Brake wheel full metal casting mold

Abstract

The invention provides a brake wheel all metal casting die and relates to a die. The brake wheel all metal casting die comprises an outer metal die, an inner metal die and an inner hole metal die, wherein the outer metal die is used for forming the outer surface of the outer wall of the brake wheel; the inner metal die is used for forming the wall of the inner cavity of the brake wheel; the innerhole metal die is used for forming an inner hole of the brake wheel; the outer metal die comprises an outer metal die I for forming the side face and the upper end face of the outer wall of the brakewheel and an outer metal die II for forming the lower end face of the outer wall; the inner metal die comprises an inner metal die I for forming the outside cavity wall of the inner cavity of the brake wheel and an inner metal die II for forming the inside cavity wall of the inner cavity of the brake wheel and connected with the inner metal die I; the outer wall of the inner metal die II is connected with a control piece capable of pulling the inner metal die II to demold; and through holes for accommodating the inner hole metal die are formed in the middle parts of the outer metal die I and the inner metal die II respectively. The casting die also comprises a pull rod, a pressing sleeve and a piston rod, wherein the pull rod is arranged in the through holes of the inner hole metal die; the pressing sleeve is fixedly connected with the top of the pull rod; and the piston rod is connected with the bottom end of the pull rod and is used for pushing and pulling the pull rod and the pressing sleeve so as to demold the inner hole metal die conveniently.

Description

technical field [0001] The invention relates to a mold, in particular to a casting mold. Background technique [0002] The permanent magnet synchronous gearless traction machine is the latest traction machine of the elevator, and it is also the power equipment of the elevator. Its function is to transport and transmit power to make the elevator move. The permanent magnet synchronous gearless traction machine is composed of a rotor equipped with permanent magnets, a stator equipped with coils, a brake, a traction wheel, and a machine base. The inner wall of the rotor is equipped with permanent magnets, which generate the magnetic field required by the motor, and the outer wall of the rotor is combined with the brake to act as a brake. Therefore, the rotor is also called a brake wheel. The brake wheel is a very important part of the permanent magnet motor. Due to the direct output torque, high strength is required, and the friction between the outer circle and the brake plays...

Problems solved by technology

[0003] Existing castings usually use sand molds or lost foam for molding. Whether it is sand mold or lost foam, a pair of molds can only be cast once and then scrapped; due to many molding processes, the requirements for operators are high, and the quality of the product The production cycle is long, time-consuming and labor-intensive, and the production efficiency is low; it needs a large space to store production materials such as molding sand, molds and molds; from the perspective of environmental protection: the use of sand mold casting will generate a lot of dust pollution to the environment; Toluene, ethylbenzene and other gases produced during the pyrolysis of styrene will also pollute the environment
