Problems solved by technology

[0016] In this case, the fact that said penetration between the contact surfaces of the two molding materials leads to an inevitable mutual contamination of the two colors
[0017] Due to the above, the line marking the boundary between the two overlapping layers on the edge side of the sole produces blurred irregular colors which are extremely inappropriate for the aesthetic pleasing of the sole

Embodiment Construction

[0033] With reference to the drawings, the mold of the present invention has three cooperating parts as usual, namely:

[0034] -Upper cover 1, suitable for molding the first layer S1 of expandable and reticulated polyolefin material,

[0035] -Lower cover 2, suitable for molding the second layer S2 of expandable and reticulated polyolefin material,

[0036] -The middle plate 3 is suitable to be located between the two covers 1,2.

[0037] Traditionally, the cavities 10, 20 of the two covers 1, 2 face each other and the middle plate 3 simultaneously closes the cavity 10 of the upper cover 1 from below and the cavity of the lower cover 2 from above. 20.

[0038] In this conventional structure, the first characteristic of the mold of the present invention is that the cavity 10 of the upper cover 1 is connected to a channel 11 on the entire edge, which ends in a narrow groove 11a having a slightly higher height .

[0039] Similarly, the cavity 20 of the lower cover 2 is connected to the c...

Abstract

A mold devised for molding of footwear bottoms, composed of overlapping layers made with expandible reticulable polyolefin material, as well as for molding of other manufactures with monolithic structure composed of overlapping layers of expandible reticulable polyolefin materials.

Description

Technical field [0001] The patent application for the industrial invention relates to a mold used for footwear bottoms and other articles composed of two overlapping layers of expandable and reticulated polyolefin material. [0002] The design of the present invention is particularly inclined to innovate and rationalize the production mode of footwear bottoms that already exist on the market. Background technique [0003] Refer to footwear bottoms made of two overlapping layers made of expandable and reticulated polyolefin materials with different characteristics. [0004] Sometimes, the upper layer in contact with the user's foot needs to be softer and more comfortable, and the lower layer in contact with the ground when walking needs to be harder and more wear-resistant for wearing. [0005] Traditionally, special molds are used to achieve similar "double-layer" shoe soles, which are composed of two lids, each with a corresponding cavity, which is designed to interface with the inse...
