Abstract

The invention discloses a T iron forming die. The T iron forming die comprises an upper forming die and a lower forming die, wherein a first mounting hole is concavely formed in the center of the top surface of the lower forming die; a second mounting hole is concavely formed in the bottom surface of the lower forming die; the first mounting hole is connected with the second mounting hole through a connecting hole; the diameter of the first mounting hole, the diameter of the second mounting hole and the diameter of the connecting hole are sequentially reduced; an ejector pin is arranged in the connecting hole and the second mounting hole; a lower die core is arranged in the first mounting hole; a through hole is formed in the center of the lower die core and is connected with the connecting hole and the second mounting hole; the upper end of the ejector pin extends in the through hole; recesses which are symmetrically formed in two sides of the through hole are also formed in the top surface of the lower die core; a third mounting hole is formed in the center of the upper forming die; an upper die core is arranged in the third mounting hole; a projection is convexly arranged in the center of the bottom surface of the upper die core; and the vertical center line of the projection is coincident to the vertical center line of the through hole. By the T iron forming die, raw materials are saved, the machining cost is low, and the production efficiency is high.

Description

A kind of T iron mould
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of T iron mould.
Background technology
Common T iron is all to adopt large wire rod to stamp out product, with large wire rod punching press product out, all wants car post footpath and turning, has seriously dragged slowly the speed of production of whole product, has also increased production cost.
Summary of the invention
The object of this invention is to provide a kind of T iron mould, solved speed of production slowly and the high problem of production cost.
For achieving the above object, the invention provides a kind of T iron mould, comprise the moulding counterdie that is fixedly installed and the shaping upper of up and down setting, the end face central fovea of described moulding counterdie is provided with the first installing hole, the bottom surface of described moulding counterdie is concaved with the second installing hole, described the first installing hole connects described the second installing hole by an intercommunicating pore, the first described installing hole, the diameter of the second installing hole and intercommunicating pore reduces successively, in described intercommunicating pore and the second installing hole, thimble is installed, in described the first installing hole, counterdie core rod is installed, the center of described counterdie core rod is provided with through hole, described through hole is communicated with described intercommunicating pore and the second installing hole, the upper end of described thimble is stretched in described through hole, the end face of described counterdie core rod is also provided with the depression that is symmetrically set in described through hole both sides, the center of described shaping upper is provided with the 3rd installing hole, in described the 3rd installing hole, upper mould core is installed, and the bottom center of described upper mould core convexes with salient point, and the vertical center line of described salient point overlaps with the vertical center line of described through hole.
Preferably, the bottom of described upper mould core protrudes from the bottom surface of described shaping upper, and the end face of described counterdie core rod is concordant with the end face of described moulding counterdie.
Preferably, on described shaping upper, be also provided with locating hole.
Compared with prior art, T iron mould of the present invention can directly carry out punching press to large wire rod and form T iron product, and does not need other lathe processing, not only saved raw material, and processing cost is low, and production efficiency is high.
By following description also by reference to the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used for explaining embodiments of the invention.
Accompanying drawing explanation
Fig. 1 is the cutaway view of T iron mould of the present invention.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1, described T iron mould comprises the moulding counterdie 1 that is fixedly installed and the shaping upper 2 of up and down setting.
The end face central fovea of described moulding counterdie 1 is provided with the first installing hole 11, the bottom surface of described moulding counterdie 1 is concaved with the second installing hole 12, described the first installing hole 11 connects described the second installing hole 12 by an intercommunicating pore 13, the first described installing hole 11, the diameter of the second installing hole 12 and intercommunicating pore 13 reduces successively, in described intercommunicating pore 13 and the second installing hole 12, thimble 3 is installed, in described the first installing hole 11, counterdie core rod 14 is installed, described counterdie core rod 14 center is provided with through hole 141, described through hole 141 is communicated with described intercommunicating pore 13 and the second installing hole 12, the upper end of described thimble 3 is stretched in described through hole 141, the end face of described counterdie core rod 14 is concordant with the end face of described moulding counterdie 1, the end face of described counterdie core rod 14 is also provided with the depression 142 that is symmetrically set in described through hole 141 both sides.
The center of described shaping upper 2 is provided with the 3rd installing hole 21, in described the 3rd installing hole 21, upper mould core 22 is installed, the bottom of described upper mould core 22 protrudes from the bottom surface of described shaping upper 2, and the bottom center of described upper mould core 22 convexes with salient point 221, the vertical center line of described salient point 221 overlaps with the vertical center line of described through hole 141.On described shaping upper 2, be also provided with locating hole 23.
The operation principle of T iron mould of the present invention is: workpiece 4 is placed in the through hole 141 of described counterdie core rod 14, described moulding counterdie 1 maintains static, described shaping upper 2 is in the downward punching press of certain height, until described shaping upper 2 is pressed onto the desired flattening size of drawing workpiece 4, then 2 liters of described shaping uppers return original height, and the thimble 3 in described moulding counterdie 1 ejects described moulding counterdie 1 workpiece 4.
In sum, adopt the T iron mould of said structure directly to large wire rod, to carry out punching press formation T iron product, and do not need other lathe processing, not only saved raw material, and processing cost is low, production efficiency is high.
Invention has been described for above combination most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present invention, equivalent combinations.
