Abstract

The invention provides an embedded and buckled type wax mold forming method which comprises the following steps that firstly, the shape of a target part is obtained, the target part is divided into at least two sub-parts, the two sub-parts are spliced to form the target part, a clamping protrusion and a clamping groove which correspond to each other in shape are arranged on the splicing faces of every two adjacent spliced sub-parts correspondingly, according to the shape of the sub-parts, a mold is processed and prepared, sub-wax molds consistent with the sub-parts in shape are prepared according to the obtained mold, and the sub-wax molds are spliced through the clamping protrusions and the clamping grooves on the sub-wax molds, so that an embedded and buckled type wax mold is obtained. The invention provides the brand new wax mold forming method, the forming difficulty of the wax mold with a complex cavity structure can be remarkably reduced, meanwhile, the process is simple, and the method has a good application prospect.

Description

technical field

[0001] The invention relates to the technical field of casting technology, in particular to an embedding type wax mold forming method. Background technique

[0002] Investment casting can produce small and medium structural parts of any complex shape.

[0003] For wax mold products with hollow and complex inner cavity structure, the existing molding methods are mainly divided into two types. The first one is to use the soluble core as the internal support and cooperate with the soluble core and the outer mold. After pouring to form a wax mold, put the wax mold with a soluble core into cold water, and a complete wax mold can be obtained after the core is dissolved. It can be seen that the process first needs to prepare a soluble core, and also Including the subsequent core dissolution and drying process, the process steps are cumbersome; the second is to split the core structure of the wax mold into several small cores, and several small cores are required to...
