Abstract

The invention discloses a die structure used for a moulded composite fiber material die and a manufacturing method thereof. The die structure mainly includes a glass-material inner die and an auxiliary fixture. The inner die includes an upper die and a lower die. An accommodating space is limited by the upper die and the lower die. The auxiliary fixture fixes the upper die with the lower die in a manner of clamping the upper die and the lower die. Because glass is a material which is easy to polish, an inner surface of the inner die is easy to be processed into a smooth surface in a manner of surface treatment, thereby enabling a product produced by the die to be high in surface precision without a secondary process.

Description

technical field

[0001] The invention relates to a mold structure, in particular to a mold structure for forming a composite fiber material mold, and also relates to a manufacturing method of the mold structure. Background technique

[0002] The shells of traditional electronic products are mostly made of engineering plastics or metals. However, with the increasing size of electronic products and the trend of consumers gradually pursuing light and thin, various new-generation materials have also begun to appear in various fields. on electronic products.

[0003] The shell of traditional electronic products is made by pressing in a metal mold, but because the surface of the mold cavity of the metal mold is not easy to polish, it is often a rough surface, causing the surface of the product made of the metal mold to be prone to irregularities. The smooth detailed structure is produced, so after the initial mold processing to make the prototype of the workpiece, the secondary pr...

Embodiment Construction

[0037] The preferred embodiment of the mold structure for forming composite fiber material molds of the present invention is as follows Figure 1 to Figure 3 As shown, the composite fiber material can be carbon fiber, glass fiber, basalt fiber, mineral fiber, boron fiber, Kevlar fiber or other man-made fibers. The mold structure includes: an inner mold 20 and an auxiliary fixture 30, wherein:

[0038] The inner mold 20 is made of glass material, and its inner surface is a smooth surface. The inner mold 20 includes an upper mold 21 and a lower mold 22. The periphery of the upper mold 21 has a first flange 211. There is a second flange 221 on the periphery of the mold 22, and the contour of the first flange 211 corresponds to the contour of the second flange 221, so that the upper mold 21 is closely attached to the lower mold by the first flange 211. 22 of the second flange 221, and make the upper mold 21 and the lower mold 22 jointly define an accommodating space 23, the accomm...
