Abstract
The utility model discloses a novel needle valve eccentric hot nozzle. The hot nozzle comprises a valve needle, a valve needle sleeve and a runner plate, wherein one end of the valve needle is connected with a cylinder, and the other end of the valve needle penetrates through the runner plate and a hot nozzle body and is contacted with a sprue; the valve needle penetrates through the valve needle sleeve arranged on the hot nozzle body; the bottom of the runner plate is connected with one end of the hot nozzle body; a heating line is arranged on the outer side of the other end of the hot nozzle body; a temperature sensing line is arranged between the hot nozzle body and the heating line; a feed port is formed on the runner plate; and the tail end of the feed port is communicated with an inner cavity of the hot nozzle body. The hot nozzle has the advantages that the hot nozzle has a simple structure and is low in production cost; the adverse phenomena that plastic is leaked, a product has burrs and the like because the valve needle sleeve moves and the valve needle is blocked or bent are effectively avoided; and production benefits are greatly improved, and the production cost is effectively reduced.
Description
Technical field
The utility model relates to a kind of injection moulding to be chewed with heat, and the eccentric heat of particularly a kind of novel needle valve is chewed.
Background technology
Existing traditional heat is chewed, and the needle guide pin bushing is positioned on the runner plate, because runner plate expands with heat and contract with cold, can cause the needle cover to walk, thereby cause needle stuck or crooked, causes leaking glue, and product produces bad phenomenon such as burr, has a strong impact on productivity effect.
Summary of the invention
To the shortcoming that existing heat is chewed, the utility model provides the eccentric heat of a kind of novel needle valve to chew.
To achieve these goals, the measure taked of the utility model:
The eccentric heat of a kind of novel needle valve is chewed, and comprises needle, needle cover, runner plate, and needle one end is connected with cylinder, and the needle other end passes runner plate, heat and chews body and contact with cast gate; Simultaneously, needle passes and is arranged at heat and chews the needle cover on the body; The runner plate bottom is chewed body one end with heat and is connected; Heat is chewed body other end arranged outside has heater wire; Heat is chewed between body and heater wire and is provided with temp.-sensing wire; Meanwhile, runner plate is provided with charging aperture, and the terminal and hot inner chamber body of chewing body of charging aperture is connected.
The beneficial effect of the utility model: simple in structure, production cost is low; Effectively the needle cover walks, causes stuck or crooked causing of causing of needle to leak glue, product produces bad phenomenon such as burr because of causing in solution; Improve productivity effect greatly, effectively reduce production costs.

Fig. 2, the cross-section structure and the cast gate of the utility model are closed sketch map.
The specific embodiment
The eccentric heat of a kind of novel needle valve is chewed, and is as shown in Figure 1, comprises needle 1, needle cover 2, runner plate 3, and needle 1 one ends are connected with cylinder, and needle 1 other end passes runner plate 3, heat and chews body 4 and contact with cast gate 8; Simultaneously, needle 1 passes and is arranged at heat and chews the needle cover 2 on the body 4; Runner plate 3 bottoms are chewed body 4 one ends with heat and are connected; Heat is chewed body 4 other end arranged outside has heater wire 5; Heat chews body 4 and 5 of heater wires are provided with temp.-sensing wire 6; Meanwhile, runner plate 3 is provided with charging aperture 9, and charging aperture 9 terminal and hot inner chamber body of chewing body 4 are connected.In the actual implementation process of patent; After the plastics of fusion penetrate in the injection machine; Get into the inner chamber that heat is chewed body 4 through runner plate 3 by charging aperture 9 places; Because heat is chewed body 4 under the accurate temperature-sensitive effect of the continuous heating of heater wire 5 and temp.-sensing wire 6, but make the plastic cement of fusion keep best injection moulding state; When injection moulding began, owing to make that under the effect of cylinder needle 1 moves upward, cast gate 8 is opened, and was as shown in Figure 2, and plastic cement gets into die cavity; When injection moulding was accomplished, under the effect of cylinder, needle 1 moved downward, and cast gate B sealing is as shown in Figure 3.This patent is because needle cover 2 is positioned at heat chews on the body 4, and the influence that not expanded with heat and contract with cold by runner plate 3 then efficiently solves and causes the needle cover to walk, thereby causes needle stuck or crooked, causes leaking glue, and product produces bad problems such as burr.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in this area.
