A limit ring 704 is fixedly connected to the outer wall of one end of the mold 1 2, and the contact rod 703 is slidably inserted in the limit ring 704. A spring 705 is sleeved on the outside of the contact rod 703, and both ends of the spring 705 are fixedly connected to the limit ring 704 and one end of the contact rod 703 respectively. A limit plate 706 is provided on the outer wall of one end of the mold 2 4, which is opposite to the contact rod 703.

[0025] Start the hydraulic cylinder 3, which drives the mold 2 4 toward the mold 1 2. Then the contact rod 703 contacts the limit plate 706 on one side of the mold 2 4. At this time, the contact rod 703 will be squeezed to overcome the elastic force of the spring 705 and slide to one side. When the mold 2 4 and the mold 1 2 overlap, the contact rod 703 can drive one end of the ejector rod 701 to overlap with the inner wall of the mold 1 2 through the connecting plate 702, so that the ejector rod 701 will not affect the normal progress of the injection molding. After the work is completed, the mold 2 4 is driven back to its original position through the hydraulic cylinder 3. During this period, the contact rod 703 is no longer restricted. The spring 705 gradually drives the contact rod 703 back to its original position under the support of the limit ring 704. At the same time, the ejector rod 701 will move synchronously with the contact rod 703, and the workpiece attached to the mold will be ejected by the ejector rod 701.

Then the contact rod 703 contacts the limit plate 706 on one side of the mold 2 4. At this time, the contact rod 703 will be squeezed to overcome the elastic force of the spring 705 and slide to one side. When the mold 2 4 and the mold 1 2 overlap, the contact rod 703 can drive one end of the ejector rod 701 to overlap with the inner wall of the mold 1 2 through the connecting plate 702, so that the ejector rod 701 will not affect the normal progress of the injection molding. After the work is completed, the mold 2 4 is driven back to its original position through the hydraulic cylinder 3. During this period, the contact rod 703 is no longer restricted and the spring 705 Under the support of the limit ring 704, the contact rod 703 is gradually driven back to its original position, and the ejector rod 701 will move synchronously with the contact rod 703, and the workpiece attached to the mold will be ejected by the ejector rod 701. When the mold 2 4 is driven back to its original position, the pressing block 805 at one end thereof will contact the button 806, and the fan 803 will be powered on to start. The external air is drawn into the curved pipe 801, and then blown out from the nozzles 802 of the multiple curved pipes 801 at the top and bottom.
