Abstract

The invention discloses a medium-fine-particle graphite product hot-press forming device capable of improving the compactness of paste. The medium-fine-particle graphite product hot-press forming device comprises a machining table and a portal frame, the portal frame is installed at the top end of the machining table, a top plate is riveted to the top end of the portal frame, the portal frame is sleeved with a moving plate, an air cylinder is fixedly connected to the top end of the top plate, and a piston rod is arranged at the output end of the air cylinder, penetrates through the interior of the top plate and extends to the position below the top plate. According to the medium-fine-particle graphite product hot-press forming device capable of improving the compactness of the paste, an inner cavity, a hot-press module, an upper die base and connecting rods are arranged, the bottom end of the hot-press module makes continuous contact with and extrudes a product, all the hot-press module is pressed on the product till the top end of the hot-press module is contracted into the inner cavity, the upper die base continues to press downwards, the product is subjected to the superposed pressure of the inner cavity and the hot-press module, a movable plate continues to move downwards till the bottom surface presses the upper die base, so that the product is subjected to the three-time superposed pressure, the downward pressure is gradually increased, and the problem of poor compactness is solved.

Description

technical field [0001] The invention relates to the technical field of graphite product production, in particular to a hot-press molding device for fine-grained graphite products that can improve the compactness of paste. Background technique [0002] Graphite is a simple carbon element widely used in the manufacture of fine products such as electrodes, graphite fibers, and electric brushes. It has the advantages of high temperature resistance, good electrical and thermal conductivity, and strong plasticity. This kind of carbon paste has a soft texture and can be used as raw material for graphite products. It is evenly stirred by a kneading pot, and the temperature is lowered to 110-140°C to achieve a certain cohesive force. The cooling material is evenly loaded into the mold, and the vacuum degree reaches below 0.095MPa. After that, the press is used for hot-compression molding, and different molds are used to press it into the required shapes and patterns of graphite rings...
