Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

As shown in fig. 1-6 and 12, the mold for a chromatography column filter screen for biological extraction comprises a front plate 1, a front plate 2, a middle plate 3, a back plate 4 and a bottom plate 5 which are stacked in sequence and fixedly connected with each other. Each plate is provided with a counter bore 0 for connecting two adjacent plates.

The panel 1 is located the top, seted up first filling opening 11 on it, seted up first accepting groove 21 on the up end of front bezel 2, be equipped with first injection channel 22 on the front bezel 2 of first accepting groove 21 below, first injection channel 22 has many and is the form distribution of dispersing, it includes horizontal segment and vertical section, the axis of vertical section is parallel with the axis of first filling opening, set up a plurality of filling holes 31 that are linked together with first injection channel 22 on the medium plate 3, the injection direction of filling hole 31 is parallel with first filling opening 11, the second accepting groove 41 has been seted up on the terminal surface that back plate 4 and medium plate 3 laminated mutually, be equipped with the second injection channel 42 that the filling hole 31 is linked together on the back plate 4 of second accepting groove 41 below, filling hole 31 communicates second accepting groove 41 and first injection channel 22, be equipped with second filling opening 51 on the bottom plate 5.

Triangular notches 43 are formed in four corners of the end face, attached to the middle plate 3, of the rear plate 4, connecting holes 44 penetrating through the rear plate 4 are formed in positions corresponding to the notches 43 respectively, partial spaces of the connecting holes 44 are communicated with the notches 43, aligning holes 8 which are coaxial and of the same size as the connecting holes 44 in splicing are formed in the middle plate and the front plate respectively, and aligning blocks 9 are arranged in the aligning holes 8.
