Detailed description of the invention
For further understanding content of the present utility model, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
In conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the one of the present embodiment vacuumizes mould, comprise patrix 1, counterdie 6, sealed sliding framework 3, resilient support assemblies, planar seal ring 2, side seal circle 7 and vacuumize suction inlet 9, on described counterdie 6, offer the die cavity for placing product 8, the periphery of described sealed sliding framework 3 in die cavity is also trapped among the region of die cavity the inside of sealed sliding framework 3, sealing sliding sash frame 3 is connected with counterdie 6 by resilient support assemblies, and described resilient support assemblies is used for supporting sealed sliding framework 3 and moves up and down.Resilient support assemblies in the present embodiment comprises guide pillar 4 and spring 5, described guide pillar 4 upper ends are connected with sealed sliding framework 3, the lower end of guide pillar 4 is connected with counterdie 6, and described spring 5 is linked in the periphery of guide pillar 4, and this spring 5 is compressed between sealed sliding framework 3 and counterdie 6.The bottom of the sealed sliding framework 3 in the present embodiment is designed with 20 equally distributed resilient support assemblies.
On sealed sliding framework 3 in the present embodiment and the contact-making surface of patrix 1, be provided with planar seal ring 2, on described sealed sliding framework 3 and the contact-making surface of counterdie 6, be provided with side seal circle 7; Described patrix 1 offers and vacuumizes suction inlet 9, and this vacuumizes suction inlet 9 and is connected with die cavity, and vacuumizes suction inlet 9 and be connected with air extractor.In order to ensure certain sealing, sealed sliding framework 3 in the present embodiment is horizontal plane with the contact-making surface of patrix 1, the top of sealing sliding sash frame 3 offers a plane groove, described planar seal ring 2 is placed in this plane groove, the cross section of this plane groove is rectangular configuration, the wide of its cross section is 9.61mm, is 5mm deeply, and the diameter of section of planar seal ring 2 is Φ 8mm.Sealed sliding framework 3 is vertical plane with the contact-making surface of counterdie 6, on the sidewall of this counterdie 6, offer a lateral grooves, described side seal circle 7 is placed in this lateral grooves, the cross section of this lateral grooves is rectangular configuration, and the wide of its cross section is 10.5mm, and height is 6.9mm, the diameter of section of side seal circle 7 is Φ 8mm, in the present embodiment, the contact-making surface gap of the inner side of sealed sliding framework 3 and counterdie 6 is 0.4mm, in good condition while ensureing to do relative motion between the two, and has enough sealings.Wherein, planar seal ring 2, side seal circle 7 are O RunddichtringO, and its material is high-temperature-resisting silicon rubber.
When concrete use, counterdie 6 is arranged on hot plate of vulcanizer, filler under mould open mode (as shown in Figure 2).Counterdie 6 rises to can touch patrix 1 lower surface position time under hydraulic jack effect, and oil cylinder stops rise (as shown in Figure 3).Because the planar seal ring 2 at sealed sliding framework 3 tops is close to the lower surface of patrix 1, and the side seal circle 7 of counterdie 6 sidewalls is close to the inner side of sealed sliding framework 3, makes the surrounding of product die cavity form airtight space.Air extractor outside board is started working, take the air in die cavity away by the suction inlet 9 that vacuumizes on patrix 1, when the pressure in die cavity be-when 1Mpa, counterdie 6 starts to continue to rise under the effect of sulfuration board oil cylinder, sealed sliding framework 3 is forced into the position (as shown in Figure 4) of mould matched moulds.Adhesive tape in die cavity is expressed in die cavity completely, starts afterwards locked mode, pressurizes and vulcanizes.
For big-block engine cover seal, its overall dimensions is all very large and face size is minimum, if adopt common mould pressing process to produce, producing goods has the defects such as starved, stagnant gas, bubble, weld mark on almost apparent.Adopt the mould that vacuumizes of the present embodiment to produce, solve the problem of goods exhaust difficulties in mold process, thoroughly eliminated the defects such as the apparent upper starved of goods, stagnant gas, bubble, weld mark, ensured the quality of goods, the compactness that improves goods, has improved production efficiency.
Below schematically the utility model and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, in the situation that not departing from the utility model creation aim, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
