Abstract
The invention discloses a multifunctional valve needle sleeve which is connected between a nozzle and a flow distribution plate. The multifunctional valve needle sleeve comprises a valve needle sleeve body, and a valve needle sleeve boss which is arranged in the middle of the upper surface of the valve needle sleeve body; heating wires are arranged around the sidewall of the valve needle sleeve body; a temperature sensing wire is arranged in the valve needle sleeve body; a hole which is communicated with the valve needle sleeve body is formed in the valve needle sleeve boss to position a valve needle; a heating block is connected to the upper part of the flow distribution plate. With the adoption of the multifunctional valve needle sleeve, the heating block is used for heating the flow distribution plate in a hot runner system to ensure uniform heating temperature of the flow distribution plate, and the problem that a traditional valve needle sleeve cannot be mounted on the flow distribution plate can be solved.
Description
Technical field
The present invention 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.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of multifunction valve needle guard is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention 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 invention has the beneficial effects as follows:
The present invention 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 solution of the present invention, in order to better understand technological means of the present invention, 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 invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.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 present invention 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 the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
