Description
Technical Field
The utility model belongs to the field of mechanical casting, and particularly relates to a die assembly structure for casting of a guide wheel casting before tensioning of an electric shovel.
Background
The manufacturing of the front tightening guide wheel of the electric shovel is to adopt a casting technology to produce a casting blank at first and then to carry out machining. However, because the guide wheel is in a hollow hole shape before the electric shovel is tensioned, the casting production difficulty is high, and particularly, the pouring system is arranged during casting, namely, the matching arrangement of the opposite pouring gate, the transverse pouring gate, the inner pouring gate and the riser is realized, the conventional 4 vertical pouring gates are directly arranged on the casting, and the problem that the thin-wall cracks are formed by cracking the casting due to insufficient pouring is solved at the hole intervals Duan Chang of the guide wheel casting before the electric shovel is tensioned, so that the quality of the casting and the production qualification rate of the casting are seriously influenced.
Disclosure of utility model
The utility model provides a die assembly structure for casting of a front guide wheel casting of an electric shovel, which aims to solve the technical problem that a casting crack is formed by the gap Duan Chang of a pattern hole of the front guide wheel casting of the electric shovel due to insufficient casting.
The utility model adopts the following technical scheme:
The utility model provides a group's mould structure for taut preceding guide pulley foundry goods pouring of electric shovel, includes preceding guide pulley model, preceding guide pulley model upper and lower face symmetry equipartition is provided with the flower hole, and preceding guide pulley model centre is provided with the drum model, drum model top is provided with drum thickening section model, and drum thickening section model is provided with the ingate model along the diametric both sides respectively, is provided with the cross gate model on the ingate model, and cross gate model centre is provided with the vertical sprue model.
The front guide wheel model, the cylinder thickening section model, the inner runner model, the cross runner model and the vertical runner model are sequentially and fixedly connected with one another, so that molten iron flows during casting molding and pouring.
And in the further step, a pouring cup is further arranged at the top of the vertical pouring channel model so that molten iron enters a pouring system when the casting is poured.
When the utility model is implemented, the die assembly structure for the front guide wheel casting of the electric shovel tensioning is manufactured according to the technical scheme of the utility model and is used for casting production. According to the utility model, the cylinder thickening section model is arranged at the top of the cylinder model above the front guide wheel model, so that each part of the front guide wheel casting tensioned by the electric shovel, especially the flower hole spacing section of the front guide wheel casting tensioned by the electric shovel, can be timely fed in the casting process, and sequential solidification is realized. And obtaining qualified casting quality. After the casting is produced, the redundant part of the thickened section of the cylinder at one side of the front guide wheel is processed only when the casting is machined.
The utility model has the following beneficial effects:
The utility model has reasonable structure and convenient implementation. Compared with the conventional mould assembling structure in which 4 vertical pouring channels are arranged on a casting (see fig. 3 and 4) and are directly arranged on the casting, the problem that molten iron cannot be fed to crack the casting to form thin-wall cracks when the flower hole spacing section of the guide wheel casting is poured before the electric shovel is tensioned can be solved, and the quality of the casting and the production qualification rate of the casting can be effectively improved.
