Description

Technical Field

[0001] The present application relates to the field of washing machine mold structures, and in particular to a core-pulling structure mold for a washing machine rear cover. Background Art

[0002] A washing machine is a cleaning appliance that uses electricity to generate mechanical action to wash clothes. With the improvement of living standards, washing machines have become an indispensable appliance in modern households. The structure of a washing machine includes a front cover, a body, and a rear cover. When setting the mold structure for the rear cover of a washing machine, it is often necessary to perform core extraction to ensure that the molded object can be smoothly released from the mold.

[0003] When a common washing machine rear cover mold is performing core pulling, the mold opening and closing operations are realized by the oil cylinder, so that the molded object can be smoothly separated from the mold. During the core pulling operation, the stopper is fixed on the inclined top and located in the undercut. When the core is pulled, the inclined top is driven to make the stopper located in the undercut separate from the undercut. The contact surface between the stopper and the undercut is squeezed and rubbed. Long-term friction can easily damage the stopper. Utility Model Content
