DETAILED DESCRIPTION
[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0023] like Figure 1 It is a structural schematic diagram of the utility model, a safety door for an injection molding machine, comprising an injection molding machine frame 1, a sliding mechanism 2, a locking mechanism 3, a safety door body 4 and a crossbeam 5. The safety door body 4 is slidably connected to the injection molding machine frame 1, and the crossbeam 5 is slidably connected to the injection molding machine frame 1. By adding a movable crossbeam above the safety door body 1, it has a larger moving space when changing the mold. At other times, the crossbeam can provide support and guidance for the safety door body 1, thereby making the movement of the safety door body 1 more stable and increasing the service life of the safety door body 1.
[0024] The cross beam 5 and the frame 1 of the injection molding machine are slidably connected via a sliding mechanism 2 , and the cross beam 5 is located above the safety door body 4 .
[0025] like Figure 3 , Figure 4 , Figure 6 As shown, the sliding mechanism 2 includes two slide rails 21 and two pulleys 22. The slide rails 21 and the pulleys 22 correspond to each other one by one. The slide rails 21 are fixedly connected to the injection molding machine frame 1, and the two slide rails 21 are arranged at intervals. The pulleys 22 are arranged on the cross beam 5, and the pulleys 22 are in rolling contact with the corresponding slide rails 21. The sliding connection between the cross beam 5 and the injection molding machine frame 1 is realized through the structure of the slide rails 21 and the pulleys 22.
[0026] The pulley 22 is arranged between the two slide rails 21 , and the two pulleys 22 are arranged up and down, and can contact the two slide rails 21 respectively to play a limiting role so that the movement of the crossbeam 5 is stable.
[0027] In another embodiment, the sliding mechanism 2 may be a sliding mechanism composed of a slider and a slide rail, which is not specifically limited in the present application.
[0028] like Figure 7As shown, the injection molding machine safety door also includes a guide mechanism 6, which includes a guide rail 61 and a plurality of guide assemblies 62. The guide rail 61 is fixedly connected to the injection molding machine frame 1, and the guide assembly 62 includes a connecting frame 621 and two spaced guide wheels 622. The guide wheels 622 are arranged on the injection molding machine frame 1 through the connecting frame 621, one of the guide wheels 622 is in rolling contact with the guide rail 61, and the other guide wheel 622 is in rolling contact with the cross beam 5. The guide rail 61 and the cross beam 5 are arranged between the two guide wheels 622, and the two guide wheels 622 clamp the cross beam 5 and the guide rail 61 to play a limiting role, thereby further improving the stability of the cross beam 5 and avoiding its shaking.
[0029] like Figure 1 , Figure 2 As shown, the locking mechanism 3 is arranged on the frame 1 of the injection molding machine, and the locking mechanism 3 is used to lock the crossbeam 5. The locking mechanism 3 includes a lock body 31 and a lock buckle 32 matched with the lock body 31. The lock body 31 is fixedly connected to the crossbeam 5, and the lock buckle 32 is fixedly connected to the frame 1 of the injection molding machine.
[0030] When the cross beam 5 and the frame 1 of the injection molding machine are fixed, the lock body 31 is embedded in the lock buckle 32, thereby preventing the cross beam 5 from being opened due to the vibration during the operation of the injection molding machine.
[0031] The buckle groove of the lock buckle 32 has a bottleneck-shaped port to achieve interlocking locking, which is convenient for locking and releasing, and can improve the convenience of use.
