Embodiment Construction

[0021] The technical solutions of the present invention will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A large vertical centrifugal casting machine model J5520B, the power of the main motor is 75kW, the maximum speed of the main shaft is 500rpm, and the speed can be adjusted steplessly. This equipment is suitable for single piece and small batch production. The size range of castings produced by this centrifugal casting machine: the maximum outer diameter is Ф2000mm, the maximum height is 500mm, and the load capacity of the centrifuge chassis is W (W 铸件 +W 铸型 ) within 10t.

[0023] Such as figure 1 The casting mold structure shown includes three parts: the base plate 4 , the cover plate 1 and the metal sleeve 2 , and the casting mold structure is positioned and locked on the chassis 5 of the vertical centrifugal casting machine. The mold structure is integrally locked on the centrifugal casting m...

Abstract

The invention belongs to the technical field of centrifugal casting and particularly relates to a casting mold structure and a base plate applicable to medium and large-scale vertical centrifugal casting machines. The casting mold structure and the base plate comprise baseboards, cover plates and metal sleeves. The baseboards have N models, a baseboard of each model corresponds to one cover plate of one model and a metal sleeve of one model, and the outer diameters of the baseboards, the cover plates and the metal sleeves of the same models are the same. The outer diameters of the baseboards of different models are different. Pressing plates have P models, and a pressing plate of each model corresponds to 1-2 cover plates of adjacent models. When an annular pressing plate of one model corresponds to two cover plates of adjacent models, annular outer radius of the pressing plate>=outer radius as 30mm of the cover plate of a corresponding larger model, and the inner radius of the pressing plate>=a pouring port step position outer end size as 30mm of the cover plate of a corresponding smaller model. The casting mold structure and the base plate have the advantages of forming a series of baseboards, cover plates and metal sleeves, enabling repeat use rate of the baseboards and the cover plates to be high, enabling the comprehensive cost price of a casting mold to be reduced, and simultaneously reducing production preparation periods.

Description

technical field [0001] The invention belongs to the technical field of centrifugal casting, and in particular relates to a mold structure and chassis suitable for large and medium-sized vertical centrifugal casting machines. Background technique [0002] Large and medium-sized vertical centrifugal casting machines have a wide range of applications. The outer diameter of castable castings for medium-sized vertical centrifugal casting machines is Ф400mm~Ф1000mm. The outer diameter of castable castings for large-scale vertical centrifugal There are two types of combination methods, one is composed of two parts, that is, the metal sleeve and the bottom plate are connected together and then the cover plate is formed, and the other is composed of three parts, that is, the base plate, the cover plate and the metal sleeve. No matter which kind of combined mold is suitable for a certain type of casting, the reusability is poor, and the cost of the mold is very high; the patent applic...
