Abstract
The invention discloses a die-casting punch. The die-casting punch comprises a punch core, wherein an abrasion-resistant work layer is arranged at the outer end of the punch core in a sleeved mode, a revolving thread is arranged on the surface of the punch core, and a revolving passage is formed between the punch core and the abrasion-resistant work layer through the revolving thread. The die-casting punch effectively lowers the temperature in the die-casting process and reduces expansion friction by using circulation of water in the punch core. Meanwhile, the abrasion-resistant work layer is arranged at the outer end of the punch core, the service life of the punch is prolonged, the frequency of replacing the die-casting punch is reduced, the die-casting work efficiency is greatly improved, and the die-casting cost is also reduced.
Description
Technical field
The present invention relates to field of die casting machines, particularly a kind of diecasting punching head.
Background technology
The diecasting punching head that existing die casting machine uses is all used all-in-one-piece magnesium iron or cast iron drift, its price is low, but its wearability, thermal conductivity and cooling effect are poor, when work, thermal expansion is large, and the wearing and tearing between the charging basket that the diecasting punching head on die casting machine coordinates are also large, therefore the life-span of diecasting punching head very short, only have left and right its service life 800 times, therefore need to change frequently diecasting punching head.Can reduce greatly operating efficiency owing to changing drift like this, need long downtime because change a diecasting punching head.Ye You producer utilizes that beryllium-bronze tool has good wearability, thermal conductivity and toughness, uses beryllium-bronze diecasting punching head, can reach its service life up to ten thousand times, but expensive because of it, most producers would rather be used common drift.
Summary of the invention
It is longer that the technical problem that the present invention mainly solves is to provide a kind of service life, can effectively reduce the friction of expanding, the diecasting punching head that cooling down is effective.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of diecasting punching head is provided, comprise drift core, described drift core outer end is arranged with wear-resisting working lining, on described drift wicking surface, be provided with revolution screw thread, between drift core and wear-resisting working lining, form chicane by revolution screw thread.
In a preferred embodiment of the present invention, described drift core is common spheroidal graphite cast-iron.
In a preferred embodiment of the present invention, described wear-resisting working lining is beryllium-bronze.
In a preferred embodiment of the present invention, described wear-resisting working lining thickness is 3-6cm.
In a preferred embodiment of the present invention, on described drift core, be provided with backwater hole, the bottom of drift core has delivery port.
The invention has the beneficial effects as follows: diecasting punching head of the present invention has utilized the circulation of water in drift core, temperature while effectively having reduced die casting, reduce the friction of expanding, in drift core outer end, wear-resisting working lining is set simultaneously, extend the service life of drift, reduce the frequency of changing diecasting punching head, greatly improved the operating efficiency of die casting, also reduced the cost of die casting simultaneously.
Brief description of the drawings
Fig. 1 is the perspective view of diecasting punching head one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, drift core, 2, wear-resisting working lining, 3, convolution screw thread, 4, chicane, 5, backwater hole, 6, delivery port, 7, water inlet.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of diecasting punching head, comprises drift core 1, and described drift core 1 outer end is arranged with wear-resisting working lining 2, is provided with revolution screw thread 3 on described drift core 1 surface, between drift core 1 and wear-resisting working lining 2, forms chicane 4 by revolution screw thread 3.
Described drift core 1 is common spheroidal graphite cast-iron, and described wear-resisting working lining 2 is beryllium-bronze, and wear-resisting working lining 2 thickness are 3-6cm, and this architectural feature is bimetallic, no matter with which kind of technique edge be nested together and all can.
On described drift core 1, be provided with backwater hole 5, the bottom of drift core 1 has delivery port 6.
In the time starting die casting program, cooling water enters drift core 1 by the water inlet 7 of the drift core 1 of hollow, then by the delivery port 6 of drift core 1 lower end, cooling water is delivered to drift foremost.Owing to being provided with convolution screw thread 3 on drift core 1 surface, therefore cooling water can be realized the convolution in drift core 1 periphery, and then backwater hole 5 backflows of entering on drift core 1 enter in drift core 1, circulation successively, the temperature that can keep so all the time arriving drift top is lower, has improved cooling effectiveness.
Diecasting punching head of the present invention has utilized the circulation of water in drift core 1, temperature while effectively having reduced die casting, reduce the friction of expanding, in drift core 1 outer end, wear-resisting working lining 2 is set simultaneously, extend the service life of drift, reduce the frequency of changing diecasting punching head, greatly improved the operating efficiency of die casting, also reduced the cost of die casting simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
