    塑料模具的分类有哪些?

    按照成型方法的不同,可以划分出对应不同工艺要求的塑料加工模具类型,主要有注射成型模具、挤出成型模具、吸塑成型模具、高发泡聚苯乙烯成型模具等。
    According to the different molding methods, we can divide different types of plastic processing mould corresponding to different process requirements, mainly including injection mould, extrusion mould, plastic suction mould, high foaming polystyrene mould and so on.
    1、塑料注射(塑)模具主要是热塑性塑料件产品生产中应用为普遍的一种成型模具,塑料注射模具对应的加工设备是塑料注射成型机,其结构通常由成型部件、浇注系统、导向部件、推出机构、调温系统、排气系统、支撑部件等部分组成。
    1, the plastic injection mold (plastic) is thermoplastic plastic products the most universal of a mold used in the production of processing equipment, plastic injection mold is the corresponding plastic injection molding machine, the structure is usuallyforming parts casting direction components introduced institutions regulated system exhaust system support component parts.
    2、塑料压塑模具。包括压缩成型和压注成型两种结构模具类型。压注成型与压缩成型不同的是有单独的加料室,成型前模具先闭合,塑料在加料室内完成预热呈粘流态,在压力作用下调整挤入模具型腔,硬化成型。压注模具广泛用于封装电器元件方面。压塑模具制造所用材质与注射模具基本相同。
    2, plastic plastic mould. It includes two kinds of die types: compression molding and pressure injection molding. The difference between pressure injection molding and compression molding is that there is a separate feeding chamber. Before forming, the mold is closed first, and the plastic is preheated and visiform in the feed room. Under pressure, it is adjusted into the mold cavity and hardened. The injection mold is widely used in the packaging of electrical components. The material used for the manufacture of the plastic mould is basically the same as the injection mold.
    3、塑料挤出模具是用来成型生产连续形状的塑料产品的一类模具,又叫挤出成型机头,广泛用于管材、棒材、单丝、板材、薄膜、电线电缆包覆层、异型材等的加工。与其对应的生产设备是塑料挤出机,其原理是固态塑料在加热和挤出机的螺杆旋转加压条件下熔融,塑化,通过特定形状的口模而制成截面与口模形状相同的连续塑料制品。

    3, plastic extrusion molds are used for molding and manufacturing continuous moulds of plastic products. They are also called extrusion die heads. They are widely used for processing pipes, bars, monofilament, plates, films, wires and cables, cladding, profiled materials and so on. Its corresponding production equipment is a plastic extruder. Its principle is that solid plastic is melted and plasticized under the condition of heating and extruder screw rotation and pressure, and the continuous plastic product with the same shape with the same die is made through the special shape die.

    4、塑料吹塑模具是用来成型塑料容器类中空制品(如饮料瓶、日化用品等各种包装容器)的一种模具,吹塑成型的形式按工艺原理主要有挤出吹塑中空成型、注射吹塑中空成型、注射延伸吹塑中空成型(俗称"注拉吹"),多层吹塑中空成型,片材吹塑中空成型等。中空制品吹塑成型所对应的设备通常称为塑料吹塑成型机,吹塑成型只适用于热塑料品种制品的生产。吹塑模具结构较为简单,所用材料多以碳素多则制造。
    4, plastic blow molding is used for molding plastic containerslike hollow products (such as beverage bottles, cosmetic supplies all kinds of packaging containers) of a mold molding process in the form of the main principle of extrusion blow molding, injection blow molding, injection stretch blow molding (commonly known as "injection blowing"), multi-layer blow hollow molding, sheet blow molding etc/ The equipment corresponding to the blow molding of hollow products is usually called plastic blow molding machine, and the blow molding is only suitable for the production of hot plastic products. The blow molding die structure is relatively simple, and the material used is made with more carbon.
