Sand mold 3D printing sand mixing apparatus

Abstract

The invention relates to a sand mold 3D printing sand mixing apparatus. The sand mold 3D printing sand mixing apparatus comprises sand sucking pumps, sand storage tanks, a main body, a sand mixing tank and sand tanks, wherein the sand sucking pumps are fixedly arranged on the tops of the sand storage tanks, each sand storage tank comprises a sand inlet and a mass sensor arranged at the lower end of the sand inlet, the mass sensors are arranged on the main body, a control cabinet and a liquid material box support are fixedly arranged inside the main body, one end of the sand mixing tank is fixedly connected with each sand inlet through a control valve, the sand mixing tank is arranged inside the main body, motors are arranged at the other end of the sand mixing tank, the sand tanks are fixedly arranged at the end, close to the motors, of the sand mixing tank, a sand guide metal plate is arranged at the lower end of each sand tank, a vibration motor is installed on the side face of each sand guide metal plate, and a sanding device is fixedly arranged at the lower end of each sand guide metal plate through a control valve. The sand mold 3D printing sand mixing apparatus has the advantages that the problems of uneven mixing and sand leakage are solved, the working efficiency of a 3D printing apparatus is greatly improved, and meanwhile labor cost is reduced.

Description

technical field [0001] The invention relates to a sand-absorbing, sand-mixing and mixing ratio with liquid material mainly used in a sand mold 3D printer, in particular to a sand mixing equipment for sand mold 3D printing, which belongs to the field of 3D printers. Background technique [0002] Sand mixing equipment is an important auxiliary equipment for 3D printers, but there are many deficiencies in the existing sand mixing equipment. For example, the sand mixing equipment currently used in sand mold 3D printing equipment generally has a small capacity, which can only meet the printer of a single working box, and the internal mixing structure is single, and there is a hidden danger of uneven mixing. There is no seal at the sand outlet, and there is a hidden danger of sand leakage, which requires regular maintenance and treatment, which affects the working efficiency of its equipment. These problems have a strong impact on the working efficiency of 3D printers, so there i...

Problems solved by technology

For example, the sand mixing equipment used in sand mold 3D printing equipment generally has a small capacity, which can only meet the printer of a single working box, and the internal mixing structure is single, and there is a hidden danger of uneven mixing.

There is a lack of seal at the sand outlet, and there is a hidden danger of sand leakage, which requires regular maintenance and treatment, which affects the working efficiency of its equipment

These problems seriously affect the working efficiency of 3D printers, so there is an urgent need for a new sand mixing equipment in the market
