Abstract

Perfeccionamientos en las máquinas de moldeo por inyección, y más particularmente en las máquinas de moldeo por inyección de accionamiento manual, caracterizados porque la máquina comprende: (a) una base (b) un cilindro calefactor montado en dicha base y dotado de una cámara, teniendo dicho cilindro calefactor en un extremo una boquilla de descarga con un orificio y un émbolo susceptible de penetrar en dicha cámara hacia dicha boquilla de descarga; (c) un portamoldes soportado por dicha base y dotado de un molde en uno de sus extremos, incluyendo dicho molde elementos primero y segundo de molde que proporcionan conjuntamente una cavidad de molde entre los mismos, teniendo uno de dichos elementos primero y segundo de molde un bebedero que comunica con dicha cavidad de molde y siendo separable del otro, siendo pivotable dicho portamoldes entre una primera posición en la que dicho molde está en contacto con dicha boquilla de descarga con dicho bebedero en comunicación con dicho orificio y unasegunda posición en la que dicho molde está separado de dicha boquilla de descarga; y (d) medios en dicha base para bloquear dicho portamoldes en dicha primera posición.
