[0002] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force.

[0003] By restricting the boundaries of the material and then pressing it into shape, products with fixed boundaries, such as shoe soles, can be manufactured in this way. However, due to the limitation of the injection hole, the finished product has a protruding part, which is traditionally removed manually. This process is too cumbersome and dangerous, and it is not conducive to continuous and efficient processing and production.

[0004] Therefore, a fully automatic gate shearing device for supercritical molding products is proposed to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 The fully automatic gate shearing device for supercritical molding products in this embodiment includes a processing turntable 1 and a plurality of processing holes 101 that are uniformly and circularly penetrating the upper end of the processing turntable 1. A molding mechanism is provided above the processing holes 101.

[0027] The forming mechanism includes an upper template 3 and a lower template 301. The lower template 301 is installed on the upper part of the processing turntable 1. A support platform 2 for positioning and pressing support is connected in the middle of the processing turntable 1. The support platform 2 extends from one side of the processing turntable 1 to its outer side. One of the processing holes 101 and a set of forming mechanisms are located below the support platform 2.

[0028] One of the machining holes 101 has a mold opening frame 5 installed inside for mold opening support. A positioning and clamping mechanism is provided above the mold opening frame 5, and a trimming mechanism is provided on the side of the mold opening frame 5.

[0029] First, by using an existing injection molding device, the material is filled from the middle of the upper mold plate 3 into the injection space formed between the upper mold plate 3 and the lower mold plate 301. Then, driven by the rotating device at the lower end of the processing turntable 1, the upper mold plate 3 and the lower mold plate 301 to be injected are moved downwards towards the support platform 2, and the injection molding is promoted by the pressing of the inner pressing device below it. Since the injection molding device, the rotating drive device and the pressing device can all be used with conventional solutions and are commonly used existing technologies, they are not described in detail in this embodiment.

[0030] After the upper template 3 and the lower template 301 are pressed, under the continuous rotation of the processing turntable 1, the upper template 3 and the lower template 301 are cooled by continuous rotation and gradually move to the processing hole 101 with the mold opening frame 5. Under the push of the mold opening frame 5, the upper template 3 moves upward to form a demolding effect. Then, under the clamping movement of the positioning clamping mechanism, the molded product moves into the trimming mechanism and the excess connecting parts are trimmed and removed. Finally, under the release of the positioning clamping mechanism, the product automatically falls and is collected.

[0031] Thus, by pressing and molding the upper template 3 and the lower template 301, and by rotating and cooling them multiple times, the precision of the product molding boundary in the middle is ensured. With the precise movement support of the positioning and clamping mechanism and the shearing support of the trimming mechanism, the protruding parts are accurately trimmed during the injection molding process, improving the precision and stability of the molded product and enabling the device to operate efficiently like an assembly line.

[0032] The upper template 3 and the lower template 301 are rotatably connected on one side of their upper surfaces. The upper template 3 and the lower template 301 are formed by injection molding and die casting to create symmetrically connected molded parts 302.

[0033] The upper template 3 is provided with limiting rods 303 on both sides for limiting support. The limiting rods 303 are located above the mold opening frame 5. The lower end of the mold opening frame 5 is provided with a driving source.

[0034] By setting a simple drive source such as a motor or cylinder with telescopic drive, the mold opening frame 5 can be driven to move up and down. Therefore, it is not limited here. Based on the limit rod 303 and the limit of the mold opening frame 5, it is reliable to push it to move.

[0035] When the mold opening frame 5 moves upward, it pushes the limit rod 303 up and down synchronously. Under the rotational connection between the upper mold plate 3 and the lower mold plate 301, the upper mold plate 3 is pushed upward, so that the molded product 302 is exposed, which facilitates the subsequent clamping and movement of the molded product 302.

[0036] After the molded part 302 is moved to one side, the mold opening frame 5 is reset, and the upper mold plate 3 falls automatically under its own weight, so that the injection support space is formed again between the upper mold plate 3 and the lower mold plate 301. The positioning support of the recessed part of the inner wall of the upper mold plate 3 ensures the stability and reliability of injection molding.

[0037] The positioning and clamping mechanism consists of a positioning part and a clamping part, and both the positioning part and the clamping part are connected to the side of the support table 2 through the robot arm 4, and the positioning and clamping mechanism is located above the processing turntable 1.

[0038] The positioning part includes a camera 401 installed on one side of the robotic arm 4. The camera 401 is located above the forming mechanism. The clamping part includes a support frame 402 installed at the lower end of the robotic arm 4. A rotary motor 403 for rotating support is provided on the side of the support frame 402. A threaded rod that is rotatably installed at the lower end of the support frame 402 is installed at the output end of the rotary motor 403.

[0039] The threaded rod rotates through the support block 404 installed at the lower end of the support frame 402. The threaded rod is threadedly connected to the movable gripper 405, which consists of two grippers. The outer side of the support frame 402 is equipped with a movable component 407, and the output end of the movable component 407 is equipped with a fixed gripper 406.

[0040] By combining the positioning part and the clamping part, the distance between the two molded products 302 is determined by the camera 401, providing precise support for the position adjustment of the moving gripper 405, and providing adjustment support for the moving gripper 405 under the drive of the rotating motor 403 and the rotation support of the support block 404.

[0041] Specifically, by transmitting the information captured by the camera 401 to a control terminal on one side, the rotation motor 403 is controlled to rotate and run according to the distance between the two molded products 302 captured by the camera. The threaded rod on its output end is rotated and adjusted, so that the moving jaw 405 moves a distance, thereby moving the distance between the moving jaw 405 and the fixed jaw 406 and the distance between the protruding parts of the two molded products 302 below, thus improving the accuracy of clamping the two molded products 302.

[0042] By setting the position of the fixed gripper 406 to fixed and the position of the movable gripper 405 to adjustable, the space between the movable gripper 405 and the fixed gripper 406 can be used in multiple ranges, enabling accurate clamping of molded products 302 of different specifications and ensuring the range of use of the device. Under the vertical movement drive and clamping movement drive of the movable component 407, and with the movable component 407 also set between the movable gripper 405 and the threaded rod, the accurate movement of the two sets of movable grippers 405 and fixed grippers 406 is ensured. The internal drive method of the movable component 407 is all existing technology and can be driven by a variety of different methods, so it is not described in detail in this embodiment.

[0043] The trimming mechanism includes a fixed frame 6 for fixed support, with trimmers 601 installed at both ends of the outer side of the fixed frame 6, and a collection frame 602 provided below the middle of the two trimmers 601;

[0044] The fixed support of the fixing frame 6 provides fixed support for the trimming of the trimming shears 601, and the two trimmed parts are collected simultaneously under the collection support of the collection box 602.

[0045] In this embodiment, the molded product 302 can be moved by the movable support of the robotic arm 4 itself, or the trimming shears 601 can be combined with the drive device to have a movable adjustment effect. Both methods can trim molded products 302 of different specifications. The appropriate adjustment method can be selected according to the actual situation, so it is not limited in this embodiment, thereby ensuring the accuracy of trimming the molded product 302.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
