Description

Technical Field

[0001] This invention relates to the field of precision mold technology, specifically to a precision mold with an internal circulation heat dissipation system and its method. Background Technology

[0002] Precision molds play a crucial role in molding processes such as injection molding and die casting, and the design of their cooling systems directly affects the molding quality and production efficiency of the products.

[0003] In existing technologies, after long-term operation with circulating cooling water, calcium and magnesium ions, rust, and plastic particles in the water will continuously deposit on the inner wall of the water channel, gradually forming hard scale and solid impurities. Due to the small heat dissipation space inside the mold, traditional hard cleaning brushes cannot reach in, and the pressure of the direct water flow from the high-pressure water gun decreases quickly, making it impossible to remove the scale on the mold. After long-term use, water channel partial blockage and flow reduction problems are likely to occur. Summary of the Invention

[0013] Preferably, a plurality of sliding rods are fixedly installed on the inner wall of the frame, and the inner wall of the upper mold is slidably connected to the outer surface of the sliding rods.

[0014] A method for using a precision mold with an internal circulation heat dissipation system includes the following steps: S1: The operator issues a start command through the controller, and the water pump draws low-temperature cooling water from the water storage tank and sends it into the heat dissipation cavity of the upper and lower molds through the delivery pipe. The cooling water continuously carries away the high-temperature heat generated by the molding process. The water that has absorbed heat and heated up flows back to the water storage tank along the circulation pipe. The semiconductor cooling chip continuously dissipates heat and cools the outer wall of the water storage tank, achieving uninterrupted internal circulation cooling. After the raw material inside the cavity is cooled and shaped, the electric push rod lifts the upper mold and removes the finished workpiece. The injection molding or die casting production is carried out in a cycle. After long-term water cooling operation, calcium and magnesium scale will be attached to the inner wall of the heat dissipation cavity. After the controller reaches the preset cleaning cycle, the cleaning component will be automatically started. S2: The controller cuts off the power supply to the semiconductor cooling chip, activates the heater fixed to the inner wall of the water tank, and heats the water inside the tank. The operator then removes the sealing plug, and the high-temperature hot water is pumped into the heat dissipation chamber. The hot water soaks the pre-installed shape memory alloy tube inside the chamber, causing it to expand radially when heated. Multiple sets of scrapers evenly distributed on the outer wall of the tube expand outwards, tightly adhering to the inner wall of the heat dissipation chamber to ensure sufficient contact pressure for scraping away scale. A mounting plate is welded to the outside of the upper mold. Two sets of connecting boxes are symmetrically installed on the upper surface of the mounting plate and the inner bottom wall of the frame. The rotating motor is started, and the drive is transmitted through the engagement of the conical wheel. The rotating shaft rotates at a constant speed, and the two ends of the rotating shaft are synchronously fixed to the turntable. The fixed connecting column on the surface of the turntable moves in a circle with the turntable. The outer movable frame slides horizontally back and forth along the limit block. The bottom slider of the movable frame slides into the groove inside the bottom wall of the connecting box, which constrains the sliding trajectory of the movable frame and avoids transmission deviation. The fixed connecting frame on the outside of the movable frame moves horizontally back and forth synchronously with the movable frame. When the connecting frame moves back and forth, it drives the entire shape memory alloy tube to shuttle back and forth inside the heat dissipation cavity. The scraper that expands and adheres to the tube wall continuously scrapes and peels off the scale attached to the inner wall of the heat dissipation cavity. The scraped scale debris flows back to the storage tank with the circulating hot water. S3: A third conical wheel is fixed to the end of the rotating shaft away from the fixed frame. A rotating column is rotatably mounted on the outside of the connecting frame. A connecting gear and a fourth conical wheel are fixed to the outer wall of the rotating column. The fourth conical wheel meshes with the third conical wheel. A rotating gear is also rotatably mounted on the outside of the connecting frame. The rotating gear meshes with the connecting gear and the rack plate fixed to the inner wall of the connecting box. When the connecting frame moves horizontally back and forth with the moving frame, the rotating gear rolls and rotates along the rack plate, sequentially driving the connecting gear, rotating column, fourth conical wheel, and third conical wheel to drive the rotating shaft to rotate continuously. Ultimately, this drives the shape memory alloy tube to reciprocate. The rotating shaft rotates circumferentially, and multiple sets of scrapers on the outer wall scrape away the scale on the inner wall of the heat dissipation cavity from all angles without dead angles. During the rotation of the rotating shaft, the incomplete gear fixed on the shaft rotates synchronously. The incomplete gear intermittently meshes with the fixed gear assembled inside the fixed block. After the fixed gear meshes and drives the transmission, it drives the toothed plate to move back and forth along the slide rail. The sliding plate at the bottom of the toothed plate is embedded in the slide rail for sliding guidance. The hammer fixed on the outside of the toothed plate intermittently strikes the outer wall of the upper and lower molds. The mold as a whole generates high-frequency micro-vibration, which loosens and cracks the hard scale attached to the inner wall of the heat dissipation cavity. Combined with the rotating scraper, the clump of scale is quickly peeled off.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention incorporates a cleaning component, which utilizes the thermal expansion property of shape memory alloy to introduce hot water into the heat dissipation cavity during the cleaning process. Simultaneously, by reciprocatingly pulling the two ends of the shape memory alloy tube, the tube, in conjunction with the scraper, moves back and forth within the heat dissipation cavity, thereby achieving the purpose of cleaning scale on the inner wall of the heat dissipation cavity and preventing scale from clogging the heat dissipation cavity and affecting the flow rate of the cooling water.

[0016] Secondly, by incorporating a vibration component, the present invention enables the shape memory alloy tube to rotate continuously during the pulling process, while simultaneously driving the hammer to strike and vibrate the upper and lower molds, further assisting the cleaning component in removing scale and enhancing the scale removal effect.

By setting up the cleaning component 3, the device utilizes the thermal expansion characteristic of the shape memory alloy tube 302 to input hot water into the heat dissipation cavity 210 during the cleaning process. At the same time, by reciprocatingly pulling the two ends of the shape memory alloy tube 302, the shape memory alloy tube 302, together with the scraper 303, reciprocates inside the heat dissipation cavity 210, thereby achieving the purpose of cleaning the scale on the inner wall of the heat dissipation cavity 210, avoiding scale blockage of the heat dissipation cavity 210 and affecting the flow rate of the heat dissipation water.

[0022] Each connecting box 305 has a locking block 5 and a locking frame 6 fixedly installed on its outer surface. Each locking block 5 is snapped into the inside of the locking frame 6. The installation of the locking block 5 and the locking frame 6 serves to lock the connecting box 305.

[0023] Each connecting box 305 has a limit block 7 fixedly installed on its inner wall. The inner wall of each limit block 7 is slidably connected to the outer surface of the moving frame 312. The installation of the limit block 7 serves to limit the movement trajectory of the moving frame 312.

[0024] Each connecting frame 313 has a slider 8 fixedly installed on its bottom surface, and each connecting box 305 has a groove 9 on its inner bottom wall. Each slider 8 is slidably connected inside the groove 9. The installation of the slider 8 and the groove 9 serves to limit the movement trajectory of the connecting frame 313.

[0025] Each connecting frame 313 has a connecting bearing 10 fixedly installed on its outer surface. The outer surface of the inner ring of each connecting bearing 10 is fixedly connected to the outer surface of the fixed frame 315. The installation of the connecting bearing 10 plays a role in stabilizing the fixed frame 315, thereby ensuring the stability of the rotation of the fixed frame 315.

[0026] Several slide rods 13 are fixedly installed on the inner wall of the frame 1. The inner wall of the upper mold 203 is slidably connected to the outer surface of the slide rods 13. The slide rods 13 play a role in positioning the upper mold 203, thereby preventing the upper mold 203 from shifting position.

[0027] The specific implementation method of this embodiment is as follows: The operator issues a start command through the controller 206, the water pump 205 draws low temperature cooling water from the water storage tank 204, and sends it into the heat dissipation cavity 210 of the upper mold 203 and the lower mold 201 through the delivery pipe 208. The cooling water continuously carries away the high temperature heat generated by the mold forming. The water that has absorbed heat and heated up flows back to the water storage tank 204 along the circulation pipe 209. The semiconductor cooling chip 207 continuously dissipates heat and cools the outer wall of the water storage tank 204 to achieve uninterrupted internal circulation cooling. After the raw material inside the cavity is cooled and shaped, the electric push rod 202 lifts the upper mold 203 and takes out the finished workpiece. The injection molding or die casting production is carried out in a cycle. After the mold has been water-cooled for a long time, calcium and magnesium scale will be attached to the inner wall of the heat dissipation cavity 210. After the controller 206 reaches the preset cleaning cycle, the cleaning component 3 is automatically started. The controller 206 cuts off the power supply to the semiconductor cooling chip 207, and starts the heater 301 fixed to the inner wall of the water storage tank 204 to heat the water inside the water storage tank 204. Then, the operator removes the sealing plug 316, and the high-temperature hot water is pumped into the heat dissipation cavity 210 through the water pump 205. The hot water soaks the shape memory alloy tube 302 pre-installed inside the heat dissipation cavity 210. The shape memory alloy tube 302 expands radially when heated, and multiple sets of scrapers 303 evenly distributed on the outer wall of the tube expand outward, closely adhering to the inner wall of the heat dissipation cavity 210 to ensure the contact pressure for scraping off scale. The mounting plate 304 is welded and fixed to the outside of the upper mold 203. Two sets of connecting boxes 305 are symmetrically installed on the upper surface of the mounting plate 304 and the inner bottom wall of the frame 1, respectively. The rotating motor 308 is started, and the conical wheel meshing drive drives the rotation. Shaft 306 rotates at a constant speed. Both ends of shaft 306 are synchronously fixed to turntable 310. The fixed connecting column 311 on the surface of turntable 310 moves in a circular motion with turntable 310. The outer movable frame 312 slides horizontally back and forth along the limiting block 7. The bottom slider 8 of movable frame 312 is embedded in the sliding groove 9 of the inner bottom wall of connecting box 305 and slides, constraining the sliding trajectory of movable frame 312 and avoiding transmission deviation. The outer side of movable frame 312 is fixed to connecting frame 313, which moves horizontally back and forth synchronously with movable frame 312.

The scraper 303, which expands and adheres to the tube wall, continuously scrapes and peels off the scale attached to the inner wall of heat dissipation cavity 210.

The outer surface of each connecting frame 313 is rotatably connected to a rotating column 402. The outer surface of each rotating column 402 is fixedly mounted with a connecting gear 403 and a fourth conical wheel 404. The outer surface of each fourth conical wheel 404 meshes with the outer surface of the third conical wheel 401. The outer surface of each connecting frame 313 is rotatably connected to a rotating gear 405. The inner wall of each connecting box 305 is fixedly mounted with a rack plate 406. The outer surface of each rotating gear 405 meshes with the outer surface of the connecting gear 403 and the upper surface of the rack plate 406. The upper surface of the mounting plate 304 and the inner bottom wall of the frame 1 are also connected. Each component is fixedly installed with a fixing block 407. The inner wall of each fixing block 407 is rotatably connected with a fixing gear 408. The inside of each fixing block 407 is slidably connected with a toothed plate 409.

A striking hammer 411 is fixedly installed on the outer surface of the toothed plate 409. By setting a vibration component 4, the memory alloy tube 302 is continuously rotated during the pulling process. At the same time, the striking hammer 411 drives the upper mold 203 and the lower mold 201 to strike and vibrate, further assisting the cleaning component 3 in cleaning scale and further increasing the good effect of scale cleaning.

[0030] Each toothed plate 409 has a slide plate 11 fixedly installed on its bottom surface, and each fixed block 407 has a slide rail 12 on its inner wall. Each slide plate 11 is slidably connected inside the slide rail 12. The installation of the slide plate 11 and the slide rail 12 serves to limit the movement trajectory of the toothed plate 409.

[0031] The specific implementation of this embodiment is as follows: A third conical wheel 401 is fixed to one end of the rotating shaft 314 away from the fixed frame 315. A rotating column 402 is rotatably mounted on the outer side of the connecting frame 313. A connecting gear 403 and a fourth conical wheel 404 are fixed to the outer wall of the rotating column 402 respectively. The fourth conical wheel 404 meshes with the third conical wheel 401. A rotating gear 405 is also rotatably mounted on the outer side of the connecting frame 313. The rotating gear 405 simultaneously meshes with the connecting gear 403 and the rack plate 406 fixed to the inner wall of the connecting box 305. When the connecting frame 313 moves horizontally back and forth with the moving frame 312, the rotating gear 405 rolls and rotates along the rack plate 406, sequentially driving the connecting gear 403, the rotating column 402, the fourth conical wheel 404, and the third conical wheel 401 to drive the rotating shaft 314 to rotate continuously, ultimately driving the connecting shaft 314 to rotate. While the shape memory alloy tube 302 reciprocates, it rotates circumferentially. Multiple sets of scrapers 303 on the outer wall scrape away the scale on the inner wall of the heat dissipation cavity 210 from all angles without dead angles. During the rotation of the rotating shaft 306, the incomplete gear 410 fixed on the shaft rotates synchronously. The incomplete gear 410 intermittently meshes with the fixed gear 408 mounted inside the fixed block 407. After the fixed gear 408 meshes and drives the toothed plate 409 to move back and forth along the slide rail 12, the bottom slide plate 11 of the toothed plate 409 is embedded in the slide rail 12 for sliding guidance. The outside of the toothed plate 409 is fixed with a hammer 411, which intermittently and reciprocates with the toothed plate 409 to strike the outer wall of the upper mold 203 and the lower mold 201. The mold as a whole generates high-frequency micro-vibration, which loosens and cracks the hard scale attached to the inner wall of the heat dissipation cavity 210. With the help of the rotating scraper 303, the clump of scale is quickly peeled off.

[0032] A method for using a precision mold with an internal circulation heat dissipation system includes the following steps: S1: The operator issues a start command through the controller 206. The water pump 205 draws low-temperature cooling water from the water storage tank 204 and sends it through the delivery pipe 208 into the heat dissipation cavity 210 of the upper mold 203 and the lower mold 201. The cooling water continuously carries away the high-temperature heat generated by the mold forming. The water that has absorbed heat and heated up flows back to the water storage tank 204 along the circulation pipe 209. The semiconductor cooling chip 207 continuously dissipates heat and cools the outer wall of the water storage tank 204, realizing uninterrupted internal circulation cooling. After the raw material inside the cavity is cooled and shaped, the electric push rod 202 lifts the upper mold 203 and takes out the finished workpiece. The injection molding or die casting production is carried out in a cycle. After long-term water cooling operation of the mold, calcium and magnesium scale will be attached to the inner wall of the heat dissipation cavity 210. After the controller 206 reaches the preset cleaning cycle, the cleaning component 3 is automatically started. S2: Controller 206 cuts off the power supply to the semiconductor cooling chip 207, starts the heater 301 fixed to the inner wall of the water storage tank 204, and heats the water inside the water storage tank 204. Then, the operator removes the sealing plug 316, and the high-temperature hot water is pumped into the heat dissipation cavity 210 through the water pump 205. The hot water soaks the shape memory alloy tube 302 pre-installed inside the heat dissipation cavity 210. The shape memory alloy tube 302 expands radially when heated, and multiple sets of scrapers 303 evenly distributed on the outer wall of the tube expand outward, closely adhering to the inner wall of the heat dissipation cavity 210 to ensure the contact pressure for scraping off scale. The mounting plate 304 is welded and fixed to the outside of the upper mold 203. Two sets of connecting boxes 305 are symmetrically installed on the upper surface of the mounting plate 304 and the inner bottom wall of the frame 1, respectively. The rotating motor 308 is started, and the rotating motor is driven by the meshing of the conical wheel. The rotating shaft 306 rotates at a constant speed. The two ends of the rotating shaft 306 are synchronously fixed to the turntable 310. The fixed connecting column 311 on the surface of the turntable 310 moves in a circular motion with the turntable 310. The outer movable frame 312 slides horizontally back and forth along the limiting block 7. The bottom slider 8 of the movable frame 312 is embedded in the sliding groove 9 of the inner bottom wall of the connecting box 305 and slides inside, which constrains the sliding trajectory of the movable frame 312 and avoids transmission deviation. The outer side of the movable frame 312 is fixed to the connecting frame 313, which moves horizontally back and forth synchronously with the movable frame 312. When the connecting frame 313 moves back and forth, it drives the entire shape memory alloy tube 302 to shuttle back and forth inside the heat dissipation cavity 210. The scraper 303, which expands and adheres to the tube wall, continuously scrapes and peels off the scale attached to the inner wall of the heat dissipation cavity 210. The scraped scale debris flows back to the water storage tank 204 with the circulating hot water. S3: A third conical wheel 401 is fixed to the end of the rotating shaft 314 away from the fixed frame 315. A rotating column 402 is rotatably mounted on the outer side of the connecting frame 313. A connecting gear 403 and a fourth conical wheel 404 are fixed to the outer wall of the rotating column 402 respectively. The fourth conical wheel 404 meshes with the third conical wheel 401. A rotating gear 405 is also rotatably mounted on the outer side of the connecting frame 313. The rotating gear 405 simultaneously meshes with the connecting gear 403 and the rack plate 406 fixed to the inner wall of the connecting box 305. When the connecting frame 313 moves horizontally back and forth with the moving frame 312, the rotating gear 405 rolls and rotates along the rack plate 406, sequentially driving the connecting gear 403, the rotating column 402, the fourth conical wheel 404, and the third conical wheel 401 to drive the rotating shaft 314 to rotate continuously, ultimately driving the shape memory alloy tube 3. 02 While reciprocating, the blades rotate circumferentially. Multiple sets of scrapers 303 on the outer wall scrape away the scale on the inner wall of the heat dissipation cavity 210 from all directions without dead angles. During the rotation of the rotating shaft 306, the incomplete gear 410 fixed on the shaft rotates synchronously. The incomplete gear 410 intermittently meshes with the fixed gear 408 mounted inside the fixed block 407. After the fixed gear 408 meshes and drives the toothed plate 409 to move back and forth along the slide rail 12, the bottom slide plate 11 of the toothed plate 409 is embedded in the slide rail 12 for sliding guidance, and the outside of the toothed plate 409 is fixed with a hammer 411. As the toothed plate 409 intermittently reciprocates, it strikes the outer wall of the upper mold 203 and the lower mold 201. The mold as a whole generates high-frequency micro-vibration, which loosens and cracks the hard scale attached to the inner wall of the heat dissipation cavity 210. With the help of the rotating scraper 303, the clump of scale is quickly peeled off.

[0033] The working principle of this invention is as follows: The operator issues a start command through the controller 206, the water pump 205 draws low-temperature cooling water from the water storage tank 204, and sends it into the heat dissipation cavity 210 of the upper mold 203 and the lower mold 201 through the delivery pipe 208. The cooling water continuously carries away the high-temperature heat generated by the mold forming. The water that has absorbed heat and heated up flows back to the water storage tank 204 along the circulation pipe 209. The semiconductor cooling chip 207 continuously dissipates heat and cools the outer wall of the water storage tank 204, realizing uninterrupted internal circulation cooling. After the raw material inside the cavity is cooled and shaped, the electric push rod 202 lifts the upper mold 203 and takes out the finished workpiece. The injection molding or die casting production is carried out in a cycle. After the mold has been water-cooled for a long time, calcium and magnesium scale will be attached to the inner wall of the heat dissipation cavity 210. After the controller 206 reaches the preset cleaning cycle, the cleaning component 3 is automatically started. The controller 206 cuts off the power supply to the semiconductor cooling chip 207, and starts the heater 301 fixed to the inner wall of the water storage tank 204 to heat the water inside the water storage tank 204. Then, the operator removes the sealing plug 316, and the high-temperature hot water is pumped into the heat dissipation cavity 210 through the water pump 205. The hot water soaks the shape memory alloy tube 302 pre-installed inside the heat dissipation cavity 210. The shape memory alloy tube 302 expands radially when heated, and multiple sets of scrapers 303 evenly distributed on the outer wall of the tube expand outward, closely adhering to the inner wall of the heat dissipation cavity 210 to ensure the contact pressure for scraping off scale. The mounting plate 304 is welded and fixed to the outside of the upper mold 203. Two sets of connecting boxes 305 are symmetrically installed on the upper surface of the mounting plate 304 and the inner bottom wall of the frame 1, respectively. The rotating motor 308 is started, and the conical wheel meshing drive drives the rotation. The shaft 306 rotates at a constant speed. The two ends of the rotating shaft 306 are synchronously fixed to the turntable 310. The fixed connecting column 311 on the surface of the turntable 310 moves in a circular motion with the turntable 310. The outer movable frame 312 slides horizontally back and forth along the limiting block 7. The bottom slider 8 of the movable frame 312 is embedded in the sliding groove 9 of the inner bottom wall of the connecting box 305 and slides inside, which constrains the sliding trajectory of the movable frame 312 and avoids transmission deviation. The outer side of the movable frame 312 is fixed to the connecting frame 313, which moves horizontally back and forth synchronously with the movable frame 312. When the connecting frame 313 moves back and forth, it drives the entire shape memory alloy tube 302 to shuttle back and forth inside the heat dissipation cavity 210. The scraper 303, which expands and adheres to the tube wall, continuously scrapes and peels off the scale attached to the inner wall of the heat dissipation cavity 210. The scraped scale debris flows back to the water storage tank 204 with the circulating hot water. A third conical wheel 401 is fixed to the end of the rotating shaft 314 away from the fixed frame 315. A rotating column 402 is rotatably mounted on the outer side of the connecting frame 313. A connecting gear 403 and a fourth conical wheel 404 are fixed to the outer wall of the rotating column 402. The fourth conical wheel 404 meshes with the third conical wheel 401. A rotating gear 405 is also rotatably mounted on the outer side of the connecting frame 313. The rotating gear 405 simultaneously meshes with the connecting gear 403 and a rack plate 406 fixed to the inner wall of the connecting box 305. When the connecting frame 313 moves horizontally back and forth with the moving frame 312, the rotating gear 405 rolls and rotates along the rack plate 406, sequentially driving the connecting gear 403, the rotating column 402, the fourth conical wheel 404, and the third conical wheel 401 to drive the rotating shaft 314 to rotate continuously, ultimately driving the shape memory alloy tube 30 2. While reciprocating, the blades rotate circumferentially. Multiple sets of scrapers 303 on the outer wall scrape away the scale on the inner wall of the heat dissipation cavity 210 from all directions without dead angles. During the rotation of the rotating shaft 306, the incomplete gear 410 fixed on the shaft rotates synchronously. The incomplete gear 410 intermittently meshes with the fixed gear 408 mounted inside the fixed block 407. After the fixed gear 408 meshes and drives the toothed plate 409 to move back and forth along the slide rail 12, the bottom slide plate 11 of the toothed plate 409 is embedded in the slide rail 12 for sliding guidance, and the outside of the toothed plate 409 is fixed with a hammer 411. As the toothed plate 409 intermittently reciprocates, it strikes the outer wall of the upper mold 203 and the lower mold 201. The mold as a whole generates high-frequency micro-vibration, which loosens and cracks the hard scale attached to the inner wall of the heat dissipation cavity 210. With the help of the rotating scraper 303, the clump of scale is quickly peeled off.
