Xi'an silica gel mold company in the injection molding manufacturing industry, the mold maintenance cost has been high uncontrollable eating the boss's net profit. Due to the particularity and irregularity of different products, although many mold protection measures are adopted, the loss caused by mold damage and personal injury can not be avoided, and every injury is to spend the enterprise's net profit, making people feel It hurts. When the injection molding machine opens the mold in place, the output signal triggers the mold protector, which takes a continuous image of the mold cavity and monitors whether the thimble ejects and drops the molded workpiece. When the workpiece is monitored to fall completely, the mold protector sends a confirmation signal to feed back to the injection molding machine to start the next cycle. If the workpiece does not fall or there are sundries between the molds within the set time, the mold protector will send an abnormal signal to stop the action of the injection molding machine and give an alarm.
The principle of injection molding of the insert in the mold IMD is to put the printed decorative sheet into the injection mold, and then inject the gum on the back of the molding sheet, so that the resin and the sheet can be integrated into one curing molding technology. IMD is a technology of inlay decoration at the same time of injection molding. The product is integrated with the decoration substrate, and can be decorated and printed for all three-dimensional shaped products, so as to achieve the effect of decoration and functionality.
In fact, IMD is a product made by cutting the printed film, inlaying it in the injection mold cavity and then closing the mold for injection molding. It is a combination of printing, molding, mold making and injection molding technology, and can comprehensively use plastic sheet, ink and plastic resin. The injection resin is combined with the ink layer on the back of the film, and the panel image and logo are placed between the film and the resin for injection molding. The image and logo of Xi'an silica gel mold opening will not be worn due to friction or time relationship.
In the process of setting up the detection principle system of mold protector of injection molding machine, two standard images are taken: after the mold is opened in place, before the ejector pin acts, the standard image of plastic parts after injection molding is carried on the moving mold; and the standard image of mold after demoulding and after the insert is in place, before the mold is closed.
In the inspection process of mold protector of injection molding machine, when monitoring plastic parts are used, the system takes moving mold image after the mold is opened in place, compares with the recorded standard image with plastic parts, extracts the difference between the two, so as to check whether the product has defects, burrs and other problems. Before the mold cavity is closed, the system takes the image after demoulding and compares it with the stored image of the standard mold cavity, so as to check whether there is any residual product on the mold and whether the silica gel open mold insert is in place.
As the most important molding equipment in the manufacturing industry, the quality of mold is directly related to the quality of products. Due to the large proportion of mold in the production cost of injection molding, its service life directly affects the product cost. It is an important weight for the injection molding industry to reduce the cost and improve the efficiency to improve the quality of the mold, maintain it properly and extend its service life.
In the actual production, due to the frequent replacement of molds, when the injection molding machine is running, the molds with high value in each production cycle may be damaged due to product residues or dislocation of sliders, etc., and mold protectors can effectively deal with various potential problems, so as to avoid machine repair, reduce production costs, Xi'an silica gel mold opening to improve product quality and guarantee the delivery period.
Different molds can use the same set of mold protection monitoring system, no need to add configuration, no need to re install and install quickly, only need to adjust the position of the sensor, take out the reference signal. There are many kinds of workpieces to be tested. There is no requirement for color. White or black can be tested. It is suitable for workpieces of various sizes and shapes.
Simple operation: the mold protector of injection molding machine operates in a very simple way, which can be detected only by operating a few buttons; when the workpiece is replaced, the system provides an embedded system of automatic learning mode: the excellent and rich functions are hidden in the host computer, which is easy to operate; high Integration: advanced image detection equipment and unique high-speed recognition algorithm are adopted, and the silicon mold opening makes The system has compact hardware structure and high integration.
Organosilicon products have good resistance to high and low temperature, generally can work at 180 ℃ for a long time. The silicone rubber can work for a long time at 250 ℃, and can withstand the high temperature of more than 1000 ℃. The organosilicon material has good low temperature resistance and can work at - 55 ℃. Some silicone rubbers are still elastic at - 110 ℃. Organosilicon material has good electrical insulation performance, and its dielectric property does not change dramatically with the change of temperature; its dielectric constant does not increase with the increase of frequency; it is resistant to arc, corona and leakage; it is resistant to ozone, radiation, weather and flame, so it is widely used. At present, a large number of silane coupling agents containing mercapto are used in the popular "green" tyres; polyethylene crosslinked by vinyl trialkoxysilane is used for silica gel mold opening, and its working temperature can be higher than that of ordinary polyethylene and PVC, so it is suitable for making hot water pipes, cable sheaths, etc.
