DETAILED DESCRIPTION

[0016] See also Figure 1-3The present embodiment is a smart lamp post dovetail groove forming mold, including an upper mold and a lower mold, the upper mold including an upper mold base 7, the upper mold base 7 is provided with a mold cavity at the bottom, two guide bevel blocks 8 are symmetrically arranged on both sides of the mold cavity, the opening between the two guide bevel blocks 8 gradually expands from top to bottom, an upper module 9 is arranged on the inner side of each of the two guide bevel blocks 8, and the upper module 9 is slidably connected with the corresponding guide bevel block 8, the upper mold base 7 is provided with a waist-shaped hole 12 corresponding to the two upper modules 9, and a connecting rod 3 is arranged in the waist-shaped hole 12, The connecting rod 3 passes through the waist-shaped hole 12 and is fixedly connected to the corresponding upper module 9, and a return spring 13 is installed between the upper module 9 and the upper mold base 7; a sliding pad 5 is installed above the two guide bevel blocks 8 in the mold cavity, and a through hole is provided on both sides of the upper mold base 7 corresponding to the two sliding pads 5, and a connecting screw 6 is installed in the through hole, and the inner end of the connecting screw 6 is fixedly connected to the pad; an upper top block 4 is provided in the middle of the top of the mold cavity, and the lower mold includes a lower mold base 11, and a lower top block 10 is installed on the top of the lower mold base 11.

[0017] Furthermore, the connecting rod 3 is a screw, and a nut is provided at the outer end of the screw, and the size of the nut is larger than the waist-shaped hole 12.

[0018] Furthermore, the guide bevel block 8 is fixedly connected to the inner wall of the mold cavity, and a guide bevel is provided on the side of the guide bevel block 8 facing the upper module 9. A slide groove is provided on the guide bevel along the length direction of the bevel, and a slider is installed in the slide groove. The slider is connected to the corresponding upper module 9 by bolts.

[0019] Furthermore, a die tip portion for forming a dovetail groove is provided at the bottom of the upper die block 9 on one side facing the center line.

[0020] Furthermore, an upper die handle 2 is provided at the top of the upper die base 7 , and the top of the upper die handle 2 is detachably connected to the bending machine slider 1 .

[0021] The working principle of the utility model is as follows: before pressing, the upper die block 9 moves downward along the guide bevel block 8 under the push of the return spring 13 to form a cavity at the upper end of the die cavity in the upper die base 7, and the sliding pad 5 is manually or other mechanically controlled to be inserted into the cavity to support the upper die block 9, so that the upper die block 9 cannot move upward.

[0022] Driven by the slider 1 of the bending machine, the upper die block 9, together with the sliding pad 5, the upper die seat 7 and the die handle 2, is pressed down together, and the sheet metal becomes convex between the upper die block 9 and the lower top block 10, as shown in FIG. Figure 4 As shown; Then the sliding pad 5 is pulled to both sides manually or mechanically controlled to leave space in the cavity at the upper end of the die cavity. At this time, the bending machine slider 1 continues to move downward, and the two upper modules 9 move toward the center and upward under the guidance of the guide bevel block 8. The die tips of the two upper modules 9 push the lower end of the side wall of the convex workpiece and squeeze and shrink toward the middle, thereby completing the formation of the dovetail groove, as shown in FIG. Figure 5 shown.

[0023] After the dovetail groove is formed, the upper die block 9 moves downward along the guide bevel block 8 and opens to form an escape space under the push of the return spring 13, so that the dovetail groove workpiece can be taken out therefrom, thereby completing the demoulding of the dovetail groove workpiece.
