Problems solved by technology

[0002] During the casting process of the wheel hub, due to the structural design of the product, the original riser and runner design are unreasonable, which is very easy to cause insufficient feeding, shrinkage porosity, shrinkage cavity and other defects, or even collapse, especially in castings. Thick hot joint parts, such as the periphery of the center hole of the casting, need to be drilled, and most of the center hole of the casting is affected by the hot joint, and the shrinkage is serious
Seriously affect the pass rate of castings and increase manufacturing costs. At the same time, because the hub castings are safety parts, if there is shrinkage inside the castings, there will be safety hazards in the subsequent use process

Embodiment 1

[0021] Such as Figure 1-2 As shown, the hub template of the present invention includes a template body 1, a pair of hub patterns are arranged in the middle of the template body 1, a sprue cup 3 is arranged on the upper end of the template body 1, and the lower end of the sprue cup 3 is connected to the middle Runner 8, the upper runner 4 is arranged on both sides of the upper part of the middle runner 8, the end of the upper runner 4 is connected to the riser 2, and the riser 2 is appropriately enlarged to provide sufficient feeding molten iron for the casting, which can completely improve The problem of subsidence, the riser 2 is connected with the hub shape through the riser neck 5, the lower runner 7 is set on both sides of the lower part of the middle runner 8, the lower runner 7 is connected with the hub shape, and the lower runner 7 speeds up the pouring speed, The feeding effect is improved; the periphery of the center hole of the casting needs to be drilled, and most ...

Abstract

The present invention relates to the technical field of wheel hub casting, in particular to a wheel hub pattern plate and a wheel hub casting process. The lower end is connected with the middle sprue, the upper sprue is arranged on both sides of the upper part of the middle sprue, the end of the upper sprue is connected with the riser, the riser is connected with the hub shape through the riser neck, and the two sides of the lower part of the middle sprue are set The down runner is connected with the hub shape; the center hole of the hub shape is provided with a cold iron; the invention enlarges the riser, increases the down runner, speeds up the pouring speed, improves the feeding effect, and the product is qualified The rate is high; there are few rough processing parts, only the iron supplement parts need to be processed; the cooling iron is added, and measures to accelerate the cooling of castings can be used to improve the internal shrinkage and shrinkage defects of the product.

Description

technical field [0001] The invention relates to the technical field of hub casting, in particular to a hub template and a hub casting process. Background technique [0002] During the casting process of the wheel hub, due to the product structure design, the original riser and runner design are unreasonable, which is very easy to cause insufficient feeding, shrinkage porosity, shrinkage cavity and other defects, or even collapse, especially in castings. Thick hot joint parts, such as the periphery of the center hole of the casting, need to be drilled, and most of the center hole of the casting is affected by the hot joint, and the shrinkage is serious. Seriously affect the pass rate of castings and increase manufacturing costs. At the same time, because the hub castings are safety parts, if there is shrinkage inside the castings, there will be safety hazards in the subsequent use process. Contents of the invention [0003] In order to solve the deficiencies in the above t...
