Gating system design plastic materials pet, such as a gate, gate bushings, locating ring and pull pin design materials, techniques and considerations related to the cooling system design ejection system design skills, relevant standard parameters such as thimble, flat roof, Division tube and push the block, exhaust mechanism design ^ positioning mechanism design side parting mechanism design, such as the common type of sliders and lifters # plastic mold, such as large intakes, fine fine nozzle outlet and simplified type of plastic mold ^ commonly used standard parts, such as the opening and closing, guide pins and bushings, support columns, spacing bolts and springs back to move the needle meaning given molding mold structure forming structure refers to the related parts for molding plastic products. A simple part, if there is no side parting mechanism for forming the structure of the article will have moving parts 丨 scheduled to die benevolence. Peek plastic material when the structure is complex, shaped structure also includes a slider, lifter and core and so on. Gating system in the mold structure, gating system includes a positioning ring, sprue bushings, sprue, runner, runner, cold-slug and pull the needle material. Starting from the injection molding machine nozzle to flow into the cavity until the channel through which called gating system. In this section, plastic materials, will be cast in the form of system-related components, structure and technical parameters are introduced. Big big outlet nozzle mold mold mold, also known as the second board, commonly used in the barrel, toys, electronics products, the relatively low appearance requirements. Learn large outlet die pu plastic materials, we must first know their characteristics and common form of mold. The main characteristics of the large outlet of the mold, simple structure, easy assembly, small chance of failure and long tool life. Short cycle times and high efficiency. Low tooling costs, gate location restrictions restricted parts not easily automated, there are clear signs of the gate. Large outlet side mold structure, including fixed mold fixed plate, set the template, moving platen, square iron, thimble fixed plates, ejector plate, movable mold fixing plate, guide pillars and covers. Shown as large outlet mold, including push plate be fixed on board, moving mold fixing plate, guide pillars and covers. pvc plastic material _ Gary trade (certified) _ Baoan plastic material provided by the Shenzhen Municipal Trade Co., Gary.
