Description

Technical Field

[0001] The invention relates to the technical field of automobile parts casting, in particular to a new energy automobile parts casting device. Background Art

[0002] New energy vehicles, including pure electric vehicles and hybrid vehicles, have key indicators such as performance, safety and mileage that are closely related to the quality of parts and components. Parts casting, as one of the basic processes in automobile manufacturing, is crucial to ensuring the overall performance and quality of new energy vehicles. Through the casting process, various parts with complex shapes, high precision requirements and superior performance can be produced, such as engine cylinders, gearbox housings, battery boxes, etc., to meet the design and manufacturing needs of new energy vehicles; First, the selected aluminum alloy material is melted. When the molten aluminum alloy is fed into the die-casting machine's pressure chamber and reaches the set temperature and pressure, the die-casting machine will start to close the mold and inject the molten metal into the mold cavity at high speed and high pressure. During this process, the molten metal quickly fills the cavity and cools and solidifies to form a casting with the required shape and size. After the molten metal solidifies into a solid state in the mold, it needs to be cooled. After the casting is taken out of the mold, it needs to be cleaned and trimmed. Finally, the casting is inspected and accepted to ensure that its quality meets the design requirements; however, during the die-casting process, The aluminum alloy solution will contact the inner wall of the pouring cup when entering the pressure chamber. When the temperature of the aluminum liquid is too high, the reaction between its surface and the oxygen in the air will be accelerated, forming an uneven adhesion layer on the inner wall of the pouring cup. These adhesion layers may be affected by the metal flow during the casting process and form attachments. As the number of pouring times increases, these attachments adhering to the inner wall of the pouring cup are likely to enter the pressure chamber of the die-casting machine along with the aluminum alloy solution, which can easily lead to the formation of pores and inclusions in the casting. These defects will directly affect the mechanical properties and durability of the casting. For this reason, we propose a new energy vehicle parts casting equipment. Summary of the invention

The inside of the material end, and the die casting frame 2 is also fixedly mounted with a mounting bracket 11, and a spray part 111 for outputting the cleaning agent is fixedly mounted on the top of the mounting bracket 11, and the spray part 111 is located on the motion trajectory of the pouring cup 8. It should be noted that at least three pipes are also installed on the mounting bracket 11, one of which is connected to the spray part 111, and the remaining two pipes are respectively used to transport pure water and to collect pure water. The number of connecting frames 71 in the present invention is at least two, and the number of pouring cups 8 is also at least two. Figure 3-5 As shown, one of the pouring cups 8 is located inside the feed end of the pressure chamber 3, and the other pouring cup 8 is located on the mounting bracket 11, and at this time the spraying part 111 is located inside the pouring cup 8. If there are attachments on the inner wall of the pouring cup 8, and the attachments have strong adhesion, the corresponding cleaning agent can be sprayed into the pouring cup 8 through the spraying part 111, and the cleaning agent must be a cleaning agent specially used for treating aluminum alloy oxide attachments. After treating the attachments, it can be cleaned by delivering pure water; The bottom of the mounting sleeve 7 is a magnetic surface, and an electromagnetic assembly 9 fixedly mounted on the outer wall of the pressure chamber 3 is arranged below the bottom of the mounting sleeve 7, and the electromagnetic assembly 9 generates a repulsive force on the magnetic surface of the mounting sleeve 7 when it is energized, and a plurality of telescopic shafts 72 are fixedly mounted on the inner wall of the mounting sleeve 7, and a plurality of lifting grooves 61 are arranged on the outer wall of the fixed shaft 6, and the lifting grooves 61 are connected through spiral grooves 62, and there is a height difference between the two ends of the spiral grooves 62, and a guide panel 63 with an inclined surface on one side and a right-angle surface on the other side is fixedly mounted at the intersection of the lifting grooves 61 and the spiral grooves 62, and the telescopic shafts 72 can slide within the lifting grooves 61 and the spiral grooves 62. Figure 5As shown, the guide panel 63 is installed at the intersection of the spiral groove body 62 (the relatively lower end) and the lifting groove body 61. The side of the guide panel 63 located at the lifting groove body 61 is an inclined surface, and the side located at the intersection of the lifting groove body 61 and the spiral groove body 62 is a right-angled surface. The fixed shaft body 6 is equipped with an annular frame 12 that is slidably connected to its outer wall, and the annular frame 12 is rotatably connected to the top of the mounting sleeve 7. A limit plate frame 14 is also fixedly installed near the top area of ​​the fixed shaft body 6, and a return spring 15 is connected between the limit plate frame 14 and the top of the annular frame 12. The annular frame 12 is also Two electromagnet bodies 121 are fixedly installed, one of which is located just above the feed end of the pressure chamber 3, and the other is located just above the ejection portion 111, and an arc magnet 122 is also fixedly installed on the annular frame 12, and the arc magnet 122 is located just above the mounting bracket 11. It should be noted that the direction of the current energized by the two electromagnet bodies 121 in the present invention can be changed. Changing the direction of the current can effectively change the magnetic poles of the electromagnet body 121. When the direction of the current is reversed, the magnetic poles of the electromagnet will also be swapped accordingly. In the initial state, the telescopic shaft 72 on the inner wall of the mounting sleeve 7 is located at the lowest end of the lifting trough 61. At this time, one of the pouring cups 8 is located inside the feed end of the pressure chamber 3, and the other pouring cup 8 is in contact with the top of the mounting bracket 11. When the electromagnetic component 9 is energized, the magnetic surface at the bottom of the mounting sleeve 7 will be subjected to the repulsive force of the electromagnetic component 9, and then the mounting sleeve 7 will drive the annular frame 12 to perform synchronous upward movement, and the annular frame 12 will squeeze the reset spring 15 during the rising process, and then the reset spring 15 is in a compressed state, and the telescopic shaft 72 on the inner wall of the mounting sleeve 7 will rise along the trajectory of the lifting trough 61. At the same time, the fixed frame 73 will drive the pouring cup 8 to perform synchronous upward movement. When the telescopic shaft 72 moves to the guide panel 63, the pouring cup 8 initially located inside the feed end of the pressure chamber 3 will move to above the feed end of the pressure chamber 3, and the pouring cup 8 on the mounting bracket 11 will also move above it. The telescopic shaft 72 moves to the right angle of the guide panel 63 When the cam 72 is in the upward direction, it will be guided by the right-angled surface of the guide panel 63, and then the telescopic shaft body 72 will continue to move and will enter the spiral groove body 62, and move along the trajectory of the spiral groove body 62, so that the installation sleeve 7 will rotate, and then the fixed frame body 73 and the pouring cup 8 thereon will rotate. If there are only two pouring cups 8, the pouring cup 8 initially located inside the feeding end of the pressure chamber 3 is located and moves to the top of the installation bracket 11, and the pouring cup 8 initially in contact with the installation bracket 11 will move to the top of the feeding end of the pressure chamber 3. When the telescopic shaft body 72 continues to move upward, it will move along the trajectory of the spiral groove body 62 to the top of the lifting groove body 61. If the electromagnetic component 9 is powered off, the annular frame 12 will drive the installation sleeve 7 to move downward under the action of the reset spring 15. At this time, the telescopic shaft body 72 will move downward along the trajectory of the lifting groove body 61. During the descent, the telescopic shaft body 72 will pass through the inclined surface of the guide panel 63 and continue to move along the trajectory of the lifting groove body 61 to return to the initial position. Furthermore, a plurality of fixed frames 73 are fixedly mounted on the mounting sleeve 7, and the fixed frames 73 correspond to the pouring cups 8 one by one, that is, each pouring cup 8 corresponds to a fixed frame 73, and a limiting shaft 74 rotatably connected to the inner wall thereof is also mounted on the fixed frame 73, wherein the limiting shaft 74 is symmetrically mounted with a movable frame 75 slidably connected to the outer wall thereof, and a magnetic shaft 76 is fixedly mounted on the end of each movable frame 75, wherein a flexible scraper 77 is fixedly mounted on the end of one of the magnetic shafts 76, and a detection portion 10 is provided on the end of the other magnetic shaft 76, and during the descent of the flexible scraper 77, its outer wall may contact the inner wall of the pouring cup 8; as a further limitation in the present invention, the detection portion 10 includes a magnetic shaft 76 fixedly mounted on the end of the magnetic shaft 76. The annular frame 101 is connected to the annular frame 101, and a plurality of limit seats 102 are fixedly installed on the outer wall of the annular frame 101. A detection shaft 103 rotatably connected to the inner wall thereof is installed between each limit seat 102. A rolling ball 104 rollingly connected to the inner wall thereof is installed at one end of the detection shaft 103. If the detection shaft 103 is located in the pouring cup 8, the rolling ball 104 will contact the inner wall of the pouring cup 8. A sensing element 105 is also fixedly installed inside the annular frame 101. The sensing element 105 is located on the motion trajectory of the detection shaft 103 away from the rolling ball 104. There is a certain friction between the movable frame 75 and the limit shaft 74. In the absence of external force, the movable frame 75 can be in a fixed state on the limit shaft 74. A driving shaft 13 slidably connected to the inner wall of the limiting shaft 74 is installed on the top of the limiting shaft 74, and a constant force spring 131 is connected between one end of the driving shaft 13 and the inner wall of the limiting shaft 74, and a connecting sleeve 731 is fixedly installed on the fixed frame 73, the driving shaft 13 is located inside the connecting sleeve 731, and the other end of the driving shaft 13 passes through the inner wall of the top of the connecting sleeve 731 and extends to the outside, the end of the driving shaft 13 located outside the connecting sleeve 731 is the magnetic end, and the arc magnet 122 is located on the movement trajectory of the driving shaft 13, and the arc magnet 122 has the same magnetic pole as the magnetic end of the driving shaft 13.

[0019] Specifically, the staff pours the molten aluminum alloy solution into the pouring cup 8 (the pouring cup 8 is the pouring cup 8 connected to the feed end of the pressure chamber 3) to enter the pressure chamber 3, and then the hydraulic cylinder 4 controls the punch 5 to act on the aluminum alloy solution, and the aluminum alloy solution is injected into the mold cavity at high speed and high pressure. The annular frame 101 is located directly above the feed end of the pressure chamber 3, and the flexible scraper 77 is located directly above the injection portion 111. Before the next molten aluminum alloy solution enters the pressure chamber 3, the electromagnet body 121 located directly above the feed end of the pressure chamber 3 is energized. Under normal energization conditions, the electromagnet body 121 will generate a repulsive force on the magnetic shaft 76, and then the magnetic shaft 76 is subjected to the repulsive force to move downward, and then the movable frame 75 slides on the limit position of the limit shaft 74. When the detection shaft 103 is located inside the pouring cup 8, the rolling ball 104 at the end of the detection shaft 103 will contact the inner wall of the pouring cup 8 (the rolling ball 104 is preferably a steel ball). When there is an attachment on the inner wall of the pouring cup 8, the rolling ball 104 will be affected by the attachment to cause the detection shaft 103 to rotate, and then the end of the detection shaft 103 away from the rolling ball 104 will contact the sensing element 105, and the sensing element 105 will send information to the terminal of the die-casting equipment 1, so that the current direction of the above-mentioned electromagnet body 121 is adjusted, and then the electromagnet body 121 will generate an attractive force on the magnetic shaft 76, so that the annular frame 101 and the mechanical parts inside it return to the initial position; Subsequently, the electromagnetic component 9 is energized, and the magnetic surface at the bottom of the mounting sleeve 7 will be subjected to the repulsive force of the electromagnetic component 9, and then the mounting sleeve 7 will drive the annular frame 12 to perform a synchronous upward movement, and the annular frame 12 will squeeze the return spring 15 during the upward process, and the telescopic shaft 72 on the inner wall of the mounting sleeve 7 will perform an upward movement along the trajectory of the lifting groove 61. At the same time, the fixed frame 73 will drive the pouring cup 8 to perform a synchronous upward movement, and the pouring cup 8 located inside the feeding end of the pressure chamber 3 will leave the feeding end of the pressure chamber 3. When the telescopic shaft 72 moves to the guide panel 63, it will be guided by the guide panel 63, and then the telescopic shaft 72 enters the spiral groove 62, and the mounting sleeve 7 rotates under the action of the spiral groove 62, and then the initial The pouring cup 8 initially located inside the feed end of the pressure chamber 3 is located above the mounting bracket 11, and the pouring cup 8 initially in contact with the mounting bracket 11 will move to above the feed end of the pressure chamber 3. When the telescopic shaft 72 enters the lifting tank 61, the electromagnetic component 9 breaks, and the annular frame 12 drives the mounting sleeve 7 to move downward under the action of the reset spring 15, and then the telescopic shaft 72 will continue to move along the trajectory of the lifting tank 61 through the inclined surface of the guide panel 63, so that one of the replaced pouring cups 8 enters the feed end of the pressure chamber 3, and the other contacts the surface of the mounting bracket 11, thereby realizing the replacement of the pouring cup 8. On the one hand, it will not affect the die-casting work, and on the other hand, it will prevent attachments from entering the pressure chamber 3 to cause pores and inclusions in the casting. When the angle adjustment of the installation sleeve 7 is completed, the fixed frame 73 initially located above the feed end of the pressure chamber 3 will move to the position directly below the arc-shaped magnet 122, and then the limit shaft 74 on the fixed frame 73 will also be located directly below the arc-shaped magnet 122, that is, the magnetic end of the drive shaft 13 located outside the connecting sleeve 731 will be located directly below the arc-shaped magnet 122. Since the arc-shaped magnet 122 has the same magnetic pole as the magnetic end of the drive shaft 13, the drive shaft 13 will be affected by the arc-shaped magnet 122. Due to the repulsive force of the magnet 122, the drive shaft 13 is subjected to the repulsive force of the arc-shaped magnet 122 to move downward, and then the annular shaft 132 on the outer wall of the drive shaft 13 moves along the trajectory of the arc-shaped groove 732, that is, the drive shaft 13 drives the limiting shaft 74 to rotate (the drive shaft 13 is slidably connected with the inner wall of the limiting shaft 74). When the drive shaft 13 moves along the trajectory of the arc-shaped groove 732, the constant force spring 131 is compressed. The limiting shaft 74 drives the movable frame 75 thereon to rotate synchronously. It should be noted that in the present invention, the rotation angle of the limiting shaft 74 is 180°. In the initial state, the flexible scraper 77 is closer to the fixed shaft 6 than the annular frame 101. When the angle of the limiting shaft 74 is adjusted, the annular frame 101 is closer to the fixed shaft 6 than the flexible scraper 77. Subsequently, the pipeline connected to the injection portion 111 introduces the cleaning agent into the injection portion 111, and then the injection portion 111 injects the cleaning agent into the pouring cup 8 in contact with the surface of the mounting bracket 11. After the cleaning agent is in contact with the attachment for a period of time, the electromagnet body 121 located directly above the injection portion 111 is energized to generate a repulsive force on the magnetic shaft 76, and the movable frame 75 descends along the outer wall of the limiting shaft 74, and the flexible scraper 77 scrapes and cleans the attachment on the inner wall of the pouring cup 8 and drops it onto the mounting bracket 11 (a groove is provided on the mounting bracket 11, as shown in the attached Fig.11 As shown), after scraping, pure water is introduced through a pipe to clean the inner wall of the pouring cup 8 and the flexible scraper 77, and then the current direction of the electromagnet body 121 (located directly above the injection portion 111) is adjusted, and the electromagnet body 121 will generate an attractive force on the magnetic shaft 76, so that the flexible scraper 77 returns to the initial position. When the mounting sleeve 7 rotates again, the driving shaft 13 will leave the bottom of the arc-shaped magnetic plate, and the driving shaft 13 will move to the initial position under the action of the constant force spring 131, and the limiting shaft 74 will rotate in the opposite direction, so that the flexible scraper 77 and the annular frame 101 both return to the above-mentioned initial position. Therefore, through the structural design of the present invention, the attachments on the inner wall of the pouring cup 8 can be effectively cleaned, and the attachments can be prevented from entering the pressure chamber 3 to cause pores and inclusions in the casting.
