Detailed description of the invention

Needing exist for explanation, the described noun of locality is left and right, upper and lower is all to define on the basis of the view shown in Fig. 1, it will be appreciated that the use of the described noun of locality should not limit the protection domain that the application is asked.

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of novel automobile bearing dustproof cover mould, it includes upper bracket 1, middle bearing 2, base 3 and punching press post 4, described upper bracket 1, middle bearing 2, base 3 from top to bottom sets gradually, described punching press post 4 vertically arranges in the punching press post holes being sleeved on upper bracket 1 and middle bearing 2, described upper bracket 1 is inlaid with lining 5 around punching press post 4 on the inwall of bottom punching press post holes, multiple gathering sill 4-3 is offered on the sidewall of the punching press post 4 being positioned at the punching press post holes of described middle bearing 2, described middle bearing 2 is connected with on punching press post holes sidewall multiple guiding projection 2-1, the free end of each described guiding projection 2-1 is arranged in a gathering sill 4-3；

The bottom of described punching press post 4 is equipped with upper male mould 6, it is equipped with lower cavity die 7 on described base 3, described upper male mould 6 adapts with lower cavity die 7, multiple upper mold pore is offered in the die face of described upper male mould 6, multiple described upper mold pores collect connection inside upper male mould 6 and are connected with the upper air pump 8-1 being arranged on upper male mould 6 end face, offering multiple lower mold pore in the die face of described lower cavity die 7, multiple described lower mold pores collect connection inside lower cavity die 7 and are connected with the lower air pump 8-2 arranged on the base 3.

During work, stock is placed between upper male mould 6 and lower cavity die 7, punching press capital end is stressed machine control, promote upper male mould 6 that stock is suppressed, lining 5 compression leg 4 that liquidates play fixed supporting role and prevents axial runout, is play fixed supporting role prevented radial rotating by the guiding projection 2-1 being arranged in the gathering sill 4-3 compression leg 4 that liquidates, it is ensured that being normally carried out of punching press, upper male mould 6 is stable with lower cavity die 7 mold closing, and dust cap is difficult to the phenomenon that fold ruptures occur.By arranging upper mold pore in upper male mould 6, lower mold pore is set in lower cavity die 7, it is to avoid when mold closing is extracted, between upper male mould 6 and lower cavity die 7 and stock, forms vacuum, easily occur jump-scrap that dust cap product and mould are caused damage.After in outfit, air pump 8-1 prevents from using for a long time with lower air pump 8-2, upper mold pore blocks with lower mold pore, and inflation is carried out.During use, coordinating punching press post 4 action, when punching press post 4 rises, upper air pump 8-1 and lower air pump 8-2 opens and is inflated.

As shown in Figure 1, on the basis of technique scheme, in described upper bracket 1, the top of punching press post holes is packaged with the first convex shoulder 1-1, it is provided with the second convex shoulder 4-2 on the punching press post 4 of the punching press post holes being positioned at described upper bracket 1, the punching press post 4 between described first convex shoulder 1-1 and the second convex shoulder 4-2 is equipped with spring 10.It is arranged such, 10 cushioning effects of spring, prevents punching press post 4 rising transition, upper air pump 8-1 from colliding with guiding projection 2-1, damage equipment.

As it is shown in figure 1, on the basis of technique scheme, the number of described guiding projection 2-1 is two, the number of described gathering sill 4-3 is two.It is arranged such, meets actually used needs.

On the basis of technique scheme, described lining 5 uses wolfram steel to make.Being arranged such, lining 5 compression leg 4 that liquidates play fixed supporting role, and during work, lining 5 and punching press post 4 occur sliding friction, wolfram steel material can strengthen the wearability of lining 5, increase the service life.

Restriction to this utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art need not to pay various amendments or deformation that creative work can make still within protection domain of the present utility model.
