Abstract

The invention discloses a quick forming device for an ultra-high molecular weight polymer. The quick forming device comprises a stock bin, a spray nozzle arranged at the bottom of the stock bin, a heating module and a heating cover.The heating module forms a heating area with the temperature gradually increasing from the top of the stock bin to the side with the spray nozzle, of the bottom of thestock bin, and the heating cover at least covers the spray nozzle, and a heating chamber is formed outside the spray nozzle. According to the quick forming device for the ultra-high molecular weight polymer, the ultra-high molecular weight polymer is heated to be in the molten state and subjected to extrusion forming; the quick forming device has the advantages of being large in adaptive temperature interval span, high in environmental adaptability and flexible and variable in printing forming structure; because three feeding chambers are formed in the stock bin, preheating, shrinkage temperature rise and small hole shrinkage accelerated extrusion of the solid or powdery ultrahigh molecular weight polymer in the stock bin are implemented; a rolling assembly is additionally arranged roll the ultra-high molecular weight polymer for solid bonding; and meanwhile, because the heating cover is arranged, it is guaranteed that the temperature in the space near the spray nozzle is stable.

Description

technical field

[0001] The invention belongs to the technical field of polymer material molding, and in particular relates to a rapid prototyping device for ultra-high molecular weight polymers. Background technique

[0002] 3D printing is a popular concept and a kind of rapid prototyping technology, which was born in the late 1980s. This technology integrates mechanical engineering, material engineering, numerical control technology, laser technology and other technologies, and uses the material accumulation method to manufacture the prototype of parts. The principle is to first model with computer-aided design (CAD) or computer animation modeling software to form a digital model, then decompose the three-dimensional model into two-dimensional cross-sections layer by layer, and accumulate and solidify the printing materials layer by layer through the software and numerical control system. Create physical products. The mainstream methods include Stereo Lithography Apparatu...
