How to deal with silicone injection molding machine can not shoot glue
2022-03-11       Source:

When the equipment fails, we should know where the reason is, where the problem is causing this phenomenon, and it should be dealt with immediately, the same is true for the liquid silicone machine.


The following methods are used to deal with the inability of the silicone injection molding machine to inject glue:


1. The nozzle of the silicone injection molding machine is clogged with dirt. Check for clogged nozzles. Clean or replace nozzle.


2. Separation barrier. Remove the flange and inspect the dispenser for cracks. Replace the dispenser nozzle.


3. The glue spraying direction valve is stuck. Check whether the directional valve has 24V voltage, the coil resistance is 15-20 ohms, and the valve is blocked under normal circumstances. Clean valve or replace directional valve.


4. The piston rod of the liquid silicone machine is broken. Loosen the rubber injection piston rod tightening nut and check whether the piston rod is broken. Replace piston rod.


5. The barrel temperature is too low. Check that the actual temperature reaches the desired melting point of the material. Adjust the barrel temperature again.


6. The sealing ring of the injection piston is damaged. Check piston seals for damage. Replace the sealing ring.

The daily maintenance of the silicone injection molding machine directly affects the service life of the silicone injection molding machine. The daily maintenance of the silicone injection molding machine has a great impact on the service life of the silicone injection molding machine, including the smoothness of the normal use process.


The following are the daily maintenance steps of the silicone injection molding machine:


1. Replace the rubber seed and clean the pipes. At this time, first close the feed valve, open the discharge valve, discharge the remaining rubber in the barrel, close the discharge valve, open the feed valve, pour the cleaning solvent into the rubber storage barrel, activate the body, and press out according to the usual operation method. Solvent rinse.


2. If the air pressure intake is abnormal and water and gas are found, please remove the water in the pressure regulating filter or check whether the air pressure source is abnormal. Before using a large amount of glue for the silicone injection molding machine, please try a small amount to master the use skills of the product to avoid mistakes. When there is no problem in the test, use a double-drop glue machine or a double-liquid glue filling machine for mass production; the vacuum system performs vacuum defoaming treatment on the glue to remove the bubbles generated during the stirring process, or let it stand for 10-20 minutes before Use the air bubbles that make the air bubbles created during mixing. The more glue mixed together.


3. Please wipe the machine part regularly to improve the service life. The more the glue is mixed, the faster the reaction and the faster the curing speed. The glue is reasonably mixed according to the actual production situation, otherwise the glue will be wasted. Eliminate accidents and improve production efficiency. Today, liquid control technology and dispensing equipment are widely used in various production fields of modern industry.


4. When the machine is shut down for a long time, the power supply should be unplugged, which can not only prolong the service life of the machine, but also save a lot of electricity bills. With the rapid development of the industry, liquid control technology and dispensing equipment are also constantly developing to ultra-high-precision control, diversification and specialization. FIBC wholesale products are easily affected by ultraviolet rays during use, and problems such as aging occur. Therefore, in the production of the product, it is necessary to carry out anti-ultraviolet detection to ensure its good use effect. At present, the detection amount of liquid silicone machine is also gradually increasing.
