Abstract
The utility model discloses a kind of double formed punch injection structures of die casting machine, including framed, mold core, sprue bush, the mold core is fixed positioned on described framed interior, the sprue bush is embedded on the mold core, the sprue bush quantity is multiple, it is described it is framed on be connected with multiple pressure chambers for corresponding with the sprue bush and being connected to, and jumper bar axially movable is provided in each pressure chamber.The beneficial effects of the utility model include: the flowing time for substantially reducing molten metal in type chamber, while Multi-point supercharging and feeding may be implemented, and improve product quality, can also realize the high-pressure casting or multi-point mould casting of ultra-large type casting.
Description
Technical field
The utility model relates to field of die casting machines, and in particular to a kind of double formed punch injection structures of die casting machine.
Background technique
It is known that the working principle of die casting machine is that molten metal bath is poured into pressure chamber, molten metal is then pushed by formed punch
Indentation type chamber solidifies extrusion forming from low speed to high speed, and wherein the power resources of formed punch are discharged in the pressure of nitrogen gas tank, but by
For at present, we die casting machine be all the design of single formed punch, i.e., all power acted on molten metal are only derived from
One single-point, compared with light casting, there is no problem for most of volume or projected area for this mode, because of small-sized casting molten metal
Process it is short, the pressure loss is small, and single formed punch can be effectively pressurized and feeding before molten metal solidification, but very for some volumes
Greatly, the mode of single formed punch is just difficult to meet the requirements for the very big casting of projected area, because of large volume or big projected area
Casting long flow path, the molten metal of subsequent thermal also not in time supplement front end just solidified cold burden, this is also high die casting so far
Make one of the reason of cannot producing ultra-large type casting；In addition, some complex products are difficult to arrange two cave of a mould or multi-point mould,
It is because one-shot head the filling distance is too long, the pressure loss is larger, and one cave cost of a mould is again very high.
Summary of the invention
Place, the utility model provide a kind of double formed punch injection knots of die casting machine in view of the deficiency of the prior art
Structure, structure is simple, has multiple injection chambers, and run simultaneously, realizes the heavy castings die casting of multi-point mould and single cave.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of double formed punch injection structures of die casting machine, including framed, mold core, sprue bush, the mold core are fixed positioned on institute
State it is framed in, the sprue bush is embedded on the mold core, the sprue bush quantity be it is multiple, it is described it is framed on be connected with it is multiple
The pressure chamber being connected to is corresponded with the sprue bush, and is provided with jumper bar axially movable in each pressure chamber.
Further, it is additionally provided with cast gate more than one above the pressure chamber and melts cup, and more cast gates melt and are arranged on cup
Multiple flow-guiding mouths, and multiple flow-guiding mouth respectively corresponds the feed inlet of multiple pressure chambers.
Further, there is multiple type chambers, and each type chamber one sprue bush of corresponding connection on the mold core.
Further, there is a type chamber, and all sprue bush are connected to the type chamber on the mold core.
The beneficial effects of the utility model include: the flowing time for substantially reducing molten metal in type chamber, while can be with
It realizes Multi-point supercharging and feeding, improves product quality, can also realize the high-pressure casting or multi-point mould casting of ultra-large type casting
It makes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of double formed punch injection structures of die casting machine as shown in Figure 1, including framed 4, mold core 5, sprue bush 6.The mould
Core 5, which is inlayed, to be fixed in described framed 4；The sprue bush 6 is then embedded on the mold core 5, and 6 quantity of sprue bush is more
It is a, in the present embodiment there are two the settings of sprue bush 6.There are two be connected to the sprue bush 6 one-to-one correspondence for connection on described framed 4
Pressure chamber 2, and jumper bar 1 axially movable is provided in each pressure chamber 2.It is additionally provided with one more and pours in the top of the pressure chamber 2
The molten cup 3 of mouth, and more cast gates melt and multiple flow-guiding mouths are arranged on cup 3, and multiple flow-guiding mouth respectively corresponds multiple pressure chambers 2
Feed inlet.The jumper bar 1 is connected with nitrogen propulsion system, pushes the jumper bar 1 by the pressure nitrogen gas in nitrogen gas tank.Two institutes
It states jumper bar 1 and provides power by same nitrogen gas tank, and guarantee that two jumper bars 1 are run simultaneously.
When for multi-point mould casting, there are multiple type chambers, and described in the corresponding connection one of each type chamber on the mold core 5
Sprue bush 6 solves one-shot head injection, because of the problem of the filling distance is too long, the pressure loss is unable to complete greatly die casting.
When for heavy castings die casting, there is a type chamber on the mold core 5, and be set on mold core 5 multiple described pours
Muzzle 6 is connected to the type chamber on the mold core 5, from the injection simultaneously of multiple positions, Multi-point supercharging and feeding may be implemented, improve
Product quality.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
