Abstract
The utility model discloses a pouring system which comprises at least one sprue and at least one cavity, wherein the upper end of the sprue is open, a collection cavity communicated with the sprue is formed at the lower end of the sprue, and the sprue is communicated with the cavity. In the pouring system disclosed by the utility model, the collection cavity communicated with the sprue is formed at the lower end of the sprue, the temperature of a small amount of molten metal firstly entering the sprue drops the most quickly, and the molten metal flows to the bottom of the sprue firstly; the collection cavity at the lower end of the sprue can collect the molten metal with the lowest temperature so that the temperature of the molten metal in the sprue tends to consistency, the problem of great difference between castings can be prevented, and the segregation reject ratio of products is reduced.
Description
Technical field
The utility model relates to a kind of system for casting and pouring, particularly a kind of running gate system.
Background technology
On market in existing running gate system, the a handful of molten metal temperature that enter the earliest sprue decline the most soon, also be the bottommost that flows into the earliest sprue, inconsistent in the molten metal temperature of sprue upper and lower like this, easily cause the Microstructure and properties of the product in sprue upper and lower inconsistent, easily there is segregation phenomena in the product in sprue bottom, thereby causes portioned product moulding bad.
Utility model content
The purpose of this utility model is to provide a kind of running gate system.
According to an aspect of the present utility model, a kind of running gate system is provided, comprise at least one sprue and at least one die cavity, the upper end open of sprue, lower end is provided with the collecting chamber being communicated with sprue, and sprue is communicated with die cavity.
In the utility model, sprue lower end is provided with the collecting chamber being communicated with sprue, the a handful of molten metal temperature that enter the earliest sprue decline the most soon, also be the bottommost that flows into the earliest sprue, the collecting chamber of sprue lower end can be collected the molten metal that this part temperature is minimum, thereby the molten metal temperature in sprue is reached unanimity, can prevent the large problem of differentiation between foundry goods, reduce the segregation fraction defective of product.
In some embodiments, can also comprise cup and cross gate, cup is communicated with cross gate, and the upper end of sprue is communicated with cross gate.Thus, molten metal injects from cup, and molten metal flow in sprue through cross gate.
In some embodiments, the quantity of sprue can be four, four parallel arranging of sprue.Thus, can four the parallel cast of sprues, improve cast efficiency.
In some embodiments, each sprue can be communicated with ten die cavities, and ten die cavities are arranged in the both sides of sprue symmetrically.Thus, each sprue can ten foundry goods of while moulding by casting.
In some embodiments, the radial section of die cavity can be ringwise.Thus, running gate system can moulding by casting annular element, as piston etc.
Accompanying drawing explanation
Fig. 1 is the structural representation of the running gate system of a kind of embodiment of the utility model;
Fig. 2 is that the running gate system shown in Fig. 1 is along the cross-sectional schematic of A-A line;
Fig. 3 is that the running gate system shown in Fig. 1 is along the cross-sectional schematic of B-B line.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 to Fig. 3 has schematically shown the structure of the running gate system of a kind of embodiment of the utility model.
As shown in Figure 1 to Figure 3, running gate system, comprises sprue 1 and die cavity 2.In addition, running gate system can also comprise cup 3 and cross gate 4.
In the present embodiment, the quantity of sprue 1 is four, four parallel arranging of sprue 1.In other embodiments, the quantity of sprue 1 can be also other number.
The bottom of each sprue 1 forms collecting chamber 11 (as shown in Figure 3), and collecting chamber 11 is communicated with the bottom of sprue 1.Collecting chamber 11 can be collected a handful of molten metals that enter the earliest sprue 1, thereby the molten metal temperature in sprue 1 is reached unanimity, and prevents the large problem of differentiation between foundry goods, reduces the segregation fraction defective of product.
In the present embodiment, each sprue 1 is communicated with ten die cavities 2, and ten die cavities 2 are arranged in the both sides of sprue 1 symmetrically.In other embodiments, each sprue 1 also can be communicated with the die cavity 2 of other number.
The both sides of each sprue 1 form five pairs of runners 12 (as shown in Figure 2), and each sprue 1 is communicated with ten die cavities 2 by runner 12.
In the present embodiment, the radial section of die cavity 2 is shape ringwise, and moulding by casting annular element, as piston etc.In other embodiments, die cavity 2 can change according to the shape of required pouring piece.
Cup 3 is communicated with cross gate 4.
The top of each sprue 1 is communicated with cross gate 4.
Molten metal is poured in cross gate 4 by cup 3, then molten metal is diverted in four sprues 1, the a handful of molten metal temperature that enter the earliest sprue 1 decline the most soon, also be the bottommost that flows into the earliest sprue 1, the collecting chamber 11 of sprue 1 bottom is collected the minimum molten metal of this part temperature, molten metal in each sprue 1 flow in each die cavity 2 by runner 12, and then moulding, because collecting chamber 11 has been collected the minimum molten metal of temperature that enters the earliest sprue 1, thereby the molten metal temperature in sprue 1 is reached unanimity, prevented the large problem of differentiation between profiled member, reduce the segregation fraction defective of product.
Above-described is only a kind of embodiment of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
