Description

Technical Field

[0001] The invention relates to the technical field of injection molding cooling, and in particular to a rapid cooling device for a medical device injection mold. Background Art

[0002] Injection molding is a common and efficient manufacturing method in the production process of medical devices. Injection molding technology can process plastic products with complex shapes, precise dimensions or inserts, with high production efficiency and easy to realize automated production. During the injection molding process, the cooling speed of the mold has a crucial impact on the quality and production efficiency of the product. The existing device has a poor cooling effect on the mold during the production process.

[0003] For example, a high-efficiency cooling device for plastic molds provided by authorization announcement No. CN115635660B can push the balls in the water channel to move along the trend when the cooling water flows in the water channel. After the balls enter the heat-resistant rubber tube, they will squeeze the capsule outward when passing through the heat-resistant rubber tube, and compress the gas in the through groove along the air hole. At this time, the steel ball in the lower inner hole is embedded in the cone mouth for sealing, and the steel ball in the upper cone mouth is lifted up, so that the air is discharged from the upper end of the through groove. After the balls move, the airbag returns to its position and exhausts air in the through groove along the air hole. At this time, the steel ball in the upper inner hole is embedded in the cone mouth for sealing, and the steel ball in the lower cone mouth is lifted up, so that the outside air enters the through groove, thereby assisting the heat dissipation in the die seat by reciprocatingly exchanging the air in the through groove; the reciprocating expansion and contraction of the capsule causes cavitation of the fluid under high-speed flow and pressure change conditions, that is, when the pressure of the liquid at the contact point with the solid surface is lower than its vapor pressure, bubbles will form near the solid surface. In addition, the gas dissolved in the liquid may also precipitate to form bubbles. Subsequently, when the bubbles flow to a place where the liquid pressure exceeds the bubble pressure, the bubbles will collapse, generating a huge impact force and high temperature at the moment of collapse, so that the surface of the ball and the inner wall of the water channel are subjected to repeated effects of this impact force, which can effectively remove the scale on both, realizing the self-cleaning function of the cooling system.

[0004] It has major drawbacks: when the capsule is squeezed by the balls alone, the cavitation effect obtained has a poor impact effect on the internal scale and a poor gas flow cooling effect; and in the process of the balls being driven by the water flow, since the water channel is bent at the side wall, during the transportation process, due to the effects of the gravity and buoyancy of the balls, the transportation efficiency is poor, resulting in a poor cleaning effect on the internal scale and a poor gas flow effect; and the balls are continuously transported in the water channel, and the balls are recycled, and the scale attached to the surface of the balls will remain inside again, resulting in a poor cleaning effect. Summary of the invention

[0005] In an embodiment of the present application, by providing a rapid cooling device for a medical device injection mold, the problems in the prior art are solved. When a round bead is used to extrude a capsule alone, the cavitation effect obtained has a poor impact effect on internal water scale and a poor gas flow cooling effect. And during the process of driving the round bead to move by water flow, since the water path is bent on the side wall, during the transportation process, due to the action of the gravity and buoyancy of the round bead, the transportation efficiency is poor, resulting in a poor cleaning effect on internal water scale and a poor gas flow effect. And the round bead is continuously transported in the water path, and the round bead is recycled, and the water scale attached to the surface of the round bead will remain inside again, and the cleaning effect is poor. It is realized that the axes of the first cooling tank, the second cooling tank and the third cooling tank are on the same horizontal plane, and the axes of the fourth cooling tank and the fifth cooling tank and the bent axis of the sixth cooling tank are on the same horizontal plane, which can effectively avoid the problem that the transportation ball has a poor transportation effect due to a large gravity or a large buoyancy, resulting in a poor cleaning effect on internal water scale and a poor gas flow effect. And the transportation ball can be discharged for cleaning to avoid the accumulation of water scale on the surface after long-term use. And the inner walls of the first cooling tank, the second cooling tank, the third cooling tank, the fourth cooling tank, the fifth cooling tank, the sixth cooling tank and the connecting pipe can be completely attached by the transportation ball to scrape and clean the attached water scale.

Third, by changing the extrusion film into an inflatable structure, the conveying balls can be intercepted. When the intercepted conveying balls pass through the extrusion film, the impact force of the water flow will be increased, improving the cleaning effect on the water scale inside the connecting pipes and the extrusion film; when the conveying balls press the extrusion film, the connecting pipes will be driven to move and stretch to a farther distance, and when reset, a greater vibration effect and gas flow effect will be provided, improving the vibration cleaning effect; through the retraction of the extrusion film, the inner diameter becomes the same as the diameter of the connecting pipes. When the conveying balls are conveyed, they can be completely cleaned, avoiding that when cleaning the extrusion film, the conveying balls drive the whole extrusion film to move forward, resulting in incomplete cleaning of the extrusion film; and during the expansion and retraction process of the extrusion film, the surrounding air can also be driven to flow; when the gas is conveyed in the second passage, the third connecting passage, and the air supply passage, the lower mold is also cooled. Fourth, by leaving a gap between the extrusion film and the conveying balls, when the water flow is continuously conveyed, the water flow can impact a single side, thereby cleaning the water scale in front and improving the cleaning effect. And there are multiple cavities, and any single-side cavity can be arbitrarily controlled to expand, so as to completely clean the inside of the connecting pipes; and when a gap is generated between the conveying balls and the extrusion film, when the water flow passes through the gap, the internal water pressure will change, causing the connecting pipes to vibrate, further improving the cleaning and gas flow effects.

There are multiple impact ports 413, and they are evenly arranged in a ring. The impact ports 413 are inclined. One end of the impact port 413 away from the water delivery channel 411 is provided with a water inlet ring 414, and the water inlet ring 414 is in a ring shape; One end of the water inlet channel 415 communicates with the water inlet ring 414.

[0023] During the use process, the injection molding material is poured through the injection port on the upper mold 120. The injection molding material enters the molding groove 112 and is cooled and molded. During the cooling and molding process, water is supplied by the water pump 150. The water flow enters the water inlet channel 415, the water inlet ring 414, the impact port 413, and the water delivery channel 411 in sequence through the water inlet pipe 430. The incoming water enters the first cooling tank 210, the second cooling tank 220, and the third cooling tank 230 in sequence, or the fourth cooling tank 240, the fifth cooling tank 250, and the sixth cooling tank 260. And when the water flow enters the first cooling tank 210, the second cooling tank 220, the third cooling tank 230, the fourth cooling tank 240, and the fifth cooling tank 250, it will enter the connecting pipe 310. When the water flow is discharged through the second cooling tank 220 and the fifth cooling tank 250, it is discharged into the protective cover 160 and discharged through the drain pipe 170; during the water flow transportation process, when the internal water scale needs to be cleaned and when the device needs to be cooled down, the telescopic rod 420 extends and retracts intermittently, transporting the conveying ball 440 into the first cooling tank 210 and the fourth cooling tank 240, making the water flow contact the conveying ball 440 and be transported together. During the retraction process of the telescopic rod 420, the conveying ball 440 drops into the water delivery channel 411 by gravity and is located at the front end of the output end of the telescopic rod 420. When the length of the output end of the telescopic rod 420 becomes longer, the conveying ball 440 is moved to the front end of the impact port 413. Through the impact force of the water flow in the impact port 413, it is impacted forward and enters the first cooling tank 210, the second cooling tank 220, and the third cooling tank 230 in sequence, or the fourth cooling tank 240, the fifth cooling tank 250, and the sixth cooling tank 260. And during the internal movement of the conveying ball 440, the attached water scale inside is cleaned and pushed forward. When the conveying ball 440 enters the connecting pipe 310 and moves to the extrusion film 320, it extrudes the extrusion film 320 outward, causing the extrusion film 320 to expand outward, making the air flow in the cooling pipe 610 and the first connecting channel 630, and generating a cavitation cleaning effect; after the conveying ball 440 is discharged through the drain pipe 170 into the protective cover 160, it is cleaned and then put back into the storage pipe 412 again.

[0024] Compared with the prior art, making the axes of the first cooling tank 210, the second cooling tank 220, and the third cooling tank 230 be on the same horizontal plane, and making the axes of the fourth cooling tank 240 and the fifth cooling tank 250 and the bent axis of the sixth cooling tank 260 be on the same horizontal plane can effectively avoid the problem that the conveying effect of the conveying ball 440 becomes poor due to its large gravity or large buoyancy, resulting in a poor cleaning effect on the internal scale and a poor gas flow effect; and it can make the conveying ball 440 be discharged clean, avoiding the accumulation of scale on the surface after long-term use; and the inner walls of the first cooling tank 210, the second cooling tank 220, the third cooling tank 230, the fourth cooling tank 240, the fifth cooling tank 250, the sixth cooling tank 260, and the connecting pipe 310 can be completely attached by the conveying ball 440 to scrape and clean the scale attached to the inner walls.

[0025] Embodiment 2: When Embodiment 1 is in use, through the conveying of the conveying ball 440 in the connecting pipe 310, the scale attached to the inner wall of the connecting pipe 310 is cleaned, and the device is cooled down. However, during use, the cleaning effect and the cooling effect are poor. Based on this, the solution of Embodiment 1 is improved as Figures 16 - 17 shown: Both ends in the length direction of the connecting pipe 310 are fixed at both ends in the length direction of the installation groove 270; The cleaning assembly 300 further includes a connecting ring 330 and a fixing groove 340; The number of the connecting rings 330 is the same as the number of intervals between the multiple installation ports 311 and they correspond one by one; The number of the fixing grooves 340 is the same as the number of the connecting rings 330 and they correspond one by one; Both the connecting ring 330 and the fixing groove 340 are cylindrical bodies that penetrate along their axes. The axes of the connecting ring 330 and the fixing groove 340 are on the same straight line, and the axis of the connecting ring 330 is on the same straight line as the axis of the connecting pipe 310; The inner ring of the connecting ring 330 is fixed on the outer ring of the connecting pipe 310. The fixing groove 340 is opened on the inner wall of the installation groove 270, and the connecting ring 330 is fixed in the fixing groove 340; The positions of the multiple connecting rings 330 are fixed at intervals on the connecting pipe 310.

[0026] During use, when the conveying ball 440 conveys forward and presses the extrusion film 320, it will pull the connecting pipe 310 to move in the conveying direction. And after the conveying ball 440 passes through the extrusion film 320, due to the elastic force, the connecting pipe 310 will reset by its own elastic force. During this process, vibrations are generated to vibrate the scale adhering to the inner walls of the connecting pipe 310 and the extrusion film 320. And during the process of the overall movement and reset of the connecting pipe 310, it will drive the air inside the cooling pipe 610 and the first connecting channel 630 to flow.

[0027] By fixing the connecting pipe 310 at intervals in the fixed groove 271, after the conveying ball 440 passes through the extrusion film 320, the connecting pipe 310 can reset by elastic force, which can bring a vibration effect. Through the vibration effect, the cleaning effect of the scale adhering to the inner walls of the connecting pipe 310 and the extrusion film 320 can be improved. And during the process of the conveying ball 440 driving the overall movement and reset of the connecting pipe 310, it drives the air inside the cooling pipe 610 and the first connecting channel 630 to flow, thereby improving the cooling effect of the overall mold.

[0028] Embodiment 3: When Embodiment 2 is in use, through the conveyance of the conveying ball 440, the scale on the inner walls of the connecting pipe 310 and the extrusion film 320 is cleaned, and the device is cooled. However, during the use process, the cleaning effect and the cooling effect of the scale inside the connecting pipe 310 by the conveying ball 440 alone are relatively poor. Based on this, the solution of Embodiment 2 is improved as follows Figures 18 - 22 shown: The inside of the extrusion film 320 is hollow and is an airbag structure; It further includes an expansion assembly 500. The number of the expansion assemblies 500 is the same as the number of the cleaning assemblies 300 and they correspond one by one. The expansion assembly 500 includes a connecting member and an air pump member 540; The connecting member includes a second connecting channel 510, a third connecting channel 520, an air delivery pipe 530 and an air supply channel 550; The lower mold 110 is provided with a second connecting channel 510, a third connecting channel 520 and an air supply channel 550 inside. The length direction of the second connecting channel 510 is parallel to the length direction of the connecting pipe 310; The number of the third connecting channel 520 and the air delivery pipe 530 is the same as the number of the extrusion films 320 in a single cleaning assembly 300 respectively and they correspond one by one; One side of the second connecting channel 510 is provided with a third connecting channel 520. One end of the air delivery pipe 530 is communicated with the end of the third connecting channel 520 far from the second connecting channel 510. The end of the air delivery pipe 530 far from the third connecting channel 520 is communicated with the internal cavity of the extrusion film 320; The air pump member 540 is fixed to one side of the lower mold 110. The air pump member 540 is equipped with an air pump inside, and both ends of the air supply channel 550 are respectively communicated with the air pump output end inside the air pump member 540 and the second connecting channel 510; When the air pump inside the air pump member 540 works, it causes the cavity of the extrusion film 320 to expand or contract; An insulating layer is installed between the air pump member 540 and the lower mold 110, and the air delivery pipe 530 is a telescopic pipe; The insulating layer installed between the air pump member 540 and the lower mold 110 can prevent the lower mold 110 from being affected when the air pump inside the air pump member 540 works. The air delivery pipe 530 being a telescopic pipe can prevent the deformation of the connecting pipe 310 from affecting the gas delivery.

[0029] When the conveying ball 440 enters the inside of the connecting pipe 310, the air pump inside the air pump member 540 inflates the extrusion film 320 to reduce the diameter of the extrusion film 320. When the conveying ball 440 is conveyed to the extrusion film 320, it will be intercepted by the extrusion film 320. When the conveying ball 440 is extruded out of the extrusion film 320 by the water pressure, the water pressure instantaneously increases, impacting the water scale in the connecting pipe 310 and the extrusion film 320; and after the diameter of the extrusion film 320 is reduced, when the conveying ball 440 squeezes the extrusion film 320, it will drive the connecting pipe 310 to move and stretch to a farther distance. When resetting, it provides a greater vibration effect and gas flow effect; and when the extrusion film 320 needs to be completely cleaned, the extrusion film 320 is evacuated by the air pump inside the air pump member 540, causing the extrusion film 320 to retract, and the inner diameter becomes the same as the diameter of the connecting pipe 310. When the conveying ball 440 is conveyed, it can be completely cleaned.

[0030] By making the extrusion film 320 into an inflatable structure, the conveying ball 440 can be intercepted. When the intercepted conveying ball 440 passes through the extrusion film 320, it will increase the impact force of the water flow, improving the cleaning effect of the water scale inside the connecting pipe 310 and the extrusion film 320; when the conveying ball 440 squeezes the extrusion film 320, it will drive the connecting pipe 310 to move and stretch to a farther distance. When resetting, it provides a greater vibration effect and gas flow effect, improving the vibration cleaning effect; through the retraction of the extrusion film 320, the inner diameter becomes the same as the diameter of the connecting pipe 310. When the conveying ball 440 is conveyed, it can be completely cleaned, avoiding that when cleaning the extrusion film 320, the conveying ball 440 drives the whole extrusion film 320 to move forward, resulting in incomplete cleaning of the extrusion film 320; and during the expansion and retraction process of the extrusion film 320, it can also drive the surrounding air to flow; when the gas is conveyed in the second connecting channel 510, the third connecting channel 520 and the air supply channel 550, it also cools the lower mold 110.

[0031] Example 4: When Example 3 is in use, the conveying ball 440 presses the extrusion film 320, thereby improving the cleaning effect on the inner wall of the connecting pipe 310 and the cooling effect of the device. However, when in use, the device can also be improved to further enhance the cleaning of the inner circle of the connecting pipe 310 and the extrusion film 320 and the cooling effect of the device. Based on this, the solution of Example 3 is improved as follows Figures 23 - 25 as shown: The cleaning component 300 further includes a partition film 321; The partition film 321 is fixed inside the cavity of the extrusion film 320. There are multiple partition films 321, and they are distributed in a ring shape. The multiple partition films 321 divide the cavity of the extrusion film 320 into multiple non-communicating cavities; The number of the connecting members is the same as the number of the cavities of the extrusion film 320 separated by the partition film 321, and they correspond one by one; The number of air pumps in the air pump component 540 is the same as the number of the connecting members, and they correspond one by one; When the air pumps in the air pump component 540 work, the cavities at different positions inside the extrusion film 320 expand or contract.

[0032] During the use process, when the conveying ball 440 touches the extrusion film 320, a cavity inside the extrusion film 320 can be controlled to retract alone, creating a gap between the conveying ball 440 and one side of the extrusion film 320. When the conveying ball 440 touches the extrusion film 320 and wants to squeeze open the extrusion film 320 through the water pressure, the water will flow out from the gap and impact the scale in front.

[0033] By leaving a gap between the extrusion film 320 and the conveying ball 440, when the water is continuously conveyed, it can impact a single side, thereby cleaning the scale in front and improving the cleaning effect. And there are multiple cavities, and any single side cavity can be controlled to expand arbitrarily, so as to completely clean the inside of the connecting pipe 310; and when a gap is generated between the conveying ball 440 and the extrusion film 320, when the water flows through the gap, the internal water pressure will change, causing the connecting pipe 310 to vibrate, further improving the cleaning and gas flow effects.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
