Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . Double-sided diaphragm filter plate heating 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 It is the oil cylinder piston 12 surface and the oil cylinder piston 12 is located in the upper mold oil chamber 2, and the diaphragm forming cavity molding surface 3 is provided with an electric heating tube 13 and the electric heating tube 13 is connected to the output end of the temperature controller through a wire; the lower mold It is an oil cylinder type lower mold 7 and the mold cavity of the oil cylinder type upper mold 7 is a filter plate 6 and a diaphragm forming cavity, the filter plate 6 is located in the mold cavity of the oil cylinder type lower die 7, and the forming surface 11 of the diaphragm forming cav...

Embodiment 2

[0010] Example 2: Double-sided diaphragm filter plate heating molding device and forming method, the filter plate 6 is embedded in the grooves on both sides of the degradable mold core 5, the plastic ball after plastic is placed on the surface of the lower mold of the oil cylinder, and the One side of the filter plate 6 of the drop-touch mold core 5 is placed in the lower mold of the oil cylinder and is in contact with the plasticized plastic mass, and then the plastic mass is placed on the other side of the filter plate 6. The upper mold 1 of the formula moves down, and the plastic balls located on both sides of the filter plate 6 are pressed on the two sides of the filter plate 6, and the double-sided 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 12 and the piston 9 are equal.

Abstract

The invention relates a two-sided diaphragm filter plate heating and compression molding device and a molding method thereof for directly carrying out compression molding on a diaphragm on both sides of a filter plate. The device comprises an upper mold and a lower mold, wherein the upper mold is the cylinder type upper mold, and the mold cavity of the cylinder type upper mold is a diaphragm molding cavity; the molding surface of the diaphragm molding cavity is a cylinder piston surface, and a cylinder piston is positioned in the oil cavity of the upper mold; an electric heating pipe is arranged in the diaphragm molding cavity, and the electric heating pipe is connected with the output end of a thermostat through a conducting wire; the lower mold is the cylinder type lower mold, and the mold cavity of the cylinder type upper mold is provided with the filter plate and the diaphragm molding cavity; the filter plate is positioned in the mold cavity of the cylinder type lower mold; the molding surface of the diaphragm molding cavity is the cylinder piston surface, and a cylinder piston is positioned in the oil cavity of the lower mold; and the oil cavity and a piston cavity of the upper mold are communicated with a hydraulic pressure station through oil pipe lines. The device has the advantages that 1, both sides of the filter plate are equally stressed, and cannot be bent and deformed to ensure reliable sealing between the diaphragm and the filter plate; and 2, the device has no phenomena of liquid seepage and liquid leakage between the diaphragm and the filter plate during use.

Description

technical field [0001] The invention relates to a double-sided diaphragm filter plate heating molding device and molding method that directly molds 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 it i...
