Injection moulding of Dustbin Mould is a processing method used in batch production of some parts with complex shapes. The specific principle refers to the heated and melted plastic raw materials are pushed by the screw of the injection moulding machine and injected into the mould cavity of the dustbin mould under high pressure, and the plastic moulded products are obtained after cooling and curing.
The dustbin mould injection moulding consists of a moving mould and a fixed mould, the moving mould is installed on the moving template of the injection moulding machine, and the fixed mould is installed on the fixed template of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a gating system and a mould cavity, and during mould opening, the movable mould and the fixed mould are separated to take out plastic products.
Although the injection moulding structure of the dustbin mould may vary depending on the type and performance of plastic, the shape and structure of plastic products, and the types of injection machines, the basic structure is the same.
The injection moulding structure of the dustbin mould is divided into functions and mainly consists of a gating system, a temperature adjusting system, a moulding part system, an exhaust system, a guide system, an ejection system and the like. Among them, the gating system and moulding parts are the parts that are in direct contact with plastic and change with plastic and products. They are the most complicated and most changeable parts in the dustbin mould, requiring the highest finish and precision.
