Connecting rods 11 are fixedly installed on the sides of the two limit plates 12. One ends of the two connecting rods 11 pass through the rectangular grooves 9 and are fixedly connected to the sides of the corresponding L-shaped blocks 7. The surfaces of the two connecting rods 11 are sleeved with first return springs 10, one end of the first return spring 10 is fixedly connected to the wall of the rectangular groove 9, and the other end of the first return spring 10 is fixedly connected to the side of the limit plate 12.

[0020] Threaded push rods 3 are threadedly connected to both sides of the fixing plate 1 , and one end of the threaded push rod 3 is in contact with the other side surface of the limiting plate 12 .

[0021] Specifically, the movement of the limit plate 12 is controlled by the cooperation of the threaded push rod 3 and the first return spring 10 , and the movement of the limit plate 12 drives the movement of the L-shaped block 7 , thereby facilitating the engagement and separation of the L-shaped block 7 and the T-shaped slot 6 .

[0022] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing mechanism includes four T-shaped fixing columns 14, a mounting groove 16 is opened in the middle of the positioning column 5, and T-shaped fixing columns 14 are inserted and connected at both side corners of the mounting groove 16. Two fixing holes 13 are opened on both sides of the inner wall of the positioning hole 4, and the T-shaped fixing columns 14 are nested and connected with the fixing holes 13. The surface of the T-shaped fixing column 14 is sleeved and connected with a second return spring 15, one end of the second return spring 15 is fixedly connected to the groove wall of the mounting groove 16, and the other end of the second return spring 15 is fixedly connected to the side of the T-shaped fixing column 14.

[0023] A rotating shaft 17 is rotatably connected between the top and bottom ends of the mounting groove 16 , and a bidirectional cam 20 is fixedly installed at the aligned position between the rotating shaft 17 and the T-shaped fixing column 14 . Both ends of the bidirectional cam 20 are in contact with the end faces of the corresponding T-shaped fixing column 14 .

[0024] One end of the rotating shaft 17 passes through the mounting groove 16 and extends to the outside to be fixedly mounted with a rotating block 18 . A cross-shaped slot is opened at the center of the rotating block 18 . A positioning pin 19 is inserted and connected between the rotating block 18 and the positioning column 5 .

[0025] Specifically, the rotating block 18 rotates to drive the rotating shaft 17 to rotate, and the rotating shaft 17 rotates to drive the bidirectional cam 20 to rotate. The bidirectional cam 20 squeezes the two T-shaped fixing columns 14 and the fixing holes 13 to intersect and fix them, thereby improving the firmness of the installation of the injection mold 2.

[0026] Working principle: The utility model provides an installation structure of an injection mold. When installing the injection mold 2, firstly rotate the threaded push rod 3 in the forward direction, and the threaded push rod 3 pushes the movement of the limit plate 12, and the movement of the limit plate 12 drives the connecting rod 11 to push the L-shaped block 7 to move, so that the L-shaped block 7 moves to the middle, and then the injection mold 2 is hoisted to the fixed plate 1 to align the position, and the T-shaped slot 6 opened on the back of the injection mold 2 is embedded with the L-shaped block 7, and the four positioning columns 5 are interlaced with the positioning holes 4 opened at the four side feet of the injection mold 2, and then the threaded push rod 3 is manually loosened, and the L-shaped block 7 is fixed with the T-shaped slot 6 by the reset force of the first reset spring 10;

[0027] Then, the rotating block 18 is rotated manually through a cross, and the rotating shaft 17 is driven to rotate by the rotating block 18. The rotation of the rotating shaft 17 drives the bidirectional cam 20 to squeeze the T-shaped fixing column 14 and the fixing hole 13 to nest. When the rotating block 18 is rotated 90 degrees, the positioning pin 19 is inserted into the insertion hole opened on the surface of the rotating block 18, which is convenient for limiting and fixing the rotating block 18. The rotating block 18 fixes the rotating shaft 17, preventing the rotating shaft 17 from rotating again, and completing the installation of the injection mold 2.
