Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . Diaphragm filter plate molding double-sided molding device, which includes an upper mold and a lower mold, the upper mold is an oil cylinder type upper mold 1 and the cavity 4 of the oil cylinder type upper mold 1 is a diaphragm forming cavity, and the forming surface 3 of the diaphragm forming cavity is The upper mold oil cylinder piston 12 faces and the upper mold oil cylinder piston 12 is located in the upper mold oil cavity 2; the lower mold is an oil cylinder type lower mold 7 and the mold cavity of the oil cylinder type lower mold 7 is a filter plate 6 and a diaphragm forming cavity, and the filter plate 6 is located in the mold cavity of the cylinder type lower mold 7, the forming surface 11 of the diaphragm forming cavity is the surface of the lower mold oil cylinder piston 9 and the lower mold oil cylinder piston 9 is located in the lower mold oil cavity 8, the upper mold oil cavity 2 and the lower mold oil ca...

Embodiment 2

[0010] Example 2: Membrane filter plate molding double-sided molding method, filter plate 6 grooves on both sides of the built-in degradable mold core 5, put the plastic mass on the surface of the cylinder type lower mold, and place the degradable mold core One side of the filter plate 6 of 5 is put into the cylinder-type lower mold and contacts with the plasticized plastic mass, and then the plasticized plastic mass is placed on the other side of the filter plate 6, and the cylinder-type upper mold 1 is commanded to move down, Press the plastic balls located on both sides of the filter plate 6 to the two sides of the filter plate 6, and form a double-sided diaphragm filter plate after cooling. The degradable mold core 5 is paper or hydrolyzed material or hydrolyzed release agent. The pressures bear between the upper die oil cylinder piston 12 and the lower die oil cylinder piston 9 are equal.

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...
