Structure of plastic AC plug mold

The structure of the plastic AC plug mold: it mainly includes a concave mold with a variable cavity composed of a concave mold combined substrate, a concave mold assembly and a concave mold combined card board, and a convex mold combined substrate, a convex mold assembly, and a convex mold combined card A punch with a variable core composed of a plate, a cavity-cutting assembly and a side-intersection combined plate. The harmonious changes of the convex and concave molds of the AC plug mold and the auxiliary molding system. It can process a series of plastic parts with different shapes and different sizes.

　　 In order to improve the function of plastics, it is necessary to add various auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., to the plastics with outstanding functions.

　　 1. Synthetic resin is the most important component of plastic, and its content in plastic guessing is generally 40% to 100%. Because of the large content, and the nature of the resin often determines the nature of the plastic, people often think of resin as a synonym for plastic. For example, compare polyvinyl chloride resin with polyvinyl chloride plastic, phenolic resin with phenolic plastic. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer, which is not only used to make plastics, but also a material for paints, adhesives and synthetic fibers. In addition to a small part of plastic containing 100% resin, most plastics, in addition to the primary component resin, also need to participate in other substances.

　　 2. Filler filler, also known as filler, can improve the strength and heat resistance of plastics and reduce costs. For example, the participation of wood powder in phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheapest plastics, and together it can significantly improve the mechanical strength. Fillers can be divided into organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, the latter such as glass fiber, diatomaceous earth, asbestos, carbon black and so on.

　　 3. Plasticizers Plasticizers can increase the plasticity and flexibility of plastics, reduce brittleness, and make plastics easy to process. Plasticizers are generally high-boiling organic compounds that are miscible with resins, non-toxic, odorless, stable to light and heat, and the most commonly used are phthalates. For example, when producing PVC plastics, soft PVC plastics can be obtained if more plasticizers are added, and hard PVC plastics can be obtained if no or less plasticizers are added (amount <10%). .

　　 4. Stabilizer In order to prevent the synthetic resin from being decomposed and destroyed by light and heat during processing and use, and to extend the service life, it is necessary to participate in the stabilizer in plastic guessing. Commonly used are stearate and epoxy resin.

　　 5. Colorant Colorant can make the plastic AC plug mold have various bright and beautiful colors. Commonly used organic dyes and inorganic pigments as colorants.

　　 6. The role of the lubricant is to prevent the plastic from sticking to the metal AC plug mold during molding, and together to make the appearance of the plastic AC plug mold lubricate beautifully. Commonly used lubricants include stearic acid and its calcium and magnesium salts. In addition to the above additives, plastic guessing can also participate in flame retardants, foaming agents, antistatic agents, etc.
