Abstract
The invention discloses a shoe outsole production technology. The shoe outsole production technology includes the manufacturing steps of a, fusing a main rubber material or polyurethane; b, preparing cotton cords which can be preplaced on a lower mould body or hung on an upper mould body in advance; c, injecting the fused main material with a vulcanizing agent, a foaming agent and a blowing promoter in a mould; d, combining the upper mould body with the lower mould body, heating and vulcanizing to shape. By the technical scheme, the shoe outsole has the advantages that by means of adding a cotton cord placing step, gas guiding performance of the cotton cords is utilized, gas generated during foaming shaping can be vented timely and uniformly, uniformity of foaming and shaping is guaranteed, a shoe outsole with tiny small foaming holes can be obtained, and abrasive resistance, tear resistance and attractive appearance of the shoe outsole can be improved greatly.
Description
Technical field:
The present invention relates to the production technology at a kind of footwear large end.
Background technology:
As everyone knows, the footwear large end is one of footwear component affecting mankind's Vola ambulation comfortableness, footwear large end flexibility is poor, Heavy Weight all can have a strong impact on the comfortableness of shoes dress, and the footwear large end density that traditional manufacture craft is produced is large, wearability, ageing-resistant, the poor-performings such as corrosion-resistant and tear-proof, in order to solve the problem, have developed in industry and adopt foam process to produce the footwear large end, but the foaming shoe of the prior art large end, is subject to the impact of mould structure and foam process self problem, a large amount of gas is produced in mould during foaming, if do not discharge, foaming shoe large end finished product is overall from the inside to the outside all with the abscess that a large amount of volume is larger, the existence of large abscess can have a strong impact on the good looking appearance degree at the footwear large end, and wearability, tear resistance is all poor.
In order to Exhaust Gas, have producer to be provided with air discharge duct in the junction of mould, but this air discharge duct can only discharge the gas near air discharge duct, can not discharge in time away from the gas in the position of air discharge duct, and air discharge duct is also easily blocked, affect the normal discharge of gas.
So no matter be traditional foam production technique or set up the production technology of air discharge duct in a mold, during foaming, the exhaust at the footwear large end is all uneven all the time, foaming in mould is very uneven, have a strong impact on the quality at the footwear large end, expect the high-quality foaming shoe large end, key is how when foam production, the gas produced when can discharge foaming in mould fast, equably.
Summary of the invention:
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, providing one can discharge foamed gas in time, equably, produce the very tiny footwear of abscess foam production technique of the large end.
Object of the present invention can be realized by following technical scheme: the production technology at a kind of footwear large end, and its manufacturing process is as follows: the main material rubber of a. melting or polyurethane; B. get out cotton cord, cotton cord can be placed in counterdie in advance, also first can be hung on patrix; C. the main material after melting is injected in mould together with vulcanizing agent, blowing agent, blowing promotor; D. matched moulds baking is shaping.
After adopting the technical program, compared with prior art, the technical program has the following advantages: by increasing the operation of placing cotton cord together in traditional foam process, utilize the air guide performance of cotton cord, the gas produced when can discharge foaming in time, equably, thus the uniformity ensureing foaming, obtain the very tiny footwear of the abscess large end, both can improve wearability, the tear resistance at the footwear large end, greatly improve good looking appearance degree again.
Accompanying drawing illustrates:
Fig. 1 is the structure chart of footwear of the present invention large end production technology embodiment one when patrix places cotton cord;
Fig. 2 is the structure chart of footwear of the present invention large end production technology embodiment two when counterdie places cotton cord.
Detailed description of the invention:
Below in conjunction with accompanying drawing, this technology is described further.
Embodiment one: the production technology at the footwear large end, its manufacturing process is as follows: the main material rubber of a. melting or polyurethane; B. get out cotton cord 1, cotton cord 1 is hung on the position between the positive post 3 of patrix 2 in advance, and as shown in Figure 1, the length of cotton cord 1 will can expose to the external world with its two ends and be as the criterion after matched moulds, ensures normally carrying out of exhaust with this; C. the main material (i.e. rubber or polyurethane) after melting is injected in counterdie 4 together with vulcanizing agent, blowing agent, blowing promotor; D. matched moulds baking is shaping.
Embodiment two: the production technology at the footwear large end, its manufacturing process is as follows: the main material rubber of a. melting or polyurethane; B. get out cotton cord 1, cotton cord 1 is placed in counterdie 4 in advance, and as shown in Figure 2, the length of cotton cord 1 will can expose to the external world with its two ends and be as the criterion after matched moulds, ensures normally carrying out of exhaust with this; C. the main material (i.e. rubber or polyurethane) after melting is injected in counterdie 4 together with vulcanizing agent, blowing agent, blowing promotor; D. matched moulds baking is shaping.
Here cotton cord is adopted, because cotton cord is very soft, increase tiny cotton cord, it is the merging that can not affect patrix and counterdie, and cotton cord has the characteristic of being good at absorbing fluid and gas, so most suitable absorption and guiding mould inside gas are discharged extraneous, after shaping, it is inner that cotton cord can be hidden in footwear large end finished product, so can not affect outward appearance.Cotton cord absorbs and guides Exhaust Gas and kerosene lamp wick to absorb the kerosene theory of combustion the same.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention.Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore every content not departing from technical solution of the present invention, the equivalence done according to the shape of the present invention, structure and principle change, all should be covered by protection scope of the present invention.
Claims (3)
1. the production technology at the footwear large end, its manufacturing process is as follows: the main material rubber of a. melting or polyurethane; B., before inject main material and other auxiliary material toward counterdie, or after injecting main material and other auxiliary material, air-breathing rope is placed; C. matched moulds baking is shaping.
2. the production technology at a kind of footwear large end according to claim 1, is characterized in that: air-breathing rope is cotton cord.
