Abstract

The invention provides a wax mould for impeller investment casting and can solve the problems that a wax mould of an existing impeller is high in development and manufacturing cost and long in cycle. The wax mould comprises a base and a plurality of sliding blocks, the base is uniformly provided with a plurality of sliding rails extending in the radial direction in the peripheral direction, and each sliding block is slidably installed between every two adjacent sliding rails. The wax mould is characterized in that each sliding block comprises a sliding block base body and a forming head, each forming head is provided with a wax mould forming cavity, and each forming head is detachably installed at the front end of the corresponding sliding block base body.

Description

technical field [0001] The invention relates to the field of investment casting, in particular to the field of impeller investment casting, in particular to a wax mold for impeller investment casting. Background technique [0002] Impellers are widely used in many industries, such as automotive turbochargers, centrifugal pumps, etc. With the diversification of product types, there are more and more types of impellers, which puts more and more demands on the product development cycle. demanding. [0003] Existing wax molds for impeller investment casting include several sliders, the front end of each slider is provided with a wax mold forming cavity surface, and several sliders are assembled into one body along the circumferential direction so that the wax molds at the front ends of each slider The surface of the forming cavity is combined into a wax mold forming cavity. By injecting melted wax into the wax mold forming cavity, the molten wax fills the entire wax mold formin...
