Description
Technical field
The invention belongs to Filter Press technical field, especially a kind of quadric injection mould processing filter plate squeeze diaphragm sheet.
Background technology
Diaphragm includes that pressure-bearing frame and chip, pressure-bearing frame are mainly used in sealing, and therefore needs the material higher by hardness
Make；Chip is mainly used in press dewatering, therefore needs the highly elastic material with deflection is bigger to make.
The pressure-bearing frame of the diaphragm sold in the market and chip use same material to make, in order to ensure product
Sealing, selects the material that hardness is higher as the raw material of diaphragm, has so given up aeroelastic requirements necessary to chip, made
Pressure and deflection when obtaining diaphragm squeezing are limited by very large.The another kind sold on market is to be inlayed by diaphragm
On central layer, this mosaic mode diaphragm easily comes off and interchangeability is poor, therefore uses condition and life-span to receive the biggest
Limit.
Summary of the invention
The technical problem to be solved is to provide a kind of quadric injection mould processing filter plate squeeze diaphragm sheet, pressure-bearing limit
Frame and chip select different materials to make, and are integrated by secondary injection molding, it is ensured that the hardness needed for pressure-bearing frame with
And the elastic deformation amount needed for chip, meet respective demand.
For solving above-mentioned technical problem, a kind of quadric injection mould processing filter plate squeeze diaphragm sheet that the present invention provides, it includes
Pressure-bearing frame and chip, described pressure-bearing frame and chip be integrated by twice injection mo(u)lding, and the hardness of described pressure-bearing frame is high
In the hardness of chip, described pressure-bearing frame, pressure-bearing frame and chip fusion be provided with boss, the side of described boss is wave
Shape, the top of boss is circular arc, chip be provided with boss with the use of groove.Fused longitudinally of boss and groove is i.e.
For waveform fusion face.
The pressure-bearing frame of diaphragm is first designed according to the requirement of heat seal process, by compacting with the raw material that hardness is higher
Or injection mo(u)lding, then puts into inside injection mold by pressure-bearing frame, by resilient materials softer for hardness by injection side
Formula is molded in mould, and the pressure-bearing frame material making the chip of elastomeric material and hardness higher fuses into and is integrally formed diaphragm,
Make diaphragm both have the pressure-bearing frame of high rigidity and intensity, there is again the elastic and extraordinary inside chip of displacement performance, should
Diaphragm can either sustain bigger sealing surface pressure, in turn ensure that internal bigger displacement deformation thus overcomes the highest pressure
Squeeze power.
As preferably, described chip near with the side of pressure-bearing frame fusion before and after face be equipped with staged boss.Make
Chip bulk deformation gradually limits its root deformation amount while increasing, it is to avoid fracture of root, the root of its chips leans on exactly
The side that near and pressure-bearing frame fuses.
As preferably, four corners of described pressure-bearing frame are provided with liquid outlet.
After using above structure, a kind of quadric injection mould of the present invention processes filter plate squeeze diaphragm sheet compared with prior art,
Have the advantage that 1, pressure-bearing frame and chip select unlike material to make respectively, meet respective hardness requirement and deformation
Demand；2, strainability is greatly improved；3, extended service life；4, effectively prevent use condition to be subject to
The problem limited；5, processing technology is different from existing technique, it is achieved that in filter plate technical field, unlike material is fused together
Technical barrier.

Fig. 2 is that the B in Fig. 1 is to sectional view.
Wherein: 1, pressure-bearing frame, 2, chip, 3, waveform fusion face, 4, staged boss, 5, liquid outlet, 6, circular arc
Shape.
Detailed description of the invention
The invention will be further described to combine accompanying drawing below by embodiment.
As shown in Figure 1-2, a kind of quadric injection mould processing filter plate squeeze diaphragm sheet that the present embodiment provides, it includes pressure-bearing limit
Frame 1 and chip 2, described pressure-bearing frame 1 and chip 2 be integrated by twice injection mo(u)lding, and the hardness of described pressure-bearing frame 1 is higher than
The hardness of chip 2, on described pressure-bearing frame 1, pressure-bearing frame 1 be provided with boss with chip 2 fusion, the side of described boss is ripple
Shape wave, the top of boss is circular arc 6, chip 2 be provided with boss with the use of groove, this kind of frame mode ensures boss
It is waveform fusion face 3 with fused longitudinally of groove, so that pressure-bearing frame 1 and chip 2 fused portion ensure maximum fusion
Area, increases fusion intensity, described chip 2 near with the side of pressure-bearing frame fusion before and after face be equipped with staged boss 4,
Chip bulk deformation is made gradually to limit its root deformation amount while increasing, it is to avoid fracture of root.
Four corners of described pressure-bearing frame 1 are provided with liquid outlet 5.
The pressure-bearing frame of diaphragm is first designed according to the requirement of heat seal process, by compacting with the raw material that hardness is higher
Or injection mo(u)lding, then puts into inside injection mold by pressure-bearing frame, by resilient materials softer for hardness by injection side
Formula is molded in mould, and the pressure-bearing frame material making the chip of elastomeric material and hardness higher fuses into and is integrally formed diaphragm,
Make diaphragm both have the pressure-bearing frame of high rigidity and intensity, there is again the elastic and extraordinary inside chip of displacement performance, should
Diaphragm can either sustain bigger sealing surface pressure, in turn ensure that internal bigger displacement deformation thus overcomes the highest pressure
Squeeze power.
