Problems solved by technology

The second is that the assembly size between the diaphragm and the filter plate requires high precision, high processing costs, and time-consuming labor. Even so, the assembly of the diaphragm and the filter plate is affected by many factors such as its material, temperature, process, and processing accuracy. , It is sometimes difficult to achieve accurate assembly between the diaphragm and the filter plate, which directly affects the stability of product quality; third, in addition to the injection-molded diaphragm, the existing diaphragm is pressed by the diaphragm and the tolerance caused by the fusion and compression of the filter plate core after heating Due to the limitation of accumulated process conditions, the cavity thickness of the diaphragm cannot be made to be very consistent, which makes the space of the diaphragm filter cavity different in size, and it is easy to cause the pressure difference between the filter chambers during the filtration process, which may easily cause the rupture of the diaphragm filter plate and shorten the service life. Short; the fourth is the current planar structure of the diaphragm, no matter what the reason when the material in the filter chamber is not full, especially when there is little, when the tympanic membrane is pressed, it will be ruptured due to excessive stretching of the membrane

Embodiment 1

[0045] Embodiment 1: with reference to attached Figure 1-14 . High-efficiency and long-life multi-functional diaphragm and filter plate, which includes a filter plate core 1 and a diaphragm 2, the diaphragm 2 located on the filter plate core 1 is directly injection-molded on the filter plate core 1 using molds and injection molding equipment, and the shape of the diaphragm 2 is similar to that of the filter plate core. The shapes of the opposite filter plate cores 1 are corresponding. Filter plate core 1 refers to plastic plate core, metal plate core, adjustable temperature plate core, embedded plate core, non-embedded plate core; diaphragm 2 is embedded diaphragm, non-embedded diaphragm. Non-embedded diaphragms refer to flat, semi-enclosed, and all-inclusive diaphragms. The diaphragm is in the form of a unilateral diaphragm or a bilateral diaphragm. The thickness of the diaphragm depends on the thickness of the mold cavity or the injection molding process, which is a prio...

Embodiment 2

[0052] Embodiment 2: On the basis of Embodiment 1, the periphery or all surfaces of one or both surfaces of the filter plate core 1 are directly injected with the diaphragm 2 . The periphery refers to: the periphery of the core surface of the filter plate; the periphery of the side surface of the filter plate core; the combination of the periphery of the core surface of the filter plate and the periphery of the side surface of the filter plate core. All faces refer to all faces of the filter plate core and include inserts in the filter plate core, such as inlet and outlet fluid channels, etc.

Embodiment 3

[0053] Embodiment 3: On the basis of Embodiments 1 and 2, a diaphragm 2 and a filter plate core 1 form a tympanic membrane compressing chamber 3, and both the diaphragm 2 and the filter plate core 1 are made of thermoplastic materials.

Abstract

The invention relates to a structure of directly molding the membrane injection moulding on the filter pan and its molding method, it includes filter core, a filter core is put into the mould, directly injecting- moulding the fusion plastic on the one face or two faces or all faces of the filter core, and composing the membrane or membrane filter or filter pan. The merit: First, founding new structure and the new method in the filter board core directly; second, injection moulding the membrane and the filter pan, avoid drilling, two order scraps, bevel edge, deburring and so on crafts, saving the labor,and time,and has high efficiency, and the fitting grade and the seal reliability of the two reached to 100% initiated; third, realizing the ultra-thin, flexibility of the membrane thickness; fourth, using the release agent and anti-tack coat as the mold core of tympanic membrane squeezing cavity.

Description

technical field [0001] The invention relates to a structure and a molding method for direct injection molding of a diaphragm on the core surface of a filter plate, belonging to the field of diaphragm and filter plate manufacturing. Background technique [0002] 1. Injection molding process of filter plate: The applicant’s invention patent number is 2004100371135, titled “New Plastic Filter Plate or Plate Forming Process”, the new plastic filter plate or plate forming process, hot runner plastic filter plate forming mold or hot runner The hot runner opening of the plate forming mold is located on the upper or bottom or side of the hot runner plastic filter plate forming mold or the hot runner plate forming mold. The outlet of the injection mechanism of the injection molding machine is aligned with the hot runner opening, and the plastic raw material is heated and plasticized by the injection molding mechanism. Finally, the discharge port is injected into the cavity of the mol...
