Novel vertical-type centrifugal casting machine

Abstract

The invention provides a novel vertical-type centrifugal casting machine which comprises a feeding hopper, a rotating mechanism, an air cylinder, an upper pressing plate and a lower pressing plate. An inner cavity of the feeding hopper is communicated with a space under the upper pressing plate, and the upper end of a piston rod is supported at the bottom of the lower pressing plate in a jacking mode and connected with the lower pressing plate through a second bearing; the rotating mechanism comprises a motor, a driving wheel, a driven wheel and a belt, and the top of the upper pressing plate is provided with a rotation shaft. According to the novel vertical-type centrifugal casting machine, the rotating mechanism and the air cylinder used for lifting are separated and arranged to be connected with the upper pressing plate and the lower pressing plate respectively, when the rotating mechanism drives the upper pressing plate to rotate, the piston rod of the air cylinder is in a static state, therefore, the motor does not need to drive the air cylinder to rotate, and the energy consumption in the casting process can be reduced; in addition, due to the static state of the air cylinder, it can be guaranteed that the upper pressing plate, the lower pressing plate and a mould between the upper pressing plate and the lower pressing plate rotate steadily and efficiently to fully supply centrifugal force needed by casting, the casting precision is improved, and the quality of casting products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a novel vertical centrifugal casting machine. Background technique [0002] Centrifugal casting is a casting method in which liquid metal is poured into a rotating mold to complete filling and solidification under the action of centrifugal force. [0003] The publication number is CN102773444A, and the Chinese patent whose publication date is 2012-11-14 discloses a vacuum centrifugal casting machine, including a frame, a centrifugal bucket and a bucket cover; Between the pressure plate and the lower spinning plate, the lower spinning plate is set on the top of the vertically arranged rotating shaft, the bottom end of the rotating shaft is set on the cylinder, and the cylinder is set on the frame; the rotating shaft is set on the driven wheel so that it can slide relatively, The driven wheel is connected to the driving wheel through a belt, and the driving wheel is conn...
