Abstract
The utility model discloses a tension wheel mould which comprises a male mould, a female mould, an upper mould seat and a lower mould seat. The male mould is arranged on the lower mould seat, an edge pressing ring is arranged on the lower mould seat, a locating plate is arranged on the edge pressing ring, the female mould is arranged on the upper mould seat, guide pillars are arranged between the upper mould seat and the female mould in a penetrating mode, the top ends of the guide pillars are cylindrical, a connecting plate and a stripping block are arranged on the upper mould seat, and rubber push pieces are connected between the upper mould seat and the connecting plate. The top ends of the guide pillars of the tension wheel mould are cylindrical, and thus damage to workpieces is avoided. Furthermore, the upper mould seat is connected with the connecting plate through the rubber push pieces, and thus damage to the products when the workpieces are pushed out is avoided.
Description
Technical field
The utility model relates to mould applications, specifically a kind of expansion tightening wheel mould.
Background technology
On existing automobile, need specific mould to produce, when mould carries out converted products, easily occur the situation of bad workpiece of guiding capital, and add man-hour, the strength during due to pressurization is larger, easily makes product stressed excessive.
Existing mould product scrappage is high, and production efficiency is low, causes labour cost, the increase of Master Cost and various expenses, and die cost is double.

(3) beneficial effect
Technique scheme tool has the following advantages: the top of the lead of expansion tightening wheel mould of the present utility model is cylindrical, has avoided damage workpiece.And this upper bolster is connected with connecting plate by rubber push piece, avoided causing the damage to product when releasing workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
In the drawings, 1 die shoe, 2 blank holders, 3 punch, 4 dies, 5 cushion blocks, 6 upper bolsters, 7 rubber push pieces, 8 connecting plates, 9 de-material pieces, 10 limited posts, 11 location-plates.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, for the structural representation of a kind of embodiment of the present utility model, this expansion tightening wheel mould comprises punch 3 and die 4, described punch is arranged on die shoe 1, and described die shoe 1 is provided with blank holder 2 in the both sides that are positioned at punch, and described blank holder is provided with location-plate 11, described die is arranged on upper bolster 6, between described upper bolster 6 and die, be penetrated with lead, preferably, interference fit between upper bolster and lead.The top of described lead is cylindrical, and the end of described lead contacts with workpiece, and described blank holder 2 is provided with location-plate 11.Between described upper bolster and die, be provided with cushion block 5, described upper bolster 6 is provided with connecting plate 8, de-material piece 9 and limited post 10, described upper bolster 6 is connected with connecting plate 8 by rubber push piece 7, between upper bolster and connecting plate 8, be also provided with limited post 10, described connecting plate 8 is being provided with de-material piece 9 towards a side of punch.
The top of the lead of expansion tightening wheel mould of the present utility model is cylindrical, has avoided damage workpiece.And this upper bolster is connected with connecting plate by rubber push piece, avoided causing the damage to product when releasing workpiece.Preferably, be also provided with slide block between described punch and die, this slide block can be arranged on the surface of location-plate, is connected with an adjusting rod on described slide block.The utility model can be adjusted the formation that forms product by this slide block, can reach a mould multiple product structure.And, by the position of adjusting rod adjusting slider, be convenient to adjust.
The surface of die of the present utility model is provided with ripple glaze, effectively reduces the mould of product cost, can directly manufacture waveform product, has reduced the problem of secondary operations.Preferably, the surface of described location-plate 11 is provided with plastic sheeting, has prevented that workpiece from adding damage in man-hour.
In die of the present utility model, be provided with exhaust block, add high-efficient vacuumizing exhaust block in this mould, according to mold flow analysis, redesign cast gate, change runner, make product yield improve 20%, qualification rate reaches 98%.Preferably, in the cavity of described die, be also provided with runner.Preferably, be also provided with die shank on described upper bolster, described die shank is connected with the output of forcing press.
Adding man-hour, blank positions with the location-plate on blank holder, starts forcing press, and die is descending, and contact blank stretches, and limited post contacts with upper bolster, forms product.If workpiece, at die, is released by rubber push piece, if stay punch, by blank holder, ejected.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
