  The structure and composition of injection mold

  1, forming parts

  Parts that give the shape, structure, and size of the forming material are usually made of a core (punch), a concave mold cavity, and a threaded core, insert, and the like.

  2, pouring system

  It is the channel through which the molten plastic is directed from the injection nozzle to the closed mold cavity,injection mold usually consisting of the main flow path, the manifold, the gate and the cold material well.

  3, guide parts

  In order to ensure that the dynamic mode and the mold is closed when the precise alignment can be set to guide the components,injection mold from the guide positioning, it is composed of the guide column and guide sleeve, and some mold is also set on the top plate guide parts, to ensure that The stripping mechanism moves smoothly and reliably.

  4, stripping mechanism

  To achieve plastic parts and gating system stripping device, its structure in many forms, the most commonly used with mandrel, jacking, roof and pneumatic ejector and other stripping mechanism, generally by the mandrel, reset lever, slingshot, , Roof (top ring) and the roof guide column / guide sleeve and other components.

  5, core pulling mechanism

  For a plastic with a side hole or side concave, it is necessary to perform a side-pulling or separate slider (side-by-side) before being ejected.

  6, mold temperature adjustment system

  In order to meet the mold temperature requirements of the injection molding process, the need for mold temperature adjustment system (such as: cooling water,injection mold hot water, hot oil and electric heating system, etc.) to adjust the temperature of the device.

  7, exhaust system

  In order to smooth the gas in the mold cavity, often in the mold parting surface to open the exhaust slot, many mold putters or other moving parts (such as: slider) between the gap can also play an exhaust role.

  8, other structural parts

  (Such as: fixed plate, moving / set template,injection mold support head, support plate and connecting screws, etc.) to meet the requirements of the mold structure.
