Die Castings

The structure and processing of car holders castings were analyzed. Die-casting molding process scheme was established. The design of mold includes three core-drawing mechanisms. the gate of the gating system was arranged on the casting bottom surface. For economy and die easy maintenance considerations, die-casting machine, mold, and mold standard parts should be standard parts. The designs of mold gating system and non-standard pieces were completed with the aid of PROE. Proved by actual production, the mold operated smoothly, without clamping stagnation, and the production of die castings meet delivery requirements.

Double Chamber

The structure and processing of double chamber throttle valve body castings were analyzed. Die-casting molding process scheme was established. The design of mold includes three core-drawing mechanisms. Considering the large parts surface area and the relatively small wall thickness and the requirement of parting, the gate was arranged on the casting bottom surface. For economy and die easy maintenance considerations, die-casting machine, mold, and mold standard parts should be standard parts. The designs of mold gating system and non-standard pieces were completed. Proved by actual production, the mold operated smoothly, without clamping stagnation, and the production of die castings meet delivery requirements.

Die casting processing analysis was conducted and the gating system and the cooling system were designed for aluminum alloy gearbox housings. Numerical simulation software PROCAST was used to calculate the filling and solidification sequence and the temperature field of die castings. The reasonable designs of the gating system and the cooling system were obtained. The feasible die casting mould was designed and manufactured. Production trial showed that, casting molding effect is good, and there were not defects such as misrun, cold lap. After machining, there were not defects exceeding the allowed limited values including porosity, shrinkage, and slag inclusion in the products. The trial showed that the product mold design and die casting technology achieved the desired effect, which can realize batch production.

Die Castings

Die casting technology is applied widely for mass production of non-ferrous metal parts. How to guarantee the quality of die castings is always a concerned topic. A quality control system for die casting machine was developed based on statistical analysis of technology parameters. Firstly the original data is acquired from die casting machine and the technology curves are displayed. Secondly, the technology parameters are identified automatically and a database of technology parameters is established. Thirdly, a statistical analysis based on the database is performed. The statistics parameters of expecta -tion and deviation are figured out and the probability distribution diagrams for technology parameters are displayed. Finally, Tolerances for technology parameters are figured out and then the system will monitor the die casting process according to the tolerances. A practical system realization in a die casting machine is demonstrated by its monitoring interfaces. Statistical information and on-line monitoring provided by this system are helpful to guarantee the quality of die castings.

Abstract Recent research in the process of aluminum alloy die castings production, which is nowadays deeply implemented into the rapidly growing automobile, shipping and aircraft industries, is aimed at increasing the useful qualitative properties of the die casting in order to obtain its high mechanical properties at acceptable economic cost. Problem of technological factors of high pressure die casting has been a subject of worldwide research (EU, US, Japan, etc.). The final performance properties of die castings are subjected to a large number of technological factors. The main technological factors of high pressure die casting are as follows: plunger pressing speed, specific (increase) pressure, mold temperature as well as alloy temperature. The contribution discusses the impact of the plunger pressing speed and specific (increase) pressure on the mechanical properties of the casting aluminum alloy.

An efficient and low-cost aluminum alloy uniform solidification control technology, namely, air-cooled stirring rod (ACSR) process, has been developed for preparing large volume semisolid slurry. The semisolid slurry preparation process is connected with the die-casting machine to form multiple integrated intelligent rheological die-casting production lines for the efficient preparation of rheological die-casting of large-scale thin-walled aluminum alloys. At present, the ACSR process can produce 40 kg of large-volume semisolid slurry with a solid phase ratio of 25% to 35% within 30 s. This rheological die-casting process has been industrialized for the preparation of high-quality aluminum alloy large-scale thin-walled parts, such as new energy vehicles and 5G communications. Typical products produced by this process include heat dissipation housings for 5G communications, filter housings, antenna chassis and three-electric structural shell, end cover, and ABS system valve body for new energy vehicles. Compared with traditional die castings, aluminum alloy castings prepared by the new process not only have fine and spherical microstructures, good surface quality, and fewer internal pores but also enjoys more excellent mechanical properties and thermal conductivity.

This paper introduces a die-casting mold design process. On the basis of the shape of Car oil pump support, central of castings’ side face was selected as the mold joint; due to the design requirements of pouring system, we chosen bias running system. Castings’ size was calculated by requirement of die casting machine, then accomplished designs of molding and structure’s components. Because through holes which on the side face of castings are not deep, angular pin core puller is competent, at last, the final assembly of the mold and the simulation is completed.

Based on the soft of FLOW3D, the numerical simulation was study the effect of runner-reduction ratio on the dispersing uniformity of added powders inside alloy melt. The parameters studied were gating shape and reduction ratio in cross section area. The results revealed that dispersing uniformity of powders, the flat gating system is better than the comb one, and the best dispersing uniformity was achieved when the reduction ratio was up to 50%.
