Abstract

The invention discloses a vacuum mold made from epoxy resin compound materials, for preparing carbon nanotubes. The vacuum mold comprises an upper die, a middle die and a lower die, wherein a first concave table is arranged on the bottom surface of the upper die, a casting opening and an exhaust hole are formed in the first concave table, and the casting opening is connected with a storage bin through a casting valve; a second concave table is arranged on the top surface of the lower die; the middle die is positioned between the upper die and the lower die, the shape of the upper part of the periphery of the middle die is matched with that of the first concave table, the shape of the lower part of the periphery of the middle die is matched with that of the second concave table, an accommodating cavity is formed in the middle part of the middle die according to the shape of products, and the upper die, the middle die and the lower die jointly form a mold cavity. According to the vacuum mold made from the epoxy resin compound materials for preparing the carbon nanotubes, provided by the invention, the sealing property of the vacuum mold is improved, the interchangeability of the molds is improved, the demolding difficulty is reduced, and bubbles in finished products are decreased.

Description

technical field [0001] The invention relates to a vacuum mold for preparing carbon nanotube epoxy resin composite material. Background technique [0002] During the pouring of multi-walled carbon nanotube epoxy resin composite materials in the laboratory, the traditional gravity pouring method is mostly passive exhaust, so during the pouring process, bubbles and unevenness will be generated inside the composite material. Thereby reducing the quality of the casting. In addition, only the upper and lower molds are more difficult to demould, and the upper and lower molds are plane fit, and the sealing is not good. In addition, every time a new shape is changed, a set of molds must be made again, which is poor in interchangeability and expensive. Contents of the invention [0003] The object of the present invention is to provide a vacuum mold for preparing carbon nanotube epoxy resin composite material. In order to improve the airtightness of the vacuum mold, increase the ...
