Description

Technical Field

[0001] This utility model relates to the field of powder extrusion molding technology, specifically a high-speed extrusion die. Background Technology

[0002] Carbon nanotube-reinforced metal matrix composites are a novel type of high-performance composite material. Carbon nanotubes possess excellent mechanical properties, exhibiting extremely high strength and modulus, with a tensile strength reaching 200 GPa, 100 times that of carbon steel. The composite material is prepared by uniformly mixing metal powder and carbon nanotube powder, followed by processes such as pressing and sintering. The high strength, hardness, and toughness of this composite material make it ideal for mold making. The basic principle of powder metallurgy is to mix various metal powders, shape them under certain pressure, and then sinter them at a temperature below the metal's melting point, forming a metallurgical bond between the powder particles. This process requires high-pressure molding; therefore, carbon nanotube-reinforced metal matrix composites are suitable for use in powder metallurgy extrusion molding dies.

[0003] Chinese patent CN214111621U discloses an extrusion structure for a powder forming machine to prevent powder spillage. The structure includes a lower pressure body, an upper pressure body, a gas guiding and overflow prevention mechanism, a triangular iron, and a base. The upper pressure body is positioned above the lower pressure body, and the base is fixed to the lower end face of the lower pressure body. The triangular iron is welded to the left and right sides of the lower pressure body. The gas guiding and overflow prevention mechanism is located inside the lower and upper pressure bodies and includes a pressure block, an extrusion head, a limiting rod, a gas guiding groove, a first cylinder, a movable sealing rod, a tray, and a second cylinder. The pressure block is fixed to the upper end face of the upper pressure body. The limiting rod is assembled on the lower end face of the upper pressure body. The first cylinder is fixed inside the upper pressure body. The movable sealing rod is connected to the lower end face of the cylinder. The extrusion head is fixed on the lower end face of the upper pressure body. The air guide groove is opened inside the upper pressure body and the extrusion head. The second cylinder is fixed inside the lower side of the lower pressure body. The tray is connected to the upper side of the second cylinder. The extrusion head has a movable groove inside, and the inner diameter of the movable groove is the same as the diameter of the movable sealing rod. Through the structural cooperation of the pressure block, extrusion head, limiting rod, air guide groove, first cylinder, movable sealing rod, tray and second cylinder, the powder is prevented from being sprayed out with the gas during the powder extrusion process.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent uses a structure consisting of a pressure block, an extrusion head, a limiting rod, an air guide groove, a cylinder one, a movable sealing rod, a tray, and a cylinder two to prevent powder from being sprayed out with gas during the powder extrusion process. However, it cannot eject the molded workpiece from the upper and lower mold positions at the same time as the upper and lower molds separate, and it cannot perform intermittent alternating feeding, resulting in low production efficiency.

This is conducive to the continuous intermittent alternating feeding of the forming devices on the left and right sides.

[0018] 2. The downward movement of the sliding plate drives the first fixed base, rotating hook, and limiting bracket of the feeding device to move downward. The rotating hook moves downward and contacts the second fixed rod, hooking the second fixed rod. At this time, after the metal powder is formed, the sliding plate moves upward, driving the upper mold to move upward. The upward movement of the sliding plate also drives the first fixed base, rotating hook, and limiting bracket to move upward. At the same time, the feeding device feeds the material. The sliding frame and buffer box of the feeding device move towards the lower mold. While feeding the material, the formed workpiece that is being lifted is pushed to the feeding plate. This facilitates the ejection of the workpiece from the lower mold position as the upper mold leaves the lower mold, thus improving production efficiency. Attached Figure Description

The extension rod 35 is fixedly installed on the upper side of the irregular bracket 34, and the two guide wheels 36 are rotatably connected to the left and right sides of the extension rod 35 through a rotating shaft.

[0037] The linear module 31 of the feeding device 3 moves to the left, causing the irregular bracket 34 to move to the left. The irregular bracket 34 moves to the left, causing the extension rod 35 and the guide wheel 36 to move to the left.

[0038] The feeding device 3 further includes a filling assembly. Two filling assemblies are respectively installed on the left and right sides of the irregular bracket 34. The filling assembly includes a sliding frame 37, a buffer box 38, and a discharge pipe 39. The sliding frame 37 is slidably connected to the slot on the upper side of the limiting plate 5. The buffer box 38 is fixedly installed on the upper side of the sliding frame 37. One end of the discharge pipe 39 is fixedly connected to the upper side of the buffer box 38, and the other end of the discharge pipe 39 is fixedly connected to the output end of the external quantitative conveyor.

[0039] The output end of the linear module 31 of the feeding device 3 moves to the left, causing the irregular support 34 to move to the left. The irregular support 34 moves to the left, causing the sliding frame 37, buffer box 38 and discharge pipe 39 to move to the left. The external quantitative conveyor conveys metal powder through the discharge pipe 39 and into the sliding frame 37 through the buffer box 38. The sliding frame 37 moves to the left to the position of the lower mold 212, and the metal powder falls into the lower mold 212.

The irregular support 34 moves to the right, causing the sliding frame 37 to move to the right. The sliding frame 37 moves to the right and scrapes away the excess metal powder. At this time, the lower mold 212 on the left side is finished feeding. The output end of the linear module 31 continues to move to the right to feed the lower mold 212 on the right side, which is beneficial for continuous intermittent alternating feeding of the forming devices 2 on the left and right sides.

[0040] Example 2: In some embodiments, such as Figures 1-7 In a preferred embodiment of this utility model, the feeding device 4 is symmetrically installed on the lower side of the sliding plate 24 along the central axis of the sliding plate 24. The feeding device 4 includes: a first fixed base 41, a rotating hook 42, and a limiting bracket 43. The first fixed base 41 is fixedly installed on the lower side of the sliding plate 24. The rotating hook 42 is rotatably connected to the end of the first fixed base 41 away from the sliding plate 24 through a rotating shaft. The hook-shaped end of the rotating hook 42 faces the central axis of the frame 1. The limiting bracket 43 is fixedly installed on the end of the first fixed base 41 close to the hook-shaped end of the rotating hook 42. An inclined surface 44 is provided on the lower side of the hook-shaped part of the rotating hook 42.

[0041] The feeding device 4 further includes a connecting assembly. Two connecting assemblies are symmetrically installed on the front and rear sides of the support plate 29 along the central axis of the support plate 29. The connecting assembly includes a second fixed base 45 and a second fixed rod 46. The second fixed base 45 is fixedly installed on the upper side of the support plate 29, and the second fixed rod 46 is fixedly installed on the upper side of the second fixed base 45. The second fixed rod 46 is located directly below the inclined surface 44. The limiting bracket 43 is used to limit the tilt angle of the rotating hook 42 in its natural state, so that the inclined surface 44 is located directly above the second fixed rod 46.

[0042] The sliding plate 24 moves downward, causing the first fixed base 41, rotating hook 42, and limiting bracket 43 of the feeding device 4 to move downward. The rotating hook 42 moves downward and contacts the second fixed rod 46. The inclined surface 44 on the lower side of the hook shape of the rotating hook 42 contacts the second fixed rod 46, causing the rotating hook 42 to rotate as it moves downward. After the inclined surface 44 of the rotating hook 42 passes the second fixed rod 46, the rotating hook 42 stops rotating and continues to move downward. The tilt angle of the upper side of the rotating hook 42 in its natural state makes the inclined surface 44 directly above the second fixed rod 46. After the hook shape of the rotating hook 42 has completely passed the second fixed rod 46, the rotating hook 42 returns to its initial state. At this time, the metal powder... After molding, the sliding plate 24 moves upward, causing the upper mold 26 to move upward. The upward movement of the sliding plate 24 causes the first fixed base 41, the rotating hook 42, and the limiting bracket 43 to move upward. The upward movement of the rotating hook 42 causes the rotating hook 42 to hook the second fixed rod 46. The upward movement of the second fixed rod 46 causes the second fixed base 45 to move upward. The upward movement of the second fixed base 45 causes the support plate 29 to move upward. The upward movement of the support plate 29 causes the ejector rod 211 to move upward. The upward movement of the ejector rod 211 lifts the molded workpiece from the lower mold 212. This facilitates the ejection of the workpiece from the lower mold 212 position at the same time as the upper mold 26 leaves the lower mold 212, thus improving production efficiency.

[0043] At the same time, the feeding device 3 feeds the material. The sliding frame 37 and the buffer box 38 of the feeding device 3 move towards the lower mold 212. While feeding the material, the formed workpiece that has been lifted is pushed to the unloading plate 6, which is conducive to unloading the material at the same time as feeding.

[0044] The feeding device 3 feeds the material. The extension rod 35 and guide wheel 36 of the feeding device 3 move toward the lower mold 212. The guide wheel 36 moves toward the lower mold 212 and contacts the hook-shaped side of the rotating hook 42, causing the rotating hook 42 to rotate away from the second fixed rod 46, causing the support plate 29 to fall. The gas spring 214 assists in supporting the support plate 29, causing it to fall slowly. The falling of the support plate 29 causes the top rod 211 to fall and return to its initial state.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
