Mold for graphite production

Abstract

The invention discloses a mold for graphite production, and belongs to the technical field of graphite processing. According to the mold for graphite production, the problems that an existing graphiteproduction die is difficult to replace and long in cooling time, die pressing fails due to die closing dislocation, and the pressure cannot be observed so that the die is damaged due to the fact thatthe pressure is too large are solved. The mold is characterized in that guide columns are correspondingly arranged on the front side and the rear side of the upper end surface of an outer mold, and fixing columns are correspondingly arranged on the left side and the right side of each guide column; a containing groove is formed in the center of the upper end of the outer mold, grooves are correspondingly formed in the left side and the right side of the containing groove, and a first saw tooth groove is formed in the center of the bottom of the containing groove; and a water flow channel is densely arranged in the side wall of the outer mold. According to the mold for graphite production, an inner mold is arranged, a hollow supporting plate arranged below the inner mold and a lifting rodcan be used for conveniently and rapidly replacing a mold, the fixing columns and the guiding columns on the outer mold can enable a mold pressing plate to be more smoothly and accurately pressed andprevented from dislocation, and after the mold pressing is finished, a spring in opening holes of the fixing columns push the mold pressing plate upwards due to the elasticity of elastic force, so that the mold taking is convenient.

Description

technical field [0001] The invention relates to a mold for graphite production, in particular to a graphite pressing mold, which belongs to the technical field of graphite processing. Background technique [0002] With the continuous progress and development of powder metallurgy technology, the application of pressure sintering is becoming more and more common. In order to ensure the quality of sintered products, graphite sintering molds are generally used to ensure the shape and sintering pressure. [0003] The traditional sintering mold adopts integral graphite, the product shape is taken out inside, and the lower pressure head is added for sintering; this method is time-consuming and laborious when changing the mold, and the mold will be damaged due to excessive pressure during pressing, and misalignment will occur when the mold is closed. Causes deformation of extruded items. Contents of the invention [0004] The purpose of the present invention is to provide a mold...
