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.
