[0022] Through the above technical solution, when the device is in use, the mold product is completed in the cavity of the mold body 1, the limit on the inner insert rod 2 is released by pushing the limit mechanism, and the adapter seat 5 can be lifted up by cooperating with the rebound lifting mechanism, thereby assisting in removing the product from the mold body 1.
[0023] Specifically, the push-and-limit mechanism includes a fixing platform 6 fixedly connected to the outer surface of the mold body 1 , and a platform shaft 7 is fixedly penetrated through the inner side of the fixing platform 6 .
[0024] Through the above technical solution, turning the handle 9 can make the rotating frame 8 rotate along the table axis 7, so as to change the position of the swing piece 11 through the first sheet axis 10.
[0025] Specifically, the outer surface of the table shaft 7 is rotatably connected to a rotating frame 8 , and the top of the rotating frame 8 is fixedly connected to a handle 9 .
[0026] Through the above technical solution, a groove is provided on the lower surface of the rotating frame 8 to facilitate the push and pull of the limiting iron rod 13 by the swing piece 11 during the deflection process.
[0027] Specifically, the inner surface of the rotating frame 8 is rotatably connected to the first shaft 10 , and the outer surface of the first shaft 10 is rotatably connected to the swing piece 11 .
[0028] Through the above technical solution, the swing plate 11 can push the limiting iron rod 13 through the second plate shaft 12 during the swinging process, thereby pushing it into the limiting groove 3.
[0029] Specifically, one end of the swing piece 11 away from the first shaft 10 is rotatably connected to the second shaft 12, the outer surface of the second shaft 12 is rotatably connected to the limiting iron rod 13, and the outer surface of the limiting iron rod 13 is slidably connected to the inner surface of the fixed platform 6.
[0030] Through the above technical solution, the groove formed at the end of the limiting iron rod 13 facilitates the smooth deflection of the swing piece 11, and the limiting iron rod 13 is extended and retracted through the fixing platform 6 through the deflection.
[0031] Specifically, the rebound lifting mechanism includes a rotating shaft 14 fixedly connected to the inside of the mold body 1, and the outer surface of the rotating shaft 14 is rotatably connected to the upper ejector rod 15. A spring 16 is arranged inside the mold body 1, and the top of the spring 16 is fixedly connected to the lower surface of the upper ejector rod 15.
[0032] Through the above technical solution, two groups of springs 16 are respectively arranged under the two groups of upper push rods 15 , and the adapter seat 5 can be lifted up by the upper push rods 15 in cooperation with the cut surface arranged at the top of the upper push rods 15 .
[0033] Working principle: When the device is in use, before the mold product is made in the cavity of the mold body 1, the inner rod 2 is inserted into the mold body 1 until the adapter seat 5 is completely in the bottom wall of the cavity inside the mold body 1. During this process, the adapter seat 5 will press down the upper push rod 15 and compress the spring 16. At this time, the two groups of limiting grooves 3 on the outer surface of the inner rod 2 are facing the two groups of limiting iron rods 13. The handle 9 is pushed from the outside to make the rotating frame 8 rotate along the table axis 7, thereby changing the position of the first sheet axis 10 and making the swing piece 11 rotate along the first sheet axis 10. During this process, the swing piece 11 will rotate along the second sheet axis 12, and push the limiting iron rod 13 through the second sheet axis 12, so that the limiting iron rod 13 passes through the fixed table 6 and gradually approaches the inner rod. Rod 2, until the two sets of limiting iron rods 13 are completely inserted into the limiting grooves 3, and cooperate with the magnetic sheet 4 to make the limiting iron rods 13 stable in the limiting grooves 3, the inner inserted rod 2 can be limited and fixed, and the product can be completed in the inner cavity of the mold body 1. After the production is completed, the product and the inner wall of the cavity of the mold body 1 will have a large adhesion. At this time, the handle 9 can be pulled outward to pull the limiting iron rod 13 back through the swing piece 11 until the limiting iron rod 13 no longer restricts the inner inserted rod 2. At this time, the upper push rod 15 can be lifted under the elastic reset action of the spring 16 and rotated along the rotating shaft 14, thereby pushing the adapter 5 upward, applying force to the product from the inside of the mold body 1, and facilitating the product to be taken out from the inner cavity of the mold body 1.
