Description
Известные способы устранени разностенности отливок трудоемки и малопроизводительны .Known methods of eliminating the difference in the thickness of the castings are laborious and inefficient.
По предложенному способу ребра жесткости опоки снабжают фиксаторами, а в верхних знаках стержн выполн ют углублени , в которые при сборке формы ввод т фиксаторы.According to the proposed method, the stiffeners of the flask are provided with latches, and in the upper signs of the rod there are recesses into which the latches are inserted during assembly of the mold.
На фиг. 1 изображена схема формы, собранной по предложенному способу, разрез; на фиг. 2 -то же, вид в плане.FIG. 1 shows a diagram of a form assembled according to the proposed method, a section; in fig. 2 is the same, plan view.
В ребрах жесткости / верхней опоки 2 жестко укрепл ют фиксаторы 3, которые после уплотнени формовочной смеси, например путем нижнего прессовапи , выступаЕОт во внутреннюю полость полуформы 4.In the stiffening ribs / upper flask 2, fixers 3 are rigidly fastened, which, after compaction of the molding sand, for example, by means of a lower press head, projecting EO into the internal cavity of the mold half 4.
При изготовлении стержн 5 в его торцовых верхних знаках 6 выполн ют овальные углублени .In the manufacture of the rod 5 in its face upper marks 6, oval grooves are made.
При сборке формы выступающие части фиксаторов ввод т в углублени знаков, выправл установленный стержень и надежно его фиксируют.When assembling the form, the protruding parts of the retainers are inserted into the recesses of the signs, straightening the installed rod and fix it securely.
Предмет изобретени Subject invention
Способ устранени разностенности отливок , например секционных отопительных радиаторов , получаемых в земл ных формах со стержнем, отличающийс тем, что, с целью упрощени процесса сборки формы, ребра жесткости опоки снабжены фиксаторами, а в верхних стержн выполнены углублени , в которые при сборке формы ввод т фиксаторы .A method for eliminating the difference in the thickness of castings, for example, sectional heating radiators, produced in earth forms with a rod, characterized in that, in order to simplify the mold assembly process, the stiffeners of the flask are provided with retainers, and in the upper shaft there are made recesses clamps.
