VALVE GATE TYPE MOLD ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To facilitate the alignment of a valve pin and a gate. SOLUTION: A valve casing 12 is equipped with the gate 14 formed to the leading end of the casing, a valve pin support hole 27 formed on the side of the gate 14 to support the valve pin 25 in a freely slidable manner and a guide bush 22 provided on the side of the base end of the casing to support the valve pin 25 in a freely slidable manner. The valve pin 25 is guided and supported by the guide bush 22 provided to the valve casing 12 and the valve pin support hole 27 to open and closed the gate 14 provided to the leading end of the valve casing 12. Therefore, the concentric state of the valve pin 25 with the gate 14 can be obtained only by aligning the valve casing 12 and the valve pin 25.
