At the same time, the bottom of the upper mold base 3 is closely attached to the top of the lower mold base 4 in a circle.

[0027] When the upper mold base 3 provided below the upper template 1 is pressed onto the upper part of the lower mold base 4, the upper mold core groove 301 and the lower mold core groove 401 provided inside it are combined, and injection liquid is injected into the combined part through the injection port 2, so that a product part 16 is formed inside.

[0028] Furthermore, a plurality of card slot parts 402 are opened in the lower mold core groove 401, and the top block 8 is clamped and slidably connected into the card slot parts 402. At the same time, the top of the top block 8 is flush with the bottom of the lower mold core groove 401. After the top of the top block 8, the inside of the lower mold core groove 401, and the inside of the upper mold core groove 301 are combined, a product part 16 is injection molded inside.

[0029] The top block 8 provided in the lower mold core groove 401 is placed below the product part 16. After the top block 8 encounters an external force, the product part 16 can be ejected from the lower mold core groove 401 during mold opening.

A plurality of limit posts 14 and a plurality of support posts 15 are respectively fixedly connected to the middle part of the lower template 6.

[0033] Further, a top plate assembly 7 is sleeved and slidably connected outside the limit posts 14 and the support posts 15, and there are gaps between the two sides of the top plate assembly 7 and the inner sides of the support blocks 5.

[0034] Further, the tops of the limit posts 14 are inserted and slidably connected into the bottom of the lower die base 4, and the tops of the support posts 15 are in close contact with the bottom of the lower die base 4.

[0035] The top plate assembly 7 provided between the lower die base 4 and the lower template 6 will move up and down along the limit posts 14 and the support posts 15 under the action of an external force.

[0036] Further, the bottoms of the top columns 11 are fixedly connected to the four corners of the top plate assembly 7, and the tops of the top columns 11 are inserted and slidably connected into the lower die base 4, and at the same time, the tops of the top columns 11 are in close contact with the bottom of the upper die base 3.

[0037] When the top columns 11 provided at the four corners of the top plate assembly 7 move up with the top plate assembly 7, the tops of the top columns 11 will push open the upper die base 3 and the structures above it.

[0038] Further, a plurality of first ejector rods 12 are fixedly connected inside the top plate assembly 7, and the tops of the first ejector rods 12 are inserted and slidably connected into the lower die base 4, and at the same time, the tops of the first ejector rods 12 are inserted and fixedly connected to the bottom of the top block 8.

[0042] Working principle:

[0043] Below the upper template 1, there is an upper die base 3. The injection port 2 provided inside the upper template 1 injects injection liquid into the upper die base 3 and injects it into the entire mold interior. The lower die base 4 is pressed below the upper die base 3. There is an upper die core groove 301 at the bottom of the upper die base 3. At the same time, there is a lower die core groove 401 above the lower die base 4. After the upper die core groove 301 and the lower die core groove 401 are combined, the product part 16 is formed after injection inside. Below the lower die base 4, there are support blocks 5 and a lower template 6. There are limit posts 14 and support posts 15 above the lower template 6. At the same time, a top plate assembly 7 is sleeved outside the limit posts 14 and the support posts 15. In this way, the top plate assembly 7 can move between the lower die base 4 and the lower template 6. On the top plate assembly 7, there are respectively a top post 11, a first ejector rod 12, and a second ejector rod 13. Since the top of the top post 11 is in contact with the bottom of the upper die base 3, after the first ejector rod 12 is inserted into the lower die base 4, it is connected to the ejector block 8 inside the lower die core groove 401. The top of the second ejector rod 13 also correspondingly abuts against the lower side of one side of the product part 16. When the mold is opened, under the action of an external force, the top plate assembly 7 moves the top post 11, the first ejector rod 12, and the second ejector rod 13 upward. Then the top post 11 first pushes open the upper die base 3 and the structures above it, so that the upper die base 3 is separated from the product part 16. Then the first ejector rod 12 pushes the ejector block 8 and the second ejector rod 13 together to eject the product part 16 from the lower die core groove 401, and the product part 16 is separated from the lower die base 4.
