A flue mold

Abstract

The invention discloses a flue die. The flue mold comprises a die base, wherein die side plates are arranged on the two sides of the die base, the die side plates are connected and fixed with the diebase through hinges, die making steel sheets are arranged on the inner walls of the die side plates, the bottom ends of the die making steel sheets are slightly longer, and the length range of the bottom ends of the die making steel sheets is within the elastic deformation range of the die base. A flue outer die manufacturing device which is more efficient and more practical is provided, and the elastic deformation range of the die base is utilized, so that a good sealing performance is achieved between the die base and the die side plates, the number of raw materials leaked in the manufacturing process is extremely small, the manufacturing cost is saved, and the pulling strength cannot be changed in the vibration manufacturing process; and meanwhile, the side movement caused by vibrationof the die can be avoided in the vibration manufacturing process, and the deviation phenomenon ensures that the thickness of the pipe wall of a flue finished product is uniform, and the flue die can be adjusted to be suitable for building lengths of different specifications.

Description

technical field [0001] The invention discloses a mold device, in particular to a flue mold. Background technique [0002] The flue is a pipe product used to eliminate the smoke generated by the cooking activities in the kitchen or the dirty gas in the bathroom. Although the flue molds are manufactured in the same way, the consumption of raw materials, the loss of the flue mold, and the overall quality of the finished flue There is a large gap in the ratio, etc. Usually, when the mold is vibrating to make the flue, due to the different sealing properties between the corners, the leakage of raw materials through the connection gaps is also different during production, and the production cost will also increase with the raw materials. Leakage increases, and at the same time, the upper part of the outer mold is subjected to long-term vibration, and the slack of various molds is not the same. The slack will also cause the rectangular change of the finished flue as a whole, and th...

[0002] The flue is a pipe product used to eliminate the smoke generated by the cooking activities in the kitchen or the dirty gas in the bathroom. Although the flue mold is used to manufacture the flue in the same way, the consumption of raw materials, the loss of the flue mold, and the overall quality of the finished flue There is a large gap in the ratio, etc. Usually, when the mold is vibrating to make the flue, due to the different sealing properties between the corners, the leakage of raw materials through the connection gaps during production is also different, and the production cost will also increase with the raw materials. Leakage increases. At the same time, the upper part of the outer mold is subjected to long-term vibration, and the slack of various molds is different. The slack will also cause the rectangular change of the finished flue as a whole, and the flue pipe wall is uneven.
