Wuhan plastic mold customization life has a lot of supplies, large or small, simple or complex products, need to use the mold production. Many people don't know the processing technology of product materials, but they are still lack of knowledge in this area. They can't tell which products are open silica gel mold and which products are open plastic mold. It seems that there is not much difference between the two, but the difference is very big. Today, Xiaobian will talk about the difference between silica gel mold and plastic mold from the material, structure and use of mold! Silica gel mold is a special mold adhesive for making crafts. Generally, silica gel and curing agent are mixed and stirred evenly according to a certain proportion, and then solidified at room temperature or under heating conditions. It has the characteristics of high temperature resistance, corrosion resistance, strong tear resistance and high simulation precision. Silica gel belongs to thermosetting material, which is generally injection molding. The fluidity of silica gel is good, so silica gel mold does not need to use water port, and the price is cheaper than plastic mold.
With the transfer of manufacturing industry to China, China's mold industry is facing the latest opportunity. China's injection molding enterprises all say that driven by foreign investment, driven by expert technology and driven by the use demand of pillar industries, China's injection molding industry has formed a complex chain, from the inferior raw and auxiliary material industry and processing, testing equipment to the inferior machinery, automobile, motorcycle, home appliances, electronic communication, building materials and other major users, which is caused by the comprehensive development of the industry There was a red fire.
However, the international large-scale mold enterprises also exposed some achievements in the process of development. First, the scope is small, second, the technology is low, third, the scope is narrow, and the impact of plastic mold on related industries is not significant.
Traditional injection molding can usually produce millions of parts of steel tools, however, it usually takes months to manufacture the mold, and the cost is higher. But what if production needs less? This is the ideal place for aluminum molds.
Today, let's have a deeper understanding of "aluminum mold" and "steel mold". If you have no more than millions of parts, if you need to produce parts on demand in a few days, and if you want to avoid risky investment before the design of parts is really verified, then using aluminum for small batch injection molding tools may be a good choice. In the process of injection mold processing, the designers of each manufacturer will have a variety of plastic mold processing technology and design methods in Wuhan.
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 plastic mold inserts in Wuhan are in place.
The mold monitor uses the machine vision contrast function and the powerful computing speed of the computer CPU to process the image data in real time. By analyzing the images captured during the operation of the machine and intelligently monitoring the operation of the injection molding machine, it can effectively detect whether the product is qualified, and check whether there is any residue before closing the mold, so as to prevent the mold from clamping damage, its detection accuracy and the domestic The applicability of different brands of injection molding machines has greatly exceeded that of similar foreign products.
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 plastic mold custom mold protector sends a confirmation signal to feed back to the injection molding machine to start the next cycle.
Curbstone mould is a mould model for producing cement precast curbstone. Curbstone refers to the boundary stone which is made of granite or cement and used at the edge of the road. Curbstone is also known as curb or curbstone. The curbstone is the boundary line that distinguishes the carriageway, sidewalk, green space, isolation belt and other parts of the road on the road surface, which plays a role in ensuring the traffic safety of pedestrians and vehicles and ensuring the neat edge of the road surface. The curbstone is mainly cut by long strips of cement precast blocks or stones on both sides of the road. The curbstone mold is mainly used to produce precast concrete curbstone, and the material of the mold is generally divided into For plastic injection molding and sheet steel mold molding, the production principle is to pour the concrete into the plastic mold or iron mold, and then remove the mold or demould the mold after the cement solidifies. The plastic mold of curbstone mainly adopts engineering polypropylene PP injection molding, and the customized material of the plastic mold directly affects the service life of the mold.
