[0017] S4: The motor drives the driving shaft to rotate, and pushes the sleeve ring and the circular plate to move, so that the arc-shaped push plate drives the demolding module to move to the right to demold the solidified product.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, the circular plate will push the push rod to move to the right side when it moves to the right side. When the push rod moves to the right side, it will push the push plate to move, and the push plate will drive the telescopic plate to move to the right side together. When the telescopic plate moves to the right, it will drive the arc moving plate to move to the right side. When the arc moving plate moves to the right, it will drive the rotating rod to rotate. When the rotating rod rotates, it will pull the arc moving plate to move inward, so that the molded material and the surface of the arc moving plate are separated from each other, avoiding the situation that after injection molding, the plastic parts are not completely cooled and fixed due to the pursuit of efficiency during demolding, and part of the injection molded parts may remain in the mold cavity, so that the plastic products stick to the mold and cannot be demolded smoothly.

[0020] (2) In the present invention, when the arc-shaped movable plate drives the rotating rod to rotate, the rotating rod will squeeze the sliding block during the rotation process, and the sliding block squeezes the extrusion rod to move it inward. When the sliding block squeezes the extrusion rod to move inward, the sliding block will also slide inside the slideway of the side wall of the rotating rod. When the extrusion rod moves inward, it will drive the extrusion plate to move inward together, thereby squeezing the airbag. When the gas inside the airbag is squeezed, it will enter the interior of the arc-shaped movable plate through the air supply pipe, and finally be discharged through the air outlet on one side of the arc-shaped movable plate. The airflow generated by the air blowing mechanism can generate negative pressure or pressure difference to a certain extent, which helps to separate the product from the mold, and can remove residues between the mold and the product during the blowing process, thereby improving the quality of the product.

[0021] (3) In the present invention, when the electric push rod pushes the moving block to move to the left, it will also drive the opening and closing block to move to the opposite side while moving to the left. When the opening and closing block moves, the semicircular groove inside it will contact with the top plate. When the top plate contacts with the semicircular groove, along with the movement of the opening and closing block, it will push the top plate to move to the left. When the top plate moves to the left, it will support the arc-shaped movable plate to move to the left together, and drive the fixed column to move. When the fixed column moves, the arc groove on the side of the sealing plate close to the arc-shaped movable plate will push the sealing plate to move to both sides when the fixed column moves to the left, thereby sealing the air outlet on the outer surface of the arc-shaped movable plate to prevent the injection material from entering the interior of the arc-shaped movable plate through the air outlet during injection molding, thereby damaging the equipment. When the injection material enters the interior of the arc-shaped movable plate through the air outlet, the molded finished product will also be stuck during demolding, thereby making it difficult to demold.

[0022] (4) In the present invention, when the arc-shaped push plate pushes the demolding module to move to the right, the rectangular limit block will hold the telescopic block to keep it stationary. Along with the movement of the demolding module, the telescopic block will pull the connecting plate to drive the rotating block to rotate. The rotating block will cause another connecting plate to rotate during the rotation. When the connecting plate rotates, it will drive the sliding column to move to the right, and drive the support plate to move to the right through the connecting block, so that the support plate supports the inner wall of the finished product, thereby reducing the uneven force on the mold during the demolding process, reducing the wear and damage of the mold, and thus extending the service life of the mold.

When the opening and closing block 705 moves to the left, it will pass through the slide groove on the top of the base 1, which will cause the opening and closing block 705 to move to the opposite side during the movement to the left, and finally close each other. The material for injection molding is injected into the opening and closing block 705 through the injection head 704. The liquid material will pass through the injection hole and finally enter the semicircular groove, so that the liquid material fills the semicircular groove and then cools and solidifies the liquid material through the cooling system. When the material solidifies, start the electric push rod 705. 02 drives the moving block 703 to move to the right, and drives the opening and closing block 705 through the moving block 703 to open when it moves to the right, and starts the motor 201. During the operation, the motor 201 drives the driving shaft 202 to rotate. When the driving shaft 202 rotates, it drives the collar 203 to move to the right, and drives the circular plate 204 to move to the right together. When the circular plate 204 moves to the right, it pushes the stripping module 206 to move to the right together through the arc-shaped push plate 205. When the circular plate 204 moves to the right, it also pushes the ejector rod 301 to move to the right. When the ejector rod 301 moves to the right, it pushes the push plate 302 to move. The push plate 302 drives the telescopic plate 304 to move to the right side. When the telescopic plate 304 moves to the right, it drives the arc moving plate 305 to move to the right side. When the arc moving plate 305 moves to the right, it drives the rotating rod 306 to rotate. When the rotating rod 306 rotates, it pulls the arc moving plate 305 to move inward, so that the formed material is separated from the surface of the arc moving plate 305. When the arc moving plate 305 drives the rotating rod 306 to rotate, the rotating rod 306 squeezes the sliding block 401 during the rotation process, and squeezes the extruding rod 402 through the sliding block 401 to move it inward, and the sliding block 401 squeezes the extruding rod 402 inwardly. During the process, the sliding block 401 will also slide inside the slideway of the side wall of the rotating rod 306. When the squeezing rod 402 moves inward, it will drive the squeezing plate 403 to move inward together, thereby squeezing the airbag 404. When the gas inside the airbag 404 is squeezed, it will enter the interior of the arc-shaped moving plate 305 through the air pipe 405, and finally be discharged through the air outlet on one side of the arc-shaped moving plate 305. When the electric push rod 702 pushes the moving block 703 to move to the left, it will also drive the opening and closing block 705 to move to the opposite side while moving to the left. When the opening and closing block 705 moves, the semicircular groove inside it will contact with the top plate 503. When the top plate 503 contacts with the semicircular groove,As the opening and closing block 705 moves, the top plate 503 is pushed to move to the left. When the top plate 503 moves to the left, it will support the arc-shaped movable plate 502 to move to the left together, and drive the fixed column 504 to move. When the fixed column 504 moves, the arc-shaped groove on the side of the sealing plate 505 close to the arc-shaped movable plate 502 will push the sealing plate 505 to move to both sides when the fixed column 504 wants to move to the left, thereby sealing the air outlet on the outer surface of the arc-shaped movable plate 305. The arc-shaped push plate 205 pushes the stripping module 206 to move to the right. When the rectangular limit block 208 holds the telescopic block 603 still, the telescopic block 603 pulls the connecting plate 602 to drive the rotating block 601 to rotate, and the rotating block 601 rotates the other connecting plate 602, and the connecting plate 602 drives the sliding column 604 to move to the right, and drives the supporting plate 605 to move to the right through the connecting block, so that the supporting plate 605 holds the inner wall of the finished product, and the rightward movement of the stripping module 206 pushes the product to move to the right, and finally falls off.
