Abstract

The utility model relates to an injection hole device of a lifting-closing mold, particularly when modern shoe bottoms for sport shoes are manufactured, for the goal that displacement of an air cushion and an elastic object which are added in the shoes can not be caused, the shoe mold with an injection hole device is provided. When shoes are produced, the air cushion and the elastic object are arranged in a mold firstly, the air cushion and the elastic object are subjected to the clamp position of an upper mold and a lower mold, glue solution is filled into the injection hole and is heated into a mold, and the deviation phenomenon of the air cushion and the elastic object can not be caused. The fine quality of products can be guaranteed, and the yield of the products can be enhanced.

Description

Injection hole of lifting-closing mold

The utility model relates to the especially improvement of shoe-making die of a kind of mould.

Existing shoe-making die is for lifting closed molds, as shown in Figure 1, its primary structure is 1,3 formations of mould about in the of, connect in pivot button 2 modes between mould up and down, bed die 3 is for making the master mold of indent according to the footwear type, 1 of mold be corresponding male model, up and down during

mould

1,3 closures, form suitable accommodation space between two molds, the closure state of two moulds is that the latch assembly 4 of mat one side is realized.

For making more high resilience of athletic shoe sole, often when Sole moulding, install air cushion or elasticity thing therein additional now, like this, existing footwear mould is annotated glue in groove in the precalculated position that air cushion or elasticity thing is placed on bed die 3 corresponding heel positions again, after with the mold closure, in the whole process of the moulding of heating, because air cushion or elasticity thing is in light weight, omit the showy property of tool again, when glue liquid liquid injects, very easily cause the displacement of air cushion and elasticity thing, and produce substandard products.

The purpose of this utility model is: a kind of fill orifice device that installs the modified form footwear mould mould of air cushion or the unlikely generation displacement of elasticity thing at sole additional is provided.

The utility model is achieved in that it mainly is to wear a fill orifice in the mold appropriate location of lifting closed molds, cooperates a pair of corresponding key to form.

Detailed structure of the present utility model gives detailed description by the embodiment accompanying drawing that provides:

Fig. 1 is the utility model prior art structure chart.

Fig. 2 is the utility model structural perspective.

Fig. 3 is another structural perspective of the utility model.

Among Fig. 1: 1 is mold, and 2 is the pivot button, and 3 is bed die, and 4 is latch assembly, and 5 is air cushion.

Fig. 2 is the utility model structural perspective, as shown in the figure, the utility model overall structure also is roughly the mould up and down 1,2 that lifts enclosed and forms, it is mainly improved is that appropriate location (approximately being the front foot position) at mold 1 wears a fill orifice 15 and connects molds 1, and cooperating the key 16 of a correspondence to form, key can be airtight with this fill orifice 15.Wherein fill orifice 15 is roughly a taper slotted eye wide at the top and narrow at the bottom, its corresponding two side edge offers the pod 13 of appropriate depth from top to bottom, in two pods, 13 bottoms is to be connected in the same way to offer suitable translot 14, the shape of this key 16 is to cooperate fill orifice 15 and design, it roughly also is a bullet, its external diameter is substantially equal to fill orifice 15 internal diameters, when key is inserted fill orifice 15, can form closed closely, in each prominent tool one abaculus 12 of its corresponding both sides upper limb, the turn-button portion 11 of the hand application of force when its apical margin then forms a confession rotation.When making sole, air cushion or elasticity thing are placed the precalculated position of bed die 3 earlier, then cover mold 1, utilize mould 1 up and down, 3 closure, air cushion or elasticity thing are formed suitable clamping location, again glue is injected mould 1 up and down from this fill orifice 15, in the 3 ccontaining empty meanings that form, then with two pods 13 of two abaculus, the 12 corresponding fill orifices 15 of this key 16, take advantage of a situation key 16 is imported fill orifice 15 inside, rotate to translot 14 directions again to pod 13 bottoms, utilize abaculus 12 and this two translot 14 to form embedding system, make this fill orifice 15 of key 16 unlikely disengagings and form air-tight state, make glue unlikely by fill orifice 15 slime fluxs, and after the manufacturing of sole is promptly finished in the moulding of heating.

In addition, the structural design that fill orifice of the present utility model cooperates with key, also can be as shown in Figure 3, make the inner edge of this fill orifice 15 form suitable negative thread 18, the outer rim of this key 16 then forms corresponding pin thread 17, after the glue perfusion is finished, utilizes the negative thread 18 of the pin thread 17 cooperation fill orifices 15 of key 16, drive keys 16 with turn-button portion 11 and revolve and be located in the fill orifice 15, reach the state of tight closure.

The utility model has the advantage of: this footwear mould with fill orifice device is provided, at the bottom of the shoemaking time, earlier air cushion or elasticity thing are placed in the mould, be subjected to the clamping position of upper/lower die, again perfusion glue and the moulding of heating in fill orifice, the phenomenon that makes air cushion and elasticity thing not have off normal produces, and has guaranteed the fine quality of product, the yield rate height.

Claims

1, a kind of fill orifice device that lifts closed molds, its structure are mainly and lift enclosed mould up and down, it is characterized in that: wear the fill orifice of a suitable shape in the appropriate location of mold, and cooperate the key of a correspondence.

2, according to the said fill orifice device that lifts closed molds of claim 1, it is characterized in that: said fill orifice is a taper slotted eye wide at the top and narrow at the bottom, its corresponding two side offers the pod of appropriate depth from top to bottom, in two pods bottom is to be connected in the same way to offer suitable translot, key form fit fill orifice and be designed to an external diameter and equal the fill orifice internal diameter and form close-fitting bullet, at each prominent tool one abaculus of its corresponding both sides upper limb, forming one at its apical margin can be for the turn-button portion of the rotation application of force.

3, according to the said fill orifice that lifts closed molds of claim 1, it is characterized in that: said fill orifice is that an inner edge wide at the top and narrow at the bottom has the taper slotted eye of negative thread and the key that the corresponding outer rim of a cooperation has pin thread.
