Abstract

"PROCESSO E ARRANJO PARA SUPORTAR AS EXTERMIDADES DE UM FIO DE RESISTêNCIA NA MANUFATURA DE ACESSóRIOS DE TUBO PLáSTICO SOLDáVEIS POR AQUECIMENTO ELéTRICO EM UM MOLDE DE INJEçãO" A invenção refere-se a um processo e a um arranjo para suportar as extermidades de um fio com resistência na fabricação de acessórios de tubo de plástico soldáveis por aquecimento elétrico em um molde de injeção. No processo, um fio com resistência eletricamente aquecido (4) é enrolado em torno do núcleo (1), as extremidades do fio com resistência (4) são conectadas a cavilhas (5, 6), pinos (9, 10) são encaixados em rebaixos (furos) (7, 8) providos no núcleo (1), e as cavilhas (5, 6) são suportadas no núcleo (1) por meio de pinos (9, 10) conectados ao mesmo. De acordo com a invenção, uma bucha guia (11, 12) é disposta em contato com cada pino (9, 10) e a cavilha conectada (5, 6) cada bucha guia (11, 12) é suportada em um recesso ( 13, 14) provido no molde de injeção (2), um atuador elástico tal como uma mola (15, 16) é disposto para atuar em cada bucha guia (11, 12), de modo que sua potência de retenção pressiona a bucha guia, a cavilha e pino para uma posição contra o núcleo (1), a operação de moldagem por injeção é iniciada introduzindo-se a composto de moldagem por injeção em torno do núcleo (1), no espaço de moldagem (3) de um modo conhecido per se, de modo que, conforme o composto de moldagem por injeção alcançar cada pino (9, 10), a pressão do plástico levanta o pino (9, 10), a cavilha (5, 6) e a bucha guia (11, 12) a partir do núcleo (1) contra a energia de retenção do atuador tal como uma mola (15, 16) e após a moldagem por injeção, o núcleo (1) é retirado da manta (2), amanta (2), incluindo as buchas guias (11, 12), é aberta e o acessório acabado é removido do molde de injeção."PROCESS AND ARRANGEMENT TO SUPPORT THE END OF A RESISTANCE WIRE IN THE MANUFACTURE OF ELECTRIC HEATING PLASTIC TUBE ACCESSORIES IN AN INJECTION MOLD" The invention relates to a process and arrangement to support the ends of a wire with resistance in the manufacture of plastic pipe fittings weldable by electric heating in an injection mold. In the process, an electrically heated resistor wire (4) is wrapped around the core (1), the ends of the resistor wire (4) are connected to pegs (5, 6), pins (9, 10) are fitted in recesses (holes) (7, 8) provided in the core (1), and the pins (5, 6) are supported in the core (1) by means of pins (9, 10) connected to it. According to the invention, a guide bushing (11, 12) is arranged in contact with each pin (9, 10) and the connected pin (5, 6) each guide bushing (11, 12) is supported in a recess (13 , 14) provided in the injection mold (2), an elastic actuator such as a spring (15, 16) is arranged to act on each guide bushing (11, 12), so that its holding power presses the guide bushing, the pin and pin to a position against the core (1), the injection molding operation is initiated by introducing the injection molding compound around the core (1), into the molding space (3) in a known manner per se, so that, as the injection molding compound reaches each pin (9, 10), the plastic pressure raises the pin (9, 10), the pin (5, 6) and the guide bushing (11, 12) from the core (1) against the actuator holding energy such as a spring (15, 16) and after injection molding, the core (1) is removed from the mat (2), mat (2), including the The guide bushings (11, 12) are opened and the finished accessory is removed from the injection mold.
