Sand mixer capable of automatically filling sand according to casting model and automatic sand filling method thereof

Abstract

The invention discloses a sand mixer capable of automatically filling sand according to a casting model and an automatic sand filling method thereof. The sand mixer comprises a main base; the root ofa big arm is fixedly installed on the top of the main base through a first slewing support; in addition, a first speed reduction rack is also installed at the root of the big arm adjacent to the firstslewing support; a first servo motor with a power output shaft vertically downward is installed on the first speed reduction rack; a first pinion is installed on the power output shaft of the first servo motor; and the first pinion is engaged with an outer gear ring of the first slewing support. According to the sand mixer provided by the invention, a small arm sand outlet realizes the automaticmovement in the X-axis and the Y-axis directions, so that the sand mixer can perform automatic sand filling on a sand box according to the shape of the casting model, so that the sand adding speed isaccelerated, and manual operations are reduced.

Description

technical field [0001] The invention belongs to the field of resin sand casting production equipment, in particular to a sand mixer capable of automatically filling sand according to a casting model and an automatic sand filling method in the field. Background technique [0002] In the current foundry field, sand mixers are widely used in various self-hardening sand castings such as cast steel, cast iron, and non-ferrous metals. It can not only meet the requirements of single piece and small batch manual molding, but also can be used in core shooter and mechanized molding core production line. The raw sand of the sand mixer is continuously provided by the sand bucket, and the binder and curing agent are supplied by the liquid material pump. When the sand mixer is started, the raw sand and liquid material are supplied at the same time and mixed within a few seconds. The continuous flow out of the sand outlet directly flows into the sand box to fill it up, vibrate and compact...

AI Technical Summary

Problems solved by technology

According to the shape of the casting model in the sand filling process of the commonly used sand mixer, the worker needs to manually swing the forearm to fill the sand box with the mixed sand fully and without waste, but the speed of adding sand by manually swinging the forearm is slow. labor intensive
