A kind of engineering plastics section bar that the utility model provides extrude draw-gear, comprise shaper and hauling machine; In addition, also comprise the traction auxiliary member, described traction auxiliary member is arranged between shaper and the hauling machine, and its front end is connected to hauling machine, and the rear end is positioned at the die cavity of shaper.Use the utility model, the material of molten condition enters the shaper die cavity and wraps the rear end of traction auxiliary member fully, start hauling machine, hauling machine drives the traction auxiliary member and it is moved forward, and then haul extruded product and enter hauling machine as extruding power, thereby enter the ordinary production state with tractive force.
The utility model can be taked following further measure: described traction auxiliary member comprises machine leader and traction seat, and the front portion of described traction seat is connected with hauling machine; The front end of described machine leader is connected the rear end of traction seat, and the material section of drawing at machine leader rear portion is arranged in the die cavity of shaper.
Machine leader described in the utility model can be for more than two or two, and is corresponding with the die cavity of described shaper and be arranged between the rear end and shaper of described traction seat, thereby being applicable to that a mould has more extrudes production technology.For example, corresponding with the die cavity of shaper, between the described machine leader with laterally be arranged side by side and have one row or one row more than.
For ease of the replacing of machine leader, the detachable rear end that is connected traction seat of the front end of described machine leader.Specifically can take following scheme: the rear end of described traction seat is provided with and is vertically and mounting groove corresponding with machine leader and the pin hole that is laterally and crosses with described mounting groove; The front end of described machine leader is provided with installing hole, and described installing hole is positioned at pin hole with the mounting groove that machine leader inserts traction seat, and wears installing hole and the front end of machine leader is connected in the mounting groove and pin hole of traction seat by pin.
The height of traction seat described in the utility model is consistent with the height of extruded product, so that product enters hauling machine smoothly.
The utlity model has following beneficial effect:
(1) the utility model fused materials wraps the material section of drawing of machine leader fully in the shaper die cavity, drive traction seat and then drive machine leader by hauling machine, finally haul extruded product and enter hauling machine, realize adopting tractive force to replace die pressure as extruding power, make that mould keeps the low-pressure state when starting traction, avoided that the prior art high pressure goes out that product brings melt ejection phenomenon, improved the security and the reliability of producing.
(2) have more production technology for a mould, can guarantee the uniformity of each nib pressure and obtain identical extruded velocity, keep the uniformity of tractive force just can guarantee the synchronism of extruded product, effectively improved the stability and the reliability of producing.
(3) save the operating time, reduced labour intensity.Before starting hauling machine, check and adjust the situation of machine leader; After starting hauling machine, only operating host just can directly enter production status, and the assurance all over products can both be extruded smoothly.
(4) machine leader is replaceable, not only is convenient to the part adjustment or changes the damage parts, and can be applicable to the production that other is of the same type flexibly, has saved production cost.
