A kind of television rear cover mould
Technical field
This utility model relates to a kind of television rear cover mould, belongs to hardware dies technical field.
Background technology
Currently for traditional panel television rear cover injection mold, in use also existing and be difficult to the demoulding, easily there is the situation at dead angle in perfusion, it would be highly desirable to improve.
Utility model content
The technical problems to be solved in the utility model, is to provide a kind of television rear cover mould, and this mould is beneficial to the product stripping after molding, and does not haves perfusion dead angle.
This utility model is realized by following proposal: a kind of television rear cover mould, it includes upper bolster and die shoe, the lower end of described upper bolster is provided with fixture block, the upper end of described die shoe is provided with the draw-in groove corresponding with described fixture block, described upper bolster and described die shoe are connected by described fixture block and described draw-in groove, television rear cover forming cavity it is provided with between described upper bolster and described die shoe, the surrounding of described television rear cover forming cavity is equipped with antiadhesion barrier, described upper bolster is provided with multiple injected hole, described injected hole is divided into limit injected hole and middle injected hole, described limit injected hole and described middle injected hole are all connected to described television rear cover forming cavity by sprue channel, described die shoe is provided with heat sink, described heat sink is arranged on the lower end of described television rear cover forming cavity.
Described antiadhesion barrier is arranged on lower end and the upper end of described die shoe of described upper bolster.
The diameter of described limit injected hole and middle injected hole is more than the diameter of described sprue channel.
Described middle injected hole is provided with 3.
Described limit injected hole is provided with 6, and is evenly distributed on described upper bolster.
The beneficial effects of the utility model are:
1, this utility model one television rear cover mould is provided with multiple limits material hole and middle material hole so that perfusion does not haves dead angle, it is ensured that the quality of the television rear cover produced;
2, it is equipped with antiadhesion barrier on the die holder up and down of a kind of television rear cover of this utility model mould, can be prevented effectively from antiseized;
3, the die shoe of a kind of television rear cover of this utility model mould is provided with heat sink, can make the television rear cover after molding can quick heat radiating, in order to the demoulding.
Accompanying drawing explanation
Fig. 1 be this utility model a kind of television rear cover mould face cross-sectional view.
Fig. 2 is the plan structure schematic diagram of this utility model a kind of television rear cover mould.
In figure: 1 is upper bolster, 2 is die shoe, and 3 is fixture block, and 4 is draw-in groove, and 5 is television rear cover forming cavity, and 6 is antiadhesion barrier, and 7 is limit injected hole, and 8 is middle injected hole, and 9 is sprue channel, and 10 is heat sink.
Detailed description of the invention
Below in conjunction with Fig. 1-2, this utility model is further illustrated, but this utility model protection domain does not limit to described content.
The most identical parts are presented with like reference characters.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
A kind of television rear cover mould, it includes upper bolster 1 and die shoe 2, the lower end of upper bolster 1 is provided with fixture block 3, the upper end of die shoe 2 is provided with the draw-in groove 4 corresponding with fixture block 3, upper bolster 1 and die shoe 2 are connected by fixture block 3 and draw-in groove 4, television rear cover forming cavity 5 it is provided with between upper bolster 1 and die shoe 2, the surrounding of television rear cover forming cavity 5 is equipped with antiadhesion barrier 6, upper bolster 1 is provided with multiple injected hole, injected hole is divided into limit injected hole 7 and middle injected hole 8, limit injected hole 7 and middle injected hole 8 are all connected to television rear cover forming cavity 5 by sprue channel 9, die shoe 2 is provided with heat sink 10, heat sink 10 is arranged on the lower end of television rear cover forming cavity 5.
Antiadhesion barrier 6 is arranged on lower end and the upper end of die shoe 2 of upper bolster 1.
The diameter of limit injected hole 7 and middle injected hole 8 is more than the diameter of sprue channel 9.
Middle injected hole 8 is provided with 3.
Limit injected hole 7 is provided with 6, and is evenly distributed on upper bolster 1.
During use, upper bolster 1 is linked together with draw-in groove 4 by fixture block 3 with die shoe 2, then molding materials is injected to television rear cover forming cavity 5 by middle injected hole 8 and limit injected hole 7, after material feeding completes, by the thermolysis of heat sink 10, material is cooled down, television rear cover i.e. molding, and it is proposed that upper bolster 1, bonnet is carried out demoulding process.
Although the technical solution of the utility model having been done the most detailed elaboration and having enumerated; it is to be understood that; to those skilled in the art; above-described embodiment is made amendment or uses the replacement scheme of equivalent; this is apparent to those skilled in the art; these modifications or improvements on the basis of without departing from this utility model spirit, belong to the scope that this utility model is claimed.
