Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of extruder mold of high extruding precision, the lateral pressure that in extrusion process, mould is subject to can be made to be uniformly distributed, and improves the dimensional accuracy of finished product aluminium.
In order to solve the problems of the technologies described above, the utility model provides a kind of extruder mold of high extruding precision, comprise upper die and lower die, described counterdie is provided with die cavity, described patrix is provided with core rod and is positioned at middle part charging aperture directly over core rod and is positioned at the peripheral charging aperture of surrounding above core rod, described upper die and lower die coordinate to be installed, described core rod stretches in described die cavity, described core rod comprises the core pieces of more than three spaced preset distances, described core pieces be provided with the orientation of core pieces in the same way and run through the tap hole of all core pieces on the same line simultaneously.
As the improvement of such scheme, the relative surface of described core pieces is perpendicular.
As the improvement of such scheme, the relative surface of described core pieces is parallel to each other.
As the improvement of such scheme, between described core rod and the wall of die cavity, leave preset distance.
As the improvement of such scheme, the diameter of described tap hole is 0.5-2 times of the spacing of two adjacent described core pieces.
As the improvement of such scheme, described tap hole is located at the center of described core pieces.
As the improvement of such scheme, described die cavity comprises the wide rectangular channel coordinated with core rod, and is connected with the side of wide rectangular channel, and length is greater than the narrow rectangular channel of described wide rectangular channel.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-Figure 4, the utility model embodiment provides a kind of extruder mold of high extruding precision, comprise patrix 1 and counterdie 2, described counterdie 2 is provided with die cavity 21, described patrix 1 is provided with core rod 11 and is positioned at middle part charging aperture directly over core rod 11 12 and is positioned at the peripheral charging aperture 13 of surrounding above core rod 11, described patrix 1 and counterdie 2 coordinate to be installed, described core rod 11 stretches in described die cavity 21, described core rod 11 comprises the core pieces 111 of more than three spaced preset distances, described core pieces 111 be provided with the orientation of core pieces 111 in the same way and run through the tap hole 14 of all core pieces 111 on the same line simultaneously.Leave preset distance between described core rod 11 and the wall of die cavity 21, the wall for product is shaping.
The utility model by arrange in described core pieces 111 with the orientation of core pieces 111 in the same way and run through the tap hole 14 of all core pieces 111 on the same line simultaneously, the lateral pressure that adjacent core pieces 111 is produced in extrusion process discharges outside core rod 11, make the pressure distribution in mould molding region even, improve the dimensional accuracy of finished product aluminium, reduction in the numbers of seconds.Specifically, in extruded process, the metallic aluminium between core pieces 111 can be flowed between core rod 11 and the wall of die cavity 21 by tap hole 14, makes the integral pressure of metallic aluminium and flow velocity more even, improves Forming Quality.
Preferably, the surface that described core pieces 111 is relative is perpendicular and is parallel to each other.The perpendicular be parallel to each other is conducive to the smooth-going flowing of metallic aluminium, and forms the work strip of mould, makes metallic aluminium extrusion molding.
Preferably, the diameter of described tap hole 14 is 0.5-2 times of the spacing of two adjacent described core pieces 111.When the diameter of tap hole 14 is in aforementioned proportion, tap hole 14 can play the function of shunting metallic aluminium, can not affect the shaping of metallic aluminium in core pieces 111 simultaneously.
Further, in order to make the overall stress balance of branching process core pieces 111, described tap hole 14 is located at the center of described core pieces 111.
Preferably, in the present embodiment, described die cavity 21 comprises the wide rectangular channel 211 coordinated with core rod 11, and is connected with the side of wide rectangular channel 211, and length is greater than the narrow rectangular channel 212 of described wide rectangular channel 211.Described wide rectangular channel 211 and narrow rectangular channel 212 coordinate shaping.
Preferably, described peripheral charging aperture 13 comprises four the first peripheral charging aperture 13a being symmetrically set in both sides before and after patrix 1, and is symmetrically set in two the second peripheral charging aperture 13b of patrix 1 left and right sides.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
