A paraffin wax treatment system after demolding cavity molds for precision casting

Abstract

The invention relates to a de-moulded paraffin treatment system of a cavity mould for precision pressure casting. The de-moulded paraffin treatment system comprises a bottom plate, supporting side plates, a cleaning device and a carrying device, wherein the two supporting side plates are symmetrically mounted on the upper end surface of the middle part of the bottom plate; the cleaning device is mounted on inner side surfaces between the two supporting side plates; and the carrying device is mounted on the upper end surface of the bottom plate. The de-moulded paraffin treatment system can solve the problems that clear for paraffin in a cavity is incomplete when an existing cavity part performs precision processing and de-moulding, the requirements on the dimensions of to-be-flushed mouldsby the hoisting equipment are single, the residual paraffin in the mould cavity cannot be completely flushed, and the like, and can realize the function of automatically clearing the residual paraffinin the mould.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a paraffin wax treatment system after demolding of a cavity mold for precision casting. Background technique [0002] Precision casting refers to the general term for the process of obtaining precise size castings. Compared with the traditional sand casting process, the size of the castings obtained by precision casting is more accurate and the surface finish is better. It includes: investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting. In the process of precision casting for cavity molds, one step is dewaxing. Generally, after dewaxing, residual paraffin wax will adhere to the inner wall of the cavity mold, which will affect the next pouring step of the mold cavity. When cleaning the inner wall of the cavity mold, it is easy to scratch the inner wall, so that the precision casting cannot reach the required precision. There is no s...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a paraffin treatment system after the cavity mold for precision casting is demoulded, which can solve the problem of incomplete cleaning of paraffin in the cavity when the existing cavity parts are precision-processed and demolded The size of the mold that needs to be washed is single, and it is impossible to wash the residual paraffin in the cavity of the mold in an all-round way; it can realize the function of automatic cleaning of the residual paraffin in the mold, and has the paraffin in the cavity when the cavity parts are precision-processed and demoulded. The cavity is thoroughly cleaned, the hoisting equipment can adjust the size of the mold that needs to be rinsed, and the residual paraffin wax in the cavity of the mold can be rinsed in an all-round way, etc.
