Technical Field
The invention belongs to the field of injection molding equipment, and particularly relates to an injection molding machine capable of automatically feeding and discharging materials.
Background
Injection molding machines are also known as injection molding machines or injection molding machines. It is a main forming equipment for making thermoplastic plastics or thermosetting plastics into various shaped plastic products by using plastic forming mould. Some plastics need to be embedded with parts, such as embedded screws, rivets and the like, in the injection molding process, so that the parts are directly fused with the injection molding part, the subsequent assembly time and the subsequent process are saved, and the assembly quality of the parts and the injection molding part is improved. At present, when the injection molding part is produced by injection molding of an injection molding machine, workpieces such as screws, rivets and the like are required to be buried into corresponding positions in a cavity of the injection molding machine manually or through mechanical clamping jaws. Because the workpieces such as screws and rivets are small in size, the workpieces are not convenient to embed by manual operation or clamping and embedding by a mechanical arm, the workpieces are easy to shift or not thoroughly embed, and the quality of injection molding parts is further affected.

The rivet is sucked and fixed through the suction nozzle, and then the rivet is ejected and buried through the air injection of the suction nozzle, so that the rivet can be accurately aligned and mounted at the corresponding position. However, the rivet is adsorbed and fixed only through air suction, so that the suction nozzle and the rivet need to be kept in an air suction state in the whole course in the process of moving from the feeding position to the embedded position, an air source needs to be continuously operated to suck air to the suction nozzle, the energy loss is increased, and the rivet easily falls off from the air nozzle due to mechanical vibration in the moving and conveying process, so that the air nozzle cannot normally feed and feed the rivet.
