Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model SMC heat pressing and molding mold;
Fig. 2 is the structural representation of pneumatic jack among Fig. 1;
Fig. 3 is that A among Fig. 1 is to local enlarged diagram.
The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1-Figure 3, the utility model SMC heat pressing and molding mold comprises dynamic model 2 and cover half 1, and dynamic model 2 has the dynamic model die cavity, and cover half 1 has the cover half die cavity.Dynamic model die cavity and cover half die cavity form the die cavity of moulded products 3 behind the matched moulds.Be provided with pneumatic jack 4 in the cover half 1, when mould was opened, pneumatic jack 4 was pushed goods 3 to dynamic model 2, and goods 3 are rested in the dynamic model 2.Pneumatic jack 4 comprises air chamber 401 and push rod 402, and air chamber 401 is arranged in the cover half 1, the sealing of air chamber 401 1 ends, and the other end is communicated with the cover half die cavity.Push rod 402 can move in air chamber 401, and an end of push rod 402 is positioned at air chamber 401, extend out to the cover half die cavity from air chamber 401, the inwall matched in clearance of push rod 402 and air chamber 401.Be provided with air inlet 403 and inlet channel 6 in the cover half 1, air inlet 403 is communicated with air chamber 401 and is used for to air chamber 401 inflations, and inlet channel 6 is communicated with air inlet 403.Also be provided with sealing ring 404 on the push rod 402, sealing ring 404 is enclosed within on the push rod 402, and with the inwall tight fit of push rod 402 and air chamber 401.
During the mould die sinking, ventilate in air inlet 403 by inlet channel 6, gas enters in the confined space of sealing ring 404, push rod 402 and air chamber 401 threes composition by the gap between push rod 402 and air chamber 401 inwalls, after the air pressure in the confined space reaches certain value, can promote push rod 402 and sealing ring 404 moves to goods 3 directions together, end until push rod 402 contacts with goods 3, and push rod 402 is pushed goods 3 to dynamic model 2.When mould was opened fully, goods 3 just rested in the dynamic model 2.Be provided with ejecting mechanism in the dynamic model 2, goods 3 can be ejected dynamic model 2.Because the ejecting mechanism in the dynamic model 2 is a prior art, is not giving unnecessary details at this.The utility model is by being provided with pneumatic jack 4 in cover half 1, after the die sinking of assurance mould, goods 3 are stayed in the dynamic model 2, by the ejecting mechanisms in the dynamic model 2 goods 3 is ejected then to get final product.The percent defective that pneumatic jack 4 has reduced goods 3 is set, has improved production efficiency.
Preferably, pneumatic jack 4 also comprises back-moving spring, and an end of this back-moving spring is fixedlyed connected with push rod 402, and the other end is fixed on the inwall of air chamber 401.When goods 3 broke away from cover half 1 fully, air inlet 403 stopped air inlet, and push rod 402 resets under the effect of back-moving spring.
Preferably, also be provided with guide rod 5 and guide groove in the cover half 1, guide rod 5 can slide in guide groove, and guide rod 5 comprises main part 501 and connecting portion 502, and wherein connecting portion 502 is wedge shape and inserts in the push rod 402, main part 501 and guide groove matched in clearance.When push rod 402 moves downward, drive whole guide rod 5 horizontal movements, because the face that connecting portion 502 contacts with guide rod 5 is the inclined-plane, push rod 402 is moved downward more stably, prevent the too fast damage goods 3 of push rod 402 motions.The axis of the main part 501 in the present embodiment is vertical with the axis of push rod 402, but also can out of plumb, as long as can guarantee that push rod 402 can drive whole guide rod 5 and move.
Preferably, the binding face place of dynamic model die cavity and cover half die cavity is provided with sealing joint strip 7.Dynamic model die cavity and cover half die cavity periphery is fitted during the mould matched moulds, and there is the gap in both at binding face, sealing joint strip 7 is set after, can block the gap, improve sealing effectiveness, reduce the thermal loss in the forming process.Sealing joint strip 7 in the present embodiment is silica gel strips, but is not limited to silica gel strip, and it can also be other resistant to elevated temperatures elastomeric material.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
