1. Two-plate mold: referred to as big nozzle mold, as shown in following figure:
More than 60% of products can meet requirements of two-plate molds.

 

2 Three-plate mold: referred to as fine nozzle mold, as shown in following figure:
In the case of complex product structure and multiple cavities in one mold, three-plate molds are basically used to dispense glue to meet product requirements.

 

3. Two-plate and half-mold: referred to as core-pulling structure of front mold of large nozzle, it can also be called a simplified fine nozzle.
In the case of high product appearance requirements, front mold needs to be core-pulled through tunnel, and a two-plate half mold will be used.

 

4. Open hot runner mold: also known as large nozzle mold hot runner feeding, as shown in following figure:
In the case of a large amount of products, in order to save molding cycle, save nozzle material, and save product price.

 

5. Needle point hot runner mold: referred to as hot runner point injection, as shown in following figure:
When product appearance requirements are high, output is relatively large, needle point type hot runner can be used to save nozzle material, shorten molding cycle and save product price.

 

 

6. Needle valve type hot runner mold: It can also be said to be dispensing glue, as shown in following figure:

 

7. Master mold inversion mold: referred to as master mold ejection mold, as shown in following figure:
When product is relatively large and appearance requirements are high, it can be considered to pour glue backwards. For example, cover of notebook computer uses back glue.

 

 

8. Front mold Huff structure mold, as shown below:
When product is a ring type product, and circumference is inverted, front mold half structure can be considered.

 

9. Secondary ejection structure mold: as shown in the following figure:
When product has a relatively small undercut surface, and undercut surface is only about 0.3~0.6mm, when lifter or the slider is not easy to pull core, a strong release mechanism can be used, and a secondary ejection structure needs to be used.

 

10. Thread core pulling mold structure: as shown in following figure
When product is an internal thread, it is basically necessary to use a thread core-pulling structure.
