Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of cast gate cutting injection moulding mould.
Background technology
A kind of processing method that injection mo(u)lding is used when being and produce some complex-shaped parts in batches.Refer specifically to by high pressure, the material melted that is heated is injected die cavity, after cooled solidification, obtain formed products.Existing injection mo(u)lding is applicable to complicated die, but it is less for a some holes, or easily there are filling the problems such as insufficient in thin-wall part, and existing injection mold often exists support and cannot close the cast gate manual removal of the bigger gate vestiges needs of appearance after producing finished product, and efficiency is low.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of cast gate cutting injection moulding mould, the cast gate that setting can conveniently be cut off realizes the removing of gate vestiges, by arranging taper tube core and guiding gutter, ensure the good closure of injection molded tube, it is provided by heater, ensure the mobility of injection liquid in pipe, prevent from condensing and block pipeline；Have unfailing performance height, compact conformation, without gate vestiges, simple in construction, easy to use, adaptability good, the advantage such as cheap, has market prospect widely at Die & Mould Market simultaneously.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of cast gate cutting injection moulding mould, including: base, mold, lower mold, top board, guide pillar guide pin bushing, injection molding tube, tube core, spring and heater, described base is provided with lower mold, mold it is provided with in lower mold, top board is arranged on base surrounding above mold and is provided with guide pillar guide pin bushing, described injection molding tube is arranged on above mold, and arrange with mold central axis coaxial, tube core it is provided with in injection molding tube, spring housing is connected on tube core, heater it is provided with outside injection molding tube.
In a preferred embodiment of the present invention, described ceiling center is provided with keeps away a hole, and mold is provided centrally with cast gate.
In a preferred embodiment of the present invention, being provided with spring retainer in the middle part of described tube core, tube core front end is provided with cut-out head, and described cut-out head is inverted cone, and inverted cone surface configuration has guiding gutter, inverted cone end to be provided with taper head, and described taper head is obtuse angle.
In a preferred embodiment of the present invention, described injection molding tube is copper, and injection molding tube one end is provided with bellmouth, and the cone angle of described bellmouth is less than the cone angle cutting off head inverted cone.
In a preferred embodiment of the present invention, the back taper maximum cross-section area that described inverted cone cuts off head is identical with injection molding tube maximum cross-section area.
The invention has the beneficial effects as follows: cast gate cutting injection moulding mould of the present invention arranges the cast gate that can conveniently cut off and realizes the removing of gate vestiges, by arranging taper tube core and guiding gutter, ensure the good closure of injection molded tube, it is provided by heater, ensure the mobility of injection liquid in pipe, prevent from condensing and block pipeline；Have unfailing performance height, compact conformation, without gate vestiges, simple in construction, easy to use, adaptability good, the advantage such as cheap, has market prospect widely at Die & Mould Market simultaneously.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
