Abstract

The invention discloses a gear billet mold, which comprises a bottom mold base, a bottom mold, and a gear mold. The gear mold is provided with more than two tooth grooves, and a gear mold is installed on the bottom mold. The bottom mold base and the bottom mold The mold is integrated, and a side groove and a push rod are arranged between the bottom mold base and the bottom mold. The gap fit is adopted between the side groove and the push rod, and the side groove communicates with the cooling groove in the tooth groove. The rod and the side groove are co-fitted inside the bottom mold, and the side groove and the pressure chamber are in the same plane. The driving force generated by the push rod is pushed horizontally until it touches the connecting bump, and the air pressure inside the pressure chamber will be continuously squeezed, and the pressure chamber will be matched. The continuously squeezed pressure pushes upward the piston enclosed in the tooth groove cavity. The tooth groove closed by the piston and the steel plate mainly provides the shaping effect for the sawtooth of the gear, and when the piston pushes up, it is fixed in the tooth groove The inner sawtooth is brought out, and the pulling force is changed into a pushing force to realize that the sawtooth will not break on the mold when it is brought up.

Description

technical field [0001] The invention relates to the technical field of gear manufacturing, in particular to a gear billet mold. Background technique [0002] Molds, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products, in short, molds are tools 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 article through the change of the physical state of the formed material, and the gear blank mold is the mold used to produce gears. [0003] Due to the small size of the teeth of the small gear, this type of gear is easy to be lifted when the mold is released because the teeth are thin and thin, and it may even break on the mold. When cleaning the broken teeth on the mold Also more time-consuming. Contents of the invention...
