Description

Technical Field

[0001] This utility model relates to the field of high-speed steel spray forming technology, specifically to a high-speed steel spray forming mold device. Background Technology

[0002] High-speed steel spray forming mold is a key tooling equipment specifically used for near-net-shape forming processes of high-speed steel materials. Spray forming technology atomizes molten high-speed steel into fine droplets under the protection of inert gas, and guides them through high-speed airflow to directly spray and deposit them onto a mold cavity or substrate of a specific shape, which then quickly solidifies to form a blank that is close to the shape of the final part. The mold must have good thermal stability, wear resistance and thermal conductivity to withstand the impact of high-temperature molten metal and repeated thermal cycles to prevent deformation or cracking. On conventional production lines, molds are usually fixed by manually tightening the side clamps one by one with a wrench. This method of adjustment is time-consuming, cannot accurately control the clamping force, and is greatly affected by the operator's experience. It often results in one side being too tight while the other side is loose. At the same time, if a vibration device is present, it is usually an external independent device. The vibration energy is greatly lost during transmission and cannot effectively act on the mold cavity area, resulting in insufficient venting of the molten metal and unstable molding quality.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example 1

[0020] Reference Figure 1-4The first embodiment of this utility model provides a support mechanism 1 including a control panel 101, a mold 102, a vibration motor 103, and a placement plate 104. The mold 102 is disposed on one side of the control panel 101, the vibration motor 103 is disposed at the lower end of the mold 102, and the surface of the placement plate 104 is fixedly connected to the surface of the vibration motor 103. A fixing mechanism 2 is disposed at the lower end of the mold 102, and a cooperating mechanism 4 is disposed on the fixing mechanism 2. The fixing mechanism 2 is used to clamp and fix molds 102 of different sizes, and the cooperating mechanism 4 is used to assist in the fixing process.

[0021] Specifically, this utility model solves the problems of low clamping efficiency, poor clamping stability, and uneven molding quality of mold 102 in existing high-speed steel production. By setting an adjustable fixing mechanism 2 and a matching mechanism 4, it can quickly adapt to and firmly clamp molds 102 of different sizes, improving clamping accuracy and efficiency. Combined with the integrated design of vibration motor 103 and placement plate 104, it can effectively transmit vibration after pouring, promote the air venting and compaction of molten metal, reduce internal defects, and the overall structure realizes rapid positioning and fixing of mold 102 and high-quality molding, improving production stability and product consistency.

[0022] Furthermore, in the production process of high-speed steel, the precise installation and stable fixing of the mold 102 is a key link to ensure the smooth progress of subsequent processes. First, the operator needs to select a suitable mold 102 according to the specifications of the high-speed steel to be produced and place it stably on the placement platform 201 of the equipment. After the mold 102 is firmly fixed, the formal production stage of high-speed steel can begin. Molten metal is injected into the cavity of the positioned mold 102 to start the forming process. In order to improve the density and uniformity of the casting, after the pouring is completed, the vibration motor 103 integrated on the placement plate 104 can be started. When the vibration motor 103 is working, it generates high-frequency micro-amplitude vibration, which is transmitted to the mold 102 as a whole through the placement platform 201. This causes the molten metal in the mold 102 to fully vent air during the solidification process, reduce defects such as porosity and shrinkage, thereby improving the internal quality and performance consistency of the high-speed steel material. Example 2

[0023] The second embodiment of this utility model provides a fixing mechanism 2 including a placement platform 201, a support frame 202, a servo motor 203, a double-ended screw 204, a transmission plate 205, a clamping block 206, a bearing seat 207, and a support base 208. The right side surface of the placement platform 201 is slidably connected to the lower end of the support frame 202 via a sliding groove. The inner wall of the support frame 202 is fixedly connected to the surface of the servo motor 203. The output end of the servo motor 203 is fixedly connected to the right end of the double-ended screw 204. The surface of the double-ended screw 204 is threadedly connected to the inner wall of the transmission plate 205. The surface of the transmission plate 205 is fixedly connected to the surface of the clamping block 206. The middle surface of the double-ended screw 204 is connected to the bearing seat. The inner wall of 207 is rotatably connected, and the two ends of the double-headed screw 204 are rotatably connected to the inner walls of the two bearing seats 208 respectively. An auxiliary mechanism 3 is provided on the fixing mechanism 2. The auxiliary mechanism 3 includes a guide rod 301 and a stroke sleeve 302. The surface of the guide rod 301 is slidably connected to the inner wall of the stroke sleeve 302. The lower surface of the mold 102 is in contact with the upper surface of the placement platform 201. The surface of the clamping block 206 is in contact with the surface of the mold 102. The lower ends of the bearing seat 207 and the bearing seat 208 are slidably connected to the upper end of the placement platform 201 through a sliding groove. The two ends of the guide rod 301 are fixedly connected to the outer surface of the bearing seat 208. The surface of the stroke sleeve 302 is fixedly connected to the outer surface of the transmission plate 205.

[0024] Specifically, the fixing mechanism 2 improves the accuracy and stability of clamping the mold 102 by driving the double-headed screw 204 with opposite threads at both ends, enabling the transmission block to move synchronously towards the center or both sides. This achieves clamping of molds 102 of different sizes, which not only solves the problems of uneven clamping and low efficiency in traditional clamping methods, but also significantly reduces the possibility of off-center loading and jamming during clamping. In addition, the cooperation between the guide rod 301 and the stroke sleeve 302 further enhances the stability of the transmission block movement, ensuring the smooth progress of the entire clamping process and improving production safety and yield.

[0025] Furthermore, after completing the initial positioning, the precision adjustment stage of the clamping block 206 begins. The servo motor 203 equipped on the fixing mechanism 2 is activated, and its output shaft is connected to a double-ended screw 204. The two ends of the screw are machined with threads in opposite directions and are respectively equipped with transmission blocks that mesh with them. When the servo motor 203 drives the double-ended screw 204 to rotate, since the threads at both ends are in opposite directions, the two transmission blocks will move synchronously towards the middle, thereby driving the clamping block 206 to symmetrically approach the side wall of the mold 102 in the horizontal direction. As the double-ended screw 204 continues to rotate, the clamping block 206 gradually adheres to and presses against the surface of the mold 102, achieving a uniform and reliable clamping force. During this process, the stroke sleeve 302 set at the rear end of the transmission block slides along the guide rod 301 fixed on the bearing seat 208, effectively improving the stability of the transmission block's movement, preventing uneven loading or jamming, and ensuring a smooth and precise clamping process. Example 3

[0026] The third embodiment of this utility model provides a mating mechanism 4 including a mounting box 401, a fixing plate 402, an electric push rod 403, and a connecting plate 404. The inner wall of the mounting box 401 is fixedly connected to the surface of the fixing plate 402. The inner wall of the fixing plate 402 is fixedly connected to the middle surface of the electric push rod 403. The output end of the electric push rod 403 is fixedly connected to the inner wall of the connecting plate 404. The upper end of the mounting box 401 is fixedly connected to the lower end of the placement platform 201. The upper end of the connecting plate 404 is fixedly connected to the inner wall of the bearing seat 207. The lower end of the mounting box 401 is slidably connected to the surface of the placement plate 104.

[0027] Specifically, the cooperating mechanism 4 addresses the issues of low initial positioning efficiency and difficulty in manual adjustment during the clamping process of mold 102. By setting up a linkage structure between the electric push rod 403 and the connecting plate 404, the output end of the electric push rod 403 drives the connecting plate 404 to move the bearing seat 207 along the slide groove, thereby realizing the synchronous opposite or opposite movement of the two fixing mechanisms 2 on the placement table 201. This allows for rapid adjustment of the initial spacing of the clamping blocks 206, adapting to the upper mold and positioning requirements of molds 102 of different widths, improving the automation level and response speed of the clamping operation. Combined with the stable connection structure between the mounting box 401 and the fixing plate 402, it ensures stable and reliable transmission process, avoids off-center load, and provides an accurate pre-positioning basis for the subsequent precision clamping driven by the servo motor 203, thus improving the overall operating efficiency and operational safety of the equipment.

[0028] Furthermore, the electric push rod 403 installed at the lower end of the placement platform 201 is activated via the control panel 101. The electric push rod 403 drives the bearing seats 207 on both sides to move along the slide groove direction through the connecting plate 404, causing the fixing mechanisms 2 at both ends of the placement platform 201 to slide laterally in opposite directions on the surface of the placement platform 201. This sliding process causes the clamping block 206 to initially approach the side wall of the mold 102, achieving initial positioning and contact with the mold 102, laying the foundation for subsequent precise clamping.

[0029] Working principle:

[0030] In the production process of high-speed steel, the precise installation and stable fixation of the mold 102 is a key step to ensure the smooth progress of subsequent processes. First, the operator needs to select a suitable mold 102 according to the specifications of the high-speed steel to be produced and place it stably on the placement platform 201 of the equipment. To ensure that the mold 102 does not shift during processing, the position of the clamping block 206 must be adjusted according to the actual size of the mold 102. At this time, the electric push rod 403 installed at the lower end of the placement platform 201 is activated through the control panel 101. The electric push rod 403 synchronously drives both sides through the connecting plate 404. The bearing seat 207 moves along the slide groove, causing the fixing mechanisms 2 at both ends of the placement platform 201 to slide laterally in opposite directions on the surface of the placement platform 201. This sliding process causes the clamping block 206 to initially approach the side wall of the mold 102, achieving initial positioning and contact with the mold 102, laying the foundation for subsequent precise clamping. After the initial positioning is completed, the precision adjustment stage of the clamping block 206 begins. The servo motor 203 equipped on the fixing mechanism 2 is started, and its output shaft is connected to a double-ended screw 204. The two ends of the screw are machined with threads in opposite directions and are respectively equipped with transmissions that mesh with it. When the servo motor 203 drives the double-ended screw 204 to rotate, the two transmission blocks will move synchronously towards the middle due to the opposite direction of the threads at both ends. This causes the clamping block 206 to symmetrically approach the side wall of the mold 102 in the horizontal direction. As the double-ended screw 204 continues to rotate, the clamping block 206 gradually adheres to and presses against the surface of the mold 102, achieving a uniform and reliable clamping force. During this process, the stroke sleeve 302 set at the rear end of the transmission block slides along the guide rod 301 fixed on the bearing seat 208, effectively improving the stability of the transmission block's movement, preventing uneven loading or jamming, and ensuring a smooth clamping process. With precision, once the mold 102 is firmly fixed, the high-speed steel production stage can begin. Molten metal is injected into the positioned cavity of the mold 102 to start the forming process. To improve the density and uniformity of the casting, after pouring, the vibration motor 103 integrated on the placement plate 104 can be activated. When the vibration motor 103 is working, it generates high-frequency micro-amplitude vibration, which is transmitted to the entire mold 102 through the placement table 201. This promotes the molten metal in the mold 102 to fully vent air during solidification, reduce defects such as porosity and shrinkage, thereby improving the internal quality and performance consistency of the high-speed steel material.

[0031] In summary, the coordinated operation of the electric push rod, the servo motor-driven double-headed screw transmission mechanism, and the vibration motor achieves precise positioning of the mold on the placement table, reliable clamping, and uniform molding during the casting process. The electric push rod completes the coarse adjustment and positioning of the clamping mechanism, while the servo motor and the double-headed screw system enable synchronous and precise feeding of the clamping blocks, ensuring uniform distribution of clamping force. The subsequent introduction of the vibration motor effectively improves the density and uniformity of the microstructure during the solidification process of high-speed steel. Together, these three elements ensure the stability of the mold and the consistency of the final product quality during the high-speed steel production process.
