A kind of production equipment and technology of balance ring of washing machine

Abstract

The invention discloses a production device and technology for a washing machine balance ring. The production device comprises a two-plate type injection molding machine, upper and lower ring injection molding sealing dies and an automatic rotation platform. The two-plate type injection molding machine is a double-screw injection molding machine. The automatic rotation platform is provided with die plates for installing the dies. The automatic rotation platform is fixed to the two-plate type injection molding machine. The automatic rotation platform is located between an injection molding machine movable die plate and an injection molding machine fixed die plate and can rotate and move forwards and backwards. The upper and lower ring injection molding sealing dies are divided into the upper ring injection molding sealing dies and the lower ring injection molding sealing dies. The technology comprises the first step of primary die assembly and primary injection molding, the second step of die opening rotation, the third step of secondary die assembly, the fourth step of secondary injection molding sealing, the fifth step of automatic workpiece taking and the sixth step of checking and warehousing. According to the production device and technology, the automation degree is high, the production quality is stable, the first pass yield is high, and energy consumption and cost are low.

Description

technical field [0001] The invention relates to the field of production of a balance ring of a washing machine, in particular to production equipment and a process for a balance ring of a washing machine. Background technique [0002] The balance ring of the washing machine is usually composed of a lower balance ring and an upper balance ring. The upper balance ring is fastened and fixedly connected to the lower balance ring. The upper balance ring and the lower balance ring form a cavity for accommodating the balance liquid. The balance ring is installed on the top of the dehydration bucket of the washing machine, and contains a certain volume of balance liquid in the balance ring, which starts the balance when rotating. When the dehydration bucket starts or stops, the inertia of the balance liquid is used to counteract or buffer the inertia of the dehydration bucket. [0003] In my country, at present, the balance rings used in the fully automatic pulsator washing machine...
