[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-10 The mold, which allows for quick replacement of inserts, includes a rear template 1 (i.e., plate B), inserts 2, and a mold core 3. The mold core 3 is mounted on the rear template 1, and the inserts 2 are mounted on the mold core 3. It also includes a quick-release rod 4, which is rotatably mounted on the rear template 1 and the mold core 3. One end of the quick-release rod 4 is provided with a positioning post 5, and the insert 2 is provided with a positioning hole 6. A positioning engagement part and an actuating engagement part are provided between the positioning post 5 and the positioning hole 6. When the quick-release rod 4 rotates to the first position A and the positioning post 5 is inserted into the positioning hole 6, the positioning post 5 and the positioning hole 6 are positioned and engaged through the positioning engagement part, so that the insert 2 is fixed on the mold core 3. When the quick-release rod 4 rotates to the second position B and the positioning post 5 is inserted into the positioning hole 6, the quick-release rod 4 pushes the insert 2 upward through the actuating engagement part, so that part of the insert 2 extends out of the mold core 3.

[0028] When replacing insert 2, remove the fixing block 11, then pull the positioning pin 5 of the quick-release rod 4 out of the positioning hole 6 of insert 2, and then rotate the quick-release rod 4 180 degrees, that is, rotate the quick-release rod 4 to the second position B. Then reinsert the positioning pin 5 of the quick-release rod 4 into the positioning hole 6. At this time, the quick-release rod 4 pushes the insert 2 upward through the actuating mating part, so that part of the insert 2 extends out of the mold core 3. Then grasp the insert 2 by hand and pull the positioning pin 5 of the quick-release rod 4 out of the positioning hole 6 of insert 2. Then the insert 2 can be removed from the mold core 3. After the new insert 2 is installed into the mold core 3, the quick release rod 4 is rotated 180 degrees, that is, the quick release rod 4 is rotated to the first position A. Then the positioning pin 5 of the quick release rod 4 is inserted into the positioning hole 6. At this time, the positioning pin 5 and the positioning hole 6 are positioned and engaged through the positioning mating part, so that the insert 2 is fixed on the mold core 3. Then the fixing block 11 is reinstalled to lock the quick release rod 4. At this time, the quick release rod 4 cannot be rotated or moved, thus completing the replacement of the insert 2. Figure 9 andFigure 10 For different inserts 2.

[0029] The positioning and mating part includes a positioning inclined surface 8 on one side of the positioning post 5 and a mating inclined surface 9 on one side of the positioning hole 6. A positioning and mating inclined surface 7 is provided on the other side of the positioning hole 6. When the quick release lever 4 is rotated to the first position A and the positioning post 5 is inserted into the positioning hole 6, the positioning inclined surface 8 and the mating inclined surface 9 are in contact with each other, and the actuating inclined surface 10 is in contact with the positioning and mating inclined surface 7, so that the positioning post 5 and the positioning hole 6 are positioned and mated.

[0030] The actuation mating part includes an actuation inclined surface 10 disposed on the other side of the positioning post 5 and a mating inclined surface 9 disposed on one side of the positioning hole 6; when the quick release rod 4 rotates to the second position B and the positioning post 5 is inserted into the positioning hole 6, the quick release rod 4 lifts the insert 2 through the mating of the actuation inclined surface 10 and the mating inclined surface 9; the taper of the positioning inclined surface 8 is different from that of the actuation inclined surface 10.

[0031] The actuating inclined surface 10 is positioned closer to the outer side of the positioning post 5 than the positioning inclined surface 8, so that when the quick release lever 4 rotates to the first position A, the positioning inclined surface 8 and the mating inclined surface 9 can fit together, and the actuating inclined surface 10 and the positioning mating inclined surface 7 can fit together. When the quick release lever 4 rotates to the second position B, the quick release lever 4 can lift the insert 2 through the engagement of the actuating inclined surface 10 and the mating inclined surface 9.

[0032] It also includes a fixing block 11, which is detachably fixed to the rear template 1. The other end of the quick-release rod 4 is detachably connected to the fixing block 11, so that when the fixing block 11 is fixed to the rear template 1, the quick-release rod 4 can be locked to prevent it from loosening.

[0033] The fixing block 11 is provided with a first fixing hole 19, and the rear template 1 is provided with a second fixing hole 20. The first fastener (screw) passes through the first fixing hole 19 and is fastened to the second fixing hole 20, thereby fixing the fixing block 11 to the rear template 1.

[0034] The fixing block 11 is provided with a third fixing hole 21, and the other end of the quick release rod 4 is provided with a fourth fixing hole 22. The second fastener 23 (screw) passes through the third fixing hole 21 and is fastened to the fourth fixing hole 22, thereby connecting the quick release rod 4 and the fixing block 11.

[0035] The other end of the quick-release lever 4 is provided with a plug 12, and the fixing block 11 is provided with a socket 13. The plug 12 is positioned and inserted into the socket 13. The plug 12 and the socket 13 are non-circular.

[0036] It also includes a pressure block 14, which is detachably fixed to the rear template 1 and is located inside the fixing block 11. The pressure block 14 is provided with a through hole 15, and the other end of the quick release rod 4 passes through the through hole 15, which can be used to position the quick release rod 4 up and down.

[0037] The pressure block 14 is provided with a fifth fixing hole 24, and the rear template 1 is provided with a sixth fixing hole 25. The third fastener (screw) passes through the fifth fixing hole 24 and is fastened to the sixth fixing hole 25 so that the pressure block 14 is fixed on the rear template 1.

[0038] The mold core 3 is provided with a mounting groove 16. The insert 2 is positioned and installed in the mounting groove 16. When the quick release rod 4 pushes the insert 2 upward through the actuation mating part, the upper end of the insert 2 extends out of the mounting groove 16. At this time, the insert 2 can be grasped by hand and then removed from the mounting groove 16.

[0039] The rear template 1 is provided with an installation groove 17, and the mold core 3 is provided with an installation hole 18. The installation hole 18 is connected to the installation slot 16. The quick release rod 4 passes through the installation groove 17 and the installation hole 18 in sequence and is inserted into the installation slot 16, so that the quick release rod 4 can rotate on the rear template 1 and the mold core 3, and at the same time, the positioning pin 5 can be inserted into the positioning hole 6.
