Description

Technical Field

[0001] This invention relates to the field of die casting technology, specifically to a die casting equipment and die casting method for aluminum alloy housing die casting parts. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal within a mold cavity. The mold is typically made of a high-strength alloy, and the process is somewhat similar to injection molding. Most die-cast parts are iron-free, containing materials such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Due to the high cost of casting equipment and molds, die casting is generally used only for mass production of large quantities of products. Die casting is particularly suitable for manufacturing large quantities of small to medium-sized castings, making it one of the most widely used casting processes. Compared to other casting techniques, die casting produces a smoother surface and greater dimensional consistency.

[0003] In existing technologies, aluminum alloy shells are mostly produced using die casting. Currently, the blanking of die-cast products is usually done by directly removing the product from the die-casting mold and letting it fall into the material tray. However, the die-cast part is not completely solidified; only the outer shell is solidified. Moreover, the workpiece temperature is high during demolding, and the impact surface is prone to dents when the workpiece falls. Since aluminum alloy shells are relatively thin, they are easily rendered unusable after impacts, resulting in a low yield rate. Increasing the heat dissipation time would reduce the production efficiency of aluminum alloy shells and would not completely prevent the problem of impact damage to the aluminum alloy shells. Summary of the Invention

[0004] The purpose of this invention is to provide a die-casting equipment and die-casting method for aluminum alloy housing die-casting parts, in order to solve the problem mentioned in the background art that the production of aluminum alloy housings is mostly carried out by die casting. Currently, the blanking of die-cast products is mostly done by directly removing the product from the die-casting mold and letting it fall into the material tray. However, the die-cast part is not completely solidified, only the outer shell is solidified. Moreover, the workpiece temperature is high when demolding, and the impact surface is prone to dents when the workpiece falls. Since the aluminum alloy housing is relatively thin, the aluminum alloy housing is easily rendered unusable after an impact, resulting in a low yield rate. Increasing the heat dissipation time will reduce the production efficiency of aluminum alloy housings on the one hand, and on the other hand, it cannot completely avoid the problem of impact damage to the aluminum alloy housing.

[0007] Preferably, a round rod groove is provided on one side of the lower end of the end clamping plate and one side of the upper end of the bottom clamping plate. The round rod groove is rotatably connected to the middle rod. A limiting groove is provided on the other side of the lower end of the end clamping plate and the other side of the upper end of the bottom clamping plate. The limiting groove is engaged with the end of the No. 3 hydraulic cylinder.

[0008] Preferably, a side mounting groove is provided on the other side of the stop plate, a slot is provided on one side of the side mounting groove, the side plate is located in the side mounting groove, and an insert plate is fixedly connected to one side of the side plate, the insert plate being inserted into the slot.

[0009] Preferably, a connecting box is fixedly connected to both sides of the middle part of the upper side of the bottom support frame, and a second connecting port is fixedly connected to one side of the connecting box. The two second connecting ports are used to connect to the output end of the air pump through pipes. An air outlet is opened on one side of the connecting box. The air outlet is designed with an inclination, and the inclination direction of the air outlet is parallel to the inclination direction of the inclined plate. A side groove is opened in the middle of the corner of the bottom support frame.

[0010] Preferably, side baffles are provided on both sides of the upper end of the inclined plate, and limiting slide rails are fixedly connected to the middle of one side of each of the two side baffles. A first slide groove is opened on the inner side of the base frame, and the first slide groove is slidably connected to the side plate.

[0011] Preferably, an end frame is fixedly connected to the upper end of the base frame, a feeding mechanism is fixedly connected to one side of the end frame, a first mold and a second mold are installed inside the end frame, and a conveying pipe is installed between the feeding mechanism and the first mold.

[0012] Preferably, a guide rod is fixedly connected inside the end frame, the second mold is slidably connected to the guide rod, and protective plates are fixedly connected to both sides of the end frame.

[0013] Preferably, a driving mechanism is fixedly connected to one side of the end frame, and the driving mechanism is connected to the second mold in a transmission connection. A cooling mechanism is fixedly connected to one side of the base frame, and the cooling mechanism is used to cool down the first mold and the second mold.

[0014] A die-casting method for an aluminum alloy housing includes the following steps:

[0015] S1. Based on the thickness of the formed aluminum alloy shell, control the movement of hydraulic cylinder No. 3 and hydraulic cylinder No. 2 to adjust the distance between the side plate and the L-shaped connecting plate.

[0016] S2. The feeding mechanism injects the molten aluminum alloy liquid into the space between mold No. 1 and mold No. 2 through the feeding pipe. The cooling mechanism cools mold No. 1 and mold No. 2. Then the driving mechanism drives mold No. 2 to move, so that the formed aluminum alloy shell is exposed.

[0017] S3. The L-shaped connecting plate is pushed up by the No. 1 hydraulic cylinder, so that the upper end of the L-shaped connecting plate contacts the lower end of the No. 1 mold. The air pump is turned on, so that airflow enters through the through hole and airflow is ejected from the air outlet. The airflow caused by the through hole cools the aluminum alloy shell. Then the demolding component pushes out the aluminum alloy shell. When the aluminum alloy shell is fully exposed, its surface contacts the side plate. At this time, the aluminum alloy shell moves down by gravity and falls between the L-shaped connecting plate and the side plate. The through hole adsorbs and restricts the aluminum alloy shell.

[0018] S4. The first hydraulic cylinder retracts completely, so that the upper end of the stop plate is below the first mold. At this time, the drive mechanism drives the second mold to close with the first mold, and then injects the aluminum alloy molten liquid between the first mold and the second mold for die casting production again.

[0019] S5. The second hydraulic cylinder retracts, causing the stop plate to rotate. Due to the adsorption of the through hole, the aluminum alloy shell rotates together with the stop plate. When the stop plate is parallel to the inclined plate, the aluminum alloy shell moves and slides onto the surface of the inclined plate. The gas ejected from the air outlet cools the aluminum alloy shell on one hand and pushes the aluminum alloy shell to move on the other hand, causing the aluminum alloy shell to slide into the material tray.

[0020] S6. Pull out the material tray, remove the aluminum alloy shell, and then put the material tray back in.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the L-shaped connecting plate and side plate restrict the aluminum alloy shell during unloading. The airflow further slows the falling speed of the aluminum alloy shell, reducing impact and preventing collisions. Simultaneously, the airflow continues to cool the aluminum alloy shell, ensuring a high production yield. The inclined plate and hydraulic cylinder No. 2 work together to slowly move the aluminum alloy shell onto the placement tray, facilitating collection of the formed shells. This method avoids wear on the aluminum alloy shell, ensuring a high production yield.

[0023] 2. In this invention, the No. 3 hydraulic cylinder and the No. 2 hydraulic cylinder are used to push the stop plate to move, thereby adjusting the distance between the side plate and the L-shaped connecting plate to suit aluminum alloy shells of different thicknesses. Through the setting of the side plate and the insert plate, the side plate adopts a detachable design. During use, different side plates are selected according to the position of the protrusion of the aluminum alloy shell, so that the through hole can contact and cooperate with the protrusion of the aluminum alloy shell after the aluminum alloy shell falls into the L-shaped connecting plate, so as to improve the adsorption effect. Thus, when the aluminum alloy shell is rotated, it can prevent the aluminum alloy shell from shifting and falling during the rotation process, ensuring stability during use.

[0024] 3. In this invention, by setting up the connecting box, when the aluminum alloy shell is flipped over and the upper surface of the side plate is parallel to the upper surface of the inclined plate, the aluminum alloy shell can be moved by the flow of air and cooled at the same time. The side baffle is used to limit the movement area of ​​the aluminum alloy shell and ensure that the aluminum alloy shell can fall into the material tray. Attached Figure Description

[0037] Example 1: Refer to Figure 1 - Figure 8As shown: A die-casting equipment for aluminum alloy housing die-casting parts includes a die-casting mechanism 1. The die-casting mechanism 1 includes a base frame 11. A feeding mechanism 2 is installed inside the base frame 11. The feeding mechanism 2 includes a limiting frame 25 and a mounting frame 215.

A material placement tray 21 is slidably connected inside the limiting frame 25. An inclined plate 216 is fixedly connected to the upper end of the mounting frame 215. One end of the inclined plate 216 is fixedly connected to the upper end of the limiting frame 25. A base support frame 29 is fixedly connected to one side of the mounting bracket 215. An L-shaped connecting plate 28 is provided at the upper end of the base support frame 29. A first hydraulic cylinder 23 is fixedly connected to both sides of the middle part inside the base support frame 29. The upper end of the first hydraulic cylinder 23 is fixedly connected to the L-shaped connecting plate 28. A limiting groove 232 is opened at the lower end of the L-shaped connecting plate 28. A second sliding groove 212 is opened on both sides of the limiting groove 232. A stop plate 22 is provided inside the limiting groove 232. A connecting plate 22 is fixedly connected to the lower end of both sides of the stop plate 22. A slider 224 is rotatably connected to the outer surface of rod 225. Slider 224 restricts the movement direction of stop plate 22. Compared to direct connection between connecting rod 225 and second slide groove 212, this provides greater stability. Slider 224 is slidably connected to second slide groove 212. A second hydraulic cylinder 27 is rotatably connected to one side of stop plate 22. A connecting seat 221 is rotatably connected to the other end of hydraulic cylinder 27. The lower end of connecting seat 221 is fixedly connected to the ground. A fixed connection is also made to one side of stop plate 22. There is a first connection port 213, and an inner cavity 222 is opened on the other side of the stop plate 22. The first connection port 213 is connected to the inner cavity 222. A side plate 214 is provided on one side of the stop plate 22. A through hole 223 is opened on one side of the side plate 214. The first connection port 213 is used to connect to the input end of the air pump through a pipe. A port 26 is opened in the middle of the other end of the inclined plate 216. The air pump is placed inside the mounting bracket 215. The pipe connected to the first connection port 213 passes through the port 26 for connection.

[0038] In this invention, the L-shaped connecting plate 28 and the side plate 214 restrict the aluminum alloy shell during unloading. The airflow further slows the falling speed of the aluminum alloy shell, reducing impact and preventing collisions. Simultaneously, the airflow continues to cool the aluminum alloy shell, ensuring a high production yield. The inclined plate 216, in conjunction with the second hydraulic cylinder 27, slowly moves the aluminum alloy shell onto the placement tray 21, facilitating collection of the formed shells. This method avoids wear on the aluminum alloy shell, ensuring a high production yield.

The circular rod groove 228 is rotatably connected to the central rod 226. A limiting slot 229 is provided on the other side of the lower end of the end clamping plate 230 and the other side of the upper end of the bottom clamping plate 227 to limit... The slot 229 engages with the end of the third hydraulic cylinder 210. The other side of the stop plate 22 is provided with a side mounting groove 234. A slot 233 is provided on one side of the side mounting groove 234. The side plate 214 is located in the side mounting groove 234. A plug plate 231 is fixedly connected to one side of the side plate 214. The plug plate 231 is inserted into the slot 233. The end clamp plate 230 and the bottom clamp plate 227 are fixedly connected by screws and nuts. The bottom clamp plate 227 and the end clamp plate 230 adopt a split design, which facilitates the installation between the third hydraulic cylinder 210 and the stop plate 22.

[0040] In this invention, the No. 3 hydraulic cylinder 210 and the No. 2 hydraulic cylinder 27 are used to push the stop plate 22 to move, thereby adjusting the distance between the side plate 214 and the L-shaped connecting plate 28 to accommodate aluminum alloy shells of different thicknesses. The side plate 214 is designed to be detachable by the side plate 214 and the insert plate 231. During use, different side plates 214 are selected according to the position of the protrusion of the aluminum alloy shell, so that the through hole 223 can contact and cooperate with the protrusion of the aluminum alloy shell after the aluminum alloy shell falls into the L-shaped connecting plate 28, so as to improve the adsorption effect. This prevents the aluminum alloy shell from shifting and falling during rotation, ensuring stability during use.

[0041] Example 3: According to Figure 1 - Figure 6As shown, a connecting box 217 is fixedly connected to both sides of the middle part of one side of the upper end of the base support frame 29. A second connecting port 220 is fixedly connected to one side of the connecting box 217. The two second connecting ports 220 are used to connect to the output end of the air pump through pipes.

The air outlet 218 is designed with an inclination, and the inclination direction of the air outlet 218 is parallel to the inclination direction of the inclined plate 216. A side groove 219 is opened in the middle of the corner of the base support frame 29. Side baffles 24 are provided on both sides of the upper end of the inclined plate 216. A limiting slide rail 235 is fixedly connected to both sides of the middle part of one side of the two side baffles 24. A first slide groove 211 is opened on the inner side of the base frame 11. The first slide groove 211 is slidably connected to the side plate 214. An end frame 12 is fixedly connected to the upper end of the base frame 11. A feeding mechanism 13 is fixedly connected to one side of the end frame 12. The interior of mold 2 is equipped with mold 15 and mold 2. A feeding mechanism 13 is connected to mold 15 with a feeding pipe 14. A guide rod 17 is fixedly connected inside the end frame 12. Mold 2 is slidably connected to guide rod 17. Protective plates 110 are fixedly connected to both sides of the end frame 12. A drive mechanism 18 is fixedly connected to one side of the end frame 12. The drive mechanism 18 is connected to mold 2 with a transmission connection. A cooling mechanism 19 is fixedly connected to one side of the base frame 11. The cooling mechanism 19 is used to cool mold 15 and mold 2 with a cooling capacity. The connection box 217 and the first connection port 213 are driven by the same air pump. The connection between the second connection port 220 and the air pump is first made by connecting two pipes to the second connection port 220 respectively. Then, the two pipes are connected by a T-fitting pipe. Finally, the T-fitting pipe is connected to the output end of the air pump with a pipe.

[0042] In this invention, by setting the connecting box 217, when the aluminum alloy shell is flipped over and the upper surface of the side plate 214 is parallel to the upper surface of the inclined plate 216, the aluminum alloy shell can be moved by the flow of air and cooled at the same time. The side baffle 24 is used to limit the movement area of ​​the aluminum alloy shell and ensure that the aluminum alloy shell can fall into the material tray 21.

[0043] Example 4: A die-casting method for an aluminum alloy housing, comprising the following steps:

[0044] Step 1: Based on the thickness of the formed aluminum alloy shell, control the movement of hydraulic cylinder 210 and hydraulic cylinder 27 to adjust the distance between side plate 214 and L-shaped connecting plate 28.

[0045] Step 2: The feeding mechanism 13 injects the molten aluminum alloy liquid into the space between mold 15 and mold 2 through the feeding pipe 14. The cooling mechanism 19 cools mold 15 and mold 2. Then the driving mechanism 18 drives mold 2 to move, so that the formed aluminum alloy shell is exposed.

[0046] Step 3: The L-shaped connecting plate 28 is pushed up by the first hydraulic cylinder 23, so that the upper end of the L-shaped connecting plate 28 contacts the lower end of the first mold 15. The air pump is turned on, so that airflow enters through the through hole 223 and airflow is ejected from the air outlet 218. The airflow caused by the through hole 223 cools the aluminum alloy shell. Then the demolding component pushes out the aluminum alloy shell, so that when the aluminum alloy shell is fully exposed, the surface contacts the side plate 214. At this time, the aluminum alloy shell moves down by gravity and falls between the L-shaped connecting plate 28 and the side plate 214. The through hole 223 adsorbs and restricts the aluminum alloy shell.

[0047] Step 4: The first hydraulic cylinder 23 retracts completely, so that the upper end of the stop plate 22 is below the first mold 15. At this time, the drive mechanism 18 drives the second mold 16 to close with the first mold 15. Then, the molten aluminum alloy is injected between the first mold 15 and the second mold 16 for die casting production again.

[0048] Step 5: The second hydraulic cylinder 27 retracts, causing the stop plate 22 to rotate. Due to the adsorption of the through hole 223, the aluminum alloy shell rotates together with the stop plate 22. When the stop plate 22 is parallel to the inclined plate 216, the aluminum alloy shell moves and slides onto the surface of the inclined plate 216. The gas ejected from the air outlet 218 cools the aluminum alloy shell on one hand and pushes the aluminum alloy shell to move on the other hand, so that the aluminum alloy shell slides into the material tray 21.

[0049] Step 6: Pull out the material tray 21, remove the aluminum alloy shell, and then put the material tray 21 back in.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

7. A die-casting method for an aluminum alloy housing die-casting part, characterized in that: The die-casting equipment using the aluminum alloy housing die-casting part according to any one of claims 1-6 includes the following steps: S1. Based on the thickness of the formed aluminum alloy shell, control the movement of hydraulic cylinder No. 3 (210) and hydraulic cylinder No. 2 (27) to adjust the distance between the side plate (214) and the L-shaped connecting plate (28). S2. The feeding mechanism (13) injects the molten aluminum alloy liquid into the space between mold No. 1 (15) and mold No. 2 (16) through the conveying pipe (14). The cooling mechanism (19) cools mold No. 1 (15) and mold No. 2 (16). Then the driving mechanism (18) drives mold No. 2 (16) to move, so that the formed aluminum alloy shell is exposed. S3. The L-shaped connecting plate (28) is pushed up by the first hydraulic cylinder (23) so that the upper end of the L-shaped connecting plate (28) contacts the lower end of the first mold (15). The air pump is turned on so that the airflow enters through the through hole (223) and the airflow is ejected from the air outlet (218). The airflow caused by the through hole (223) cools the aluminum alloy shell. Then the demolding component pushes out the aluminum alloy shell so that when the aluminum alloy shell is fully exposed, the surface contacts the side plate (214). At this time, the aluminum alloy shell moves down by gravity and falls between the L-shaped connecting plate (28) and the side plate (214). The through hole (223) adsorbs and restricts the aluminum alloy shell. S4. The first hydraulic cylinder (23) is fully retracted, so that the upper end of the stop plate (22) is located below the first mold (15). At this time, the drive mechanism (18) drives the second mold (16) to close with the first mold (15), and then injects the aluminum alloy melt between the first mold (15) and the second mold (16) for die casting production again. S5. The second hydraulic cylinder (27) retracts, causing the stop plate (22) to rotate. Due to the adsorption of the through hole (223), the aluminum alloy shell rotates together with the stop plate (22). When the stop plate (22) is parallel to the inclined plate (216), the aluminum alloy shell moves and slides onto the surface of the inclined plate (216). The gas ejected from the air outlet (218) cools the aluminum alloy shell on the one hand and pushes the aluminum alloy shell to move on the other hand, so that the aluminum alloy shell slides into the material tray (21). S6. Pull out the material tray (21), remove the aluminum alloy shell, and then put the material tray (21) back in.
