Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of aluminum alloy structural part production, and particularly relates to a die-casting forming device for aluminum alloy structural part machining. BACKGROUND

[0002] The die-casting forming process has become a core technical path for industrialized production of aluminum alloy structural parts due to the advantages of high production efficiency, good forming precision and batch preparation of complex structural parts. However, in actual production, the high viscosity characteristics of aluminum alloy casting melt restrict the die-casting effect, and the viscosity is much higher than that of common casting materials such as steel, so the flowability is very poor at the conventional die-casting temperature, which leads to a significant increase in resistance when the melt fills the mold cavity.

[0003] Especially for molds with complex internal cavities, thin-walled structures or small holes, the high-viscosity melt is difficult to fully fill the cavity, and is prone to form forming defects such as material shortage and cold separation in the local structure, which destroys the appearance integrity and structural continuity. At the same time, the poor flow of the melt also causes the air inside the cavity to be unable to be discharged in time, and a large number of air bubbles are formed inside the structure due to the residual air, which seriously weakens the internal compactness and greatly reduces the product quality.

[0004] To accelerate the solidification forming of aluminum alloy liquid, the existing equipment often lays water cooling pipes in the fixed mold, and cools through circulating cooling water. However, the water cooling pipes are directly embedded in the mold body of the fixed mold, and lack effective heat insulation or temperature control buffer structures. In the initial stage of injection of the aluminum alloy liquid into the forming cavity, the residual or circulating cooling water in the pipes will directly exchange heat with the mold body, causing the mold body temperature to drop rapidly. After the high-temperature aluminum alloy liquid contacts the low-temperature mold body, the temperature of the aluminum alloy liquid drops rapidly, the viscosity rises sharply, and the flowability deteriorates dramatically, which further aggravates the incomplete filling problem, and the forming parts still frequently appear defects such as material shortage, cold separation and air bubbles, the quality stability is insufficient, and the product quality consistency cannot meet the requirements of industrialized batch production.

[0026] Reference Figures 1-5 In the present embodiment, the present embodiment provides a die casting forming device for aluminum alloy structural part machining, which comprises a fixed mold 1, a movable mold 3, a plurality of injection pistons 7 and a vibrating ball 8. The fixed mold 1 is provided with an air passage 2 and a first mold cavity 4. The movable mold 3 is configured to be lifted above the fixed mold 1. The movable mold 3 is provided with a feeding pipe 5 and a pressurizing pipe 6. The pressurizing pipe 6 is located directly above the air passage 2. The plurality of injection pistons 7 are configured to be synchronously slidably arranged in the feeding pipe 5 and the pressurizing pipe 6. The injection pistons 7 are used to pressurize the gas inside the feeding pipe 5 and the pressurizing pipe 6. It can be understood that the injection pistons 7 are currently driven by an injection mechanism. The injection mechanism is a prior art. The specific injection mechanism can be a hydraulic drive type injection mechanism or a mechanical drive type injection mechanism. The vibrating ball 8 is located at the bottom of the first mold cavity 4 and is configured to be knocked and vibrated by the sliding injection pistons 7 to pressurize the first mold cavity 4, thereby improving the fluidity of the aluminum alloy melt in the first mold cavity 4 and eliminating the air bubbles in the aluminum alloy melt. The fixed mold 1 and the movable mold 3 are both provided with a cooling cavity 9 and a plugging cavity 11. The cooling cavity 9 is provided with a water inlet 10. The plugging cavity 11 is in communication with the cooling cavity 9 through the water inlet 10. The plugging cavity 11 is provided with a water inlet. A plugging plate 12 is slidably arranged in the plugging cavity 11. The plugging plate 12 is configured to slide relative to the water inlet in the plugging cavity 11 by the sliding pressurization linkage of the injection pistons 7, thereby controlling the communication state of the water inlet and the plugging cavity 11. In the present embodiment, the cooling cavity 9 is arranged outside the mold cavity, which is used to cool the aluminum alloy melt in the mold cavity. It should be noted that the first mold cavity 4 and the second mold cavity 33 are collectively referred to as the mold cavity.

[0027] Reference Figure 4 andFigure 5 In the embodiment, the vent passage 2 is arranged outside the first mold cavity 4, the movable mold 3 is provided with a second mold cavity 33, and the feeding pipe 5 is communicated with the second mold cavity 33. The side wall of the vent passage 2 and the side wall of the pressurizing pipe 6 are both provided with a communication hole 34. The blocking cavity 11 in the fixed mold 1 is communicated with the vent passage 2 through the communication hole 34, and the blocking cavity 11 in the movable mold 3 is communicated with the pressurizing pipe 6 through the communication hole 34. The water inlet pipe 13 is connected with the water inlet, and the water outlet is further arranged on the cooling cavity 9. The water outlet is connected with a water outlet pipe. The part of the water inlet pipe 13 and the water outlet pipe between the fixed mold 1 and the movable mold 3 is a folding bellows. The folding bellows is arranged to adapt to the lifting of the movable mold 3. The water outlet pipe is connected with a water pump 14. The water pump 14 and the water inlet pipe 13 are both connected with a cooling circulation machine. Since the cooling circulation machine is a prior art, it is not specifically shown in the scheme.

[0028] It can be understood that the feeding pipe 5 is a prior art. The feeding pipe 5 is provided with a feeding pipe. The aluminum alloy melt enters the feeding pipe 5 from the feeding pipe. The feeding pipe 5 is driven by the injection mechanism to move the injection piston 7. The injection piston 7 in the feeding pipe 5 pressurizes the aluminum alloy melt to make the aluminum alloy melt enter the mold cavity of the fixed mold 1 and the movable mold 3. In the embodiment, the lifting action of the movable mold 3 relative to the fixed mold 1 is achieved by a pneumatic cylinder.

[0029] In specific use, in the initial state, the blocking plate 12 blocks the water inlet to separate the blocking cavity 11, the cooling cavity 9 and the water inlet pipe 13. Under the action of the water pump 14, all the cooling liquid in the cooling cavity 9 is pumped out to avoid the remaining of the cooling liquid in the cooling cavity 9. The movable mold 3 is driven to fall to combine with the fixed mold 1 to form a complete mold. The aluminum alloy melt enters the feeding pipe 5 along the feeding pipe. Under the action of the injection mechanism, the injection piston 7 in the feeding pipe 5 and the pressurizing pipe 6 is driven. The injection piston 7 in the feeding pipe 5 pressurizes the aluminum alloy melt to assist the feeding of the aluminum alloy melt. The injection piston 7 in the pressurizing pipe 6 moves synchronously to continuously pressurize the gas in the pressurizing pipe 6 and the vent passage 2. Through the pressurized gas flow linkage, the vibrating ball 8 is driven to reciprocatingly lift and knock the first mold cavity 4 to make the first mold cavity 4 slightly vibrate to improve the flowability of the aluminum alloy melt and eliminate the bubbles in the aluminum alloy melt. While the injection piston 7 in the pressurizing pipe 6 moves downward to pressurize, the blocking plate 12 is driven to slide in the blocking cavity 11 through the pneumatic linkage to unblock the water inlet. After the aluminum alloy melt is completely filled into the mold cavity, the water pump 14 is started to pump the cooling liquid into the cooling cavity 9. Under the action of the water pump 14 and the cooling circulation machine, the circulation of the cooling liquid in the cooling cavity 9 is ensured to continuously cool the aluminum alloy structural member in the mold cavity. After the cooling is completed, the movable mold 3 is driven to rise to take out the aluminum alloy structural member.

[0030] Referring to Figure 2 and Figure 6In the embodiment, the impeller 15 is rotatably arranged in the fixed mold 1 and located directly below the air passage 2. The impeller 15 is driven to rotate in the fixed mold 1 by the pressurized airflow. The fixed mold 1 is provided with a communication passage 16. The reciprocating piston 17 is slidably arranged in the communication passage 16. The communication passage 16 ensures the stable reciprocating movement of the reciprocating piston 17. The shaft is provided with a disc 18. The disc 18 is hingedly provided with a connecting rod one 19. The reciprocating piston 17 is provided with a connecting rod two 20. The connecting rod one 19 and the connecting rod two 20 are hingedly connected.

[0031] In actual use, when the injection piston 7 slides downward, the continuous pressurized airflow acts on the impeller 15 to drive the impeller 15 to rotate. The shaft is driven to rotate by the impeller 15. The disc 18 is driven to rotate by the shaft. The rotating disc 18 drives one end of the connecting rod one 19 to rotate. The other end of the connecting rod one 19 pulls the connecting rod two 20 and the reciprocating piston 17 to reciprocate in the communication passage 16. The reciprocating piston 17 reciprocates in the communication passage 16 to suck the gas therein and drive the vibration ball 8 to reciprocate to knock the first mold cavity 4. When the injection piston 7 stops descending and pressurizing, the impeller 15 stops rotating because there is no longer a continuous pressurized airflow. The vibration ball 8 stops knocking and vibrating the first mold cavity 4. At this time, the aluminum alloy melt in the mold cavity is cooled and shaped under the action of the cooling liquid. In the above process, the knocking and vibrating action of the vibration ball 8 is completely matched with the time node of the downward sliding and pressurizing of the injection piston 7.

[0032] Referring to Figure 7 In the embodiment, two groups of discs 18 are symmetrically arranged at both ends of the shaft. The communication passage 16 and the reciprocating piston 17 are correspondingly arranged with the disc 18. The two groups of communication passages 16 are connected through the communication cavity 21.

[0033] Referring to Figure 2 In the embodiment, the fixed mold 1 is provided with a vibration cavity 22. The vibration cavity 22 is located above the communication cavity 21. The vibration cavity 22 is provided with a pushing assembly 23. The vibration ball 8 is connected with the pushing assembly 23.

[0034] Referring to Figure 4 and Figure 5 In the embodiment, the plugging cavity 11 is provided with a supporting plate 24. The supporting plate 24 is provided with a ventilation cavity 25. The ventilation cavity 25 is connected with the corresponding air passage 2 or the inner cavity of the pressurizing pipe 6 through the communication hole 34. The supporting plate 24 is provided with the pushing assembly 23. The plugging plate 12 is connected with the pushing assembly 23.

[0035] Referring to Figure 3In the embodiment, the pushing assembly 23 comprises a pushing sleeve 26, a pushing slide rod 27 and a pushing piston 28. The pushing sleeve 26 is fixedly arranged. The pushing piston 28 is driven by air pressure to slide in the pushing sleeve 26. The pushing slide rod 27 is connected with the pushing piston 28. The pushing slide rod 27 is sleeved with a reset spring 29. Two ends of the reset spring 29 are connected with the top wall of the pushing sleeve 26 and the pushing piston 28 respectively.

[0036] Referring to Figure 2 and Figure 3 In the embodiment, the pushing sleeve 26 in the vibration cavity 22 is arranged through the bottom wall of the vibration cavity 22 and communicates with the communicating air cavity 21.

[0037] Referring to Figure 4 and Figure 5 In the embodiment, the pushing sleeve 26 in the plugging cavity 11 is arranged through the support plate 24 and communicates with the air cavity 25.

[0038] In specific use, the injection piston 7 in the feeding pipe 5 slides downward to pressurize the aluminum alloy melt for feeding, and the injection piston 7 in the pressurizing pipe 6 pressurizes the gas in the pressurizing pipe 6 and the air passage 2. The continuous pressurized gas acts on the impeller 15, the impeller 15 drives the rotating shaft to rotate, and drives the reciprocating piston 17 to slide reciprocally in the communicating passage 16 to suck the gas in the vibration cavity 22. The sucked gas acts on the pushing piston 28 of the pushing assembly 23 in the vibration cavity 22 to drive the pushing piston 28 to reciprocally lift, and cooperates with the reset spring 29 to drive the vibration ball 8 to reciprocally lift stably. The reciprocally lifting vibration ball 8 knocks the first mold cavity 4 to improve the flow rate of the aluminum alloy melt and eliminate the bubbles. In the process, through the linkage between the pressurized gas flow and the plugging plate 12, the precise matching of the cooling opportunity and the pressurized liquid feeding is realized: in the initial state, the plugging plate 12 is driven by the pushing assembly 23 to plug the water inlet, and the cooling liquid in the cooling cavity 9 is completely sucked out by the water pump 14 to avoid the mold body and the cooling liquid to be in contact to cool down in advance. At this time, the mold cavity maintains the appropriate temperature to ensure that the aluminum alloy liquid maintains good fluidity to successfully complete the filling. After the aluminum alloy melt is completely filled into the mold cavity, the injection piston 7 drives the plugging plate 12 to slide to unplug the water inlet. The cooling liquid enters the cooling cavity 9 under the action of the water pump 14 and the cooling circulation machine to realize stable circulation heat exchange and accelerate the solidification of the structural part.

[0039] In the above process, the knocking of the vibration ball 8 is synchronized with the pressurized liquid filling of the aluminum alloy melt, and the first mold cavity 4 is knocked throughout the liquid filling process. No additional knocking mechanism of the vibration ball 8 is needed, and the knocking timing of the vibration ball 8 is completely matched with the pressurized liquid filling timing. In addition, the position of the blocking plate 12 is regulated at the same time of liquid filling. Through the position regulation of the blocking plate 12, the emptying demand of the cooling liquid in the cooling cavity 9 before the liquid filling of the aluminum alloy melt is met, and the circulating cooling demand of the cooling liquid in the cooling cavity 9 after the pressurized liquid filling is ensured. The three core actions of the driving of the injection piston 7, the linkage triggering of the vibration ball 8, and the synchronous control of the opening of the blocking plate 12 are cooperated with each other.

[0040] Referring to Figure 2 , Figure 7 and Figure 8 , in the embodiment, the plurality of groups of air passages 2 are arranged above the impeller 15. The upper ends of the air passages 2 of one group extend through the top wall of the fixed mold 1. The air passages 2 of the plurality of groups are communicated with each other. The impeller 15 is driven to stably rotate by cooperating with the pressurization of the plurality of points through the communicated air passages 2.

[0041] Referring to Figure 2 , Figure 6 and Figure 8 , in the embodiment, the cooling cavity 9 in the movable mold 3 is arranged at the four sides and the top of the second mold cavity 33. The feeding pipe 5 extends through the cooling cavity 9 of the movable mold 3 to the second mold cavity 33. The cooling cavity 9 in the fixed mold 1 is arranged at the four sides and the bottom of the first mold cavity 4. The bottom of the cooling cavity 9 of the fixed mold 1 includes a plurality of groups of cooling channels 30 arranged at intervals. The cooling channels 30 are arranged on the bottom wall of the first mold cavity 4. A plurality of groups of pushing assemblies 23 are arranged between the adjacent two groups of cooling channels 30. The vibration balls 8 are arranged one by one corresponding to the pushing assemblies 23.

[0042] In specific use, the cooling efficiency of the aluminum alloy melt in the mold cavity is improved through the surrounding arrangement of the cooling cavity 9 in the mold cavity. The stability of the vibration acceleration flow and the elimination of bubbles is ensured through the cooperation of the plurality of groups of pushing assemblies 23 and the vibration balls 8 for the multi-point vibration of the mold cavity of the fixed mold 1.

[0043] Referring to Figure 1 and Figure 6 , in the embodiment, one of the opposite sides of the fixed mold 1 and the movable mold 3 is provided with a sealing groove 31, and the other of the opposite sides is provided with a sealing protrusion 32. The sealing protrusion 32 corresponds to the sealing groove 31. The accuracy and the sealing property of the assembly and positioning of the fixed mold 1 and the movable mold 3 are ensured through the cooperation of the sealing protrusion 32 and the sealing groove 31.
