Specific implementation manner

[0026] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0027] Please refer to Figures 1-6 , the present application provides an injection molded part processing shearing mechanism, including a shearing component 10 and a material receiving component 20.

[0028] Among them, the shearing component 10 can position the injection molded part and cut the sprue of the injection molded part, and the material receiving component 20 can collect the waste cut from the injection molded part.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the shearing component 10 includes a frame body 110, a positioning part 120 is installed on the top of the frame body 110, a shearing frame 130 is installed on the frame body 110, a material discharging opening 131 is provided on the top support plate of the shearing frame 130, a workpiece placement plate 150 is arranged at the material discharging opening 131 of the shearing frame 130, and the workpiece placement plate 150 covers half of the material discharging opening 131, and a shearing part 140 is installed at the front end of the shearing frame 130; among them, the side of the injection molded part with the sprue is placed downward on the workpiece placement plate 150, then the positioning part 120 is started to press the injection molded part by the positioning part 120, and then the shearing part 140 is started, and the shearing part 140 cuts off the sprue of the injection molded part, and the cut surplus material falls.

[0030] In this embodiment, the positioning member 120 includes a cylinder 121. The cylinder 121 is installed on the top of the frame body 110, and the rod end of the cylinder 121 movably penetrates through the top wall of the frame body 110 and is connected with a pressing plate 123, and the pressing plate 123 can press the injection molded part. The rod end of the cylinder 121 is connected with an elastic plate 122, and the pressing plate 123 is connected with the elastic plate 122. Auxiliary guiding members are installed at both ends of the elastic plate 122, and the top ends of the auxiliary guiding members movably penetrate through the top wall of the frame body 110. Among them, when the cylinder 121 is started, the rod end of the cylinder 121 extends so that the pressing plate 123 presses on the injection molded part, and the elastic plate 122 can make the pressure of the pressing plate 123 on the injection molded part a flexible pressure, preventing the injection molded part from being damaged by pressing.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the material receiving assembly 20 includes a material receiving box 210. The material receiving box 210 is detachably arranged inside the shearing frame 130 and is located directly below the material discharging port 131. Among them, the remaining material cut from the sprue of the injection molded part falls through the material discharging port 131 and just drops into the material receiving box 210 for collection. By arranging the material receiving box 210 directly below the material discharging port 131, the remaining material cut from the sprue of the injection molded part can be automatically collected without separate cleaning, improving the shearing efficiency of the injection molded part. By the detachable connection between the material receiving box 210 and the shearing frame 130, it is convenient to dump the remaining material inside the material receiving box 210.

[0032] In this embodiment, a slider 230 is fixedly connected to the bottom of the material receiving box 210. An open sliding groove matching with the slider 230 is formed in the bottom plate of the shearing frame 130. A baffle is fixedly connected to the rear side wall of the material receiving box 210. The baffle can be attached to the rear side of the shearing frame 130, so that when the material receiving box 210 is pushed into the shearing frame 130, it will not be pushed in too much, affecting the shearing of the shearing part 140. A rubber pad 240 is arranged at the bottom of the slider 230. A handle 220 is installed on the rear side of the material receiving box 210. A deflector 250 is fixedly connected to the front side wall of the material receiving box 210 below the material discharging port 131. Among them, when the remaining material after the sprue is sheared falls through the material discharging port 131, the remaining material is guided into the material receiving box 210 under the action of the deflector 250. When the remaining material inside the material receiving box 210 needs to be dumped, hold the handle 220, and the material receiving box 210 is pulled out from inside the shearing frame 130 under the cooperation of the slider 230 and the sliding groove, and then the remaining material is dumped. After the dumping is completed, hold the handle 220 again, align the slider 230 with the sliding groove, and push the material receiving box 210 into the shearing frame 130.

[0033] The working principle of this injection molded part processing and shearing mechanism:

[0034] Place the side of the injection molded part with the sprue downward on the workpiece placement plate 150, then start the positioning member 120 so that the positioning member 120 presses the injection molded part tightly, and then start the shearing member 140. The shearing member 140 cuts off the sprue material on the injection molded part, and the cut-off surplus material falls. The surplus material cut from the sprue of the injection molded part falls through the material discharge port 131 and just drops into the inside of the material receiving box 210 for collection. By arranging the material receiving box 210 directly below the material discharge port 131, the surplus material cut from the sprue of the injection molded part can be automatically collected without separate cleaning, improving the shearing efficiency of the injection molded part. By the detachable connection between the material receiving box 210 and the shearing frame 130, it is convenient to dump the surplus material inside the material receiving box 210.

[0035] It should be noted that the specific model specifications of the air cylinder 121 and the shearing member 140 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0036] The power supply and its principle of the air cylinder 121 and the shearing member 140 are clear to those skilled in the art and will not be described in detail here.

[0037] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
