Abstract

The invention provides a mold for molding a thermoplastic composite core mold. The mold comprises a mold lower part and a mold upper part, and a workpiece molding space is formed between the mold lower part and the mold upper part. The mold upper part is formed by splicing two detachable mold elements, and each of the detachable mold elements is provided with a molding face used for forming the workpiece molding space. According to the technical scheme of the mold for molding the thermoplastic composite core mold, after the die is installed, the workpiece forming space is filled with a formingmaterial after mounting the mold; and after the forming material is solidified, mold opening operation is conducted. Due to the fact that besides the lower mold part, the upper die part is formed bysplicing the two detachable mold elements, and each of the detachable mold elements is provided with the molding face used for forming the workpiece molding space, an adhesion acting force on the workpiece can be reduced by respectively detaching the two detachable mold elements; and therefore, demolding is relatively easy, and the problem that the workpiece is prone to damage due to the fact thatthe adhesion acting force is too large in the demolding process can be solved.

Description

technical field [0001] The invention relates to mold manufacturing, in particular to a mold for forming a core mold of thermoplastic composite material. Background technique [0002] In order to use the high strength and light weight performance of composite materials, the matrix material of most carbon fiber composite materials is mainly epoxy resin. Epoxy resins are generally liquid and become hard when cured. However, for some composite parts with complex cavities, if an ordinary hard mandrel is used, after the epoxy resin is cured, the mandrel inside the composite part will not be able to be demolded. [0003] In order to solve the above problems, deformable materials can be used to manufacture composite parts. The deformable materials can be carbon fiber reinforced resin matrix composites, where the resin matrix is ​​polymethyl methacrylate (PMMA) and epoxy resin (NPEF- 170) obtained by mixing in a certain proportion. Unlike pure PMMA used as a matrix to make thermop...
