By providing the protective device 4, the effect of protecting the discharge port of the injection molding machine body 1 is achieved, and it is prevented that dust adheres to the surface of the discharge port of the injection molding machine body 1, resulting in the product produced by the injection molding machine body 1 sticking to the dust when sliding out of the discharge port of the injection molding machine body 1, resulting in the product being unqualified, thereby improving the practicality of the equipment.

[0032] The specific configuration and functions of the dustproof device 3 and the protective device 4 are described in detail below.

When the staff needs to cover the dustproof plate 34 to When the surface of the feed inlet 2 is reached, the limit rod 37 is pulled, and the limit rod 37 slides in the connecting plate 36. When the limit rod 37 moves to the appropriate position, the dust cover 34 is rotated. When the dust cover 34 covers the surface of the feed inlet 2, the limit rod 37 is located directly in front of the limit groove of the dust cover 34, and the limit rod 37 is pushed. When the limit rod 37 is inserted into the inner surface of the limit groove of the dust cover 34, the limit rod 37 limits the dust cover 34, thereby achieving the effect of fixing the dust cover 34. At the same time, it is also convenient for the staff to quickly close and open the dust cover 34, reducing unnecessary cumbersome steps. The surface of the limit rod 37 is provided with a groove, and the inner surface of the groove of the limit rod 37 is fixedly connected with a handle 38.

When the limit rod 37 moves to the appropriate position, the staff can cover the dustproof plate 34 to the surface of the feed inlet 2 and push the handle 38. The handle 38 drives the limit rod 37 to move until the limit rod 37 is inserted into the inner surface of the limit groove of the dustproof plate 34, thereby facilitating the staff to move the limit rod 37 and avoiding the situation that the surface of the limit rod 37 is too smooth, causing the staff to slip when moving the limit rod 37, thereby causing the staff to be inconvenient to move the limit rod 37. The arc surface of the rotating rod 33 is covered with two torsion springs. 39. The two ends of the torsion spring 39 are fixedly connected to the rotating block 32 and the dustproof plate 34 respectively. When the staff needs to use the injection molding machine body 1, they need to open the dustproof plate 34 first and move the handle 38. The handle 38 drives the limit rod 37 to move. When the limit rod 37 is completely separated from the inner surface of the limit groove of the dustproof plate 34, the limit rod 37 releases the limit on the dustproof plate 34. The torsion force of the torsion spring 39 drives the dustproof plate 34 to rotate. The dustproof plate 34 drives the rotating rod 33 to rotate on the surface of the rotating block 32 until the dustproof plate 34 is fully opened. The torsion force of the torsion spring 39 achieves the effect of automatically opening the dustproof plate 34, while keeping the dustproof plate 34 in an open state, thereby facilitating the staff to deliver materials into the feed port 2.
