High Precision HSS Syringe Mold Core Tin Coated For Laboratory Pipette Tip Injection Molding Components

Application Description:

The mold core retainer plate is made of alloy mold steel, but may be left soft to avoid possibility of distortion in hardening.
Water lines (detail lit are drilled, and the inlet and outlet are tapped for pipe fittings. the mold core plate is tapped for 8 retainer screws
The guide pin bushings are mounted in this plate.
They are hardened and ground, with a retaining shoulder at the back.
The mold core retainer plate is ground to the same thickness as the cavity blocks, and then a relief is turned outside that area required for closing off the runners and landing the ejector return pins
The land which is left is as small in area as possible to increase the unit pressure holding the mold closed.
The alloy steel plate, though unhardened, is tough enough to withstand some battering and crushing as the mold closes.
A hole is bored in the mold core retainer plate center to receive the sprue bushing. plate, and the hole for the cold slug and sprue ejector pin is bored in the center of the plate.
This hole is undercut slightly to hold the cold slug in place until the mold opens, and thus pulls out the sprue slug.
The mold core retainer plate is made of alloy mold steel and left soft as is its mating plate. it is also drilled for water lines in the same relative position.
It is tapped for 4 retainer screws, which hold it to the backing plate.
Clearance holes are provided for three ejector return pins.
The ejector pins are fitted for a short distance back from the molding edge of the plate, and then the holes are opened a little to make clearance and to make the lapping easier.
The three guide pins are mounted in this plate. they are hardened and ground, with a retaining shoulder at the back.
Six runners are cut in the core retainer is just that the first material to enter the mold.
It is liable to be too cold to flow or weld properly, so it is allowed to bypass into the space provided, and the hotter material following is in better condition to mold.
The same relief is provided on the mold core retainer plate as on the mating plate.
It is also ground to the proper height.
The two retainer plates are bored together in order to assure proper alignment of cavities and cores.
Holes for the guide pin bushings are also bored while the plates are clamped together.
