Problems solved by technology

[0003] At present, after the air filter tube is blow-molded, the connecting piece is welded at the position reserved on the outer peripheral surface of the air filter tube. Such a production process causes the air filter tube to be easily deformed during welding, and the welding process control is difficult. , more sophisticated equipment is needed to ensure the stability and reliability of welding, and the cost of equipment is relatively high, so the preparation cost of the air filter tube in the prior art is relatively high, and the preparation cycle is also long

Abstract

The invention discloses a mold for blow molding of an air filter pipe. The mold comprises an upper mold (1) and a lower mold (2), wherein a connecting piece (4) is embedded in a cavity of the air filter pipe, a first groove for accommodating the upper part of the connecting piece (4) is formed in a first inward concave part, and a second groove (5) for accommodating the lower part of the connecting piece (4) is formed in a second inward concave part (3); a positioning mechanism for positioning the connecting piece (4) is arranged on the lower mold (2). An insert of the mold for blow molding ofthe air filter pipe is the connecting piece (4), a vertical positioning block (8) is arranged at the upper part of the connecting piece (4), and a ball positioning piece (15) is arranged at the lowerend of the vertical positioning block (8); a horizontal positioning block (7) is arranged at the lower part of the connecting piece (4); at least four connecting holes (6) are formed in the connecting piece (4) and distributed in the positions near two ends of the connecting piece (4). Compared with the prior art, the production period of the air filter pipe can be shortened, and the preparationcost is lower.

Description

technical field [0001] The invention relates to the technical field of blow molds, in particular to a mold for blow molding an air filter tube and an insert thereof. Background technique [0002] Blow molding mainly refers to hollow blow molding (also known as blow molding), which is a method of blowing a hot-melt parison closed in a mold to form a hollow product by means of gas pressure. It is the third most commonly used plastic processing method, and at the same time It is also a fast-growing plastic molding method. The mold used for blow molding only has a female mold (concave mold). Compared with injection molding, the cost of equipment is lower, the adaptability is stronger, the formability is good (such as low stress), and products with complex undulating curves (shape) can be formed. . [0003] At present, after the air filter tube is blow-molded, the connecting piece is welded at the position reserved on the outer peripheral surface of the air filter tube. Such a ...
