Embodiment Construction

[0015] A small heel sole for injected or molded shoes, such as figure 2 As shown, it is divided into three layers in the vertical direction. The first layer is the support layer 1, which is connected to the inner bottom, and its periphery is 5-6 mm smaller than the second layer. The second layer is the reinforcement layer 2, and the third layer is the connection layer 3. The reinforcing layer 2 and the connecting layer 3 are provided with a "crescent"-shaped gap 4. After the small heel is nailed together, the first layer 1 has a gap with the inner bottom and the upper corner, which is convenient for rubber injection, and the small heel and the upper. , the inner bottom are integrated, and the surrounding "crescent" gap 4 is also injected with rubber when injection or molding.

[0016] It should be pointed out that the shape of the gap 4 is not limited to a "crescent" shape, and can be located in the reinforcement layer or the connection layer.

[0017] The size of the reinfo...

Abstract

The invention discloses a special small rear sole for injection or mould pressing of shoes. The small rear sole is characterized in that a first layer is a supporting layer and is connected with an inner sole, and the periphery of the first layer is smaller than a second layer by 5-6 mm; the second layer is a reinforced layer; a third layer is a connecting layer; an opening is formed in the reinforced layer or the connecting layer, or each of the reinforced layer and the connecting layer; after the small rear sole is nailed, gaps are formed between the first layer and the inner sole and between the first layer and an upper. During glue injection, the gap between the first layer and the upper is filled with glue, and the opening in the periphery is filled with the glue at the same time, then a net-shaped glued main body is formed, so that the glue connection between a heel rubber body and the small rear sole is improved and the glue failure phenomena are reduced.

Description

technical field [0001] The invention relates to the field of shoe processing, in particular to a special small back sole for injection or molding shoes. Background technique [0002] Injected shoes or molded shoes with traditional small heel such as figure 1 The edge shown is smooth, and the joint surface with the inner sole, heel and side foot is limited, and the connection is not strong, which makes it easy to peel off the glue. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a special small back sole for injection or molded shoes, which can reduce the phenomenon of shoe glue breaking. [0004] The purpose of the present invention is achieved in the following manner: [0005] A special small back palm for injection or molded shoes, the small back palm is divided into three layers in the vertical direction, the first layer is the supporting layer, connected with the inner bottom, the per...
