Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of cast gate cutting injection moulding mould.
Background technology
A kind of processing method of using when injection mo(u)lding is some complex-shaped parts of batch production.Specifically refer to the material melting that is heated to inject die cavity by high pressure, after cooling curing, obtain formed products.Existing injection mo(u)lding is applicable to complicated die, but less for some holes, or the problems such as insufficient easily appear filling in thin-wall part, and often there is support in existing injection mold and cannot occur that larger gate vestiges needs manual removal by closed cast gate after producing finished product, and efficiency is low.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of cast gate cutting injection moulding mould, the cast gate that setting can conveniently be cut off is realized the removing of gate vestiges, by taper tube core and guiding gutter are set, guarantee the good closure of injection moulding pipeline, by being provided with heater, the mobility that guarantees injection moulding liquid in pipe, obstruction pipeline prevents from condensing; Have that unfailing performance is high, compact conformation, without gate vestiges, the advantage such as simple in structure, easy to use, adaptability is good, cheap, at Die & Mould Market, have market prospects widely simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cast gate cutting injection moulding mould is provided, comprise: base, mold, bed die, top board, guide pillar guide pin bushing, injection molding tube, tube core, spring and heater, described base is provided with bed die, on bed die, be provided with mold, top board is arranged on mold top base surrounding and is provided with guide pillar guide pin bushing, described injection molding tube is arranged on mold top, and coaxially arranged with mold central axis, in injection molding tube, be provided with tube core, spring housing is connected on tube core, injection molding tube arranged outside having heaters.
In preferred embodiment of the utility model, described top board central authorities are provided with and keep away a hole, and mold center is provided with cast gate.
In preferred embodiment of the utility model, it is spacing that described tube core middle part is provided with spring, and tube core front end is provided with cut-out head, described cut-out head is back taper, back taper surface is provided with guiding gutter, and back taper end is provided with taper head, and described taper head is obtuse angle.
In preferred embodiment of the utility model, 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 that cuts off a back taper.
In preferred embodiment of the utility model, the back taper maximum cross-section area that described back taper cuts off head is identical with injection molding tube maximum cross-section area.
The beneficial effects of the utility model are: the cast gate that the setting of the utility model cast gate cutting injection moulding mould can conveniently be cut off is realized the removing of gate vestiges, by taper tube core and guiding gutter are set, guarantee the good closure of injection moulding pipeline, by being provided with heater, the mobility that guarantees injection moulding liquid in pipe, obstruction pipeline prevents from condensing; Have that unfailing performance is high, compact conformation, without gate vestiges, the advantage such as simple in structure, easy to use, adaptability is good, cheap, at Die & Mould Market, have market prospects widely simultaneously.
