Abstract

"MOLDE COMPACTO DE ATIVAçãO POR PLACAS DESLIZANTES". A presente invenção supera pelo menos algumas das desvantagens da arte anterior ao fornecer um dispositivo de moldagem que tem um mecanismo deslizante que é mais compacto que os mecanismos deslizantes convencionais, não produz obstruções entre as placas abertas do molde, elimina a necessidade por retentores deslizantes e não depende da abertura e fechamento do molde para a ativação; de acordo com a presente invenção, o dispositivo de moldagem inclui no mínimo duas placas de molde que preferivelmente levam uma pluralidade de machos de molde e cavidades de molde conjugadas, que formam uma pluralidade de moldes; cada molde tem um par de elementos de molde lateralmente movíveis os quais são movíveis em direção a e para longe um do outro; os elementos de molde de cada molde estão montados em um par de placas deslizantes posicionadas uma em cada lado do molde; o mecanismo para mover os elementos de molde entre suas posições internas e externas inclui uma cremalheira de condução alternada que conduz no mínimo um pino; cada pino conduz um par de cremalheiras condutoras que são movíveis em direções opostas; cada uma das cremalheiras sendo conectada a uma das placas deslizantes; desta forma, o movimento da cremalheira condutora resulta em um movimento lateral das placas deslizantes e dos componentes do molde associados para dentro ou para fora em relação ao molde; uma vez que o dispositivo da invenção não utiliza pinos de chifre, o desalinhamento das placas deslizantes durante a abertura e fechamento não constitui um problema, e, portanto os retentores deslizantes não são necessários; o mecanismo deslizante da presente invenção é compacto e é encaixado na placa extratora, longe da linha de divisão do molde; isto reduz o tamanho total do molde e elimina obstruções entre as placas do molde, desta forma reduzindo o risco de contaminação das partes que são extraídas dos moldes; além disso, o mecanismo deslizante não depende da abertura e fechamento do molde para ativação já que as cremalheiras condutoras são preferivelmente conduzidas por um cilindro pneumático depois que o molde é aberto e retraídas antes que este seja fechado, desta forma permitindo um tempo de ciclo de molde mais curto."COMPACT SLIDING PLATE ACTIVATION TEMPLATE". The present invention overcomes at least some of the disadvantages of the prior art by providing a molding device that has a sliding mechanism that is more compact than conventional sliding mechanisms, does not produce obstructions between open mold plates, eliminates the need for sliding retainers and It does not depend on mold opening and closing for activation; According to the present invention, the molding device includes at least two mold plates which preferably carry a plurality of mold cores and conjugated mold cavities, which form a plurality of molds; each mold has a pair of laterally movable mold elements which are movable towards and away from each other; the mold elements of each mold are mounted on a pair of sliding plates positioned on either side of the mold; the mechanism for moving the mold elements between their internal and external positions includes an alternating driving rack that drives at least one pin; each pin drives a pair of conductive racks that are movable in opposite directions; each of the racks being connected to one of the sliding plates; thus, movement of the conductive rack results in lateral movement of the sliding plates and associated mold components in or out relative to the mold; Since the device of the invention does not use horn pins, misalignment of the sliding plates during opening and closing is not a problem, and therefore sliding retainers are not required; the sliding mechanism of the present invention is compact and is fitted to the extractor plate away from the mold division line; This reduces the overall size of the mold and eliminates obstructions between the mold plates, thereby reducing the risk of contamination of parts that are extracted from the molds. furthermore, the sliding mechanism does not depend on the opening and closing of the mold for activation as the conductive racks are preferably driven by a pneumatic cylinder after the mold is opened and retracted before it is closed, thus allowing a cycle time of Shorter mold.
