A multi-ring thin-wall mold for simulating centrifugal casting

Abstract

The invention discloses a multi-ring thin-wall mold for simulating centrifugal casting. The multi-ring thin-wall mold comprises a base plate, a pouring cup, a pouring passage and a casting mold, wherein the base plate is in a round flat plate shape, the pouring cup is arranged in the circle center part of the base plate, the casting mold is fixedly arranged on the bottom disc, and is in an annular post shape, the annular circle center of the casting mold is coincident with the circle center of the bottom disc, the pouring passage is fixedly arranged on the bottom disc and is used for communicating the pouring cup and a cavity of the casting mold, and the height of the pouring passage is smaller than the height of the casting mold. In the use process, fluid entering the mold through the pouring cup reaches the cavity through the pouring passage via the centrifugal force, and can be further injected into the cavity from outside to inside and from lower side to upper side for realizing the metal liquid mold filling process simulation. The device has the advantages that the fluid three-dimensional form flowing process can be simulated, and reasonable simulation test data can be obtained.

Description

technical field [0001] The invention belongs to the field of centrifugal casting, and more specifically relates to a multi-ring thin-walled centrifugal casting mold used for simulation experiments. Background technique [0002] Centrifugal casting can make the gas and slag in the liquid metal move from the outside to the inside under the action of centrifugal force and discharge, so that the castings rarely have defects such as shrinkage cavities, shrinkage porosity, slag inclusions and pores. It is widely used in the production of sleeves, thin Ring castings such as walls. [0003] The change of various process parameters in the centrifugal casting process and the drastic change of the free surface in the liquid metal filling process all affect the forming quality of the casting. In order to know the changes of various process parameters in the centrifugal casting process and the drastic changes in the free surface of the liquid metal filling process, etc., real experiment...

AI Technical Summary

Problems solved by technology

However, in order to simplify the simulation, the mold is limited to the mold design of the small planar structure, which is suitable for studying the free surface of the liquid two-dimensional plane, but the actual metal liquid filling process is a complex three-dimensional flow pattern

Therefore, the mold of this small planar structure is not suitable, and correspondingly, no reasonably useful data can be obtained
