Die Casting Die Design Shell Distributor
Request, the distributor casting die casting mold runner system design eccentric, from pressure chamber, sprue, runner and the runner formed within the runner and the runner are set in the static mode, the runner from the small castings side wall surface into action, the design of a thickness of 2.5, the use of thicker runner and the runner design, when the filling pressure is conducive to transfer and wall thickness at the small end of the feeding. To avoid the direct impact of liquid metal core, resulting in the mucosal and core damage, the introduction of sub-surface location of the runner design a small arc. Guide the tangential inflow of liquid metal cavity. 2.4 row overflow system design because the size of side wall thickness of casting the uneven surface of the part and does not allow the processed gas larvae L, L and loose shrink larvae exist, therefore, die casting mold parting line must be set overflow and drain gas tank, overflow tank set not only to play the role of slag and feeding, but also doubles as the launch of casting, and thus, the capacity used in the design of large trapezoidal overflow; in order to ensure overflow earlier than the runner solidification, the cavity is solidified to form a molten alloy is not interlinked with the outside world and fully enclosed part of the final compaction pressure, overflow should be less than the thickness of the thickness of the runner, so the thickness is designed to overflow 2r puzzle.

Pillar, in order to ensure the big end forming well in the big end of the annular overflow port settings,[link widoczny dla zalogowanych], easy to set and exhaust residue, shown in Figure 3. Pulling distance is calculated as follows:. s pumping =. s Shift + K (2) where pumping is pumping S core distance, mm; S moved out to the length of core, mm; K for the safety factor, taking 15lnlTl. By calculating, core pulling away to take 130ITlnl. 5t hydraulic core pulling the selected Maximum Pulling distance 160l/lln, meet the requirements. 2.6 The cooling system design E2J to ensure the continuity of die casting production,[link widoczny dla zalogowanych], improve production efficiency and die-casting die inherent quality, air hole to prevent the casting, shrinkage, porosity and other defects, taking into account the larger size of the mold formed parts, in particular, the mold core temperature can easily rise in the production process, could easily lead to the mucosal,[link widoczny dla zalogowanych], strains, therefore, in order to ensure the thermal balance of the mold,[link widoczny dla zalogowanych], in the move, scheduled to die inserts and the core were set on the different types of loop water cooling system to regulate the mold temperature. Set the cooling water should be arranged as far as possible the maximum temperature in the cavity, the heat concentrated in the area, flow path to flow, and connecting waterways in the mosaic structure of the department's seal measures to prevent leakage.

Putting the location and layout shown in Figure 2.3 the design of mold materials and heat treatment forming parts (moving and stationary mold inserts, cores) and the sprue bush, runner plug material selection 4Cr5MoSiV1 quality mold steel, part rough for the forging, forming parts manufacturing process for forging a path to a stable annealing treatment of a rough shape of a finishing a quenching and tempering (44 ~ 47HRC) a fitter repairing a nitriding [Citation. 4 Conclusion 2.5 core agencies try and dust sprouts vend River main mines.
