detailed description of the invention:below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model provides a kind of fast-assembling floating-type core structure being applied to porous mould, and this structure comprises the core 1 and core print seat 2 two parts that can dismantle and assemble; The bottom of core is provided with locating dowel 3, and core print seat is provided with the locating slot or locating hole 4 that match with this locating dowel, and during use, locating dowel is arranged on the connection realizing core and core print seat in locating slot or locating hole.
Core and locating dowel are divided into integral type to be connected and assembly type connects;
When core and locating dowel be integral type be connected time, locating dowel is oval back taper cylinder, the section diameter that this back taper cylinder is connected with core is the thinnest, expand gradually downwards afterwards, form up-small and down-big structure, these oval back taper cylinder two sides 5 are cylinder or plane, both ends of the surface 6 are the conical surface or hemisphere face, the bottom of back taper cylinder is made to form oval structure, namely the major diameter direction of this oval back taper cylinder is cylinder or plane, minor axis direction is the conical surface or hemisphere face, the major diameter of core print seat locating slot and the size of minor axis are greater than the major and minor axis of core locating dowel, ensure that the gap of locating dowel and locating hole is installed, core print seat 2 is provided with the chute 7 through with locating slot, this chute 7 is the chute that can hold locating dowel minor axis width, the major diameter direction of core print seat locating hole is vertical with the length direction of chute 7,
When core and locating dowel be assembly type be connected time, locating dowel is inverted cone surface or hemisphere face structure, the position that locating dowel is connected with core is the thinnest, Inner bolt holes 8 is designed with in the baseplane of locating dowel, locating hole on core print seat 2 matches with this locating dowel and adapts to, and is provided with the hole 9 corresponding with the Inner bolt holes position in locating dowel supplying the bolt of stationary positioned post to pass bottom locating hole.
Each core and core print seat split manufacture by the utility model, by the oval back taper locating dowel that designs at core tail end with the oval back taper locating hole (groove) that core print seat designs on the surface, realize the floating connecting structure of core and core print seat.Each to float in level (X, Z axis) direction can trace mobile, but the free degree on vertical (Y-axis) direction is restrained.X, Y, Z axis be exactly level in Fig. 1, vertically with perpendicular to the direction of drawing.
When each floating-type core being inserted in the core demoulding hole 111 on stripper plate, floating-type core original installation position degree in the horizontal direction, under the constraint in demoulding hole, carry out microdisplacement adjustment, fit like a glove with demoulding hole until final, thus complete core position in the horizontal direction and locate.Along with demolding structure rising and move down, core is clamped in the demoulding hole of mould emptier all the time.Now, positioning datum and the core positioning datum in mould emptier demoulding hole merge, and eliminate the contradiction between the many positioning datums between core and demoulding hole, decrease the movement interference between core and demolding structure.In Fig. 1,222 for deviating from position, and 333 is shaping position, and 444 is outer mould bases, and 555 is base, and 666 is core print seat fastening bolt, and 777 for deviating from mechanism.In Figure 14,888 is central layer, and 999 is bolt.
Fast-assembling floating-type core is applicable to various complex core cross section, and the architectural feature of its core devises a kind of locating dowel with inverted cone surface feature at the tail end of core.Locating dowel has two kinds of structures.A kind of is locating dowel and core syndeton integrally; Another kind is the location structure of locating dowel and core separable assembled.The shape of one locating dowel is oval back taper cylinder.The long side direction of locating dowel is the conical surface or hemisphere face, and short side direction is plane or cylinder.
The shape of split locating dowel is hemisphere cylinder or centrum.The baseplane of split locating dowel is designed with hexagon socket head cap screw hole, and locating dowel is connected with core by the form that can be threaded connection.The manufacture of fast-assembling core is applicable to forging, casting, the kinds of processes methods such as machining.
The position of the locating hole on core print seat surface and form and core locating dowel one_to_one corresponding.When being applied to the core print seat of one locating dowel, will offer oval reverse taper holes in the connecting surface of core print seat and core, the long side direction of elliptical aperture is cylinder, and the short side direction of elliptical aperture is the conical surface or hemisphere face.The long limit of core print seat locating hole and the length of minor face are greater than the length edge lengths of core locating dowel, and the gap of such guarantee locating dowel and locating hole is installed.The one core installed at core print seat edge, core print seat can adopt the mode at core print seat edge minor axis chute, sliding plug core.After one core locating dowel moves and inserts core print seat locating hole in chute, by core 90-degree rotation, the floating connection of one locating dowel core and core print seat can be realized.
Have combination install locating dowel working condition under, can on core print seat assembling split locating dowel.The locating hole of the core print seat be connected with split locating dowel is inverted cone surface or hemisphere face structure.Split locating dowel will penetrate core print seat locating hole from the opposite side of core print seat, and by dormant bolt by locating dowel, core print seat, core, disc spring is clamped and connected.
By the fit clearance between adjustment locating dowel and core print seat, the positioning accuracy request of different core can be met, various note pressure work shape body can be applied.
Fast-assembling core, core print seat, the manufacture of demolding structure is applicable to precision forging, hot investment casting, in the multiple moulding technique such as machining.
