[0002] Injection molding machine, also known as injection molding machine or injection machine, 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 plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity. Injection molding refers to various injection molding products produced by injection molding machines, collectively referred to as injection molding, including various packages, parts, etc., which are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Injection molding is generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding and thermoforming are to shape plastics on a plane. The above methods can all be used for rubber processing. At present, after the injection molding product of the injection molding machine is formed, the injection molding product is located in the mold cavity. People generally use a device to assist the injection molding product demolding of the injection molding machine to demold the injection molding product located in the mold cavity. However, when the existing device to assist the injection molding product demolding of the injection molding machine is demolded, the temperature inside the mold after injection molding is high, and the time waiting for the mold to cool down is long, which reduces the production efficiency.
