Problems solved by technology

[0006] However, the known foaming devices for producing corresponding plate-shaped and other molded parts from plastic granules have the disadvantage that the duration of the production cycle is due to the necessary reversible temperatures of the tool and of the components to be produced. change and almost impossible to reduce
Another disadvantage is that the required energy requirements cause temperature alternations, especially due to the heat capacity of the templates.

Embodiment Construction

[0057] exist figure 1 An exemplary embodiment of a foaming device 01 according to the invention is schematically outlined in . First, the structure of the foaming device 01 can be seen, which has a surrounding formwork 04 and a roof formwork 05 on one side and the opposite multilayer structure 06 as a bottom formwork. The formwork 04 with the multilayer structure 06 forms the bottom-side tool part 03b, and the roof template 05 forms the roof-side tool part 03d, said 03b, 03d together enclosing the mold cavity 02, said 02 having a passage between the templates. The corresponding thickness of the space 08 formed between.

[0058] In contrast to the usual embodiments of the foaming device with a substantially solid formwork, the multilayer structure 06 has a multilayer construction, wherein in the exemplary embodiment there are also There are steam treatment openings 24 connected to a steam treatment facility 25 , ventilation openings 26 for creating a free passage to the surro...

Abstract

The invention relates to a device (01) having at least two tool parts (03, 53, 63) that can be separated in a dividing seam, wherein the closed tool parts (03, 53, 63) form a mould cavity (02, 52) ), within said mould cavity (02, 52), plastic particles can be foamed and / or expanded to produce foam-like mouldings. According to the invention, in particular in order to reduce energy consumption, the walls of the tool forming the mould cavity (02, 52) are at least partially formed by a multilayer structure (06, 56, 65) with a thin inner layer (11) ), the inner layer is mechanically supported by the support element.

Description

technical field [0001] The invention relates to an apparatus for producing foam-like molded parts, in particular acoustic panels. Background technique [0002] This foaming plant is used for the manufacture of all types of molded parts, especially when these are foamed from plastic granules. These include not only three-dimensional molded parts, but also plate-shaped molded parts, such as acoustic panels, in particular for the construction sector, for example in the form of acoustic panels for floors, facades and roofs. [0003] It is known from the prior art to produce plate-shaped molded parts in a separate process, in which plastics material is filled into a mold cavity formed by opposing substantially flat formwork plates and a surrounding formwork , followed by steaming, degassing and stabilization of the plastic material. As a result, a plate-shaped molded part corresponding to the geometry of the mold cavity is produced. [0004] In order to ensure the quality of t...
