[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a hydraulic powder molding machine, including a molding machine body 1. A molding mold 2 is provided on the bottom inner wall of the molding machine body 1. The molding machine body 1 is the prior art, including hydraulic cylinders, punch heads, etc. The principle of which can be learned by those skilled in the art through technical manuals, and will not be described in detail here. The bottom inner wall of the molding machine body 1 is provided with a scraper 4 for scraping the powder on the top of the molding mold 2. The scraper 4 has a concave structure, and the shortest distance of the concavity is not less than the diameter of the mold cavity at the top of the molding mold 2. A dust collection head 12 for collecting powder is provided on one side of the molding machine body 1. The bottom inner wall of the dust collection head 12 is flush with the top of the molding mold 2. An external pipe 13 connected to an external vacuum cleaner is fixed to the rear side of the dust collection head 12 by a clamp. When scraping the powder off the top of the molding die 2, the scraper 4 moves smoothly along the top surface of the molding die 2. Its concave structure can effectively gather the powder and guide it to the position of the suction head 12. The suction head 12 is connected to an external vacuum cleaner through the external pipe 13. When the vacuum cleaner is started, a negative pressure is generated at the suction head 12, which quickly sucks in the powder scraped off by the scraper 4 and transports it to the dust collection bag in the external vacuum cleaner through the external pipe 13. This not only avoids the loss caused by the powder falling from the mold onto the molding machine, but also allows the scraped powder to be recycled and reused in time, greatly reducing powder waste and improving production efficiency and material utilization.

[0024] In this utility model, the bottom inner wall of the molding machine body 1 is fixed with two guide rails 3 located on both sides of the molding mold 2 by bolts. A movable seat 5 is slidably connected on the guide rail 3. A sliding rod 15 is welded to the top of the movable seat 5. The two ends of the scraper 4 are slidably connected to the two sliding rods 15 respectively. A rubber pad 14 is glued to the top of the two movable seats 5. The rubber pad 14 buffers the fall of the scraper 4 and protects the scraper 4. As the scraper 4 moves along the top surface of the forming mold 2, the scraper 4 will drive the moving seat 5 to slide in a straight line on the guide rail 3, thereby ensuring that the scraper 4 will not deviate during the movement. Meanwhile, the sliding connection design between the slide bar 15 and the scraper 4 allows the scraper 4 to be finely adjusted up and down within a certain range according to the height of the molding mold 2, so as to better fit the top surface of the molding mold 2 and improve the powder removal effect. When it is necessary to perform powder scraping operation on molding dies 2 of different specifications, it is only necessary to adjust the position of scraper 4 on slide bar 15 and replace the molding die 2 with a suitable one. The operation is convenient and quick, and there is no need to carry out large-scale modification of the entire equipment, which greatly improves the versatility and applicability of the equipment. The guide rail 3 and the moving seat 5 are both made of high-strength and wear-resistant materials, which can withstand the friction and impact generated by the scraper 4 during movement, ensuring the stability and reliability of the equipment during long-term use. In addition, the main body 1 of the molding machine can also be equipped with a drive mechanism for driving the moving seat 5 to slide on the guide rail 3. The drive mechanism can be a common linear drive device such as a cylinder or a linear motor. The drive mechanism drives the scraper 4 to move, reducing labor costs.

[0025] Furthermore, one end of the guide rail 3 is fixed with a touch switch 6 by bolts. The trigger point of the touch switch 6 faces the scraper 4, and the touch switch 6 is electrically connected to the external vacuum cleaner. When the scraper 4 moves along the guide rail 3 to the moving seat 5 and contacts the touch switch 6, the touch switch 6 will be triggered. At this time, the touch switch 6 will send a start signal to the external vacuum cleaner, so that the vacuum cleaner starts working. This design realizes the automatic start of the vacuum cleaner after the scraper 4 moves into place, without the need for manual operation to turn on the vacuum cleaner, which further improves the automation and efficiency of production. Among them, the touch switch 6 is made of high-quality materials, which has good durability and stability, and can be accurately triggered during long-term use, reducing production interruptions caused by switch failure.

[0026] Furthermore, a baffle 7 is welded to the other end of the guide rail 3, and the top of the baffle 7 is a slope 8; The baffle 7 can effectively prevent the movable seat 5 from detaching from the end of the guide rail 3 when it slides on the guide rail 3, thus playing a safety limiting role. The design of the inclined surface 8 can guide the scraper 4 to slide smoothly during the falling process.

[0027] Furthermore, one side of each of the two slide rods 15 is rotatably connected to an arc-shaped elastic plate 16 via a hinge. One end of the arc-shaped elastic plate 16 is connected to the scraper 4. The arc-shaped elastic plate 16 and the scraper 4 are connected by a plug-in connection. The top of the scraper 4 is provided with a socket 9. The bottom end of the arc-shaped elastic plate 16 is integrally formed with a plug 17, which can be inserted into the socket 9. The arc-shaped elastic plate 16 provides a downward pressure to the scraper 4, allowing the scraper 4 to adhere more closely to the top surface of the molding mold 2 during movement, further enhancing the powder removal effect. Meanwhile, the elastic design of the arc-shaped elastic plate 16 can be elastically deformed to a certain extent according to the usage requirements of the scraper 4 on the forming mold 2 of different heights or different specifications, so as to adapt to different working scenarios. The plug-in connection method makes the assembly and disassembly of the arc-shaped elastic plate 16 and the scraper 4 simple and quick, and makes the height adjustment of the scraper 4 easy. In practical use, simply raise the scraper 4 and move it so that it is positioned on the molding mold 2. At this time, bend the arc-shaped elastic plate 16 so that the insert 17 is inserted into the socket 9. This completes the quick assembly of the scraper 4 and the arc-shaped elastic plate 16. Then, release the scraper 4. Under the downward elastic force of the arc-shaped elastic plate 16, the scraper 4 will fit tightly against the top surface of the molding mold 2, preparing for subsequent powder scraping operations. When disassembly is required, simply bend the arc-shaped elastic plate 16 again to pull the insert 17 out of the socket 9, and the arc-shaped elastic plate 16 can be easily separated from the scraper 4. The whole process does not require the use of additional tools, and the operation is simple and efficient. This design not only improves the flexibility and ease of use of the equipment, but also reduces maintenance costs and time. In addition, the arc-shaped elastic plate 16 can be made of materials with different elastic coefficients according to the actual use, so as to meet the elastic buffering requirements under different specifications of molding mold 2 and different powder scraping requirements. Those skilled in the art can set it according to actual needs.

[0028] Furthermore, two guide frames 10 are fixed to one side of the molding machine body 1 by bolts. The guide frames 10 are slidably connected to the dust collection head 12. An electric push rod 11 is fixed to the bottom outer wall of the molding machine body 1 by bolts. The movable end of the electric push rod 11 is fixed to the dust collection head 12. The extension and retraction of the electric push rod 11 can drive the suction head 12 to slide up and down along the guide frame 10. This allows the position of the suction head 12 to be flexibly adjusted according to the height of the molding die 2 and the actual powder scraping operation requirements, ensuring that the suction head 12 is always in the optimal powder recovery position, thereby further improving the efficiency and effectiveness of powder recovery. When performing powder scraping operations on molding dies of different specifications 2, the vacuum head 12 can be quickly adjusted to a suitable height simply by controlling the extension and retraction length of the electric push rod 11. There is no need to perform tedious disassembly and reinstallation of the vacuum head 12, which greatly saves time and labor costs. Meanwhile, the guide frame 10 ensures the stability and straightness of the vacuum head 12 during the up-and-down sliding process, preventing the vacuum head 12 from shifting or shaking during movement, thus ensuring the accuracy and reliability of powder recovery. The electric push rod 11 is made of high-quality motor and transmission components, which has precise control performance and stable power output, and can operate stably for a long time, providing a reliable guarantee for the position adjustment of the vacuum head 12.

[0029] The working principle of this utility model: When it is necessary to scrape off the powder on the top of the molding die 2, raise the scraper 4 and move the scraper 4 so that the scraper 4 is positioned on the molding die 2. The curved elastic plate 16 is bent so that the insert 17 is inserted into the socket 9. Then the scraper 4 is released. Under the downward elastic force of the curved elastic plate 16, the scraper 4 will fit tightly against the top surface of the molding mold 2. The scraper 4 moves smoothly along the top surface of the molding die 2, and its concave structure can effectively gather the powder and guide it to the position of the dust collection head 12. When the scraper 4 moves along the guide rail 3 to the moving seat 5 and contacts the touch switch 6, the touch switch 6 will be triggered. At this time, the touch switch 6 will send a start signal to the external vacuum cleaner, so that the vacuum cleaner starts to work. After the vacuum cleaner is started, a negative pressure is generated at the suction head 12, which quickly sucks in the powder scraped off by the scraper 4 and transports it through the external pipe 13 to the dust collection bag inside the external vacuum cleaner. This not only avoids the loss caused by the powder falling from the mold onto the molding machine, but also allows the scraped powder to be recycled and reused in a timely manner, greatly reducing powder waste and improving production efficiency and material utilization.
