[0002] Injection molded parts refer to various injection molded products produced by injection molding machines, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene with a variety of organic solvents added. Since injection molded parts often have casting materials remaining at the gate, the molded injection molded parts also require staff to use nozzle pliers to cut the remaining waste.

[0003] At present, the existing nozzle pliers have a relatively simple structure. In the actual process of shearing waste, since the sheared waste has a large kinetic energy and there are no obstructions around it, the sheared waste will splash, which will not only pollute the working environment, but also accidentally splash on the staff, thus posing a certain safety hazard. For this reason, we propose an injection molded parts shearing device to solve the above problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A shearing device for injection molded parts includes a shearing nozzle 1. There are two groups of shearing nozzles 1, and the two groups of shearing nozzles 1 are connected by a rotating shaft 2. The sides of the two groups of shearing nozzles 1 are connected with a second spring 15. Through the setting of the second spring 15, the two groups of handles 3 can be automatically reset after the force stops, so as to reduce the labor intensity of the staff at work. The ends of the two groups of shearing nozzles 1 are respectively connected with handles 3. The connection method of the handles 3, the shearing nozzles 1 and the rotating shaft 2 is the existing technology, which will not be repeated here. The sides of the two groups of shearing nozzles 1 are respectively provided with clamps 4. Through the setting of the two groups of clamps 4, the waste can be clamped while cutting to prevent the waste from splashing wantonly after the shearing is completed, which can protect the working environment and prevent the staff from being accidentally injured.

[0024] Further, see Figure 2 , Figure 3 and Figure 4 It can be known that a support plate 5 is provided on the side of the shearing nozzle 1, and a card slot 13 is symmetrically opened inside the support plate 5, and a connecting rod 10 is inserted inside the card slot 13, and one end of the connecting rod 10 is connected to the clamping plate 4, and the other end of the connecting rod 10 is fixedly connected to the limit block 11, and the side of the limit block 11 is connected to a first spring 12, and the other end of the first spring 12 is connected to the support plate 5. In the process of clamping the waste, the clamping plate 4 is able to be subjected to force and contact the waste, and the clamping plate 4 is able to push the connecting rod 10 to slide inside the card slot 13. The mutual cooperation between the connecting rod 10 and the support plate 5 can meet the movement requirements of the clamping plate 4, and the first spring 12 sleeved on the side of the connecting rod 10 can keep the clamping plate 4 in a state of clamping the waste, thereby effectively meeting the clamping requirements for waste of different specifications.

[0025] Further, see Figure 3 It can be known that the bottom end of the support plate 5 is connected to the docking plate 6, and the interior of the docking plate 6 is connected to the shearing nozzle 1 through the bolt 14. When in use, the installation and disassembly of the support plate 5 together with the clamping plate 4 can be realized through the mutual cooperation of the docking plate 6 and the bolt 14. When the shearing nozzle 1 is damaged, it can be installed on a new set of shearing nozzles 1 for use, thereby effectively reducing the waste of resources.

[0026] Further, see Figure 2 and Figure 3It can be known that a snap block 7 is connected to the side of the shearing nozzle 1, and the snap block 7 is arranged as a U-shaped structure. When in use, the snap block 7 arranged in the U-shaped structure can be used to pre-position the support plate 5 and the docking plate 6 that are docked with the shearing nozzle 1, so that the support plate 5 and the shearing nozzle 1 can be docked and installed later.

[0027] Further, see Figure 3 and Figure 4 It can be seen that grooves are evenly opened at the bottom end of the splint 4, and the inner walls of the grooves are installed with balls 9. When in use, the grooves and balls 9 cooperate with each other to prevent the bottom end of the splint 4 from directly rubbing against the blade, so as to prevent scratches on the blade of the shear nozzle 1, thereby ensuring the sharpness of the shear nozzle 1.

[0028] Further, see Figure 2 and Figure 4 It can be seen that rubber plates are glued to the sides of the two groups of clamps 4 that are close to each other, and anti-slip strips 8 are evenly distributed on the sides of the rubber plates. When in use, the clamping effect of the waste can be improved by setting the rubber plates and multiple groups of anti-slip strips 8.

[0029] Further, see Figure 2 It can be seen that the clamping plate 4 is set to a rectangular structure, and the length of the clamping plate 4 is matched with the length of the blade of the shearing nozzle 1. Since the length of the clamping plate 4 is the same as the blade, the waste in the shearing process can be fully clamped to improve the reliability of the device when used. The clamping force of the waste can be further improved by setting the clamping plate 4 in a rectangular shape.

[0030] Working principle: When the utility model is in use, the staff can hold the handle 3 and align the shearing nozzle 1 with the waste, and then pinch the two groups of handles 3 to move closer to each other, so that the two groups of shearing nozzles 1 can shear the waste. When the two groups of handles 3 are moved closer to each other and drive the two groups of shearing nozzles 1 to move closer to each other, the two groups of clamps 4 set on the sides of the shearing nozzle 1 can be moved at the same time to clamp the waste. Through the setting of the two groups of clamps 4, the sheared waste can be fixed to effectively prevent it from splashing. In addition, when clamping some larger waste, the two groups of clamps 4 can push the connecting rod 10 to slide inside the support plate 5, thereby satisfying the clamping effect for waste of different specifications. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
