Abstract

A novel rubber sole pressing die comprises an upper die plate, a lower die plate, a rotary folding frame, a guide pin and a positioning pin. When the upper template is closed, the eccentric short shaft of the edge of the upper template moves and adjusts in the arc-shaped slotted hole, so that the upper template keeps horizontal position and moves up and down without deflection. The shoe-shaped inner edge of the lower template female die has a cutting edge slightly higher than the plane of the lower template, the outer side of the cutting edge is an arc-shaped groove, the upper template and the lower template have tapered guide pins and positioning pins, and the die can be accurately positioned, so that the defects that the die assembly deviation of the upper template and the lower template of the die is large, the rejection rate is high, raw materials overflow, waste and burrs need to be trimmed and the like are overcome, waste products are not produced during the pressing of the novel die, rubber raw materials are saved, the product quality and the efficiency are improved.

Description

Rubber shoe sole moldering die

The utility model relates to a kind of mould of rubber soles compacting.

Rubber soles compacting tool set in the past has hinge-type and upper and lower mould to separate two kinds of location types, above-mentioned mould, owing to be stressed inhomogeneously, bolster matched moulds deviation is bigger, is easy to generate deflection after stressed, cause percent defective up to more than 5%, rubber raw materials overflows in a large number, about every pair of sole waste elastomeric compound 30 grams, owing to overflowing of raw material, the edge is uneven, every pair of sole all need be cut the limit worker and prune, thereby causes the product cost height, and quality descends.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of cope match-plate pattern gyration folding type mould is provided, and during the revolution matched moulds, cope match-plate pattern moves horizontally, and counterdie inward flange cutting edge is cut edge, bearing pin location, thereby mold alignment.

The utility model is to realize like this, the rubber soles compacting tool set is made up of cope match-plate pattern (punch), lower bolster (die), rotary folding shelf, guide finger and alignment pin, adopts gyration folding type, regulate the cope match-plate pattern horizontal level, bolster is combined as a whole.

Lower bolster has 0.04～0.1 millimeter cutting edge at the inward flange of die footwear shape, and it exceeds 0.03～0.05 millimeter on lower bolster plane, during pressing mold, lower bolster die inward flange cutting edge overflows raw material with die and cuts away shaping, the unhairing limit, the cutting edge outside is a deep-slotted chip breaker, groove is wide 10 millimeters, dark 3 millimeters arc-shaped concave, lower bolster cutting edge inward flange and cope match-plate pattern shoe-shaped punch profile top face fit, its gap is 0.03～0.05 millimeter, the deep-slotted chip breaker in the cutting edge outside, during pressing mold, cutting edge cuts off overflowing on a small quantity of raw material and makes in its deep-slotted chip breaker that is trapped in the outside, and can not enter on the template, and bolster just can close sternly like this.

At the two ends of lower bolster fixedly sleeve-board is housed, one camber line shape slotted eye is respectively arranged on it, the cope match-plate pattern avris is welded with the major axis of the eccentric minor axis of both ends band, eccentric minor axis is set in the camber line shape slotted eye that lower bolster two ends fixed head puts, make bolster be combined into gyration folding type, cope match-plate pattern both can turn round, and adjusted by the position of eccentric minor axis in camber line shape slotted eye again, kept horizontal level to move up and down in the time of can making the cope match-plate pattern matched moulds; Descend along with the reducing of raw material thickness, cope match-plate pattern during pressing mold but and the lower bolster keeping parallelism, can not produce inclination.Rotate the effect of folding stand, because bolster is become one, can not all around move when just being pressing mold work, the matched moulds exactly is avoided damaging of upper and lower mould, after raw material are inserted mould, cope match-plate pattern can slide up and down in company with the variation of raw material thickness, has kept the integral level of mould.

About two alignment pin diameters are housed on the cope match-plate pattern of compacting tool set require to be twice than general mould (25 millimeters of φ), four tapered guide pins are housed also, lower bolster and pin opposite position are the hole, make accurately location of cope match-plate pattern revolution, are not offset.

Because the inward flange of die footwear shape has pointed cutting edge to exceed the lower bolster plane, there is arc groove in the cutting edge outside, and the raw material that overflow during the storage pressing mold close sternly bolster, bolster is combined into one by rotating folding pedestal, can not all around move, during compacting, cope match-plate pattern keeps horizontal level, move up and down, therefore can not produce inclination, the guide effect of bigger alignment pin and tapered guide pin is steadily accurately located matched moulds.Past sole compacting tool set bolster deviation is bigger, be easy to generate deflection after stressed, rubber raw materials overflows and causes a large amount of wastes, the percent defective height adopts mould described in the utility model now, aforesaid advantage, calculate by the producer that produces 5000000 pairs of rubber soled shoes per year, can reduce 250,000 pairs in waste product, be worth about 400,000 yuan, save overflow 150 tons of elastomeric compounds be worth 90 surplus ten thousand yuan.

Concrete structure of the present utility model is further described in conjunction with the accompanying drawings by following examples:

Fig. 1 is lower bolster ［ a 1 ］ shoe-shaped die part front view, 25 millimeters of two dowel holes ［ 2 ］ φ and 25 millimeters (Fig. 5) sliding fits of cope match-plate pattern relevant position alignment pin ［ 10 ］ d=φ are arranged on it, also have four guide pin hole ［ 3 ］ to match with cope match-plate pattern relevant position directing pin ［ 9 ］, Fig. 1 only represents 2 because of cutting a part, upper and lower mould is accurately located, the inward flange cutting edge b ［ 5 ］ of die footwear shape exceeds lower bolster plane c, 0.03 see Fig. 2 for～0.05 millimeter, A-A part section enlarged drawing, the cutting edge outside is deep-slotted chip breaker ［ 4 ］, groove is wide 10 millimeters, dark 3 millimeters arc-shaped concave, when overflowing on a small quantity when cutting off raw material with the storage cutting edge, shoe-shaped inner chamber ［ 6 ］ matched moulds of concave template and cope match-plate pattern shoe-shaped punch fit, the fit clearance of lower bolster cutting edge inward flange and punch footwear profile top face is 0.03～0.05 millimeter.

Fixedly sleeve-board ［ 7 ］ is equipped with at the two ends of seeing Fig. 3 lower bolster, one camber line shape slotted eye is respectively arranged on it, the cope match-plate pattern avris is welded with the major axis ［ 8 ］ of the eccentric minor axis of both ends band, eccentric minor axis is set in the arc-shaped slot that lower bolster two ends fixed head puts, make bolster be combined into gyration folding type, when cope match-plate pattern rotates matched moulds, adjust by the position of eccentric minor axis in camber line shape slotted eye, two ends, cope match-plate pattern keeps horizontal level to move down, with the lower bolster keeping parallelism, can not produce inclination, Fig. 4 is the major axis ［ 8 ］ and face welding position, limit, cope match-plate pattern lower end schematic diagram of the eccentric minor axis of two ends band.Attention: the inner edge boundary line behind the bolster matched moulds will be by the center of major axis great circle, and eccentric minor axis and fixed head put the gap value that camber line shape slotted eye will have 0.5 millimeter, so that adjust the position.

Mould when compacting, treat the mould preheating after, glue stuff compounding is inserted in the counterdie, carry out hot pressing, thereafter mould is opened, take out sole.
