Problems solved by technology

Among them, the square sealing ring needs to be made by custom mold, and the production cost is high
In addition, the square sealing ring is severely worn during the frequent lifting of the forming platform, which easily leads to powder leakage. Therefore, it needs to be replaced regularly, which is inefficient and expensive

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the protection scope of the present invention.

[0019] image 3 A three-dimensional exploded view of the forming platform with the sealing device of the present invention is shown. like image 3 As shown, similar to the existing molding platform, the molding platform 1 with the sealing device of the present invention includes a molding platform lower board 15, a molding platform upper board 13 and a sealing device fixed on the upper surface of the molding platform upper board 13 printing platform12.

[0020] Among them, different from the existing forming platform using a square sealing ring for sealing, in the present invention, such as Figure 4 As shown, there is a circle of felt strips 18 around the lower plate 15 of the forming platform. A top plate 19 is respectively arranged around the in...

Abstract

The invention relates to a forming platform (1) with a sealing device, comprising a forming platform lower plate (15), a forming platform upper plate (13) and a printing platform (12), and a circle of felt is surrounding the forming platform lower plate (15). Strip (18), a top plate (19) is respectively provided around the inner side of the felt strip (18) and a rounded top block (17) is respectively provided at the four inner corners, and the periphery of the upper surface of the lower plate (15) of the forming platform A spring positioning plate (21) is respectively fixed and the spring positioning plate (21) is located in and corresponding to the top plate (19), and each top plate (19) and the corresponding spring positioning plate (21) are provided with a plurality of compression A compression spring (20) is also provided between the spring (20) and each rounded top block (17) and the spring positioning plate (21), and the forming platform upper plate (13) is fixed on the spring positioning plate (21). The sealing device has the advantages of simple structure, automatic compensation, good sealing performance, no need for frequent replacement and low cost.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and relates to a molding platform of nylon powder laser sintering equipment, especially a molding platform with a sealing device. Background technique [0002] The so-called 3D printing technology is a kind of rapid prototyping technology. It is mainly based on a mathematical model file in the format of STL. The mathematical model is sliced ​​by slicing software to generate code, that is, the printing path, and then controlled by the controller. Materials such as metal or plastic are used as raw materials, and objects are constructed layer by layer by heating and other means. [0003] As a kind of 3D printing technology, laser sintering molding uses nylon powder as the raw material. By controlling the scanning path of the laser, it can generate the shape of a certain cross-section of the object, and then use a scraper or powder spreading stick to push the plastic powder from the pow...
