1) Assembly of inserts 11, 16 and fixed mold 17
Put the insert 16 and the core 15 into the fixed mold first, and measure the actual size of the two protruding surfaces. Exit the fixed mold, according to the actual size of the core 9 height and the fixed mold depth, separately grind the core and inserts, and then install the fixed mold, check the insert 16, core 15 and core 9, see Whether the fixed mold and the discharge plate are in contact at the same time. Insert the core 12 into the insert 11 and position it with pin holes. Pre-grind the bevel of the core based on the shape of the insert and the bevel. Put the pre-ground cores and inserts into the fixed mold, close the fixed mold and the unloading plate, measure the gap size of the parting surface, and then withdraw the insert 11, according to the measured gap size. Grind the bevel of the core to the required size. After inserting the insert 11 into the fixed mold, the supporting surface of the fixed mold is smoothed.
2) Assembly of mold and fixed mold base plate
Before assembling the fixed mold and the fixed mold seat plate, the sprue sleeve and the fixed mold seat plate have been assembled qualified. Therefore, the fixed mold and the fixed mold seat plate can be directly superimposed, and after the sprue hole on the sprue sleeve is aligned with the sprue hole on the fixed mold, the fixed mold and the fixed mold seat plate can be clamped by a parallel chuck , Drill cones, drill and dumpling pin holes on the fixed mold through the fixed mold seat plate hole. Then disassemble the two, drill holes and tap threads on the fixed mold. Then superimpose the fixed mold and the fixed mold seat plate, install the pins and tighten the screws.
