The side of chamber, the type chamber is equipped with work belt；Bonding container is equipped with above the type chamber.
As an improvement of the above scheme, the type chamber include the upper side wall for frame-type aluminium alloy, lower wall, left side wall and
The molding upper chamber of right side wall, lower chambers, left chamber and right chamber, and the central bore for vertical shaping.
As an improvement of the above scheme, positioned at the left and right sides main tap hole respectively with corresponding left chamber or right chamber just
It is right, the outside of corresponding upper chamber or lower chambers is set to positioned at the main tap hole of upper and lower two sides.
As an improvement of the above scheme, the central tap hole and central bore's face.
As an improvement of the above scheme, the upper end of the heavy bridge is equipped with water conservancy diversion inclined-plane, and top is equipped with platform.
Implement the utility model, has the following beneficial effects:
The utility model is fed type chamber by 2 central tap holes and 4 main tap holes, can by adjust into
Enter the melt amount of type chamber to control extruded velocity；The center tap hole is symmetrically set in the middle part of upper mold, two central tap holes
Between be equipped with heavy bridge, can reduce the pressure of central tap hole hole wall, extend die life.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.Only this state, the utility model occur in the text or will occur upper and lower, left and right, it is preceding,
Afterwards, the orientation such as inside and outside word is not the specific restriction to the utility model only on the basis of the attached drawing of the utility model.
As Figure 1-Figure 4, the utility model embodiment provides a kind of molding die of frame-type aluminium alloy, the frame-type
More than two facades are equipped in aluminium alloy.The mold includes upper mold 1 and lower die 2, and the upper mold 1 is equipped with 2 centers and shunts
The main tap hole 4 in hole 3 and 4, the center tap hole 3 are symmetrically set in the middle part of upper mold 1, are equipped between two central tap holes 3
Heavy bridge 5；Some edge of heavy bridge, that is, tap hole is lower than other edges.The main tap hole 4 is set around the central tap hole 3
It sets；The lower die 2 is equipped with the matched type chamber 6 of cross sectional shape with frame-type aluminium alloy, and the side of the type chamber 6 is equipped with work belt 7；
Bonding container 8 is equipped with above the type chamber 6.
The utility model is fed type chamber 6 by 2 central main tap holes 4 of tap hole 3 and 4, can pass through tune
Section enters the melt amount of type chamber 6 to control extruded velocity；The center tap hole 3 is symmetrically set in the middle part of upper mold 1, two centers
It is equipped with heavy bridge 5 between tap hole 3, can reduce the pressure of central 3 hole wall of tap hole, extends die life.
Wherein, the type chamber 6 includes the upper side wall 91 for frame-type aluminium alloy, lower wall 92, left side wall 93 and right side wall
94 molding upper chamber 61, lower chambers 62, left chamber 63 and right chamber 64, and it is used for the molding central bore 65 of facade 95.
Respectively with 64 face of corresponding left chamber 63 or right chamber, the master positioned at upper and lower two sides divides main tap hole 4 positioned at the left and right sides
Discharge orifice 4 is set to the outside of corresponding upper chamber 61 or lower chambers 62.The center tap hole 3 and 65 face of central bore.
Preferably, the upper end of the heavy bridge 5 is equipped with water conservancy diversion inclined-plane 51, and top is equipped with platform 52.
The working principle of this mold is as follows: before extruding, upper mold 1 and the molding of lower die 2 are packed into extruder, and aluminium alloy melt exists
Enter under the pressure effect of extruder from the tap hole of upper mold 1, due to being equipped with heavy bridge 5, the height at heavy 5 position of bridge between tap hole
Lower than the apparent height of upper mold 1, the flowing velocity of melt can be accelerated, while lowering the pressure of tap hole.The heavy bridge 5 it is upper
End is equipped with water conservancy diversion inclined-plane 51, and top is equipped with platform 52, and the platform 52 improves the intensity of heavy bridge 5, prevents the impact in melt
It is lower to wear, the service life of mold is promoted, extension repairs a die the period, and melt can be oriented to tap hole by the water conservancy diversion inclined-plane 51.It is molten
Body carries out soldering after the shunting of tap hole, into bonding container 8, finally in inflow type chamber 6, in the Secondary Control of work belt 7
Effect is lower to squeeze the aluminium alloy that Formation cross-section is frame-type.By above-mentioned forming method, the melt of frame-type aluminium alloy different location is needed
It asks and is targetedly met, reduce the internal stress for squeezing finished product, aluminium cooling procedure will not secondary deformation after extrusion forming.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly cannot be practical to limit with this
Novel interest field, therefore equivalent variations made according to the claim of the utility model still belong to what the utility model was covered
Range.
