Problems solved by technology

Although with the development of technology, multi-station injection molding machines have emerged, which can form multiple materials or multi-color injection molding at one time, but it is still impossible to perform those processes that require secondary processing, especially those that require welding of different parts.
This requires more equipment or labor for secondary processing and assembly, which consumes manpower, material resources and workshop space, and increases investment costs.

Embodiment Construction

[0030] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0031] Such as figure 1 As shown, it is a process flow chart for preparing the balance ring of the washing machine. The preparation method of the balance ring of the washing machine is obtained by automatic production of the intelligent production equipment of the balance ring of the washing machine, and specifically includes the following steps:

[0032] (1) Install the mold with the upper ring cavity and the lower ring cavity of the balance ring of the washing machine in the mold area of ​​the injection molding machine. After the mold is closed, the injection molding machine performs one injection molding to obtain the upper ring and the lower ring of the balance ring of the washing machine respectively. cooling molding;

[0033] (2) The injection molding machine opens the mold at one time, and the middle rotary mold rotates 180 at a time 0 , facing...

Abstract

The invention discloses a manufacturing method for a balancing ring of a washing machine, and the balancing ring is automatically produced by intelligent production equipment for the balancing ring of the washing machine. The manufacturing method specifically comprises the following steps of: (1) injection-molding in a mould region of an injection molding machine to form an upper ring and a lower ring of the balancing ring of the washing machine, and cooling and molding; (2) opening the injection molding machine to rotate a middle rotary mould of the mould by 180 degrees, and enabling a mould side with an upper ring to be opposite to a mould side with a lower ring; (3) introducing a hot melting device into the mould region of the injection molding machine, heating the upper ring and the lower ring to a needed hot melting temperature, and dropping the hot melting device out of the mould region; (4) closing the mould again for effectively melting the upper ring and the lower ring together, thereby forming the balancing ring of the washing machine; and (5) opening the mould to take out the balancing ring of the washing machine. According to the manufacturing method disclosed by the invention, injection-molding and melting of the upper ring and the lower ring of the balancing ring are carried out in the mould, and the balancing ring finished product has been the finished product while leaving a mould cavity, so that assembly quality stability and fit tightness of the balancing ring of the washing machine are improved, and therefore, manpower and material resources are saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliance processing, and more specifically, relates to an injection molding processing method for a balance ring of a washing machine, which improves the production efficiency and quality of the balance ring of a washing machine and reduces the occurrence of defective products. Background technique [0002] The balance ring of the washing machine is composed of the upper ring and the lower ring that need to be welded, and often requires multiple or single injection molding machines and multiple sets of molds for single production, and then the washing machine balance ring is placed in the two cavity molds manually or by a robot for heating , welding, testing. Although with the development of technology, multi-station injection molding machines have appeared, which can form multiple materials or multi-color injection molding at one time, but it is still impossible to perform those processes that...
