A kind of sole injection mold for shoemaking

Abstract

The invention discloses a sole injection mold for shoe making. The sole injection mold for shoe making comprises a mold body; an injection groove is formed in the mold body; popup holes are uniformly formed in the bottom of an inner cavity of the injection groove; ejecting blocks are clamped in inner cavities of the popup holes; the outer walls of the ejecting blocks are bonded with the inner walls of the popup holes; ejecting rods are fixed at the bottom ends of the ejecting blocks; the bottom ends of the ejecting rods extend below the mold body; limiting bases are fixed at the bottom ends of the ejecting rods; limiting bolts are screwed above the limiting bases; and return springs are sleeved between the limiting bolts and the ejecting blocks. The sole injection mold for shoe making is simple in structure, can eject out injected soles through the effect of the return springs and the ejecting blocks in the sole injection process without generating the bonding condition of the soles and the mold, greatly guarantees the sole quality, and improves the sole production yield.

Description

technical field [0001] The invention relates to the technical field of shoemaking equipment, in particular to a shoe sole injection mold for shoemaking. Background technique [0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change after being shaped. Heat preservation, easy to absorb moisture, etc., and at the same time, it must cooperate with the midsole, which has a braking effect when walking and changing feet, so that it will not slip and is easy to stop. There are many types of sole materials, which can be divided into natural base materials and synthetic base materials. Nat...

Problems solved by technology

[0003] In the production process of shoe soles, most of the processes are made by injection molding, which is an indispensable tool for molds. However, during the use of traditional molds, the soles after injection molding are sticky. Attachment is often not easy to take out the sole, and if the sole is taken out from the mold by an external force manipulator, it is easy to cause deformation of the sole, which seriously affects the quality of the sole
