Abstract
The utility model discloses a kind of multifunction valve needle guard, be connected between nozzle and flow distribution plate, comprise the valve needle cover boss arranged in the middle part of valve needle cover body and valve needle cover body upper surface, described valve needle cover body lateral wall circumference is provided with heater strip, being provided with temp.-sensing wire in valve needle cover body, described valve needle cover boss offering the hole that is communicated with described valve needle cover body for arranging needle; Described flow distribution plate top is connected with heat block.The utility model can solve in TOP-TIP, heats flow distribution plate with heat block, ensures that flow distribution plate heating-up temperature is even, solves traditional valve needle cover and cannot be arranged on problem on flow distribution plate.
Description
Technical field
The utility model relates to hot runner mould, injection molding art, in particular to a kind of multifunction valve needle guard.
Background technology
Valve needle cover is applied in needle valve type hot runner system.Along with the development of TOP-TIP, valve needle cover is generally applied in TOP-TIP, and the valve needle cover of prior art has following defect: in TOP-TIP, and temperature is not easy to control and adds to vulcanize evenly, and traditional valve needle cover cannot be arranged on flow distribution plate.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of multifunction valve needle guard.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of multifunction valve needle guard, be connected between nozzle and flow distribution plate, comprise the valve needle cover boss arranged in the middle part of valve needle cover body and valve needle cover body upper surface, described valve needle cover body lateral wall circumference is provided with heater strip, being provided with temp.-sensing wire in valve needle cover body, described valve needle cover boss offering the hole that is communicated with described valve needle cover body for arranging needle; Described flow distribution plate top is connected with heat block.
Further, described valve needle cover body upper surface offers the hole be communicated with described flow distribution plate.
The beneficial effects of the utility model are:
The utility model can solve in TOP-TIP, heats flow distribution plate with heat block, ensures that flow distribution plate heating-up temperature is even, solves traditional valve needle cover and cannot be arranged on problem on flow distribution plate.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is multifunction valve needle guard annexation schematic diagram;
Fig. 2 is multifunction valve needle guard overall structure schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, Fig. 2, a kind of multifunction valve needle guard, be connected between nozzle 2 and flow distribution plate 4, comprise the valve needle cover boss 31 of valve needle cover body 3 and the setting of valve needle cover body 3 upper surface middle part, described valve needle cover body 3 lateral wall circumference is provided with heater strip 32, being provided with temp.-sensing wire 33 in valve needle cover body 3, described valve needle cover boss 31 offering the hole that is communicated with described valve needle cover body 3 for arranging needle 1; Described flow distribution plate 4 top is connected with heat block 5.Described valve needle cover body 3 upper surface offers the hole be communicated with described flow distribution plate 4.
Needle 1 slides up and down in this valve needle cover body 3, and valve needle cover boss 31 play the guiding role.Because valve needle cover body 3 has certain thickness, must be heated by heater strip 32, ensure homogeneous temperature.And measured the temperature of this valve needle cover body 3 by temp.-sensing wire 33, thus control valve needle guard body temperature does not exceed setting range.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
