[0002] In the metal powder injection molding manufacturing process, after the catalytic degreasing process is completed, the material frame and graphite plate carrying the product need to be removed from the relevant equipment and then transferred to the vacuum sintering furnace for subsequent sintering operations.

[0003] Currently, some trolleys use a single lifting adjustment mechanism. However, relying solely on the structural characteristics of this mechanism makes it difficult to accurately and stably adjust the height of the material frame to be level with the inlet of the vacuum sintering furnace. This not only makes the process of pushing graphite plates and products into the material frame of the vacuum sintering furnace less smooth and increases operational difficulty, but may also cause product collisions and damage due to height deviations, affecting production efficiency and product quality.

[0004] Therefore, there is an urgent need for a trolley that can solve the problems of insufficient height adjustment accuracy and poor stability caused by relying on a single lifting adjustment component, so as to achieve smooth alignment between the material frame and the vacuum sintering furnace inlet, improve the smoothness of the transfer operation, reduce the risk of product damage, and ensure production efficiency and product quality.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment provides a trolley used in the metal powder injection molding production process, such as... Figures 1-2 As shown, in this embodiment, the trolley includes a base 1, a lifting unit 2, a carrying unit 3, and a moving unit 4. The lifting unit 2 is mounted on the base 1 and includes a scissor arm assembly 22 and a linear drive component 21. The linear drive component 21 is disposed within the scissor arm assembly 22 and on the base 1. The lower end of the scissor arm assembly 22 is connected to the base 1. The carrying unit 3 is mounted on the lifting unit 2, and the material frame can be placed on the carrying unit 3. The output end of the linear drive component 21 is connected to the carrying unit 3, and the upper end of the scissor arm assembly 22 is connected to the carrying unit 3. The moving unit 4 is disposed at the bottom of the base 1 and is used to move the trolley body. The base 1 serves as the basic support structure for the entire trolley, bearing the lifting unit 2 and all loads above it, and is the installation reference for other units. The carrying unit 3 is the component that directly contacts the material, and its position changes with the movement of the lifting unit 2. The moving unit 4 is used to move the entire trolley body to realize the material transfer function. Traditional scissor lift structures, relying solely on their own weight or manual adjustment, are prone to height deviations due to uneven force distribution. The linear drive component 21 provides stable power output, allowing for precise adjustment of the height of the carrying unit 3 by controlling its extension and retraction. Located within the scissor arm assembly 22, the linear drive component 21 not only provides power but also guides the movement of the scissor arm, preventing swaying caused by lateral forces during lifting. The rigid structure of the scissor arm assembly 22, combined with the stable output of the linear drive component 21, ensures the stability of the carrying unit 3 during lifting and transport, reducing the risk of product damage due to swaying. The linear drive component 21 not only provides stable power for the lifting of the scissor arm assembly 22 but also improves the precision and controllability of height adjustment, avoiding swaying or height deviations that may occur when adjusting solely based on the scissor arm's structure. This ensures a smooth and efficient transport process, reduces the risk of product damage due to improper operation, meets the stringent height alignment requirements of the manufacturing process, and improves the overall smoothness and reliability of operations.

[0045] Optionally, such as Figures 1-2As shown, in this embodiment, the linear drive component 21 includes a worm gear lifting structure 211, which provides stable power for the lifting of the scissor arm assembly 22. Thanks to the self-locking characteristic of the worm gear structure, the load-bearing unit 3 can be stably stopped at any height, avoiding accidental lifting or lowering due to external forces or its own weight. This further improves the accuracy and controllability of height adjustment, effectively preventing swaying or height deviation of the scissor arm during lifting and stopping, ensuring smooth and efficient material transfer, reducing the risk of product damage due to swaying or accidental lifting or lowering, and better adapting to the strict requirements for height alignment in the metal powder injection molding manufacturing process, thus improving the overall smoothness and reliability of the operation. In other embodiments, the worm gear lifting structure 211 can also be replaced by a hydraulic cylinder structure or a linear cylinder structure, etc.

[0046] Preferably, such as Figures 1-2 As shown, in this embodiment, the linear drive component 21 also includes a handwheel 212, which is connected to the worm gear lifting structure 211. Manually rotating the handwheel 212 drives the worm gear structure, thereby raising and lowering the load-bearing unit 3. This ensures the trolley can still operate normally under special circumstances and allows for precise manual control of the lifting amplitude, meeting the stringent height alignment requirements in metal powder injection molding production. Furthermore, the handwheel 212 is intuitive and easy to operate, allowing operators to flexibly adjust it according to actual working conditions, improving the reliability, flexibility, and ease of operation of the trolley and better adapting to the diverse needs of the production process. In other embodiments, the handwheel 212 can be replaced with a servo motor structure or a crank structure, etc.

[0047] Specifically, such as Figures 1-2As shown, in this embodiment, the scissor arm assembly 22 includes a first scissor arm 221, a second scissor arm 222, a central shaft 223, a rotating support 224, a sliding part 225, and a connecting shaft 226. One end of the first scissor arm 221 is connected to the support unit 3, and the other end of the first scissor arm 221 is connected to the base 1. One end of the second scissor arm 222 is connected to the support unit 3, and the other end of the second scissor arm 222 is connected to the base 1. The second scissor arm 222 and the first scissor arm 221 are arranged crosswise and rotatably connected. The first scissor arm 221 and the second scissor arm 222 are rotatably connected by the central shaft 223. The rotating support 224 is respectively installed at the bottom of the support unit 3 and the top of the base 1, and the rotating support 225 is installed on the sliding part 226. On 25, sliding parts 225 are respectively installed on the support unit 3 and the base 1. The first scissor arm 221 is rotatably connected to the rotating support 224 through the connecting shaft 226, and the second scissor arm 222 is rotatably connected to the rotating support 224 through the connecting shaft 226, so that both the first scissor arm 221 and the second scissor arm 222 can rotate relative to the base 1 and the support unit 3. When the linear drive 21 outputs power, it will push or pull the support unit 3. At this time, the first scissor arm 221 and the second scissor arm 222 begin to rotate relative to each other under the connection of the central shaft 223, and the crossing angle gradually changes. The support unit 3 and the base 1 are connected to the first scissor arm 221 and the second scissor arm 222 at both ends through the connecting shaft 226 to the rotating support 224. The first scissor arm 221 The second scissor arm 222 translates along the sliding part 225 installed at the bottom of the support unit 3 and the top of the base 1. As the crossing angle of the scissor arms increases, the support unit 3 is lifted; when the crossing angle decreases, the support unit 3 descends. The central shaft 223 ensures that the two scissor arms rotate flexibly, the connecting shaft 226 ensures reliable rotation between the scissor arms and the rotating support 224, and the sliding part 225 provides stable guidance for the rotating support 224. The components work together to enable the first scissor arm 221 and the second scissor arm 222 to rotate relative to the base 1 and the support unit 3, and to adjust their positions by sliding, ultimately achieving a smooth and precise lifting motion of the support unit 3. The scissor arm assembly 22, through the cross arrangement of the first scissor arm 221 and the second scissor arm 222 and the central shaft 225, achieves this. The rotating connection of component 3, in conjunction with the coordinated action of rotating support 224, sliding part 225, and connecting shaft 226, enables stable lifting and lowering of the load-bearing unit 3. The rotating connection between the two ends of the scissor arm and rotating support 224 via connecting shaft 226, and the movement of rotating support 224 on sliding part 225, allows the scissor arm to rotate and translate flexibly relative to base 1 and load-bearing unit 3. This ensures smooth expansion and contraction of the scissor structure and improves the stability and precision of the lifting and lowering process of load-bearing unit 3. Simultaneously, the rigid connection of each component enhances the overall load-bearing capacity and stability of the structure, effectively preventing swaying or jamming during lifting and lowering. This meets the requirements for material transfer stability in metal powder injection molding production, and the modular design facilitates installation, maintenance, and component replacement.Extend equipment lifespan and improve operational reliability.

[0048] Preferably, such as Figures 1-2 As shown, in this embodiment, the sliding part 225 includes a first slide rail 2251 and a first slider 2252. The first slide rail 2251 is respectively installed on the support unit 3 and the base 1. The first slide rail 2251 extends in the left-right direction. The first slider 2252 is installed on the first slide rail 2251 and can slide along the extension direction of the first slide rail 2251. The upper ends of the first scissor arm 221 and the second scissor arm 222 are both connected to the upper first slider 2252, and the lower ends of the first scissor arm 221 and the second scissor arm 222 are both connected to the lower first slider 2252. The first slider 2252, which connects the upper and lower ends of the first scissor arm 221 and the second scissor arm 222, can slide stably along the slide rail, providing precise guidance for the expansion and contraction of the scissor arm assembly 22. This ensures the consistency of the displacement direction of the scissor arm during lifting and lowering, avoiding jamming or shaking caused by sliding deviation. Furthermore, the smooth cooperation between the slide rail and the slider reduces mechanical wear and improves the smoothness and stability of the scissor arm assembly 22's movement. This, in turn, ensures the accuracy and stability of the lifting of the bearing unit 3, better adapting to the strict requirements for material transfer in metal powder injection molding production. It also extends the service life of the equipment and reduces maintenance costs.

[0049] Preferably, such as Figures 1-2 As shown, in this embodiment, the bearing unit 3 includes a first bearing frame 31, which provides a suitable limiting space for the material frame. The frame structure forms a circumferential constraint on the material frame, enhancing its stability and preventing displacement or tilting during lifting or transport. Simultaneously, the frame structure reduces material usage and weight while maintaining load-bearing strength. Combined with the smooth operation of the scissor arm assembly 22 and the linear drive component 21, this further improves the safety and efficiency of material transport, better meeting the stable material bearing requirements in metal powder injection molding production. Furthermore, the weight reduction is achieved through the hollow frame structure, reducing material usage and thus the weight of the bearing unit 3 and the entire trolley. This makes the trolley movement lighter and more flexible, improving transport efficiency. It also reduces the load-bearing pressure on the base 1 and lifting unit 2, extending the equipment's service life. Additionally, it reduces the power consumption of the linear drive component 21 during lifting, further adapting to the efficient and stable operation requirements in metal powder injection molding production and enhancing the overall process's economy and smoothness. Optionally, as... Figures 1-2 As shown, in this embodiment, the first supporting frame 31 is a rectangular frame. In other embodiments, the first supporting frame 31 can also be an elliptical or circular frame.

[0050] Preferably, such as Figures 1-3As shown, in this embodiment, the carrying unit 3 also includes a first quick-release component 32, which is installed on the side of the first carrying frame 31. A hook extends from the bottom of the material frame, and the hook is at the output end of the first quick-release component 32 to limit the material frame, forming a mechanical locking structure. This structure can firmly restrain the material frame within the first carrying frame 31, preventing the material frame from accidentally detaching due to vibration or collision when the trolley moves, lifts, or stops. This significantly improves the stability and reliability of the material frame positioning. At the same time, this hook and the first quick-release component 32 cooperation structure facilitates the quick locking and unlocking of the material frame without affecting the material handling efficiency. This further adapts to the requirements of material transfer safety and ease of operation in metal powder injection molding production, ensuring the stability of the product in the connection between various processes.

[0051] Preferably, such as Figures 1-2 As shown, in this embodiment, the supporting unit 3 further includes a buffer 33, which is installed on the frame where the first quick-release piece 32 is located. The buffer 33 absorbs impact force when the material frame comes into contact with the frame during placement or movement, reducing the collision force between the material frame and the frame of the first supporting frame 31, and the first quick-release piece 32. This prevents damage to the material frame or internal products due to hard contact, and reduces the impact of vibrations from collisions on the overall stability of the trolley. Combined with the limiting function of the quick-release piece, it ensures the material frame is firmly positioned and improves the safety and stability of the material frame placement through buffer protection. This further adapts to the strict requirements for material protection in metal powder injection molding production, reducing the risk of product damage due to collisions and enhancing operational reliability. Optionally, in this embodiment, the buffer 33 is made of rubber. In other embodiments, the buffer 33 can also be made of materials such as silicone or latex.

[0052] Preferably, such as Figures 1-2 As shown, in this embodiment, the supporting unit 3 also includes a limiting track 34. The limiting track 34 is arranged on two side frames perpendicular to the side frame where the first quick-release piece 32 is located. The limiting track 34 extends along the extension direction of the side frame where it is located. The wheels of the material frame are set on the limiting track 34, which can provide a directional guidance path for the movement of the material frame within the first supporting frame 31, limit the movement direction of the material frame, ensure that the material frame is accurately pushed in or pulled out along the track, and avoid deviation and jamming. At the same time, together with the first quick-release piece 32 and the buffer piece 33, a complete constraint system is formed from movement guidance to positioning and locking to collision buffering, making the picking and placing of the material frame smoother and the positioning more accurate, significantly reducing the difficulty of operation, reducing the frictional wear between the material frame and the first supporting frame 31, and further adapting to the requirements of high efficiency and stability of material transfer in metal powder injection molding production, improving the overall smoothness and safety of the operation.

[0053] Optionally, in this embodiment, the limiting track 34 consists of two spaced-apart elongated metal strips. These elongated metal strips extend along the extension direction of their respective frames. The material frame is positioned between the two spaced-apart elongated metal strips, providing a lateral rigid constraint and a precise movement guide channel for the material frame. The space between the two metal strips creates a stable limit on both sides of the material frame, preventing lateral displacement during pushing, pulling, or transfer. The rigidity of the metal material ensures the load-bearing capacity and wear resistance of the limiting track 34, extending its service life. Simultaneously, the elongated strips reduce the contact area with the material frame, lowering frictional resistance and making the material frame move more smoothly. This further improves the accuracy of the material frame positioning and the stability of the transfer, meeting the requirements for efficient and safe material transfer in metal powder injection molding production, and enhancing the overall reliability and durability of the operation.

[0054] Preferably, such as Figures 1-2 As shown, in this embodiment, the base 1 includes a base body 11 and a limiting member 12. The limiting member 12 is disposed on the edge of the base body 11, which can form a more accurate positioning and stable constraint on the material frame placed in the base body 11, further restricting the displacement of the material frame in the frame, avoiding the material frame from shifting or colliding due to vibration or shaking during the movement of the trolley or lifting, significantly reducing the risk of the material frame and the internal material falling or being damaged, while improving the accuracy of the material frame placement, ensuring accurate positioning during docking or transfer with other equipment, better adapting to the strict requirements for stable material transfer and precise operation in metal powder injection molding production, and enhancing the reliability and safety of the overall operation.

[0055] Preferably, such as Figures 1-2 As shown, in this embodiment, the limiting member 12 is an N-shaped handle. The N-shaped handle extends along the extension direction of its surrounding frame, providing a convenient gripping structure for operators to handle the material frame while simultaneously limiting its position. The extended shape of the N-shaped handle enhances lateral limiting of the material frame, preventing it from shifting during transport or lifting. It also allows operators to easily move the material frame without needing to find additional leverage points, improving the efficiency of picking up and placing the material frame. This balances limiting and operational convenience, further adapting to the high-efficiency and stable operational requirements of metal powder injection molding production, and enhancing the practicality and safety of the overall process. In other embodiments, the limiting member 12 can also be a positioning pin structure or an L-shaped baffle structure, etc.

[0056] Preferably, such as Figures 1-2As shown, in this embodiment, the base 1 also includes a pusher 13, which is installed on the edge of the base body 11. This provides the operator with a more convenient point of leverage, making it easier to move the entire trolley. The advantage is that the operator can easily control the direction and speed of the trolley through the pusher 13, which is especially easy to operate when precise docking with equipment or adjusting the position of the trolley is required. At the same time, the pusher 13 is combined with the base body 11 without taking up too much extra space, and can work with the universal wheels 41 of the moving unit 4 to improve the flexibility of the trolley's turning and movement, reduce manpower consumption, improve transfer efficiency, and further adapt to the efficient and convenient operation requirements in metal powder injection molding production, enhancing the practicality and smoothness of the overall operation.

[0057] Optionally, such as Figures 1-2 As shown, in this embodiment, the moving unit 4 includes four casters 41, which are spaced apart below the base 1. The four casters 41 are located at the four vertices of the base 1, providing stable support and flexible steering for the trolley. The arrangement at the four vertices ensures even force distribution on the base 1, preventing the trolley from tilting due to a shift in the center of gravity and improving overall stability. The flexible steering of the casters 41 allows the trolley to easily adjust its direction even in narrow production workshops, facilitating precise docking with equipment or movement between production stations. The spaced arrangement also ensures smooth movement, reducing material swaying caused by bumps, further adapting to the requirements of flexible and stable transfer in metal powder injection molding production, enhancing operational efficiency and material safety. In other embodiments, three, five, or six casters 41 may be provided. In other embodiments, the casters 41 may also be replaced by tracked wheels or pneumatic wheels.

[0058] Preferably, such as Figures 1-2 As shown, in this embodiment, the moving unit 4 also includes at least one brake component 42, which is mounted on the caster wheel 41. When the trolley is stopped, locking the caster wheel 41 prevents it from rolling randomly, thus achieving stable positioning of the trolley. This avoids displacement of the trolley due to external force or slight unevenness of the ground when loading or unloading material frames, adjusting height, or performing other operations on docking equipment (such as a vacuum sintering furnace). It ensures precise alignment of the material frame with the equipment inlet, reduces the risk of product collisions and drops during operation, and provides a safe and stable working environment for operators. It also improves the accuracy and reliability of process connections and better adapts to the strict requirements for operational precision and safety in metal powder injection molding production.

[0059] Optionally, such as Figures 1-2 As shown, in this embodiment, two brake components 42 are provided, and the two brake components 42 are provided on two universal wheels 41 on the same side. In other embodiments, the brake components 42 may also be provided on two non-adjacent universal wheels 41.

[0060] This embodiment also provides a product transfer device for metal powder injection molding. In this embodiment, the product transfer device for metal powder injection molding includes a material frame, a processing plate, and a trolley. The material frame is placed on the trolley, and the product is placed on the processing plate. The processing plate is installed inside the material frame. The trolley in the product transfer device for metal powder injection molding can realize the stable and precise transfer of the product from the catalytic degreasing process to the sintering process in the production process. The processing plate provides a suitable placement carrier for the product, the material frame protects and constrains the processing plate and the product, and the trolley realizes the overall transfer by means of lifting and moving functions. The cooperation of the three can ensure that the product is not affected by collision and shaking during the transfer process, reduce the risk of damage, and improve the efficiency and convenience of product transfer. It accurately adapts to the connection requirements between various processes in metal powder injection molding production, and enhances the continuity, stability and safety of the overall production process.

[0061] Optionally, such as Figures 1-2 As shown, in this embodiment, the processing plate is a graphite plate, which can adapt to the product transfer requirements after catalytic degreasing in metal powder injection molding. Especially in the process of transferring from the catalytic degreasing equipment to the vacuum sintering furnace, the graphite plate is resistant to high temperature and has strong chemical stability. It can directly carry the product into the vacuum sintering furnace for sintering without changing the carrier plate during the transfer process, reducing intermediate steps in product transfer and avoiding product damage caused by plate replacement. At the same time, the characteristics of the graphite plate are compatible with the vacuum sintering process, which can ensure the quality stability of the product during the sintering process. With the precise height adjustment function of the trolley, the graphite plate and the product can be smoothly pushed into the vacuum sintering furnace, reducing the difficulty of operation, improving production efficiency, and reducing the risk of product damage caused by improper transfer.
