Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an adjustable injection molding machine. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] When the injection molding machine is in use, the injection molding machine can control the injection molding speed through an electrical control system. However, when feeding the existing injection molding machine, the plastic can often be added all at once and then enter the injection molding machine for melting.
