Die for high-strength ratchet shaft machining, and machining process thereof

Abstract

The invention discloses a die for high-strength ratchet shaft machining, and a machining process thereof, and belongs to the technical field of machining. According to the die for high-strength ratchet shaft machining, and the machining process thereof, a pressure-driven exhaust plate can be pushed through an electric telescopic rod to move downwards to extrude and exhaust air in an upper die baseand a lower die base, so that the influence of the air on machining is reduced, and a negative-pressure state is formed; a casting material is injected through a storage bin, the casting material uniformly and slowly flows out through discharge spray heads, and meanwhile, the casting material passes through a filter plate; buoyancy balls float on the surface of the casting material, a connectionplate presses discharge holes to exhaust, and in the period, impurities and filter residue in the casting material are filtered through an impurity filter plate; an elastic pull rope pulls an arc-shaped stretching film to shrink, meanwhile, the filter plate is driven to move upwards, and then a lower butting magnetic block is butted with an upper butting magnetic block, and machining injection iscompleted, so that the influence of the air and the impurities on the machining quality is reduced, the strength of a ratchet shaft is increased, and the performance of the ratchet shaft is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and more specifically relates to a mold for processing a high-strength ratchet shaft and a processing technology thereof. Background technique [0002] A ratchet is defined as a gear with a rigid toothed surface or friction surface on the outer or inner edge, and is an important component of the ratchet mechanism. Pushed by the pawl to make a stepping motion, the characteristic of this meshing motion is that the ratchet can only rotate in one direction, but not reversed. [0003] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. A mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the artic...

AI Technical Summary

Problems solved by technology

The mold generally includes two parts: the movable mold and the fixed mold (or punch and concave mold). The two parts can be separated or combined. When they are separated, the parts are taken out. It is difficult to avoid the existence of air, which may affect the quality of mold processing products and form empty grooves. At the same time, during mold processing, there are refractory impurities in the injection material, which affects the quality of processed products
