Aluminum alloy die-casting molds can manufacture complex and precise aerospace components, meeting the dual demands of lightweighting and high performance in this field, providing strong support for the development of the aerospace industry. Besides the automotive and aerospace sectors, the electronics industry also has a wide demand for aluminum alloy die-casting molds. As electronic products become thinner and smaller, higher requirements are placed on the manufacturing precision and heat dissipation performance of components. Products produced by aluminum alloy die-casting molds have excellent thermal conductivity and exquisite appearance, effectively meeting these needs of the electronics industry.

The first annular fixing block is sleeved on the extrusion mold and fixedly connected to the extrusion mold. When the first pneumatic piston rod is activated, its movable end drives the extrusion mold, the first annular fixing block and the annular trimming blade to move down synchronously. The sliding limiting rod slides along the first extrusion groove to vertically limit the annular trimming blade and ensure its stable downward movement. When the annular trimming blade contacts the contact sliding block, it compresses the contact sliding block to slide along the second extrusion groove and compresses the second extrusion spring. The trimming blade slides along the outer wall of the contact sliding block with a suitable shape to accurately remove the flash of the aluminum alloy after die casting.

[0010] This invention provides a lightweight aluminum alloy die-casting mold. It has the following beneficial effects: 1. This lightweight aluminum alloy die-casting mold is equipped with a trimming device. After the first pneumatic piston rod is activated, the extrusion mold drives the annular trimming blade downward. The sliding limit rod is precisely limited in the first extrusion groove to ensure stable movement of the trimming blade. When the trimming blade contacts the matching sliding block, it compresses the second extrusion spring and slides along the outer wall of the slider. This can efficiently remove the flash generated by the molten aluminum alloy after die casting, avoiding the safety hazards of manual operation. It can also realize the continuous operation of die casting and flash removal, ensuring the uniformity of flash removal, improving the appearance quality of the die-cast parts, and increasing work efficiency.
[0011] 2. This lightweight aluminum alloy die-casting mold is equipped with a lifting device. When the second pneumatic piston rod is activated, the inclined slide moves towards the center of the forming cavity under the limit of the first slide rail. The extrusion roller moves upward along the outer wall of the inclined slide, driving the connecting seat, sliding rod and lifting block to rise synchronously, ejecting the die-casting part from the forming cavity. The third extrusion spring can buffer the impact force during the ejection process to ensure stable operation. When manually removing the part, the hand needs to reach into the vicinity of the mold cavity, which is easy to touch the high temperature mold or cause operational errors due to the casting sticking, posing safety risks and taking time. This ejection mechanism does not require manual intervention and can quickly lift the casting to a position that is easy to grasp, which not only ensures the safety of the operator, but also reduces the downtime of the part removal process, speeds up the die-casting production rhythm and improves work efficiency.
[0012] 3. This lightweight aluminum alloy die-casting mold is equipped with a spraying and cooling device. A single motor drives the device to switch between cooling and spraying functions, eliminating the need for additional specialized equipment. During cooling, the first and second electric sliders adjust the position of the first L-shaped bracket. Cold air generated by the blower is sprayed out through the rotating air pipe and cooling jet pipe. The first motor drives the component to rotate, aligning the jet pipe with the forming cavity for rapid cooling of the die-casting. During mold release agent spraying, a high-pressure water pump extracts the release agent, which is then delivered through the rotating air pipe and inclined water spray pipe. The same motor drives the component to rotate, directing the water spray pipe towards the inner wall of the cavity for uniform spraying of the release agent. Traditional molds require separate cooling and spraying devices, increasing equipment investment costs and requiring manual adjustment of equipment positions. This device achieves continuous cooling and spraying operations through function switching, shortening process changeover time, improving overall production efficiency, and ensuring the quality of the die-casting by providing uniform cooling and spraying.
[0013] 4. This lightweight aluminum alloy die-casting mold is equipped with a cleaning device. When the second motor is started, the lead screw drives the third support to move towards the cavity. The third electric slider adjusts the height of the cleaning mechanism. The third motor drives the rotating shaft to rotate the cleaning brush and cleaning scraper. The brush can sweep the dust at the bottom of the cavity, and the scraper can scrape off the die-casting residue on the inner wall. At the same time, the suction pipe sucks the dust and waste into the dust collection box. When cleaning the cavity manually, it is necessary to operate in a narrow space, which is not only labor-intensive and inefficient, but also easy to scratch the inner wall of the cavity due to improper operation, affecting the accuracy of subsequent die-cast parts. This device does not require manual intervention and can cover the inner wall and bottom of the cavity in all directions, making the cleaning more thorough and efficient. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] For the first embodiment, please refer to... Figures 1-5This invention provides a technical solution: a lightweight aluminum alloy die-casting mold, including a workbench 1, a support base 2 fixedly connected to the workbench 1, a forming cavity 3 fixedly connected to the top of the support base 2, lifting openings 4 evenly distributed on the bottom of the inner wall of the forming cavity 3, a lifting device 5 fixedly connected to the inner wall of the lifting openings 4, an adapter component 6 fixedly connected to the top of the forming cavity 3, a first bracket 7 fixedly connected to the top of the workbench 1 on both sides of the support base 2, a fixed crossbeam 8 fixedly connected to the top of the first bracket 7, a fixed end of a first pneumatic piston rod 9 fixedly connected to the top of the fixed crossbeam 8, the movable end of the first pneumatic piston rod 9 passing through the fixed crossbeam 8 and fixedly connected to an extrusion mold 10, a trimming device 11 sleeved and fixedly connected to the extrusion mold 10, a spray cooling device 12 fixedly connected to one side of the first bracket 7, a cleaning device 13 fixedly connected to the top of the workbench 1 on both sides of the support base 2, the trimming device 11 including a first annular fixing block 111, a first extrusion groove 112 opened at the bottom of the first annular fixing block 111, the first extrusion groove 11... A first compression spring 113 is fixedly connected to the top of the inner wall of the first extrusion groove 112. An annular cutting blade 114 is fixedly connected to the end of the first compression spring 113 away from the top of the inner wall of the first extrusion groove 112. A sliding limiting port 115 is opened on the side of the first annular fixing block 111. A sliding limiting rod 116 is slidably connected to the inner wall of the sliding limiting port 115. One end of the sliding limiting rod 116 located inside the first extrusion groove 112 is fixedly connected to the annular cutting blade 114. The first annular fixing block 111 is sleeved on the extrusion mold 10 and fixed to the extrusion mold 10. The fixed connection and adapter component 6 includes a second annular fixing block 61. The top of the second annular fixing block 61 is provided with a second extrusion groove 62. A second extrusion spring 63 is fixedly connected to the bottom of the inner wall of the second extrusion groove 62. A contact sliding block 64 is fixedly connected to one end of the second extrusion spring 63 away from the bottom of the inner wall of the second extrusion groove 62. The second annular fixing block 61 is fixedly connected to the top of the molding cavity 3. The contact sliding block 64 is slidably connected to the inner wall of the second extrusion groove 62. The shape of the contact sliding block 64 is adapted to the annular cutting blade 114.
[0018] In use, the first pneumatic piston rod 9 is activated. The movable end of the first pneumatic piston rod 9 moves downward, causing the extrusion die 10 to move downward. The downward movement of the extrusion die 10 causes the first annular fixing block 111 to move downward. The downward movement of the first annular fixing block 111 causes the annular trimming blade 114 to move downward. Since the annular trimming blade 114 is fixedly connected to the sliding limit rod 116, the sliding limit rod 116 slides within the first extrusion groove 112, limiting the annular trimming blade 114 and ensuring its stable downward movement. When the annular trimming blade 114 contacts... When the sliding block 64 contacts, the annular cutting blade 114 presses against the sliding block 64, and the sliding block 64 presses against the second compression spring 63. The second compression spring 63 contracts under force, and at the same time, the sliding block 64 slides in the second compression groove 62. Since the shape of the sliding block 64 is adapted to the annular cutting blade 114, the annular cutting blade 114 can slide along the outer wall of the sliding block 64, thereby cleaning the flash generated after the molten aluminum alloy is die-cast, reducing the safety hazards caused by manual cleaning and improving work efficiency.
[0019] For the second embodiment, please refer to... Figures 1-7 Based on the first embodiment, the present invention provides a technical solution: the lifting device 5 includes an annular bracket 51, a connecting block 52 is fixedly connected to the top of the annular bracket 51, a sliding rod 53 is slidably connected through the top of the connecting block 52, a lifting block 512 is fixedly connected to the top of the sliding rod 53, the sliding rod 53 passes through the annular bracket 51 and is fixedly connected to a connecting seat 54, a third compression spring 55 is fixedly connected to the top of the connecting seat 54, the third compression spring 55 is sleeved on the sliding rod 53, a second bracket 56 is fixedly fixed to the top of the connecting seat 54, and a roller 57 is rotatably connected to the inner wall of the second bracket 56. The fixed end of the second pneumatic piston rod 58 is fixedly connected to the side of the bracket 51. The movable end of the second pneumatic piston rod 58 passes through the annular bracket 51 and is fixedly connected to the inclined slide table 59. The bottom of the roller 57 is slidably connected to the inclined slide table 59. The bottom of the inner wall of the annular bracket 51 is fixedly connected to the first slide rail 510.

The connecting block 52 is fixedly connected to the inner wall of the ejector opening 4. The ejector block 512 is slidably connected to the inner wall of the ejector opening 4.
[0020] In use, when the die-cast part needs to be removed after cooling and forming, the second pneumatic piston rod 58 is activated. The movable end of the second pneumatic piston rod 58 extends, causing the inclined slide table 59 to move towards the center of the forming mold cavity 3. The movement of the inclined slide table 59 causes the first sliding block 511 to slide within the first slide rail 510. The movement of the first sliding block 511 causes the inclined slide table 59 to move stably. The movement of the inclined slide table 59 compresses the roller 57. The roller 57 rotates on the inner wall of the second bracket 56 and slides upward along the outer wall of the inclined slide table 59. The movement of the roller 57 causes the connecting seat 54 to move upward. The movement of the connecting seat 54 causes the sliding rod 53 to slide within the connecting block 52. At the same time, the connecting seat 54 compresses the third compression spring 55. The third compression spring 55 contracts under force, making the operation more stable. The upward movement of the sliding rod 53 causes the lifting block 512 to move upward. The movement of the lifting block 512 lifts the die-cast part in the forming mold cavity 3, making it easier for workers to remove the die-cast part, reducing the safety hazards caused by manual removal of the die-cast part, and improving work efficiency.

One end of an L-shaped bracket 123 is connected to a partition box 1222. A partition plate 126 is fixedly connected to the inner wall of the partition box 1222. A rotating air pipe 125 is located above the partition plate 126. A rotating water pipe 127 is connected to the side of the partition box 1222 away from the rotating air pipe 125. A connecting air pipe 128 is connected to the top of the partition box 1222. A first connecting box 129 is connected to the top of the connecting air pipe 128. Cooling jet pipes 1210 are evenly connected to the top of the first connecting box 129. A connecting water pipe 1211 is connected to the bottom of the partition box 1222. A second connecting box 1212 is connected to the bottom of the connecting water pipe 1211. An inclined water spray pipe 1213 is evenly connected to the bottom of the connecting box 1212. A second L-shaped bracket 1214 is rotatably connected to the end of a rotating water pipe 127 away from the separating box 1222. The output end of a belt drive mechanism 1215 is sleeved and fixedly connected to the rotating water pipe 127.

A transport water pipe 1217 is connected to the end of the rotating water pipe 127 away from the separating box 1222. The transport water pipe 1217 is rotatably connected to the rotating water pipe 1214. The end of the 17 away from the rotating water pipe 127 is connected to the outlet of the high-pressure water pump 1218, and the inlet of the high-pressure water pump 1218 is connected to the mold release agent storage tank 1219. The second L-shaped bracket 1214 is fixedly connected to the side away from the rotating water pipe 127 with a second electric slider 1220. The second electric slider 1220 is slidably connected to a third slide rail 1221. The second slide rail 121 is fixedly connected to one side of the first bracket 7, and the third slide rail 1221 is fixedly connected to one side of the first bracket 7. The second slide rail 121 and the third slide rail 1221 are symmetrically arranged on both sides of the partition box 1222. The mold release agent storage tank 1219 is fixedly connected to the top of the workbench 1.
[0022] In use, when cooling is required after die casting, the first electric slider 122 and the second electric slider 1220 are activated. The first electric slider 122 moves towards the molding cavity 3 within the second slide rail 121, while the second electric slider 1220 moves towards the molding cavity 3 within the third slide rail 1221. The movement of the first electric slider 122 drives the first L-shaped bracket 123 to move, activating the induced draft fan 124. The air generated by the induced draft fan 124 is transported through the air outlet to the interior of the rotating air pipe 125, and then transported by the rotating air pipe 125 to the partition plate 126 inside the partition box 1222, and then transported by the connecting air pipe 128 to the first connecting... The cooling spray is ultimately ejected from the cooling jet pipe 1210 within the receiving chamber 129. Simultaneously, the first motor 1216 is activated. The drive shaft of the first motor 1216 rotates, causing the input end of the belt drive mechanism 1215 to rotate. The rotation of the input end of the belt drive mechanism 1215 causes the output end to rotate, which in turn causes the rotating water pipe 127 to rotate. The rotation of the rotating water pipe 127 causes the partition chamber 1222 to rotate, which in turn causes the connecting air pipe 128 to rotate. The rotation of the connecting air pipe 128 causes the first connecting chamber 129 to rotate, which in turn causes the cooling jet pipe 1210 to rotate, thereby distributing the cooling spray... The air pipe 1210 rotates downwards to provide air cooling for the die-casting part in the molding cavity 3. When the die-casting part needs to be removed and a release agent needs to be sprayed, the high-pressure water pump 1218 is started. The high-pressure water pump 1218 extracts the release agent from the release agent storage tank 1219 through the outlet, and then transports it through the transport water pipe 1217 to the rotating water pipe 127. The release agent is transported by the rotating water pipe 127 to the interior of the partition box 1222, and then enters the connecting water pipe 1211. It is then transported by the connecting water pipe 1211 to the interior of the second connecting box 1212, and finally sprayed out by the inclined spray pipe 1213. The rotating water pipe 127 rotates, driving the partition box 122. 2. The rotation of the partition box 1222 simultaneously drives the rotation of the connecting water pipe 1211, which in turn drives the rotation of the second connecting box 1212. The rotation of the second connecting box 1212 then drives the rotation of the inclined water spray pipe 1213, which rotates the inclined water spray pipe 1213 to the top of the molding cavity 3. The release agent is then evenly sprayed onto the inner wall of the molding cavity 3 through the inclined water spray pipe 1213. Thus, the rotation of the drive shaft of the first motor 1216 can switch between the operation of the inclined water spray pipe 1213 spraying the release agent onto the molding cavity 3 and the operation of the cooling air pipe 1210 spraying air to cool the die casting, thereby improving work efficiency and reducing costs.

[0024] In use, when the inside of the molding cavity 3 needs cleaning, the second motor 132 is started. The drive shaft of the second motor 132 rotates, causing the lead screw 134 to rotate. The rotation of the lead screw 134 causes the second sliding block 135 to move closer to the molding cavity 3 within the slide groove 133. The movement of the second sliding block 135 causes the third support 136 to move. Then, the third electric slider 138 is started. The third electric slider 138 slides upward within the fourth slide rail 137. The sliding of the third electric slider 138 causes the first connecting plate 139 to move. The movement of the first connecting plate 139 causes the third motor 1310 to move. Then, the third motor 1310 is started. The drive shaft of the third motor 1310 rotates, causing the lead screw 134 to rotate. The rotating shaft 1311 rotates, which drives the second connecting plate 1312 to rotate. The rotation of the second connecting plate 1312 drives the cleaning brush 1313 to rotate. The cleaning brush 1313 cleans the bottom of the inner wall of the molding cavity 3. At the same time, the rotation of the second connecting plate 1312 drives the cleaning scraper 1316 to rotate. The cleaning scraper 1316 scrapes off the die-casting residue on the inner wall of the molding cavity 3. Then, the dust and waste inside the molding cavity 3 are sucked into the dust collection box 1314 through the dust suction pipe 1315. This makes it easier to clean the inner wall and bottom of the molding cavity 3, avoids manual cleaning, reduces labor costs, and improves cleaning efficiency.
