Description

Technical Field

[0001] The utility model relates to the field of edge material grabbing devices, in particular to an edge material grabbing mechanism for an injection molding machine. Background Art

[0002] The residual amount of the injection molding machine refers to the amount of plastic material remaining inside the injection molding machine during the injection molding production process. During the production process, the injection molding machine must inject the plastic material into the mold, but due to the design of the injection molding machine and the mold, a certain amount of plastic will remain in the injection molding machine during the injection process. The residual plastic will occupy the space of the injection molding machine, resulting in reduced production efficiency and increased production costs. In addition, this part of the residual plastic will become "foreign matter" in the next production, affecting product quality and resulting in unqualified products.

[0003] In order to ensure the quality of injection molded products, the scraps of the injection molding machine are usually taken out by grabbing equipment, and the scraps and new materials are mixed in a certain proportion to form new injection molding raw materials. This can also reduce the cost of use. Usually, when grabbing the scraps, a lift is used to move the clamp up and down to take out the scraps. However, if the scraps are large in size, it is difficult for the clamp to hold them firmly, and they may fall off, affecting the overall production efficiency. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, an edge material grabbing mechanism for an injection molding machine includes a lifting rod 1, which can be controlled to move up and down by an electric push rod, a clamping jaw 2 is fixedly installed at the lower end of the lifting rod 1, and the clamping jaw 2 is an automatic mechanical clamping jaw 2, and its opening and closing are set by a program, a plurality of extrusion rods 3 are fixedly installed on the inner side of the clamping jaw 2, and are arranged on the surface of each claw hand, the extrusion rods 3 are arranged in a rectangular array on the inner side of the clamping jaw 2, and the ends of the extrusion rods 3 are set to be sharp to ensure greater pressure when pressure is applied, a push plate 4 is arranged inside the clamping jaw 2, and the push plate 4 is located between two adjacent claw hands of the clamping jaw 2, and will not affect the closing of the clamping jaw 2, and a moving component is installed on the surface of the push plate 4 for moving the push plate 4 longitudinally.

[0020] Since the scraps are produced by injection molding, they are all made of plastic. When they need to be grabbed, the lifting rod 1 moves downward to a suitable position, and the jaws 2 open to grab the scraps. At this time, since the end of the extrusion rod 3 is sharp, it will directly penetrate into the interior of the scraps, thereby improving the connection stability between the jaws 2 and the scraps, thereby preventing the scraps from falling. Then the lifting rod 1 moves to a suitable position, the jaws 2 open, and the push plate 4 moves, which can ensure that the scraps fall off and will not affect reuse, thereby ensuring a smooth operation process and improving production efficiency.

[0021] The moving component includes a mounting plate 5, which is connected to the lifting rod 1 through the mounting component. The mounting plate 5 is not fixedly connected to the lifting rod 1. A connecting rod 6 is fixedly installed on the surface of the mounting plate 5, one end of the connecting rod 6 is fixed to the surface of the push plate 4, and the movement of the mounting plate 5 drives the movement of the push plate 4 through the connecting rod 6. A baffle plate 7 is provided on the outside of the lifting rod 1, and the baffle plate 7 is installed on the surface of an external fixing part, that is, the baffle plate 7 is always in a fixed position and does not move. The mounting component includes a connecting spring 8 and a fixing plate 9, and the fixing plate 9 is fixedly installed on the surface of the lifting rod 1, one end of the connecting spring 8 is installed on the surface of the fixing plate 9, and the other end of the connecting spring 8 is fixed to the surface of the mounting plate 5.

[0022] The mounting plate 5 moves with the lifting rod 1 until it moves to the position of the baffle 7. The baffle 7 rests against the surface of the mounting plate 5, so that the lifting force of the lifting rod 1 causes the mounting plate 5 to move. At this time, the connecting spring 8 is in a stretched state, and the push plate 4 moves downward relative to the lifting rod 1, so that the scraps can be pushed off the surface of the clamping jaw 2. The structure is very simple and easy to use.

[0023] The mounting plate 5 and the fixed plate 9 are both annular sleeves, and the mounting plate 5 is movably sleeved on the surface of the lifting rod 1. The outer diameter of the mounting plate 5 is larger than the outer diameter of the fixed plate 9. The baffle plate 7 is also configured as an annular sleeve. When the baffle plate 7 is against the surface of the mounting plate 5, the upper surface of the mounting plate 5 is fully stressed, ensuring that the mounting plate 5 is uniformly stressed. The baffle plate 7 is sleeved on the surface of the lifting rod 1, and the outer diameter of the baffle plate 7 is the same as the outer diameter of the mounting plate 5. The connecting spring 8 is arranged between the baffle plate 7 and the lifting rod 1. There are multiple connecting springs 8, and the annular array is on the surface of the mounting plate 5.

[0024] A through hole 10 is provided on the surface of the baffle 7, and a guide rod 11 is fixedly installed on the surface of the mounting plate 5. One end of the guide rod 11 movably passes through the through hole 10 and extends to the top of the baffle 7. The guide rod 11 limits the movement of the mounting plate 5 to ensure the moving path of the mounting plate 5 and prevents the baffle 7 from being stuck on the connecting spring 8 after the connecting spring 8 is stretched, thereby indirectly ensuring safe use.

[0025] It should be noted that the utility model is a scrap grabbing mechanism for an injection molding machine. When in use, since the scraps are produced by injection molding, they are all made of plastic. When it is necessary to grab the scraps, the lifting rod 1 moves downward to a suitable position, and the jaws 2 open to grab the scraps. At this time, since the end of the extrusion rod 3 is sharp, it will directly penetrate into the interior of the scrap, thereby improving the connection stability between the jaws 2 and the scrap, thereby preventing the scrap from falling. Then the lifting rod 1 moves to a suitable position, the jaws 2 open, and the mounting plate 5 moves with the lifting rod 1 until it moves to the position of the baffle 7, and the baffle 7 rests on the surface of the mounting plate 5. At this time, the connecting spring 8 is slowly stretched, and the push plate 4 moves downward relative to the lifting rod 1, so that the scraps can be pushed off the surface of the jaws 2. When the baffle 7 is not needed, the mounting plate 5 will return to the initial position due to the rebound force of the connecting spring 8, thereby ensuring normal use next time.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
