The utility model discloses a structural design, the characteristics at the bottom of the rubber secondary vulcanization that remain completely, elasticity is good and the texture is clear, the inferior bottom of plastics is at last and with the rubber bottom with the border week and the lower border of shoes portion glue together, also can remain the characteristics at the bottom of the plastics completely, the texture is light soft, plasticity is strong, maneuverability is strong, the superior etc. of mass production condition.

Description

A New Type of Combined Sole

The utility model belongs to the sole of wearing shoes, and mainly proposes a novel composite sole.

Now people wear shoes of various styles, including leather shoes, cloth shoes, sneakers, etc. Generally, the soles of sneakers or sports shoes are mostly made of rubber, which needs to undergo secondary vulcanization process, and the equipment cost is relatively high. , the process is more complicated, and the cost increases accordingly; while the soles of other materials such as plastic soles, etc., although the injection molding process is relatively simple, the equipment and process cost are all relatively cheap, but their wearing comfort and elasticity are not ideal.

The purpose of this utility model is thus produced, and a novel combined sole is proposed, which makes it light in texture, good in elasticity and has features such as strong operability and superior mass production conditions.

The technical scheme adopted by the utility model is: it includes a rubber bottom layer and a plastic sub-bottom layer. The upper surface of the rubber bottom layer made of rubber plate vulcanization process has a tenon and groove structure, and the plastic sub-bottom layer combined with the upper layer by injection molding process forms a tenon. type composite structure; at the same time, the sole will also be injection molded together with the upper at the same time.

With the structural design of the utility model, the rubber bottom layer is in contact with the ground, which can completely retain the characteristics of the rubber secondary vulcanization bottom, such as good elasticity, good shape, clear texture, wear resistance, tear resistance, etc.; The rubber sticks to the periphery and the lower edge of the upper, and the contact with the sole can completely retain the characteristics of the plastic sole, such as light and soft texture, good plasticity, strong operability, and superior mass production conditions.

Specifically, the utility model has the following characteristics:

(1) The composite shoe sole is manufactured by two processes of vulcanization and injection molding. The combination of these two processes under specific conditions makes the advantages of the two processes concentrated in one product, which is a breakthrough for the traditional method of making shoe soles. Technological progress has been achieved.

(2) The combined sole is a combination of two different material products, the combined product embodies the advantages of the two different material products, achieves an effect superior to each combined part, and improves product quality and grade.

(3) The combination adopts a dovetail structure, which can be completed by injection molding at one time, which is more conducive to industrial mass production.

(4) The bonding of the sole and the upper can be realized by injection molding, which replaces the manual operation of bonding the sole and the upper in the production of rubber-soled shoes.

(5) The production of combined sole shoes eliminates the indispensable secondary vulcanization process and equipment in the production process of rubber sole shoes, and only one-time flat vulcanized rubber soles are processed by injection molding to fully obtain the characteristics of rubber secondary vulcanization soles. Improve product quality, reduce costs, and enhance market competitiveness.

(6) Since the plastic is less elastic than rubber, the rubber sole is bounded by the omni-directional force in the horizontal direction in an area slightly smaller than itself surrounded by the tenon joint, so that the elastic energy of the rubber sole is sufficient when the footsteps rise and fall. It plays in the up and down direction, giving people a feeling of softness and movement.

Accompanying drawing is the structural representation of the utility model.

As shown in the accompanying drawings, the utility model includes a rubber bottom layer 1 made by a flat plate vulcanization process and a plastic sub-bottom layer 2 that is composited with the rubber bottom layer 1 by an injection molding process, wherein the upper surface of the rubber bottom layer 1 has a tenon groove 3 around it, formed by The mortise and tenon compound structure that constitutes the rubber bottom layer 1 and the plastic sub-bottom layer 2 is firm and reliable, and its compounding method can be: 1) Use the rubber plate vulcanization process to produce the required rubber bottom. 2) Transform the original shoe-making mould, even if it has a suitable position for placing the rubber sole. 3) Preheat the rubber sole to the same temperature as the injection mold, and place the rubber sole in the injection mold in advance. 4) Use the injection molding process to complete the combination of the plastic sole and the rubber sole (mortise and tenon structure), and at the same time complete the combination of the upper and the sole.

Claims (1)
