ASSEMBLY

 

Assembly is a highly skilled operation in which each parts manufactured is fitted into their respective places considering the function.

Each part should be checked for fit or mating relation such as core and cavities, guide bush and pillars etc .


FIXED HALF ASSEMBLY

              After completing all machining operation inspect main cavity and sub cavity insert thoroughly as per drawing .And then check for the assembly designs and part list. Guide pillars (item no10) are fitted in the respective holes with collar system, & Rest pins (item no20) are placed inside the cavity plate (item no04). And then suit the sub cavity insert in main insert than check for fixed half, fit the Cam pin in cavity plate and now suit main cavity insert in cavity plate. fit the wedges in cavity plate and clamp with M8screw on six side .now clamp cavity plate to top plate with M12 screws on four the side,  And Next sprue bush (item no21) is fitted in the front and movement is restricted with the locating ring on the top which in turn is fixed on top plate (item no 18) with the help of M20mm screws.  These are all care should be taken during the assembling of fixed half.           

 MOVABLE HALF ASSEMBLY

Before assembling core side inspect main core ,sub insert, slider, slider insert and guide rail and all spotting area. And than main core insert(item no25)are placed inside the core holder plate housing (item no03)and another core sub insert clamped in the core insert.

 

          After suiting core now suit the guide rail ,since there are two slider two guiderail  are used so two guide rail one on each side is screw to core plate with M10x60mm  and8mm dowel  it. And fit the Ball catchers from back side of core plate in calculated position.              

 

Inserting  return pins and sleeve in respective hole maintain H7g6 fit ejector assembly is completed; the return pin heads are matched with ejector plate surface, the ejector pillars and bushes are fitted, then back plate is fitted to the ejector plate with help of M8X30mm screws. The pillars are oiled and the movement of ejector assembly is checked. The core half is inverted and spacer on the core plate and bottom plate is spaced on the spacers. Then both of them clamped together with M12 screws, And core holder is clamped with bottom plate with screw of M8. The leveled feet buttons are screw to ejector back plate to resist back pressure. After assembly of both halves the mould was closed for blue matchi
