Residual material self-receiving type 3D (three-dimensional) printer for conformal cooling water channel of mold

Abstract

The invention relates to a residual material self-receiving type 3D (three-dimensional) printer for a conformal cooling water channel of a mold. The residual material self-receiving type 3D printer comprises a molding frame and a laser emitting mechanism, wherein a molding lifting groove is formed in the inner side of the molding frame and is matched with a molding lifting cylinder; the molding lifting cylinder comprises a molding bottom plate and molding side plates located in the molding lifting groove; the molding bottom plate is connected to a molding lifting device arranged at the bottomof the molding frame; the molding side plates at the left side and right side comprise side plate cavity blocks; cavity opening and closing devices are arranged at the inner sides of the side plate cavity blocks; discharge holes which communicate with the side plate cavity blocks and tilt inwards and downwards are formed in the molding bottom plate; discharge guide cylinders which are matched withthe discharge holes and are in the shape of an inverted cone are arranged below the molding bottom plate; and scraping devices are arranged at the left side and right side of the upper part of the molding frame, can penetrate into the interior of the molding frame and are matched with the positions of the cavity opening and closing devices. The 3D printer is of a cylinder lifting structure, can collect excess powder into the lower part of the molding frame, realizes the collection of the excess metal powder and saves the floor space.

Description

technical field [0001] The invention relates to the field of mold conformal cooling water channel forming equipment, in particular to a 3D printer of a self-collecting mold conformal cooling water channel. Background technique [0002] The mold is called the mother of industry. The conformal cooling technology proposed in the 1990s, the water channel changes according to the shape of the product, can achieve uniform cooling, can significantly improve the quality of the product, reduce the cooling time, and has strong applicability. [0003] Although conformal cooling has incomparable advantages over traditional cooling channels, it is difficult to achieve with traditional processing methods, which limits the application of conformal cooling to a certain extent.

[0003] Although conformal cooling has incomparable advantages over traditional cooling channels, it is difficult to achieve with traditional processing methods, which limits the application of conformal cooling to a certain extent. With the emergence of 3D printing technology, SLM (Selective lasermelting) 3D molding is very suitable for the molding of conformal molds. SLM3D molding uses layer-by-layer molding, which can be suitable for various complex structural moldings. Most of them include molding lifting blocks and laser emitters that can emit lasers at any position. The laser is controlled by the controller. The laser melting area of ​​the emitter, and then realize the molding of complex shapes. In the process of metal powder feeding and laying, there will be indispensable metal powder residues, which need to be scraped out by scraping devices. Most of the existing 3D printers The remaining material collection device will be installed outside the city, which increases the cost of residual material collection and the overall occupied area of ​​the equipment
