Abstract

The invention discloses a die for a brake base of an electrically-propelled wheelchair. The die comprises a movable die plate, a fixed die plate capable of cooperating with the movable die plate, a movable die seat fixedly arranged at and connected with the bottom of the movable die plate and an ejection mechanism arranged between the movable die plate and the movable die seat, capable of going up and down between the movable die plate and the movable die seat and used for demolding; and the die further comprises a nozzle used for injecting liquid wax. According to the invention, based on the structural characteristics of the brake base needing wax injection of the electrically-propelled wheelchair, a movable die and a fixed die which are mutually cooperated and can form a cavity with a same shape as the part of the brake base needing wax injection of the electrically-propelled wheelchair are designed; and the die provided by the invention has a simple structure, is convenient to operate and enables a high-precision wax mould for the brake base of the electrically-propelled wheelchair to be obtained.

Description

technical field [0001] The invention relates to a mold for a brake base of an electric wheelchair. Background technique [0002] The electric wheelchair brake base is an important part of the electric wheelchair. Its shape is relatively complex, and the processing accuracy is very high. The traditional machining method is used to produce parts. The process is complicated and the production efficiency is low. It needs to obtain the parts blank by casting. , and then get the parts through finishing. Before casting, it is necessary to obtain the casting model of the part through wax injection, and it is necessary to design a special wax injection mold to realize it. Contents of the invention [0003] The object of the present invention is to provide a mold for the brake base of an electric wheelchair with high production efficiency. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: electric wheelchair brake base mould,...
