Description
Technical Field
[0001] The invention relates to the technical field of injection molding molds, in particular to an injection mold for a curved fluid impeller. Background Art
[0002] With the development of intelligent manufacturing technology, the intelligence and automation level of injection molds will continue to improve. By introducing advanced sensors, control systems, robots and other equipment, the injection molding process can be automated and intelligently managed, improving production efficiency and impeller quality. As the requirements for impeller performance continue to increase, the precision and efficiency of injection molds will become a future development trend. By optimizing mold design, improving the injection molding process, and adopting high-performance materials, the dimensional and shape accuracy of impellers can be improved, while reducing production costs and cycle times.
[0003] The prior art also has the following defects during use:
[0004] When the injection mold in the prior art is performing injection molding, the injection molded impeller is usually not easy to remove after the injection molding is completed, and a large degree and range of demolding work is required, which wastes a lot of time for demolding and installing the mold. When the curved impeller is taking out the material, due to the difficulty of demolding the curved surface, the current technology is provided with a sliding open fluid impeller blade. However, after the fluid impeller blade is opened, the impeller is still close to the base surface. Because the outer wall is relatively weak, there is no good material taking point, which still makes it difficult to take out the material, and the efficiency of injection molding cannot be improved.
[0005] In view of this, we propose a curved fluid impeller injection mold to solve the existing problems. Summary of the Invention

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example
[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention proposes a curved fluid impeller injection mold, including an injection cylinder 8 and an injection shell 1, the injection shell 1 is equipped with an injection cylinder 8, the upper end of the injection cylinder 8 is provided with a rotating gear 7, one side of the rotating gear 7 is connected to a telescopic control member 3, the injection cylinder 8 is fixedly connected downwardly to a rotating frame 9 and a rotating disk 10, the rotating disk 10 is provided with multiple groups of arc grooves, the arc grooves are provided with multiple groups of cylindrical heads 11, the lower end of the rotating disk 10 is provided with an injection layer 12, the injection layer 12 is provided with multiple groups of chutes 15, the chutes 15 are provided with fluid impeller blades 14, and the upper ends of the fluid impeller blades 14 are fixedly connected to the cylindrical heads 11;
[0031] The telescopic control member 3 controls the rotation of the rotating gear 7 after the injection molding is completed, thereby driving the rotating disk 10 at the lower end to move. During the movement of the rotating disk 10, the pressure of the inner wall of the arc groove is applied, thereby driving the cylindrical head 11 to slide in the arc groove. During the movement of the cylindrical head 11, the fluid impeller blades 14 can move in the chute 15, thereby dispersing the fluid impeller blades 14 used for injection molding.
[0032] A bottom layer 17 is provided at the lower end of the injection molding layer 12. A fixing member 20 is fixed at the center of the bottom layer 17. A motion groove 19 is provided on the upper side of the fixing member 20. A threaded rotation groove 24 is provided at the lower end of the rotating frame 9. A moving member 23 is connected to the threaded rotation groove 24. Both sides of the upper end of the moving member 23 are connected to an adjustment rod 21. One end of the adjustment rod 21 is connected to the moving member 23, and the other end of the adjustment rod 21 is connected to a moving block 22. The moving block 22 is slidably connected in the motion groove 19. The upper end of the moving block 22 is connected to the top module 18.
[0033] While the rotating gear 7 rotates, the rotating frame 9 and the connection between the threaded rotating groove 24 and the threaded outer wall allow the entire moving part 23 to move downward, and through the action of the moving groove 19 and the moving block 22, the entire body can form a base mechanism that is convenient for taking out the mold after moving to the lower end. The entire base is mainly divided into movable blocks 22 that can move on both sides and a fixed base. The movable block 22 moves inward during the movement, which can leave space for the upper end to take out the material.
[0034] The telescopic control member 3 drives the rotating gear 7 to rotate, so that the multiple arc grooves drive the corresponding multiple fluid impeller blades 14 to slide synchronously along the curvature of the arc groove to slide outward so that the impeller 13 is separated from the multiple fluid impeller blades 14. At the same time, the multiple moving blocks 22 slide inward to separate the inner wall of the impeller 13 from the moving blocks 22 to create a picking space under the impeller 13.
[0035] When the telescopic control member 3 drives the rotating gear 7 to move, the fluid impeller blade 14 opens outward, and when the base of the injection mold moves downward, the moving blocks 22 on both sides of the base will move inward. Because the surface of the product is relatively weak and fits on the molding base, a certain amount of space is required for taking out the parts to facilitate the application of force.
[0036] Furthermore, the telescopic control member 3 includes a control motor 2 and a rack 6. The control motor 2 is installed at the outer end of the injection molded shell 1, and the control motor 2 passes through the injection molded shell 1 and is inwardly connected to the rack 6. The rotating gear 7 is meshed with the rack 6.
[0037] The control motor 2 can control the back-and-forth movement of the rack 6 , thereby controlling the movement direction of the rotating gear 7 through the movement of the rack 6 .
[0038] Furthermore, a base 16 is provided under the bottom layer 17 . A limiting groove 25 is provided at the center of the base 16 , and the moving member 23 is installed on the base 16 through the limiting groove 25 .
[0039] The position of the moving member 23 is limited by the base 16 to prevent the moving member 23 from rotating along with the thread rotation groove 24 when the moving member 23 is acted upon by the thread rotation groove 24 , thereby ensuring that the moving member 23 moves up and down under the action of the thread rotation groove 24 .
[0040] Furthermore, a threaded outer wall 26 is provided on the surface of the moving member 23 , and the moving member 23 is connected to the rotating frame 9 via the threaded outer wall 26 .
[0041] The rotating frame 9 as a whole can rotate along with the rotating disk 10 and the rotating gear 7 . During the rotation process, the rotating frame 9 can drive the moving member 23 to move up and down under the action of the threaded outer wall 26 and the threaded rotating groove 24 .
[0042] Furthermore, a ball bearing is provided at the lower end of the moving block 22 , and the moving block 22 is slidably connected to the moving groove 19 via the ball bearing, and the moving groove 19 as a whole presents a certain tilt angle.
[0043] The moving blocks 22 move to a certain extent in the moving slots 19 , so that the entire base module moves upward or downward, and the individual moving blocks 22 on both sides of the base module also move sideways.
[0044] Furthermore, the top module 18 and the moving block 22 will form a complete mold base after moving upward. The closed fluid impeller blade 14, the top module 18 and the moving block 22 can form a complete injection molding cavity in the injection layer 12, and the complete injection molding cavity is used to store the impeller 13.
[0045] The top module 18 is the top of the integral injection molding base. The moving blocks 22 installed on both sides of the injection molding base will move along with the movement of the injection molding base. When the moving blocks 22 move to both sides and fit the top module 18 and the remaining injection molding bases into a completed injection mold, they serve as the base for injection molding. After the injection molding is completed, the base begins to move downward, so that the moving blocks 22 will also move inward to form a gap for convenient mold removal.
[0046] Furthermore, the upper end of the rotating frame 9 is fixedly mounted to the injection cylinder 8 , the lower end of the rotating frame 9 is located at the lower end of the bottom layer 17 , and the lower end of the rotating frame 9 is connected to the moving member 23 via a threaded rotating groove 24 .
[0047] The rotating frame 9 connects the upper and lower parts and transmits the motion state of the upper end to the lower end, thereby controlling the movement of the moving member 23 .
[0048] Furthermore, an injection molding blanking head 4 is provided on the top of the injection molding shell 1 , and an injection molding blanking pipe 5 is connected to the lower end of the injection molding blanking head 4 . The injection molding blanking pipe 5 passes downward through the injection molding cylinder 8 and the rotating disk 10 and is connected to the injection molding layer 12 .
[0049] The injection molding material can be transported to the lower end through the injection molding discharge head 4, and then flowed into the injection molding cavity after passing through the injection molding cylinder 8 and the rotating disk 10 to realize injection molding.
[0050] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
