Embodiment Construction
[0017] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0018] The high-temperature heat shield mould, comprising: upper mold base 1, lower mold base 2, as for upper splint 5 and lower splint 6 between upper mold base 1 and lower mold base 2, as for upper splint 5, lower splint 6 and The lower formwork 7 with the forming groove 701, the upper formwork 8 that closes the forming groove 701 between the lower formwork 7 and the upper splint 5, and the pressing assembly under the lower formwork 7 and corresponding to the forming groove 701. The pressing assembly includes: as for the nitrogen spring 9 under the forming groove 701 , as for the nitrogen spring pad 10 under the nitrogen spring 9 . The mold presses the material in the middle area, and the outside of the product is not stressed, which facilitates the flow of the material, and the material between the layers of the molding method is relat...

The invention discloses a high-temperature thermal shield die. The high-temperature thermal shield die comprises an upper die seat, a lower die seat, an upper clamping plate, a lower clamping plate, a lower die plate, an upper die plate and a pressing assembly, wherein the upper clamping plate and the lower clamping plate are arranged between the upper die seat and the lower die seat, the lower die plate is arranged between the upper clamping plate and the lower clamping plate and provided with a forming groove, the upper die plate is arranged between the lower die plate and the upper clamping plate and used for sealing the forming groove, and the pressing assembly is arranged on the lower die plate and corresponds to the forming groove in position. According to the die, pressed materials are stressed in the middle area, the outer side of a product is not stressed, and thus flowing of the materials is facilitated; by means of the forming mode, the materials among multiple layers are relatively stable, and the wrinkling and cracking phenomena are not prone to occurring.
Description
technical field [0001] A mold, particularly a heat shield mold. Background technique [0002] The high-temperature heat shield of the engine requires very good heat insulation effect and good heat absorption, so this kind of products need to use multi-layer composite materials; during the molding process of multi-layer composite materials, due to each layer The mechanical properties of the materials are different, and the method of pressing the edge cannot be used in addition, so the forming is very unstable; the prior art has not yet solved such a problem. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a mold where the material is pressed in the middle area and the outside of the product is not subjected to force, so that the flow of the material is facilitated, and the material between the multi-layers of the molding method is relatively stable, and it is not easy to Wrinkling and...
