Die-casting die and interior drawing sliding block device and die casting method thereof

Abstract

The invention discloses a die-casting die and an interior drawing sliding block device and die casting method thereof. The sliding block device comprises a compressing part, at least two driven parts and at least two sliding mechanisms. The sliding mechanisms are connected to the compressing part through the driven parts respectively. The driven parts can convert displacement of the compressing part in the first direction into displacement of the sliding mechanism in the second direction. The die-casting die can achieve that products are taken out of die cavities at the same time under the production condition of one die and the multiple cavities, so that reliability of the process and continuity of the whole production assembly line are ensured. On the premise of ensuring the production stability, the yield is improved. To-be-machined products on the inner sides of adjacent die cores can directly form molded grooves, so that the subsequent machining procedures are reduced, and the cost is reduced. As the to-be-machined products can directly form the molded grooves in an interior drawing mode, the interior quality of the products is improved, local thickness of the products is reduced, and the phenomena of pores and poor shrinkage cavities caused by thermal expansion and cold contraction of to-be-machined alloy materials are avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices, and relates to a die-casting mold, in particular to an inner drawing slider device of the die-casting mold; meanwhile, the invention also relates to a die-casting method of the above-mentioned die-casting mold. Background technique [0002] At present, for die castings with multiple grooves, the molding process of drawing sliders is usually used. Among them, one mold and one cavity is a relatively stable production method. However, in order to increase production capacity, manufacturers prefer to adopt a multi-cavity production method. However, this production method has relatively difficult process problems. [0003] like figure 1 As shown, there are two opposite mold cavities inside the adjacent mold cores. If the general slider molding method is adopted, the slider S2 and the slider S8 will not be able to separate from the product at the same time, which in turn will cause the pr...

However, this production method has more difficult process problems

[0003] like figure 1 As shown, there are two opposing mold cavities inside the adjacent mold cores. If the general slider molding method is adopted, the slider S2 and the slider S8 will not be able to separate from the product at the same time, which in turn will cause the product to fail to be removed from the mold. intracavitary extraction

[0004] In addition, due to the strict process requirements of the die-casting mold, for example: the mold temperature is as high as 200°C; the production environment of the die-casting process is poor, and processing debris such as aluminum slag can easily cause the internal slider device to be stuck; and the assembly gap is too large , there will be flashes during production, and the accumulation of flashes will cause the slider to not return in place, thus affecting the appearance of the product
