Technical Field

[0001] The present application relates to the technical field of metal injection molding, and in particular to a titanium alloy product and a metal injection molding device thereof. Background Art

[0002] Titanium alloy products are various products made from titanium alloys. They have many characteristics such as high strength, low density, excellent corrosion resistance, outstanding high temperature performance and good biocompatibility. In the production process of titanium alloy products, metal injection molding technology is often used. Metal injection molding is a new type of powder metallurgy near-net forming technology that combines modern plastic injection molding technology with traditional powder metallurgy process. Titanium alloy scalpel handles, as a kind of titanium alloy products, are usually produced by metal injection molding. This production method not only gives the titanium alloy scalpel handles the characteristics of firmness and durability, but also effectively reduces the risk of infection during surgery, thereby improving the success rate and safety of the operation.

[0003] In response to the above technical problems, a patent with announcement number CN117862506B discloses a metal powder injection molding machine, including a frame, on which an injection mechanism and a molding mechanism are arranged, the molding mechanism includes a fixed template, a movable template, a separation assembly and a clamping assembly, the fixed template is fixed to the frame, the movable template is movably connected to the frame through a driving member, an injection port and a first mold cavity are arranged on the fixed template, the injection port is communicated with the first mold cavity, a second mold cavity is arranged on the movable template, the second mold cavity is opposite to the first mold cavity, the separation assembly includes a separation plate, a movable part and a push rod, the separation plate is arranged on the outer side of the movable template, the movable part and the push rod are fixed to the separation plate, the movable part passes through the fixed template and the movable template, the moving direction of the movable part is parallel to the moving direction of the movable template, the clamping assembly includes two clamping blocks, the clamping blocks clamp the condensate at the injection port and demold it together with the workpiece, the molding machine provided by the patent avoids pulling between the workpiece and the condensate when demolding, and reduces deformation of the workpiece.

[0004] However, the above technical solution has the following defects: (1) Although the molded workpieces can be demolded, when multiple workpieces are molded continuously, the demolded workpieces may be placed in the same place in a relatively messy state. In some cases, the subsequent processing steps of the workpieces may require a certain number of workpieces to be processed simultaneously or sequentially. At this time, reasonable batching according to the total number of workpieces can ensure the stability and efficiency of the process. When the workpieces are piled together, it is not only difficult to count the total number of workpieces, but also difficult to take out the appropriate number of workpieces, which in turn affects the batching operation of the workpieces. In addition, the surface of the molded workpiece may have defects such as cracks and dents. In order to avoid defective workpieces from being put into subsequent use, workers are usually required to conduct quality inspections by visual means. If the workpieces are placed in the same place in a messy manner, it is not conducive to workers' inspections, and it is easy to miss inspections and confusion. Summary of the invention

[0015] A titanium alloy product is injection molded by the aforementioned injection molding device.

[0016] Compared with the prior art, the beneficial effects of this application are: (1) After the metal powder melt in the molding cavity is formed, the upper mold and the lower mold are driven to separate, and the electric push rod is used to drive the two ejector rods to rise, so that the molded workpiece can be ejected, thereby realizing automatic demolding of the molded workpiece, eliminating the process of manually removing the workpiece from the mold cavity, which is more convenient and labor-saving.

[0017] (2) By using a material receiving mechanism with controllable material discharge amount, after the workpiece is ejected by the ejector, the workpiece can be clamped by two turntables and placed on the placement plate 1 and the placement plate 2, so that multiple workpieces can be neatly arranged and placed on the placement plate 1 and the placement plate 2, and a suitable distance is maintained between each workpiece. At this time, the worker can count the total number of workpieces, and because the workpieces are neatly arranged, the counting process is not prone to errors. After the counting is completed, according to the number of workpieces that need to be collected at one time, the turntable is driven to be placed between the two workpieces, and then the collection container is placed at the ends of the placement plate 1 and the placement plate 2, and the turntable is driven to move horizontally to push the workpiece. Because the workpieces are arranged, multiple workpieces will fall from the ends of the placement plate 1 and the placement plate 2 to the collection container. The workpieces are collected in batches by placing them in the collection container and repeating the above operation. The number of workpieces in each batch is controllable, so that a suitable number of workpieces can be transferred to the subsequent processing steps, thereby ensuring the stability and efficiency of the workpieces in the subsequent processing steps. In addition, since the workpieces are neatly arranged on the placement plate 1 and the placement plate 2, the workers can check the surface quality of the workpieces in sequence and in an orderly manner to avoid missed inspections and confusion. In addition, when it is necessary to inspect the other side of the workpiece, the workpiece can be clamped in sequence by the turntable, and then the turntable can be driven to rotate so that the other side of the workpiece faces upwards. At this time, the workers can inspect the other side of the workpiece, thereby ensuring the comprehensiveness of the inspection. In addition, when the workers find a workpiece with defects on the surface, they can first inspect the position where the defective workpiece is located. The L-shaped plate is driven to move horizontally, and the push block is aligned with the defective workpiece in turn. Then the push block is driven to move and pass through the groove of the placement plate one, so that the workpiece can be pushed off the placement plate two, thereby removing the workpiece with surface defects from the remaining workpieces, avoiding the situation where the defective workpiece is mixed with the remaining workpieces when the workpieces are collected and enters the subsequent processing steps. Moreover, each time a workpiece is placed at the designated position by the turntable, the pressure rod is driven to move horizontally. When the pressure rod moves horizontally, its end will contact the inclined surface at the bottom of the spacer block, so that the spacer block moves upward, and the above operation is repeated. As the number of workpieces on the placement plate one and the placement plate two increases, more spacers move upward, so that each workpiece is placed between the two spacers. At this time, no matter the workpiece is turned over or the equipment is vibrated, the workpiece will only move between the two spacers, and as long as the workpiece is between the two spacers, the push block can be aligned with the workpiece, and when the workpiece needs to be collected, multiple spacers are reset under the action of the spring, and the spacing between adjacent workpieces must not be less than the thickness of the spacer. The turntable can also be extended between the two spacers to push the workpiece, thereby avoiding the workpieces on the placement plate 1 and the placement plate 2 from deviating from the initial position due to factors such as turning over and vibration, resulting in the inability to perform defective workpiece removal and workpiece collection operations normally. In addition, each spacer is printed with a number. When workers check the workpiece, they can record the number to record the position of the defective workpiece and enter the number into the controller.To achieve accurate removal of defective workpieces.

[0038] One end of the side adjustment plate 33 is fixedly connected to the motor 5 35 , and the output end of the motor 5 35 is fixedly connected to the turntable 34 .

[0039] A plurality of spacers 9 are slidably connected to one side of the placement plate 13, and the spacers 9 can slide in the gap between the placement plate 13 and the placement plate 2 15. A spring 23 is fixedly connected to one side of the spacer 9, and the upper end of the spring 23 is fixedly connected to the placement plate 13. A slide rod 2 10 is fixedly connected to one side of the placement plate 13, and the slide rod 2 10 is slidably connected to a pressure rod 7.

[0042] Specifically, although the existing metal powder injection molding machine can demold the molded workpiece during use, when multiple workpieces are continuously molded, the demolded workpieces may be placed in the same place in a relatively messy state. In some cases, the subsequent processing steps of the workpieces may require a certain number of workpieces to be processed simultaneously or sequentially. At this time, reasonable batching according to the total number of workpieces can ensure the stability and efficiency of the process. When the workpieces are piled together, it is not only difficult to count the total number of workpieces, but also difficult to take out a suitable number of workpieces, which further affects the batching operation of the workpieces. In addition, the surface of the molded workpiece may have defects such as cracks and dents. In order to avoid defective workpieces from being put into subsequent use, workers are usually required to conduct quality inspections by visual means. If the workpieces are placed in the same place in a messy manner, it is not conducive to workers' inspections, and missed inspections and confusion are prone to occur.

[0043] Therefore, in order to solve the above problems, when the present embodiment is in use, the formed workpiece in the present application is the main body of the titanium alloy scalpel handle; when the workpiece is ejected by the ejector rod 24, the motor 2 16 drives the threaded rod 2 17 to rotate, so that the connecting rod 8 can be moved horizontally until the workpiece is between the two turntables 34; then the motor 4 31 drives the threaded rod 4 32 to rotate, so that the threaded block 30 rises. When the threaded block 30 rises, it can drive the connecting rods 29 on both sides to rotate at the same time, and the two adjustment plates 33 slide in different directions at the same time, so that the two turntables 34 can be close to each other to clamp the workpiece, and then the connecting rod 8 continues to move horizontally, so that the workpiece is above the placement plate 1 13 and the placement plate 2 15, and the above operation is repeated, so that multiple workpieces can be neatly arranged and placed on the placement plate 1 13 and the placement plate 2 15, and each workpiece is kept at a suitable distance, and the turntable 34 can extend between the two workpieces; when all workpieces are placed above the placement plate 1 13 and the placement plate 2 15 After that, at this time, the worker can count the total number of workpieces, and since the workpieces are neatly arranged, the counting process is not prone to errors. After the counting is completed, according to the number of workpieces that need to be collected at one time, the turntable 34 is driven to be placed between two workpieces, and then the collection container is placed at the ends of the placement plate 13 and the placement plate 2 15, and the turntable 34 is driven to move horizontally to push the workpieces. Since the workpieces are arranged, multiple workpieces will fall from the ends of the placement plate 13 and the placement plate 2 15 into the collection container at the same time. By repeating the above operation, the workpieces can be collected in batches, and the number of workpieces in each batch can be controlled, so that the appropriate number of workpieces can be transferred to the subsequent processing steps, thereby ensuring the stability and efficiency of the workpieces in the subsequent processes. In addition, when the workpiece is pushed by the turntable 34, the placement plate 13 and the baffle 14 will limit the two ends of the workpiece, so the workpiece will not deviate from the placement plate 13 and the placement plate 2 15.

[0044] Furthermore, since the workpieces are neatly arranged on the placement plate 1 13 and the placement plate 2 15, the workers can check the surface quality of the workpieces in sequence and in an orderly manner to avoid missed inspections and confusion. Furthermore, since the other side of the workpiece is in contact with the surfaces of the placement plate 1 13 and the placement plate 2 15, it is not easy for the workers to observe the other side of the workpiece, which affects the comprehensiveness of the inspection. Therefore, in order to solve this problem, when it is necessary to inspect the other side of the workpiece, the workpieces can be clamped in sequence by the turntable 34, and then the turntable 34 can be driven to rotate by the motor 5 35 to flip the workpiece so that the other side faces upward. At this time, the workers can check the other side of the workpiece, thereby ensuring the comprehensiveness of the inspection. Furthermore, if a defective workpiece is between the workpieces, when the turntable 34 pushes the workpiece to unload, the defective workpiece will be mixed with the non-defective workpiece, resulting in a defective workpiece. The defective workpieces enter the subsequent processing procedures, and it is also quite laborious for workers to manually pick out the defective workpieces one by one. Therefore, in order to solve this problem, when the workers find the workpieces with defects on the surface, they can first record the position of the defective workpieces. When all the workpieces are checked, the electric push rod three 36 can be used to drive the baffle 14 to slide downward until the baffle 14 no longer limits the workpieces. At this time, the motor three 20 can be used to drive the threaded rod three 21 to rotate, so that the L-shaped plate 22 moves horizontally, so that the push block 25 is aligned with the defective workpiece in turn, and then the electric push rod one 18 is used to drive the push block 25 to move and pass through the groove of the placement plate one 13, so that the workpiece can be pushed off the placement plate two 15, so that the workpiece with defects on the surface can be removed from the other workpieces, avoiding the situation where the defective workpieces are mixed with the other workpieces when the workpieces are collected and enter the subsequent processing procedures.

[0045] In the above, since the workpiece will be flipped when it is placed on the placement plate 13 and the placement plate 2 15, the workpiece may deviate from the initial placement position, and the vibration of the equipment and human touch may cause the workpiece on the placement plate 13 and the placement plate 2 15 to deviate. When the workpiece is deviated, the push block 25 may not be able to accurately align with the workpiece, affecting the removal operation of the defective workpiece. At the same time, the turntable 34 may not be able to push the workpiece normally due to the small spacing between the workpieces. Therefore, in order to solve the above problems, every time a workpiece is placed at the specified position by the turntable 34, the motor 12 will drive the threaded rod 11 to rotate, so that the pressure rod 7 moves horizontally. When the pressure rod 7 moves horizontally, its end will contact the inclined surface at the bottom of the spacer block 9, so that the spacer block 9 moves upward, the spring 23 is compressed, and then the above operation is repeated. As the number of workpieces on the placement plate 13 and the placement plate 2 15 increases, more and more spacers 9 move upward. When the workpiece is moved, each workpiece can be placed between the two spacer blocks 9. At this time, no matter whether the workpiece is turned over or the equipment is vibrated, the workpiece will only move between the two spacer blocks 9, and as long as the workpiece is between the two spacer blocks 9, the push block 25 can be aligned with the workpiece, and when it is necessary to collect the workpiece, multiple spacer blocks 9 are reset under the action of the spring 23, and the spacing between adjacent workpieces must not be less than the thickness of the spacer block 9. The turntable 34 can also be extended between the two spacer blocks 9 to push the workpiece, thereby avoiding the workpieces on the placement plate 1 13 and the placement plate 2 15 from deviating from the initial position due to factors such as turning over and vibration, resulting in the inability to perform defective workpiece removal and workpiece collection operations normally. In addition, each spacer block 9 is printed with a number. When workers check the workpiece, they can record the position of the defective workpiece by recording the number, and enter the number into the controller to achieve accurate pushing out of the defective workpiece.

[0046] A titanium alloy product is injection molded by the aforementioned injection molding device.

[0047] The working principle of the present application is as follows: adding molten metal powder into the injection molding machine 3, and then using the hydraulic cylinder 4 to drive the upper mold 37 to descend so that the upper mold 37 and the lower mold 5 fit together. At this time, the upper mold 37, the lower mold 5, and the ejector rod 24 form a complete molding cavity, and then using the injection molding machine 3 to inject the molten metal powder into the molding cavity. The injection molding machine 3 is a prior art and will not be described in detail. After the molten metal powder in the molding cavity is molded, the upper mold 37 is driven to separate from the lower mold 5, and the electric push rod 4 19 is used to drive the two ejector rods 24 to rise, so that the molded workpiece can be ejected, thereby realizing automatic demolding of the molded workpiece, eliminating the process of manually removing the workpiece from the mold cavity, which is more convenient and labor-saving. After the workpiece is ejected by the ejector rod 24, the threaded rod 2 17 is driven by the motor 2 16 By rotating, the connecting rod 8 can be moved horizontally until the workpiece is between the two turntables 34; then the motor 4 31 is used to drive the threaded rod 4 32 to rotate, so that the threaded block 30 rises. When the threaded block 30 rises, it can drive the connecting rods 29 on both sides to rotate at the same time, and the two adjustment plates 33 slide in different directions at the same time, so that the two turntables 34 can be close to each other to clamp the workpiece, and then the connecting rod 8 continues to move horizontally so that the workpiece is above the placement plate 1 13 and the placement plate 2 15. Repeat the above operation to arrange multiple workpieces neatly on the placement plate 1 13 and the placement plate 2 15, and keep a suitable distance between each workpiece, and the turntable 34 can extend between the two workpieces; when all the workpieces are placed above the placement plate 1 13 and the placement plate 2 15, the worker can The total number of workpieces is counted, and since the workpieces are neatly arranged, the counting process is not prone to errors. After the counting is completed, the turntable 34 is driven to be placed between two workpieces according to the number of workpieces that need to be collected at one time, and then a collection container is placed at the ends of the placement plate 13 and the placement plate 2 15, and the turntable 34 is driven to move horizontally to push the workpieces. Since the workpieces are arranged, multiple workpieces will fall from the ends of the placement plate 13 and the placement plate 2 15 into the collection container at the same time. By repeating the above operation, the workpieces can be collected in batches, and the number of workpieces in each batch can be controlled, so that the appropriate number of workpieces can be transferred to the subsequent processing process, thereby ensuring the stability and efficiency of the workpieces in the subsequent process. In addition, when the workpieces are pushed by the turntable 34 , the placement plate 13 and the baffle plate 14 will limit the two ends of the workpiece, so the workpiece will not deviate from the top of the placement plate 13 and the placement plate 2 15; and, since the workpieces are neatly arranged and placed on the placement plate 13 and the placement plate 2 15, the workers can check the surface quality of the workpieces in sequence and in an orderly manner to avoid missed inspections and confusion, and, since the other side of the workpiece is in contact with the surface of the placement plate 13 and the placement plate 2 15, it is not easy for the workers to observe the other side of the workpiece, which affects the comprehensiveness of the inspection. Therefore, in order to solve this problem, when it is necessary to inspect the other side of the workpiece, the workpiece can be clamped in sequence by the turntable 34, and then the turntable 34 can be driven to rotate by the motor 5 35 to flip the workpiece so that the other side faces upward.At this time, the worker can inspect the other side of the workpiece, thereby ensuring the comprehensiveness of the inspection. Moreover, if a defective workpiece is between the workpieces, the defective workpiece will be mixed with the non-defective workpiece when the turntable 34 pushes the workpiece to unload, thereby causing the defective workpiece to enter the subsequent processing procedure. It is also laborious for the worker to manually pick out the defective workpieces one by one. Therefore, in order to solve this problem, when the worker finds a workpiece with defects on the surface, the position of the defective workpiece can be recorded first. When all the workpieces are inspected, the electric push rod 36 can be used to drive the baffle 14 to slide downward until the baffle 14 no longer limits the workpiece. At this time, the motor 3 20 can be used to drive the threaded rod 3 21 to rotate so that L The mold plate 22 moves horizontally, so that the push block 25 is aligned with the defective workpiece in turn, and then the electric push rod 18 is used to drive the push block 25 to move and pass through the groove of the placement plate 13, so that the workpiece can be pushed off the placement plate 2 15, so that the workpiece with surface defects can be removed from the remaining workpieces, avoiding the situation where the defective workpiece is mixed with the remaining workpieces when the workpieces are collected and enters the subsequent processing steps. In the above, since the workpiece will be turned over when placed on the placement plate 13 and the placement plate 2 15, the workpiece may deviate from the initial placement position, and the vibration of the equipment and human touch may cause the workpiece on the placement plate 13 and the placement plate 2 15 to deviate, and when the workpiece is deviated, the push block 25 may not be able to accurately align with the workpiece. The workpieces are placed on the plate 13 and the plate 21 are moved upwards, and the spring 23 is compressed. Then the above operation is repeated. As the number of workpieces on the placing plate 13 and the placing plate 21 increases, more and more spacers 9 move upwards, so that each workpiece is placed between the two spacers 9. At this time, whether the workpiece is turned over or the equipment is vibrated, the workpiece will only be between the two spacers 9. The push block 25 can be aligned with the workpiece as long as the workpiece is between the two spacer blocks 9. When the workpiece needs to be collected, the multiple spacer blocks 9 are reset under the action of the spring 23. The spacing between adjacent workpieces must not be less than the thickness of the spacer blocks 9. The turntable 34 can also extend between the two spacer blocks 9 to push the workpiece, thereby avoiding the workpieces on the placement plate 13 and the placement plate 2 15 from deviating from the initial position due to factors such as flipping and vibration, resulting in the inability to perform the defective workpiece removal operation and the workpiece collection operation normally. In addition, each spacer block 9 is printed with a number. When checking the workpiece, the worker can record the number to record the position of the defective workpiece and input the number into the controller to achieve accurate pushing out of the defective workpiece.
