Abstract
The utility model provides an EVA shoe mold with high production efficiency through which two pairs of shoes can be manufactured with one shoe mold. The mold comprises an upper mold, a lower mold, mold cores and a mold extrusion device, one side edge of the upper mold is hinged with the corresponding edge of the lower mold, four independent mold cavities are formed between the upper mold and the lower mold, the four mold cores are respectively and movably arranged in each mold cavity, the mold extrusion device is arranged at the top part of the upper mold, the top parts of all the mold cores are connected with the mold extrusion device after penetrating through the upper mold, and material injection channels and exhaust channels connected with all the mold cavities are arranged on the upper mold or the lower mold. The mold is used for injection moulding of EVA leather shoes.
Description
Technical field
The utility model relates to a kind of EVA leather shoes injection molding, two pairs of EVA footwear of particularly a kind of mould mould.
Background technology
Known leather shoes comprise sole and group's face, produce earlier sole and group's face when producing respectively, by glue or suture both are linked into an integrated entity then, along with updating of EVA injection technique, people have developed EVA leather shoes footwear mould, it is used for disposable sole and group's face to leather shoes and carries out EVA injection moulding, described EVA leather shoes footwear mould comprises counterdie, patrix, core rod and backform device, be provided with the sole of corresponding leather shoes and the die cavity of group's face between the described upper die and lower die, described core rod is removable to be located in the die cavity, the backform device is located at the patrix top, and core rod is connected with the backform device and is used for ejecting the foaming that core rod is finished EVA injection material when die sinking.The weak point of the EVA leather shoes footwear mould of this kind structure is that the space of mould does not have fine utilization, causes production efficiency low.
The utility model content
Two pairs of EVA footwear of mould mould of providing a kind of production efficiency high is provided the purpose of this utility model.
The technical scheme that the utility model adopted is such: two pairs of EVA footwear of a kind of mould mould; comprise upper die and lower die, core rod and backform device; the wherein side of patrix along with the counterdie respective side along hinged setting; be provided with four independently die cavitys between patrix and the counterdie; four removable respectively being located in each die cavity of core rod; described backform device is located at the patrix top; the top of each core rod is passed patrix and is connected with the backform device, and described patrix or counterdie are provided with shoot material passage and the exhaust passage that connects each die cavity.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by four die cavitys are set between patrix and counterdie, four core rods are located at respectively in each die cavity, this footwear mould once shoots material and can finish the EVA injection moulding of two pairs of leather shoes simultaneously like this, footwear mould with respect to one of a known mould, its production efficiency improves four times, and the big spoke degree of heat loss reduces.
Description of drawings
Fig. 1 is an embodiment open mode stereogram;
Fig. 2 is another visual angle open mode stereogram of embodiment;
The specific embodiment
With reference to figure 1 and Fig. 2, embodiment discloses two pairs of EVA leather shoes of a kind of mould footwear mould, comprise patrix 1, counterdie 2, core rod 3 and backform device 4, the rear side of patrix 1 is connected through the hinge along the rear side edge with counterdie 2, be provided with four independently die cavitys 12 between patrix 1 and the counterdie 2, four removable respectively being located in each die cavity 12 of core rod 3, described backform device 4 is located at patrix 1 top, the top of each core rod 3 is passed patrix 1 and is connected with backform device 4, described counterdie 2 is provided with shoot material passage and the exhaust passage that connects each die cavity 12, per two core rods 3 and corresponding die cavity constitute the injection moulding cavity of a pair of leather shoes, this mould once can two pairs of EVA leather shoes of moulding like this, described backform device 4 has two, each backform device 4 is respectively applied for and ejects two core rods 3, described backform device 4 comprises the pressing plate 41 that one links to each other, be located at the position-stopping plate 42 of pressing plate 41 both lateral sides and be located at patrix 1 and pressing plate 41 between spring, when footwear mould matched moulds, two block pressur plates 41 are mentioned the injecting cavity that forms leather shoes to each core rod 3 to patrix 1 top owing to the stop bit effect of position-stopping plate 42, when the die sinking of footwear mould, because position-stopping plate 42 no longer is subjected to the restriction of counterdie, spring band dynamic pressure plate 41 moves down, thereby eject four core rods 3 that are attached thereto, this process is the foamed forming process of EVA footwear mould.Two accompanying drawings of embodiment link to each other the backform device with core rod 3 one be for just son understanding, and in actual the use, described backform device moves with patrix 1.
Claims (1)
1, two pairs of EVA footwear of a kind of mould mould; it is characterized in that: comprise upper die and lower die, core rod and backform device; the wherein side of patrix along with the counterdie respective side along hinged setting; be provided with four independently die cavitys between patrix and the counterdie; four removable respectively being located in each die cavity of core rod; described backform device is located at the patrix top, and the top of each core rod is passed patrix and is connected with the backform device, and described patrix or counterdie are provided with shoot material passage and the exhaust passage that connects each die cavity.
