Abstract
A kind of mould with lifting bolt of the utility model, comprises the suspension ring screw be arranged on mould, and the cross section of described suspension ring screw die cavity is T-shaped shape.Through 0.4-1mm larger than thread Pilot hole internal diameter in the bottom of thread Pilot hole, suspension ring screw is T-shaped, the inner radial dimension of suspension ring screw is compared existing suspension ring screw and is become large, the front end of lifting bolt can not be blocked, ensure that lifting bolt can all be screwed into suspension ring screw, lifting bolt outer end end face and suspension ring screw external port end face can fit tightly, according to mechanics principle, the suspension ring screw that the method obtains coordinates lifting bolt, that greatly can improve lifting bolt is subject to force intensity, in lifting process, security is also higher.The non-lifting bolt made according to GB on the market, the advantages such as length is slightly long, but also can match with suspension ring screw of the present utility model, and therefore adaptability is wider.The utility model belongs to technical field of mold.
Description
Technical field
The utility model relates to technical field of mold, especially relates to a kind of mould with lifting bolt.
Background technology
In recent years, along with the develop rapidly of plastics industry and general in engineering plastics improving constantly in intensity and precision etc., the range of application of plastic products is also in continuous expansion, as: household electrical appliance, instrument and meter, construction equipment, the various fields such as auto industry, haberdashery and hardware, the ratio shared by plastic products just rapidly increases.A working of plastics reasonable in design often can replace multiple conventional metals part.The trend of industrial products and daily product plastic constantly rises.And the production of these plastic products be unable to do without mould, mould is a kind of instrument producing plastic products, and it is made up of some basic plates such as moving platen, solid plate and parts.
Conveniently carrying mould, carries out lifting carrying at framed side opening lifting bolt and supporting suspension ring screw.In recent years, the awareness of safety of people is more and more stronger, thus to the crudy of suspension ring screw and requirement on machining accuracy more and more higher.And traditional processing method, the needs of client cannot be met gradually.
Suspension ring screw on traditional mould as shown in Figure 1, interior end section be one leg-of-mutton.Processing method based on current die industry suspension ring screw limited, and adopts radial drilling machine, first gets thread Pilot hole with fluted drill, then carry out tapping (i.e. machining internal thread) with screw tap; The drawback of this processing method is: radial drill main shaft power is large not; precision is not high enough; in process, spindle swing is severe; beat serious, the perpendicularity of thread Pilot hole cannot be ensured, the thread Pilot hole made often easily occurs tilting, oval, coarse; thread Pilot hole diameter tolerance is wayward; add that fluted drill there will be wearing and tearing in process, often the cylindrical hole of thread Pilot hole can be made conical bore, namely the outer diameter of thread Pilot hole is larger than inner diameter.Cause after tapping, the suspension ring screw on existing mould exists not enough: lifting bolt can not be completely contrary bottom tooth hole, and cause the end face of the end face of lifting bolt tail end and suspension ring screw external port to fit closely, workpiece rework rate is high; In addition, in lifting process, only have the screw portion of suspension ring stressed, from lever principle, suspension ring screw portion is stressed comparatively large, is easy to like this cause suspension ring to be pulled off, there is potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of mould with lifting bolt, can ensure that screw can be screwed to bottom tooth hole, improves lifting bolt and is playing the security in process; Simultaneously also reduce rework rate, produce faster, quality is more stable; Thus enhance the market competitiveness, reduce the gap with international molding level, promote Chinese Die Industry class, strengthen the competitive level of domestic mould.
Technical solution adopted in the utility model is: a kind of mould with lifting bolt, comprises the suspension ring screw be arranged on mould, and the cross section of described suspension ring screw die cavity is T-shaped shape.
The outside aperture 0.4-1mm less of the inner aperture of suspension ring screw of suspension ring screw.
The degree of depth of described suspension ring screw the inner is 2-3 tooth distance.
Described suspension ring screw port chamfering is 45 degree.
The beneficial effects of the utility model are: a kind of mould with lifting bolt of the utility model, through 0.4-1mm larger than thread Pilot hole internal diameter in the bottom of thread Pilot hole, suspension ring screw is T-shaped, compared with the taper shape bottom original suspension ring screw, the inner radial dimension of suspension ring screw of the present utility model becomes large, tool following points advantage;
1, the inner radial dimension of suspension ring screw compares the change of existing suspension ring screw greatly, the front end of lifting bolt can not be blocked, ensure that lifting bolt can all be screwed into suspension ring screw, lifting bolt outer end end face and suspension ring screw external port end face can fit tightly, according to mechanics principle, the suspension ring screw that the method obtains coordinates lifting bolt, and that greatly can improve lifting bolt is subject to force intensity, in lifting process, security is also higher.
2, on the market non-according to GB make lifting bolt, length is slightly long, but also can match with suspension ring screw of the present utility model, and therefore adaptability is wider.

Detailed description of the invention
With reference to shown in Fig. 1, Fig. 2, a kind of mould with lifting bolt of the utility model, comprises the suspension ring screw 2 be arranged on mould 1, and the cross section of described suspension ring screw 2 die cavity 2.1 is T-shaped shape.
The outside aperture d1 0.4-1mm less of suspension ring screw 2 inner aperture d2 of described suspension ring screw 2.Described outside aperture d1 is threaded this section, and described aperture, inside d2 refers to for holding this part of lifting bolt leading portion.
The degree of depth h of described suspension ring screw 2 the inner is 2-3 tooth distance.
Described suspension ring screw 2 port chamfering is 45 degree.
1, the inner radial dimension of suspension ring screw compares the change of existing suspension ring screw greatly, the front end of lifting bolt can not be blocked, ensure that lifting bolt can all be screwed into suspension ring screw, lifting bolt outer end end face and suspension ring screw external port end face can fit tightly, according to mechanics principle, the suspension ring screw that the method obtains coordinates lifting bolt, and that greatly can improve lifting bolt is subject to force intensity, in lifting process, security is also higher.
2, on the market non-according to GB make lifting bolt, length is slightly long, but also can match with suspension ring screw of the present utility model, and therefore adaptability is wider.
3, the utility model belongs to domestic initiation, solve various typical standard lifting bolt cannot completely contrary enter a great problem of suspension ring screw.
