Description

Aluminium alloy extruded decoration post mold

Technical field

The present invention relates to a kind of aluminium alloy extrusions for showing product, more particularly to a kind of aluminium alloy extruded edge list mould Tool.

Background technology

China is industrial power, and as the manufacturing industry in progress China of science and technology flourishes, economy is become stronger day by day, new technology New material constantly emerges in large numbers, wherein one of aluminium alloy, and it has excellent mechanical performance and chemical property, is widely used in Various fields, aluminium section bar is such as usually used in environmental decoration, but be mainly used in building for frame structure, in light weight, connection side Just, texture and decorative effect protrude, and this respect application is more more, other aspects then apply it is less, as in pipeline, post The product not just being applicable in decoration；Existing aluminium alloy extrusions is mostly produced by expressing technique, and production extrusion molding is hollow During tubular products, aluminium alloy base will first enter multiple runners and reach extrusion, then converges and combine together by extrusion extrusion molding, Aluminium alloy base, which enters during multiple runners, is separated into that multichannel is invisible to improve resistance, it is necessary to which higher squeeze pressure could be into Type, influenceed by stable process conditions fold or crack also easily occur when multichannel aluminium alloy base converges, these are still up for skill Art solves.

The content of the invention

In order to solve the above problems, the invention provides a kind of aluminium alloy extruded decoration post mold.

The technical solution adopted by the present invention is：A kind of aluminium alloy extruded decoration post mold, it is characterised in that including cross section Curved big curved wall runner and small curved wall runner, big curved wall runner and small curved wall flow channel cross-section arc Shape track is isometrical, and small curved wall runner is located at below big curved wall runner, big curved wall flow channel cross-section arching trajectory Institute is 240 degree to central angle, and small curved wall flow channel cross-section arching trajectory institute is 120 degree to central angle, big curved wall stream Road edge is provided with the overhead kick runner for pointing to the center of circle, and small curved wall runner edge is provided with buckle runner, the small curved wall of extrusion pin On buckle engage to form a cylinder with the overhead kick on big curved wall；Longitudinal midline both sides point in big curved wall runner arc Main shell fragment runner is not connected, and main shell fragment runner lodges to the center line direction of big curved wall runner, in small curved wall runner arc Longitudinal midline both sides difference auxiliary connection shell fragment runner, secondary shell fragment runner lodges to small curved wall center line direction.

Further, the inwall of the big curved wall runner and small curved wall runner is provided with band gap circular hole stream Road, the cylinder axle center that gap surrounds towards output product, circular hole are 3 and are uniformly distributed in circumferential.

Further, the big curved wall runner and small curved wall runner edge are provided with process seam runner, big arc The outer midline position of side wall runner arc is provided with the process seam runner of same shape.

Be non-occluded configuration during aluminium alloy extrusions of the present invention extrusion, without setting runner to extrusion die outlet, it is necessary to Squeeze pressure is smaller, it is necessary to which energy expenditure is smaller, and aluminium material surface fold and crack occurrence probability are small, can be very easily during use Fasten；Then extrusion pin fastens small curved wall, makes shell fragment and pipeline in use, pipeline or post are caught in big curved wall Or post contact, ensure Stability Analysis of Structures, there is good texture, improve dicoration, improve ambiance and render.

Embodiment

As shown in Figure 1, 2, the aluminium alloy extruded decoration post mold includes the curved big arc in cross section to the embodiment of the present invention Shape side wall runner 1 and small curved wall runner 2, for extruding big curved wall 3 and small curved wall 4, big curved wall runner Isometrical with small curved wall flow channel cross-section arching trajectory, small curved wall runner is located at below big curved wall runner, big arc Shape side wall flow channel cross-section arching trajectory institute is 240 degree to central angle, and small curved wall flow channel cross-section arching trajectory institute is to circle Heart angle is 120 degree, and big curved wall runner edge is provided with the overhead kick runner 5 for pointing to the center of circle, in big curved wall longitudinal edge Edge is extruded into overhead kick 6, and small curved wall runner edge is provided with buckle runner 7, for being extruded in small curved wall longitudinal edge Buckle 16 is formed, the buckle on the small curved wall of extrusion pin engages to form a cylinder with the overhead kick on big curved wall；Big arc Longitudinal midline both sides in side wall runner arc connect main shell fragment runner 8 respectively, for being extruded into main shell fragment 9, main shell fragment runner Lodged to the center line direction of big curved wall runner, the longitudinal midline both sides difference auxiliary connection shell fragment in small curved wall runner arc Runner 10, for extruding secondary shell fragment 11, secondary shell fragment runner lodges to small curved wall center line direction；Extrusion pin is in use, will pipe Road or post are caught in big curved wall, are then fastened small curved wall, shell fragment is contacted with pipeline or post, ensure Stability Analysis of Structures, The amplitude that shell fragment is upspring under normality can be set as needed, and such as good can of big curved wall deformability is by shell fragment normality bullet The amplitude of rising is done smaller, big curved wall can be combined when pipeline or post are caught in deforms and realize, such as big curved wall is variable Shape is bad, then can do the shell fragment normality amplitude of upspringing few larger, and shell fragment suppresses circle diameter where position and is similar to The air line distance of the big longitudinal edge of curved wall two, it can combine when pipeline or post are caught in and be realized by shell fragment deformation, be connected It is stable that there is good texture, dicoration is improved, ambiance is improved and renders；Big curved wall runner and small curved wall runner It is connected with arc for forming the circular hole runner 13 with gap circular hole 12, the axle center for the cylinder that output product gap direction surrounds, circle Hole is 3 and is uniformly distributed in circumferential.In circular hole be provided with positioning pin, cylinder indefinite extension can be spliced, it is also possible to Branch pipe tee connection position sets joint, installation needs can be adapted to when splicing cylinder with 120 degree of direction of rotation, in big curved wall runner Be provided with process seam runner at small curved wall runner longitudinal edge, the outer midline position of big curved wall runner arc is provided with phase similar shape The process seam runner 14 of shape, for being extruded into process seam 15, outward appearance integrally feels more well-balanced, there will not be after 120 degree of rotations The sensation of dislocation；It is non-occluded configuration during aluminium alloy extrusions extrusion of the present invention, without setting runner to be exported to extrusion die, needs Want squeeze pressure smaller, it is necessary to which energy expenditure is smaller, aluminium material surface fold and crack occurrence probability are small, and can be very during use It is convenient to fasten.

It is only present pre-ferred embodiments in summary, all equivalent modification done according to the application and prior art additions are equal It is considered as the technology of the present invention category.
