Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods. In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. So how much do you know about its maintenance knowledge? Let’s follow the mold maker editor to have a simple understanding!
1. After the mold is used for a long time, the cutting edge must be sharpened, and the cutting edge surface must be demagnetized after grinding, and it cannot be magnetized, otherwise it is easy to cause blockage. When the mold is in use, it is necessary to make detailed records, count its use, care (lubrication, cleaning, rust prevention) and damage, based on which parts and components have been damaged, and the degree of wear, so as to provide information on finding and solving problems. And the molding process parameters of the mold and the materials used in the product to shorten the trial run time of the mold and improve production efficiency. The various properties of the mold should be tested under the normal operation of the injection molding machine and the mold, and the dimensions of the molded plastic parts should be measured. The current state of the mold can be determined through this information, and the cavity, core, cooling system, and According to the information provided by the plastic part, the damage of the parting surface, etc. can be used to determine the damage state of the mold and the repair measures.
2. Springs and other elastic parts are easy to be damaged during use, and usually break and deform. The method adopted is to replace. In the process of replacement, you must pay attention to the specification and model of the spring. The specification and model of the spring are confirmed by the color, outer diameter and length of the three items. Only when the three items are the same can they be replaced. The quality of imported spring is better.
3. The punch is prone to breaking, bending and gnawing during the use of the mold, 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 the size of the working part, the size of the installation part, and the length.
The above is a brief introduction of mold maker editor's knowledge of mold maintenance, you can learn more.
