Description

Изобретение относитс  к области переработки термопластичных материалов литьем ПОД давлением.This invention relates to the field of processing thermoplastic materials by injection molding.

Известен способ изтотовлени  изделий из термопластов путем формовани  в полости, образованной полуформами и оформл ющими знаками, с последующим охлаждением отформованного издели  на оформл ющих знаках вне формы.There is a known method of making products from thermoplastics by molding in a cavity formed by semi-molds and decorating marks, followed by cooling the molded product on the decorating marks outside of the mold.

Этот способ не позвол ет снизить величпгсу внутренних напр жений, возникающих в центральной части издели  в процессе охлаждени  ето, что снижает прочностные характеристики отформованной детали.This method does not allow to reduce the magnitude of internal stresses arising in the central part of the product during the cooling process, which reduces the strength characteristics of the molded part.

Предложенный способ отличаетс  от известното тем, что оформл ющие знаки перед процессом охлаждени  издели , например фитинга, извлекают из центральной части, оставл   их на патрубках фитинга.The proposed method differs from that in that the marks that are drawn before the process of cooling the product, for example the fitting, are removed from the central part, leaving them on the fitting nozzles.

Это обеспечивает снижение величины внутренних нанр жений в центральной части фитинга при сохранении заданных размеров его патрубков.This ensures a reduction in the size of internal stress in the central part of the fitting while maintaining the specified dimensions of its nozzles.

Способ предусматривает извлечение оформл ющих знаков в различной последовательности .The method involves the extraction of design characters in different sequences.

22

Так, например, можно частично извлекать из центральной части фитинга (тройника) сразу три оформл ющих знака, два или один.For example, it is possible to partially extract three marks from the central part of a fitting (tee), two or one.

На чертеже показан процесс охлаждени  отформованного фитинга 1 (т ройника), когда ОДИН из оформл ющих знаков 2 извлечен из центральной части 3 издели , в то врем  как знаки 4 и 5 наход тс  в сомкнутом состо нии . При этом в результате свободной усадки центральной части 3 тройника осуществл етс  деформаци  ее в радиальном и осевом направлени х, что приводит к снижению внутренних напр женнй в этой части издели .The drawing shows the cooling process of the molded fitting 1 (reel) when one of the indicia 2 is removed from the central part 3 of the product while the signs 4 and 5 are in a closed state. In this case, as a result of the free shrinkage of the central part 3 of the tee, its deformation in the radial and axial directions occurs, which leads to a decrease in the internal stresses in this part of the product.
