For the irregular irregular section bar of cross sectional shape, particularly the one-sided irregular section bar surface that combines curved surface having as arc surface, arc surface and plane or inclined-plane, does not also have appropriate technology means to realize in its curved surface embossing at present.
Utility model content
The applicant, for above-mentioned problem, is studied improvement, and a kind of extrusion die that can be to the embossing of plastic irregular profile curved surface is provided, simple in structure, low cost of manufacture, and solution cannot be in the problem of plastic irregular profile curved surface embossing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of extrusion die that can be to the embossing of plastic irregular profile curved surface, comprise machine neck, shunting rack template, core rack template, compression template, preformed template, forming panel, core and spreader, described spreader is fixedly connected on the tail end of described core, described core connects described core rack template and is sleeved in the die cavity of described machine neck, shunting rack template, core rack template, compression template, preformed template, forming panel, and the front end of described core extends to the elongated surfaces of extruding end face of described forming panel; The end of extruding of described forming panel is provided with pressure roller mounting groove, pressure roller is arranged in described pressure roller mounting groove, the two ends of the described pressure roller described forming panel that is rotatably connected, the axis of rotation of described pressure roller is parallel to the end face of extruding of described forming panel, and the axis of rotation of described pressure roller is positioned at the inner side of extruding end face of described forming panel, described pressure roller profile and plastic irregular profile curved surface match, and roller surface is provided with decorative pattern.
Further:
The two ends of the described pressure roller slide block that is rotatably connected respectively, described slide block is slidably arranged in described pressure roller mounting groove, fixed block is fixedly connected with described forming panel, the front end of two adjusting screw(rod)s of described fixed block of being threaded connects respectively described slide block, and the center line of two described adjusting screw(rod)s is perpendicular to the axis of rotation of described pressure roller and be positioned at same plane with the axis of rotation of described pressure roller.
The distance of extruding end face of the axis of rotation of described pressure roller and described forming panel is between 3 ~ 15 millimeters.
The distance of extruding end face of the axis of rotation of described pressure roller and described forming panel is 9 millimeters.
Described core is provided with cross inner rib sprue.
Technique effect of the present utility model is:
The disclosed a kind of extrusion die that can be to the embossing of plastic irregular profile curved surface of the utility model, simple in structure, low cost of manufacture, solution cannot be in the problem of plastic irregular profile curved surface embossing, further improve the decorative effect on plastic irregular profile surface, meet the different demands in market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A place cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As Fig. 1, shown in 2, the utility model comprises machine neck 1, shunting rack template 2, core rack template 3, compression template 4, preformed template 5, forming panel 6, core 7 and spreader 10, machine neck 1, shunting rack template 2, core rack template 3, compression template 4, preformed template 5, forming panel 6 is fixedly installed togather by screw, spreader 10 is fixedly connected on the tail end of core 7, core 7 connecting-type core support templates 3 are also sleeved on machine neck 1, shunting rack template 2, core rack template 3, compression template 4, preformed template 5, in the die cavity of forming panel 6, the front end of core 7 extends to the elongated surfaces of extruding end face C of forming panel 6, what that is to say the front end face of core 7 and forming panel 6 extrudes end face C in same plane, on core 7, be also provided with cross inner rib sprue 701.The end face C place that extrudes of forming panel 6 is provided with pressure roller mounting groove 9, pressure roller 8 is arranged in pressure roller mounting groove 9, the profile of pressure roller 8 and plastic irregular profile curved surface match, and the surface of pressure roller 8 is provided with decorative pattern, in the present embodiment, plastic irregular profile surface is by one section of straight line and one section of curved surface that camber line forms.The two ends of pressure roller 8 are respectively by the bearing slide block 11 that is rotatably connected, slide block 11 is slidably arranged in pressure roller mounting groove 9, fixed block 12 is fixedly connected with forming panel 6, fixed block 12 is equally also arranged in pressure roller mounting groove 9, and side of slide block 11 and a side of fixed block 12 stick together, to slide block 11 certain guide effect of having slided.Be threaded fixed block 12 two adjusting screw(rod)s 13 front end respectively the center line of 11, two adjusting screw(rod)s 13 of connection sliding block perpendicular to the axis of rotation of pressure roller 8 and be positioned at same plane with the axis of rotation of pressure roller 8.What the axis of rotation of pressure roller 8 was parallel to forming panel 6 extrudes end face C, and the axis of rotation of pressure roller 8 is positioned at the inner side of extruding end face C of forming panel 6, conventionally the axis of rotation of pressure roller 8 and the distance B that extrudes end face C of forming panel 6 are arranged between 3 ~ 15 millimeters, in the present embodiment, the distance B that extrudes end face C of the axis of rotation of pressure roller 8 and forming panel 6 is 9 millimeters.When practical operation, when plastic irregular profile is in forming panel 6 extrusion molding time, the profile shapes of moulding promotes pressure roller 8 and rotates, pressure roller 8 suppresses embossing on profile shapes curved surface, because pressure roller 8 and the contact point below of profile shapes curved surface have core 7 to exist, the downforce that pressure roller 8 produces when compacting embossing is born by core 7, can not make the section bar after moulding bend.In addition, the spacing of being adjusted between pressure roller 8 and core 7 by adjusting screw(rod) 13, is controlled in suitable scope the degree of depth of embossing and pressure.
