Summary of the invention
For above-mentioned prior art present situation, technical problem to be solved in the utility model is, a kind of hollow fiber membrane cartridge casting mold is provided, and it can be realized different packed densities by plain mode, enters glue height, the cast of glue ring size filter core, to save repeatedly mold expense.Another technical problem to be solved in the utility model is, a kind of hollow fiber membrane cartridge pouring procedure that uses this casting mold is provided.
In order to solve the problems of the technologies described above, a kind of hollow fiber membrane cartridge casting mold provided by the utility model, comprising:
Die main body, is provided with charge groove; And
Built-in circle, can be positioned over described bottom, forms stairstepping cast chamber with described charge groove.
In an embodiment, described charge groove is circular trough therein, and described built-in circle is circular, and the internal diameter of the external diameter of described built-in circle and described charge groove matches.
In an embodiment, described die main body adopts surface to be prepared from by low hydrophobicity organic material therein.
In an embodiment, the hardness of described die main body is 30～90 degree therein.
In an embodiment, the material of described die main body is silicon rubber, fluorubber or fluoroplastics therein.
In an embodiment, described built-in circle adopts surface to be prepared from by low hydrophobicity organic material therein.
In an embodiment, the hardness of described built-in circle is 30～90 degree therein.
In an embodiment, the material of described built-in circle is silicon rubber or fluoroplastics therein.
Compared with prior art, hollow fiber membrane cartridge casting mold of the present utility model, because casting mold comprises die main body and built-in circle, die main body is provided with charge groove, built-in circle can be positioned over described bottom, form stairstepping cast chamber with described charge groove, therefore regulate filter core end face glue ring size, packed density, filter core to enter the object of the filter core preparation parameters such as glue height by regulating internal-and external diameter, the height size of built-in circle to reach, operability is flexible, can save repeatedly mold expense, and water the filter core form uniform specification outpouring.
The beneficial effect that the utility model additional technical feature has will describe in this description detailed description of the invention part.

Fig. 2 is the sectional structure schematic diagram of the built-in circle in one of them embodiment of the utility model;
Fig. 3 is that built-in circle is put into the sectional structure schematic diagram after the charge groove of die main body.
Description of reference numerals: 10, die main body; 11, charge groove; 12, inwall; 20, built-in circle.
Detailed description of the invention
Also the utility model is elaborated below with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in following embodiment and embodiment can combine mutually.
In one of them embodiment of the utility model, a kind of hollow fiber membrane cartridge casting mold is provided, as shown in Figures 1 to 3, hollow fiber membrane cartridge casting mold comprises die main body 10 and built-in circle 20, wherein, die main body 10 is provided with charge groove 11, and described built-in circle 20 can be positioned over described bottom, forms stairstepping cast chamber with described charge groove 11.Preferably, described charge groove 11 is circular trough, and described built-in circle 20 is circular, and the internal diameter of the external diameter of described built-in circle 20 and described charge groove 11 matches.Hollow fiber membrane cartridge casting mold is owing to having adopted this kind of structure, while carrying out filter core cast, can change by changing the internal diameter of different built-in circles 20 packed density of film silk, change filter core and enter glue height by changing the height of different built-in circles 20, thereby on the basis that does not change die main body 10, prepare flexibly different packed densities, enter the hollow fiber membrane cartridge of glue height, operability is flexible, can save repeatedly mold expense, and waters the filter core form uniform specification outpouring.
