Specific embodiment
As shown in Figure 1, the extruding machine of the utility model plastic molding press, the hopper holding raw material with is connected, and comprises a screw rod 1, machine barrel 2 and agitating unit 3.
Screw rod 1 is installed in machine barrel 2, the axis of screw rod 1 and the dead in line of machine barrel 2.The spiral shell rib 12 that screw rod 1 has a center-pole 11 and arranges around this center-pole 11 spiral.Spiral shell rib 12 has a left surface and a right flank, and spiral shell rib 12 adjacent between two defines screw channel 13.
Machine barrel 2 has the outlet 21 of welding with hopper, and a machine tube inner wall towards screw rod 1.Similar to existing machine barrel, this machine barrel 2 can be roughly divided into solid conveying zone, melting zone, melt Conveying district.At melting zone, the projection of limit in the radial direction of center-pole 11 of spiral shell rib 12 is not a circle, but a shape (as shown in Figure 2) generally in three leaf curves.By the change of spiral shell rib 12 radial thickness, make raw material in the process of melting, the thrust being subject to the face of spiral is change, and the thrust of change like this contributes to making the speed of the raw material diverse location of molten condition different, thus is closing on the effect of center-pole 11 place generation stirring.
Agitating unit 3 comprises and to be fixed on screw rod 1 and cross section is the swingle 31 of fusiformis and is positioned at melting zone and is fixed at machine barrel 2 cross section fin 32 generally triangular in shape.Swingle 31 is vertically installed on center-pole 11, at least arranges a swingle 31 in the middle of two adjacent spiral shell ribs 12.Swingle 31 is higher than spiral shell rib 12, and namely the height of swingle 31 is greater than the height of spiral shell rib 12.In the axial direction, fin 32 is between spiral shell rib 12 and swingle 31.The raw material being positioned at the molten state of screw channel 13 is except in closing on except the thrust that center-pole 11 place changed, also be subject at center-pole 11 and the centre of machine tube inner wall the thrust that cross section is the change of the swingle 31 of fusiformis, be close in the raw material of the molten state of machine tube inner wall, also can be subject to the pushing force of fin 32.Preferably, the axis of the long axis direction of swingle 31 cross section, the longest edge direction of fin 32 and center-pole 11 is perpendicular.Cross section due to swingle 31 is the thick fusiformis in centre pointed at both ends, does not have raw material and is trapped on swingle 31, same, although fin 32 is positioned on the screw channel 13 of screw rod 1, does not also have raw material and is trapped on fin 32.
