A plurality of transverse bars are arranged between adjacent longitudinal bars at intervals along the longitudinal direction, and the cross section of each transverse bar is a circular arc. The upper surface of each transverse bar and the upper surface of each longitudinal bar are arranged on the same horizontal plane, and the chord height of each transverse bar is smaller than the depth of a die groove formed between each two adjacent longitudinal bars. The locking device comprises a trapezoidal plate and two connecting seats, wherein the trapezoidal plate is provided with two through grooves in a symmetrical mode and is arranged on the side wall of the upper die body, the two connecting seats are arranged on the side wall of the lower die body, the two connecting seats are respectively hinged with clamping boards which are matched with the trapezoidal plate, and the trapezoidal plate and the two connecting seats are respectively provided with a pair of locating through holes which are corresponding in position. The forming die for preparing the catalysts has the advantages of being stable in structure and accurate in location, and further improving internal capacity of the forming die and regularity of catalyst particles.

Description

Mould for the preparation of catalyst

Technical field

The utility model relates to a kind of mould, especially relates to a kind of mould for the preparation of catalyst.

Background technology

The activity of catalyst not only depends on its chemical composition, and is also relevant with its institutional framework.The same catalyst is due to the otherness of mould, and its activity falls far short, so the mould of catalyst has special significance.difference due to mould, the specific area of catalyst, pore size, the physical propertys such as particle can vary, thereby cause in a catalytic unit, the catalyst whole surface area of packing into is little, granular size is irregular, have a strong impact on conversion per pass, the Production Gain rate is impacted, and time-consumingly take a lot of work again, affect operating efficiency, because the locking device structure of common mould is simpler, there is no positioner, in frequent die sinking, form removal, easily damage in the locked mode process, cause the interlock of up and down die body in the locked mode process unreasonable, deviation easily appears in the location, affect quality and the production efficiency of product.

Summary of the invention

The utility model purpose is to provide a kind of mould for the preparation of catalyst, with the quality of implementation structure more stable and stronger, accurate positioning, raising catalyst prod and the purpose of production efficiency.

For achieving the above object, the utility model can be taked following technical proposals:

Mould for the preparation of catalyst described in the utility model comprises the upper and lower die body of mutual fastening; The distolateral wall of described upper and lower die body one is hinged, and other end sidewall is provided with locking device; Longitudinally correspondingly respectively in the die cavity of upper and lower die body be evenly equipped with the vertical muscle that many cross sections are isosceles trapezoid; Upper and lower die body die cavity bottom is respectively 8mm with the distance at edge; Between described adjacent vertical muscle longitudinally spaced set many sliver transvers sections are arranged is the horizontal bar of circular arc; The upper surface of described horizontal bar, vertical muscle is in same level; The action of horizontal bar is less than the degree of depth of formed mold slots between vertical muscle; Described locking device comprises and is arranged on the upper die body sidewall the symmetrical trapezoidal plate that has two grooves, is arranged on two Connection Blocks on the lower mold body sidewall; Be hinged with the clamp that is used in conjunction with described trapezoidal plate on described Connection Block; Have positioning through hole corresponding to a pair of position on described trapezoidal plate, Connection Block.

The utility model advantage be by in die cavity between adjacent vertical muscle longitudinally the many sliver transvers sections of spaced set be the horizontal bar of circular arc, the average decile of vertical muscle, make the catalyst granules of production more regular, stable; By mould being reinforced locking, Stability Analysis of Structures at the symmetrical clamp that has the trapezoidal plate of two grooves and be arranged on the lower mold body sidewall on the upper die body sidewall; By having positioning through hole corresponding to a pair of position in upper and lower die body edge, make that the mold integral structure is more stable, accurate positioning; Be further to increase the mould inside volume, change the distance at mold cavity bottom and edge into 8mm.
