More than one mold die casting mold and repair the slider

Shao. Figure 2 mold structure die industry in 1991. No. 10. Even 128 is a course of their work: in the closed state of Figure 2,ed hardy schweiz, when the branded financial zinc alloy through the main runner, and gate were semi-circular shunt (located in the fixed-die), the pressure into the cavity, the cavity with left and right side of the core shown in Figure 3, and the dynamic cavity (Figure 4) composed of a fixed template. Open mode, the inverted core 3,5 11 through the slider 6 at the angle pin and compression spring 9 under the action rhyme, out of the castings from the golden slipper and then driven ejector l5 the casting cavity 14, top out, finally, by resetting the bar (mandrel two I) to restore in situ mandrel. At this point students die maggots falling edge of the cavity 3 in Figure 4 moving parts replacement and maintenance of dynamic model of Figure 4 from 3 small cavity is connected via screw clamp made of two identical action and then were pressed into the mold cavity moving floor Among the fixed plate 12, and the distribution of the two reservoirs in the main runner, moving mold cavity with the spirit of asking for the static fixed plate with Taiwan. Also asked in the processing of the cavity with the table all the time 'must be in strict accordance with the drawings of the dimensional accuracy and surface roughness in order to prevent damage when the product appears to be replaced and the flash. 47 out of Song Cong I glanced Joseph Yi Xiao Hang,louboutin københavn, and plastic roar 3 guillotine quiet core is fixed with screws and pressed into the side of the slider to go n, when the production of damage to the mold cavity, it can be a direct replacement of damaged core or cavity side to enhance the utilization of chess, shorten the repair period. After the operation replacement parts in the mold, and then down the damaged parts are replaced, to repair or re-manufactured spare. 3,5 in the maintenance side of the core, the first left and right side core two together, with light transmission, shading was observed at grinding and then a small Taijin Files shade at the side of the core part of the bulge so there is no light in the joints until the phenomenon. However, the appropriate size to be detected at the same time to avoid zipper does not work smoothly with the chain used in the repair parts for the conservation, but also flexibility and freedom to combine two side core, can only meet the required repair. To prevent waste. Through the replacement of wearing parts and maintenance can be for enterprises to improve economic efficiency and cost savings die mold manufacturing process ~ ~-o ∞ ~ D2 steel thermal processing performance and rhyme Cr12MoV difference Taiyuan Steel demon, Division III Court million steel mill is currently the king Internationally, the view that good hot die steel for the U.S. standard of H13, while the cold die steel, the steel is a typical D2. D2 steel in order to make the production and use of a wide range, are presented Crl2MaV D2 steel and forged steel and heat treatment performance characteristics. 1.1 1D2 characteristics of steel is 430 D2 steel with high carbon composition, high chromium, cold work tool steel in a typical actinides number. The chemical composition of the steel by the United States Iron and Steel Institute AIS [standard provisions included in Table 1. For comparison, the Chinese GB1299 - 85 of Cr12MoV steel is also included. As can be seen from Table 1, D2 and Crl2MoV in composition, D2 steel, Mo and V in the ultra-high, and this consolidated the steel actinides with performance far exceeds the 1.2 Steels Cr12MoV D2 steel, the pliers are medieval 12 Cr, so that the phase actinium store had apparently changed to s and E point to the left, aluminum and vanadium are also similar for the H1, Tong carbon equilibrium diagram of iron of a Y-tank area reduced. Chromium in the steel. The formation of (Cr · le). . c (Cr · Fe) 7C3, and (Cr-FejC three skeleton http 48 Notes on Table 1 chemical composition of ancient elements of profit C1.40DB11601. {5Crl2MoVIf1.7OMnfSiJCffMoV {O.3003Oll1.fl000 'IiI1If} 080. -5. 10. 53.0. II_ll1. carbide. because in the middle of the initial D2 carbon steel ledeburite, so D2 belong to the actinide and Leydig Cr12MoV off Cuba because the steel like steel has more carbon saddle, steel can be heated in a large number of quenching solution into austenite,abercrombie outlet, resulting in high hardness Markov break tempering after quenching, since a large number of Mi proud of martensite distribution of precipitation of carbides,christian louboutin, the hardness is high [(Cr · Fe) Cs is about the hardness HV2300], thus increasing the wear resistance of steel. On the other hand, addition of chromium steel,ed hardy suomessa, steel, isothermal transformation curve strongly shifted to the right, thereby increasing the hardenability of guillotine. Point Ms point reduction, the residual austenite after quenching actinides increases the amount of deformation of the steel after quenching a small volume. tooling industry 1901.No.10 core 128
