Technical Field
[0001] The utility model relates to the technical field of plastic pipe mouth core molds, in particular to a quickly replaceable plastic pipe mouth core mold auxiliary device. Background Art
[0002] Since the early 1990s, plastic pipes have been widely used in various construction applications due to their energy-saving and environmentally friendly properties, lightweight and high strength, corrosion resistance, and long service life. Plastic pipes are formed by extrusion, and the pipe size is primarily determined by the die of the extruder. Therefore, each product specification has a dedicated die mold. Plastic pipes require different S series for different applications. For example, the commonly used S series for PPR pipes are S5, S4, S3.2, S2.5, and S25. This means that pipes with the same outer diameter can have five different wall thicknesses, necessitating the use of five dedicated molds.
[0003] When producing products of varying specifications, the core mold must be replaced according to the product size. This is labor-intensive, especially for large-diameter pipes, as the core mold is very heavy and must be replaced at temperatures of 200°C. This process requires at least two workers, and after replacement, the mold must be heated. Heating large-diameter core molds typically takes six hours, consuming significant power and impacting production schedules.
[0004] Based on the above-mentioned related technologies, the applicant believes that the existing mouth core mold is inconvenient to replace and the steps are cumbersome, which is not conducive to improving production efficiency. To address the above problems, we have launched a plastic pipe mouth core mold auxiliary device that can be quickly replaced. Utility Model Content
