Embodiment

[0041] The invention provides a molding die for forming composite material components with different thicknesses, which includes a top plate 1, a demoulding screw 2, a punch 3, an ejector rod 4, a pressing block 5, an inner hexagonal screw 6, a die 7, and a support column 8. Support plate 9, base plate 10, hoisting ring 14.

[0042] Among them, the mold adopts the upper and lower half structure.

[0043] The top plate 1 is a flat plate structure, on which there are 4 hoisting threaded holes 13 for installing hoisting rings 14; 4 connection positioning holes 12 for installing demoulding screws 2; 11.

[0044] The demoulding screw 2 is a slender cylindrical structure with a screw thread at one end and is connected with the base plate 9; the other end is a rectangular block structure and is provided with an undercut for convenient installation.

[0045] The punch cavity structure of the punch 3 has a taper, and is provided with a threaded connection hole 11 for connecting with ...

Abstract

The invention aims to provide a universal compression moulding mould for forming flat plate type composite material components with large sizes and different thicknesses. The universal compression moulding mould comprises a top plate, demoulding screws, a male mould, ejection rods, a pressing block, a female mould, supporting columns, a supporting plate, a bottom plate, inner hexagonal screws, hoisting rings, connecting positioning holes, hoisting threaded holes and threaded connecting holes. According to the universal compression moulding mould for forming the flat plate type composite material components with the large sizes and the different thicknesses, an upper-lower bipartition structure is adopted so that continuous operation of packing, mould pressing and demoulding of a pluralityof products can be realized; and for solving the problem that production efficiency is low in the forming process and the demoulding process of large-size products, a connecting rod type automatic demoulding structure is adopted, so that the hoisting operation process and circulation operation on different equipment are omitted, production efficiency is improved by 30%, safety is improved, and product size precision is improved.

Description

technical field [0001] The invention relates to a mold suitable for forming composite material components, in particular to a general compression molding mold for forming large-sized flat-plate composite material components with different thicknesses. Background technique [0002] The composite material component is a flat plate structure, which is cured and molded by prepreg layup molding. The product requires high resin content, smooth surface of the part, no flash, burr, hole, delamination and other quality problems. To ensure that there is no defect inside the product, the flatness accuracy is 0.1mm, and the product with double-sided smooth surface is directly molded, with sufficient rigidity and strength to ensure that there is no damage during mold closing and demoulding. Comprehensive consideration should be taken in mold design Various factors such as the mechanical properties and thermal properties of the mold material, optimize the selection of the mold structure a...
