[0024] The right side of the fixed column 21 is fixedly connected to the left side of the lower die seat 3. A square groove 22 is provided on the inner side of the fixed column 21. The lower die seat 3 will compress the spring 1 29 by pushing the support rod 27, and the lower die seat 3 will directly compress the spring 210. When the lower die seat 3 moves downward, the clamping rod 26 will slide relatively along the square groove 22. A fan-shaped groove 23 is provided at the top of the square groove 22. A connecting groove 222 is provided on the inner side of the protective shell 1. The fixed column 21 passes through the connecting groove 222 and is slidably connected. First, the upper The mold base 4 and the protective shell 1 are fixed to the mold production equipment. The upper mold base 4 is pushed by the cylinder in the mold production equipment to close the upper mold base 4 and the lower mold base 3, and the lower mold base 3 is pushed to enter the protective shell 1. The top surface of the support rod 27 is fixedly connected to the bottom surface of the lower mold base 3. The support rod 27 passes through and is slidably connected with a positioning column 28. The bottom surface of the positioning column 28 is fixedly connected to the inner side of the protective shell 1. The bottom surface of the support rod 27 and the inner side of the positioning column 28 are fixedly connected with a spring 29. The lower mold base 3 and the protective shell 1 are fixedly connected. The inner side of the protective shell 1 is fixedly connected with a spring 210. After the injection molding is completed and cooled, the upper mold base 4 is raised. After the upper mold base 4 is raised for a certain distance, the clamping rod 26 is still stuck in the fan-shaped groove 23, and the spring 1 29 and the spring 210 will not lift the lower mold base 3, so that a certain gap is generated between the upper mold base 4 and the lower mold base 3, thereby releasing the airtightness between the upper mold base 4 and the lower mold base 3 when they are closed. The bottom surface of the impact plate 24 is fixedly connected to the top surface of the protective shell 1, and the inside of the impact plate 24 penetrates and rotates A rotating rod 25 is connected, and a clamping rod 26 is fixedly connected to the surface of the bottom end of the rotating rod 25. When the lower mold base 3 is completely embedded in the protective shell 1, the position of the clamping rod 26 is just flush with the fan-shaped groove 23. The rotating rod 25 is driven by the spiral spring 211 to rotate into the fan-shaped groove 23, so that the clamping rod 26 limits the fixed column 21, thereby preventing the lower mold base 3 from being bounced up.

The inner side of the impact plate 24 is provided with a toggle groove 212 and a slide groove 215. When the upper die seat 4 is continuously raised, the edge of the upper die seat 4 will first contact the inclined surface of the contact block 214, causing the contact block 214 to pass through the push rod 216, and the push rod 216 will contact the moving groove 219 through the insertion rod 221 and the moving block 220, and at the same time, it will push the toggle rod 213, and the moving block 220 will slide along the moving groove 219 to prevent the toggle rod 213 from getting stuck. The surface of the top of the rotating rod 25 is fixedly connected with the toggle rod 213. When the toggle rod 213 rotates, it will drive the rotating rod 25 to rotate. After the rotating rod 25 rotates, it will drive the clamping rod 26 to rotate back into the square groove 22 and no longer conflict with the fan-shaped groove 23.

The lower mold base 3 will compress the spring 1 29 by pushing the support rod 27, and the lower mold base 3 will directly compress the spring 2 210. When the lower mold base 3 moves downward, the clamping rod 26 will slide relatively along the square groove 22. When the lower mold base 3 is completely embedded in the protective shell 1, the position of the clamping rod 26 is just flush with the fan-shaped groove 23. The spiral spring 211 drives the rotating rod 25 to rotate and enter the fan-shaped groove 23, so that the clamping rod 26 limits the fixed column 21, so that the lower mold base 3 cannot be bounced up, thereby preventing the lower mold base 3 and the protective shell 1 from loosening due to equipment vibration during the injection molding process.
[0026] After the injection molding is completed and cooled, the upper mold base 4 is raised. After the upper mold base 4 is raised for a distance, the clamping rod 26 is still stuck in the fan-shaped groove 23, and the spring 1 29 and the spring 210 will not lift the lower mold base 3, so that a certain gap is generated between the upper mold base 4 and the lower mold base 3, thereby releasing the airtightness between the upper mold base 4 and the lower mold base 3 when closed, allowing air to enter the lower mold base 3. At this time, the upper mold base 4 continues to be raised, and the edge of the upper mold base 4 will first contact the inclined surface of the contact block 214, causing the contact block 214 to pass through the push rod 216, and the push rod 216 will contact the moving groove 219 through the insert rod 221 and the moving block 220, and at the same time, it will push the toggle rod 213, and the moving block 220 slides along the moving groove 219 to prevent the toggle rod 213 from getting stuck. The angle between 16 and the toggle rod 213 is reduced, and the toggle rod 213 is effectively pushed to rotate. When the toggle rod 213 rotates, it will drive the rotating rod 25 to rotate, and after the rotation, the rotating rod 25 will drive the clamping rod 26 to rotate back into the square groove 22 and no longer conflict with the fan-shaped groove 23. At this time, the compressed spring 1 29 and the spring 2 210 will instantly lift the lower mold base 3, and when the lower mold base 3 is lifted up, the fixed column 21 will be lifted up together, and when the fixed column 21 rises, it will hit the bottom surface of the impact plate 24, so that the lower mold base 3 will vibrate violently, and the internal injection molding mold will loosen due to the strong inertia caused by the fixed column 21 hitting the impact plate 24, so that the internal mold is easier to take out, without the need for manual lifting, to prevent damage to the mold edge.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
