Abstract
The utility model discloses a plastic lead rail die of a curtain. The plastic lead rail die of the curtain comprises an injection molding machine feed barrel and a front template with a cavity, wherein a heating device is arranged at the outer wall of the injection molding machine feed barrel; a worm and an inner cavity for containing plastic particles are arranged inside the injection molding machine feed barrel; the front template is detachably connected with the outer end face of the injection molding machine feed barrel; the cavity on the front template is communicated with the inner cavity of the injection molding machine feed barrel; a plurality of positioning rods with threads are arranged on the injection molding machine feed barrel; a plurality of positioning grooves which are matched with the positioning rods and respectively provided with an opened edge are arranged in the front template; the front template is connected with the outer end face of the injection molding machine feed barrel through a lock nut on each positioning rod; a plurality of positioning bumps are arranged on the outer end face of the injection molding machine feed barrel; and a plurality of positioning notches matched with the positioning bumps are arranged in the inner end face of the front template. According to the plastic lead rail die of the curtain, positioning accuracy between the front template and the injection molding machine feed barrel is high, and the front template is convenient to dismantle and mount.
Description
Technical field
The utility model relates to curtain plastic guide rail production equipment technical field, specifically be a kind of curtain plastic guide rail mould.
Background technology
The curtain plastic guide rail generally adopts the plastics extrusion die extrusion molding.At present, all adopt threaded backstay location between the barrel discharging opening for the production of the front template of the curtain plastic guide rail mould of curtain plastic guide rail and injection machine, be that barrel is provided with a plurality of backstays, front template is provided with a plurality of locating holes that coordinate with backstay, by backstay, with locating hole, coordinate front template and barrel location, and make front template and barrel locking by the locking nut on backstay, be provided with the guide rail die cavity in this front template, this guide rail die cavity communicates with the barrel inner chamber.When the curtain plastic guide rail is produced, at first plastic grain that will be to be melted is put into barrel, heater on the barrel outer wall is heated barrel, thereby make the plastic grain fusing in barrel, then the worm screw of barrel the inner is pushed the plastics after melting under the driving of hydraulic cylinder, guide rail die cavity on plastic warp front template after fusing is outwards extruded, thereby forms the plastic guide rail of moulding.Between the front template of this curtain plastic guide rail mould and the barrel discharging opening of injection machine, positioning precision is not high, and replaceability is bad, and particularly, in the process of front template handling, the locating hole on backstay and front template can cause wearing and tearing, causes positioning precision to descend; Moreover the plastics of molten state under high pressure can outwards overflow along the junction of front template and barrel discharging opening, thereby enter in the locating hole of front template, cause when changing front template, need the very large power of expense just can take off front template, it is very inconvenient to change.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, provides between a kind of front template and injecting machine material tube positioning precision high, and the curtain plastic guide rail mould of front template easy accessibility.
Technical solution of the present utility model is, a kind of curtain plastic guide rail mould with following structure is provided: it comprises injecting machine material tube and with the front template of die cavity, described injecting machine material tube outer wall is provided with heater, be provided with the inner chamber of worm screw and accommodating plastic grain in injecting machine material tube, described front template is connected with the outer face of injecting machine material tube is removable, and the die cavity on front template and the intracavity inter-connection of injecting machine material tube, described injecting machine material tube is provided with a plurality of threaded backstays, front template is provided with a plurality of locating slots that match with backstay and all have a unlimited limit, described front template is connected with the injecting machine material tube outer face by the locking nut on backstay, described injecting machine material tube outer face is provided with a plurality of positioning convex, and the inner face of described front template is provided with a plurality of detents that match with positioning convex.
After adopting above structure, the utility model curtain plastic guide rail mould compared with prior art, have the following advantages: this curtain plastic guide rail mould is when installing front template, at first make the backstay on injecting machine material tube pass the locating slot on front template, and a plurality of positioning convex on the injecting machine material tube outer face are engaged in the detent on the front template inner face, then with locking nut, front template are fixed on the injecting machine material tube outer face; Because a plurality of positioning convex on the injecting machine material tube outer face coordinate with the detent on the injecting machine material tube outer face, in the process of front template handling, even the locating slot on backstay and front template can cause wearing and tearing, also can not affect the assembly precision of front template, so between front template and injecting machine material tube outer face, positioning precision is high; Moreover, even the plastics that outwards overflow the junction of front template and injecting machine material tube drop in the locating slot of front template, when front template is dismantled, backing out locking nut, just can easily front template be taken off, dismantle more convenient.
As preferably, in described front template, the cross section of die cavity is " work " font.
As preferably, described backstay is fixedly connected with injecting machine material tube by alignment pin.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model curtain plastic guide rail mould.
Fig. 2 is the structural representation of the front template of the utility model curtain plastic guide rail mould.
As shown in the figure:
1, injecting machine material tube, 2, front template, 3, backstay, 4, locating slot, 5, locking nut, 6, inner chamber, 7, alignment pin, 8, heater, 9, worm screw, 10, detent, 11, positioning convex, 12, die cavity.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2;
It comprises injecting machine material tube 1 and with the front template 2 of die cavity 12 the utility model, described injecting machine material tube 1 outer wall is provided with heater 8, be provided with the inner chamber 6 of worm screw 9 and accommodating plastic grain in injecting machine material tube 1, described front template 2 is connected with the outer face of injecting machine material tube 1 is removable, and the die cavity on front template 2 12 is connected with the inner chamber 6 of injecting machine material tube 1, described injecting machine material tube 1 is provided with a plurality of threaded backstays 3, front template 2 is provided with a plurality of locating slots 4 that match with backstay 3 and all have a unlimited limit, described front template 2 is connected with injecting machine material tube 1 outer face by the locking nut 5 on backstay 3, described injecting machine material tube 1 outer face is provided with a plurality of positioning convex 11, and the inner face of described front template 2 is provided with a plurality of detents 10 that match with positioning convex 11.
