Reusable sprue with temperature test head

Abstract

The invention relates to a reusable sprue with a temperature test head. A disposable film-coated sand sprue for casting of an air compressor casing can be replaced. The sprue is characterized by comprising a reusable sprue body, positioning lugs, a shaping die, a sprue cavity, a filtering net table, a runner, a filtering net, the temperature test head, a thermocouple lead, metal elastic sheets and screws, wherein the whole sprue is in an upper-lower and inner-outer structure, and a center cavity of the sprue is penetrated through. When the sprue is used, the sprue is positioned on the die, the metal elastic sheets on the two positioning lugs are respectively in point contact with the thermocouple lead which is fixedly arranged on the die and is used for a temperature control instrument. When the temperature of molten aluminum at the runner reaches a freezing point, the die is opened by the temperature control instrument, the staying time of a shaped product in the die is accurately and effectively controlled, the product quality is ensured, the sprue is conveniently and repetitively used when the sprue is automatically separated from the product, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of aluminum alloy casting, in particular to a reusable pouring riser with a temperature measuring head used when casting a compressor shell. Background technique [0002] In order to save energy and reduce emissions, various models of automobiles are equipped with superchargers, and the demand continues to increase. However, disposable coated sand products are used for the pouring risers used in casting compressor casings, which not only wastes a lot, but also The process setting is only to set an approximate time, and it is operated by experience. After picking up the parts, it is necessary to check whether the product has shrinkage or not. The production site is only in a state of manual control. Production was out of sync. Contents of the invention [0003] In view of the above problems, the present invention provides a reusable pouring riser with a temperature measuring head, which can save costs for the produc...
