AI Technical Summary

Technical Problem

After the existing sole foam molds are fastened, the upper template and the lower template are subjected to force at only two ends, which causes the mold cavity to be easily deformed during the foam expansion process, resulting in uneven distribution of the sole thickness and reducing production quality.

Method used

Design a sole mold with uniform stress, by setting extension seats on the rear and left and right sides of the lower template, and hingely buckle the assembly on these extension seats. When the upper template is clamped with the lower template, the buckle assembly flips and buckles. On the upper end surface of the upper template, ensure that the mold can be subjected to a uniform force after the mold is closed.

Benefits of technology

Through uniform stress, the mold cavity is prevented from deforming during foam expansion, ensuring uniform distribution of the sole thickness, improving the production quality of the sole, and enhancing the stability of the mold through the transmission mechanism and locking device.

[0002] In the existing sole foaming mold, when in use, the machine applies pressure to squeeze the high-temperature gelled raw material into the mold cavity of the lower mold, then the upper mold and the lower mold are molded together, and finally the raw material is formed in the mold body by the foaming effect of the raw material itself.

[0003] However, after the mold is buckled, the upper and lower molds are only stressed at both ends. The squeezed raw materials can easily cause the mold cavity to be squeezed and deformed during the foaming and expansion process, resulting in uneven force on the upper mold, which in turn leads to uneven distribution of sole thickness in the mold cavity, reducing the production quality of the sole.
