，关于模具零件的英文介绍
Mould parts refer to various components of the mould that make it up, such as a cavity, punch, plunger, guide pins, guide sleeves, dies, punches, templates, precision plate, needle plate, and so on. All these components are vital to the performance of molds and their quality plays an important role in the production of precision parts.
The cavity is the most important part of the mold, which determines the shape of the product. In plastics moulds, polymeric materials such as polystyrene, PVC, polyvinyl chloride, polyethylene, polypropylene and acrylics are used to create the mold cavities. These materials are usually selected according to the production requirements. Moreover, other materials like stainless steel, aluminum, bronze and brass are also used to make the cavity.
The plunger is used to force the molten material into the mould cavity for forming the product. The plunger is usually made of steel and is guided by the guide pins and guide sleeves to control the injection molding process within the mould.
Punches are the cutting blades used to cut materials within the mould. They are made of various materials such as tungsten carbide, high speed steel and plastics. The way the punches cut the material is determined by the shape, size, and motion of the punches.
Guide pins, guide sleeves and precision plate are used to provide accurate position and orientation for the parts entering the mould. The guide pins and guide sleeves provide support to the mould parts and allow them to move freely inside the mould. The precision plate is usually made of steel and is used to separate two plastic parts while they are inside the mould.
Dies are tools used to shape plastic, rubber or metal parts. They are usually made of steel, aluminum or stainless steel. The dies are designed to provide a desired shape and form to the part when it is inserted into the mould.
Needle plates are used to increase accuracy when drilling and pinning plastic parts. They are usually made of stainless steel and are usually attached to the mould base. The needle plates help prevent the plastic from melting when it is heated in order to form the desired shape.
Templates are used to create complex shapes when producing plastic parts. They are made of various materials, like tungsten carbide, plastics or high-density plastic. The templates are inserted into the mould to form the desired shape of the product and are then removed after the product is formed.
These are the main components and tools that make up a mould. Each part plays an important role in providing the best quality parts to customers. In order to produce quality parts, the mould must be well maintained and the components must be replaced if they are damaged or worn out.
