Background
An injection molding machine is also known as an injection molding machine or an injection machine. It is a main forming equipment for making various shaped plastic products from thermoplastic plastics or thermosetting plastics by using plastic forming mould. The device is divided into a vertical type, a horizontal type and a full-electric type. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The mold opening is originally a term of mechanical production or process production, and refers to the manufacture of a mold set. The term is now used in industry to refer to the set of tools that form the product design, including the mechanical equipment and the mold. Meanwhile, mold opening is a production process which occupies a high total investment, and production technology, materials and other factors can increase the cost of mold opening, so mold opening is an important production process. The mold opening devices in the current market are generally single-cylinder mold opening, so that the work efficiency is low, the cost is high, and an ejection mechanism needs to be additionally arranged.
