[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] An automatic demoulding mold with an ejection structure, such as Figure 1-Figure 7 As shown, it includes a support seat 1, a lower die seat 2, a lower module 3, a positioning column 4, an upper die seat 5, a punch 6, a mounting rod 7, a top block 10, a guide rod 11, a reset spring 12 and a clamping block 13. The support seat 1 is provided with a lower die seat 2, and the lower die seat 2 is provided with a lower module 3, and the lower module 3 can be replaced as needed. A plurality of positioning columns 4 are installed on the lower die seat 2, and the plurality of positioning columns 4 slide through the upper die seat 5 together. A punch 6 is installed at the bottom of the upper die seat 5, and the punch 6 movably enters the lower module 3 and can be replaced. A top block 10 is arranged in the lower die seat 2, and the top block 10 slides into the lower module 3. A guide rod 11 is symmetrically installed at the bottom of the top block 10, and a reset spring 12 is sleeved on the outer side of the guide rod 11. Both ends of the guide rod 11 are slidably connected with clamping blocks 13, and mounting rods 7 are symmetrically installed on both sides of the upper die seat 5. The clamping block 13 is in movably contact with the mounting rod 7, and the bottom of the mounting rod 7 is an inverted trapezoidal structure.

[0024] Place the material on the lower module 3, push the upper die seat 5 downward along the positioning column 4, the upper die seat 5 moves downward with the punch 6, the punch 6 squeezes the material downward, and squeezes the material into the lower module 3 for molding. After the molding work is completed, the upper die seat 5 moves upward with the punch 6, and the mounting rods 7 on both sides move upward. The mounting rods 7 squeeze the card block 13 inward, and the card block 13 moves inward and upward with the mounting rods 7. The card block 13 pushes the top block 10 upward, and the top block 10 slides into the lower module 3, moves upward and lifts up the molded product. After taking out the product, the next round of film pressing can be carried out.

[0025] Example 2

[0026] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a sliding rod 8, an elastic member 9 and a baffle 14. A plurality of sliding rods 8 are slidably arranged in the cavity in the support seat 1 and the lower die seat 2. The outer sides of the sliding rods 8 are sleeved with elastic members 9. The top block 10 is in movably contact with the sliding rod 8. The top block 10 movably squeezes the sliding rod 8. Baffles 14 are installed on both sides of the lower die block 3 to prevent material deviation.

[0027] When the upper die seat 5 moves downward, the clamping block 13 loses its supporting force and moves downward under the gravity of the top block 10. At the same time, it moves to both sides under the restoring elastic force of the restoring spring 12. As the top block 10 leaves the lower die block 3, the top block 10 moves downward and contacts the sliding rod 8. The sliding rod 8 supports the top block 10 and plays a supporting role.
