Embodiment Construction

[0036] exist Figures 1 to 7A driving device is schematically shown in , which is used to drive a bottom mold 1 in the forming station 2 on the round workbench of a shoemaking injection molding machine not shown here to move vertically. The forming station 2 also includes side molds not shown in the figures and a displacer 3 or ( Figure 4 with 5 ) a shoe last 4 . Bottom mold 1, ejector 3 or last 4 and side molds form a cavity for the manufacture of shoe soles. exist figure 1 A device for making outer soles is described in . The process can also be figure 2 with 3 seen in.

[0037] exist Figure 4 with 5 The outer sole has already been made. At this time, a material of another or other color will be injected between the outer sole and shoe last 4 in the cavity left, so as to make a shoe upper for connecting the outer sole and tightening on the shoe last middle layer sole.

[0038] The bottom mold 1 is mounted on a lift table 5 which can be vertically guided in a l...

Abstract

A method for forming the sealing force of an injection molding machine for producing shoes and soles is provided. The injection molding machine has at least a mould for soles to be manufactured or formed, wherein the mould is composed of a side die, a bottom die capable of moving vertically, and a displacer or a shoe last relative to a upper, wherein the displacer or the shoe last is the upper boundary of the die cavity. According to the present invention, after fitting the shoe last, or after fitting and locking the displacer, the bottom die is moved initially by a pneumatic working stroke of its cylinder assembly(bottom die cylinder), into the mold cavity filling position. Then, the adjustable and variable, additional hydraulic converter force is applied. This presses the material injected, to form the sole. The force is held until the sole becomes dimensionally-stable.

Description

technical field [0001] The invention relates to a method for applying a closing force to an injection molding machine, in particular for the manufacture of shoes, having at least one mold for the sole to be manufactured or shaped, the mold consisting of a side mold, a vertically The moving bottom mold and a displacer or a shoe last stretched on the upper form the upper mold cavity boundary. [0002] The invention also relates to a device for carrying out the method. Background technique [0003] At present, the mass production of shoes is mainly carried out by means of so-called round table machines, on which a plurality of forming stations containing moulds are arranged, each of which enters the plasticizing process after a corresponding rotation of the table and injection stations. [0004] When producing shoes with multi-layer or multi-coloured soles, first the outer layer of the sole is injection molded. For this purpose, the bottom mold moves upwards and the side mol...
