[0034] like Figures 1-5 As shown, an anti-slip protection device for an injection station 21 includes: a base 1, an injection assembly 2, and a safety assembly 3.
[0035] The base 1 is provided with a receiving cavity 11.
[0036] The injection assembly 2 includes an injection seat 21 and an injection guide rod 22. The injection seat 21 and the injection guide rod 22 are slidably connected. The injection assembly 2 is housed in the receiving cavity 11. The injection guide rod 22 is connected to the base 1. The injection seat 21 can be raised and lowered relative to the base 1 via the injection guide rod 22.
[0037] The safety component 3 includes a safety rod 31 and a stop block 32. The safety rod 31 is connected to the base 1, and the stop block 32 is rotatably disposed on the injection seat 21. The safety rod 31 is provided with a contact surface 311, and one end of the stop block 32 can contact the contact surface 311.
[0038] Specifically, the injection seat 21 is raised and lowered relative to the base 1 by the injection guide rod 22 to perform injection work. After the injection seat 21 rises to the preset height, the stop block 32 on the injection seat 21 rotates and contacts the contact plane 311 of the safety rod 31, thereby fixing the height of the injection seat 21 and preventing it from falling.
[0039] In this embodiment, since the stop 32 on the injection seat 21 contacts the contact plane 311 of the safety bar 31, the position of the injection seat 21 is effectively fixed by physical blocking, avoiding falling due to gravity or other external forces. As an additional safety guarantee, its simple structure provides users with a safer operating environment.
[0040] like Figures 1-5 As shown, based on the above embodiment, it also includes an elastic element (not shown in the figure). The two ends of the stop 32 are respectively set as a first contact end 321 and a second contact end 322. One end of the elastic element contacts the injection seat 21, and the other end of the elastic element contacts the first contact end 321. The second contact end 322 can contact the safety bar 31.
[0041] In this embodiment, the elastic element pushes the first contact end 321 to move, thereby driving the second contact end 322 to move towards the safety bar 31, so that the stop block 32 can always be close to the position of the safety bar 31. When the injection seat 21 falls due to an accident, the elastic element can push the stop block 32 to rotate in time, thereby achieving a timely braking effect.
[0042] like Figures 1-5 As shown, based on the above embodiment, the bumper 31 is also provided with a contact slope 312, the contact plane 311 is connected to the contact slope 312, and the second contact end 322 can contact the contact slope 312 and the contact plane 311.
[0043] Specifically, under the action of the elastic element, the second contact end 322 of the stop block 32 always moves closer to the safety bar 31. When the injection seat 21 moves, the second contact end 322 will contact the contact slope 312, thereby pushing the stop block 32 to rotate until the second contact end 322 separates from the contact slope 312. At this time, the second contact end 322 will continue to move closer to the safety bar 31 under the action of the elastic element and contact the next contact plane 311.
[0044] In the embodiment, due to the effect of the contact slope 312, the injection seat 21 is not blocked by the bumper 31 during the rising process, and the height of the injection seat 21 is fixed due to the effect of the elastic member and the contact plane 311 during the falling process, so that the smooth rising of the injection seat 21 is ensured, and the safety accidents caused by falling are prevented.
[0045] As shown in the above embodiment, the number of the contact slope 312 and the contact plane 311 is at least two, and the contact slope 312 and the contact plane 311 are sequentially and crossly connected. Figures 1-5
[0046] In the embodiment, due to the fact that the number of the contact slope 312 and the contact plane 311 is at least two, the injection seat 21 can be braked at different heights at any time to prevent falling, and the flexibility and safety of the device are improved.
[0047] As shown in the above embodiment, the number of the contact slope 312 and the contact plane 311 is at least two, and the contact slope 312 and the contact plane 311 are sequentially and crossly connected. Figures 1-5 In the embodiment, the elastic member pushes the stop block 32 to rotate through the ejector pin 4, so that the contact area between the elastic member and the stop block 32 is larger, and the transmission is more stable during the back-and-forth rotation of the stop block 32.
[0048] As shown in the above embodiment, the number of the contact slope 312 and the contact plane 311 is at least two, and the contact slope 312 and the contact plane 311 are sequentially and crossly connected.
[0049] Figures 1-5 As shown in the above embodiment, the number of the contact slope 312 and the contact plane 311 is at least two, and the contact slope 312 and the contact plane 311 are sequentially and crossly connected.
[0050] In the embodiment, the elastic member and the ejector pin 4 are arranged on the injection seat 21 through the spring mounting plate 5, which means that they can be conveniently installed or removed from the injection seat 21, providing great convenience for maintenance and replacement. A special spring accommodating groove is arranged on the spring mounting plate 5, and the ejector pin 4 can freely slide in the spring accommodating groove, so that the ejector pin 4 can move along the predetermined path under the action of external force, ensuring its stability during long-term work.
[0051] As shown in the above embodiment, the number of the contact slope 312 and the contact plane 311 is at least two, and the contact slope 312 and the contact plane 311 are sequentially and crossly connected. Figures 1-5 As shown, based on the above embodiment, the end of the ejector pin 4 away from the elastic member is provided with a hemispherical surface 41, and the ejector pin 4 can contact the stop block 32 through the hemispherical surface 41.
[0052] In this embodiment, the first contact end 321 of the stop block 32 contacts the hemispherical surface 41 during rotation. Due to the presence of the hemispherical surface 41, the first contact end 321 of the stop block 32 can gradually and evenly apply pressure to the elastic element while rotating, thus optimizing the force transmission path and ensuring a more uniform force distribution, thereby avoiding potential damage to the elastic element caused by local stress concentration.
[0053] like Figures 1-5 As shown, based on the above embodiment, it also includes a striker 6 and a protective door 7. The striker 6 is connected to the first contact end 321, and one side of the protective door 7 is rotatably connected to the base 1. The protective door 7 can contact the striker 6 during opening and closing.
[0054] Specifically, during the closing process, the protective door 7 pushes the stop 32 to rotate through the impact rod 6, causing the second contact end 322 to separate from the safety rod 31, thereby realizing the free up and down movement of the injection seat 21. When it is necessary to operate inside the injection seat 21, the protective door 7 needs to be opened. At this time, the protective door 7 separates from the impact rod 6, and the stop 32 moves closer to the safety rod 31 again under the action of the elastic element, thereby fixing the height of the injection seat 21.
[0055] In this embodiment, the design of the protective door 7 and the impact bar 6 prevents the height of the injection seat 21 from being adjusted arbitrarily without closing the protective door 7, effectively avoiding the safety accident caused by the injection seat 21 falling due to an accident.
[0056] like Figures 1-5 As shown, based on the above embodiment, the injection seat 21 is further provided with a guide hole 211, and the safety rod 31 is accommodated in the guide hole 211. The injection seat 21 can be vertically connected to the safety rod 31 through the guide hole 211.
[0057] In this embodiment, the guide hole 211 on the injection seat 21 ensures that the relative position of the safety rod 31 and the injection seat 21 is fixed. When the height of the injection seat 21 is fixed, if the injection seat 21 falls accidentally, the impact between the safety rod 31 and the stop block 32 can ensure that the safety rod 31 is always contained in the guide hole 211, preventing it from shifting, and further improving the safety and reliability of the anti-slip protection device for the injection seat 21.
[0058] like Figures 1-5As shown, on the basis of the above-mentioned embodiment, further comprising a driving element 8 connected with the injection guide rod 22, the output shaft of the driving element 8 is connected with the injection seat 21, and the driving element 8 can drive the injection seat 21 to ascend and descend relative to the injection guide rod 22.
[0059] In the present embodiment, the driving element 8 provides power support for the injection seat 21, enabling it to move smoothly up and down along the injection guide column, ensuring high precision and repeatability of the injection process, greatly improving the operation efficiency and accuracy.
