Embodiment
The mould of the utility model air conditioning for automobiles connector, including upper die and lower die.As shown in Figure 4 and Figure 5, upper mould
200 include upper die body 210, the compression leg 220 for being connected to the lower section of upper die body 210 and the drift 230 for being connected to the lower section of compression leg 220.
Wherein, the end face of compression leg 220 has the annular groove 221 around drift 230 and the forming ends around drift 230
Face 222.The annular groove 221 is used for the centring ring for being molded air conditioning connector, and shaping end face 222 is used to be molded air conditioning connector
The curved weld face of flange connector.Specifically, shaping end face be both sides be symmetrically upturned, middle downward projection of arcwall face,
Shape is corresponding to the shape in the curved weld face of the flange connector of air conditioning connector；The bottom surface of annular groove the root of drift with
Shaping end face shape rises and falls and have circumferentially be spaced apart be molded air conditioning connector centring ring positioning convex into
Type pit 223；
The lower end of drift 230 has cone-shaped end 231, and the height of cone-shaped end 231 is 13mm, and taper is 60 degree.Drift
230 diameter is identical with the internal diameter of the body of connector.
As Figure 6-Figure 8, lower mould 300 has interconnected upper circular hole chamber 310 and lower circular hole chamber 320, upper circular hole chamber
Smoothly transitted between 310 and lower circular hole chamber 320 by arc forming surface 330；Arc forming surface 330 is used to be molded air conditioning connector
Flange connector outer surface.Specifically, arc forming surface 330 is that both sides are upturned, centre connects to lower recess, shape and air-conditioning
The flange connector outer surface for connecing device is corresponding.The diameter of circular hole chamber 310 be able to be put into blank 100 on air-conditioning, accomplish blank as far as possible
100 be put into after gap between upper circular hole chamber 310 and blank 100 it is minimum, as long as blank 100 can be put into upper circular hole chamber 320
In.The diameter of lower circular hole chamber 320 is identical with the diameter of the body of connector.
To reduce burr, the compression leg 220 of the upper mould 200 of making is more smaller than the diameter of the upper circular hole chamber 310 of lower mould, but to use up
Amount reduces compression leg 220 and enters the gap after upper circular hole chamber 310 between the two, as long as ensureing that compression leg 220 can smoothly enter upper circular hole
In chamber 310, in the present embodiment, the gap substantially 0.1mm.
The mold use method is：
First make blank：Raw material plate is bought from market, raw material plate is three layers of complex layered plate, and intermediate layer is aluminium alloy layer,
Thickness is 4.2mm, and the upper and lower are pincers solder layer, and thickness is 0.5mm.
Raw material plate cutting is fabricated to circle, a diameter of 27mm, and centre bore 101 is provided with center, aperture is 8mm, this
Sample has just been fabricated to blank 100 as shown in Figure 3.
Then by blank punch forming, process is：
Blank 100 is placed into the upper circular hole chamber 310 of lower mould 300 so that drift 230 is directed at the lower circular hole chamber 320,
So that mould 200 is pushed in the warping part of the arc forming surface in the lower mould of the warping part alignment of the shaping end face in upper mould, driving, allow
The cone-shaped end 231 of drift 230 is introduced into the centre bore 101 of blank 100 so that the material around centre bore downwardly and outwardly expands
Flowing, until drift 230 causes the compression leg 220 and lower mould 300 of upper mould 200 completely into blank, then proceeding to push again
Upper circular hole chamber 310 and arc forming surface 330 coordinate the shape for the flange connector for extruding connector, form semi-finished product；
Pressure when upper punch is pressed is 50T, and speed is 10cm/s.
Semi-finished product edge is modified with the mode of trimming and polishing, air conditioning connector is fabricated to.
The air conditioning connector being fabricated to is taken pictures, photo as shown in Figure 9 is obtained by taking pictures as can be seen that air-conditioning
Solder layer on the curved weld face of connector and the outer surface of body is evenly distributed.
But, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Utility model, and be not used as it is of the present utility model limit, if in spirit of the present utility model, to
Change, the modification of the upper embodiment will all fall in Claims scope of the present utility model.
