7 7c / 8 " T-Series (3-Plate) Mold Bases
A typical 3-plate top runner mold operates as follows: The mold opens first at Parting Line 1 (spring loaded). The runner and cavity sprues are pulled from the cavities in the X-2-Plate and held against the X-1-Plate by undercut puller pins. As the mold continues to open (X-2-Plate moving forward), stripper bolts SB-1 pull the X-1-Plate forward (at the end of the X-2-Plate movement). The X-1-Plate travel is determined by stripper bolts SB-2. The travel of the X-1-Plate (breaking at Parting Line 2) strips the entire runner system from the puller pins, breaks the main sprue (held to a minimum length), and allows the runner to drop free. Mold opening at Parting Line 3 then takes place for piece-part ejection.

NOTE: Stripper bolts, puller pins and spring shown are not included. When gating directly into the cavity from a top runner, the 3-plate T-Series assembly may be used. It incorporates an additional runner stripper plate (X-1) to facilitate automatic removal of the runner from the mold. The X-1 and X-2-Plates have standard shoulder bushings and ride on standard leader pins. (When heavy X-2- Plates are required, moldmaker may want to specify larger diameter leader pins and have them relocated. Contact customer service for a quotation to your specifications). The X-1-Plate is supplied without a center hole. A standard sprue bushing long enough to extend through the X-1-late is provided to allow the moldmaker to finish the sprue bushing hole as desired, or to install a recessed bushing to give the shortest main sprue length for minimum stripper plate movement. Detailed dimensions for the T-Series are identical to corresponding size A-Series Mold Bases. Center sprue puller pin and pin holes as well as the socket head cap screws in the A- Clamping Plate are omitted since the are not required.
