Description

Technical Field

[0001] The invention relates to the technical field of metal powder processing, in particular to metal powder injection molding equipment. Background Art

[0002] Metal powder refers to a group of metal particles with a size of less than 1mm. It includes single metal powder, alloy powder and some refractory compound powders with metallic properties, and is the main raw material for powder metallurgy. Metal powder injection molding technology is to evenly mix solid powder with organic binder, inject it into the mold cavity by injection molding machine for solidification, and then remove the binder in the molded blank by chemical or thermal decomposition method, and finally obtain the final product through sintering and densification.

[0003] In the existing metal powder injection molding equipment technology, the mixing method of the components is mostly mechanical stirring. To ensure sufficient mixing, a long time of stirring and mixing is required, resulting in low efficiency. At the same time, there is a risk that even if the mixing time is sufficient, it may not be fully mixed due to the wide stirring range. In addition, when the metal powder is fed into the metal injection molding machine for injection molding, the loading and unloading of the material body requires manual operation, which is not convenient for quick operation and affects the injection molding efficiency.

[0004] For example, a metal powder injection molding device disclosed in China's invention patent publication number CN115846662A comprises a mixing rack, which is assembled between a mixing tank and a feeding pipe assembly, and a plurality of throwing-off assemblies are arranged on the mixing rack; the mixing rack is also provided with a plurality of rotating feeding rod structures distributed in a ring array, the rotating feeding rod structure comprises a threaded rod, the threaded rod is threadedly matched with a pushing plate structure, and the pushing plate structure is used to move the powder into the inside of the throwing-off assembly and drive the threaded rod to rotate; the threaded rod and the rotating feeding rod structure also comprise a rotating shaft which is integrally fixedly connected, and the rotating shaft drives the spiral plate distributed along its axis to rotate after the threaded rod rotates, and the spiral plate squeezes the powder inside the spiral plate to push it onto a plurality of throwing-off holes opened on the side wall of the throwing-off pipe, and widely disperses it into the inside of the mixing tank, so as to expand the contact area and quickly and fully mix it with the adhesive in the air.

[0005] Although the above device solves the problem of mixing and stirring the metal powder before injection molding, the injection molding after mixing and stirring is not easy to operate, the mixed metal powder is not easy to discharge for injection molding, and there may be residual metal powder.

[0006] Therefore, we propose a metal powder injection molding equipment to solve the above problems. Summary of the invention

[0019] The present invention has holes passing through the injection molding seat, the lower cavity plate and the bottom surface of the rubber plug, and a limiting column is installed through the hole, so that the descending path of the injection molding seat remains stable when the telescopic column drives it to descend, and when the lower cavity plate contacts the upper surface of the connecting seat, the outer surface of the rubber plug contacts the sealing column, and the connection between the lower cavity plate and the connecting seat is sealed. At the same time, when the lower cavity plate continues to move downward, the telescopic rod is squeezed to squeeze the compression spring, so that the compression spring and the telescopic rod move in opposite directions, and the connection between the lower cavity plate and the connecting seat is tighter, thereby improving the injection molding effect of the metal powder.
