7 common mold shaped slide plate, this type of plate structure is simple, easy to process, disassembly is also relatively simple. Slider slider plate-shaped positioning slider design is complete Pulling action should remain in a defined position, in order to ensure a smooth slider reset, installation positioning device for screws, suitable for small and medium sized slider. To take advantage of the spring and the ball positioning for the slider are small. To this end slider mechanism should use screws, for the use of springs, screws and baffles positioned for larger occasions with the slider. For the use of the bezel directly targeted by the spring, screws and baffles positioning pin movable mold oblique design, when the side wall has a concave inner product features, in addition to the use of outer slider mechanism described above, you can also use oblique pin mechanism for lateral Typing. The advantage is small in the position occupied by the mold, and can play a role in the mold thimble ejection Shihai, so widely used in the mold. Shaped structure of the small end width, not less than 5, if too small, the strength and rigidity may be insufficient Formosa, easily deformed. Should be left between the ramp and the ejector pin guide carriage plate gap 0.51X1111, the purpose is to ensure the smooth movement of the angular pin, but also facilitate the assembly. Fixed guide pin oblique oblique slide pin guide carriage and ramp pin by pin connection, commonly used in small angular pin structure. Inclined pin design elements, oblique pin design will directly affect the quality of parts, oblique pin during movement must be safe, reliable and stable. Define runner is from the beginning to the end of the main road through the gate section premises runner's role is to smooth and orderly introduction of the molten plastic each cavity. Figure 2-5 shows a large common around the injection nozzle system shunt. When there are multiple cavity mold Formosa forte, the runner will be divided into first and second runner runner. The flow cross-section in the form of channel-section runner common round and trapezoid. Among them, the circular cross-section mainly for large outlet mold and trapezoidal cross-section is mainly used for fine nozzle mold. Circular cross-section flow channel parameters: Figure 2-6 shows a circular cross-section flow path cross-sectional dimension which is generally even, cross-sectional size can be determined according to the size of the product, the greater the article, the more molten plastic flows into the desired . In order to ensure to fill the cavity in a short time, a relatively large size can be used, if the article is small, a small cross-sectional dimensions. Advantages of circular cross-section of the flow channel area is the ratio of surface area to cut the minimum friction when the molten plastic flows into the minimum, slow cooling can reduce the loss of the melting temperature, the size of the balance to maintain the pressure, and easy processing. Trapezoidal sectional flow: water mouth fine common trapezoidal cross-section flow channel, the advantages are easy processing trapezoidal section, the disadvantage is melted plastic in the runner will lose more heat. Parameter setting sprue and runner between the main channel in the front runner of different sizes path between two different streams. It shows the relationship between the main channel and large outlet diversion channel. As can be understood from the figure, the largest size 0, followed by ⑴, Bom, confused, runner diameter is generally 0.750 Formosa Plastics agent, each of the lower flow channel was 0.75 times superior flow path. Fine is a common outlet flow channel parameters, we can see the relationship between Formosa, on the lower level between the flow channel is also 0.75 times. Pouring into the gate is the last link in the system, the gate is directly connected with the mold cavity, size, form and position of a gate size required is determined according to the article shape, appearance and size.
