Metal molds are used in industrial production to use various presses and special tools installed on the presses to make metal materials into parts or products of the desired shape through pressure. Such special tools are collectively referred to as metal molds. All kinds of tools and products we use in our daily production and life, ranging from the base of the machine tool, the shell of the machine body, to the shell of a screw, button and various household appliances, are all closely related to the mold. . The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds.
Mold maintenance and maintenance
1: After the mold is used for a long time, the cutting edge must be sharpened. After grinding, the cutting edge surface must be demagnetized, and must not be magnetic, otherwise it is easy to cause blockage.
2: Springs and other elastic parts are most easily damaged during use, and usually break and deform. The method to take is to replace. During the replacement process, you must pay attention to the specifications and models of the springs. The specifications and models of the springs are confirmed by the three items of color, outer diameter and length, and can only be replaced if the three items are the same.
3: During the use of the mold, the punch is prone to breakage, bending and gnawing, and the punch sleeve is generally gnawed. Damaged punches and sleeves are generally replaced with parts of the same specification. The parameters of the punch mainly include working part size, installation part size, length size, etc.
4: Fasten parts, check whether the fastening parts are loose or damaged, and the method is to find parts of the same specification for replacement.
5: Pressing parts such as pressing plate, superior glue, etc., unloading parts such as stripping plate, pneumatic top material, etc. During maintenance, check the relationship between the parts and whether there is any damage, repair the damaged parts, check whether there is air leakage with the pneumatic jacking material, and take measures for the specific situation.
