Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a device for crushing residual material from injection molding machines. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] During the use of injection molds, the material needs to be heated and converted into a fluid before being molded again. During the injection process, leftover material is often generated. This leftover material is usually crushed and melted into a liquid state for reuse. However, since the volume of the leftover material is usually small, when the leftover material is crushed by a crusher, the debris often flies out of the equipment, which can easily injure the staff and is inconvenient to clean up. At the same time, traditional crushers do not crush the material evenly enough, which requires more time to melt and results in energy waste. Utility Model Content

[0015] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to Figures 1 to 4 As shown, the present invention provides a waste material crushing device for injection molding machines, comprising a base 4, an anti-splash crushing mechanism, a secondary crushing mechanism, and a collecting mechanism. The anti-splash crushing mechanism is disposed on one side of the base 4, and the collecting mechanism is disposed on the other side of the base 4. The anti-splash crushing mechanism is connected to the secondary crushing mechanism, and the secondary crushing mechanism is connected to the collecting mechanism. The anti-splash crushing mechanism includes a feed pipe 10, a conveying pipe 9, a pushing assembly, a first crushing box 7, and a first crushing assembly. The conveying pipe 9 is installed on the other side of the base 4 via a support frame 13. The feed pipe 10 is provided on the upper part of the conveying pipe 9. The pushing assembly is provided on one side of the conveying pipe 9. A crushing opening is provided on the other side of the conveying pipe 9. The first crushing box 7 is connected to the crushing opening. The first crushing assembly is connected to the first crushing box 7. A discharge port is provided at the lower part of the first crushing box 7. The first crushing box 7 is connected to the upper part of the secondary crushing mechanism through the discharge port.

[0017] The working principle of this utility model is as follows: When it is necessary to crush the surplus material during the actual injection molding process, the surplus material can be put into the inside of the conveying pipe 9 through the feed pipe 10. Then, the pusher component is operated to push the surplus material to the crushing port. When the surplus material passes through the crushing port, it is crushed by the first crushing component and the crushed surplus material falls into the secondary crushing mechanism. The surplus material is crushed in the semi-enclosed conveying pipe 9 and the first crushing box 7 to prevent the fragments from flying out. Then, the fragments are crushed by the secondary crushing mechanism and collected by the collection mechanism after crushing.

[0018] Furthermore, the pushing assembly includes a linear pushing component 8 and a pushing plate 16. The linear pushing component 8 is installed on one side of the conveying pipe 9, and the pushing plate 16 is slidably connected to the inside of the conveying pipe 9. The linear pushing component 8 and the pushing plate 16 are linearly driven connected.

[0019] As can be seen from the above description, when it is necessary to push the surplus material, the linear pusher 8 can be operated, so that the linear pusher 8 drives the pusher plate 16 to move in the conveying pipe 9, and pushes the surplus material through the pusher plate 16.

[0020] Furthermore, the first crushing assembly includes a first rotating drive 5 and a crushing disc 15. The first rotating drive 5 is installed on the outside of the first crushing box 7, and the crushing disc 15 is disposed on the outside of the crushing opening. The first rotating drive 5 and the crushing disc 15 are rotatably connected.

[0021] As can be seen from the above description, when the residual material passes through the crushing opening, the first rotating drive component 5 drives the crushing disc 15 to rotate, and the crushing disc 15 crushes the residual material.

[0022] Furthermore, it also includes a feed hopper 11, which is fixedly connected to the feed pipe 10.

[0023] As can be seen from the above description, it is beneficial for the residual material to enter the feed pipe 10 better.

[0024] Furthermore, the secondary crushing mechanism includes a second crushing box 6, a second rotating drive component 17, a rotating shaft 18, and crushing blades 19. The top of the second crushing box 6 is provided with a feed inlet, and the first crushing box 7 is connected to the feed inlet through the discharge port. The bottom of the second crushing box 6 is equipped with the second rotating drive component 17. The rotating shaft 18 is rotatably installed inside the second crushing box 6. The second rotating drive component 17 is drivenly connected to the rotating shaft 18. A plurality of crushing blades 19 are arranged around the middle of the rotating shaft 18.

[0025] As can be seen from the above description, the residual material that is conducive to the completion of crushing slides into the second crushing box 6 after entering the first crushing box 7. At the same time, the second rotating drive 17 is operated, so that the second rotating drive 17 drives the crushing blade 19 to rotate through the rotating shaft 18, and crushes the crushed residual material through the crushing blade 19. Then, the crushed residual material enters the collection mechanism under the traction of the collection mechanism.

[0026] Furthermore, it also includes shovels 21, and a plurality of shovels 21 are arranged around the lower part of the rotating shaft 18, and the shovels 21 are connected to the bottom of the inner surface of the second crushing box 6.

[0027] As can be seen from the above description, it is beneficial to use the shovel 21 to scoop up large particles of material from the bottom of the second crushing box 6 and crush them through the crusher, so as to avoid the accumulation of large particles of material at the bottom of the second crushing box 6 and to make the remaining material more effectively crushed.

[0028] Furthermore, the collection mechanism includes a collection box 2, an exhaust component 1, a valve body 20, a filter element 14, and a collection box 3. The upper part of the collection box 2 is provided with an exhaust port, and the exhaust component 1 is connected to the exhaust port through the filter element 14. The lower part of the collection box 2 is connected to the collection box 3 through a connecting pipe, and the valve body 20 is provided inside the connecting pipe. The collection box 2 is connected to the upper part of the second crushing box 6 through a suction pipe 12.

[0029] As can be seen from the above description, when it is necessary to collect the crushed residue, the exhaust device 1 can be operated to discharge the air in the collection box 2 through the exhaust port, so that the inside of the collection box 2 enters a negative pressure state. At the same time, the collection box 2 sucks the small particles of crushed material in the second crushing box 6 into the collection box 2 through the suction pipe 12. Meanwhile, the exhaust device 1 is protected by the filter element 14. After a certain amount of residue is collected in the collection mechanism, the exhaust device 1 is stopped and the valve body 20 is opened to allow the small particles of crushed material to enter the smelting machine for smelting. The collection box 2 is connected to the upper part of the second crushing box 6 through the suction pipe 12, so that the residue will be absorbed by the suction pipe 12 only after it is crushed to a sufficiently small size.

[0030] Furthermore, it also includes a controller, which is electrically connected to the anti-splash crushing mechanism, the secondary crushing mechanism, and the collecting mechanism, respectively.

[0031] As can be seen from the above description, it makes it more convenient for users to control the overall device. Example 1
