Mold protection Because the mold has unique features such as delicate precision and vulnerability, it is very important to carry out the safety protection of the mold. The following are summarized in the following aspects:
Anti-rust: prevent injection molding machineAnti-collision: Prevents the mold from crashing due to cracks in the ejector pin and failure to retreat into place.Detachment: Prevent mold burr caused by cloth/material/hand/water nozzle/knife.Missing parts: Prevents the mold from being damaged during use of the mold due to lack of parts such as tie rods/washers.Anti-pressure: Prevents the mold from being crushed due to mold clamping still caused by residual product.Anti-pressure: to prevent the mold from damage caused by excessive pressure protection. Among them, a high proportion of die damage due to the breakage of the thimble, the absence of the ejector pin in place, the residual product of the die, and the lack of accessories are frequent, and therefore more than 85% of the die damage is caused by this reason. Mold maintenance costs are generally high, so how to avoid such a situation is directly related to the interests of the injection molding industry.
In order to prevent production delay caused by mold damage, as well as high maintenance costs, but also to better save labor resources, some companies have used machine vision technology to develop a product called "mold protector." Mold monitors, or mold protectors, also known as mold electronics, can effectively protect valuable molds. Injection molding machine mold protection system, installed in the injection molding machine, you can directly check the product is qualified, and check whether there is residue before clamping, in order to prevent mold folder damage. During the operation of the injection molding machine, in each cycle, the expensive molds may be damaged due to plastic residue or the misalignment of the slides, so as to prevent these conditions from occurring, and automatically prevent mold closing and alarm when an abnormality occurs. If you do not take effective mold protection and cause mold damage, we give you the following suggestions:Mold repair precautions: When removing the mold, avoid bumps and move smoothly. Anti-rust mold need to reduce the mold temperature to 40 degrees or less; Thoroughly inspect the mold and perform rust prevention: Carefully wipe the moisture and debris in the cavity, core, ejection mechanism, and row, and apply mold rust inhibitors and grease.
Mold maintenance In the process of continuous operation of the mold, due to problems such as wear of parts and components, deterioration of lubricant, leakage of water, and crushing of plastic materials during the movement, mold maintenance is required. Mold maintenance is generally divided into routine maintenance and mold maintenance.Routine maintenance1. Regular rust removal (appearance, PL surface, cavity, core, etc.) 2. Regular re-lubrication (extrusion mechanism, row position, etc.) 3. Regular replacement of wearing parts (rods, bolts, etc.) 4. Other places that need attention The maintenance of the lower mold requires the professional maintenance personnel to remove the mold and then perform professional maintenance and repair on the mold cavity and thimble.
