Molded plastic brush assembly resolver Design and Technology

Exactly is a circle enclosing. Analyze and understand the structure of the mold for the great help. Expand the location shown in Figure 4 asked. . ] One. 2 die design structural analysis from the brush assembly can be seen as terminal 4 by welding the rotor brush in four different planes, we can imagine to die without taking into account the increase in a certain amount of difficulty processing, mold No account is as follows: (1) The small size of the structure of the middle of difficult processing cores. (2) 4 core L be a closed convex step, the distance between each step and the step shown in Figure 1 is 1.1 ± 0.02mm. At the same time must also do all the steps semicircle R0.1mm wire slot. To avoid the wire brush. Concave, convex, hollow core to be made. Taking into account the concave trough level will increase the difficulty of processing to do, so do the wire groove on the steps in the convex core, the depth of the diameter of a wire. (3) require concave, convex core with the surface better. If not sealed plastic, once deposited on the wire brush over plastic mold plastic parts when it is difficult to bring out the brush with the wire, the situation will result in broken wires. (4) In order to smooth and stripping plastic mold plastic parts after the stay in the cavity. Arts cylindrical steps plus one T Jealous 22mm × 2.5mm,[link widoczny dla zalogowanych], so that the stator and rotor terminal terminal can easily emerge from the terminal block positioning. 3 die structure (1) mold assembly shown in Figure 5. First, the parting line A-A type, cover 6, the fixed plate 7, insert (a, b), with the first ejection concave core 3 (loose). Runner runner in the condensate from the extrusion material. Continue to mold in the B-B sub-surface (the main mold parting surface) type,[link widoczny dla zalogowanych], plastic extrusion together with the cavity plate 8 inserts 11, thereby completing a plastic pressure ejection: L for the process. Figure 5 plastic molded l, 2. Inserts a,[link widoczny dla zalogowanych], b3. Concave core 4. Retaining pin.) Pillar 6. Pull cover 7. On the fixed plate 8. Cavity plate 9. Under the fixed plate】 0. Floor 11. Insert 12. Core 13. Convex core l1. Limit block (2) we can see from the product structure of components. Concave, convex core should be designed with step-shaped hollow, when the level line of the mold shown in Figure 4. Analysis of core wall thickness is. Stratified according to the steps positioning the surface of the principle of cross-disjoint, each step in a hypothetical plane, then one side of the wire are shown in Figure 6. It can be seen from Figure 6: the intersection of two wire core that is the minimum diameter of the larvae L】 a jealous 6.2mm, the core wall thickness of not less than the minimum diameter of L 1 larvae of a 6.2mm. To avoid cross-point, fixed the hole diameter 2 a 7mm. Core materials commonly used CrWMn. Quenched and tempered after quenching HRC40-45. (3) concave,[link widoczny dla zalogowanych], convex core of the design of Figure 7 is a concave, convex combination of graph core simulation, that the mold clamping state in the core of the coincidence of two. In the core to do four concave, convex, closed the stairs, steps from the difference of the height of 1.1 ± 0.02mm. At the same time in all the steps needed to do semicircle R0.1mm silk tank, considering wire concave trough level is not easy to do,[link widoczny dla zalogowanych], so the steps in the convex core made of 2 Die and Mould Technology, 2008. No. Figure 215 Figure 6 cross-stratification mm, wire brushes on the convex core location, to install more reasonable. Figure 7 concave, convex combination of core simulation of the important pieces of Figure 4, the mold processing IA-i until they 【Od + I -. . l ■ +1 O / I ● 一一 0 + I a 22A to a mold structure can be seen from the mold of focus and difficulty of processing the parts are concave, convex core processing, the two cores have a direct relationship between fit whether the excess material to the plastic parts, wire brushes spatial location. As concave, convex surface of the core requirements of the agreement with the good, machining and bench repair research work is difficult, concave, convex core parting between the ground carefully, to ensure a good fit of the surface. According to concave, convex core shape, should be processed convex core (Figure Cool

. CNC milling machining center at the core level convex surface to hole 2 - ~ 5 · omm positioning alignment, a fixture, the programming process of the step surface, to ensure dimensional accuracy. The Complete the cut. 5 Conclusion The use of plastic parts is a phenolic molding compound (PFZC4), the material is a phenolic resin and other additives and wood flour filler made by mixing processing of thermosetting molding powder, the production and processing validation, the mold structure is reasonable, plastic stripping pieces of smooth surface quality. Size, high precision, fully meet the product quality requirements. The success of the molds for the live wire brush plastic parts like forming die design and manufacturing to provide a useful reference, with some promotional value. Figure 8 convex core II4: 1
