility model, the inclination angle of the inclined parting surface 6 is set to be 25-40 degrees selectively according to the size of the die, the distribution of pouring channels is facilitated within the angle range, and meanwhile, the on-way pressure loss of molten metal is favorably slowed down, the power consumption of a die casting machine is favorably reduced, and the service life of the die is prolonged.
As shown in FIG. 2, in the present embodiment, the sprue 7 and the runner 8 are located on the fixed mold 1 side, and the side take-out member is demolded together with the runner.
In the present embodiment shown in fig. 2, one sprue 7 is divided into two runners 8 to both sides, and each runner 8 is divided into three branch runners 9. The structure is beneficial to the metal liquid to fill the die cavity quickly, and the phenomenon that the pressure loss is large due to too long metal liquid filling path is avoided, so that the product quality is influenced.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
