A plastic mold is a tool which is matched with a plastic molding machine in the plastic processing industry and gives a complete configuration and accurate dimension to a plastic product. Because of the variety and processing method of plastic, and the structure of plastic molding machines and plastic products are various, the variety and structure of plastic molds are also various. With the rapid development of the plastic industry and the continuous improvement of general and engineering plastics in the aspects of strength and the like, the application range of plastic products is also continuously expanded, and the consumption of plastic products is also rising.

A plastic mold is a tool for producing plastic articles. It is made up of several sets of parts, and the combination has a moulding cavity. During injection molding, a mold is clamped on an injection molding machine, molten plastic is injected into a forming mold cavity and is cooled and shaped in the cavity, then an upper mold and a lower mold are separated, a product is ejected out of the mold cavity through an ejection system and leaves the mold, finally the mold is closed again for next injection molding, and the whole injection molding process is carried out in a circulating mode. Generally, a plastic mold is composed of a movable mold and a fixed mold, the movable mold is mounted on a movable mold plate of an injection molding machine, and the fixed mold is mounted on a fixed mold plate of the injection molding machine. And when the mold is opened, the movable mold is separated from the fixed mold so as to take out the plastic product.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
