Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . Diaphragm filter plate 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 an oil cylinder piston surface And the oil cylinder piston is located in the upper mold oil chamber 2; the lower mold 7 is composed of a filter plate 6 and a lower mold oil cylinder, one side of the filter plate 6 is in contact with the piston 9 in the lower mold oil cylinder, and the other side is the mold surface of the lower mold; The upper mold oil chamber 2 and the piston chamber 8 communicate with the hydraulic station 10 through the oil delivery pipe. The four sides of the filter plate 6 are in contact with the table surface of the supporting boss of the cylinder wall of the lower mold. The surface of the piston 9 coincides with t...

Embodiment 2

[0010] Embodiment 2: Diaphragm filter plate molding method, filter plate 6 one side is put into the table top of the support boss of lower die oil cylinder cylinder wall, lower die oil cylinder works and makes piston 9 in the lower die oil cylinder face the groove surface of filter plate Put the degradable mold core 5 into the other side of the filter plate, then put the plasticized plastic ball on the degradable touch mold core 5, at this time, command the cylinder type upper mold 1 to move down, and press the heated plastic ball Combined with the other side of the filter plate 6, a single-sided plastic diaphragm filter plate is formed after cooling. The degradable mold core 5 is paper or hydrolyzed material or hydrolyzed release agent. The pressures bear between the piston 13 and the piston 9 are equal.

Abstract

The invention relates to a membrane filter board compression molding device and a molding method. The device comprises an upper mold and a lower mold, wherein the upper mold is an oil cylinder type upper mold, the mold cavity of the upper mold is a membrane molding cavity, and the molding surface of the membrane molding cavity is an oil cylinder piston which is positioned in an upper mold oil cavity; the lower mold comprises a filter board and a lower mold oil cylinder, one side of the filter board contacts with the surface of the piston in the oil cylinder, and the other side is the mold surface of the lower mold; and the upper mold oil cavity and a piston cavity are communicated with a hydraulic station through an oil pipe. The device has the advantages that both sides of the filter board are stressed equally, when the membrane is pressed by the upper mold, the membrane can not generate bending deformation, and the reliable seal between the membrane and the filter board is ensured; liquid seepage and leakage between the membrane and the filter board can not occur; and the thickness of the membrane can be conveniently controlled by adjusting the piston in the lower mold oil cylinder.

Description

technical field [0001] The invention relates to a diaphragm filter plate molding device and a molding method for directly molding a diaphragm on a filter plate surface, belonging 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 it into the lower mold frame, pl...
