Embodiment Construction

[0035] figure 1 It shows a foaming tool for processing that can be treated with foam or pre -foam plastic particles. Foaming tool 1 includes a part of an area 2 of an empty cavity 3 or a limited cavity 3. according to figure 1 The first embodiment shown in the area of ​​the empty cavity 3 includes a part of the surface structure 5 generated by the superposition method. According to the examples of this embodiment, surface structure 5 is produced by laser melting. Among them, surface structure 5, especially the powder -like building material that can be solidified by energy beam, through continuous layered selective exposure and continuous continuous continuous building material layer -related continuous continuous continuous continuous continuous Layered selective solidification and production. Of course, all other superimposed production methods can be used to produce foaming tools 1.

[0036] exist figure 1 In the embodiment of the foaming tool 1, the surface structure 5 can be...

Abstract

The invention relates to a foaming tool (1, 11, 17) for processing expandable plastic particles, having at least one region (2, 12, 19) forming at least part of a cavity (3, 13, 18) ), and at least one part (4, 14, 20) of the surface structure (5, 15, 21) of the region (2, 12, 19) forming the cavity (3, 13, 18), of which at least one part (4 , 14, 20) were produced by additive manufacturing methods.

Description

Technical field [0001] The invention involves a foaming tool for processing foaming plastic particles, including at least one area that forms an empty cavity. Background technique [0002] This foaming tool is well known in existing technology. The tool is used to produce or use the mold pressure parts composed of foam plastic particles (for example, as a mold pressure part). This type of molding machine includes at least one foaming tool, for example, they include two boards that can move and stay away from each other in a way similar to the way. This kind of foaming tool is formed by the cavity, and the cavity specifies the mold cavity that can make the foaming plastic particles formed. In the context of this application, the foaming tool can also be understood as a tool for forming an empty cavity. [0003] For production purposes, foamy and / or pre -pre -bubble plastic particles are introduced into the cavity, and their original volume is formed by expanding or expanding (such...
