[0035] Reference Figure 1-Figure 8, an ammoniated aluminum ceramic injection molding device, including an equipment base 1, a first mold 2 is arranged on the top of the equipment base 1, a movable second mold 21 is arranged on the top of the equipment base 1 on one side of the first mold 2, a conveying cylinder 3 is connected to one side of the first mold 2, and a feeding hopper 31 is connected to the top of the conveying cylinder 3, an isolation sleeve 4 is arranged in the inner wall of the conveying cylinder 3, and one end of the isolation sleeve 4 is fixedly connected to the inner wall of the conveying cylinder 3; a rotating shaft 6 is arranged in the conveying cylinder 3, and a cavity 62 is opened inside the rotating shaft 6; a connecting cylinder 52 is arranged above the rotating shaft 6, when the rotating shaft 6 rotates, the heat generated by the inner wall of the conveying cylinder 3 is extracted through the connecting cylinder 52 and then transported to the cavity 62, so as to heat the outer wall of the rotating shaft 6, and at the same time, the excess air when the material is transported in the conveying cylinder 3 can be extracted.

[0036] In the conventional molding method, when processing aluminum amide ceramics, the molding operation is generally performed by injection molding. In the existing molding equipment, the material particles can be heated while being transported, but the existing heating method has a relatively simple layout, resulting in uneven heating of the aluminum amide ceramics during transportation, a short heating contact time, and ultimately resulting in blockage of the injection port, or poor molding quality of the material entering the mold cavity, which seriously affects the output quality of the equipment. For this reason, in the present invention, a heating zone is provided on the inner wall of the conveying cylinder 3, so that the material transported inside the conveying cylinder 3 can be heated, and the auger blades 61 provided on the rotating shaft 6 can be used to slowly transport the material and better heat the material evenly, so that the material is always in a moving state, reducing material adhesion, and can The conveyed materials are conveyed in batches to avoid the occurrence of concentrated accumulation of materials and improve the heating efficiency of the materials. Through the setting of the isolation sleeve 4 and the connecting tube 52, on the one hand, the hot air generated in the heating zone of the conveying tube 3 can be extracted and utilized, and then conveyed to the inside of the cavity 62 to heat the conveying and stirring position on the rotating shaft 6, thereby further improving the heating effect on the material, improving the heating efficiency, and avoiding the occurrence of incomplete heating of the material. On the other hand, an air protection layer can be formed outside the heating zone of the conveying tube 3 to avoid excessive heat dissipation and improve the utilization rate of thermal energy. Through the setting of the connecting tube 52, the air mixed with the material conveying at the conveying tube 3 can be extracted to reduce the generation of bubbles in the melting process of the material, thereby further improving the quality of material injection molding.

[0037] In a preferred embodiment, referring to Figure 6 and Figure 7A heating chamber 41 is provided on the inner wall of the conveying cylinder 3, an air inlet pipe 43 is provided on the outer wall of the conveying cylinder 3, a heating plate 42 is installed inside the heating chamber 41, an air intake pipe 51 is embedded in the outer wall of the conveying cylinder 3, an air inlet of the air intake pipe 51 contacts the other end of the isolation sleeve 4, one end of the air intake pipe 51 passes through the equipment base 1 and is fixedly connected with a connecting cylinder 52, a one-way valve is provided at the connection between the connecting cylinder 52 and the air intake pipe 51, a side surface of the connecting cylinder 52 is connected with an air delivery pipe 58, a one-way valve is provided at the connection between the air delivery pipe 58 and the connecting cylinder 52, a fixing rod 59 is sleeved on the surface of the air delivery pipe 58, one end of the fixing rod 59 is fixedly connected to the connecting cylinder 52;

[0038] Among them, the setting of the isolation sleeve 4 can divide the interior of the heating chamber 41 into two chambers. In the chamber where the heating plate 42 is set, the air in the chamber can be heated by the heating of the heating plate 42. The hot air in the cavity is extracted through the suction pipe 51, and then transported to the inside of the connecting tube 52, and then transported out through the air pipe 58, and finally enters the cavity 62 in the rotating shaft 6. The hot air inside the cavity 62 can heat the entire surface of the rotating shaft 6. Since the outer wall surface of the rotating shaft 6 is in direct contact with the conveyed material, the conveyed material can be heated from the inside during the conveying and heating process, thereby improving the overall heating effect of the material and making the material heating more uniform.

[0039] It should be noted that, although one end of the isolation sleeve 4 is fixedly connected to the inner wall of the conveying tube 3, the fixed connection portion divides the air inlet at the air inlet pipe 43 into two halves, and the other end of the isolation sleeve 4 is also divided into two halves at the air inlet position of the suction pipe 51, so that the air entering the air inlet pipe 43, on the one hand, passes through the outer chamber in the heating chamber 41 to form an air flow protection layer to avoid the transfer and dissipation of heat and improve the utilization rate of heat. On the other hand, through the design of this structure, it can prevent the operator's hand from accidentally touching the outer wall of the conveying tube 3 and causing scalding injuries, and play a certain protective role. The air entering the air inlet pipe 43 passes through the inner chamber in the heating chamber 41, so that the air in the chamber circulates, extending the service life of the heating plate 42;

[0040] The interior of the auger blade 61 can be set as a hollow structure, which is connected with the cavity 62. With such a structure, when the material conveying and stirring components come into contact with the material, the heating effect is better, and the adhesion of the material is reduced to a certain extent.

[0041] In a preferred embodiment, referring to Figure 5 and Figure 6The connecting cylinder 52 is fixedly mounted on the outer wall of the equipment base 1, and a piston 53 is slidably connected inside the connecting cylinder 52. A moving rod 54 is fixedly connected to the bottom of the piston 53. A tension spring 57 is fixed between one end of the moving rod 54, the piston 53 and the connecting cylinder 52. The tension spring 57 is sleeved on the surface of the moving rod 54. One end of the moving rod 54 is fixedly connected to a limiting block 55. A cam 56 is attached to the bottom of the limiting block 55. A rotating part is arranged at the axis of the cam 56. The rotating part includes a rotating shaft 6 fixed at the axis of the cam 56. A driving part 60 is installed on the outer wall surface of the rotating shaft 6. The driving part 60 is fixed on the outer wall of one side of the equipment base 1. One end of the rotating shaft 6 extends to the inside of the conveying cylinder 3. The outer wall of the rotating shaft 6 is located inside the conveying cylinder 3 and a screw blade 61 is fixed. The equipment base 1 A sealing plate 64 is fixedly installed inside, and the sealing plate 64 is rotatably connected to the rotating shaft 6 through a bearing. One end of the air supply pipe 58 is installed together with one end of the rotating shaft 6 through a rotating joint. The surface of the rotating shaft 6 is located on one side of the auger blade 61 and is provided with an air outlet valve 63. An extraction pipe 73 is fixed to the other end of the connecting tube 52. A fixing plate 71 is installed on the equipment base 1. An exhaust port 72 is opened on the surface of the fixing plate 71. The extraction pipe 73 runs through the exhaust port 72 and the sealing plate 64. An exhaust pipe 74 is provided on the outer wall of one side of the other end of the connecting tube 52. One side surface of the second mold 21 is fixedly connected to the output end of the hydraulic rod. The hydraulic rod is installed on the equipment base 1. A one-way valve is provided at the connection between the extraction pipe 73 and the connecting tube 52, and a one-way valve is provided at the connection between the exhaust pipe 74 and the connecting tube 52.

[0042] The above scheme is adopted, wherein the driving part 60 adopts a reduction motor instead of a drive. When the driving part 60 is started, the rotating shaft 6 is driven to rotate. The rotating shaft 6 is equipped with a cam 56, which reciprocates and squeezes the limit block 55, and finally makes the piston 53 reciprocate up and down on the inner wall of the connecting cylinder 52. When the piston 53 moves down, the hot air generated in the heating zone inside the conveying cylinder 3 is extracted through the suction pipe 51. As the piston 53 moves up, the hot air is squeezed and transported to the inside of the cavity 62 through the air delivery pipe 58. When the internal air pressure of the cavity 62 exceeds a certain pressure value, the air inside the cavity 62 is emptied. The gas is ejected through the air outlet valve 63, and the ejected air is discharged to the outside of the equipment through the exhaust port 72, which will not cause equipment operation failure. The setting of the tension spring 57 allows the piston 53 to elastically rebound and reset, so that the component continues to operate. When the piston 53 reciprocates up and down, the air inside the conveying cylinder 3 can be extracted through the extraction pipe 73, so that the material mixed in the conveyed material can be extracted and then discharged to the outside through the exhaust pipe 74, so as to avoid the material heating more air during the heating process to generate bubbles, thereby affecting the subsequent material injection molding effect.

[0043] When the material is injection molded, the second mold 21 is driven to move toward the first mold 2 by starting the hydraulic rod, and the two are fitted and assembled together to form a complete mold cavity, which is convenient for disassembly and assembly.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
