Abstract
The invention discloses a PVC blow molding shoe mold which comprises an upper mold, a lower mold, mold cores and a first cavity, wherein second cavities corresponding to the mold cores are formed in the lower mold, and the number of the second cavities is the same as the number of the mold cores; a limiting rod for limiting the turning angle of the lower mold relative to the mold cores is arranged at a hinge position of the mold cores; a limiting block for limiting the turning angle of the upper mold relative to the mold cores is arranged at the hinge position of the upper mold; when the upper mold and the lower mold are closed, molding cavities are formed between the first cavity and the second cavities in the upper mold and the lower mold, and the number of the molding cavities is the same as the number of the mold cores; the mold cores are arranged in the molding cavities. The PVC blow molding shoe mold is reasonable in structure; by the arrangement of the mold cores, the mold cores are respectively hinged to the upper mold and the lower mold; furthermore, by the arrangement of the limiting rod and the limiting block, the turning positioning of the upper die and the lower die is facilitated, so that a molded product can be conveniently taken out, and one-time molding of a shoe is easily realized.

In prior art, plastics widely use in all trades and professions, PVC air blowing raw material has excellent comprehensive stability effect, high temperature process can be passed through smoothly, cooling and shaping, guarantee to produce the blowing products conformed to quality requirements, its have lighter in weight, soft shockproof outstanding, super skidproof effect, tangent plane are as even in EVA goods, color divergence, the number of advantages such as surface-brightening, lovely luster, wide market, likes by consumer deeply.The known mould for PVC air blowing injection moulding generally comprises upper die and lower die; described upper die and lower die one side is hinged; injection channel and insufflation channel is provided with in patrix or counterdie; this kind of mould at one time in can only the sole of injection moulding PVC air-blow shoe or upper; and can not the sole of disposal molding PVC air-blow shoe and upper, otherwise cannot the demoulding.Simultaneously when with PVC air blowing raw material make toy time also. face similar problem.
Summary of the invention
The object of the invention is to, there is provided a kind of PVC air blowing injection moulding shoe mould reasonable in design, this injection mold structure is reasonable in design, by arranging core rod, this core rod is hinged with upper die and lower die respectively, and be provided with gag lever post and limited block, facilitate the upset location of upper die and lower die, be convenient to the taking-up of injecting products, thus easily achieve the one-shot forming of shoes, need not separate at the bottom of twice difference injection moulded shoes and vamp, improve production efficiency, and reduce production cost.
The technical scheme that the present invention is adopted for achieving the above object is:
A kind of PVC air blowing injection moulding shoe mould, they several core rods comprising a patrix, a counterdie and be arranged between these upper die and lower die, one end of described upper die and lower die is hinged with described core rod respectively, on described patrix, corresponding described core rod is provided with first die cavity identical with described core rod quantity, on described counterdie, corresponding described core rod is provided with second die cavity identical with described core rod quantity, when described patrix and counterdie close up, the first die cavity on these upper die and lower die and the injection moulding die cavity that between the second die cavity, formation is identical with described core rod quantity, described core rod is placed in injection moulding die cavity.
As a further improvement on the present invention, the quantity of described core rod is one.
As a further improvement on the present invention, the quantity of described core rod is two, and these two core rods are set up in parallel and one is connected.
As a further improvement on the present invention, the hinged place of described core rod is provided with the gag lever post of the relative core rod flip angle of the described counterdie of a restriction, and the hinged place of described patrix is provided with the limited block of the relative core rod flip angle of the described patrix of a restriction.
As a further improvement on the present invention, the bottom of described first die cavity is provided with antiskid groove, and the bottom of described second die cavity is provided with decorative groove.
Beneficial effect of the present invention is: the present invention is rational in infrastructure, by arranging core rod, this core rod is hinged with upper die and lower die respectively, and is provided with gag lever post and limited block, facilitate the upset location of upper die and lower die, be convenient to the taking-up of injecting products, thus easily achieve the one-shot forming of shoes, need not separate at the bottom of twice difference injection moulded shoes and vamp, and multiple injection moulding die cavity can be set, the multiple shoes of one-shot forming, improve production efficiency, and reduce production cost.
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
Accompanying drawing explanation
Fig. 1 is structural representation Fig. 1 of the present invention;
Fig. 2 is structural representation Fig. 2 of the present invention;
Fig. 3 is the structural representation of the embodiment of the present invention 1;
Fig. 4 is the structural representation of the embodiment of the present invention 2.
Detailed description of the invention
Embodiment 1: see Fig. 1, Fig. 2 and Fig. 3, a kind of PVC air blowing of the present invention injection moulding shoe mould, it comprises a patrix 1, one counterdie 2 and be arranged at this patrix 1, several core rods 3 between counterdie 2, described patrix 1, one end of counterdie 2 is hinged with described core rod 3 respectively, on described patrix 1, corresponding described core rod 3 is provided with first die cavity 11 identical with described core rod 3 quantity, on described counterdie 2, corresponding described core rod 3 is provided with second die cavity 21 identical with described core rod 3 quantity, described patrix 1 and counterdie 2-in-1 hold together time, this patrix 1, the first die cavity 11 on counterdie 2 and the injection moulding die cavity that between the second die cavity 21, formation is identical with described core rod 3 quantity, described core rod 3 is placed in injection moulding die cavity.The quantity of described core rod 3 is one.The hinged place of described core rod 3 is provided with the gag lever post 31 of relative core rod 3 flip angle of the described counterdie 2 of a restriction, and the hinged place of described patrix 1 is provided with the limited block 12 of relative core rod 3 flip angle of the described patrix 1 of a restriction.The bottom of described first die cavity 11 is provided with antiskid groove 13, the bottom of described second die cavity 21 is provided with decorative groove 22, owing to being provided with antiskid groove 13 and decorative groove 22, product upper surface after injection moulding can be formed the dermatoglyph of emulation, and anti-skidding striped bottom product, can be formed, product is attractive in appearance and use safety is comfortable.
