Detailed Description

In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below, but the present utility model is not limited thereto.

Referring to fig. 1 and 2

The shoe mold forming mold comprises a lower mold plate 10 and an upper mold plate 20, wherein the rear end parts of the lower mold plate and the upper mold plate are hinged through a hinge assembly 30, a pair of sole cavities 11 are arranged on the upper surface of the lower mold plate, exhaust channels 12 are arranged on the peripheral parts of the outer contours of the sole cavities, and the exhaust channels of the two sole cavities are communicated, so that gas in the cavities is rapid during shoe sole forming. And a matched die assembly positioning structure is arranged between the lower die plate and the upper die plate, so that displacement can not occur during die assembly. The front end parts of the lower template and the upper template are also provided with

lifting rings

13 and 21 in a staggered manner so as to respectively take the upper template and the lower template through the lifting rings.

In this embodiment, in order to facilitate the separation and hinging of the upper and lower templates, the hinge assembly includes a pair of hinge sleeves 31 fixed at the rear end of the lower template, ear plates 32 are respectively fixed at two sides of the rear portion of the upper template, through holes 33 for passing through the pin shafts and matching with the hinge sleeves are formed in the ear plates, so that the upper and lower templates are hinged through the pin shafts, and the upper and lower templates can be separated after the pin shafts are removed.

In this embodiment, in order to better achieve communication between the two vent channels, the two vent channels are communicated with each other through a pair of communication grooves 14 provided at an upper surface of the lower die plate at intervals. The two exhaust channels are provided with air outlet grooves 15 penetrating out from the side edges of the lower die plate so as to exhaust the air in the die cavity.

In this embodiment, for better rapid exhaust, the air outlet grooves are arranged at intervals along the length direction of the lower die plate.

In this embodiment, in order to realize the mold closing positioning of the upper mold plate and the lower mold plate, the mold closing positioning structure includes a positioning column 16 disposed on the upper surface of the lower mold plate, and a positioning concave portion 22 matched with the positioning column is disposed on the lower surface of the upper mold plate; the two sides and the front end of the lower template are respectively provided with a positioning block 17 protruding upwards, and the two sides and the front end of the upper template are respectively provided with an avoidance notch 23 matched with the positioning block. Therefore, the die assembly positioning of the upper die plate and the lower die plate is realized through the double matching of the positioning column and the positioning concave part and the double matching of the positioning block and the avoidance notch.

In this embodiment, the positioning column has a lower part in a shape of a truncated cone, and an upper part in a shape of a bullet so as to better match with the positioning concave part.

In this embodiment, in order to better separate the upper template and the lower template after the sole is formed, a positioning block located at the rear end of the lower template is provided with a sinking notch 18 for separating the upper template from the lower template, and the height of the sinking notch is lower than the upper surface of the lower template, so that after the upper template and the lower template are clamped, the sinking notch forms a die-opening prying opening, and the upper template and the lower template are pried open through the die-opening prying opening.

When in use, the foaming material is filled into the sole cavity, and the die assembly of the upper die plate and the lower die plate is completed. The upper template and the lower template can be locked by an externally added lock catch, so that the upper template and the lower template are prevented from being separated under the action of foaming force. And (3) electrically heating the die to foam and mold the foaming material in the sole cavity, and after cooling, prying the upper die plate and the lower die plate apart through the prying bar so as to take out the molded workpiece.
