Problems solved by technology

[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 is out of sync

Embodiment Construction

[0010] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] figure 1 , figure 2 Including the riser body 0, the positioning ear 1, the setting mold 2, the pouring cavity 3, the filter table 4, the gate 5, the filter screen 6, the temperature measuring head 01, the thermocouple wire 02, the metal shrapnel 03, and the screw 04 etc.

[0012] Such as figure 1 , figure 2 As shown, the present invention is a reusable pouring riser with a temperature measuring head.

[0013] The reusable pouring riser body 0 with a temperature measuring head is made of ceramic material. The pouring riser body 0 includes two positioning ears 1 arranged in the middle and lower part of the outside of the body. The lower part of the positioning ears 1 is provided with a shaping mold 2. The riser body 0 is provided with a through pouring cavity 3, the lower part of the pouring cavity 3 is provided with a...

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...
