Summary of the invention

 Design object: In order to avoid deficiencies in the background art, the present invention relates to a structure and a molding method for directly injection molding a diaphragm on a filter core surface, wherein:

 a) The diaphragm is directly injection molded on the filter core, which can reduce the appearance and dimensional accuracy and smoothness of the filter core, because the machining error of direct injection molding on the filter plate is almost zero tolerance, and wrapped in The dimensional accuracy and smoothness of the filter outside the filter plate core are reflected by the high precision of the mold processing. Therefore, the fit will be very close, and the appearance will be very smooth, because the thickness of the injection molding on the core of the filter plate is very thin compared with the entire area, and the heat shrinkage after processing is small, so the dimensional accuracy is high. And no need for secondary assembly, chipping, chamfering, deburring, manufacturing in and out fluid passages, etc.;

 b) making the film concave and corresponding to the shape of the filter plate, and the thickness of the filter cavity is relatively uniform, so that it can completely reduce the pressure difference of the filter chamber when the diaphragm is fully satisfied, reduce the breakage of the diaphragm, and greatly improve the service life thereof;

 c) Realizing the one-to-one correspondence between the shape of the diaphragm and the shape of the filter core, so that the filter core can be efficiently pressed regardless of whether the material is filtered or not, which greatly improves the quality and efficiency of the filtration and pressing;

d) It can be used to make filter plates, which can be suspended or inverted, or can be filtered by tympanic membrane or filtered by filter plates. Design Solution: In order to solve the deficiencies in the background art, the above-described design object of the present invention is achieved. The invention is designed in terms of structure:

 1) The diaphragm is directly injection molded on the filter element core, which is one of the main features of the present invention. That is to say, for the joint surface between the diaphragm and the filter element core, regardless of the structure of the joint surface thereof, the diaphragm has an integral injection-molded connection structure with the structure in the joint surface thereof. The purpose of this is to: Firstly, it is fundamentally unnecessary to consider whether the processing precision of the joint surface structure of the filter core can meet the requirements of the diaphragm assembly, without any roughing and finishing, as long as it is designed in the mold of the filter core It can be used in place, greatly reducing the manufacturing cost and improving the production efficiency, and improving the matching precision. Second, the combination sealing performance between the diaphragm and the filter plate is extremely high, which fundamentally solves the technical problems of the tympanic membrane leakage and leakage. The absolute parallel precision of the filter core is ensured, and the depth error of the tympanic press cavity is controlled to about 0.1 mm, which ensures the reliability of the product quality. Third, the cooperation between the diaphragm and the filter core is due to the absence of rework. Therefore, the matching accuracy reaches 100%, which has reached an unprecedented level. Fourthly, the appearance of the filter plate is improved, which not only helps to increase the flow rate of the filtrate, but also improves the working efficiency and is easy to clean.

2) The filter plate core is designed as a constant temperature filter plate, and the diaphragm is directly injection molded on the core surface of the controllable constant temperature filter plate, which is the second feature of the present invention. The effect and purpose between the diaphragm and the controllable thermostatic filter core have been involved in the above feature 1), and will not be described here. The purpose of designing the core as a thermostatic core with constant temperature function is as follows: Due to the different temperatures required, when the temperature is too low, for materials with poor fluidity or temperature sensitivity, the crystallization or viscosity in the material filtration caused by low temperature affects the filtration quality and efficiency; for some special materials, When the temperature is too high, it is impossible to ensure that the properties of the filtered material do not change, so it is necessary to filter at a constant temperature while satisfying the temperature. The invention adopts the core of the filter plate as a constant temperature core with constant temperature function, which is equivalent to a heating or cooling device. When heating is required, the inlet and outlet fluid ports of the thermostatic core and the outlet and inlet ports of the heat supply source Connected to form a loop, By controlling the size and temperature of the fluid, the temperature required for the thermostat core is met; when cooling is required, the inlet and outlet ports of the thermostat core communicate with the outlet and inlet ports that provide the cold source to form a circulation loop. Control the size and temperature of the fluid intake to meet the temperature required for filtration.

 3) The filter plate is designed as a heat dissipating filter plate, and the separator is directly injection molded on the surface of the heat dissipating filter plate, which is the third feature of the present invention. The effects and objectives between the diaphragm and the heat dissipating filter plate have been addressed in the above features 1) and 2) and will not be described here. The purpose of the metal plate core of the filter plate core of the invention is as follows: First, when processing high temperature and high pressure materials, the filter plate core has good heat deformation resistance performance, and can ensure the normal use and reusability of the filter plate core. Second, it has a heat-dissipating constant temperature function to ensure that the diaphragm and the filter core are in a relatively constant temperature state.

 4) The shape of the diaphragm corresponds to the shape of the opposite filter core or the temperature-controlled filter core or the heat-dissipating filter core, which is the fourth feature of the present invention. Since the surface of the filter plate core is generally concave, when the diaphragm and the surface of the filter plate core have a concave structure, the film surface elongation distance of the diaphragm tympanic membrane is much larger than the distance of the membrane tympanic membrane surface of the planar structure, which can generate very Good press filtration effect, especially when the filter material between the filter plates is insufficient, the effect of filtering and pressing can also achieve high efficiency, quickness, quality and quantity, and will not cause cracks or breakage of the diaphragm.

 5) Applying a release agent or a release layer to the tympanic press forming cavity surface of the filter element core is a feature of the present invention. The release agent or the release layer is disposed on the tympanic press forming cavity surface of the filter plate core, which is equivalent to the core, so that the plastic diaphragm injected onto the filter core is separated from the tympanic press cavity surface of the filter core. Forming a tympanic membrane press chamber. More importantly: the structure fundamentally realizes the precision of the tympanic membrane cavity and the expansion of the tympanic membrane.
