Description
Technical field
The present invention relates to curtain plastic guide rail production equipment technical field, specifically be a kind of plastic guide rail mould of curtain.
Background technology
Curtain plastic guide rail generally adopts plastics extrusion die extrusion molding.At present, threaded backstay is all adopted to locate for the production of between the front template of the plastic guide rail mould of curtain of curtain plastic guide rail and the barrel discharging opening of injection machine, namely barrel is provided with multiple backstay, front template is provided with multiple locating hole coordinated with backstay, to be coordinated with locating hole by backstay and front template and barrel are located, and by the locking nut on backstay, front template and barrel being locked, be provided with guide rail die cavity in this front template, this guide rail die cavity communicates with barrel inner chamber.When curtain plastic guide rail is produced, first plastic grain to be melted is put into barrel, heater on barrel outer wall heats barrel, thus the plastic grain in barrel is melted, then the worm screw of barrel the inner extrudes the plastics after melting under the driving of hydraulic cylinder, guide rail die cavity on plastic warp front template after fusing is outwards extruded, thus forms shaping plastic guide rail.Between the front template of this plastic guide rail mould of curtain 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 decline; Moreover the plastics of molten state under high pressure outwards can overflow along the junction of front template and barrel discharging opening, thus entering in the locating hole of front template, causing when changing front template, need the very large power of expense just can take off front template, it is very inconvenient to change.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defect of above prior art, provides positioning precision between a kind of front template and injecting machine material tube high, and the plastic guide rail mould of curtain of front template easy accessibility.
Technical solution of the present invention is, there is provided a kind of plastic guide rail mould of curtain with following structure: it comprises injecting machine material tube and the front template with die cavity, described injecting machine material tube outer wall is provided with heater, the inner chamber of worm screw and accommodating plastic grain is provided with in injecting machine material tube, described front template is connected with the outer face of injecting machine material tube is removable, and the intracavity inter-connection of die cavity on front template and injecting machine material tube, described injecting machine material tube is provided with multiple threaded backstay, front template is provided with multiple matching with backstay and the locating slot all having that opens wide limit, described front template is connected with injecting machine material tube outer face by the locking nut on backstay, described injecting machine material tube outer face is provided with multiple positioning convex, and the inner face of described front template is provided with multiple detent matched with positioning convex.
After adopting above structure, plastic guide rail mould of curtain of the present invention compared with prior art, have the following advantages: this plastic guide rail mould of curtain in a pre-installation template time, first make backstay on injecting machine material tube through the locating slot on front template, and make the multiple positioning convex on injecting machine material tube outer face be engaged in the detent on front template inner face, then with locking nut, front template is fixed on injecting machine material tube outer face; Because the multiple positioning convex on injecting machine material tube outer face coordinates with the detent on injecting machine material tube outer face, in the process of front template handling, even if the locating slot on backstay and front template can cause wearing and tearing, also can not affect the assembly precision of front template, therefore between front template and injecting machine material tube outer face, positioning precision is high; Moreover, even if the plastics that the junction of front template and injecting machine material tube is outwards overflowed drop in the locating slot of front template, when front template is dismantled, back 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 in " work " font.
As preferably, described backstay is fixedly connected with injecting machine material tube by alignment pin.
