Mold for forming automobile air duct and forming method

Abstract

The invention relates to the technical field of automobile part machining, in particular to a mold for forming an automobile air duct and a forming method. The mold comprises a front mold, a rear mold, a first core-pulling mechanism and a second core-pulling mechanism, the first core-pulling mechanism comprises a first driving mechanism, a sliding block and a first sliding block insert, the first driving mechanism is installed on the front mold, the sliding block is connected to the output end of the first driving mechanism, and the end, away from the first driving mechanism, of the sliding block is connected with the first sliding block insert; the first sliding block insert is matched with a mold cavity; the second core-pulling mechanism is mounted on the rear mold; and core pulling is conducted through the first core-pulling mechanism and the second core-pulling mechanism, and then mold opening of the front mold and the rear mold is conducted. Under the condition that the mold is smaller than an existing injection mold in size, the quality of the automobile air duct is guaranteed, smooth demolding of the inverted buckle position can be achieved through the demolding mode after the automobile air duct is formed, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a mold for forming an automobile air duct and a forming method. Background technique [0002] Many related products of automobiles will be produced by injection molding. With the development of social economy and the improvement of people's living standards, the requirements for the appearance of automobile products are also getting higher and higher. Since automobile products need to cooperate with each other, most There are undercuts in some products, which can make the assembly between products convenient and reliable, but the undercuts interfere with the direction of mold release during the production process. The angle of inclination is large, so the mold made is bulky and will affect the production quality of injection molding products.
