To ensure that there is sufficient angular pin strength and rigidity in the structure as much as possible to increase the allowable range oblique cross-sectional dimension pin, while satisfying the following conditions typing should pin inclination angle oblique designed smaller, to avoid oblique pin deform under pressure. In order to ensure the angular pin in the mold clamping can be reset to a predetermined position, should be done on the ramp pin positioning structure, positioning structure of a straight body stepped Formosa gpps, common types of plastic mold plastic commonly have three kinds, namely, large nozzle mold, thin nozzle mold and simplified form fine nozzle mold. These three types of mold are based formwork determined. Mold is mold technology and equipment, mold structure includes moving qe be fixed on board, people board, 8 boards, square iron, thimble plate, ejector fixing plate, plate, push plate, guide pin and guide sleeve. Common formwork form also has three kinds of Formosa s65, that is the great outlet mold, thin nozzle mold and reduced-fine nozzle mold. Direct Gate direct gates generally used in deep and large parts of the Formosa Plastics barrel m51, such as living in a common plastic bucket. Shown in 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 of the stress big Formosa, the product surface will leave a visible gate marks, thus affect the appearance, and the need for manual removal of the gate. Liquidity transparent material is poor, if the ordinary side gate way, it is easy to produce jet near the gate mark, if the fan gate into the plastic, it can effectively reduce the generation of jets marks. Rectangular side gate is a large outlet mold of most of the way. It shows a typical side gate. Advantages: side gate shape is simple, easy processing, easy to remove gate. Cons: WIP side will leave the gate marks, products and the gate does not 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, mold size, mobility and location and other factors considered.
