Abstract

The present invention relates to improved shoe tree locating and fixing device, and aims at providing easily replaced shoe tree locating and fixing device and special shoe tree. The shoe tree locating and fixing device includes a shoe tree body and an installing seat, and features the shoe tree body with clamping slots on two sides and the installing seat with corresponding clamping plate and clamping plate opening and closing mechanism and embedding blocks for fitting the clamping slots. The present invention has reasonable clamping plate structure, no need of frequent shoe tree replacement in making shoe, high shoe quality and low cost. In addition, the clamping plates set on two side of shoe tree have no influence on operation of making boots.

Description

[0001] Technology area [0002] The invention relates to an improved invention of a shoe last positioning and fastening device, in particular to a positioning and fastening device and a special shoe last which can conveniently replace the same or different specification shoe lasts. Background technique [0003] In the prior art, the shoe mold is also composed of the mounting base and the last, but this shoe mold simply fixes the mounting base and the last together. When making shoes, especially in the upper injection molding, first use plastic The shoe mold shapes the upper of the shoe, and then puts the shaped upper on the aluminum shoe mold to pour the sole. Since the upper has to be put on the shoe mold with this structure twice, the quality of the shoe is affected, and its operation It is troublesome, the shoe mold is heavy, and the cost is high. The high cost of the aluminum shoe mold makes it impossible to use the aluminum shoe mold in large quantities, and also causes t...
