Problems solved by technology

[0003] However, the washing machine will inevitably make noise during the working process. When the washing machine is running, due to the collision between the inner drum of the washing machine and the shell of the machine body, there will be a bang sound. Various abnormal vibrations and noises will appear due to aging of parts, deformation of springs, etc.

Abstract

The invention provides a manufacturing method of a weight balancing block for lowering noise and absorbing shock of a washing machine, and relates to the field of weight balancing blocks. The method comprises the following steps of 1, mixing, by weight, 12 parts of slag, 8 parts of cement, 3 parts of carborundum, 2 parts of gravel and 0.5 part of foaming agent, and adding 4 parts of water to sufficiently stir the materials to form a sizing agent; 2, putting the sizing agent into a microwave heater, wherein the treatment time is 5-10 min, the treated sizing agent is poured to a mold, and a weight balancing core is obtained after cooling and curing are conducted; 3, fixedly connecting the lower portion of the weight balancing core with a shockproof damping block to obtain the weight balancing block. According to the manufacturing method of the weight balancing block for lowering the noise and absorbing the shock of the washing machine, the weight balancing block can solve the problem of weight balancing, and the noise and vibration generated when the washing machine works are also lowered.

Description

technical field [0001] The invention relates to the field of counterweights, in particular to a method for manufacturing a counterweight for a washing machine with noise reduction and shock absorption. Background technique [0002] The inside of the washing machine is equipped with counterweights, so that the washing machine has a certain weight, which is used to reduce the vibration and shaking of the washing machine in the working process and ensure its stability and balance. [0003] However, the washing machine will inevitably make noise during the working process. When the washing machine is running, due to the collision between the inner drum of the washing machine and the shell of the machine body, there will be a bang sound. Various abnormal vibrations and noises will appear due to aging of parts, spring deformation and other reasons. [0004] Noise can cause physical and psychological harm to people: damage to hearing, harmful to the cardiovascular system, affect t...
