Experimental equipment for composite squeeze casting of large aluminum wheel hub
1. Large hydraulic press Composite squeeze casting is a new squeeze casting method proposed in. At present, there is no special forming equipment, but the general four column hydraulic press can be modified to realize the functions required for the composite squeeze casting of large parts. As the formed...

Process flow of composite squeeze casting
According to the definition of composite squeeze casting, the process flow of the composite squeeze casting forming method is as follows: (1) The molten metal is transferred to the holding furnace in advance, as shown in figure a); (2) Upper mold and lower mold are pre assembled, as shown...

Simulation of compound squeeze casting production logistics system
The system model of the composite squeeze casting forming system established provides the basis for the production logistics simulation of large parts. Logistics simulation technology can make overall planning for the whole production logistics system in the early stage of production, such as productivity, operation time of each process,...

Design characteristics of compound squeeze casting die
The characteristics of compound squeeze casting die for large parts are as follows: only one cavity is set in one set of die, that is, only one casting is produced at a time; No gating system; Set the shunting cone to make the large volume molten liquid flow smoothly...

Definition of composite squeeze casting
Direct squeeze casting technology has a short pressure transmission distance because the pressure directly acts on the surface of liquid metal, but the molten liquid must be accurately and quantitatively filled. At the same time, direct squeeze casting is a process of clamping and extruding after filling. For complex...

Overall scheme of compound squeeze casting die
From the analysis of key technical problems, it can be seen that the composite squeeze casting die for large parts not only has the relevant functions of ordinary squeeze casting die, but also must solve the problems of pre closing, increasing the effect of extrusion force and quantitative mold...

Overall design of compound squeeze casting forming system
At present, there are two main squeeze casting methods: direct squeeze casting and indirect squeeze casting. Researchers in various countries have conducted in-depth research on these two squeeze casting methods. The direct squeeze casting method and the indirect squeeze casting method were studied. In these studies, the size of...

Research status of squeeze casting die
The main function of squeeze casting die in the forming process is to complete the liquid metal forming and ensure the forming accuracy and part performance index. Due to the technical details involved, there are few relevant foreign materials. In China, the design of squeeze casting die has been...

Mold filling speed of squeeze casting
The composite squeeze casting method adopts the closed mold filling method, which is similar to the indirect squeeze casting. Therefore, the filling speed of the indirect squeeze casting is used as the design reference of the composite squeeze casting forming system. At present, experimental method or numerical simulation method...
