Injection mould mainly comprises a movable mould and the fixed mould of two parts. Dynamic simulation is active, it is installed on a fixed injection molding machine, so it is not moving. The injection machine, dynamic model will tend to die, they closed form cavity and gating system. When the mould is opened, the moving mold and the fixed mold separation, ejector start action, top out of plastic parts mold, injection molding products to make smooth demoulding. To complete a cycle of work.Although many kinds of injection mold, mold composition but different structures are basically the same. The multi cavity single parting surface of injection mould as an example to illustrate the structure.
  1.forming parts, which is composed of the mold cavity parts, mainly used to determine the shape and size of plastic parts, such as mold plastic parts in the decision, and the die determines the shape of plastic parts.
  2.the gating system, this is the plastic melt is injected into the closed mold cavity channel, has an important effect on the melt flow properties of mould filling and injection molding quality.
  3.Die oriented institutions, mainly used to ensure that the movable mould and the fixed mould, among other parts or tooling to ensure accurate involution, plastic parts shape and size accuracy, and to avoid the various parts of mold in the collision and interference.
  4.temperature control system, because the plastic properties of different requirements of the mold temperature, injection time are also different, therefore, need the temperature on the die temperature control system of regulation. Mould cooling generally rely on cooling water cooling water channel in the mold opening, mold heating depends on the heating element in the die.
  5.The release mechanism, the discharge is completed by the demoulding mechanism.
  6.The parting and core pulling mechanism, when the plastic parts with side concave or side holes, in the mold plastic parts must be put before the launch, forming concave side or side hole of the valve matched module or lateral cores from the plastic parts from, and lateral type or side core pulling mechanism is to realize the functions and settings a lateral movement mechanism.
  7.The supporting parts, these parts are used for installing and fixing or support of molding parts, bearing components assembled together, which constitutes the basic framework of injection mold.
  8.exhaust structure, when the molten material into mould cavity, cavity air needs to be discharged, while the high temperature plastic will be volatile gases, these gases are the need for timely discharge quickly, in order to avoid forming defects, injection molding to discharge these gas exhaust structure of every kind of design.
