Advantages and disadvantages of injection mold two - and three-plate die

Injection mold two plate mold generally refers to the mold in the process of opening the mold is only divided into two halves of the moving mold side and the fixed mold side. Injection mold three plate mold is in the process of opening the mold is not separated, but the first plate and the mother template separate plate will be removed from the material head from the product, and then the male and female mold separate, top out of the product of the mold.

Deformation of two - and three-plate injection molds

The deformation of the two plates of the injection mold, such as adding springboard, controlling the sequence of opening the mold, and realizing the delay of opening the mold of the core pulling mechanism such as the slider. Two plate mold deformation, the product needs to be removed from the mold core; A deformation of the three plate die is combined with the flow channel of the two plate die. Some deformation of the two plate die can also be applied in the three plate die, but the die is relatively complex.

Advantages of two - plate three - plate injection mold

The advantages of injection molding two plate die: two plate die is the most common, its simple structure, diverse forms, convenient maintenance; Two plate mold gate forms include direct feeding, edge gate, latent gate, horn gate, lap gate, disc gate, fan gate, radial gate and so on.

Injection molding three plate mold advantages: two plate mold gate form only point gate; The three - plate mold leaves small gate marks on the product. Can be traceless molding; No additional removal is required for the three die gate.

Disadvantages of two - plate three - plate injection mold

Disadvantages of injection molding two plate mold: two plate mold in addition to the latent and horn gate need to be removed by subsequent processing.

The disadvantages of injection molding three plate die: three plate die flow channel is longer, need longer cooling time, that is, need longer molding cycle; Two plate die consumption material; The three-plate mold is relatively complex in structure.

Application of two - plate and three - plate injection mold

Application of two plate die: the appearance of the surface requirements are not very strict, large water mouth workpiece is suitable for two plate die; The application of three plate die: the appearance of high surface requirements, generally used gate is: point gate and latent gate.
