Method for improving assembling strength of plastic outer cylinder and metal bearing assembly of washing equipment

Abstract

The invention belongs to the technical field of washing machines, and particularly provides a method for improving the assembling strength of a plastic outer cylinder and a metal bearing assembly of washing equipment. The method aims to solve the problems that the metal bearing assembly is likely to fall off from the plastic outer cylinder by adopting a mode of additionally installing a blocking rib, the machining technology is complicated, the method does not improve the bonding performance between the metal bearing assembly and the plastic outer cylinder, and in the using process, the metal bearing assembly can still be separated from the plastic outer cylinder. In order to achieve the purpose, the method for improving the assembling strength of the plastic outer cylinder and the metal bearing assembly of the washing equipment includes the steps that the metal bearing assembly is preheated to the set temperature; and the plastic outer cylinder and the metal bearing assembly are connected through injection molding. By means of the above process method, the bonding performance between the plastic outer cylinder and the metal bearing assembly can be improved, the strength of injection molding connection between the plastic outer cylinder and the metal bearing assembly is improved, and therefore the metal bearing assembly is prevented from being disengaged from the plastic outer cylinder.

Description

Technical field [0001] The present invention belongs to the technical field of washing machines, particularly to provide a method and a plastic outer cylinder metal fitting strength of the bearing assembly for lifting the washing apparatus. Background technique [0002] In the prior art, high speed rotation of the inner tube to protect the washing machine, an outer generally cylindrical plastic flame-resistant, high-strength, but the bearing assembly typically made of metal. Both during the injection molding, because of different materials, for the most demanding process requirements. In actual use, the problem of metal coming out of the bearing assembly from the plastic outer cylinder prone. [0003] Plastic and metal outer cylinder assembly method of assembling the bearing strength of a conventional apparatus commonly used to enhance the washing installation stop rib way to improve the problem of metal release easily from the bearing assembly outer plastic cylinder. [0004] Ho...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the metal bearing assembly is easy to come out of the plastic outer cylinder by adding ribs, the processing technology is complicated, and this method does not improve the metal bearing assembly. Due to the combination between the outer cylinders, during use, the problem that the metal bearing assembly will come out of the plastic outer cylinder still occurs. The present invention provides a method for improving the assembly strength of the plastic outer cylinder and the metal bearing assembly of the washing machine, including Preheating the metal bearing assembly to a set temperature; connecting the plastic outer cylinder with the metal bearing assembly by injection molding
