Multifunctional double-printing-head 3D printing equipment based on 3DP technology

Abstract

The invention discloses multifunctional double-printing-head 3D printing equipment based on the 3DP technology in the field of 3D printing equipment. The equipment comprises a first feeding hopper and a second feeding hopper, the first feeding hopper and the second feeding hopper are arranged on a rack, a first mixing bowl is arranged below the first feeding hopper, a second mixing bowl is arranged below the second feeding hopper, a powder spreading device is arranged below the first mixing bowl and the second mixing bowl, a working box is arranged below the powder spreading device, and a lifting platform is arranged in the working box. A first feeding opening and a second feeding opening are formed in the two ends of the powder spreading device respectively, the first feeding opening corresponds to the first mixing bowl, and the second feeding opening corresponds to the second mixing bowl. The powder spreading device is arranged on a powder spreading device guide rail, a printing head guide rail is arranged above the powder spreading device, a first printing head and a second printing head are arranged on the two sides of the printing head guide rail, and the orthographic projection trajectory of the powder spreading device, the first printing head and the second printing head covers the whole lifting platform in the moving process. In the working process, the first printing head or the second printing head can be selected for working, a sand mould can be printed out, a mould also can be printed out, the equipment can achieve two purposes, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to a 3D printing device, which is mainly used for printing casting sand molds and printing casting molds. Background technique [0002] The current 3D printing equipment, the printing material can be sand, plastic powder or metal powder, but because only one set of printing head is configured, the same equipment can only print the same material, so the scope of use of the equipment is greatly limited. Contents of the invention [0003] The purpose of the present invention is to provide a multi-functional dual-print head 3D printing device based on 3DP technology, equipped with dual print heads, which can print two materials of sand and plastic powder, one machine with two uses, improving production efficiency and saving equipment costs, for The application of 3D printing technology in the foundry industry provides more favorable conditions. [0004] The object of the present invention is achieved in the following way: 1. A 3D p...
