Disclosure of Invention
The utility model relates to a die cavity structure of outer quick-witted box die casting die soon changes the order that aluminium liquid got into the die cavity through the quantity that increases the runner and improvement runner structure, and the die cavity of die casting die is difficult to be filled before solving, and some problems of gas pocket, cold line appear.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a mould cavity structure of outer quick-witted box die casting die soon, includes mold core, lower mold core to and go up the mold cavity that forms between mold core and the lower mold core, one side of going up the mold core is provided with the reposition of redundant personnel awl, and the lower part of this reposition of redundant personnel awl communicates the sprue, the one end bifurcation of sprue has arranged vice runner and is located the supplementary runner between the side runner, the side runner links to each other with the ladder runner of mold cavity both sides respectively, every step ladder portion of ladder runner all is provided with the subdivision runner, and the supplementary runner all communicates inside the mold cavity with the subdivision runner.
Furthermore, the subdivided runner and the supplementary runner are connected into the cavity through a gate, the thickness of the cross section of the gate is continuously reduced, the width of the gate is continuously increased, and the cross section area from the inlet of the gate to the connection part of the cavity is kept unchanged.
Furthermore, the width of the stepped flow channel is gradually reduced along with the steps.
Further, each step portion of the stepped flow passage is provided with an arc-shaped guide surface toward the outer side wall.
Has the advantages that: the utility model relates to a revolve outer quick-witted box die casting die's die cavity structure, increase the quantity of runner and improve the runner structure, through improving into the runner of echelonment with original ordinary runner, make the time of a plurality of runner feeds keep unanimous basically, reduced the die cavity and filled not full condition and appeared to the emergence of cold shut has been reduced.

The figure is as follows: 1. an upper mold core; 2. a lower mold core; 3. a cavity; 4. a spreader cone; 5. a main flow channel; 6. a secondary flow passage; 7. a supplementary flow channel; 8. a stepped flow channel; 9. a step portion; 10. subdividing a flow channel; 11. a circular arc-shaped guide surface; 12. and a gate.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-4, the utility model discloses an embodiment relates to a die cavity structure of outer quick-witted box die casting die soon, including last mold core 1, lower mold core 2 to and go up mold core 1 and the die cavity 3 that forms down between the mold core 2, one side of going up mold core 1 is provided with spreader 4, and the lower part of this spreader 4 communicates sprue 5, sprue 6 and the supplementary runner 7 that is located between sprue 6 are arranged to the one end branch of sprue 5, sprue 6 links to each other with the ladder runner 8 of die cavity 3 both sides respectively, 8 every step portions 9 of ladder runner all are provided with segmentation runner 10, and supplementary runner 7 all communicates inside the die cavity 3 with segmentation runner 10.
The subdivided runners 10 and the supplementary runners 7 are connected into the cavity 3 through the pouring gate 12, the thickness of the section of the pouring gate 12 is continuously reduced, the width of the pouring gate 12 is continuously increased, and the sectional areas from the inlet of the pouring gate 12 to the joint of the cavity 3 are kept unchanged, the pouring gate 12 can enable molten aluminum to enter the cavity 3 from the pouring gate 12 to increase the resistance, so that the flow direction resistance of the molten aluminum is small, the sequence of the molten aluminum entering the cavity is changed, the arrival time of the molten aluminum at the positions of the subdivided runners 10 is basically consistent, the temperature of the molten aluminum entering the subdivided runner 10 far away from the main runner 5 is ensured to be consistent with that of the molten aluminum close to the main runner 5 as much as possible, the occurrence of cold insulation of products is reduced, the gas trapping at the position of the pouring gate 12 due to the change of the sectional areas is avoided, the molten.
In order to better keep the time for the aluminum liquid to reach each subdivided flow passage 10 to be basically consistent, the width of the stepped flow passage 8 is gradually reduced along with the steps, so that the speed of the aluminum liquid to the next stepped flow passage 8 is increased, the subdivided flow passages 10 far away from the main flow passage 5 can also reach the aluminum liquid quickly, and the temperature of the aluminum liquid is kept.
In order to guide the molten aluminum to minimize the occurrence of entrainment, each step 9 of the stepped flow path 8 is provided with an arc-shaped guide surface 11 toward the outer side wall.
As the utility model discloses a use: the aluminum liquid enters the main runner 5 through the splitter cone 4 and is dispersed to the auxiliary runner 6 and the supplement runner 7, the flow speed of the aluminum liquid is slowed down due to the increased resistance at the sprue 12 of the supplement runner 7, meanwhile, the aluminum liquid smoothly enters the stepped runner 8 and reaches the subdivision runner 10 behind the stepped runner because the aluminum liquid is not limited when passing through the auxiliary runner 6, and then enters the cavity 3 through the subdivision runner 10 and the supplement runner 7 at the same time.
The utility model discloses increase the quantity of runner and improve the order that the runner structure gets into the die cavity through changing aluminium liquid to improve into the runner of echelonment with original ordinary runner, make the time of a plurality of runner feeds keep unanimous basically, reduced the condition appearance that the die cavity is not full, and reduced the emergence of cold shut.
