Mold for manufacturing catalyst

Abstract

The invention discloses a mold for manufacturing a catalyst. The mold for manufacturing the catalyst comprises an upper mold body and a lower mold body, wherein the upper mold body and the lower mold body are buckled. A plurality of longitudinal bars are respectively, correspondingly and evenly arranged in mold cavities along a longitudinal direction, wherein the cross sections of the longitudinal bars are in the shaped of isosceles trapezoids, and the width of the upper portion of the longitudinal bars is 2mm. A plurality of transverse bars are arranged among adjacent longitudinal bars at intervals by equant spaces along the longitudinal direction, wherein the cross sections of the transverse bars are arc-shaped. The upper surfaces of the transverse bars and the longitudinal bars are in the same horizontal plane. The chord height of the transverse bars is smaller than the depth of mold grooves formed among the longitudinal bars. A locking device comprises a trapezoidal board and two connection seats, wherein the trapezoidal board is arranged on the side wall of the upper mold and symmetrically provided with two through grooves and the two connection seats are arranged on the side wall of the lower mold body. Clamping boards matched with the trapezoidal board for use are hinged on the connection seats, and the trapezoidal boards and the connection seats are respectively provided with a pair of positioning through holes which are in opposite positions. The mold for manufacturing the catalyst has the advantages of being stable in structure, precise in positioning, and capable of further improving internal capacity of the mold and regularity of catalyst particles.

Description

technical field [0001] The invention relates to a mold, in particular to a molding mold for preparing catalysts. Background technique [0002] The activity of a catalyst depends not only on its chemical composition, but also on its organizational structure. The activity of the same catalyst is very different due to the difference of the molding die, so the molding die of the catalyst has special significance. Due to different molding dies, the specific surface area, pore size, particle and other physical properties of the catalyst will vary widely, resulting in a catalytic device, the overall surface area of ​​the catalyst loaded is small, and the particle size is irregular, which seriously affects the single-pass conversion rate and affects production revenue. The efficiency is affected, and it is time-consuming and labor-intensive, which affects work efficiency. Because the structure of the locking device of the usual mold is relatively simple and there is no positioning ...

Problems solved by technology

Due to different molding dies, the specific surface area, pore size, particle and other physical properties of the catalyst will vary widely, resulting in a catalytic device, the overall surface area of ​​the catalyst loaded is small, and the particle size is irregular, which seriously affects the single-pass conversion rate and affects production revenue. The efficiency is affected, and it is time-consuming and labor-intensive, which affects work efficiency. Because the structure of the locking device of the usual mold is relatively simple and there is no positioning device, it is easy to be damaged in the process of frequent mold opening, mold removal, and mold clamping, resulting in the mold clamping process. The occlusion of the upper and lower mold bodies is unreasonable, and the positioning is prone to deviation, which affects product quality and production efficiency
