Diaphragm filter plate mould pressing double-face forming equipment and forming method

Abstract

The invention relates to diaphragm filter plate mould pressing double-face forming equipment and a forming method, the diaphragm filter plate mould pressing double-face forming equipment can directly carry out mould pressing and forming to the diaphragm on double faces of the filter plate. The forming equipment comprises an upper die and a lower die, wherein the upper die is a cylinder-type upperdie of which the die cavity is a diaphragm forming cavity; the forming surface of the diaphragm forming cavity is a cylinder piston surface, and a cylinder piston is positioned in the upper die oil cavity; the lower die is a cylinder-type lower die of which the die cavity is a filter plate and a diaphragm forming cavity; the filter plate is positioned in the die cavity of the cylinder-type lower die; the forming surface of the diaphragm forming cavity is a cylinder piston surface; the cylinder piston is positioned in the lower die oil cavity; and the upper die oil cavity and the piston cavityare communicated by a transfer pipe and a hydraulic station. The invention has the advantages that both surfaces of the filter plate have equal stress, no flexural deformation generates as well as reliable sealing between the diaphragm and the filter plate can be ensured when the upper die and the lower die press the diaphragm; when used, the forming equipment does not have the phenomena of seepage and weeping between the diaphragm and the filter plate; the thickness of the diaphragm can be conveniently controlled by adjusting the movement amount of the piston in the upper die oil cylinder and the lower die oil cylinder.

Description

technical field [0001] The invention relates to a diaphragm filter plate molding double-sided molding device and a molding method for directly molding a diaphragm on both sides of the filter plate, and belongs to the field of diaphragm filter plate manufacturing. Background technique [0002] CN101249703, the name "molded diaphragm filter plate and forming method", the invention is a structure and forming method of directly molding the diaphragm on the core surface of the filter plate, which includes a filter plate core, and the filter plate core is put into the lower mold frame Inside, a degradable mold core is placed on the tympanic surface of the filter plate core, and then the plastic group after plastic is placed on the tympanic surface of the filter plate core, and then the upper mold and the lower mold frame are molded together, and it is formed after cooling Integrated single-sided plastic diaphragm filter plate, then turn the single-sided filter plate over and put i...

Problems solved by technology

Its disadvantages: when the mold is closed, the force on the filter plate core is uneven, it is easy to bend and deform, and it will affect the sealing degree between the diaphragm and the filter plate, and it will seep and leak when using the filter plate to filter
