Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the structural representation of replaceable core rod described in the utility model.
Fig. 4 is the structural representation of product described in the utility model.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As Figure 1-4：The aluminum alloy heat, which extrudes replaceable mold cores, includes upper mould 1, lower mould 2, die sleeve 3, screw
4th, the first supporting pad 5, the second supporting pad 6, core rod 7, replaceable core rod 8, stud 9, upper die worker makees band 10, lower die worker makees band 11,
Pin 12, aluminium alloy 13, product 14, the first tap hole 15, the second tap hole 16, first work band 17, second work band 18,
Eccentric circular hole 19 etc..
As shown in Fig. 2 aluminum alloy heat described in the utility model, which extrudes replaceable mold cores, includes upper mould 1 and lower mould 2, on
Mould 1 and lower mould 2 are connected by screw 4 and pin 12, and upper mould 1 and lower mould 2 have been arranged at the mould that fixed support mode acts on
In set 3；As shown in figure 1, the upper mould 1 is provided with multiple first tap holes 15 and multiple second tap holes 16, it is provided with upper mould 1
Core rod 7, detachably two replaceable core rods 8 is provided with core rod 7, two replaceable core rods 8 are in eccentric setting, i.e., two replaceable
Not on the same line, the position correspondence of this two replaceable core rods 8 is in product 14 as shown in Figure 4 for the horizontal center line of core rod 8
Two eccentric circular holes 19；As shown in figure 3, the replaceable core rod 8 is fixed on upper mould 1 by stud 9；The core rod 7 it is interior
The first work work band 18 of band 17 and second of mutual cooperation, core rod 7 are set respectively on surface and the outer surface of replaceable core rod 8
The upper die worker of formation makees band 10 between lower mould 2 and lower die worker makees band 11, and upper die worker makees the outer surface that band 10 is located at core rod 7, lower mould
Work band 11 is located at lower mould 2；The discharge end of the lower mould 2 sets the first supporting pad 5 and the second supporting pad 6.
Operation principle and the course of work of the present utility model：When producing extruding, set of molds is encased in fixation after getting togather
In the die sleeve 3 of support mode, put it to above extruder and then start extruding production；As shown in figure 1, aluminium alloy 13 is from mould
The die face that front end keeps up with mould 1 first contacts, and aluminium alloy 13 then flows into the first tap hole 15 and the inside of the second tap hole 16, first
After the tap hole 16 of tap hole 15 and second is internally formed sufficiently large pressure, then it is flowed into the first work band 17, second work band
18th, upper die worker makees band 10 and lower die worker makees band 11, is flowed out again after above-mentioned work band is internally formed the shape of product 14, departs from
After work band, now product 14 somewhat cools down, then by the first supporting pad 5 and the second supporting pad 6, product 14 is
Through fully hardened sizing, such a complete production extrusion process just completes.
The core rod 7 is all machined not in accordance with traditional processing method by EDM (spark-erosion machine tool), but
The center section of core rod 7 uses the structure of replaceable core rod 8, using inlaying（Screw thread coordinates）Form replaceable core rod 8 is coordinated
Up；Maximum difficulty is that replaceable core rod 8 is in eccentric position, and Conventional processing methods can not be completed, it is necessary to special using CNC
Processing method is carried out；Advantage of this is that substantially reducing the process-cycle of mould, the machining accuracy of mould is improved, simultaneously
Also improve efficiency and the mold use life-span of production.
