Description
Technical Field
[0001] The invention relates to the technical field of injection molds, in particular to an injection mold for a carbon fiber composite material impeller. Background Art
[0002] Carbon fiber composites are inorganic high-performance fibers that are converted from organic fibers through a series of heat treatments and have a carbon content of more than 90%. They are a new material with excellent mechanical properties. They have the inherent characteristics of carbon materials and the softness and processability of textile fibers. They are a new generation of reinforcing fibers. Carbon fiber composites are often used as structural parts in various industries, such as in the interior of automobiles and electrical products.
[0003] At present, when carbon fiber composite materials are injection molded, they need to be heated to ensure that the carbon fiber composite materials can fill the injection mold. However, after heating, the required cooling time is also correspondingly long. The existing injection mold has a poor cooling effect. Not only is it easy to cause deformation of the carbon fiber composite material impeller after demoulding, it also slows down the injection molding time of each impeller and reduces the efficiency of injection molding. Summary of the invention
[0004] In view of the above situation, in order to remedy the above existing defects, the present invention provides an injection mold for a carbon fiber composite material impeller.
[0005] The present invention provides the following technical solution: An injection mold of a carbon fiber composite material impeller proposed in the present invention comprises: a mold body, an injection cooling mechanism and an airflow heat dissipation mechanism;
[0006] An injection molding cooling mechanism is fixedly installed on one side of the mold body, and the injection molding cooling mechanism includes a cooling accommodating bin, a cooling water separation membrane is fixedly installed in the cooling accommodating bin, and a plurality of uniformly distributed gasification accommodating bins are fixedly installed in the cooling accommodating bin, and alcohol is arranged in the gasification accommodating bin;
[0007] An airflow heat dissipation mechanism is installed on one side of the cooling storage bin.
[0008] Furthermore, a supporting filter is provided on the lower side of the cooling water-dividing membrane, which can support the cooling water-dividing membrane without hindering the circulation of air, and the supporting filter is fixedly connected to the cooling containing bin.
[0009] Furthermore, the cooling storage bin is provided with a number of evenly distributed heat dissipation fins, which can absorb the heat on the surface of the mold body and transfer the heat to the coolant contained in the cooling storage bin, so that the heat in the mold body can be quickly absorbed;
[0010] The heat dissipation fins are fixedly connected to the mold body, which improves the stability of the heat dissipation fins, reduces the probability of the heat dissipation fins being detached, and improves the heat dissipation effect of the heat dissipation fins.
[0011] Furthermore, a pressure relief pipe is provided in the cooling storage chamber. When the airflow transmission shaft rotates too fast, that is, the air pressure above the coolant is too low, the pressure relief membrane will open, so that the pressure relief pipe connects the upper and lower sides of the coolant, reducing the possibility of overload and damage to the airflow motor.
[0012] The pressure relief pipe runs through the cooling water separation membrane, the supporting filter and the heat dissipation fins, so that air can pass through the cooling water separation membrane and the supporting filter. At the same time, the heat dissipation fins can improve the balance of the pressure relief pipe and reduce the probability of the pressure relief pipe tilting.
[0013] Furthermore, a pressure relief membrane is fixedly installed in the pressure relief pipe, which can be opened when the air pressure on both sides of the pressure relief membrane is too uneven, so as to balance the air pressure on both sides. The gasification containing chamber runs through the cooling containing chamber, so that the gasification containing chamber can dissipate heat in the airflow heat dissipation chamber, thereby improving the cooling speed of the alcohol.
[0014] Furthermore, the airflow heat dissipation mechanism includes an airflow heat dissipation chamber, which provides a corresponding channel for air circulation, so that air can pass quickly in the airflow heat dissipation chamber;
[0015] The airflow heat dissipation bin and the cooling storage bin are both fixedly installed with compression baffles, which can reduce the air passing through the airflow heat dissipation bin, accelerate air circulation, and make the pressure on both sides of the coolant uneven, so that the air under the cooling water separation membrane can pass through the cooling water separation membrane, thereby enhancing the heat dissipation capacity of the coolant.
[0016] Furthermore, a dustproof bin is fixedly installed on the lower side of the airflow heat dissipation bin, which can provide a channel for air circulation. An airflow dustproof net is fixedly installed in the dustproof bin, which can block dust in the air, thereby improving the cleanliness level in the airflow heat dissipation bin.
[0017] Furthermore, an airflow temporary storage bin is fixedly installed on the outer side of the airflow heat dissipation bin, which can temporarily accommodate the air, facilitating the installation of the airflow exhaust duct and the airflow motor;
[0018] The airflow temporary storage bin is provided with an airflow discharge pipe, which provides a corresponding channel for the discharge of air, so that the air can be discharged from the airflow discharge pipe with heat;
[0019] An air flow transmission shaft is arranged in the air flow discharge duct, which can drive the air flow fan to rotate, so that the air flow fan draws air in the air flow temporary storage bin.
[0020] Furthermore, an airflow fan is installed on the airflow transmission shaft, which can drive the circulation of air by rotating. A pair of airflow support frames are installed between the airflow transmission shaft and the airflow discharge pipe, which can improve the balance of the airflow transmission shaft and reduce the probability of the airflow transmission shaft tilting.
[0021] The airflow temporary storage bin is provided with an airflow motor, which can drive the rotation of the driving wheel and provide corresponding power for the rotation of the driving wheel.
[0022] Furthermore, the airflow motor and the airflow exhaust pipe are both arranged through the airflow temporary retention bin, and a driving wheel is installed on the airflow motor, which can drive the rotation of the driven wheel through a transmission belt, thereby driving the rotation of the airflow transmission shaft, and a driven wheel is installed on the airflow transmission shaft, and a transmission belt is installed between the driving wheel and the driven wheel.
[0023] The injection mold for a carbon fiber composite material impeller proposed by the present invention adopting the above structure can quickly cool the injection mold, shortening the time required for cooling. After demolding, the possibility of deformation of the carbon fiber composite material impeller is reduced. At the same time, the injection molding time of each impeller is shortened, thereby improving the efficiency of injection molding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0035] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0036] like Figures 1 to 8 As shown, this embodiment provides an injection mold for a carbon fiber composite material impeller, comprising: a mold body 1, an injection cooling mechanism 2 and an airflow heat dissipation mechanism 3.
[0037] like Figures 1 to 7 As shown, an injection molding cooling mechanism 2 is fixedly installed on one side of the mold body 1. The injection molding cooling mechanism 2 includes a cooling accommodating chamber 201, which can form a space with the cooling water separation membrane 202 to accommodate the coolant and absorb the heat on the mold body 1, so that the mold body 1 can quickly dissipate heat.
[0038] Among them, a cooling water separation membrane 202 is fixedly installed in the cooling storage chamber 201, which can carry the coolant and allow a small amount of air to circulate. When the air enters the coolant, bubbles are formed. The low-temperature bubbles will quickly absorb the heat in the coolant and be discharged with the airflow.
[0039] In addition, a number of evenly distributed vaporization containing chambers 203 are fixedly installed in the cooling containing chamber 201, which can contain alcohol 204. The vaporization containing chamber 203 is provided with alcohol 204, which can quickly absorb the heat in the coolant and vaporize. After being cooled by the air flowing rapidly in the airflow heat dissipation chamber 301, it returns to the liquid state and absorbs the heat in the coolant again.
[0040] like Figures 1 to 6 As shown, a support filter 205 is provided on the lower side of the cooling water-dividing membrane 202 , which can support the cooling water-dividing membrane 202 without hindering the circulation of air. The support filter 205 is fixedly connected to the cooling containing chamber 201 .
[0041] like Figures 1 to 7 As shown, a number of evenly distributed heat dissipating fins 206 are provided in the cooling storage bin 201, which can absorb the heat on the surface of the mold body 1 and transfer the heat to the coolant contained in the cooling storage bin 201, so that the heat in the mold body 1 can be quickly absorbed.
[0042] The heat dissipation fins 206 are fixedly connected to the mold body 1 , which improves the stability of the heat dissipation fins 206 , reduces the probability of the heat dissipation of the heat dissipation fins 206 , and improves the heat dissipation effect of the heat dissipation fins 206 .
[0043] like Figures 1 to 5 As shown, a pressure relief pipe 207 is provided in the cooling storage chamber 201. When the airflow transmission shaft 307 rotates too fast, that is, the air pressure above the coolant is too low, the pressure relief membrane 208 will open, so that the pressure relief pipe 207 connects the upper and lower sides of the coolant, reducing the possibility of overload and damage to the airflow motor 310.
[0044] In addition, the pressure relief pipe 207 passes through the cooling water separation membrane 202, the supporting filter 205 and the heat dissipation fins 206, so that air can pass through the cooling water separation membrane 202 and the supporting filter 205. At the same time, the heat dissipation fins 206 can improve the balance of the pressure relief pipe 207 and reduce the probability of the pressure relief pipe 207 tilting.
[0045] like Figures 1 to 6 As shown, a pressure relief membrane 208 is fixedly installed in the pressure relief pipe 207, which can be opened when the air pressure on both sides of the pressure relief membrane 208 is too uneven, and can balance the air pressure on both sides. The gasification containing chamber 203 runs through the cooling containing chamber 201, so that the gasification containing chamber 203 can dissipate heat in the airflow heat dissipation chamber 301, thereby improving the cooling speed of the alcohol 204.
[0046] like Figures 1 to 8 As shown, an airflow heat dissipation mechanism 3 is installed on one side of the cooling storage bin 201 . The airflow heat dissipation mechanism 3 includes an airflow heat dissipation bin 301 , which provides a corresponding channel for air circulation so that air can pass quickly in the airflow heat dissipation bin 301 .
[0047] Among them, compression baffles 302 are fixedly installed on the airflow heat dissipation chamber 301 and the cooling containing chamber 201, which can reduce the air passing through the airflow heat dissipation chamber 301 and accelerate the air circulation. At the same time, it can make the pressure on both sides of the coolant uneven, so that the air under the cooling water separation membrane 202 can pass through the cooling water separation membrane 202, thereby enhancing the heat dissipation capacity of the coolant.
[0048] like Figures 1 to 6 As shown, a dustproof bin 303 is fixedly installed on the lower side of the airflow heat dissipation bin 301, which can provide a channel for the circulation of air. An airflow dustproof net 304 is fixedly installed in the dustproof bin 303, which can block dust in the air and improve the cleanliness level in the airflow heat dissipation bin 301.
[0049] like Figures 1 to 4 As shown, an airflow temporary storage bin 305 is fixedly installed on the outer side of the airflow heat dissipation bin 301 , which can temporarily accommodate air and facilitate the installation of the airflow exhaust duct 306 and the airflow motor 310 .
[0050] In addition, an airflow discharge duct 306 is installed on the airflow temporary storage bin 305 to provide a corresponding channel for the discharge of air, so that the air can carry heat and be discharged from the airflow discharge duct 306 .
[0051] In addition, an air flow transmission shaft 307 is provided in the air flow discharge duct 306 , which can drive the air flow fan 308 to rotate, so that the air flow fan 308 draws air in the air flow temporary storage bin 305 .
[0052] like Figures 1 to 5 As shown, an airflow fan 308 is installed on the airflow transmission shaft 307, which can drive the circulation of air by rotating. A pair of airflow support frames 309 are installed between the airflow transmission shaft 307 and the airflow exhaust duct 306, which can improve the balance of the airflow transmission shaft 307 and reduce the probability of the airflow transmission shaft 307 tilting.
[0053] The airflow temporary storage bin 305 is provided with an airflow motor 310 , which can drive the rotation of the driving wheel 311 and provide corresponding power for the rotation of the driving wheel 311 .
[0054] like Figures 1 to 6 As shown, the airflow motor 310 and the airflow exhaust pipe 306 are both set through the airflow temporary storage bin 305. The airflow motor 310 is equipped with a driving wheel 311, which can drive the rotation of the driven wheel 312 through the transmission belt 313, and then drive the rotation of the airflow transmission shaft 307. The airflow transmission shaft 307 is equipped with a driven wheel 312, and a transmission belt 313 is installed between the driving wheel 311 and the driven wheel 312.
[0055] During specific use, when the mold body 1 needs to dissipate heat, turn on the airflow motor 310 to allow the air at the bottom of the cooling storage bin 201 to partially enter the cooling storage bin 201 through the cooling water separation membrane 202, and partially enter the airflow heat dissipation bin 301. The coolant in the cooling storage bin 201 will quickly absorb the heat in the mold body 1, absorb the heat through the alcohol 204, and vaporize it. The high-speed circulating air in the airflow heat dissipation bin 301 will carry the heat out, and the vaporization storage bin 203 will liquefy and circulate. The air entering the cooling storage bin 201 through the cooling water separation membrane 202 will also absorb the heat in the cooling water separation membrane 202 and be discharged through the airflow fan 308. When the air pressure on both sides of the pressure relief membrane 208 is too uneven, the pressure relief membrane 208 is opened to balance the air pressure on both sides.
