[0037] As a preferred solution, further, handles 4 are fixedly arranged at the central parts of the outer side walls of the baffle plates 21 to facilitate the application of force to the baffle plates 21.

[0038] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0039] Embodiment: According to the attached Figure 1-6 As can be seen, first, after fixing the bottom plate 11 in the load-bearing structure 1 on the corresponding workbench; by relatively assembling the baffle plates 21 in the polytype structure 2 to form a mold cavity, and after locking each two baffle plates 21 with a locking bar 23, then using a clamping bar 24 to limit the position of the locking bar 23 to prevent it from moving;

[0040] Then, pull the jacking rod 123 in the limiting component 12, so that the spring 126 is squeezed by the retaining piece 125 limited by the nut 124, and one end of the jacking rod 123 passes through the clamping frame 122 and is turned clockwise by 90 degrees for locking and limiting;

[0041] The assembled baffle plates 21 can be inserted into the limiting holes of the base through the limiting columns 22 to complete the installation, so that the connecting line of the included angle of one pair of the assembled baffle plates 21 coincides with the center lines of the left and right ends on the upper wall of the bottom plate 11, ensuring that the bottom plate 11 can seal the bottom of the space between the two pairs of baffle plates 21 to form a usable mold cavity;

[0042] Secondly, by rotating the tightening rod 123, the tightening rod 123, with the help of the spring 126, presses the nut 124 against the locking bar 23 for fixing between one pair of relatively assembled baffles 21 and presses it near the bottom position, so that the baffle 21 is fixed by means of the limiting post 22 under force (since the limiting posts 22 at the bottom of the relatively assembled baffles 21 are inclined relative to the upper wall of the bottom plate 11, they can be stable and immovable under force);

[0043] Then, after pouring the corresponding metal solution into the space between the baffles 21, the sealing plate 33 in the sealing die structure 3 passes through the claw 31 and is buckled above the baffle 21 for sealing. At the same time, the turning rod 32 is moved, and one end of it is inserted into the second card slot to limit the left - right movement of the sealing plate 33;

[0044] Finally, after cooling, the operation can be carried out in the opposite way to the above principle. After removing the sealing plate 33 and locking one of the tightening rods 123 on the holder 122, then, with the help of the clamping rod 24 on the locking bar 23, the two locking bars 23 whose relative connection lines are perpendicular to the center lines of the left and right ends of the bottom plate 11 are removed, and one pair of baffles 21 can be moved to achieve demoulding; or after both pairs of baffles 21 are separated from the bottom plate 11, demoulding can be carried out by separation.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
