Abstract
The utility model provides a T-shaped bolt closed die which is formed in one time and enables the cost to be reduced and belongs to the technical field of die forming devices. The T-shaped bolt closed die comprises an upper die and a lower die, wherein the lower end of the upper die is protruded, the middle of the protruded portion is provided with an upper die cavity, the middle of the lower die is provided with a lower die cavity matched with the protruded portion of the upper die, and when the die is closed, the protruded portion of the upper die is located in the lower die cavity of a lower die plate, and the upper die cavity is identical to the upper half portion of the top of a bolt in size. The T-shaped bolt closed die is mainly applied to the die forming aspect.
Description
Technical field
The T-shaped bolt closed molds of the utility model, belongs to mould molding device technical field.
Background technology
As shown in Figure 1, the lower end mid portion of the mold of traditional T-shaped bolt has impression, impression size is bolt top size, there are burr on both sides, bolt top after forging, must carry out trimming, just can make the bolt of moulding, increase equipment operation, increase cost, be therefore necessary to be improved.
Utility model content
The deficiency existing in order to overcome prior art, the T-shaped bolt closed molds of one that provide a kind of one-shot forming, reduces costs.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
T-shaped bolt closed molds, comprises upper die and lower die, and patrix lower end is outstanding, and has upper impression in the middle of ledge, has the lower impression agreeing with the phase-splitting of patrix protuberance in the middle of counterdie, and when closed, the ledge of patrix is positioned at the lower impression of lower bolster.
The size of described upper impression is bolt top the first half size.
The beneficial effect that the utility model compared with prior art had is:
The utility model one-shot forming, a mould can forge four bolts simultaneously, has reduced equipment operation, has reduced cost.
Brief description of the drawings
Below by accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the mould of the T-shaped bolt of former making;
Fig. 2 is the mould that the utility model is made T-shaped bolt;
