[0028] Template 1, a top sleeve 2 is installed between the inner walls of template 1, a lower push plate 3 is provided at the top of the top sleeve 2, and an upper push plate 4 is provided at the top of the lower push plate 3; and

[0029] The secondary ejection assembly 5 includes multiple U-shaped blocks 501, each U-shaped block 501 is fixedly installed on the outer wall of the template 1, and multiple mounting slots are opened on the outer wall of the push plate 3. A mounting seat 502 is fixedly installed on the inner wall of each mounting slot. A rotating shaft 503 is embedded through the outer wall of each mounting seat 502. A bend 504 is rotatably sleeved on the outer surface of each rotating shaft 503. A drive shaft 505 and a driven shaft 506 are rotatably embedded between the outer walls of each bend 504. A drive wheel 507 and a driven wheel 508 are fixedly sleeved on the outer surface of each drive shaft 505 and driven shaft 506, respectively.

[0030] In this embodiment, the upper push plate 4 and the lower push plate 3 are movably sleeved between the outer surfaces of multiple positioning columns on the template 1. The upper push plate 3 and the upper push plate 4 can be easily moved by the top sleeve 2. After the lower push plate 4 moves a certain distance, the drive wheel 507 on the elbow 504 inside its mounting groove will abut against the inner wall of the U-shaped stop 501, thereby driving the elbow 504 to rotate on the surface of the rotating shaft 503 on the mounting base 502. This will then drive the driven shaft 506 and its surface driven wheel 508 to abut against the bottom of the upper push plate 4, achieving secondary ejection and demolding. The action is reliable and the structure is simple.

[0031] Please refer to the specific details. Figure 1 As shown, each U-shaped stop 501 is detachably installed on the outer wall of the template 1 by bolts.

[0032] In this embodiment, the U-shaped stop 501 is installed with bolts, which facilitates the installation, disassembly, and maintenance of the U-shaped stop 501, thereby improving its service life.

[0033] Please refer to the specific details. Figure 3 As shown, a wear-resistant plate 6 is fixedly connected to one side of the outer wall of each U-shaped stop 501.

[0034] In this embodiment, a wear-resistant plate 6 is provided on the outer wall of the U-shaped stop 501. This wear-resistant plate 6 corresponds to the corresponding drive wheel 507, which avoids damage to the U-shaped stop 501 caused by the drive shaft 505 and the drive wheel 507, and improves its service life.

[0035] Please refer to the specific details. Figures 1-3As shown, multiple wear-resistant plates 6 are also fixedly connected to the bottom of the upper push plate 4, and each wear-resistant plate 6 is located inside the corresponding mounting groove.

[0036] In this embodiment, a wear-resistant plate 6 is provided at the bottom of the upper push plate 4. This wear-resistant plate 6 corresponds to the driven wheel 508, so as to avoid damage to the upper push plate 4 by the driven shaft 506 and the driven wheel 508.

[0037] Please refer to the specific details. Figures 1-3 As shown, each mounting base 502 is detachably mounted to the inner wall of the corresponding mounting slot by bolts.

[0038] In this embodiment, the mounting base 502 is fixed by bolts, which improves the ease of installation and disassembly of the mounting base 502.

[0039] Please refer to the specific details. Figures 1-3 As shown, the bending angle of each elbow 504 is greater than 90°.

[0040] In this embodiment, the bending angle of each elbow 504 is greater than 90°, which makes it easy for the drive wheel 507 on the elbow 504 to contact the U-shaped stop 501, and facilitates the use of the secondary ejection assembly 5.

[0041] Working principle: During demolding, the injection molding machine moves the lower push plate 3 by pushing it with the top sleeve 2 on the template 1. At this time, the upper push plate 4 moves with the lower push plate 3. Simultaneously, the mounting base 502 and the elbow 504 mounted on it move to complete the first demolding action. When the drive wheel 507 abuts against the wear-resistant plate 6 on the U-shaped stop 501, it continues to push out. The elbow 504 is pressed and rotates with the rotating shaft 503 on the mounting base 502, driving the driven wheel 508 to push upward. At this time, the driven wheel 508 abuts against the wear-resistant plate 6 at the bottom of the upper push plate 4 and pushes the upper push plate 4 to move continuously, thereby completing the second demolding action.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
