Abstract
The utility model relates to a compression mold, and particularly relates to a compression mold for valve plastic filler. The compression mold comprises an outer mold sleeve and an inner mold sleeve arranged inside the outer mold sleeve, wherein an inner upper mold and an inner lower mold are arranged between the outer mold sleeve and the inner mold sleeve in a sliding manner, and the inner upper mold is arranged above the inner lower mold. The compression mold has a good molding effect and good filler sealing property and can be used after sinter molding in one step; and secondary pollution caused by leftover materials is avoided.
Description
Technical field
The utility model relates to a kind of compression mould, particularly valve plastic filler compression mould.
Background technology
At present, domestic for the polyflon filler on valve, be all that the section bar rod with polytetrafluoroethylmaterial material processes through instrument lathe, time-consuming taking a lot of work, cost is high, and the polytetrafluoroethylene (PTFE) corner plastics that processing is cut will melt down sintering again, bring secondary pollution, unfavorable environmental protection.
Summary of the invention
The utility model purpose is to provide a kind of good forming effect, and Reliability of Packing Seal is good, and the use field is wide, the valve plastic filler compression mould that scope is wide.
The utility model comprises outer die casing, is arranged on the interior die sleeve in outer die casing, slideable interior patrix and the interior counterdie of arranging between described outer die casing and interior die sleeve, and described interior patrix is arranged on the top of interior counterdie.
Fit tolerance in the utility model between die sleeve, outer die casing, interior counterdie, interior patrix is and is slidably matched, and makes the stressed aftershaping of polyflon mould pressing powder, and the tetrafluoro powder is not excessive, is convenient in demoulding.The utility model good forming effect, Reliability of Packing Seal is good, and once sintered moulding can be used, and non waste edge brings secondary pollution.
The utility model arranges " V " connected in star in the lower end of described interior patrix, arranges in the upper end of described interior counterdie and falls " V " shape boss corresponding to " V " connected in star; The described angle that falls " V " shape boss is less than falling the angle of " V " connected in star, for the ease of filler in compacting.
The angle of " V " connected in star described in the utility model is 100 °, and the described angle of " V " shape boss is 90 °.
The lower end of interior patrix described in the utility model is the plane, arranges " V " shape boss in the upper end of described interior counterdie, and the described angle of " V " shape boss is 90 °, for the ease of suppressing upper filler.
The upper end of interior counterdie described in the utility model is the plane, arranges " V " connected in star in the lower end of described interior patrix, and the described angle of " V " connected in star is 100 °, for the ease of suppressing lower filler.

Fig. 1 is the first structural representation of the present utility model.
Fig. 2 is the second structural representation of the present utility model.
Fig. 3 is the third structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises outer die casing 1, is arranged on the interior die sleeve 2 in outer die casing 1, slideable interior patrix 3 and the interior counterdie 4 of arranging between described outer die casing 1 and interior die sleeve 2, and described interior patrix 3 is arranged on the top of interior counterdie 4; The lower end of described interior patrix 3 arranges " V " connected in star 3-1, arranges in the upper end of described interior counterdie 4 and falls " V " shape boss 4-1 corresponding to " V " connected in star 3-1; The described angle of " V " shape boss 4-1 is 90 °, and the described angle of " V " connected in star 3-1 is 100 °, between described interior patrix 3 and interior counterdie 4, valve packing 5 is set.
As shown in Figure 2, interior patrix 3 ' the lower end be the plane, described interior counterdie 4 ' the upper end arrange " V " shape boss 4-1 ', the described angle that falls " V " shape boss 4-1' is 90 °, described interior patrix 3 ' and interior counterdie 4 ' between arrange valve packing 5 '.
As shown in Figure 3, interior counterdie 4 " upper end be the plane, arrange " V " connected in star 3-1 in the lower end of described interior patrix 3'' ", described " V " connected in star 3-1 that falls " angle be 100 °, between described interior patrix 3 " and interior counterdie 4 ", valve packing 5 is set ".
