Description
Technical field
The utility model belongs to casting technology field, and it is shaping to be specifically related to casting and molding.
Background technology
After casting cleaning, because rising head seat pattern draft is contrary with rising head body, when knocking out rising head, rising head root always remains on foundry goods, adds a large amount of cleaning work amounts and production cost.In addition, traditional wooden rising head stake is not wear-resistant, needs often to change, if rising head stake after wearing and tearing is changed not in time, can cause rising head loam or the defect of drop, add defective products rate.
Utility model content
The utility model for the deficiency that prior art exists, provides a kind of casting and molding to pull out rising head stake with retrodicting just.
For solving the problem, technical solution adopted in the utility model is as follows:
Casting and molding pulls out rising head stake with retrodicting, described rising head stake is arranged on model, model is provided with the guide pile for coordinating with rising head stake, described rising head stake bottom center is provided with fixing stake holes, fixing stake holes is used for holding guide pile, top, rising head stake upper end is provided with protuberance, protuberance surrounding is provided with external screw thread, rising head stake upper end is provided with columned riser pad, riser pad centre is provided with centre bore, centre bore inside is provided with internal thread, the external screw thread of centre bore internal thread and protuberance meshes together and is arranged in rising head stake by riser pad.
As the improvement of technique scheme, described riser pad is also provided with multiple for fixing pilot hole.
As the improvement of technique scheme, it is Φ 4.5mm hole that described pilot hole comprises four diameters, and circumferentially divides equally distribution.
As the improvement of technique scheme, described rising head stake is up big and down small round table-like, has bevelling outside rising head stake.
As the improvement of technique scheme, outside described rising head stake, the angle of bevelling is 8 °.
As the improvement of technique scheme, described riser pad outer diameter D 1 is equal with the upper end maximum dimension D 2 of rising head stake.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
1, retrodict that to pull out rising head stake be aluminum alloy material, rising head noresidue can be realized.Compare with traditional rising head, after casting cleaning knocks out rising head, rising head root can remain the riser pad of 3-5mm, and rising head stake is wooden, easy to wear, needs often to change.Retrodict and pull out the cone angle that rising head stake has 8 °, the position diameter contacted with foundry goods is minimum.Therefore, the intensity at this position is minimum, when rising head is struck in casting cleaning, can rupture, therefore, can realize rising head noresidue on foundry goods in the contact site of rising head and foundry goods.
2, riser pad uses iron nail to be fixed on rising head bottom, be threaded connection with rising head stake, the diameter of riser pad is identical with the diameter on rising head stake top, make between riser pad and rising head stake seamless, film is avoided to be drawn onto in gap, during molding, film strip is rotten, cause rising head drop, foundry goods " misrun ".In addition, also to ensure that the diameter of riser pad is identical with the diameter of rising head lower end, so as riser pad can with rising head seamless link.
3, retrodict and pull out rising head, decrease rising head and remain, reduce oxygen blast workload, save production cost, and reduce defective products rate to a certain extent.
4, the utility model is reasonable in design, and structure is simple, directly can be increased on existing model and apply.

Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
As shown in Figure 1, for casting and molding described in the utility model pulls out rising head stake mounting structure schematic diagram with retrodicting, Fig. 2 is its perspective view, and described rising head stake 3 is arranged on model 8, and model 8 is provided with the guide pile 1 for coordinating with rising head stake 3.Described rising head stake 3 bottom center is provided with fixing stake holes 2, and fixing stake holes 2 is used for holding guide pile 1, and fixing stake holes 2 adopts square hole shape.Top, rising head stake 3 upper end is provided with protuberance 5, and protuberance 5 surrounding is provided with external screw thread.Rising head stake 3 upper end is provided with columned riser pad 7, its external diameter is D1, and riser pad 7 centre is provided with centre bore 4, and centre bore 4 inside is provided with internal thread, the external screw thread of centre bore 4 internal thread and protuberance 5 meshes together, and is arranged in rising head stake 3 by riser pad 7.Described riser pad 7 is also provided with multiple pilot hole 6, by pilot hole 6, riser pad 7 is fixed on rising head.Described riser pad 7 has the pilot hole 6 that four diameters are Φ 4.5mm, and circumferentially divide equally distribution, be arranged on rising head bottom part by these four pilot holes 6.
After rising head stake 3 is fixed on model 8, carry out overlay film, removed by the film at rising head stake 3 top after overlay film, be then screwed in rising head stake 3 by rising head by the internal thread on riser pad 7, the contact site being wrapped in rising head stake 3 and riser pad 7 with yellow adhesive tape seals.
Described rising head stake 3 is up big and down small round table-like, and its upper end maximum gauge is D2, has bevelling outside rising head stake 3, its angle is 8 °, and this bevelling ensures that the sectional area of rising head bottom part is minimum, when knocking rising head, can rupture from the contact site of rising head and foundry goods, reduce rising head and remain.
Model 8 is provided with guide pile 1, is mainly used in fixing and locates rising head stake 3, its size and dimension is corresponding with the fixing stake holes 2 of rising head stake bottom part.Riser pad 7 is for connecting rising head stake 3 and rising head, and the diameter of riser pad 7 is identical with the top end diameter of rising head stake 3, i.e. D1=D2, to facilitate molding, if the diameter of riser pad 7 is not identical with the top end diameter of rising head stake 3, is just easily with film during molding, during cast, causes rising head loam.
Before molding, first rising head and rising head stake 3 are taken out from casting mold, guide pile 1 is stayed on model 8, then rising head stake 3 is taken off from rising head, before overlay film, rising head stake 3 is placed on guide pile 1.
The utility model is retrodicted and is pulled out rising head stake 3 and adopt aluminium alloy to be made, tool has good wearability, and adopt traditional wooden rising head stake more easy to wear, need often to change, after wooden rising head stake wearing and tearing, band film can be caused during molding, after cast, there will be the defect of rising head loam, drop, adopt the stake of aluminium alloy rising head just to avoid these problems.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
