Direct gates gates are typically used directly deep and large parts of the barrel 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, the product surface will leave visible traces of the gate, thus affecting the appearance 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 pei plastic materials, is able to 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: simple shapes of plastic raw materials side gate pe, ease of 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. Fine fine outlet nozzle mold mold commonly used in cell phones, printers and sophisticated electronic products in China plastic materials network, fine nozzle mold can be a beautiful appearance, can be automated into production, and to ensure the accuracy of product molding size. The main characteristics of the fine nozzle mold, die structure complex, precision Gao, prone to failure, short die life. (The) processing difficulties, into pouring position is easy to adjust, easy to shape. Easy to automate production, no obvious traces of the gate, no need to manually remove the gates article. With a fine nozzle for the production of plastic mold. High (fighting) tooling costs, longer cycle times, scrap multi gating system. Fine nozzle outlet on the exterior and large, the biggest difference between the two is more than a piece of fine nozzle stripper plate mold fixed mold fixed plate and fixed template. Large outlet die only four guide posts and bushings, and a fine addition to the movable mold mold outlet side of the guide post 5 Simplified eight fine nozzle mold. Simplified fine nozzle mold commonly used in the former model has a slider mechanism of the mold, if the mold made of fine nozzle, the cost is relatively high, more waste. Course, is not scheduled to die if there is a slider mechanism can not be used fine nozzle mold. Typically, the reduced form of fine nozzle mold is relatively small, the guide column is not long, little people, such as the case of the plate thickness.
