Problems solved by technology

Nowadays, the production of shoe lasts is generally divided into forefoot and heel by cutting. During the division, the cutting surface will be uneven and the size will change, and only shoes with fixed styles and sizes can be produced. Once the shoe last is cut Can no longer carry out secondary processing to change the size and style

preparation example Construction

[0034] In order to obtain the above-mentioned two-section composite shoe last, the technical solution adopted by the present invention is a preparation method of a two-section composite shoe last, which includes the following steps:

[0035] Preparation of the last core: heat and melt aluminum or aluminum alloy into molten aluminum, then pour the molten aluminum into the inner core mold of the die-casting machine, and release the molten aluminum after the mold solidifies through water cooling mode to obtain the first core and the second last core;

[0036] Assembly: sandwich the separator between the first core and the second core, and assemble the first core and the second core through the connecting component to obtain the aluminum core;

[0037] Injection molding: add plastic material to the injection molding machine for heating and dissolving, put the aluminum last core into the mold of the injection molding machine for injection molding wrapping;

[0038] Cooling and sha...

Abstract

The invention relates to the technical field of shoemaking, in particular to a two-section type composite shoe tree and a preparation method thereof. The composite shoe tree comprises an aluminum shoe tree core, a plastic shoe tree shell and a connecting assembly, the aluminum shoe tree core comprises a first shoe tree core and a second shoe tree core, and the first shoe tree core and the second shoe tree core are connected through the connecting assembly; and the plastic shoe tree shell wraps the aluminum shoe tree core, at least one partition piece is arranged at the joint of the first shoe tree core and the second shoe tree core, and the partition piece extends out of the joint and divides the plastic shoe tree shell into two parts. The preparation method of the composite shoe tree comprises the five steps of shoe tree core preparation, assembly, injection molding, cooling shaping and finish machining. The shoe tree is arranged to be of a composite structure and can be repeatedly used and machined into shoe trees of different sizes, the utilization cost is low, and the machining cost of shoe tree blanks is effectively saved; and in addition, the first shoe tree core and the second shoe tree core are provided with the partition pieces, the shoe tree shell can be conveniently separated in the follow-up cutting machining process, the section of the shoe tree shell can be separated through the partition pieces, the section is complete, and the integrity of the appearance and the size of the shoe tree is improved.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a two-section composite shoe last and a preparation method thereof. Background technique [0002] The last is the mother body of the shoe. It is a molding mold for shoes. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits and protects the foot. Nowadays, the production of shoe lasts is generally divided into forefoot and heel by cutting. During the division, the cutting surface will be uneven and the size will change, and only shoes with fixed styles and sizes can be produced. Once the shoe last is cut After that, secondary processing can no longer be performed to change the size and style. Contents of the invention [0003] In order to solve the above problems, the present invention provides a two-section composite shoe last and its preparation method, which can effectively save the processing cost of the shoe las...
