Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of Novel injection mold.
Background technology
Injection forming mold, plastics are melted by heating in the heating cylinder of injection machine first, then under the promotion of screw in injection molding machine or piston, running gate system through nozzle and mould enters mold cavity, finally sclerosis sizing in die cavity, Here it is injection molding simple procedure, and injection mo(u)lding mould used is just injection forming mold. Injection mold is mainly used in the moulding of thermoplastic articles, is all to inject high pressure sizing material by injection moulding runner, during still due to injection moulding runner pan feeding, can the junction of injection moulding runner and die cavity be produced and be impacted, and easily cause plastic finished product to have mark.
Utility model content
For solving the above problems, the utility model provides a kind of Novel injection mold, can avoid plastic finished product to produce mark.
Technical solution adopted in the utility model is: a kind of injection mold, comprises front cavity and rear cavity; Front cavity is located at rear cavity top, with matched moulds; In rear cavity, be provided with die cavity, with shaped article; This kind of injection mold also comprises injection structure, injection structure comprises injection moulding regrinding, injection moulding sprue and injection moulding runner, and injection moulding regrinding is the entrance of injection moulding sprue, and injection moulding sprue is communicated with injection moulding runner, injection moulding runner is communicated with die cavity, so that die cavity is carried out to injection mo(u)lding; Injection moulding runner tail end is V font runner, and V font runner connects die cavity, and the V font runner one end being connected with die cavity is taper road.
In technique scheme, V font runner axial cross section is flat, when high pressure sizing material process, can spread to both sides, reduces straight line impulse force.
In technique scheme, injection moulding runner is provided with screw valve, regulates the injection moulding flow of injection moulding runner, can not cause injection moulding excessive, makes plastic finished product be difficult for producing mark.
In technique scheme, screw valve and injection moulding runner are fixed by screw thread, are easy to the flow that passes through of set screw valve.
In technique scheme, every injection moulding runner is all provided with screw valve, to regulate the injection moulding flow of every injection moulding runner.
In technique scheme, cast sprue is that bellmouth and bottom end opening diameter are greater than top, on cast sprue bottom end opening madial wall, is provided with buffer stopper, and injection moulding regrinding and cast sprue and front cavity coaxially arrange; Buffer stopper makes injection moulding flow velocity mild, effectively slows down high pressure sizing material injection moulding runner and die cavity are produced to impact, makes plastic finished product be difficult for producing mark.
In technique scheme, on the bottom end opening madial wall of described cast sprue, be symmetrically arranged with multiple buffer stoppers, strengthen slowing down effect, make injection moulding flow velocity mild, more effectively slow down high pressure sizing material injection moulding runner and die cavity are produced to impact, make plastic finished product be difficult for producing mark.
In technique scheme, described buffer stopper outer surface is uniformly distributed multiple protruding particles, strengthens slowing down effect, makes injection moulding flow velocity mild, more effectively slows down high pressure sizing material injection moulding runner and die cavity are produced to impact, makes plastic finished product be difficult for producing mark.
In technique scheme, described buffer stopper is 45～60 degree with cast sprue bottom end opening madial wall and arranges, and slows down effectively, makes injection moulding flow velocity mild, more effectively slow down high pressure sizing material injection moulding runner and die cavity are produced to impact, make plastic finished product be difficult for producing mark.
The beneficial effects of the utility model are: this kind of Novel injection mold, because injection moulding runner tail end is V font runner, high pressure sizing material can first decline and rise, high pressure sizing material is slowed down, the impact of the junction to injection moulding runner and die cavity while reducing pan feeding, avoid plastic finished product to produce mark, and the V font runner one end being connected with die cavity is taper road, further reduced and plastic.
