Abstract

The utility model relates to an inner surface mould for manufacturing soles being able to changing attached uppers. The utility model has the technical proposal that the mould is provided with a core body and an elasticity movable component arranged on the core body; the core body is divided into separation zones by separation walls; each separation zone is provided with a groove for placing connection components and an embedded magnet block near the periphery position; the middle part of the elasticity movable component is fixed to the corresponding separation zone in a detachable way; the outer edge of the elasticity movable component is fixedly wrapped with a steel component. The other technical proposal is that the mould is provided with a core body whose outer periphery is provided with a suspension block which is integrated with the core body; adopting the scheme, the utility model is easy to pull out the mould after injection.

Description

Make the mould of thorax in the removable sandals sole of footwear nation

The utility model relates to a kind of mould of making footwear.

The removable sandals of footwear nation can be changed footwear nation as required easily because of it, with obtain all styles of not only convenient, save money but also sandals attractive in appearance not only, therefore be subjected to people's welcome deeply.Make this sandals, need have the jockey that removably connects with footwear nation, as the direct selling vertical, "  " type pin, the T-shape groove on the sole bead with sole bead medial surface at sole bead medial surface.These jockeys are set needs injection moulding, yet withdrawing pattern is relatively more difficult after the injection moulding.

The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, and withdrawing pattern is easy to make the mould of thorax in the removable sandals sole of footwear nation.

The purpose of this utility model realizes by following technical proposals:

A kind of mould of making thorax in the removable sandals sole of footwear nation, this mould has core body and the elasticity movable part that is arranged on the described core body, described core body is divided into interval region by partition wall, close outer circumference at each described interval region has the groove of placing connector and is inlaid with magnet piece, described elasticity movable part removably is fixed on each self-corresponding described interval region in the middle, the outward flange of described elasticity movable part is surrounded by steelwork regularly, and described steelwork is corresponding with described magnet piece.

The another kind of mould of making thorax in the removable sandals sole of footwear nation, this mould has core body, has on the neighboring of described core body and the whole hanging block that constitutes of described core body.Can also be with a flexible jacket in described core body neighboring, have the projection that matches with described hanging block, on described flexible jacket, have hole or the groove of placing connector in described flexible jacket inboard.

The elasticity movable part is because of having steelwork on it, thereby held by magnet piece during thorax at the bottom of the injection moulded shoes, overcomes the suction of magnet piece during withdrawing pattern and elastic bending deflection.Another program when injection moulding, hangs with the T-shape slotware on the hanging block on the neighboring of core body, after the injection moulding, the T-shape slotware is injection-moulded on the sole bead, and hanging block breaks away from the T-shape slotware during withdrawing pattern.Be with the scheme of a flexible jacket in the neighboring of core body, flexible jacket is enclosed within on the core body during injection moulding, extracts core body after the injection moulding earlier, makes flexible jacket throw off the connector that is injection-moulded on the sole bead to internal strain then.Because like this, withdrawing pattern just is easy to after the injection moulding.

The mould of thorax in the removable sandals sole of manufacturing footwear nation of the present utility model is further described by embodiment below in conjunction with accompanying drawing.

Fig. 1 is the first example structure schematic diagram of the mould of thorax in the removable sandals sole of manufacturing footwear nation of the present utility model;

Fig. 2 is the elasticity movable part flexural deformation view of first embodiment;

Fig. 3 is the footwear nation removable sandals sole schematic diagram that has with the mould of first embodiment or thorax in the sole that the mould of second embodiment of flexible jacket makes is arranged;

Fig. 4 is the second example structure schematic diagram of the mould of thorax in the removable sandals sole of manufacturing footwear nation of the present utility model;

Fig. 5 is that the T-shape slotware hangs over the schematic diagram on the hanging block;

Fig. 6 is a T-shape slotware schematic diagram;

Fig. 7 is the flexible jacket schematic diagram of second embodiment;

Fig. 8 is the footwear nation removable sandals sole schematic diagram with thorax in the sole made from the mould of second embodiment.

Referring to figs. 1 through Fig. 3.Fig. 1 is the first example structure schematic diagram of the mould of thorax in the removable sandals sole of manufacturing footwear nation of the present utility model.This mould has core body 1 and six elasticity movable parts 2 that are arranged on the core body 1.Core body 1 is divided into six interval regions 3 by partition wall 3, has the groove 5 of placing connector 13 and is inlaid with magnet piece 6 near outer circumference at each interval region.Core body 1 usefulness steel is done.Elasticity movable part 2 removably is fixed on separately on the corresponding intervals zone 4 with pad 7 and screw 8 in the middle.The outward flange of elasticity movable part 2 is surrounded by steelwork 9, and is fixing with rivet 10.Steelwork 9 is corresponding with magnet piece 6.Materials such as elasticity movable part 2 usefulness PVC plastic plates, rubber slab, elastic sheet metal are made.During thorax 11, connector 13 is put in the ground groove 5 at the bottom of the injection moulded shoes, with polyamine fat (PU) injection moulding, injection temperature is 50 ℃.Elasticity movable part 2 is because of having steelwork 9 on it, thereby held by magnet piece 6, overcomes the suction of magnet piece 6 during withdrawing pattern and elastic bending deflection (as shown in Figure 2).Cause has such elastic bending deflection, thereby withdrawing pattern is easy to.Fig. 3 is the footwear nation removable sandals sole schematic diagram that has with the mould of first embodiment or thorax in the sole that the mould of second embodiment of flexible jacket makes is arranged.Has connector 13 in the interior thorax 11 perpendicular to bead 12.

With reference to Fig. 4 to Fig. 8.Fig. 4 is the second example structure schematic diagram of the mould of thorax in the removable sandals sole of manufacturing footwear nation of the present utility model.This mould has core body 14, has on the neighboring of core body 14 and the core body 14 whole hanging blocks 15 that constitute.Core body 14 and on hanging block 15 usefulness steels do.When injection moulding, hang with T-shape slotware 16 on the hanging block 15 on the neighboring of core body 14, T-shape slotware 16 is used plastic production.After the injection moulding, T-shape slotware 16 is injection-moulded on the sole bead 17, and hanging block 15 breaks away from T-shape slotware 16 during withdrawing pattern.Like this, withdrawing pattern just is easy to.Neighboring at core body 14 also can be with flexible jacket 18.The inboard of flexible jacket 18 has the projection 19 that matches with hanging block 15, and also has the hole 20 of placing connector 13 on flexible jacket 18.Flexible jacket 18 usefulness rubber or flexible plastic are made.Flexible jacket 18 is enclosed within on the core body 14 during injection moulding, places connector 13 in the hole 20 on the flexible jacket 18.Extract core body 14 after the injection moulding earlier, make flexible jacket 18 throw off the connector 13 that is injection-moulded on the sole bead 12 then, thereby withdrawing pattern also is easy to internal strain.
