Abstract
The utility model discloses a dead mould structure of high -efficient anti -sticking, including mold core, thimble and tailstock barrrel, the upper segment of tailstock barrrel is cone structure, the mold core has the through -hole, the upper segment of through -hole with the upper segment of tailstock barrrel corresponds, the tailstock barrrel set up in in the through -hole, the thimble cup joint with sliding in in the tailstock barrrel. The utility model discloses dead mould structure of high -efficient anti -sticking can effectively reduce the wearing and tearing of mold core and thimble, prevents that the thimble card is dead, extension mould life.
Description
Technical field
The utility model is related to a kind of mould structure, more particularly, to a kind of effective abrasion reducing core rod and thimble, prevents
Thimble is stuck, extends the efficiently anti-jamming mould structure of die life.
Background technology
Product, after the completion of die casting, is typically all ejected core rod using thimble by existing die casting, realizes the demoulding.But
It is, due to generally thimble being directly placed in the through hole of core rod in traditional design so that thimble and core rod directly contact, because
This, motion under the high temperature conditions and friction between the thimble of die casting and core rod can produce the problem of a system: 1. core rod
Easily worn and torn by thimble after high temperature works long hours；2. thimble due in thermal expansion in the course of the work easily stuck in mould
In the through hole of core, or even card is caused to break；3. thimble oral area works at high operating temperatures for a long time and is easily cracked, and needs to change core rod,
Mold use short life, production cost is high.
Utility model content
The purpose of this utility model is to provide a kind of effective abrasion reducing core rod and thimble, prevents thimble stuck, prolongs
The efficiently anti-jamming mould structure of long die life.
To achieve these goals, the efficiently anti-jamming mould structure that the utility model provides includes core rod, thimble and top
Needle guard, the epimere of described tailstock barrel is in conical structure, and described core rod has through hole, the epimere of described through hole and described tailstock barrel
Epimere corresponds to, and described tailstock barrel is arranged in described through hole, and described thimble is slidably socketed in described tailstock barrel.
Compared with prior art, because the utility model passes through to arrange a tailstock barrel in the through hole of described core rod, then make
The epimere of described tailstock barrel is in conical structure, and therefore, when described thimble is slidably matched with described tailstock barrel, described thimble can be non-
Often it is easily withdrawn from described tailstock barrel, prevent the stuck consequence ultimately resulting in replacing core rod in described tailstock barrel of described thimble；
Further, since the inwall of described core rod is isolated by described tailstock barrel with described thimble, therefore, described thimble will not be to described mould
Core weares and teares, and need to change described tailstock barrel using rear for a long time, effectively extends the mold use life-span, reduces and produces into
This.
It is preferred that the range of taper of the epimere of described tailstock barrel is 0.5 to 1 degree.
It is preferred that the epimere of described tailstock barrel is 30 to 40 millimeters with the length of the taper fit of epimere of described through hole.
It is preferred that described tailstock barrel is 0.03 to 0.05 millimeter with the gap width of described thimble.By in described thimble
Between set and described thimble, suitably reserved certain gap, such that it is able to compensate thermal expansion, prevents described core rod excessive clamping institute
State thimble, and make described thimble stuck or block disconnected.
It is preferred that the hypomere of described tailstock barrel is straight, the taper of the hypomere of described through hole is 0.5 degree.
Brief description
Fig. 1 is the sectional view of the efficiently anti-jamming mould structure of the utility model.
Specific embodiment
By describing technology contents of the present utility model, structural feature, the effect realized in detail, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
As shown in figure 1, the efficiently anti-jamming mould structure of the utility model includes core rod 1, thimble 2 and tailstock barrel 3, described top
The epimere of needle guard 3 is in conical structure, and described core rod 1 has through hole 11, the epimere of the epimere of described through hole 11 and described tailstock barrel 3
Corresponding, described tailstock barrel 3 is arranged in described through hole 11, the taper a of the epimere of the epimere of described tailstock barrel 3 and described through hole 11
Cooperation scope is 0.5 to 1 degree, length l of the taper fit of epimere of the epimere of described tailstock barrel 3 and described through hole 11 be 30 to
40 millimeters.The hypomere of described tailstock barrel 3 is straight, and the taper b of the hypomere of described through hole 11 is 0.5 degree.Described thimble 2 is slidably
It is socketed in described tailstock barrel 3.
There is between described tailstock barrel 3 and described thimble 2 gap 4, the width in described gap 4 is 0.03 to 0.05 millimeter.
Certain gap 4 is suitably reserved by the inwall in described tailstock barrel 3 and described thimble 2, such that it is able to compensate thermal expansion, prevents
Thimble 2 described in the excessive clamping of described core rod 1, and make described thimble 2 stuck or card is disconnected.
The material that described tailstock barrel 3 is used with described core rod 1 is identical, but the hardness of described tailstock barrel 3 is than described mould
Low 1 to 2 degree of hardness of core 1, such that it is able to make to prevent described thimble 2 from only producing abrasion to described tailstock barrel 3, without described mould
Core 1 weares and teares, and plays the effect protecting described core rod 1.
Compared with prior art, because the utility model passes through to arrange a tailstock barrel 3 in the through hole 11 of described core rod 1,
The epimere making described tailstock barrel 3 again is in conical structure, therefore, when described thimble 2 is slidably matched with described tailstock barrel 3, described
Thimble 2 can easily exit described tailstock barrel 3, prevents described thimble 2 stuck in described tailstock barrel 3, it is to avoid seriously when institute
State thimble 2 to block disconnected and remain in described through hole 11 and need line to cut just can to remove bad thimble 2 or direct change core rod 1
Accident；Further, since the inwall of described core rod 1 is isolated by described tailstock barrel 3 with described thimble 2, therefore, described thimble 2
Described core rod 1 will not be worn and torn；And, described tailstock barrel 3 works under the long condition of high temperature, and oral area is easily cracked, long
Time need to change described tailstock barrel 3 using rear, so can effectively extend the mold use life-span, and shorten up to
60% to 80% repair a die the time, reduces production cost.
Above disclosed only preferred embodiments of the present utility model, can not limit the utility model with this certainly
Interest field, the equivalent variations therefore made according to the utility model claim, still fall within the utility model and covered
Scope.
