Abstract
A mixed-color spray nozzle of an injection molding machine comprises a spray nozzle body, a spray nozzle filtering core and a small spray nozzle; the spray nozzle body is in threaded connection with the small spray nozzle, a cavity is formed inside, the spray nozzle filtering core is mounted in the cavity, two ends of the spray nozzle filtering core are in contact with inner hole conical surfaces of the spray nozzle body and the small spray nozzle, a plurality of spaced main flow channels are arranged on the spray nozzle filtering core in the axial direction, one end of each main flow channel is communicated, the other end thereof is sealed, and the sealed ends and the communicated ends are arranged alternatively, and the adjacent main flow channels are communicated through a plurality of small flow channels in the circumferential direction. The utility model has the advantages that firstly, the mixed-color spray nozzle achieves the effect of mixing colors, improves the color matching stability, eliminates the generated problems such as color strips or toner clouds due to uneven mixture of the colors, can save the dose of color types and toners, also can ensure that the gloss index of the surface of the injection molding component is obviously ascended, improves the smoothness at the periphery of the surface of the injection molding component and improves the entire strength of the injection molding component; secondly, the utility model can shorten the injection molding period, improve the production efficiency and reduce the manufacturing cost through adopting the mixed-color spray nozzle; and thirdly, the disassembly, the assembly and the cleaning are convenient by adopting the three-segment structure.
Description
Technical field
The utility model relates to a kind of part of injection machine, particularly a kind of nozzle that the colour mixture effect is arranged of injection machine.
Background technology
Painted is very important in a plastic processing process step, the purpose of coloring plastic is not only in order to make goods bright and colourful, improves its commercial value, also possesses some other important function, for example, distinguish the different functions of use of goods and performance etc. with different colors.
Existing injection machine colour mixture can improve the melting effect of screw rod so mainly by injection machine is suitably applied back pressure, helps dispersing of pigments, but the side effect that applies back pressure is to make production of articles cycle lengthening.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and color mixing nozzle that a kind of injection machine is provided, makes it not adjust the colour mixture effect that improves goods down in original Shooting Technique, shortens injection cycle, reduces substandard products.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The color mixing nozzle of injection machine, comprise nozzle body, nozzle filter core, small nozzle, described nozzle body is threaded with small nozzle, the inner cavity that forms, the nozzle filter core is installed in this cavity, and nozzle filter core two ends and nozzle body and the small nozzle endoporus conical surface are fitted, and the sprue at axial some intervals is arranged on the nozzle filter core, sprue one end is logical, an end seals and seal and be communicated with the interval is provided with, and its adjacent sprue communicates by many small flow channels of circumferencial direction.
Above-mentioned sprue evenly distributes on circumference.
The sectional area of the small flow channels of said nozzle filter core circumferencial direction looks injection speed is corresponding to be chosen, with 3-5mm
2Be advisable.
Above-mentioned color mixing nozzle is installed on the front barrel of injection machine by the screw thread of nozzle body.
During the injection machine injection, the plastic cement melt enters nozzle body by front barrel and arrives the nozzle filter core again, shaft orientation flowing channel by the nozzle filter core is divided into some ramuscules to melt, merge into some ramuscules again after flowing through the tiny runner on the circumference of nozzle filter core again, melt continues to flow to small nozzle and converges one, and melt is carried out colour mixture.Design axial sprue and circumferencial direction fluting small flow channels, both communicate.The plastic cement melt enters from the unimpeded side of sprue, flows through the circumferencial direction small flow channels and is summarized in the outflow of side sprue.Closed in one minute one of the plastic cement melt-flow, and promoted toner, the diffusion of look kind in the plastic cement melt reached the effect of colour mixture.
Compared with prior art, advantage of the present utility model is:
1, passes through color mixing nozzle, closed in one minute one of the plastic cement melt-flow, promoted toner, look kind in the plastic cement melt diffusion and mix, reached the effect of colour mixture, improved color matching stability, eliminated because of mixing look kind " striped " that inequality produces or the toner problem that " clouds up ", and can save look kind, toner consumption, the moulding surface gloss is obviously risen, and the moulding surface is surrounded and watched smoothness and is improved; Avoid plastic cement melt " overheated " degraded, the moulding bulk strength is improved.
2, by color mixing nozzle, can shorten injection cycle, enhance productivity, reduce production costs.
3, adopt three stage structure, dismounting is cleaned convenient.
Description of drawings
Fig. 1 is the assembling stereogram of the utility model embodiment.
Fig. 2 is the filter core stereogram of the utility model embodiment.
Fig. 3 is the 2 d plane picture of the utility model embodiment filter core.
The specific embodiment
Below in conjunction with accompanying drawing embodiment this is used novel do progress one detailed description.
As shown in Figure 1, the color mixing nozzle of injection machine, comprise nozzle body 2, nozzle filter core 3, small nozzle 1, the nozzle filter core is installed within nozzle body 2 and the small nozzle 1, the two ends conical surface of nozzle filter core 3 respectively with the cone match of nozzle body, small nozzle endoporus, when small nozzle screwed, the nozzle filter core was locked in nozzle body inside, nozzle filter core external diameter and nozzle body internal diameter matched in clearance.
The nozzle filter core is seen Fig. 2, depicted nozzle filter core 3 has six sprues 31 and evenly distributes on circumference, and the sealing of sprue one end, other end connection and sealing and connection are provided with at interval, forms the distribution that an end three seals tee joints thus, 31 of sprues are communicated with by some circumferential grooves 32, see Fig. 3.
During the injection machine injection moulding, see Fig. 1, the plastic cement melt flows to nozzle body from the front barrel of injection machine, melt is shunted through the nozzle filter core, three sprues of flow nozzle filter core, melt respectively several small flow channels by both sides gather respectively with the side sprue in, melt flows out sprue under injection pressure, inject mould by the small nozzle hole.Above-mentioned mating surface must not leave the dead angle, avoids buildup.
Claims (3)
1, the color mixing nozzle of injection machine, it is characterized in that: comprise nozzle body, nozzle filter core, small nozzle, described nozzle body is threaded with small nozzle, the inner cavity that forms, the nozzle filter core is installed in this cavity, and nozzle filter core two ends and nozzle body and the small nozzle endoporus conical surface are fitted, and the sprue at axial some intervals is arranged on the nozzle filter core, sprue one end is logical, an end seals and seal and be communicated with the interval is provided with, and its adjacent sprue communicates by many small flow channels of circumferencial direction.
