Abstract

The invention relates to a pre-foaming machine for lost foam casting and a working method thereof. The pre-foaming machine comprises a machine shell, a feeding assembly, a heating assembly, a conveying pipeline and a crushing assembly. The pre-foaming machine is reasonable in structural arrangement, the overall size is reduced, and integrated work of material heating, foaming and discharging is achieved; and through reasonable pipeline arrangement, foamed materials can be crushed very easily and conveyed to the exterior of the device through the pipeline, labor force is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a pre-foaming device, in particular to an integrated pre-foaming machine for lost foam casting capable of realizing fast foaming and fast discharge and its working method. Background technique [0002] The application field of lost foam mold is getting wider and wider, and it is a new casting technology with great development prospects. The lost foam mold has many advantages, such as: (1) The lost foam mold casting has precise size and shape, good reproducibility, has the characteristics of precision casting, and the surface finish of the casting is high. (2) The sand core and core-making department have been cancelled, and casting defects and waste products caused by core-making and core-setting have been eradicated. (3) Dry sand molding without binder, moisture, and any additives is used to eradicate various casting defects and waste products caused by moisture, additives, and binders. (4) The sand treatment system is great...
