Abstract
The present invention relates to a PCU air blowing sole and a special forming mould for the sole. The PCU blowing sole mainly comprises the following ingredients of polyvinyl chloride, plasticizing agents, cold endurance agents, stabilizers, foam powder, pigment, etc. The special mould mainly comprises an upper cover and a base, wherein an upper mould, a lower mould, corresponding air inlets/grooves and air outlets/grooves are respectively arranged on the upper cover and the base; the upper mould and the lower mould have a same shape with the sole; a filling block is convexly arranged on the heel part of the upper mould. The soles produced by adopting materials and the special forming mould of the present invention have the characteristics of clean and smooth appearance and very high artistic degree; in addition, compared with soles produced by adopting common PVC materials in resistance, wear resistance, etc., the present invention is enhanced notably.
Description
Technical field:
The invention still further relates to a kind of PVC sole forming die of special use.
Background technology:
Sole is one of footwear material common in the shoe-making industry, but adopts the produced sole of present common material to exist many weak points at aspects such as the fineness of intensity, appearance and wearabilities.
See shown in the accompanying drawing 1: the mould of moulding sole generally is divided into two kinds, a kind of is common PVC foaming mould, the air admission hole of this mould and steam vent all are arranged on the counterdie, the chop of benevolence iron bar or strip and block in being evenly distributed with on the patrix, during use, after will being squeezed in the die body through the raw material of high temperature gel by board ejaculation pressure, rely on foaming effect moulding in die body of raw material self.Not good, second-rate by the sole outward appearance that this mould is produced, therefore, generally only be used for producing the low-grade sole of some cheapnesss.The mould of another kind of production foamed shoe sole is a PVC air blowing mould, see shown in the accompanying drawing 1: this mould has a loam cake 01 and a base 02, be respectively equipped with a patrix 011 and a counterdie 021 on loam cake 01 and base 02 corresponding surface, air admission hole 012 and steam vent 022 are separately positioned on patrix 011 and the counterdie 021, in addition, convex with some interior benevolence iron bars 013 on its patrix 011; During use, before ejaculator is clamp-oned raw material in the die body, by blowning installation air admission hole 012 is blown, behind gassy in the die body, promptly begin charging, gas in the die body is discharged by steam vent 022 under the effect of raw material entry pressure, raw material in clamp-oning die body in, slightly foaming in die body, then final molding is complete sole in die body, but because raw material when in the die body of this mould, flowing, the some iron bars 013 that are provided with on its patrix 011 can play the effect of flow-disturbing, raw material is being divided into several strands through behind the iron bar 013, these several strands of liquid materials are joined and are stopped to flow in the heel region of die body, make that tangible joint line appears in its heel region of sole after the final molding, and fineness is relatively poor, influenced the aesthetic property of product, its quality also still remains further to be improved.
Summary of the invention:
The object of the present invention is to provide a kind of PVC sole forming die.
For achieving the above object, PVC sole forming die of the present invention comprises upper die and lower die, is laid with corresponding air admission hole/groove and steam vent/groove at the periphery of upper die and lower die, in addition, also be provided with charging hole on the patrix, the rear heel of described patrix convexes with a filling block.
As improvement of the technical scheme, the preceding metacarpus of described patrix also convexes with filling block, is provided with iron bar between two filling blocks, in order to flow and the minimizing bag empty phenomenon of control raw material in die body, increases its support force.
As improvement of the technical scheme, described charging hole is a nozzle, can carry out side penetrate, keep off penetrate, direct projection, oblique fire etc.
As improvement of the technical scheme, described upper die and lower die periphery is respectively arranged with sealing strip, is used to seal gas in the die body.
As improvement of the technical scheme, on base, also be provided with the air bleeding valve that cooperates with steam vent/groove and the mould outside with the adjusting exhaust velocity.
As improvement of the technical scheme, place, counterdie top also offers discharge wind hole.
Adopt the produced sole of the above-mentioned particular manufacturing craft of material fit of the present invention all to be significantly increased at aspects such as the fineness of intensity, appearance and wearabilities, in addition, the heel region of sole can also be eliminated the joint line problem.
Description of drawings:
Accompanying drawing 1 is the structural representation of existing PVC air blowing mould
Accompanying drawing 2 is the structural representation of invention
The specific embodiment:
See shown in the accompanying drawing 2: a kind of PVC sole forming die includes loam cake 10 and base 20, and the rear end of loam cake 10 and base 20 is hinged and is in the same place; Be respectively equipped with shape patrix consistent 11 and counterdie 21 on loam cake 10 and the base 20 with sole, periphery at patrix (11) and counterdie (21) is laid with corresponding air admission hole/groove (111) and steam vent/groove (211), the rear heel of patrix 11 convexes with a filling block 13, if it is thicker to desire the half sole position of moulding sole, for obtaining better molding effect, also can also be convexly equipped with a filling block 14, several short iron bars 15 then can be set between filling block 13 and 14 to play the effect of backgauge at the preceding metacarpus of patrix 10.Because sole reduces between the thickness of preceding metacarpus from rear heel, therefore, filling block 13 and 14 thickness preferably also correspondingly by the back to preceding attenuation gradually, help making the intensity of sole each several part to reach consistent like this.
In order to make raw material can clamp-on die cavity better, the charging hole 12 on the patrix 11 can change nozzle into, and this nozzle can be dissimilar nozzles such as direct projection, side are penetrated, oblique fire.
The sealing strip 112 and 212 that patrix 11 and counterdie 21 peripheries are provided with can be strengthened the sealing of mould, is used to control gas and is slowly discharged by outside exhaust valve positions, improves product quality.
On base 20, also be provided with the steam vent/groove 211 and the mould outside and cooperate to regulate the air bleeding valve 22 of exhaust velocity.
In addition, the processing of can sandblasting of the surface of patrix 11 and counterdie 21 to increase the adhesive force between raw material and patrix 11 and the counterdie 21, also can be offered several wind holes 213 of discharging, so that the mold bottom exhaust is unobstructed on the counterdie 12.
During use, before ejaculator is clamp-oned raw material in the die body, by blowning installation air admission hole/groove 12 is blown, behind gassy in the die body, promptly begin from 12 chargings of nozzle formula charging hole, gas in the die body is discharged (can pass through air bleeding valve 22 with the adjusting exhaust velocity according to clamp-oning in the die body difference of raw material) by steam vent 211 under the effect of raw material entry pressure, raw material in clamp-oning die body after, in die body, flow, when its through the gap between the benevolence 13 in block on the bottom surface of counterdie 20 and the patrix 10 and in flowing through after the benevolence 14, can form the trend of upwards rolling, avoid the problem of the heel region generation joint line of the sole after moulding.When raw material flows in die body, slightly foaming in die body again, finally final molding is complete sole in die body.
