Straight through type hot nozzle assembly for high glass fibers and high carbon fibers

Abstract

The invention discloses a straight through type hot nozzle assembly for high glass fibers and high carbon fibers. The straight through type hot nozzle assembly comprises a second hot nozzle body, a straight through core and a second mold core plate, wherein a second core cover is arranged on the outer portion of the straight through core in a sleeved manner, the middle portion of the second hot nozzle body is provided with a second through hole, the straight through core is arranged at the end portion of the second through hole, the middle portion of the straight through core is provided witha third through hole, the third through hole is communicated to the second through hole, the second mold core plate is provided with a second gate, the outer portion of the second gate is provided with a third concave groove, the head portion of the straight through core is aligned to the second gate, and the outer wall of the second core cover and the inner wall of the third concave groove are matched to form a sealing glue. According to the present invention, with the straight through type hot nozzle assembly, the high-temperature plastic has low flowing resistance, the filling is rapid, theproduct surface has uniform color, the product does not have fusion, heat loss does not exist, the core temperature is stable, the molding temperature is low compared to the torpedo core, the problems of no glue generation, slow glue generation and plastic carbonization are not easily generated, and the stability of the molded product is good.

Description

technical field [0001] The invention relates to an improvement of a hot nozzle assembly, in particular to a kind of high-temperature plastic with small flow resistance, small injection pressure loss, fast filling speed, uniform product surface color, no weld line; at the same time, there is no heat loss, and the core temperature is stable. The molding temperature is lower than that of the torpedo core, and it is not easy to have no glue, slow glue, plastic carbonization, and the stability of the molded product is good. High glass fiber and high carbon fiber straight-through hot nozzle assembly. Background technique [0002] as attached figure 1 The hot nozzle assembly shown in the prior art includes a first hot nozzle body 1, a torpedo core 2 and a first mold core plate 5; the outer sheath of the torpedo core 2 is provided with a first core sleeve 3; The first core cover 3 is covered with a first core cover 4; the middle part of the first nozzle body 1 is provided with a fi...
