Embodiment 1

[0057] Foam vulcanization molding rubber health care shoe sole in the double density forming mold of the present embodiment, as figure 1 , 2 As shown, it includes a high-density outer layer 61 and a low-density inner layer 62, which is an integrated structure that is released from the same mold; the materials of the high-density outer layer 61 and the low-density inner layer 62 are high-density rubber and low-density rubber respectively. The low-density rubber is made by adding a foaming agent to the high-density rubber after foaming, and the dual-density injection in-mold foaming molding production system is used to complete the double-density rubber injection, foaming and vulcanization processes in one mold. Effectively avoid the circulation of products in each process, thereby reducing production costs. The density ratio of the high-density outer layer 61 and the low-density inner layer 62 can be 2:1, wherein the density of the high-density outer layer 61 is 1000kg / m 3 . ...

Embodiment 2

[0059] The foaming and vulcanization molding rubber health-care shoe sole in the double-density forming mold of the present embodiment has the same basic structure as that of Embodiment 1, and the improvements are as follows:figure 1 , 2 As shown, a spring support 63 is embedded in the low-density inner layer 62 to play the role of skeleton support. The spring elasticity can be selected to be consistent with the elasticity of the low-density rubber to strengthen the support strength of the low-density inner layer 62 and slow down the low-density inner layer. 62. Elastic attenuation caused by frequent deformation. In the vertical distribution, 5 springs can be distributed. Cooperating with the direction of each toe, it can coordinate the rich vertical veins of the feet and play an effective role in massage and health care. The spring supports 63 diameters Slightly smaller than the thickness of the low-density inner layer 62 to avoid the hard contact between the sole of the foot ...

Embodiment 3

[0061] The foam vulcanization molding rubber health-care shoe sole in the double-density molding mold of the present embodiment is used to produce the basic structure of the double-density molding production system injected into the rubber shoe sole. The improvement is as follows: image 3 As shown, the injection device 2 in the double-density injection in-mold foam molding production system includes a hopper 21, an injection cylinder 22, a plasticizing injection screw barrel 23, an injection seat moving cylinder 24, a pre-injection chamber 25, a rubber plastic chemical machine 26, material switching oil cylinder 27, injection head 28 and material switching switching valve 29; the feeding hopper 21 communicates with the beginning of the plasticizing injection screw barrel 23, and the plasticizing injection screw barrel 23 is fixed on the end of the injection oil cylinder 22 side; the plasticizing injection screw barrel 23 and the discharge port of the rubber plasticizing machin...

Abstract

The invention discloses a double-density molding in-mold foaming vulcanization molding rubber health sole and a production technology thereof, and belongs to the technical field of rubber sole products. The molded rubber sole comprises a high-density outer layer and a low-density inner layer, and is of an integrated structure removed from the same mold; materials of the high-density outer layer and the low-density inner layer are high-density rubber and low-density rubber correspondingly, and the low-density rubber is prepared by adding foaming agents into the high-density rubber and foaming;spring supports are further embedded into the low-density inner layer to play roles of skeleton support and massage health care, and the elasticity of the springs can be selected to be consistent withthe elasticity of the low-density rubber to strengthen the support strength of the low-density inner layer; and the double-density molding in-mold foaming vulcanization molding rubber health sole isprepared by adopting a double-density injection mold in-mold foaming production system to finish the double-density rubber injection, foaming and vulcanization processes in a mold, so that the circulation of products in each process can be effectively avoided. According to the double-density molding in-mold foaming vulcanization molding rubber health sole and the production technology thereof, theproblems of insufficient elasticity of rubber soles, separate processes of injection, foaming and vulcanization of double-density soles, energy consumption, time consumption and high cost are solved.

Description

technical field [0001] The invention belongs to the technical field of rubber sole products, and in particular relates to a foaming and vulcanization molding rubber health-care sole in a double-density forming mold and a production process thereof. Background technique [0002] Shoes are an indispensable necessity in daily life. According to different functions and appearances, there are various types on the market. However, no matter how the appearance of shoes changes, the most important thing is to wear them comfortably and provide sufficient protection for the feet. important. Modern people often need to walk or stand for a long time, whether for work or leisure, and the feet support the entire weight of the human body. After a long time of use, the feet are prone to soreness and even plantar fasciitis. Therefore, a pair of Comfortable shoes are the best aid. [0003] Rubber soles are widely used in sports shoes and leather shoes, and have also been recognized. In orde...
