Description

Master mold anti-sticking structure
[technical field]
The utility model relates to a kind of mould structure, is specifically related to a kind of master mold anti-sticking structure.
[background technology]
Plastic cement products is injection molded by plastic mould, and plastic cement products often can be applied in electronic product, communication product and consumer product etc.In recent years, along with widely using of electronic product, communication product and consumer product, plastic mould also becomes the problem of extensively research.
The projection (BOSS post) of hollow is often had, acting as at the shaping rear built-in nut of plastic cement products of described projection in plastic cement products.If the body of projection is all at the female counterpart of mould, then easily glue master mold.
Refer to shown in Fig. 1, shown in Fig. 1 is the master mold anti-sticking structure of prior art.Master mold anti-sticking structure of the prior art comprises circle and enters son 10, and one end that described circle enters son 10 is fixed in the mother module core 11 in mould, and the other end extend in the projection 13 of product 12.When mould die sinking, caster 14 separates with male template 15, and product 12 enters son 10 with mother module core 11 and circle and departs from and forced stripper mechanism.In order to avoid projection 13 glues mother module core 11, the drafting angle that described circle enters son 10 is very large, and make described projection 13 top have certain angle, this angle is unfavorable for follow-up heeling-in nut.
In view of this, be necessary in fact to develop a kind of new master mold anti-sticking structure, with solve above-mentioned avoid projection to glue master mold while be unfavorable for the problem of follow-up heeling-in nut.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of master mold anti-sticking structure, and this master mold anti-sticking structure is also convenient to follow-up heeling-in nut while avoiding projection to glue master mold.
In order to achieve the above object, master mold anti-sticking structure of the present utility model, it is applied in mould, and described mould comprises bottom plate, upper ejector plate, lower liftout plate, male template, caster, male die core and mother module core, and described master mold anti-sticking structure comprises:
Circle enters son, and its activity is located in described mother module core, and described circle enters the projection of one end conflict product of son;
Sleeve, it has bobbin and fuse, and described bobbin one end is fixed in described upper ejector plate, and the other end is conflicted the projection of described product, and described fuse one end is fixed in described bottom plate, and the other end stretches in described projection.
Optionally, it is T-shaped that described circle enters son, and to enter subactivity located therein for described circle to be correspondingly provided with T-slot in described mother module core.
Optionally, be provided with flexible member in described caster, one end of described flexible member described circle of conflicting enters son.
Optionally, described flexible member is spring.
Compared to prior art, master mold anti-sticking structure of the present utility model, the sub thrust downward to projection is entered by movable circle after mould die sinking, avoid projection and glue mother module core, and the fuse of the sleeve be provided with is stretched in described projection, make projection not need withdrawing pattern, there is not the problem of drafting angle, make projection top there is no angle, facilitate follow-up heeling-in nut.
[accompanying drawing explanation]
Fig. 1 illustrates the schematic diagram of the master mold anti-sticking structure of prior art.
Fig. 2 illustrates master mold anti-sticking structure of the present utility model in the schematic diagram of mould matched moulds state.
Fig. 3 illustrates master mold anti-sticking structure of the present utility model in the schematic diagram of mould die sinking first state.
Fig. 4 illustrates master mold anti-sticking structure of the present utility model in the schematic diagram of mould die sinking second state.
[detailed description of the invention]
Refer to shown in Fig. 2, it depicts master mold anti-sticking structure of the present utility model in the schematic diagram of mould matched moulds state.
A kind of master mold anti-sticking structure, it is applied in mould, described mould comprises bottom plate 100, upper ejector plate 101, lower liftout plate 102, male template 103, caster 104, male die core 105 and mother module core 106, and in the present embodiment, described master mold anti-sticking structure comprises:
Circle enters son 107, and its activity is located in described mother module core 106, conflicts the projection 109 of described product 108 in one end that described circle enters son 107;
Sleeve 110, it has bobbin 111 and fuse 112, and described bobbin 111 one end is fixed in described upper ejector plate 101, and the other end is conflicted the projection 109 of described product 108, described fuse 112 one end is fixed in described bottom plate 100, and the other end stretches in described projection 109.
Wherein, it is 109 T-shaped that described circle enters son, and being correspondingly provided with T-slot 113 in described mother module core 106, to enter son 109 for described circle movable located therein.
Wherein, be provided with flexible member 114 in described caster 104, one end of described flexible member 114 described circle of conflicting enters son 109.
Wherein, described flexible member 114 is spring.
Refer to shown in Fig. 3, it depicts master mold anti-sticking structure of the present utility model in the schematic diagram of mould die sinking first state.After mould die sinking, described caster 104 separates with male template 103, and described flexible member 114 flicks, and circle is entered son 107 downward bullets by the elastic force of flexible member 114, and circle enters son 107 to the downward thrusts of projection 109 1, avoids projection 109 and glues mother module core 106.
Refer to shown in Fig. 4, it depicts master mold anti-sticking structure of the present utility model in the schematic diagram of mould die sinking second state.After the complete die sinking of mould, the ejecting mechanism ejecting product 108 of mould, when ejecting product 108, upper ejector plate 101 and lower liftout plate 102 upwards eject, and be with moving sleeve 110 upwards to eject, the bobbin 111 of sleeve 110 upwards heads on described projection 109, and the fuse 112 of described sleeve 110 detaches from projection 109.
Compared to prior art, master mold anti-sticking structure of the present utility model, son 107 is entered to the downward thrust of projection 109 by movable circle after mould die sinking, avoid projection 109 and glue mother module core 106, and the fuse 112 of the sleeve 110 be provided with is stretched in described projection 109, make projection 109 not need withdrawing pattern, there is not the problem of drafting angle, make projection 109 top there is no angle, facilitate follow-up heeling-in nut.
