2 PLATE MOLDS CONSISTING OF TWO MAIN

PARTS:

Cavity

Core

1.STRUCTURAL

2 FEATURE 2 PLATE MOLD

 Two plate mold 1 cavity don't need design runner.

 Two plate mold 1 cavity need design runner and nozzle.

 Nozzle must line up with the cavity.

2.FEATURE 2 PLATE MOLD

• Tables machine motion from left to right to bring core

side.

• Guide pin and guide bush will guide the second half core

and cavity mold.

• When core side docking cavity at parting surface,

molding machine will pump plastic into the cavity.

Cooling system will operate

The process of push compression push

plate springs of the mold

This procedure is performed

continually

 These products have short life cycles, time design and manufacturing short.

 These products have fewer nozzle.

 Products civil, personal items, household appliances.

 The precision products, high technical requirements.

 Runner layout: Set on a horizontal surface with a parting surface.

consisting of 2 main parts core and cavity.

and runner can be separated or not to take the product.

Simple, short molding cycles.

Simple design.

The machining time, making short Cheap

For details have low accuracy.

Automation low.

Costly raw materials

Not be detailed machining complex
