Description
Technical field
The utility model relates to a kind of air blowing that is used for formed connected group cotton-padded shoes and cloth shoes and even helps the footwear mould.
Background technology
Tradition manufacturing connects the mould of helping cotton-padded shoes or cloth shoes, generally comprise cope match-plate pattern, center, shoe last and die shoe, center is located between cope match-plate pattern and the die shoe, and cope match-plate pattern, one side of die shoe and center is hinged, the medial surface of cope match-plate pattern and die shoe offers die cavity respectively, be formed with shape in the die cavity of cope match-plate pattern with sole, the corresponding material-holding chamber of pattern, offer the blanking hole and the gas hole that pass to this sole material-holding chamber by the lateral surface of cope match-plate pattern on the cope match-plate pattern, the dismountable mode of shoe last is flush-mounted in the die cavity of die shoe, and protrude outside the die cavity of die shoe the bottom of shoe last, but center comprises the left center and the right center of opening and closing left and right, the two relative side of left side center and right center is concaved with recess respectively, and be formed with the installing hole that closely embeds for the shoe last bottom between two recesses, and be formed with the corresponding material-holding chamber of shape with the two sides of vamp between the madial wall of this installing hole and shoe last bottom, and offer lateral surface by die shoe on the die shoe and pass to exhaust passage in this material-holding chamber.
This company helps the manufacture process of footwear mould to be, earlier face cloth vamp and shoe-pad one are made moulding, again with the insole covers of moulding on shoe last, by the blowning installation in the external world gas hole is blown then, behind gassy in the material-holding chamber of footwear mould, promptly begin the blanking hole of material from cope match-plate pattern flowed in the material-holding chamber, gas in the material-holding chamber is discharged by steam vent under the effect of material entry pressure, material in clamp-oning material-holding chamber in, material slightly foaming in material-holding chamber again, foaming sole on the bottom surface of final molded shoe pad in the footwear mould, thus complete cotton-padded shoes or cloth shoes formed.It is PVC foaming footwear moulds that but this company helps the footwear mould, and it is applicable to PVC high foaming material material, and the density of PVC high foaming material material is relatively poor, makes the toughness of moulding sole relatively poor, thereby causes sole to rupture easily.In order to overcome the problems referred to above, new material for sole of shoe-PVC air blowing material has appearred on the market, and its density is higher, makes the toughness of moulding sole better.But PVC air blowing material needs just can carry out blow molding under confined space, and existing P VC foaming even helps the footwear mould to be provided with the exhaust passage, and the matched moulds place of each template does not all have sealing device in the footwear mould, existing P VC foaming is connected help the footwear mould not to be suitable for the blow molding of PVC air blowing material.
In view of this, the inventor connects the structure further investigation of helping the footwear mould at existing PVC foaming, has this case to produce then.
The utility model content
The purpose of this utility model provides helps the footwear mould a kind of the company with the matching used air blowing of PVC air blowing material.
The technical solution of the utility model is such: a kind of air blowing connects helps the footwear mould, comprise cope match-plate pattern, center, shoe last and die shoe, center is located between cope match-plate pattern and the die shoe, and cope match-plate pattern, one side of die shoe and center is hinged, the medial surface of cope match-plate pattern and die shoe offers die cavity respectively, be formed with shape in the die cavity of cope match-plate pattern with sole, the corresponding material-holding chamber of pattern, offer the blanking hole and the gas hole that pass to this material-holding chamber by the lateral surface of cope match-plate pattern on the cope match-plate pattern, shoe last closely is flush-mounted in the die cavity of die shoe removably, and the bottom of shoe last protrudes from the die cavity of die shoe, but center comprises the left center and the right center of opening and closing left and right, the two relative side of left side center and right center is concaved with recess respectively, and be formed with the installing hole that closely embeds for the shoe last bottom between two recesses, and, be formed with the corresponding material-holding chamber of shape between the madial wall of this installing hole and the bottom of shoe last with the two sides of vamp; Above-mentioned cope match-plate pattern and above-mentioned die shoe are positioned at the outside of above-mentioned die cavity along being respectively equipped with first seal member, and the contact portion between above-mentioned left center and the above-mentioned right center is provided with second seal member.
Above-mentioned first seal member is a sealing ring.
Above-mentioned second seal member is a sealing strip.
After adopting technique scheme, a kind of air blowing of the present utility model connects helps the footwear mould, because cope match-plate pattern and die shoe are positioned at the outside of die cavity along being respectively equipped with first seal member, contact portion between left side center and the right center is provided with second seal member, make between cope match-plate pattern and center like this, between center and die shoe and the sealing between left center and right center better, and do not have in the die shoe exhaust passage is set, then connect in the die cavity of group's footwear mould and can form a closed structure, air blowing of the present utility model is connected help of the blow molding of footwear mould applicable to PVC air blowing material.
