Abstract

A kind of writing implement, polychrome watercolor pencil and manufacture method.Pen core more than 3 or 3 embedded in the through hole of written mould by designing requirement be cast into integral body with the injection machine injected plastic resin.The rolled core that tight lid is isolated lid is fixed in the penholder of band pad, nib through revising embeds the pen neck end at penholder, pen core passes on the pad and draws ink in the through hole insertion rolled core, seals in case colour mixture is adorned chromosphere at pen neck end with binding agent between rear seal-cover and penholder and pen core and pad.A plurality of pen cores are combined in the nib can write different colours respectively, can colour contamination during placement, colour mixture yet, suitable for mechanization is produced in batches, is used for that the art designing draws a picture, the teacher gives lectures.

Description

Polychrome watercolor pencil and manufacture method

The present invention relates to a kind of writing implement, polychrome watercolor pencil and manufacture method.

Existing commercially available watercolor pencil mostly is monochromatic, and number of patent application 87103509 " pastel ", 87107887 " multicolored bundled felt-tip pens " they all be with each monochromatic system in combination on body and nib, utilize of all kinds writing or many primary colors colorant match one-tenth colour, but in fact these pens all can't be implemented, unstable properties can not mechanization production.Even do not writing when placing all colour contamination, colour mixture and can't use mutually between them.

The object of the present invention is to provide a kind of polychrome watercolor pencil and manufacture method, only just can write multiple color with a nib, penholder, the suitable for mechanization production in enormous quantities can colour contamination during placement, colour mixture yet.

The present invention is achieved in that the pen core more than 3 or 3, embed in the through hole of written mould by designing requirement, use the injection machine injected plastic resin, with pen core, nib is cast into holistic written base, be placed in the penholder that is fixed with pad tightly being stamped the rolled core of isolating lid, the nib base embeds in penholder after written straightener correction is good, the tail end of pen core is passed on the pad through hole to be inserted in the rolled core and draws ink, the tail end of penholder is rear seal-cover fixedly, with the binding agent sealing, nib and penholder seam close-fitting are adorned chromosphere at pen neck end between rear seal-cover and penholder and pen core and pad, put the pen cap, the polychrome watercolor pencil just has been assembled into.

Below in conjunction with accompanying drawing embodiments of the invention are further described:

Penholder (6), (6) ' by the injection machine single injection-molded, the cross section can be circle or triangle, the centre have the Y type ,+the type isolation bar shown in Fig. 2,3, also can be other shape.Pen core (3) has 3 or 4 shown in Fig. 2,4, also can be many, decide as required, chromosphere, isolation lid, pad and penholder shape are complementary, to chromosphere (4) is annular, isolates lid (8) for the cylinder of three annulus is arranged, and pad (5) is for having fixedly 3 through holes of pen core (3) on the circle, it is fixed on the inwall of penholder (6) Shang neck, and rear seal-cover (9) is for there being the cylinder of two annular grooves.The pen cap (2) is two concentric column chambeies, Chu Moguan be rolled core (7), (7) ', be various different colours.

Make mould by nib (1) design shape requirement, make three or four apertures leaving in the mold cavity by the certain arrangement and the big or small degree of depth, distance is 0.2～1mm between each aperture, can make a plurality of nibs simultaneously in one pair of mould.

3 or 4 pen cores (3) are inserted respectively in the aperture in nib (1) mold cavity, utilize vertical or horizontal injection press with the mould matched moulds, injected plastic resin is in shaping mold cavity, make the moulding nib base of mutual isolation by pressurize, die sinking, write the contact with written straightener by writing requirement correction, the end face periphery and the centre of nib (1) are inside arcs of recesses, increase the written portion and the effect of storage China ink of nib, just make the nib (1) of a whole band pen core (3), the same injection mo(u)lding with prior art of other parts does not repeat.

With the rolled core (7) of 3 kinds or 4 kinds different colours, (7) ' respectively from penholder (6), (6) ' afterbody insert the Y type or+the type neutral gear in, rolled core (7), (7) ' an end tightly cover isolate lid (8), (8) ', in case rolled core (7), (7) ' in ink pour out.To insert in the neck of penholder (6), (6) ' lower end with the nib of pen core again, and make the afterbody of 3 or 4 pen cores (3) pass through hole on the pad (5) respectively, insert each rolled core (7), (7) ' in, draw ink.With rear seal-cover (9) tightly be embedded in penholder (6), (6) ' tail end, be close to isolate lid (8), (8) '., will be nested into the interface of a neck from nib (1) to chromosphere (4), and fix with pattern or color showing the colour code on the chromosphere (4), and make the colour code of color of the same race and the writing position of pen core (3) differ 180 ° with binding agent.Rear seal-cover (9) and penholder (6), (6) ', with the binding agent sealing, in case ink blending, nib (1) and penholder (6), (6) ' use the seam close-fitting put the pen cap (2) again between pen core (3) and pad (5), and a polychrome watercolor pencil just has been made into.

Nib (1) is produced and also can be utilized another preparation method to make, with the written frame of mold injection molding by designing requirement, in written frame, leave the through hole more than 3 or 3, again corresponding pen core (3) more than 3 or 3 is dipped in and be fixed into holistic written base in the through hole of resin glue close-fitting in written frame, other assembly method and step and above-mentioned just the same do not repeat.

As required the pen cap (2) is taken off in two annular grooves that are placed on rear seal-cover (9) during use, as long as with required colour code, for example red, be held between thumb and forefinger, then nib is just write out corresponding redness, if need blueness, then blue scale is held between thumb and forefinger, then nib is just write out corresponding blueness, and is consistent with colour code.

The present invention is compared with prior art: the present invention adopts the pen core more than 3 or 3 inserted by the method with the injection moulding principle shot moulding of inserts in the shaping mold cavity of certain arrangement to make nib, Make mutually isolation between each pen core, pen core leads to respectively the middle ink of drawing of ink storage pipe (rolled core) separately, and the imagination that makes a nib can write multiple color becomes a reality. And energy mechanization production in enormous quantities, properties of product are stable, can colour contamination during placement yet, colour mixture, if suitably adjust the distance between pen core in the mould, make its spacing when narrowing down to a certain degree, the different colours pen core is isolated mutually, and when write angle when being between two looks by two kinds of inks rest on the paper with the moment that is absorbed by paper mutually colour mixture become colour to reach secondary color. Pair chromosphere easy to use and flexible is arranged on the penholder, and this Multi-colour pen can be drawn a picture for the art worker, the teacher is in the blackboard teaching and do the reading note use.
