Abstract

"PROCESSO PARA A REALIZAçãO E A COLOCAçãO DE UM INVóLUCRO EXTERNO FEITO DE ELASTÈMERO AO NìVEL DA PERIFERIA DE UM CORPO ALONGADO, E, DE UM INVóLUCRO EXTERNO ISOLANTE AO NìVEL DE UM ISOLADOR COMPóSITO ATRAVéS DE MOLDAGEM POR COMPRESSãO". Esse processo de moldagem por compressão consiste: em realizar dois esboços, cuja forma corresponde à distribuição de matéria do invólucro em torno do corpo; em posicionar um dos ditos esboços no seio da impressão fêmea (14) de uma unidade de moldagem inferior (11), a dita impressão correspondendo à forma a conferir ao invólucro; em posicionar acima da dita unidade inferior assim munida do esboço, uma placa ou grade intermediária (19), que define em volume a forma externa do corpo ou de parte desse último, ao nível de suas duas faces principais; em posicionar sobre a face superior da grade ao nível do volume ou saliência o segundo dos ditos esboços; em fechar o molde, a dita unidade superior desse último sendo também munida de uma impressão fêmea (16), e isso durante um tempo suficiente para induzir a realização de duas meias carcaças ou pré-formas, destinadas a constituir no final o invólucro externo do corpo; em abrir o molde e em retirar a placa ou grande intermediária; em posicionar ao nível da impressão inferior da unidade inferior do molde o corpo, a dita impressão inferior estando munida da meia carcaça inferior, que desempenha nesse caso a função de órgão de centragem do corpo; em fechar de novo o molde durante o tempo necessário para a reticulação ou vulcanização do material constitutivo do invólucro e conseq³entemente, para a junção das duas meias carcaças realizadas por ocasião do precedente fechamento do molde, a fim de chegar a um invólucro contínuo; em abrir o molde no final da reticulação ou vulcanização, e depois em retirar o corpo então munido totalmente ou parcialmente do invólucro externo (5)."PROCESS FOR CARRYING OUT AND PLACING AN EXTERNAL HOUSING MADE OF ELASTOMER AT THE LEVEL OF THE OUTSIDE OF A ELONGED BODY, AND OF AN EXAMINING EXTERNAL HOUSING AT THE LEVEL OF A COMPOSITE INSULATOR THROUGH COMPRESSION MOLDING". This compression molding process consists of: making two sketches, the shape of which corresponds to the distribution of matter in the wrapper around the body; in positioning one of said sketches within the female print (14) of a lower molding unit (11), said print corresponding to the shape to be given to the wrapper; in positioning above said lower unit thus equipped with the outline, an intermediate plate or grid (19), which defines in volume the external shape of the body or part of the latter, at the level of its two main faces; in positioning the second of said sketches on the upper face of the grid at the level of the volume or projection; in closing the mold, said upper unit of the latter being also provided with a female impression (16), and this for a time sufficient to induce the realization of two half-carcasses or preforms, destined to constitute in the end the external casing of the body; opening the mold and removing the plate or large intermediate; in positioning the body at the level of the lower impression of the lower mold unit, said lower impression being provided with the lower half housing, which in this case acts as the body's centering member; to close the mold again during the time necessary for the crosslinking or vulcanization of the material constituting the shell and, consequently, for the joining of the two half-carcasses made during the previous closing of the mold, in order to arrive at a continuous shell; to open the mold at the end of the cross-linking or vulcanization, and then to remove the body, then fully or partially provided with the outer shell (5).
