Description
Technical Field
The invention belongs to the technical field of die casting dies, and particularly relates to a double-center casting die-casting three-plate die.
Background
In recent years, along with the rapid development of the automobile industry, the use requirement of aluminum alloy is higher and higher, the quality requirement of products is also more and more strict, and in the production process, the high speed, high temperature and high pressure of molten metal often cause erosion and thermal fatigue cracking of a die, and cast parts are enabled to ascend to form raised spots, deeper holes and the like, so that the production cost is increased. In 2016I developed a V8 engine chain cover shell, found in the mould production that because the product structure was special, the inner gate directly punched the sealing strip mounting groove of product was surveyed, caused the mould here position too early crazing to cause the bellied crazing line that has formed on the product, because here is the installation sealing strip, if there is crazing line on the product, can have serious influence to the sealing of product, so have strict demands to the foundry goods surface quality here. Therefore, the casting method can only adopt a die-casting three-plate die in a central casting method, but a double-window structure of a product can not be found to use a conventional single-point central casting method based on product characteristics.
Disclosure of Invention
Based on the defects, the invention provides a die-casting three-plate die, wherein a double-center casting mode is adopted in a casting mode, and the die opening action is accurately controlled.
In order to solve the problems, the invention adopts the following technical scheme:
