Description

Novel mould pressing die for powder processing Technical Field The utility model relates to the technical field of mould pressing moulds, in particular to a novel mould pressing mould for powder processing. Background The molding die is a core tool for compression molding of a material in a powder metallurgy process, and fills a cavity with a powder, a pellet, or a molten material by applying pressure and forms a predetermined shape. In the prior art, two side pressure plates are connected through a pin shaft, but in the demolding process, the two side pressure plates can be separated only by knocking through a hammer head, vibration is generated during knocking, a formed product is easy to damage, and the side pressure plates are knocked down. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a novel mould pressing mould for powder processing. The aim of the utility model is realized by the following technical scheme: The utility model provides a novel mould pressing die is used in powder processing, includes base, locating plate, side board, tip baffle and holding down plate, be the symmetry on the base and be provided with the side board, the locating plate is fixed to be set up on the base and both sides respectively with the side board cooperation, be the symmetry on the both ends inboard of side board and be provided with the inclined plane, two be provided with spacing arch between the inclined plane, spacing bellied both ends respectively with the both ends parallel and level of locating plate, two be provided with between the inclined plane the tip baffle, the tip of locating plate with spacing bellied tip all with the tip baffle cooperation, the both sides side of holding down plate with spacing protruding cooperation, the both ends terminal surface of holding down plate with the tip baffle cooperation, two link to each other through locking assembly between the both ends of side board respectively.
