1.Structural of 2 plate mold

Two plate mold core assembly

Two plate mold core inside the core
graft transplantation


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.
 The structure of the mold: simple structure
consisting of 2 main parts core and cavity.

 Products after withdrawing mold: products
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
