Description

Technical Field

[0001] This utility model belongs to the field of molding press technology, specifically a powder feeder diverter plate for a hydraulic powder molding machine. Background Technology

[0002] During operation, the powder feeder of the hydraulic powder molding machine is mainly responsible for conveying the powder evenly and stably to each cavity of the mold to ensure that each cavity is filled with the same amount of powder. The powder feeder sends the powder into the powder box through the pushing mechanism, and the distribution plate distributes the powder reasonably so that it flows evenly into each cavity.

[0003] However, in the current design of powder feeders, powder blockage and material jamming are prone to occur between the various distribution plates in the powder box. Since traditional distribution plates usually adopt a common rectangular partition plate structure, powder is easily adhered to the distribution plate due to accumulation, friction or static electricity during the flow process, which prevents the powder from passing through smoothly. When the powder fork picks up the material, if the powder blockage fails to fill the mold cavity smoothly, it may result in insufficient powder picking, causing the press to experience air pressure during the pressing process, leading to air pressure mold explosion. Utility Model Content

[0004] The purpose of this utility model is to provide a powder feeder diverter plate for a hydraulic powder molding machine, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A powder feeder diverter plate for a hydraulic powder forming machine is provided, including a powder box base. Several diverter plate assemblies are arranged on the upper part of the powder box base. Each diverter plate assembly includes a diverter plate base, which is disposed on the upper part of the powder box base. Several mounting slots are provided on the upper part of the diverter plate base, and guide blocks are provided on the upper part of the several mounting slots. Both sides of the guide blocks are provided with inclined surfaces.

[0006] Furthermore, the angle between the inclined plane and the horizontal plane is α, where α is 30° to 60°. In this embodiment, the angle α between the inclined plane and the horizontal plane on the guide block can be selected as 45°. Selecting the inclined plane angle as 45° can utilize gravity to make the powder slide down and reduce the stagnation of the powder on the surface, thereby improving fluidity. If the angle is too small, the powder may not flow smoothly, while if the angle is too large, the powder flow rate may be too fast and the distribution may be uneven. The inclined plane makes the powder evenly dispersed along both sides of the guide block, reducing the flow deviation caused by accumulation or electrostatic adsorption, and reducing the risk of material jamming.

[0007] Furthermore, the inclined surface is coated with a Teflon coating, which helps to drive the powder down the guide plate by gravity, and the low friction characteristics of the Teflon coating can further reduce powder retention and improve powder feeding efficiency.

[0008] Furthermore, the thickness of the Teflon coating is 25-50μm. The Teflon coating is suitable for powders with poor flowability, easy adhesion, or easy agglomeration, such as hydraulic powder, to ensure good anti-sticking effect, while also taking into account wear resistance and service life. If the coating is too thin (<25μm), it may not provide sufficient low friction effect, causing the powder to easily accumulate or flow unevenly. If the coating is too thick (>50μm), the coating surface may not be smooth enough, affecting the flowability of the powder and increasing production costs.

[0009] Furthermore, the distributor plate base has several threaded holes on both sides, and the distributor plate base is tightly connected to the side plate of the powder box by bolts to ensure that the distributor plate is firmly fixed inside the powder box.

[0010] Furthermore, the upper part of the flow divider base is provided with bolt holes, and the bolt connection method is adopted, so that the flow divider base can be easily disassembled and replaced to adapt to different types of powders or production process requirements.

[0011] Furthermore, the powder box base is provided with several mounting holes. In the powder feeding system of the hydraulic powder forming machine, the mounting holes on the powder box base correspond one-to-one with the bolt holes on the upper part of the distributor plate base. The bolt connection method is adopted, which makes the distributor plate base easy to disassemble and replace in order to adapt to different powder types or production processes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By installing several flow divider assemblies on the powder box base, and each flow divider assembly is equipped with several guide blocks with inclined surfaces on both sides, the powder can be more smoothly dispersed during the flow process, reducing powder accumulation and blockage caused by sharp or right-angled edges. Guided by the inclined surfaces of the guide blocks, the powder can be evenly distributed to every cavity of the mold, thereby ensuring that the amount of powder in each cavity is consistent, allowing the powder to flow smoothly, reducing accumulation points, improving powder feeding efficiency, reducing powder blockage and material jamming, avoiding air pressure mold explosion caused by uneven powder feeding, and improving production safety and equipment stability.

[0026] Please see Figure 1-4 As shown in the embodiment of this utility model, a powder feeder diversion plate for a hydraulic powder forming machine includes a powder box base 1. A plurality of diversion plate assemblies 2 are arranged on the upper part of the powder box base 1. The diversion plate assembly 2 includes a diversion plate base 21. The diversion plate base 21 is arranged on the upper part of the powder box base 1. A plurality of mounting grooves 22 are arranged on the upper part of the diversion plate base 21. A guide block 23 is arranged on the upper part of the plurality of mounting grooves 22. An inclined surface 24 is arranged on both sides of the guide block 23.

[0027] By installing several flow divider assemblies 2 on the powder box base 1, and each flow divider assembly 2 is equipped with several guide blocks 23, the guide blocks 23 are designed with inclined surfaces 24 on both sides, so that the powder can be more smoothly dispersed during the flow process, reducing powder accumulation and blockage caused by sharp or right-angled edges. Guided by the inclined surfaces 24 of the guide blocks 23, the powder can be evenly distributed to each cavity of the mold, thereby ensuring that the amount of powder in each cavity is consistent. By enabling the powder to flow smoothly through the flow divider assembly 2, the accumulation points are reduced, the powder feeding efficiency is improved, the powder blockage and material jamming are reduced, and the air pressure mold explosion caused by uneven powder feeding is avoided, thus improving production safety and equipment stability.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the angle between the inclined plane 24 and the horizontal plane is α, where α is 30° to 60°. In this embodiment, the angle α between the inclined plane 24 on the guide block 23 and the horizontal plane can be selected as 45°. An angle of 45° on the inclined plane 24 can utilize gravity to make the powder slide down, and can also reduce the stagnation of the powder on the surface and improve the flowability. If the angle is too small, the powder may not flow smoothly, while if the angle is too large, the powder flow rate may be too fast and the distribution may be uneven. The inclined plane 24 makes the powder evenly dispersed along both sides of the guide block 23, reducing the flow deviation caused by accumulation or electrostatic adsorption, and reducing the risk of material jamming.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the surface of the inclined plane 24 is coated with a Teflon coating. The inclined plane 24 is at a 45° angle, which helps to drive the powder down the guide plate by gravity. The low friction characteristics of the Teflon coating can further reduce powder retention and improve powder feeding efficiency.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the thickness of the Teflon coating is 25-50μm. Teflon coating is suitable for powders with poor flowability, easy adhesion or agglomeration, such as hydraulic powder, to ensure good anti-sticking effect, while taking into account wear resistance and service life. If the coating is too thin (<25μm), it may not provide a sufficient low friction effect, causing the powder to easily accumulate or flow unevenly. If the coating is too thick (>50μm), the coating surface may not be smooth enough, affecting the flowability of the powder and increasing production costs.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the distributor base 21 has several threaded holes 211 on both sides. The distributor base 21 is tightly connected to the side plate of the powder box by bolts to ensure that the distributor is firmly fixed inside the powder box.

[0032] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the upper part of the manifold base 21 is provided with bolt holes 212, and the bolt connection method is adopted, so that the manifold base 21 can be easily disassembled and replaced to adapt to different types of powders or production process requirements.

[0033] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the powder box base 1 is provided with several mounting holes 11. In the powder feeding system of the hydraulic powder forming machine, the mounting holes 11 on the powder box base 1 correspond one-to-one with the bolt holes 212 on the upper part of the distributor plate base 21. The bolt connection method is adopted so that the distributor plate base 21 can be easily disassembled and replaced to adapt to different powder types or production processes.

[0034] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
