Gating system design and related tips and precautions such as gates, gate bushings, locating ring and pull material pin design, cooling system design ejection system design skills, relevant standard parameters such as thimble, flat roof, Secretary extinguishers 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 ^ plastic mold standard components such as opening and closing, guide pins and bushings, support columns, spacing bolts and springs back to move the needle meaning given molded structure forming mold structure refers to the relevant parts molded 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. 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, will be cast in the form of system-related components, structure and technical parameters are introduced. Direct gates gates are typically used directly deep and large parts of the barrel pu plastic materials, such as living in a common plastic bucket. Figure 2-10 is a schematic diagram of a direct-gate. As can be understood from the figure, the pressure loss of this type of gate, quickly filled cavity, and simple processing; drawback is near the gate stress large plastic materials peek at the product surface will leave visible traces of plastic gate material, thus affecting the appearance of the plastic material pc, and the need to manually remove the gate. Liquidity transparent material is poor, if the ordinary side gate way, it is easy to produce jet marks near the gate, if the fan gate into the plastic, you can effectively reduce the generation of jet marks. Rectangular side gate is a large outlet mold of most of the way. Shows a typical side gate. Advantages: side gate shape is simple, easy processing, easy to remove the gate. Disadvantages: The products will leave the side of the gate marks, products and the gate can not be automatically separated. For different plastic materials, the relevant parameters are not the same gate. In the design process, the user requires a combination of materials, the mold size, and position of the flow and other factors considered.
