The outer wall of the control block 92 at the right end of the filling rod 8 is slidably connected with a starting rod 93. The left end of the starting rod 93 is provided with a groove that matches the shape of the control block 92. The inner wall of the starting rod 93 is elastically connected to the right end of the control block 92 through a spring 94. One end of the spring 94 is fixedly connected to the inner wall of the starting rod 93, and the other end of the spring 94 is fixedly connected to the right end of the control block 92.

[0035] Reference Figure 2 - Figure 4 The outer wall of the starting rod 93 is rotatably connected with a connecting plate 95, the top of the connecting plate 95 is fixedly connected to the bottom end of the bracket 2, the outer wall of the starting rod 93 and the inner wall of the connecting plate 95 are elastically connected through a torsion spring 98, one end of the torsion spring 98 is fixedly connected to the outer wall of the starting rod 93, and the other end of the torsion spring 98 is fixedly connected to the inner wall of the connecting plate 95, the number of turns of the torsion spring 98 is greater than the number of turns of the external thread of the filling rod 8, and the outer wall of the starting rod 93 is fixedly connected with a pull rope 96, and the pull rope 96 has no elastic In the initial state, the pull rope 96 is wound around the outer wall of the starting rod 93, and the number of turns of the pull rope 96 wound around the outer wall of the starting rod 93 is slightly less than the number of external thread turns on the outer wall of the filling rod 8. By setting the number of turns, it is ensured that the filling rod 8 will not be separated from the fixed plate 5. The end of the pull rope 96 away from the starting rod 93 is fixedly connected to a pulling block 97, and the left end of the pulling block 97 is fixedly connected to the right end of the movable plate 4. By setting the pulling block 97, it is ensured that the pull rope 96 can be pulled when demoulding.

[0036] Reference Figure 4 - Figure 6A material taking component 10 is arranged inside the fixed mold 7, and the material taking component 10 includes a mounting groove 101, which is opened on the inner wall of the fixed mold 7, and the mounting groove 101 is arranged on the outer side of the area where the filling rod 8 is located. A push block 102 is slidably connected to the inner wall of the mounting groove 101, and the right end of the push block 102 is elastically connected to the inner wall of the mounting groove 101 by a second spring 103, one end of the second spring 103 is fixedly connected to the right end of the push block 102, and the other end of the second spring 103 is fixedly connected to the inner wall of the mounting groove 101, and a reset block 104 is slidably connected to the inner wall of the fixed mold 7, and a convex block approximately in a right-angled trapezoid is arranged at one end of the reset block 104 close to the filling rod 8, and the left view shape of the push block 102 is a rectangular parallelepiped with a fan-shaped shape, and a reset groove 105 is opened at one end of the push block 102 close to the reset block 104, and the reset groove 105 is arranged to ensure that the reset block 104 can drive the push block 102 to reset.

[0037] Working principle: During use, when demoulding, the cylinder 3 drives the movable plate 4 to move to the left, so that the movable plate 4 drives the movable mold 11 to move to the left. In the process of the movable plate 4 moving to the left, it drives the pulling block 97 to move to the left, so that the pull rope 96 is pulled.

[0038] After the pull rope 96 is pulled, the pull rope 96 drives the start rod 93 to rotate, so that the start rod 93 drives the control block 92 to rotate. Since the control block 92 is inside the control groove 91, the control block 92 drives the filling rod 8 to rotate.

[0039] During the rotation of the filling rod 8, the filling rod 8 will move toward the control block 92. Since the control block 92 can slide in the groove opened at the left end of the starting rod 93, the rotation of the filling rod 8 driven by the starting rod 93 will not be affected during the movement.

[0040] When the filling rod 8 moves away from the area where the reset block 104 is located, the reset groove 105 moves toward the direction close to the finished product under the drive of the second spring 103, and pushes the finished product to facilitate demoulding of the finished product.

[0041] When the equipment is used again, the cylinder 3 drives the movable plate 4 to move to the right. At this time, the pull rope 96 is not subjected to tension, so the starting rod 93 is reset under the torsion of the torsion spring 98, and the control block 92 is driven to rotate through the starting rod 93, and the filling rod 8 is driven to rotate through the control block 92.

[0042] During the rotation of the filling rod 8, the filling rod 8 will move toward the left end. Since the control block 92 is subjected to the leftward force of the spring 1 94, the control block 92 can maintain its position inside the control groove 91 unchanged, thereby ensuring that the control block 92 can always drive the filling rod 8 to rotate.

[0043] After rotating to a suitable position, the filling rod 8 squeezes the reset block 104 so that the reset block 104 enters the reset groove 105, thereby the reset block 104 squeezes the inclined surface of the reset groove 105 to drive the push block 102 to move rightward, so that the push block 102 does not affect the injection molding effect during use.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
