Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.

As shown in fig. 1 to 6, the present invention provides a slipper manufacturing apparatus for facilitating positioning of an insole.

The slipper for the slipper comprises an upper 110, an insole 120 and a sole 130, wherein the upper 110 comprises an upper surface 111 and an auxiliary connecting fabric 112, and two side edges of the upper surface 111 are respectively connected with two side edges of the auxiliary connecting fabric 112.

The slipper manufacturing device comprises a shoe tree 200 and an injection mold 300, wherein the shoe-pad 120 is installed on the shoe tree 200, the shoe upper 110 is sleeved on the shoe tree 200, the auxiliary connecting fabric 112 of the shoe upper 110 is pressed on the shoe-pad 120, the injection mold 300 comprises a lower mold set 310 and an upper mold set 320, a lower mold set 311 is arranged on the upper portion of the lower mold set 310, the shoe tree 200 is placed in the lower mold set 311, an upper mold set 321 is arranged on the lower portion of the upper mold set 320, an injection port 325 communicated with the upper mold set 321 is arranged on the upper mold set 320, when the upper mold set 320 and the lower mold set 310 are assembled, the periphery of the shoe-pad 120 is pressed on the shoe tree 200 by the periphery of the upper mold set 321 close to the bottom of the upper mold set 320, an elastic positioning protrusion 210 is arranged on the edge of the heel at the top of the shoe tree 200, when the mold is assembled, the elastic positioning protrusion 210 is compressed by the upper mold set 320, in the embodiment, preferably, a spring ejector pin is adopted as the elastic positioning protrusion 210.

In this embodiment, a circumference of the top of the shoe tree 200 is provided with a convex edge 220, the height of the convex edge 220 is smaller than the thickness of the insole 120, the insole 120 is placed in the convex edge 220, and has a certain positioning effect on the insole 120, but cannot abut against the rear end of the insole 120 when the insole 120 is put on, the upper portion of the insole 120 protrudes out of the convex edge 220, which does not affect the upper module 320 to compact the edge of the insole 120, and the height of the elastic positioning protrusion 210 when the elastic positioning protrusion 210 naturally extends is greater than the height of the convex edge 220, so as to ensure that the elastic positioning protrusion 210 can abut against the rear end of the insole 120.

In a preferred embodiment, as shown in fig. 4-6, the upper module 320 includes a middle frame 322 pressing on the lower module 310 and an upper cover 323 pressing on the middle frame 322. The lower module 310 is provided with a rotating seat 324 through a horizontal rotating shaft, the middle frame 322 is composed of two half frames which are arranged in bilateral symmetry, one ends of the two half frames are respectively arranged on the rotating seat 324 through a vertical rotating shaft, the inner edges of the lower sides of the two half frames are respectively provided with an inner convex edge 3221, and during injection molding, the inner convex edges 3221 of the two half frames are pressed on the periphery of the insole 120. One end of the upper cover 323 mounts the lower module 310 through a horizontal pivot.

Because the bottom of the upper module 320 is pressed on the periphery of the insole 120 close to the periphery of the upper die, and the upper die cavity 321 in the upper module 320 is slightly smaller than the insole 120, so that the injection molded sole 130 is smaller, in order to solve the above problems, the inner edge of the bottom of the middle frame 322 of the upper module 320 is provided with the inner convex edge 3221, and the periphery of the insole 120 is pressed through the convex edge 220, so that the requirements of sealing without glue leakage and the size requirement of the injection molded sole 130 can be met, after the injection molding is completed, the convex edge 220 can be clamped between the insole 120 and the sole 130, and in order to facilitate demolding, the middle frame 322 of the present application adopts the design of two half frames, when the die is closed, the two half frames are firstly rotated towards the middle to form the middle frame 322, then the middle frame 322 is rotated downwards, so that the inner convex edge 3221 is pressed on the periphery of the insole 120, and finally the upper cover 323 is covered, when the demolding is carried out, the upper cover 323 is firstly opened, then the two half frames are rotated towards two sides to open the middle frame 322, this prevents the shoe sole 130 from being torn when the middle frame 322 is opened.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
