Abstract
The utility model discloses a lap joint mould. The lap joint mould comprises an upper mould and a lower mould which is matched with the upper mould, wherein a faying surface of a core of the upper mould and the lower mould is a stepped surface. When a mould bridge deforms, the core deviates, due to fact that the faying surface of the core and the lower mould is the stepped surface, two gaps are generated between the faying surface of the core and the lower mould, the two gaps are respectively a first gap and a second gap, the two gaps are mutually staggered and both are blind gaps, namely the first gap and the second gap cannot penetrate through the whole faying surface of the core and the lower mould in a flow direction of liquid metal, and the liquid metal cannot penetrate through the faying surface of the core and the lower mould. Therefore, flashes of profiles produced by the lap joint mould are small, the sizes of the flashes of the profiles are reduced, and therefore influences from the flashes on profile quality are reduced.
Description
Technical field
The utility model relates to cantilever section bar manufacturing technology field, more particularly, relates to a kind of overlap joint mould.
Background technology
At present, generally adopt flat-die production for the cantilever section bar.For example, big cantilever section bar as shown in Figure 1 adopts flat-die 11 to produce, and flat-die 11 as shown in Figure 2.Because liquid metal extrusion modling in flat-die 11, the cantilever 111 in the flat-die 11 is longer, more easily is to rupture in the A place at the narrowest place, causes the service life of flat-die 11 shorter.In order to improve the service life of mould, adopt " false shunting mould " to produce, as shown in Figure 3-4, cantilever 111 is divided into two parts, a part is as the core print 121 of patrix 12, another part is as the part of counterdie 13, the core print 121 of patrix 12 and counterdie 13 overlap joints, and core print 121 is seamless with the lap-joint of counterdie 13, thus eliminated the cantilever 111 in the mould, thereby avoided collapsing and causing mold damage because of cantilever 111 fractures, pressure, improved the service life of mould.
But, along with increasing of mould access times, the mould bridge 122 of patrix 12 can be stayed distortion, as shown in Figure 5, the core print 121 that links to each other with mould bridge 122 also can be along with deforming, cause core print 121 and its initial position to be offset, because core print 121 only is one with the faying surface of counterdie 13, make the lap-joint of core print 121 and counterdie 13 gap occur and whole faying surface is run through in this gap, and this gap is parallel to the flow direction of liquid metal, and as shown in Figure 6, then liquid metal can be full of whole faying surface, bigger overlap will appear in the section bar with this mould production, has a strong impact on the quality of section bar.
In sum, how reducing the overlap of section bar, to reduce overlap to the influence of section quality, is present those skilled in the art's problem demanding prompt solution.
The utility model content
The purpose of this utility model provides a kind of overlap joint mould, reduces the overlap of section bar, to reduce overlap to the influence of section quality.
To achieve these goals, the utility model provides following technical scheme:
A kind of overlap joint mould comprises patrix and the counterdie that matches with described patrix; Wherein, the faying surface of the core print of described patrix and described counterdie overlap joint is cascaded surface.
Preferably, in the above-mentioned overlap joint mould, the ladder number of plies of described faying surface is two-layer, and described faying surface comprises first cascaded surface and second cascaded surface, and wherein, described first cascaded surface is near the bottom of described core print.
Preferably, in the above-mentioned overlap joint mould, the width of the width of described first cascaded surface and described second cascaded surface equates.
