[0022] Please refer to Figures 1-4 The embodiments of the utility model include:

[0023] As shown in Figure 1 and Figure 2 The glass cover handle forming die comprises a die seat 1, a die core assembly 5, a top rod 3, a friction plate 6 and a connecting seat 2. The top of the die seat 1 is concave and provided with a downwardly extending conical groove 11. The top rod 3 is concentrically arranged in the conical groove 11. In the embodiment, a guide sleeve 4 corresponding to the top rod 3 is arranged in the die seat 1 to guide the lifting of the top rod 3. A stepped hole 12 below the guide sleeve 4 is arranged in the die seat 1. A driving rod 7 at the bottom of the top rod 3 is arranged in the stepped hole 12. The driving rod 7 can be connected with a driving mechanism to drive the lifting of the top rod 3.

[0024] In the embodiment, the die core assembly 5 comprises three die core blocks 51 arranged in an annular array outside the top rod 3. A sliding groove 13 corresponding to the die core block 51 is vertically arranged in the conical groove 11. A sliding block 8 connected with the back of the die core block 51 is arranged in the sliding groove 13 to guide the lifting of the die core block 51. The die core block 51 is radially displaced while being lifted along the inclined surface of the conical groove 11 to close and open the die.

[0025] As shown in Figure 4 The cross section of the sliding block 8 adopts a T-shaped structure to avoid disengaging from the sliding groove 13. A first screw 81 connected with the die core block 51 is arranged in the sliding block 8 for convenient assembly. As shown in Figure 3 The inner side of the die core block 51 is concave and provided with three handle forming cavities 52 respectively. The handle forming cavities 52 are used to form the handle after the die is closed.

[0026] A first inclined surface 53 below the handle forming cavity 52 is arranged on the inner side of the die core block 51. The first inclined surface 53 is inclined downwardly to the outer side of the die core block 51. A circular table 31 inside the first inclined surface 53 is arranged at the top of the top rod 3. The friction plate 6 is arranged on the side of the circular table 31 and in contact with the first inclined surface 53 one by one. The friction plate 6 is lifted and lowered with the top rod 3 to drive the lifting and opening and closing of the die core block 51 by cooperating with the first inclined surface 53. As shown in Figure 3 After the top rod 3 is lowered, the die core block 51 is lowered to close.

[0027] As Figure 4 The friction sheet 6 adopts a ring structure, can adopt stainless steel material, is polished clean, and is favorable for reducing the contact area and friction force with the first inclined surface 53. The friction sheet 6 is provided with a counterbore, the counterbore is provided with the second screw 61 connected with the circular truncated cone 31, and assembly is convenient. The second inclined surface 33 is arranged on the side surface of the circular truncated cone 31 and is attached with the friction sheet 6, so that the stability of the friction sheet 6 is ensured.
