Abstract
The technological process features that raw rubber is molded through high pressure process in mold to produce molded sole, and that the sole is adhered with vamp and circular strip and sulfurized at high temperature and high pressure. The improved technological process of once, rather than twice, sulfurization results in firm adhesion and raised product quality. Furthermore, eliminating edge trimming, polishing adhered reinforcing strip and other steps results in saving in material, labor, equipment and work hours.
Description
The present invention relates to a kind of improved process for producing cloth instep moulded sole rubber shoes.
Rubber mold pressing primer footwear are a kind of of canvas rubber shoe, its production technology generally adopts post-cure technology, the steps include: rubber is put into big bottom die, increase temperature, high pressure makes it moulding, depanning is stubble after deburring, polishing make new advances, again to the big end and upper of a shoe brush coating, bonding and reinforcement bar, outermost glues foxing again, and then carries out post-cure through high temperature, high pressure.Be that grog foxing, group's face glue are raw material because of the big end when adopting the shortcoming of this technology to be post-cure, be easy to generate phenomenon during sulfuration in conjunction with bullet limit, not firm, the big end, influence product quality, the technical staff is seeking ways of addressing this issue always for many years, but does not obtain satisfied result.In addition, once vulcanize the leftover pieces ripe material after the deburring, can not utilize once more, also must be in twice sulfuration through operations such as deburring, polishings, technology is more complicated also.
The purpose of this invention is to provide a kind of new technology that adopts one-step curing production mold pressing primer footwear, to improve production efficiency of products.
The object of the present invention is achieved like this:
A kind of process for producing cloth instep moulded sole rubber shoes, it comprises mixing operation, heat refining operation, removing from mould operation, bonding process, vulcanization process etc., it improves substantially and is: begin from the removing from mould operation, carry out as follows:
A. removing from mould operation, it is the mating plate that raw stock is cut into prescribed level, thickness and weight by the sole specification;
B. mold pressing procedure, it be with the rubber mating plate in mould through pressure forming, become the big end of mold pressing after the depanning;
C. bonding process carries out brush coating with group's face earlier, then will help the big end of face, foxing and mold pressing to carry out bonding;
D. vulcanization process, it is the canvas rubber shoe after bonding to be put into vulcanizing tank carries out high temperature, finished product is finished in the high pressure sulfuration.
The production technology of above-mentioned cloth instep moulded sole rubber shoes, the pressure that adopts in the described mold pressing procedure are 8-11 atmospheric pressure, and temperature is 35 degree-40 degree, finishes together with deburring during depanning.
The production technology of above-mentioned cloth instep moulded sole rubber shoes, adopting temperature in the described vulcanization process is 130 degree-140 degree, pressure is 3-4 atmospheric pressure, time 35-38 minute.
Adopt at the bottom of the mold pressing of the present invention behind the sulfuration process, can make the big end when compression molding without high temperature vulcanized, after the big end moulding still is raw material, during vulcanization process, because the big end and foxing, group's face glue all are rubbers, therefore bonding firm, avoided bullet limit phenomenon of the big end, fundamentally solved long-standing technical barrier.Simultaneously, big end moulding is without sulfuration, and not only tailing can be reused, the big end residual, substandard products are also reusable, saved raw material.The present invention has also reduced operations such as deburring, the sticking reinforcing strip of polishing, has saved manpower, equipment and man-hour, thereby has greatly improved the production efficiency of this footwear.
Fig. 1 is a kind of section of structure of the canvas rubber shoe by explained hereafter of the present invention.
Technical process of the present invention is described in detail as follows: the present invention will carry out following operation: mixing operation, heat refining operation, removing from mould operation, bonding process, vulcanization process.
Earlier with natural rubber, butadiene-styrene rubber, butadiene rubber and various additive (as vulcanizing agent, softening agent, reinforcing agent, pigment etc.) are made transparent green glue stock through mixing operation, become the rubber sheet through the roll compacting of heating of heat refining operation again, and temperature is about 35 degree.The removing from mould operation is cut into mating plate with the rubber sheet according to the requirement of different size sole again, and mating plate is wanted strict and undertaken by certain size, thickness and weight, and semi-finished product were not only full but also do not go out overlap when purpose was compression molding.With the mould extrusion forming that the mating plate behind the removing from mould is put into vulcanizing press, pressure is 4.5 atmospheric pressure, and temperature is 40 degree, finishes together with deburring during the moulding depanning.The big end of mold pressing rubber and upper of a shoe brush coating after the moulding, sticking foxing has saved the deburring in the post-cure technology here, and operations such as adding foxing is glued in polishing, uses the squish machine then, the backing machine, equipment such as Yan Heji make the big end, upper of a shoe, foxing fully bonding.Bonding canvas rubber shoe is put into vulcanizing tank vulcanize, the temperature during sulfuration is controlled to be the 130-140 degree, and pressure is 3-4 atmospheric pressure, and the time is 35-38 minute.
Fig. 1 is the rubber overshoes drawing in side sectional elevation that adopts explained hereafter of the present invention, as we can see from the figure, the polycrystalline substance of this rubber soled shoes is on the big end 1 of mold pressing, there is one deck to hide glue 4, hiding above the glue is foam rubber cushion 5, it middle base fabric 6, in the side of footwear is upper of a shoe 3, foxing 2, the medial surface of foxing 2 is topped on upper of a shoe 3, the outer lower portion of foxing 2 is molded, and to turn over part institute on the edge at the big end 1 topped and be glued together, and this operation is finished the foxing 2 and the big end 1 of mold pressing in process of production behind sulfuration process of HTHP.
Claims (3)
1. process for producing cloth instep moulded sole rubber shoes, it comprises mixing operation, heat refining operation, removing from mould operation, bonding process, vulcanization process etc., it is characterized in that: begin from the removing from mould operation, carry out as follows:
A. removing from mould operation, it is the mating plate that raw stock is cut into prescribed level, thickness and weight by the sole specification;
B. mold pressing procedure, it be with the rubber mating plate in mould through pressure forming, become the big end of mold pressing after the depanning;
C. bonding process carries out brush coating with group's face earlier, then will help the big end of face, foxing and mold pressing to carry out bonding;
D. vulcanization process, it is the canvas rubber shoe after bonding to be put into vulcanizing tank carries out high temperature, finished product is finished in the high pressure sulfuration.
