Description

Technical Field

[0001] The utility model relates to the technical field of moulds, in particular to a mould quick replacement device. Background Technique

[0002] A mould is a tool that uses a specific shape to form a blank (solid and liquid) into a workpiece with a certain shape and size under the action of external force. Moulds are extremely widely used in forging, stamping, powder metallurgy pressing, die casting, and the forming processes of compression molding and injection molding of products such as engineering plastics, rubber, and ceramics. Moulds are generally divided into two parts, which are divided into a moving mould and a stationary mould according to the motion state, and into a concave mould and a convex mould according to the shape. There are various types of moulds, such as steel moulds, iron moulds, tin moulds, wooden moulds, gypsum moulds, clay moulds, etc. Among them, the steel moulds are the most used and have the reputation of the "mother of industry". Due to production needs, the moulds on the equipment need to be frequently replaced. For example, for the moulds of stamping equipment, some small-sized moulds are relatively heavy. When handling, workers generally place the moulds on a trolley with rollers for handling.
