Powder molding machine and molding method for molding multilayer products using the molding machine

Abstract

The invention relates to a powder molding machine for molding a multi-layer powder product and a molding method thereof. The molding method comprises the following steps: 1) determining the filling depth of each section of powder in accordance with the requirements of the product, and adjusting the position of each filling adjustment spacing screw rod through a first filling adjustment mechanism, a second filling adjustment mechanism,..., and an n filling adjustment mechanism; determining the position of each demolding swing arm in accordance with the position of each filling adjustment spacing screw rod, namely that the position of a first demolding swing arm is corresponding to the position of a first filling adjustment spacing screw rod,..., and the position of an (n-1) demolding swing arm is corresponding to the position of an (n-1) filling adjustment spacing screw rod; and locking each demolding swing arm; 2) driving a mold cavity mechanism to move upwards under the action of a resetting cylinder, and stopping the upward movement when the first filling adjustment spacing screw rod is reached, thus completing the first filling; 3) releasing the first demolding swing arm, driving the mold cavity mechanism to continue moving upwards under the action of the resetting cylinder, and stopping the upward movement when the second filling adjustment spacing screw rod is reached, thus completing the second filling; 4) repeating the step 3) until the n filling is completed; and 5) after the filling is completed, moving an upper punch downwards to press and mold the product, and demolding to obtain the final product. The invention provides a powder molding machine capable of well molding a multi-layer powder product and a molding method thereof.

Description

technical field [0001] The invention relates to a powder molding machine and a molding method thereof, in particular to a powder molding machine for molding multilayer powder products and a molding method thereof. Background technique [0002] With the emergence of mechanical powder molding machines, the production of complex, small, high-volume, high-strength products has become a reality, bringing great opportunities to the powder metallurgy industry and creating favorable conditions for the development of the powder metallurgy industry. [0003] Nowadays, more stringent requirements are put forward for the quality and complexity of powder metallurgy products. For example, if a product requires oil-containing double-layer powder or multi-layer powder during the pressing process, it needs to be fed twice or multiple times. , double filling or multiple filling; the current production method of this kind of product is generally produced by semi-manual mechanical productio...

[0003] Nowadays, more stringent requirements are put forward for the quality and complexity of powder metallurgy products. For example, if a product requires oil-containing double-layer powder or multi-layer powder during the pressing process, it needs to be fed twice or multiple times. , double filling or multiple filling; the current production method of this kind of product is generally produced by semi-manual mechanical production, but this production method has low production efficiency, and it is also difficult to produce due to the semi-manual and semi-mechanical production.
