Powder product finishing machine mold base core rod regulating device and finishing process thereof

Abstract

The invention relates to a powder product finishing machine mold base core rod regulating device and a finishing process thereof. The powder product finishing machine mold base core rod regulating device is characterized in that a mold stripping regulating bar fixedly connected to an upper punching fixed plate is arranged on the upper punching fixed plate and passes through a female mold plate and a lower punching fixed plate which are sequentially arranged at the lower end of the upper punching fixed plate; a lower fixed seat is arranged at the lower part of the lower punching fixed plate; cavities into which a core rod penetrates are formed in the female mold plate, the lower punching fixed plate and the lower fixed seat; the lower end of the core rod passes through a core rod air cylinder arranged in the lower fixed seat and is connected to a core rod piston; the lower surface of the core rod piston leans against a regulating threaded rod which can move up and down; and a regulating block which can move up and down along the mold stripping regulating bar is arranged at a place of the mold stripping regulating bar, which is located at the lower part of the lower punching fixed plate. The powder product finishing machine mold base core rod regulating device has the beneficial effects that the operating stroke of the core rod can be adjusted; and when a product is stripped from a mold, the core rod is stripped from a female mold along with the product, then the product expands after an exogenic action does not exist, and the binding force of the core rod is reduced; and the core rod is stripped from the inner hole of the product under the action of the core rod air cylinder force, thus, the core rod is less likely to be damaged and the service life of the core rod is prolonged.

Description

technical field [0001] The invention relates to an important mechanism on a powder product finishing machine, that is, a powder product finishing machine formwork mandrel adjusting device used for finishing the powder product after sintering. Background technique [0002] According to the production process of powder products, powder products need to be sintered and finished before they can be used. The stroke of the mandrel used on the mold frame of the existing powder product finishing machine is fixed and cannot be adjusted. The mandrel is removed together with the product at one time. Mold, because the female mold, lower punch, and the product have been tightly held outside the mandrel after the product is finished, and the mandrel has to overcome a large binding force to get rid of the product when demoulding, so the mandrel is easy to wear and tear. ,damage. Contents of the invention [0003] In view of the above defects, the present invention aims to provide a fo...
