[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 3 This application provides a lever mechanism 10 for separating the mother template 40 and the upper fixing plate 20 (in... Figure 6 As shown in the diagram, the lever mechanism 10 includes a first lever 100, a second lever 110, a latching mechanism 120, and a limiting portion 70. The first lever 100 is configured to be fixed to the upper fixing plate 20 and includes a protrusion 101. The protrusion 101 is configured to protrude towards the mother template 40. The second lever 110 includes a first end 111 and a second end 112 disposed opposite to each other. The first end 111 is configured to be movably inserted into the mother template 40, and the second end 112 is detachably connected to the protrusion 101. The latching mechanism 120 is disposed on the protrusion 101. The protrusion 101 is configured to elastically abut against the second end 112 by the latching mechanism 120. The limiting portion 70 is disposed on the first end 111. The limiting part 70 is configured to limit the second lever 110 on the mother template 40, reducing the risk of the second lever 110 detaching from the mother template 40, so as to separate the first lever 100 from the second lever 110.

[0028] This application configures the lever mechanism 10 as a detachably connected first lever 100 and second lever 110, so that the lever mechanism 10 does not interfere with the robot arm's grasping and removal of the material head when the mother mold 40 and the upper fixed plate 20 are separated. The detachable connection between the protrusion 101 of the first lever 100 and the second lever 110 ensures ease of separation of the mother mold 40 and the upper fixed plate 20, while not affecting the smooth operation of the robot arm. The design of the snap-fit ​​mechanism 120 ensures that the protrusion 101 can be firmly connected to the second end 112 before the mother mold 40 is separated from the upper fixed plate 20, enhancing the stability of the entire lever mechanism 10. By setting the limiting part 70, the second lever 110 can be limited to the mother mold 40 when the mother mold 40 is separated from the upper fixed plate 20. By reducing mechanical interference, the production efficiency of the injection mold 90 can be improved, ensuring the smooth removal of the molded product, and ultimately improving the overall production efficiency and product quality.

[0029] Please see Figure 2In one embodiment of this application, the second end 112 is provided with a snap-fit ​​groove 1121 corresponding to the protrusion 101. The groove wall of the snap-fit ​​groove 1121 is recessed with a groove 1122 in the direction away from the protrusion 101. The protrusion 101 is provided with an opening 1011 corresponding to the groove 1122. At least a portion of the snap-fit ​​mechanism 120 extends out of the opening 1011 and elastically abuts against the groove wall of the groove 1122. By providing the snap-fit ​​groove 1121, the protrusion 101 can be stably snapped into the second end 112 before the mother template 40 is separated from the upper fixing plate 20, ensuring the reliability and accuracy of the lever mechanism 10 during operation, thereby reducing the risk of failure due to unstable connection. The groove 1122 and the opening 1011 corresponding to the groove 1122 on the groove wall of the snap-fit ​​groove 1121 facilitate the engagement and connection between the snap-fit ​​mechanism 120 and the groove 1122. This also allows the protrusion 101 to move freely within the snap-fit ​​groove 1121, enhancing the system's flexibility and adapting to minor displacements of the mold during operation, ensuring smooth material removal by the robotic arm. The snap-fit ​​mechanism 120 elastically abuts against the groove 1122 through the opening 1011. When the mother mold plate 40 separates from the upper fixed plate 20, the second lever 110 is limited to the mother mold plate 40 by the limiting part 70. At this time, the snap-fit ​​mechanism 120, under elastic action, separates from the groove 1122, thereby separating the first lever 100 from the second lever 110. This design reduces the required operating force, making the operation of the entire mechanism easier and more efficient, ultimately contributing to improved production efficiency and overall mold reliability.

[0030] Please see Figure 2 and Figure 3In one embodiment of this application, the latching mechanism 120 includes a first column 121, a second column 122, and an elastic component 123. The first column 121 is disposed on the protrusion 101. The second column 122 is disposed on the protrusion 101 and located on the side of the first column 121 near the latching groove 1121. The elastic component 123 is disposed on the side of the first column 121 away from the latching groove 1121 and abuts against the first column 121. The elastic component 123 elastically abuts against the second column 122 through the first column 121, and at least a portion of the second column 122 is configured to extend out of the opening 1011 and elastically abut against the groove wall of the groove 1122. Through the mutual cooperation of the first column 121, the second column 122, and the elastic component 123, the latching mechanism 120 further optimizes the performance of the lever mechanism 10. The first column 121 is disposed within the protrusion 101, and the elastic component 123 abuts against the first column 121 to press the second column 122 against the opening 1011 and engage with the groove 1122. Under normal operating conditions, this maintains the stability of the connection between the first lever 100 and the second lever 110. This design prevents accidental loosening during mold operation, improving overall safety. When the mother mold plate 40 separates from the upper fixing plate 20, the limiting part 70 fixes the second lever 110 to the mother mold plate 40. This means that the movement of the upper fixing plate 20 directly causes the separation of the first lever 100 and the second lever 110. During this process, the second column 122 is pushed out of the groove 1122 as the protrusion 101 continues to move away from the engaging groove 1121. This design ensures smooth separation between the first lever 100 and the second lever 110, avoiding problems that could hinder the robot from removing the molded product. Operators can more easily perform maintenance and adjustments, reducing downtime and improving production efficiency. The detachment design of the second column 122 can improve the occurrence of jamming or sticking when the mold is separated.

[0031] Please see Figure 3In one embodiment of this application, the protrusion 101 is provided with a first sliding groove 1012 and a second sliding groove 1013 that are interconnected. A three-dimensional coordinate system is established with a first direction Z, a second direction X, and a third direction Y that are mutually perpendicular. The first sliding groove 1012 allows the first column 121 to slide along the first direction Z, and the second sliding groove 1013 allows the second column 122 to slide along the second direction X. The first direction Z is perpendicular to the axial direction of the first column 121, and the second direction X is perpendicular to both the first direction Z and the axial direction of the second column 122. The independent sliding mechanism of the first column 121 and the second column 122 enables the lever to move more precisely. By setting the first slide groove 1012 and the second slide groove 1013, the first column 121 and the second column 122 can move within the protrusion 101, so that the second column 122 can elastically abut against the groove 1122, that is, the first column 121 can move up and down within the first slide groove 1012. When the mother template 40 and the upper fixing plate 20 are not separated, the elasticity of the elastic component 123 causes the first column 121 to press against the second column 122 to the opening 1011, or when the mother template 40 and the upper fixing plate 20 are separated, the pressure of the second column 122 causes the first column 121 to press against the elastic component 123 to a compressed state. The second column 122 can move left and right within the second slide groove 1013. When the mother template 40 and the upper fixing plate 20 are not separated, the second column 122 can be elastically supported by pressing against the groove 1122 in the opening 1011, or when the mother template 40 and the upper fixing plate 20 are separated, it can be pushed out of the groove 1122 and retracted to the opening 1011.

[0032] Please see Figure 3 In one embodiment of this application, there are two first pillars 121 and two second pillars 122. The axes of the two first pillars 121 are parallel to each other. There are two second sliding grooves 1013, each communicating with a first sliding groove 1012. The two second pillars 122 are respectively disposed within the two second sliding grooves 1013, and each second pillar 122 abuts against the two first pillars 121. There are two openings 1011, each communicating with a second sliding groove 1013, and each second pillar 122 extends out of the two openings 1011. By providing two first pillars 121 and two second pillars 122, the elastic component 123 can transmit power between them more precisely, increasing the transmission between the first pillars 121 and the second pillars 122 and facilitating control.

[0033] Please see Figure 4 and Figure 5In one embodiment of this application, the protrusion 101 further includes a through groove 1014, and an elastic component 123 is disposed within the through groove 1014. The through groove 1014 communicates with the first sliding groove 1012. The elastic component 123 abuts against the first column 121 and is used to press the first column 121 in a first direction, so that the second column 122 moves toward the opening 1011. By abutting against the first column 121, the elastic component 123 can effectively transmit elastic force to the first column 121, allowing it to slide autonomously along the first direction.

[0034] Please see Figure 3 , Figure 4 and Figure 5 In one embodiment of this application, the elastic component 123 includes an elastic element 1231 and a fixing element 1232. One end of the elastic element 1231 abuts against the first column 121, and the other end of the elastic element 1231 abuts against the fixing element 1232. The fixing element 1232 is disposed in the through groove 1014 and is used to fix the elastic element 1231 in the through groove 1014. The elastic component 123 functions so that the movement of the first column 121 can directly affect the movement of the second column 122 toward the opening 1011 in a second direction. This coordination ensures that the interaction between the two columns is smooth during the separation process of the mother template 40 and the upper fixing plate 20, which helps to improve the overall operating performance of the lever mechanism 10.

[0035] Please see Figure 4 and Figure 5 In one embodiment of this application, there is a gap between the protrusion 101 and the snap-fit ​​groove 1121.

[0036] Please see Figure 6 This application also provides an injection mold 90, including an upper fixed plate 20, a stripping plate 30, a female mold plate 40, a male mold plate 50, and a lower fixed plate 60 stacked sequentially along a first direction. The injection mold 90 also includes the aforementioned lever mechanism 10. The first lever 100 of the lever mechanism 10 is fixed to the upper fixed plate 20, and the second lever 110 of the lever mechanism 10 is fixed to the female mold plate 40. By setting the integrated lever into two parts, stable opening and closing between the first lever 100 and the second lever 110 is ensured, preventing obstruction of the robot arm from removing the material head, resulting in a simple structure. The limiting part 70 can also control the movement distance of the second lever 110.

[0037] Please see Figure 6 In one embodiment of this application, the injection mold 90 further includes a slider 80 slidably disposed within the mother mold 40. The slider 80 is provided with a limiting groove 801 that is inclined relative to the first direction. The second lever 110 is provided with an insertion part 113 corresponding to the limiting groove 801. The insertion part 113 is configured to be inserted into the limiting groove 801.
