The use of cutting tool mold: cutting knife mold widely used in various types of cutting machine, the use of points are: to prevent the knife mold and other metal parts bump, keep the knife blade blade sharp and no edge and notch phenomenon; red Cutting shoes, the stroke adjustment should be accurate and reliable, not suddenly deep and shallow, to prevent cutting into the cutting board is too deep and deformation of the knife mold and blade damage; the use of double-sided blade knife blanking shoes, the machine plate hardness Shall not exceed the hardness of the cutting edge; the thickness and the number of layers shall not exceed the carrying capacity of the die, to avoid the poor return material and hit the knife mold and affect the shape and size of the shoe; die in the storage, And the load of heavy objects, so as not to deform and damage the blade; when the bulk of the bulk material, the shape of the mold should be regularly on the accuracy of the height of the parallel size of the parallelism, the blade sharp state and other key parts of the inspection and repair To ensure the accuracy of the shape and size of the shoe; it is recommended to use a special die die made of die die, because this knife has a high precision, light weight, short production cycle, can quickly adapt to changes in the characteristics of varieties The
The use of the main mold with the mold: the installation of the mold: in the mold before installation, should be proof of the mold model with the main size specifications are consistent to ensure that the main with the molding quality. At the same time to cut off the power of the device in order to install the electric tube. When installing the mold, the inner and outer molds of the left and right molds are not installed, otherwise the mold cavity will be damaged once the mold is closed. After installing the mold, to adjust the two outer mold and the mold on both sides of the opening and closing to make it equal. Mold adjustment: After installing the mold can boot to check the mold running status. Mold closed, the mold joints should be tight, the size of the outer mold should be higher than the upper mold on the plane, and uniform; especially the shape of the heel to help the foot with the main, the size should be the same with the main thickness or slightly larger The The use of mold: mold before use, to the outer mold skateboard guide and the edge of the sliding guide rail lubrication, to keep the mold movement flexibility. In use, if the main with the mold cavity placed in the unstable or not allowed, the mold opening volume should be small. If the molding conditions in the correct case with the main forming effect is poor, the mold cavity is irrational or the main shape and size is not matched, should be removed to check the mold and targeted processing.
Insole molding mold use: different structures of the insole molding mold used in different types of insole molding machine. Double mold insole mold application In the single cylinder automatic insole molding machine, forming a pair of insole at one time; single mold insole mold used in the double cylinder insole molding machine, forming an insole at a time. Mold installation and adjustment: two-model insole mold two bottom mold fixed to a floor, the bottom plate into the shoe machine installation on the positioning slot can be, because the bottom of the mold position and the bottom of the positioning surface and footwear machinery On the positioning size is very accurate, no need to adjust the positioning accuracy and fastening. While the bottom plate is inserted into the mounting groove, the positioning adjustment and the ejector bar in the bottom mold are automatically entered into the long groove of the bottom mold. Bottom die installed and then installed on the mold. The two positioning bolts of the upper mold are fitted with the floating mounting plate and the mounting groove on the molding cylinder, so long as the upper mold is inserted into the groove, respectively. It is important to note that the two upper molds must correspond to their respective bottom mold cavities, and do not make mistakes. Usually the left side of the mold surface coated with black, the right side of the mold surface painted red, as long as the upper and lower mold color the same, left and right mode position will not be reversed. The installation of the single-model insole mold is carried out separately, ie the left bottom mold is mounted on the piston plate of the left cylinder and the right bottom mold is mounted on the piston plate of the right cylinder. The upper molds are respectively installed in the holes of the fuselage beam and fixed with screws. After the mold is installed, it is necessary to carry out the molding of the insole. In the test molding, adjust the molding pressure, molding time, the number of the regulator position. Forming pressure and time, with the insole material. The position of the number adjuster is different due to the different surface of the inner cavity, so the position of the regulator must be re-determined for each change of mold. Will be molded after the end of the mold on the chassis, check the molding effect. The shape and size of the forming insole should be consistent with the shoe last chassis, especially the metatarsophalangeae and the heel site, and the metatarsophalangeal to the anterior tip is at least equal after the light pressure.
The use of the end of the mold: the correct use of the end of the mold, and forming the quality of the insole has a great relationship. When the insole shape and size and shoe last chassis is inconsistent, insole and semi-insole bonding is not strong, the bottom surface of the indentation or uneven force, should stop the operation to identify the cause. The above three abnormal phenomena are by the upper mold and the bottom mold cavity error, the position of the insole in the cavity is not adjusted or no number regulator, the mold and the bottom mold cavity surface is not smooth or cavity by Pressure uneven and other causes, should be targeted to deal with. In addition to the reasons for the mold, the molding pressure is low, two mold pressure is inconsistent, forming a short time, but also cause poor quality in the bottom of the reasons. Some insole molding machine in the pressure setting is insufficient, or in use without the pressure transferred to the working pressure, is the molding pressure of the two main reasons; two mold pressure inconsistency reasons, one mold height error , The second is the pressure of the two cylinders are not equal; manual operation of the model, forming time is not accurate or suddenly long and short, will have a negative impact on the molding effect. When found in the formation of the insole is not easy from the cavity automatically pop or not easy to remove, in addition to check the shoe-related equipment, the reasons for the mold base mold on the ejector and the mold is not smooth or residual adhesive should be the main the reason.
Outside milling edge Aids and tool use: Select the cutter and the template: Select the cutter and the template according to the outsole shape and size. The shape of the blade is consistent with the shape of the outer end of the blade, that is, what kind of blade shape will be what kind of bottom edge shape; by the shape of the template to the shape of the outsole with the same, that is what kind of What kind of outsole will be mantered by the template. Install the milling cutter and the template: Install the milling cutter on the milling cutter shaft so that the height of the milling cutter is the same as the height of the outer bottom, and if there is a high degree of error, it can be changed and adjusted on the thickness of the lower part of the cutter The Milling cutter shaft with two-axis and two-axis mechanism, single-axis only to install a cutter, two-axis can be installed two milling cutter and the shape of the shape of the outer edge of the knife. The end face of the template should be consistent with the height of the step height of the die set. When the milling groove of the milling cutter is worn, the steps of different diameters should be selected correctly to eliminate the errors caused by the tool wear. To test the outsole and adjust: check the outsole contour shape and the end face shape by examining the outsole. If there is still an error in the height of the outsole and the milling cutter, the height of the milling bracket can be adjusted so that the outsole on the outside is slightly raised or lowered until it is aligned with the milling cutter groove. Operation and use: the operation of the template and the outsole rotation, must be evenly forced hands, so that the template stable and uninterrupted in the mold on the steps of the rotation, to ensure that the end of the end of the processing quality. According to the number of milling cutter groove to determine the number of layers at the same time processing, generally one can simultaneously processing a pair or two pairs of outsole. The edge shape of the heel part can also be milled depending on the milling cutter and the shape of the template.
