[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4The utility model provides a technical solution: a mechanism with automatic air shearing nozzle, which is composed of a base 1 and several groups of pneumatic shearing modules 2. The base 1 serves as a supporting platform for the entire mechanism, and several groups of pneumatic shearing modules 2 are installed on the upper part of the base 1. Each group of pneumatic shearing modules 2 can work independently to accurately shear the nozzle of the injection molded shell.

[0021] A base 21 is provided at the bottom of the pneumatic shearing module 2 for installing and fixing other components. The design of the base 21 is sturdy and durable and can withstand the force generated by the cylinder 22 and the cutter 23 during operation. The cylinder 22 is installed on the side of the base 21 to drive the cutter 23 to perform translational movement. The selection of the cylinder 22 should ensure sufficient driving force and stability to meet the needs of the shearing work. The cutter 23 is a key component of the shearing work and its cutting edge needs to be sharp and durable. The cutter 23 is installed at the telescopic end of the cylinder 22. Driven by the cylinder 22, the cutter 23 can be translated to the inside of the injection molded shell to shear the connection between the injection molded shell and the sprue. The workstation 24 is installed on the upper part of the base 21 and is located on the rear side of the cutter 23. The workstation 24 is designed to position and support the injection molded shell to ensure the accuracy and stability of the shearing work. The limit block 26 is installed on the upper part of the base 21 and on the side away from the cylinder 22. The function of the limit block 26 is to limit the lateral movement of the cutter 23 to prevent the cutter 23 from being offset or damaged during the shearing process. To ensure the smooth sliding of the cutter 23, a linear guide 25 is also installed on the upper part of the base 21. The cutter 23 slides on the upper part of the linear guide 25, making the shearing process more accurate and stable.

[0022] The cutter 23 includes a cutter holder 231 slidably connected to the upper portion of the linear guide 25. A handle 232 is connected to the upper portion of the cutter holder 231, and a blade 233 is disposed at the top of the handle 232. The blade 233 is the direct actuator for shearing, and its material and shape are selected to ensure shearing efficiency and quality. A retaining post 221 is connected to the telescopic end of the cylinder 22, and a retaining slot 234 is defined at the end of the cutter holder 231. The retaining post 221 engages within the retaining slot 234. This retaining connection ensures that the cutter 23 is securely connected to the telescopic end of the cylinder 22, ensuring stability and reliability of the shearing operation.

[0023] Workstation 24 includes a base 241 mounted on top of base 21. A limiting stud 242 is connected to the top of base 241, and a locking protrusion 243 is symmetrically connected to the top of limiting protrusion 242. Base 241 is a semi-rectangular structure, while limiting stud 242 is a semi-cylindrical structure. Before shearing, the injection molded shell is fitted over limiting stud 242 and locking protrusion 243, with limiting stud 242 occupying half of the shell's interior volume. This design ensures stability and accuracy during the shearing process.

[0024] When the mechanism is used to shear the nozzle 31 in the injection molded shell 3, firstly, a plurality of injection molded shells 3 with nozzles 31 are placed on a plurality of stations 24. After being placed in place, the knife handle 232 is located inside the injection molded shell 3, and the blade 233 is located on the side of the nozzle 31 (as shown in the attached figure). Figure 4 As shown), the cylinder 22 then extends, pushing the tool 23 to move along the direction of the linear guide rail 25, thereby using the blade 233 to shear the sprue 31 from the injection molded shell 3. After shearing into place, the sprue 31 falls off the injection molded shell 3, and the tool holder 231 will abut against the limit block 26. After shearing, it is reset and the cut injection molded shell 3 can be taken away.
