Problems solved by technology
In the existing PVC large-scale wiring groove mold, the vacuum setting adsorption capacity is weak, the parison and the shaping mold cavity are not easy to fit, and the design of the cooling water flow channel is not reasonable enough, resulting in low cooling efficiency, resulting in a poor cooling effect of the shaping mold on the parison. Poor, it takes a long time to produce qualified profiles, resulting in a lot of waste, increased production costs, and reduced production efficiency

The invention discloses a PVC large wiring duct mold. The PVC large wiring duct mold comprises a mold body used for extrusion molding, a stock mold and a water cooling box. The stock mold is used for maintaining curing molding of a molded workpiece, and the water cooling box is in butt connection with the stock mold and used for cooling and molding the molded workpiece. A molding cavity in the same shape as the workpiece is formed in the stock mold. The inner wall of the molding cavity is provided with multiple vacuum air grooves and multiple cooling water paths close to the inner wall of the molding cavity, wherein the multiple vacuum air grooves communicate with the molding cavity. According to the PVC large wiring duct mold, the structure is simple, the confluence effect is good, an extruded PVC large wiring duct is good in molding effect, PVC materials are powerfully sucked to the cavity wall of the molding cavity by arranging the multiple vacuum air grooves communicating the molding cavity in the stock mold, and meanwhile the multiple vacuum air grooves are cooperated with the multiple cooling water paths close to the inner wall of the molding cavity, so that the cooling efficiency of the stock mold is greatly improved, and then the production efficiency of the large wiring duct is improved.
Description
technical field [0001] The invention relates to an extrusion die, in particular to a PVC large wiring groove die. Background technique [0002] With the wide application of PVC extrusion products in the market, it gradually replaces the original metal products with its excellent physical and chemical properties. The PVC large-scale wiring duct is widely recognized in the market for its quick and easy installation method, as well as its excellent sound insulation and heat preservation performance, and it has a tendency to replace wallpaper and wall tiles. In order to control the size and shape of special parts, the cooling setting mold will be used during cooling. The product quality, stability and productivity in the process of processing plastic profiled materials largely depend on the shaping and cooling technology. This technology allows the profile to be lowered below the glass transition temperature, and the specific cooling process depends on many factors, such as mel...
