Description

Technical Field

[0001] The invention relates to the technical field of moulds, in particular to an adjustable mould for forming centrifugal fan blades. Background Art

[0002] Centrifugal fan blade forming mold is a tool used to manufacture centrifugal fan blades. Its main function is to process raw materials into blades of required shape and size.

[0003] After searching, the Chinese patent with announcement number CN217492404U discloses a riveted fan blade production mold, which relates to the field of fans. The above technical solution includes an upper assembly mold and a lower assembly mold. The upper assembly mold includes a top plate, and a movable upper mold is arranged below the top plate; the lower assembly mold includes a bottom plate and a limit block on the bottom plate, and a die jacket is arranged above the bottom plate. A movable lower mold is installed in the die jacket. The structure of the movable lower mold is the same as that of the blade to be formed. The above technical solution ensures the forming accuracy of the riveted blades. Each blade is individually placed in the die jacket for shaping. The forming area dimensions of the die jacket and the movable lower mold are completely matched with the blade to be processed. The blade is accurately positioned and does not shift during molding. An elastic rod is arranged at the center of the die jacket to eject the movable lower mold, which facilitates the demolding of the formed blade. However, the above technical solution still has the following shortcomings when used in practice:

[0004] The above technical solution does not have the function of cooling the mold. During the stamping process of the fan blades, the metal sheet raw materials are stamped by the stamping mold at a high frequency.

[0061] 1. During the stamping process, the bottom die and top die may generate high temperatures due to friction. Using low-temperature gas to cool down the die can effectively prevent overheating of the die. Overheating may cause damage, deformation or reduce the service life of the die. Therefore, cooling down the die can improve its stability and durability. Using low-temperature gas to cool down the die can quickly and effectively reduce the die temperature and shorten the cooling time. By cooling down, the die can be kept at an appropriate temperature during the stamping process, which helps to improve the precision and surface quality of the stamped parts.

[0062] 2. By setting up the first control component and the second control component, under the action of the first control component and the second control component, the first and second air injection pipes can store gas when the top mold descends and spray gas when the top mold ascends, thereby accurately controlling the injection timing of the low-temperature gas, so that the low-temperature gas can cool the bottom mold and the top mold after the stamping action is completed. This design can avoid the phenomenon of gas waste;

[0063] 3. The design of the winding wheel, rotating shaft and stirring element allows the coolant to flow evenly and comprehensively inside the second mounting block. The forward and reverse rotation of the rotating shaft enables the stirring element to continuously stir the coolant. During the high-frequency stamping process, this design allows the coolant to cool the mold while continuously stirring, maintaining a stable cooling effect. This helps ensure that the coolant can cover the cooling area of ​​the semiconductor refrigeration chip and improve the cooling effect.

[0064] 4. By fixing the metal sheet before the upper and lower molds are pressed together, the position of the metal sheet can be more stably controlled during the stamping process, which helps to reduce the error caused by the position change of the metal sheet, which helps to improve the consistency and quality of the product.

[0084] The second mounting block 6 is provided with a stirring assembly, which includes: a rotating shaft 131, one end of which is rotatably mounted on the inner surface of the second mounting block 6, and the other end extends to the outside of the second mounting block 6; a winding wheel 132, which is fixed to one end of the rotating shaft 131 located outside the second mounting block 6; a spring 133, one end of which is connected to the rotating shaft 131, and the other end is connected to the second mounting block 6; a rope 134, one end of which is fixed to the winding wheel 132. The stirring member 135 is fixedly mounted on the rotating shaft 131 and immersed in the coolant. During the high-frequency stamping process, the rotating shaft 131 can continuously rotate forward and reverse, and the stirring member 135 on the rotating shaft 131 can continuously stir the coolant, so that the coolant flows inside the second mounting block 6. This design is conducive to the uniform and comprehensive flow of the coolant to the cooling area of ​​the semiconductor refrigeration plate 86.

[0085] The specific working principle of the present invention is as follows:

[0086] In actual use, the adjustable mold for forming centrifugal fan blades proposed by the present invention is initially separated from the bottom mold 3 and the top mold 4. In this state, the first air holes 95 are aligned with the first openings 96, the second air holes 104 are aligned with the second openings 105, the connecting plate 111 and the inclined surfaces of the extrusion block 113 do not contact each other, the gear 121 is located at the top end of the rack 123, and the four sliding plugs 72 are respectively located at the bottom ends of the four sealing outer cylinders 71.

[0087] During the stamping process of the centrifugal fan blades, the staff first inserts the metal raw material sheet between the bottom die 3 and the top die 4, and then the top plate 2 drives the top die 4 to move downward, and the metal raw material sheet is stamped through the pressing action of the bottom die 3 and the top die 4, thereby obtaining the centrifugal fan blades. Specifically, in the process of the top plate 2 driving the top die 4 to move downward, the bottom ends of the four connecting rods 73 first contact the metal raw material sheet and press the metal raw material sheet onto the bottom die 3, which enables the four connecting rods 73 to jointly press the metal raw material sheet, playing a role in pressing and fixing the metal raw material sheet, thereby ensuring the stability of the metal raw material sheet during the stamping process. To prevent the metal raw material plates from shaking and deflecting, as the top plate 2 continues to move downward, the four sealed outer cylinders 71 will continue to move downward, causing the four sealed outer cylinders 71 and the four connecting rods 73 to move relative to each other, and the four sliding plugs 72 will slide inside the four sealed outer cylinders 71. During this process, the four sliding plugs 72 can press the air inside the four sealed outer cylinders 71 into the cooling pipe 81 through the four connecting pipes 82. When the gas enters the cooling pipe 81, the air inside the cooling pipe 81 will enter the outlet pipe 83 and enter the first injection pipe 92 and the second injection pipe 102 through the two branch pipes on the outlet pipe 83.

[0088] During the downward movement of the top plate 2, the first control assembly and the second control assembly will also operate accordingly. For the first control assembly, when the top plate 2 moves downward, the extrusion block 113 will move downward accordingly. Since the extrusion block 113 is located at a position opposite to the sliding plate 112, when the extrusion block 113 moves downward, its inclined surface will contact the sliding plate 112 and squeeze the sliding plate 112. When the inclined surface of the sliding plate 112 is squeezed, in the vertical direction, the pressure applied by the extrusion block 113 to the sliding plate 112 is not enough to overcome the elastic force applied by the third spring 114 to the sliding plate 112. At this time, the sliding plate 112 cannot move downward, but will drive the sliding sleeve 93 to move through the connecting plate 111. When the sliding sleeve 93 moves, the first air holes 95 and the first openings 96 will be staggered with each other. At this time, the sliding sleeve 93 can move the first air holes 95 and the first openings 96. The openings 96 are blocked, and the gas entering the first air injection pipe 92 cannot be ejected through the first openings 96. Further, the air pressure inside the first air injection pipe 92 gradually increases. As the top plate 2 continues to move downward, the extrusion block 113 will continue to squeeze the sliding plate 112. Since the sliding plate 112 cannot move along the first air injection pipe 92 at this time, the sliding plate 112 will move downward and squeeze the third spring 114. The downward movement of the sliding plate 112 can not only ensure that the top plate 2 can move downward smoothly and avoid movement interference between the sliding plate 112 and the top plate 2, but also, the sliding plate 112 is located near the extrusion block 113, which makes it possible for the sliding sleeve 93 to move accordingly in the early stage of the downward movement of the top plate 2, so that sufficient gas can be accumulated inside the first air injection pipe 92 to ensure the subsequent gas cooling effect on the bottom mold 3;

[0089] For the second control component, when the top plate 2 moves downward, the rack 123 can be driven downward by the vertical plate 122. When the rack 123 moves, the gear 121 can be driven to rotate, so that the rotating sleeve 103 rotates. When the gear 121 and the rack 123 are separated from each other, the rotating sleeve 103 stops rotating. At this time, the second air holes 104 and the second openings 105 are staggered with each other. The rotating sleeve 103 can block the second openings 105, and the gas entering the second injection pipe 102 cannot be ejected through the second openings 105, so that the internal air pressure of the second injection pipe 102 gradually increases. In addition, a cooling component is provided in the second mounting block 6, and the cooling pipe 81 is immersed in coolant. This design enables the low-temperature coolant to cool the gas inside the cooling pipe 81, thereby making the gas entering the first injection pipe 92 and the second injection pipe 102 have a lower temperature, thereby ensuring the subsequent gas cooling effect on the bottom mold 3;

[0090] After the bottom mold 3 and the top mold 4 are pressed together, the stamping and shaping of the fan blades are completed, and then the top plate 2 drives the top mold 4 to move up and reset. During this process, the four sliding plugs 72 will reset under the action of the corresponding first springs 74. When the four sliding plugs 72 are reset, they can perform a pumping action and jointly extract the gas in the cooling pipe 81. When the gas in the cooling pipe 81 is extracted, the gas in the external environment will be replenished into the interior of the cooling pipe 81 through the air inlet pipe 84, which is convenient for cooling during the next stamping. In addition, during the reset of the top plate 2, the extrusion block 113 will separate from the sliding plate 112. When the two are completely separated, the sliding sleeve 93 will reset under the action of the second spring 94, so that the first air holes 95 are aligned one by one with the first openings 96. In this case, the low-temperature gas accumulated in the first injection pipe 92 will pass through the overlapping first air holes 95 The low-temperature gas accumulated in the second air injection pipe 102 will be ejected through the overlapping second air holes 104 and the second openings 105, and will be ejected toward the top mold 4, thereby cooling the top mold 4. In summary, during a stamping operation of the bottom mold 3 and the top mold 4, the low-temperature gas can be blown to cool the bottom mold 3 and the top mold 4 to prevent overheating of the bottom mold 3 and the top mold 4.

[0091] The interior of the second mounting block 6 is equipped with a semiconductor refrigeration sheet 86. When the mold is in use, the semiconductor refrigeration sheet 86 is powered on to cool the coolant in the second mounting block 6 to ensure the cooling effect of the coolant on the gas in the cooling tube 81. In addition, a stirring assembly is also provided on the second mounting block 6. One end of the rope 134 on the winding wheel 132 is fixed to the frame of the stamping equipment. When the top plate 2 drives the second mounting block 6 to move downward, the winding wheel 132 will also move downward. Since one end of the rope 134 is in a fixed state, the winding wheel 132 can drive the rotating shaft 131 to rotate under the action of the rope 134, and the top plate 2 drives the second mounting block 6 to move downward. When the plate 2 drives the second mounting block 6 to move upward, the winding wheel 132 will be reset under the action of the clockwork spring 133, which makes the rotating shaft 131 rotate in the opposite direction. Therefore, during the high-frequency stamping process, the rotating shaft 131 can continuously rotate forward and reverse, and the stirring member 135 on the rotating shaft 131 can continuously stir the coolant so that the coolant flows inside the second mounting block 6. This design is conducive to the uniform and comprehensive flow of the coolant to the cooling area of ​​the semiconductor refrigeration plate 86, so that the semiconductor refrigeration plate 86 can comprehensively cool the coolant, thereby ensuring the cooling effect of the low-temperature gas on the bottom mold 3 and the top mold 4.
