Description
Technical field
The utility model belongs to aluminium alloy extrusion mould design field, in particular to eight muscle rotation fancy outer circle rolling in one kind
Cylinder mould tool.
Background technique
Mold design is most important in aluminium alloy extruded production, and structurally reasonable mould strength is good, extruding force is small, stablizes
Property is good, throughput is big, the service life is long, qualification rate is high, however, the structure of product often determines the design direction of mold, such as in life
When producing fancy outer circle roller, since the structure is outer ring intermediate solid, support, Ji Yaobao are connected by rotating the muscle of fancy
The feed for demonstrate,proving roller intermediate solid part guarantees the intensity of all small special-shaped square holes again, eight muscle in one kind is then just needed to revolve
Turn fancy outer circle drum die.
Utility model content
In view of this, the purpose of this utility model, which is to provide for eight muscle in one kind, rotates fancy outer circle drum die, make it
It while capable of guaranteeing centre of the drum's solid section feed, and can guarantee the intensity of all small special-shaped square holes, improve aluminum profile
Processing efficiency.
One aspect according to the present utility model, provide in eight muscle rotation fancy outer circle drum die, including upper mold and
Lower die, upper mold are fastened on lower die, fling in the middle part of upper mold feed end equipped with counterbore, and counterbore, which is flung, is divided into two layers inside and outside, upper mold charging
It holds circumference to be equipped with multiple tap holes, shunt bridge is equipped between two adjacent tap holes, lower die feed end is equipped with die cavity, mould
Chamber is equipped with choked flow platform, can either guarantee that centre of the drum's solid section is fed as a result, and can guarantee the strong of all small special-shaped square holes
Degree.
Further, tongue core is equipped in the middle part of upper mold discharge end, tongue core is equipped with empty knife, and lower die is equipped with die hole, tongue core and die cavity
Between form bonding container, form work belt between empty knife and bonding container, thereby, it is possible to stable prod size, guarantee product surface
Quality.
Further, upper mold feed end even circumferential is distributed four tap holes, and tap hole is ellipse setting and and soldering
Room communicates, and tap hole is equipped with rounded corner keeps mould inner pressure uniform thereby, it is possible to control labor and materials flow, reduces labor and materials to mold
Pressure, enhance die life.
Further, positioning pin is equipped between upper mold and lower die, and is connected by the screw in screw hole, as a result, on
Seamless cooperation between mould and lower die, reduces the aperture on mold, increases the intensity of mold.
Further, the rounded setting of choked flow platform, the center of circle are located at the geometric center of the lower die, the high 3mm of choked flow, as a result,
It can control into aluminium flow velocity, balanced-out material.
The utility model can either guarantee that centre of the drum's solid section is fed, and can guarantee the strong of all small special-shaped square holes
Degree improves aluminum profile processing efficiency.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view that eight muscle rotate fancy outer circle drum die in the utility model.
Fig. 2 is the structural schematic diagram that interior eight muscle of Fig. 1 the utility model rotates the upper mold of fancy outer circle drum die.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, 2, which rotates fancy outer circle drum die, including upper mold 1 and lower die 2, upper mold 1 are fastened on
Lower die 2,1 feed end of upper mold middle part are equipped with counterbore and fling 3, and it is inside and outside two layers 31 that counterbore, which flings 3 points, is increased by mold center
Counterbore flings 3, it is ensured that and central feeding enhances the intensity of all small special-shaped square holes, and it is inside and outside two layers 31 that counterbore, which flings 3 points,
In turn ensure the feed of outer circle inner wall；
1 feed end circumference of upper mold sets the oval setting of tap hole 4 there are four tap hole 4, and communicates with bonding container 11,
The reasonable Arrangement of tap hole 4 balances into aluminium flow velocity, reduces squeeze pressure, flowing and soldering, tap hole 4 is promoted to be correspondingly arranged
Chamfering 13, shunt bridge 5 is equipped between the tap hole 4 of adjacent two, and the entrance side of shunt bridge 5 from the feed end of upper mold is supreme
The section of the outlet side of the discharge end of mould be it is arc-shaped, effectively remove as a result, on part because machining generate burr, guarantee produce
The stability of product；2 feed end of lower die is equipped with die cavity 6, and die cavity 6 is equipped with choked flow platform 7, the rounded setting of choked flow platform 7, under the center of circle is located at
The geometric center of mould 2, the high 3mm of choked flow, thereby, it is possible to control into aluminium flow velocity, balanced-out material；
Positioning pin 14 is equipped between upper mold 1 and lower die 2, positioning pin 14 has upper mold 1 and lower die 2 quickly
Merge, and be connected by the screw in screw hole 15, so that the seamless connection of upper mold 1 and lower die 2, increases mould strength；
Be equipped with tongue core 8 in the middle part of upper mold 1 discharge end, tongue core 8 is equipped with empty knife 9, and 2 feed end of lower die is equipped with die hole 10, tongue core 8 with
Bonding container 11 is formed between die cavity 6, bonding container 11 is arranged to scalariform type, can control the labor and materials soldering time, and enhancing aluminium alloy is strong
Degree forms work belt 12 between empty knife 9 and bonding container 11, the work belt value of middle part good fluidity is long, edge, corner stream
The work belt value of dynamic property difference is shorter, by the value of work belt come stable article size, guarantees products surface quality, as a result,
The utility model increases its intensity while capable of providing balanced feed to product again, improves the processing efficiency of aluminum profile.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
