A jig-die two-in-one tool structure for a ring-shaped ceramic core
By designing a fixture and inspection tooling structure that combines a jig and an inspection tool for an annular ceramic core, the inner contour positioning block positions the annular ceramic core, and a shrinkage gap for the wax blank is reserved between the outer contour positioning block and the annular ceramic core. This solves the problem that the jig and inspection tool cannot be compatible at the same time, and achieves cost reduction and precision control.

AI Technical Summary
Technical Problem
In the current ceramic product manufacturing process, jigs and inspection tools cannot be used simultaneously, leading to increased mold development costs.
Method used
Design a fixture and jig combined into a tooling structure for annular ceramic cores. The inner contour positioning block positions the annular ceramic core, and a shrinkage gap of the wax blank is reserved between the outer contour positioning block and the annular ceramic core to realize the combination of the jig and the fixture.
Benefits of technology
This reduces the development costs of ring-shaped ceramic core fixtures and gauges, and improves production efficiency and precision control.

Abstract
A jig-detection two-in-one tool structure of a ring-shaped ceramic core comprises a bottom plate, an inner contour positioning block and an outer contour positioning block; the inner contour positioning block is arranged on the bottom plate; the outer contour positioning block is arranged on the bottom plate and is distributed around the outer circle of the inner contour positioning block; the outer circle of the inner contour positioning block is separated from the outer contour positioning block to form a positioning groove for accommodating the ring-shaped ceramic core; the outer side surface of the inner contour positioning block contacts the inner circle of the ring-shaped ceramic core; the outer contour positioning block is provided with a wax embryo shrinkage gap between the outer circle of the ring-shaped ceramic core; the proportion of the wax embryo shrinkage gap to the inner diameter of the positioning groove is c; the wax embryo shrinkage gap is used for accommodating the wax embryo of the ring-shaped ceramic core; the shrinkage rate of the ring-shaped ceramic core is a, the shrinkage rate of the wax embryo is b, and b≤c<a. The scheme reduces the cost of simultaneously developing the jig and the detection tool of the ring-shaped ceramic core to solve the problem that the jig and the detection tool of the existing ring-shaped ceramic core cannot be used simultaneously.
