Abstract

The invention discloses a water-cooled liquid silica gel screw material tube device. The water-cooled liquid silica gel screw material tube device comprises a primary nozzle, a mother shooting nozzle,a flange and a material tube which are sequentially arranged and provided with a hollow cavity; the water-cooled liquid silica gel screw material tube device further comprises a glue sealing assemblyarranged in a piston cavity of the mother shooting nozzle, wherein the glue sealing component is composed of a glue sealing valve element, a blocking piece and two piston structures which are formedby two valve element fixing seats arranged on the two sides of the baffle plate respectively; and the glue sealing valve element and the blocking piece fixed on the glue sealing valve element can moveleft and right relative to the two valve element fixing seats in the piston cavity under the action of an air source so as to open or close the inner opening of the nozzle to inject glue. According to the water-cooled liquid silica gel screw material pipe device, the pneumatic or hydraulic-action glue sealing device is additionally arranged in the primary nozzle, so that the problem that a waterport is prone to overflow is solved, and the problem that silica gel at the opening port of the nozzle is easily solidified at the water port of a mold is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and relates to a screw injection molding machine, in particular to a water-cooled liquid silicone screw material tube device. Background technique [0002] Nowadays, the injection molding industry is mainly divided into two categories, one is thermoplastics and the other is thermosetting plastics. Thermoplastics are the most common and most widely used. There is also a more widely used type of thermosetting plastics, and the popular name is silica gel. Silicone products are widely used in the baby product industry and medical industry. Silicone products have many characteristics that other plastics do not have, such as non-toxic, transparent, and high temperature resistance. [0003] At present, the requirements for silicone molding technology are gradually getting higher and higher. Generally, there are A glue and B glue for silicone molding. When the two glues are stored alone, they ...
