Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a feeding device for an injection molding machine according to an embodiment of the present invention. As shown in fig. 1, the feeding device for an injection molding machine in the embodiment is arranged at a side portion of a feeding port 14 of the injection molding machine, and includes a frame 1, a feeding mechanism, and a horizontal driving mechanism.

Fig. 2 is a schematic structural view of a feeding mechanism in an embodiment of the present invention; fig. 3 is a sectional view of a feeding mechanism in an embodiment of the present invention.

As shown in fig. 2 and 3, the feeding mechanism includes a support base, a magazine unit, and a pouring drive portion.

The supporting seat comprises a supporting plate 2 and a supporting block 3 fixedly arranged on the supporting plate 2. The supporting plate 2 is slidably mounted on the frame 1.
