Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a die casting die technical field specifically is a runner structure who relates to a die casting die.
[ background of the invention ]
Some metal workpieces are usually formed by die casting, and a die casting mold has an established runner structure and a cavity adjacent to the runner structure. During molding, molten metal soup can enter the cavity through the runner structure to be filled.
In the prior art, when a metal workpiece is molded, a gate of a runner structure is connected to a cavity of a mold through a large oblique angle at the male mold side of the mold, namely, the gate of the mold and the female mold side of the mold form a large impact angle. However, after the number of the mold production times of the gate of the runner structure in the prior art exceeds twenty thousand times, the surface of the die-casting mold has the defect of erosion, namely, the surface of the die-casting mold is sunken, and the sunken surface is enlarged into a pit along with continuous impact, even the sunken surface is connected with the pit, so that the mold is finally partially failed, and the mold repairing frequency is increased.
In view of the above, it is necessary to develop a runner structure of a die casting mold to solve the problem of erosion of the mold surface.
[ summary of the invention ]
Therefore, the utility model aims at providing a die casting die's runner structure, this runner structure can reduce the erosion to the mould, improves the mould life-span.
In order to achieve the purpose, the utility model discloses a die casting die's runner structure, this die casting die have public mould, master model, nozzle, runner structure and die cavity, and this runner structure includes the sprue and advances the runner, the nozzle is connected to sprue one end, advance the other end that the sprue was located to the sprue, advance runner horizontally connect the die cavity, just advance the runner evenly distributed in die casting die's public mould and master model.
Optionally, the die-casting mold is a mold with two cavities.
Optionally, the inlet gate is flat.
Optionally, the vertical sectional area of the gate from the main runner to the cavity direction is reduced from large to small.
Compared with the prior art, the utility model discloses a die casting die's runner structure advances runner horizontally connect through making the die cavity, just advance the runner evenly distributed in die casting die's public mould and master model, promptly advance the runner and all do not have public mould, master model and present impact angle, after production mould time surpassed two ten thousand times, die casting die surface still can not produce the defect of erosion. Therefore, the utility model discloses a die casting die's runner structure has reduced the erosion to the mould, has improved the mould life-span.

[ detailed description ] embodiments
For further understanding of the objects, technical effects and technical means of the present invention, reference will now be made in detail to the following description taken in conjunction with the accompanying drawings.
Referring to fig. 1 to 4, fig. 1 is a schematic view illustrating a runner structure of a die casting mold according to an embodiment of the present invention, fig. 2 is a partial enlarged view of fig. 1, fig. 3 is a schematic view illustrating another angle of the runner structure of the die casting mold according to the embodiment of the present invention, and fig. 4 is a partial enlarged view of fig. 3. Wherein because the runner structure presents the space for in the die casting die, and not express clearly easily, for express clearly the utility model provides a structure adopts the runner clout in the runner structure in the drawing (namely behind the shaping metal work piece, remaining clout in the runner structure, corresponding with the runner structure, and it is ejecting with the runner clout to need ejecting structure) form to express.
The utility model discloses a die casting die's runner structure, this die casting die are used for die-casting shaping metal work piece 10, die casting die has public mould, master model, nozzle, runner structure and die cavity, metal work piece 10 is by die-casting shaping in the die cavity, and wherein, this runner structure includes sprue 100 and advances runner 101, the nozzle is connected to sprue 100 one end, advance runner 101 and locate sprue 100's the other end, advance runner 101 horizontal connection the die cavity, just advance runner 101 evenly distributed in die casting die's public mould and master model.
Fig. 5 is a schematic view of a runner structure of a die casting mold according to a preferred embodiment of the present invention. The die-casting die is provided with two cavities in one die, namely when the metal workpiece 10 is die-cast and formed, the die-casting die simultaneously forms two completely same metal workpieces 10 in the processes of opening and closing the die in sequence, and the working efficiency is improved.
Wherein, the inlet gate 101 is flat, and accelerates to fill the metal soup material into the cavity.
The vertical cross-sectional area of the gate 101 from the main runner 100 to the cavity direction is reduced from large to small, so that the acceleration action can be realized in the filling process of the metal soup base, and the acceleration filling effect is further realized.
The utility model discloses a die casting die's runner structure, when shaping metal work piece 10, molten metal stock flows into main runner 100 from irritating the mouth, flows into runner 101 from main runner 100 after that, flows into die casting die's die cavity from advancing runner 101 again, and molten metal stock shaping is metal work piece 10 in the die cavity.
Compared with the prior art, the utility model discloses a die casting die's runner structure advances runner 101 horizontal connection through making the die cavity, just advance runner 101 evenly distributed in die casting die's public mould and master model, promptly advance runner 101 and all do not have with public mould, master model and present impact angle, after production mould time surpassed two ten thousand times, die casting die surface still can not produce the defect of erosion. Therefore, the utility model discloses a die casting die's runner structure has reduced the erosion to the mould, has improved the mould life-span.
