Abstract

An injection moulding apparatus is composed of injection unit consisting of mould and cooling system, mould locking unit and control unit. Said cooling system consists of the cooling medium pipeline in the mould and the heat conductive cooling medium comprising the ultrafluid and the carbon nanotubes separatedly suspended in said ultrafluid.

Description

【Technical field】 [0001] The invention relates to precision molds and precision machinery, in particular to an injection molding device. 【Background technique】 [0002] In recent years, the degree of industrial automation has been increasing day by day, and molds have played a very important role in the field of manufacturing. When molds are used to manufacture products, the molding methods usually include injection molding, compression molding, blow molding, and foam molding. It can form molded products with complex shapes, precise dimensions, and metal or non-metal inserts at one time. Therefore, the method has strong adaptability, high production efficiency, and can produce high-precision three-dimensional parts. [0003] According to the mechanical action of the mold, injection molding can be divided into five stages: clamping stage, filling stage, pressure holding stage, cooling stage and mold opening and ejection. The two stages of holding pressure and cooling are al...
