What is the most complex mold? Plastic mold or hardware mold

In short, a mold is a tool used to shape objects. This tool is made up of various parts. Different molds are made up of different parts. It is mainly through the change of the physical state of the formed material to achieve the processing of the object shape.
According to the different materials, the mold can be divided into metal mold and non-metal mold. Metal mold is divided into: casting mold (non-ferrous metal die casting, steel casting), and forging mold; non-metallic mold is also divided into: plastic mold and inorganic non-metallic mold. According to the different materials of the mold itself.
Mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic mold is closely related to people's life. Plastic mold can be generally divided into: injection molding mold, extrusion molding mold, gas assisted molding mold and so on.

Generally, the plastic mold consists of two parts: the moving mold and the fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During the injection molding, the movable mold and the fixed mold are closed to form the pouring system and the mold cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products.
Although the structure of the mold may vary greatly due to the variety and performance of the plastic, the shape and structure of the plastic products and the type of the injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature regulating system, forming parts and structural parts. The pouring system and molding parts are the parts which are in direct contact with the plastics and change with the plastics and products. They are the most complex and changeable parts in the plastic mold, which require the highest processing finish and precision.
The pouring system refers to the part of the flow channel before the plastic enters the cavity from the nozzle, including the main flow channel, the cold material hole, the shunt channel and the gate, etc. Forming parts refer to all kinds of parts forming the shape of products, including moving die, fixed die and cavity, core, forming rod and exhaust port.
