Abstract
The utility model discloses a kind of polyurethane bending restrictor to exempt from turning mould, including mould crust and die cover, it is characterized in that, the mould crust is provided with formed product chamber, the die cover is covered above forming cavity, and die cover is sealedly and fixedly connected with mould crust, smooth at the top of the die cover, be provided with the exhaust outlet for entering geat and at least one protrusion of a protrusion at the top of the die cover, it is described enter geat and the exhaust outlet communicated with forming cavity.The utility model exhaust outlet rational in infrastructure that enter geat and at least one protrusion by being provided with a protrusion at the top of die cover, when making casting mold, in the exhaust outlet that bubble is discharged to.Avoid because opening cast product needs to cut off great quantities of spare part, and caused waste of raw materials problem, turnery processing process is cut, shortens the time, improves operating efficiency.
Description
Technical field
The utility model belongs to limiter die casting field, more particularly to a kind of polyurethane bending restrictor exempts from turning mould
Tool.
Background technology
With attention degree increase of the people to extra large cable, and the bending restrictor of extra large cable is protected also and then to increase, in the market is more
Number is using polyurethane bending restrictor protection extra large cable.Polyurethane bending restrictor is in process of production using die casting side
Method manufacture, as shown in figure 1,100 be uncovered structure, 200 be mould.Because needing to be vented bubble, it is necessary to by mould in former casting process
Tool is designed as open topped structure 100, and uncovered structure 100 is into geat, is exhaust outlet again.Cast when, gate spool from
Stretched at open topped structure 100, raw material be poured into the position of uncovered structure 100, and at uncovered structure 100 portion leave it is more
Surplus, bubble is allowed to drain into non-product position；After solidification, unnecessary bubbles part is removed by turnery processing, this mould 200 is set
Meter can cause a large amount of wastes of raw material, increase Industrial Solid Waste, but also can increase machining process, lose time, cause
Cost increase.
Utility model content
Technical problem to be solved in the utility model is：A kind of polyurethane bending restrictor is provided and exempts from turning mould, is used
To solve existing mold in opening cast because being vented bubble, it is necessary to which lathe process removal redundance, causes lot of materials to waste, increase
Sequence is processed, the problems such as losing time, and improve cost.
In order to reach above-mentioned technique effect, the technical solution adopted in the utility model is：A kind of polyurethane bending restrictor
Exempt from turning mould, including mould crust and die cover, the mould crust is provided with formed product chamber, the die cover cover product into
Above die cavity, die cover is sealedly and fixedly connected with mould crust, smooth at the top of the die cover, is provided with the top of the die cover
The exhaust outlet for entering geat and at least one protrusion of one protrusion, it is described enter geat and the exhaust outlet communicated with forming cavity.
Further, the mould crust bottom is provided with two solid cylindrical station pin, and pin of standing is connected with formed product chamber.
Further, it is described enter geat it is similar with the shape and structure of the exhaust outlet.
Further, it is described enter geat and the exhaust outlet be hollow ladder shape shaft.
Further, it is described enter geat and it is described protrusion exhaust outlet it is non-conterminous.
Further, the exhaust outlet is two.
Further, it is described enter geat and the exhaust outlet on be equipped with jointing.
Further, the mould crust and die cover are bolted.
Compared with prior art, the beneficial effects of the utility model are：The utility model is rational in infrastructure by die cover
Top is provided with the exhaust outlet for entering geat and at least one protrusion of a protrusion, when making casting mold, exhaust outlet that bubble is discharged to
It is interior.Avoid because opening cast product needs to cut off great quantities of spare part, and caused waste of raw materials problem, cut turnery processing
Process, shorten the time, improve operating efficiency.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, described in detail.
Brief description of the drawings
Fig. 1 is original mould planform.
Fig. 2 is the utility model die structure dwg.
Fig. 3 is the utility model mould top view.
Each label and corresponding entitled in figure：1. mould crust, 2. die covers, 3. enter geat, 4. exhaust outlets.
Embodiment
As shown in Figure 2 and Figure 3, a kind of polyurethane bending restrictor exempts from turning mould, including mould crust 1 and die cover 2, institute
State mould crust 1 and be provided with formed product chamber, the die cover is covered above formed product chamber, and die cover 2 and the sealing of mould crust 1 are solid
Fixed connection, the top of die cover 2 is smooth, and what the top of die cover 2 was provided with protrusion enters geat 3 and at least one
The exhaust outlet 4 of protrusion, it is described enter geat 3 and the exhaust outlet 4 communicated with forming cavity.In casting process, raw material are from entering
Geat 3 pours into formed product intracavitary in mould, and bubble is discharged in exhaust outlet 4, stops pouring into, and progress turning is not required to after solidification and is added
Work, redundance is removed, and do not influence product appearance, save material, improve efficiency.
The present invention is not limited to above-mentioned specific embodiment, for the person of ordinary skill of the art from above-mentioned structure
Think of sets out, and without performing creative labour, made a variety of conversion, is within the scope of the present invention.
