Description
Technical field
The present invention relates to a kind of two-sidedly directly with two-sided diaphragm filter plate heating and mould pressing shaped device and the forming method of barrier film compression molding at filter plate, belong to membrane filter plate and make the field.
Background technology
CN101249703, title " die-pressing membrane filter plate and forming method ", this invention be a kind of on the filter sheet core face structure and the forming method with the direct compression molding of barrier film, it comprises filter sheet core, filter sheet core is put into low mold frame, eardrum face at filter sheet core is equipped with degradable core rod, then the plastics group behind the plastic cement is put into the one side of the eardrum face of filter sheet core, then with patrix and low mold frame matched moulds, namely constitute integrated single face plastic diaphragms filter plate after the cooling, then the single face filter plate is turned out and put into low mold frame, eardrum face at filter sheet core is equipped with degradable core rod, then the plastics group behind the plastic cement is put on the face of eardrum face of filter sheet core, with patrix and low mold frame matched moulds, namely constitute integrated two-sided plastic diaphragms filter sheet core after the cooling then.Its weak point: during matched moulds, the filter sheet core unbalance stress, easily flexural deformation, and can influence seal degree between barrier film and the filter plate can sepage when using filter to filter, leakage.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of at filter plate two-sided direct two-sided diaphragm filter plate heating and mould pressing shaped device and forming method with the barrier film compression molding.
Design: to achieve these goals.1, the piston area in cylinder type patrix and the cylinder type counterdie had been the design of barrier film mold pressing surface both, was one of technical characterictic of the present invention.The purpose of doing like this is: piston is packaged type patrix mold pressing surface and counterdie mold pressing surface in the cylinder type upper die and lower die, and the pressure that piston bears of the two equates, therefore the plastics when the upper and lower mould pressure surface is with plastic cement after are rolled into a ball when being embossed in filter plate two-sided simultaneously, the two-sided power of bearing of its filter plate equates, can avoid filter plate bend by pressure, fracture, has guaranteed that filter plate is indeformable, prolonged the service life of filter plate, and the automaticity height, easy to operate, high efficiency.2, the design of the interior electric heating tube of upper and lower mould (piston) is two of technical characterictic of the present invention.The purpose of doing like this is: during mold pressing, by temperature controller electric heating tube is controlled, can make upper and lower mould be in heated condition, thereby make the plastics group that is molded be in best moulded state, formed barrier film can seal fully reliably with formation around the filter plate, thus the generation of anti-impervious liquid, the phenomenon of leakage.
Technical scheme 1: two-sided diaphragm filter plate heating and mould pressing shaped device, it comprises upper die and lower die, described patrix is that the die cavity of cylinder type patrix and cylinder type patrix is the diaphragm forming chamber, the forming surface in diaphragm forming chamber is that oil cylinder piston face and oil cylinder piston are positioned at the patrix oil pocket, is provided with electric heating tube and electric heating tube in the forming surface of diaphragm forming chamber and is connected with the output of temperature controller by lead; Described counterdie is that the die cavity of cylinder type counterdie and cylinder type patrix is filter plate and diaphragm forming chamber, filter plate is positioned at the die cavity of cylinder type counterdie, the forming surface in diaphragm forming chamber is that oil cylinder piston face and oil cylinder piston are positioned at the counterdie oil pocket, and patrix oil pocket and plunger shaft are communicated with Hydraulic Station by petroleum pipeline.
Technical scheme 2: two-sided diaphragm filter plate heating and mould pressing forming method, filter plate two sides groove is built-in goes into the degradable core rod, plastics group behind the plastic cement is put on the cylinder type lower die face, to be equipped with that the filter plate that falls the touch core is simultaneously inserted in the cylinder type counterdie and touch mutually with plastics group behind the plastic cement, and then the plastics group behind the plastic cement inserted the filter plate another side, this moment, instruction energising heating back cylinder type patrix moved down, the plastics group that will be positioned at the filter plate two sides is pressed together on the two sides of filter plate, namely constitutes two-sided diaphragm filter plate after the cooling.
The present invention compares with background technology, and the one, the filter plate two sides is stressed to be equated, when descending stamped diaphragm thereon, neither can produce flexural deformation, can the pressure break filter plate yet, guarantee the positiver sealing between barrier film and the filter plate; In two uses sepage between barrier film and filter plate, the phenomenon of leakage can not take place; The 3rd, by adjusting the amount of movement of piston in the upper and lower mould oil cylinder, can control the thickness of made barrier film easily.
