There are spiral stirring blades outside the stirring roller, and the plastic in the injection chamber can be stirred by rotation. The staff starts the first cylinder, and the output end of the first cylinder pushes the stirring roller through a push plate, which can push the plastic in the injection chamber to move towards the injection port while stirring.

[0004] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: When the current plastic injection molding machines on the market are injecting, due to the diversity of plastic modules, different models of injection molding modules need to be quickly replaced to improve the injection efficiency. However, the existing plastic injection molding machines may not be able to quickly replace the modules. In view of the above defects, the plastic injection molding machine is improved to facilitate the staff to quickly replace the module body, thereby improving the usability of the injection molding machine body. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that there is a disadvantage in the prior art that the module may not be quickly replaced. For this reason, we propose a plastic injection molding machine facilitating the replacement of modules.

[0006] To achieve the above object, the present application adopts the following technical solutions: A plastic injection molding machine facilitating module replacement, including an injection molding machine body. A support column is fixedly connected to the top of the injection molding machine body. A support plate is fixedly connected to the top of the support column. A cylinder is fixedly connected to the bottom of the support plate. The output end of the cylinder is fixedly connected to a connecting plate.

An opening groove is opened on the surface of the adjusting housing. A pull rod is slidably connected to the inner diameter of the opening groove. One end of the pull rod close to the sliding piece is fixedly connected to the sliding piece.

[0007] Preferably, first springs are fixedly connected to both sides of the connecting block. One end of the first spring close to the sliding piece is fixedly connected to the sliding piece.

[0008] Preferably, guiding grooves are opened on both sides of the adjusting housing. Guiding blocks are slidably connected to the inner cavities of the guiding grooves. One end of the guiding block close to the fixed rod is fixedly connected to the fixed rod.

[0009] Preferably, a second spring is fixedly connected to the inner cavity of the adjusting housing. The top of the second spring is fixedly connected to the connecting column.

[0010] Preferably, a shaping plate is installed in the inner cavity of the injection molding machine body. A hollow groove is opened inside the injection molding machine body. A hollow plate is slidably connected to the inner cavity of the hollow groove. One end of the hollow plate close to the shaping plate is fixedly connected to the shaping plate.

[0013] The technical effects and advantages of the present utility model:

[0014] In this utility model, the staff horizontally pulls the pull rod, driving the inner cavity of the sliding plate to slide on the surface of the fixed rod. As the sliding plate displaces, the surface of the limiting block driven by the sliding plate gradually disengages from the inner cavity of the limiting groove. At this time, the staff vertically pulls down the pull rod, simultaneously driving the connecting block to slide in the inner cavity of the adjusting housing, causing the sliding plate and the limiting block to gradually disengage from the inner cavity of the limiting housing. At this time, the module body will be unconstrained, and the module body can be replaced. Through the setting of the above structure, it is convenient for the staff to quickly replace the module body, thereby improving the usability of the injection molding machine body.

[0015] In this utility model, the staff starts the air cylinder, causing the air cylinder to push the connecting plate and the module body to press down. As the connecting plate displaces, the inner cavity of the guiding plate driven by the connecting plate slides on the surface of the guiding rod. As the module body gradually moves downward, the module body drives the shaping plate to move downward for injection molding. At the same time, the shaping plate drives the inner cavity of the hollow plate to slide on the surface of the guiding column, and simultaneously compresses the third spring to store energy. Through the setting of the above structure, when the staff starts the air cylinder again, causing the connecting plate and the module body to move upward, at this time, the rebounding force of the third spring continuously pushes the shaping plate to move upward, facilitating the rapid discharging of the shaping plate, thereby improving the production efficiency of the injection molding machine body.

A support column 2 is fixedly connected to the top end of the injection molding machine body 1. A support plate 3 is fixedly connected to the top end of the support column 2. A cylinder 4 is fixedly connected to the bottom end of the support plate 3. The output end of the cylinder 4 is fixedly connected to a connecting plate 5. A module body 6 is installed at the bottom end of the connecting plate 5. An adjusting housing 7 is fixedly connected to the surface of the module body 6. A limiting housing 8 is fixedly connected to the surface of the connecting plate 5. A connecting block 9 is slidably connected to the inner cavity of the adjusting housing 7. A connecting column 10 is fixedly connected to the bottom end of the connecting block 9. Fixed rods 11 are fixedly connected to both sides of the connecting block 9. Sliding plates 12 are slidably connected to the surfaces of the fixed rods 11. Limiting grooves 13 are opened on both sides of the limiting housing 8. Limiting blocks 14 are slidably connected to the inner diameters of the limiting grooves 13. One end of the limiting block 14 close to the sliding plate 12 is fixedly connected to the sliding plate 12. An opening groove 15 is opened on the surface of the adjusting housing 7. A pull rod 16 is slidably connected to the inner diameter of the opening groove 15. One end of the pull rod 16 close to the sliding plate 12 is fixedly connected to the sliding plate 12. When the staff needs to quickly replace the module body 6, the staff horizontally pulls the pull rod 16, driving the inner cavity of the sliding plate 12 to slide on the surface of the fixed rod 11, and at the same time compressing the first spring 17 to store energy. As the sliding plate 12 moves, the surface of the sliding plate 12 drives the limiting block 14 to gradually disengage from the inner cavity of the limiting groove 13. At this time, the staff vertically pulls down the pull rod 16, and at the same time drives the connecting block 9 to slide in the inner cavity of the adjusting housing 7, so that the connecting block 9 compresses the second spring 20 to store energy. As the connecting block 9 moves, the connecting block 9 drives the fixed rod 11 to move, and at the same time drives the surface of the guiding block 19 to slide in the inner cavity of the guiding groove 18. At this time, the sliding plate 12 and the limiting block 14 gradually disengage from the inner cavity of the limiting housing 8. At this time, the module body 6 will be unconstrained, and the module body 6 can be replaced. Through the setting of the above structure, it is convenient for the staff to quickly replace the module body 6, thereby improving the use convenience of the injection molding machine body 1.

[0025] Refer to Figure 4As shown, in this implementation: On both sides of the connection block 9, there are first springs 17 fixedly connected. One end of the first spring 17 close to the sliding piece 12 is fixedly connected to the sliding piece 12. The staff horizontally pulls the pull rod 16, driving the inner cavity of the sliding piece 12 to slide on the surface of the fixed rod 11, and at the same time compressing the first spring 17 to store energy. Through the setting of the first spring 17, the rebounding force of the first spring 17 continuously pushes the sliding piece 12 to reset, so that the surface of the limiting block 14 is clamped and limited in the inner cavity of the limiting groove 13.

[0026] Refer to Figure 3 and Figure 4 As shown, in this implementation: On both sides of the adjustment housing 7, there are guiding grooves 18 opened. A guiding block 19 is slidably connected in the inner cavity of the guiding groove 18. One end of the guiding block 19 close to the fixed rod 11 is fixedly connected to the fixed rod 11. As the staff vertically pulls the pull rod 16, the pull rod 16 drives the fixed rod 11 and the connection block 9 to displace. Along with the displacement of the fixed rod 11, the fixed rod 11 drives the surface of the guiding block 19 to slide in the inner cavity of the guiding groove 18. Through the setting of the above structure, when the connection block 9 displaces, it maintains a directional displacement, preventing the connection block 9 from shifting and affecting the coordination between structures.

[0027] Refer to Figure 4 As shown, in this implementation: In the inner cavity of the adjustment housing 7, there is a second spring 20 fixedly connected. The top of the second spring 20 is fixedly connected to the connection column 10. As the staff vertically pulls down the pull rod 16, it drives the connection block 9 to move downward, and at the same time compresses the second spring 20 to store energy. Through the setting of the second spring 20, the rebounding force of the second spring 20 continuously drives the connection block 9 to reset, and at the same time drives the sliding piece 12 and the limiting block 14 into the inner cavity of the limiting housing 8, so that the surface of the limiting block 14 can accurately be clamped with the limiting block 14.

[0028] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown in the figure, in this embodiment: a shaping plate 21 is installed in the inner cavity of the injection molding machine body 1, a hollow groove 22 is opened inside the injection molding machine body 1, a hollow plate 23 is slidably connected to the inner cavity of the hollow groove 22, one end of the hollow plate 23 close to the shaping plate 21 is fixedly connected to the shaping plate 21, a guide post 24 is fixedly connected to the inner cavity of the hollow groove 22, and the surface of the guide post 24 is slidably connected to the inner cavity of the hollow plate 23. When the staff needs to quickly reset the shaping plate 21 and discharge the material conveniently, the staff starts the cylinder 4, so that the cylinder 4 pushes the connecting plate 5 and the module body 6 downward. As the connecting plate 5 moves, the inner cavity of the connecting plate 5 drives the guide plate 26 to slide on the surface of the guide rod 25. As the module body 6 gradually moves downward, the module body 6 drives the shaping plate 21 to move downward for injection molding, and at the same time, the shaping plate 21 drives the inner cavity of the hollow plate 23 to slide on the surface of the guide post 24, and at the same time, the third spring 27 is compressed to store energy. Through the setting of the above structure, when the staff starts the cylinder 4 again, the connecting plate 5 and the module body 6 move upward. At this time, the rebounding force of the third spring 27 continuously pushes the shaping plate 21 upward, which is convenient for the shaping plate 21 to quickly discharge the material, thereby improving the production efficiency of the injection molding machine body 1.

[0029] Refer to Figure 1 , Figure 2 and Figure 5 As shown in the figure, in this embodiment: a guide rod 25 is fixedly connected to the top of the injection molding machine body 1, a guide plate 26 is slidably connected to the surface of the guide rod 25, and one end of the guide plate 26 close to the connecting plate 5 is fixedly connected to the connecting plate 5. The staff starts the cylinder 4, so that the cylinder 4 drives the connecting plate 5 and the module body 6 to move. As the connecting plate 5 moves, the inner cavity of the connecting plate 5 drives the guide plate 26 to slide on the surface of the guide rod 25. Through the setting of the above structure, when the connecting plate 5 moves, it maintains a directional movement, preventing the connecting plate 5 from shifting and affecting the injection molding effect of the module body 6, thereby affecting the product quality.

[0030] Refer to Figure 6 As shown in the figure, in this embodiment: a third spring 27 is fixedly connected to the inner cavity of the hollow groove 22, and the top of the third spring 27 is fixedly connected to the hollow plate 23. As the shaping plate 21 moves downward, the shaping plate 21 drives the inner cavity of the hollow plate 23 to slide on the surface of the guide post 24, and at the same time, the third spring 27 is compressed to store energy. Through the setting of the third spring 27, the rebounding force of the third spring 27 continuously pushes the shaping plate 21 to reset, which is convenient for the staff to quickly take the material.

[0031] Working principle: When the staff needs to quickly replace the module body 6, the staff horizontally pulls the pull rod 16, driving the inner cavity of the sliding piece 12 to slide on the surface of the fixed rod 11, and at the same time squeezing the first spring 17 to store energy. As the sliding piece 12 displaces, the surface of the limiting block 14 driven by the sliding piece 12 gradually disengages from the inner cavity of the limiting groove 13. At this time, the staff vertically pulls down the pull rod 16, and at the same time drives the connecting block 9 to slide in the inner cavity of the adjusting housing 7, so that the connecting block 9 squeezes the second spring 20 to store energy. As the connecting block 9 displaces, the connecting block 9 drives the fixed rod 11 to displace, and at the same time drives the surface of the guiding block 19 to slide in the inner cavity of the guiding groove 18. At this time, the sliding piece 12 and the limiting block 14 gradually disengage from the inner cavity of the limiting housing 8. At this time, the module body 6 will be unconstrained, and the module body 6 can be replaced. Through the setting of the above structure, it is convenient for the staff to quickly replace the module body 6, thereby improving the usability of the injection molding machine body 1. When the staff needs to quickly reset the shaping plate 21 and at the same time facilitate discharging, the staff starts the cylinder 4, so that the cylinder 4 pushes the connecting plate 5 and the module body 6 to press down. As the connecting plate 5 displaces, the inner cavity of the guiding plate 26 driven by the connecting plate 5 slides on the surface of the guiding rod 25. As the module body 6 gradually moves down, the module body 6 drives the shaping plate 21 to move down for injection molding. At the same time, the shaping plate 21 drives the inner cavity of the hollow plate 23 to slide on the surface of the guiding column 24, and at the same time squeezes the third spring 27 to store energy. Through the setting of the above structure, when the staff starts the cylinder 4 again, the connecting plate 5 and the module body 6 move up. At this time, the rebounding force of the third spring 27 continuously pushes the shaping plate 21 to move up, facilitating the quick discharging of the shaping plate 21, thereby improving the production efficiency of the injection molding machine body 1.
