Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy low-pressure casting metal molds, in particular to a riser insulation sleeve of an aluminum alloy low-pressure casting mold. Background Art
[0002] Low-pressure casting is a commonly used casting method for aluminum alloy casting. Low-pressure casting of aluminum alloy requires the use of low-pressure casting molds. Riser refers to the supplementary part attached to the top or side of the casting to avoid defects in the casting. In the casting mold, the cavity of the riser is a cavity for storing liquid metal. It supplies metal when the casting is formed, and has the function of preventing shrinkage cavities, shrinkage, exhaust and slag collection. The main function of the riser is to compensate for shrinkage.
[0003] The existing aluminum alloy low-pressure casting mold riser insulation sleeve device is mainly used in aluminum alloy low-pressure casting. Due to the large local wall thickness in many places, it is impossible to achieve a sequential solidification state, and it is necessary to add a riser for shrinkage compensation. The riser must be painted on time during the casting process, which is troublesome. The paint falls off or is poorly painted, which affects the shrinkage compensation and easily causes shrinkage products to leak during pressure inspection, resulting in low pass rate and increased costs.

[0010] As a preferred technical solution of the utility model: a handle is fixedly installed on the outer side of the storage frame.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The aluminum alloy low-pressure casting mold riser insulation sleeve is used in combination with an aluminum silicate fiber riser sleeve and a high-temperature adhesive. The aluminum silicate fiber riser sleeve can be firmly bonded to the inner wall of the metal mold riser by the high-temperature adhesive, resulting in greatly improved thermal insulation, good shrinkage compensation effect, effective control of shrinkage, greatly reduced pressure detection leakage rate, improved pass rate, and reduced cost.
[0013] 2. The aluminum alloy low-pressure casting mold riser insulation sleeve is used in conjunction with a reset spring and a storage frame.
