Technical Field

[0001] The invention relates to a carrier tray stacking and placing device for metal powder injection molding and a use method thereof. Background Art

[0002] Metal powder injection molding is a new component processing technology formed by introducing plastic injection molding technology into the field of powder metallurgy. Its production consists of the steps of mixing granulation, injection molding, degreasing sintering and post-processing.

[0003] The degreasing and sintering step is an important link that determines the cost and quality. During sintering, the temperature needs to be precisely controlled close to the critical melting point of the metal. In this way, physical and chemical changes occur at high temperatures, causing the gaps between the metal particles to become infinitely smaller and dense, thereby obtaining metal parts with a density of more than 98% of that of the plate material, thereby making its various mechanical properties reach more than 98% of that of the plate material. When the semi-finished product is heated to a molten state, it is also the most fragile time and can easily be deformed by external force.

[0004] In order to better sinter the semi-finished products, the cooled semi-finished products are usually placed on a carrier plate. After they are placed, a certain sintering space is left by stacking the plates. Repeating the above operation can assist the sintering of the semi-finished products. However, many of the existing factories place large quantities of semi-finished products on plates, and many of them can only be completed after a large number of manpower assists the operation of the machine. The efficiency is low and a large amount of manpower costs are consumed. Therefore, a carrier plate stacking plate stacking placement device for metal powder injection molding is urgently needed to solve the above problems. Summary of the invention
