Abstract
The utility model discloses a double material injection molded product structure of a sports shoe, which comprises a soft material layer and a hard material layer bonded with the soft material layer, wherein a hard material sealing compound rib site surrounding the soft material layer is arranged on the hard material layer. Due to the adoption of the structure, the poor appearance of the product is greatly improved, the production yield of the product is increased, and the benefit needs of enterprises are met.
Description
Technical field
The utility model relates to the extra quality injection molding product structure of a kind of sport footwear.
Background technology
In the production process of traditional shoe-making industry sole, employing abrasive rubber material is divided in the bottom greatly, middle bottom branch employing plastic cement or EVA (
Ethylene-Vinyl Acetate copolymerEthylene-vinyl acetate copolymer), employing glue bonding is divided in the big end and middle bottom.Because the processing procedure of glue bonding be artificial production, very easily produces the unstable problem that bonds, and the processing procedure of glue involves a large amount of manual works, cause the human cost of product to increase year by year, and a large amount of uses of glue also caused certain pollution to environment.Under such background, adopt wear-resisting TPU to replace rubber, adopt the artificial viscose glue processing procedure of machining processing procedure replacement of extra quality injection moulding to arise at the historic moment.This has not only promoted the bonding stability problem of product, and has reduced the cost of manpower, and the process of the shoe sole production that makes more meets environmental protection requirement.
But, the obscure boundary that the doubler adhesion borderline region that in extra quality injection molding process, is prone to produce produces, or burr bad order, or the bad problem of excessive look.
Be illustrated in fig. 1 shown below; Soft material TPU (Thermoplastic Urethane TPUE) is earlier with injection moulding mode ejection formation; Then the product of this moulding is inserted in the extra quality injection mold as inserts; The injection moulding of the hard material of beginning, the injection moulding through the higher hard material of melting temperature makes the TPU insert surface that certain fusion arranged and bonds together with hard material.
The product structure of Fig. 1 is the primary products structure.Because the fusion effect of hard material can make obscure boundary clear, this structure is overflow look or produce burr in the marginal portion of two kinds of material faying faces.
The product structure of Fig. 2 is the innovative product structure of Fig. 1, and this structure has a step in hard material part, and the faying face of the hard material of soft material is a step surface.The benefit of doing like this is that soft material is the die surface that submerges when putting into mould as inserts, when hard material filling, because the variation of flow direction can not combine boundary to produce overlap, but still possibly have overflow look and the clear problem of obscure boundary.
The utility model content
The utility model purpose is in order to overcome the deficiency of prior art or product; The extra quality injecting products structure of a kind of sport footwear is proposed; Make that the border of two kinds of materials can be very clear in the process of injection moulding; And the issuable burr of borderline region, it is well hidden that the look phenomenon of overflowing obtains, thereby make the outward appearance of product be greatly improved.
Technical scheme: for solving the problems of the technologies described above, the extra quality injecting products structure of a kind of sport footwear that the utility model proposes, the hard bed of material that comprises the soft bed of material and combine with it is provided with the hard material sealing muscle position around the soft bed of material on the described hard bed of material.
Described hard material sealing muscle position is one-body molded with the hard bed of material.
All muscle position and periphery muscle position in described hard material sealing muscle position comprises, and the height of described periphery muscle position be higher than described in the height of all muscle position.
Beneficial effect: compared with prior art; The extra quality injecting products structure of a kind of sport footwear of the proposition of the utility model has the following advantages: through the enforcement of this scheme; The bad order of product is significantly reduced, improve the production yield and the output capacity of product, satisfy the benefit demand of enterprise.
Description of drawings
Fig. 1 is the utility model spherical structure sketch map.
Description of reference numerals:
1. the soft bed of material; 2. the hard bed of material; 3. expect sealing muscle position firmly; 301. interior all muscle position; 302. periphery muscle position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Product structure as shown in Figure 3 comprises the soft bed of material 1 and the hard bed of material 2 that combines with it, on the described hard bed of material 2, is provided with the hard material sealing muscle position 3 around the soft bed of material 1.Like this after soft material is put into mould as inserts; Hard material can be filled hard material sealing muscle position 3 earlier, just begins the filling with soft bed of material faying face then, can be expected firmly that with the excessive look of soft bed of material edge generation and unsharp border sealing muscle position 3 blocks during so hard bed of material filling; The user can't see the imperfect of this part; What see is the hard material sealing muscle position 3 of neat and consistent and combining of TPU, can compare perfection in appearance, and this structure has also been stopped the generation of boundary member burr.
Product structure as shown in Figure 4 is for to do further optimization to the hard material sealing muscle position 3 of structure shown in Fig. 3 on the basis of Fig. 3 product structure; Promptly; All muscle position 301 and periphery muscle position 302 in described hard material sealing muscle position 3 comprises, and the height of described periphery muscle position 302 be higher than described in the height of all muscle position 301.Like this; In the time of can making hard material injection moulding since the pressure of filling the squeezing action that combines the soft material of borderline region is reduced; Simultaneously the issuable slight look that overflows being done apparent sealing handles; Thereby thoroughly solved the excessive look that product structure brought of Fig. 1, burr and the soft material of hard material combine the clear problem of obscure boundary.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
