The invention discloses a device for producing a polystyrene pipeline. The device comprises an injection head and an injection molding material tank arranged below the injection head. The bottom of the injection head is provided with a pressure injection plate. The bottom of the injection molding material tank is provided with a discharging opening. The discharging opening is installed on a base. The inner diameter of the injection molding material tank is phi (m). The wall thickness of the injection molding material tank is A (m). The diameter of the pressure injection plate is from phi+A*0.5/100 to phi+A*1/100. Because the fit dimensions between the injection head and the injection molding material tank are improved, the seal performance can be improved, and the work performance is safer and more reliable. 本发明公开了种用于生产聚苯乙烯(PS)管道的设备,包括注射头及其下方的注塑料缸，所述注射头底部安装压力注射板，所述注塑料缸底部设置出料嘴并安装在底座上，所述注塑料缸的内径为φ（m），壁厚为A（m），所述压力注射板的直径为φ+A*0.5/100～φ+A*1/100。本发明对注射头和注塑料缸之间的配合尺寸进行了改进，密封性能得到提高，工作性能也更加安全可靠。
