CN105269743A - Placement mold shaping process in leather shoe production - Google Patents

Abstract

The invention provides a placement mold shaping process in leather shoe production. The process comprises mold fabrication, adjustment by use of a pressing machine, placement mold pressing, pressing and mold taking out. According to the placement mold shaping process, the mold is adopted as a fixture; a lasting semi-finished product is placed in the mold fixture and pressed by use of front, rear and middle pressing blocks of the pressing machine; and on the basis of a force transfer principle that the pressing blocks press the mold and the mold presses the product, a tip, a heel and a flank of the lasting semi-finished product are pressed into last shapes. A traditional lasting semi-finished product finishing process generally adopts such manners as manual hammer striking and ironing, requiring 3-4 operators. However, the placement mold shaping process can be completed only by one person, and labor-hours can be saved.

Description

Leather shoes produce in put mould integer technique

Technical field

The invention belongs to technical field of shoe making, relate in particular to a kind of stretching tight for leather shoes and carry out the novel technique of integer after shoe last or hat block.

Background technology

The tradition shoe last or hat block semi-finished product finishing process that stretches tight generally takes manual hammer to strike hammer, scalds pressing Peer Mode, needs operator 3 ~ 4 people.

Summary of the invention

The object of the invention is to overcome above-mentioned deficiency provide a kind of leather shoes to produce in put mould integer technique, its technological process: Mold Making ~ pressing machine adjusts ~ puts mold pressing type ~ die mould ~ depanning.Take the present invention only to need 1 people to complete, save man-hour.

For achieving the above object, the present invention is by the following technical solutions:

Leather shoes produce in put mould integer technique, comprise the following steps:

A Mold Making and finishing: adopt cast polyurethane method, parent based on the original shoe last or hat block semi-finished product that stretch tight, water and outpour inner chamber and present specification and to stretch tight the mould of shoe last or hat block semi-finished product moulding, surface, inner chamber, abutment wall height are repaired simultaneously, by footwear sizes stepping making mould; General 240 ~ 250 footwears sizes, 245 moulds, 255 ~ 265 footwears sizes 260# mould, uses 275# mould for 270 ~ No. 280

B pressing machine adjusts: the briquetting at pressing machine is forward and backward, middle abutment wall position is adjusted, and answers normal extrusion after mould is put into, and its periphery briquetting produces obviously extruded to forward and backward, the middle abutment wall of mould itself;

C puts mould and controls: be placed in by the shoe last or hat block semi-finished product that stretch tight in the mould of corresponding footwear sizes stepping, ensures that forward and backward, middle part is sturdy and rectifies;

D die mould: control die mould parameter, front and back hammer is depressed, pressure stable yields product; Front and back briquetting compresses front, heel; Intermediate pressing block, extruding flank position; Thus by briquetting to mould extruding, mould extruded product, realize product integer;

E depanning: after die mould completes, takes out product from mould, and Cheng Shuan proceeds to lower operation.

Described steps d die mould: control die mould parameter, 5 ~ 8 seconds time, pressure 3 ~ 5MPa.

Adopt technique scheme, the present invention has following advantage: the present invention utilizes mould to make jig, shoe last or hat block semi-finished product will be stretched tight as in mould jig, briquetting extruding that is forward and backward, middle part is carried out by pressing machine, utilize the power transfer principle of briquetting extrusion die, mould extruded product, the half-finished paracone of shoe last or hat block that will stretch tight, heel, flank squeeze out shoe last or hat block figure modelling.The tradition shoe last or hat block semi-finished product finishing process that stretches tight generally takes manual hammer to strike hammer, scalds pressing Peer Mode, needs operator 3 ~ 4 people.And take the art of this patent only to need 1 people to complete, save man-hour.

Detailed description of the invention

Leather shoes produce in put a mould integer technique, comprise the following steps:

A Mold Making and finishing: adopt cast polyurethane method, parent based on the original shoe last or hat block semi-finished product that stretch tight, water and outpour inner chamber and present specification and to stretch tight the mould of shoe last or hat block semi-finished product moulding, surface, inner chamber, abutment wall height are repaired simultaneously, by footwear sizes stepping making mould; General 240 ~ 250 footwears sizes, 245 moulds, 255 ~ 265 footwears sizes 260# mould, uses 275# mould for 270 ~ No. 280

B pressing machine adjusts: the briquetting at pressing machine is forward and backward, middle abutment wall position is adjusted, and answers normal extrusion after mould is put into, and its periphery briquetting produces obviously extruded to forward and backward, the middle abutment wall of mould itself;

C puts mould and controls: be placed in by the shoe last or hat block semi-finished product that stretch tight in the mould of corresponding footwear sizes stepping, ensures that forward and backward, middle part is sturdy and rectifies;

D die mould: control die mould parameter, 5 ~ 8 seconds time, pressure 3 ~ 5MPa, front and back hammer is depressed, pressure stable yields product; Front and back briquetting compresses front, heel; Intermediate pressing block, extruding flank position; Thus by briquetting to mould extruding, mould extruded product, realize product integer;

E depanning: after die mould completes, takes out product from mould, and Cheng Shuan proceeds to lower operation.

Claims (2)

1. leather shoes produce in put mould integer technique, comprise the following steps:

A Mold Making and finishing: adopt cast polyurethane method, parent based on the original shoe last or hat block semi-finished product that stretch tight, water and outpour inner chamber and present specification and to stretch tight the mould of shoe last or hat block semi-finished product moulding, surface, inner chamber, abutment wall height are repaired simultaneously, by footwear sizes stepping making mould;

B pressing machine adjusts: the briquetting at pressing machine is forward and backward, middle abutment wall position is adjusted, and answers normal extrusion after mould is put into, and its periphery briquetting produces obviously extruded to forward and backward, the middle abutment wall of mould itself;

C puts mould and controls: be placed in by the shoe last or hat block semi-finished product that stretch tight in the mould of corresponding footwear sizes stepping, ensures that forward and backward, middle part is sturdy and rectifies;
