Press machine and template module
From: Hua Can Shoe Machinery Co.,Ltd Post date: 2018-04-14


The gluing press fixture is divided into three types according to the structure of the machine: vertical pressure template, vertical and horizontal pressure formwork, and integral molding template. The first two kinds of formwork and modules of different sizes and shapes make up the surface of the outer bottom, and the latter is made of the same convex or concave shaped surface as the bottom of the outer bottom.

Vertical compression templates and modules are made up of front template, combined template, heel module and high heel module, respectively. The semi-finished products of templates and modules are generally provided by shoe manufacturers, and the contact surfaces between templates and shoe soles or heels are made up of shoes factories, which are arranged as follows. Step 1: install and adjust the relative position of the template and module to the press bed, and adjust the angle of the front template and the rear module according to the seesaw of the sole and the shape of the heel, so that the shape of the plate contact with the sole is basically the same. The second step: according to the underline of the sole on the template, according to the shape and size of the large sole, the seesaw track is drawn on the side of the template, which is used as a surface sign to make the contact between the shoe sole and the sole. Third step: grinding the template surface to remove the template from the press bed, according to the sole or shoe last longitudinal and transverse surface, according to the line trace on the template, grinding the surface of the template on the sand turbine. For the accuracy of the surface, it can be tested while using the shoe last chassis while grinding. The fourth step is to fix the template and module on the press bed again, and use the sole to detect the shape of the template and the surface of the module, so that they are in good contact and should be carefully trimmed when necessary.

The vertical and horizontal compression templates and modules are composed of the bottom vertical template, the front horizontal module, the rear horizontal module, the lateral horizontal template and so on, forming a wall compression template. When the wall shaped outer bottom is combined with the adhesive pressure of the foot, the inner arc of the module and the inner arc should be in accordance with the outer arc of the front and back walls of the shoe sole respectively, making the adhesive surface produce uniform pressure; the side template and the bottom template are combined mechanisms to automatically form the surface of the side edge (inner and outer arms) and the bottom, forming the horizontal and vertical sides. The adhesive force of the direction.  The module and the template are plastic molding for rubber and plastic materials. The moulds of the module are designed and made according to the shape of the front and rear of the sole. The moulds of the template are not designed according to the shape of the sole because of the fixed shape and size of the formwork. The process of making the front and rear modules, that is, the process of molding and molding, is as follows. The first step: the structure of the mold is different from the model of the mechanical wall adhesive press. The shape and size of the module are different. When the mold is designed and made, the structure and size of the mould must be determined according to the shape of the module. The mold structure generally comprises a bottom plate, side plates, upper plate, etc. the last. The last die or the last die is fixed on the floor. The side plate forms the mold cavity of the module from the four directions and the front and the back, and the upper plate compacts the vulcanized material from the top down. The second step: make the last die here modeling is a key part of the decision module cavity, must be in accordance with the shoe making. Taking the middle shoe last, the front last die is made according to the arc of the shoe last, and the last die is made according to the arc of the rear. It is necessary to trim its arc with the concrete shape of the outer bottom, in order to make the cavity accurate. Production can be made of wood, and then cast aluminum parts, milling, grinding, polishing and processing. The shape and size of other parts of the last mold can be made according to the parts drawing of the module, such as height, width and related transition surfaces. The third step: after molding of the module before and after the compression molding, it can be molded on the flat press forming machine. After the molding of the front and rear modules, the inner arc should be in accordance with the shape and size of the front or rear of the sole, and the surface should not have the quality defects, such as bubbles and loss of glue.

Integral molding template: This stickiness compacting formwork is characterized by the pressure of all adhesive surfaces on a template when adhesive pressure is combined with the outer bottom; once the surface of the template and the outer bottom is determined, the template is only suitable for a sole; as long as the hardness of the template is right and the cavity surface is correct, the bonding strength is correct. It is guaranteed. There are two ways to make templates, one is manual production, the other is shoe carving machine. Two The steps made by hand are as follows. The first step is to make the rubber plate with small elasticity and medium hardness by making the contour outline, and make the maximum outline of the template according to the bottom outline of the large sole, and then the blank of the template. The length and width of the template should be larger than that of the sole, and the thickness should not be less than the thin one. When the thickness of the rubber sheet is insufficient, it can be thickened and thickened. The second step is to scribe and process the longitudinal surface, and line the template according to the longitudinal surface of the large outer bottom surface, and to process the longitudinal surface of the template according to the line. Surface machining can be grinded on a sand turbine. In order to accurately detect the shape of the surface, the outsole can be glued to the shoe last chassis to reduce the elastic deformation of the outsole. The third step: the transverse arc on the vertical surface of the longitudinal surface and the transverse arc on the shoe last chassis are easily ignored when the template is processed. This will seriously affect the pressure uniformity and bonding strength of the adhesive pressure. When grinding the cross arc, it is better to use the flexible shaft grinder and drum wheel to make the cross arc more accurate. In particular, the transverse arc of the force part of the outsole edge and the help foot must be tested with the shoe last chassis while grinding. The fourth step is to polish the heel surface. There are many kinds of heel parts, especially the shape of women's heels. In order to improve the adhesion strength of the heel, the shape of the template must conform to the shape of the heel.
