The specific embodiment
A kind of hydraulic forming mold device of the utility model comprises die 1, liquid chamber 8.Shown in Fig. 2,3, die 1 is made the concave die cavity consistent with part shape to be formed 11, and liquid chamber 8 is provided with a liquid chamber die cavity 81, also is provided with a fuel feed hole 9 simultaneously, communicates with liquid chamber die cavity 81; Die 1 is provided with groove 2 and seal groove 3, with die 1 correspondingly, also be provided with groove 2 and seal groove 3 on the liquid chamber 8.Shown in Fig. 4 a, 4b, 5a, 5b, be respectively the upper and lower flanging abaculus of the utility model schematic diagram, last flanging abaculus is provided with flanging projection 451, following flanging abaculus is provided with flanging groove 452, set flanging projection 451 is agreed with mutually with flanging groove 452 on the corresponding upper and lower flanging abaculus, forms a pair of.
As shown in Figure 1, last flanging abaculus 4a, 5a and die 1 are chimeric, and following flanging abaculus 4b, 5b and liquid chamber 8 are chimeric, are provided with sealing ring 31 in the seal groove, with the sealing of a kind of hydraulic forming mold device of further raising the utility model.Insert 6 respectively with last flanging abaculus 4a and 5a, flanging abaculus 4b and 5b are chimeric fixing down by two pairs of flanging, simultaneously by screw 7 fixedly flanging insert 6.Wherein the sectional dimension of two pairs of flanging abaculus, shape are identical, but according to the gauge of welding plate is different different choice are arranged with the sectional dimension of the corresponding flanging projection of flanging abaculus, shape.
To have with the suitable flanging of welding plate 10 thickness to be formed flanging abaculus protruding and the flanging groove and be entrenched in the utility model hydraulic forming mold device, insert and screw is fixed by flanging, to weld plate 10 and place liquid chamber 8 tops, welding plate 10 sheet section and slab part place respectively on the two flanging abaculus, in the utility model, sheet section places flanging abaculus 4b place, slab partly places flanging abaculus 5b place, welding plate 10 forms the one side and liquid chamber die cavity 81 homonymies of weld seam step 101, closed die 1, flanging groove and flanging projection are agreed with, with concave die cavity in the mould 11 and 81 sealings of liquid chamber die cavity.Fuel feed hole 9 fill liquid in liquid chamber die cavity 81 that utilizes compression pump to pass through on the liquid chamber 8 pressurizes, and the distortion of bulging one pull and stretch compound plastic takes place welding plate 10 under pressure, until the inwall applying of welding plate 10 with die 1, obtains needed part.
As Fig. 6, another embodiment of the utility model shown in Figure 7, the structure of its structure and first embodiment is roughly the same, but the welding plate that is acted in the present embodiment is to be formed by the welding of the plate of three different-thickness, form two weld seam steps 101, so a kind of hydraulic forming mold device of the utility model partly locates to have adopted altogether four pairs of flanging abaculus 45 in the different thin and thicks of correspondence.Similarly, by flanging insert 6 and screw 7 flanging abaculus 45 is fixing.
When the utility model acts on different welding plates, only need structure according to used welding plate, employed flanging abaculus number is adjusted got final product.
