Problems solved by technology

[0002] With the development of science and technology, automobiles have gradually become a common means of transportation for people. Automobile filters are one of the components of automobiles. Generally, the casings of automobile filters are formed by injection molding through injection molds. According to the existing technology, automobile filters There are grooves on the side of the shell, and ribs and undercuts are set in the grooves. When pulling the core, the stroke is very long, taking up space and costing a lot

Abstract

The invention discloses a vehicle filter outer shell core pulling mechanism. The mechanism comprises a product; a groove is formed in the left side of the product in the product width direction; a projection and a rib position projected on the surface of the groove are arranged in the groove; and a barb is arranged on the lower surface of the projection. The mechanism further comprises a first mold core for molding the right side of the product, a second mold core for molding the groove and the rib position, and a third mold core for molding the barb; an opening groove is formed in the position, near the left edge of the product, of the first mold core; the second mold core is slidingly matched in the opening groove; the third mold core is slidingly matched in the second mold core; the second mold core can drive the third mold core to deviate from the barb during core pulling; and the first mold core drives the second mold core and the third mold core to deviate from the groove when the second mold core is deviated from the rib position and the third mold core is deviated from the barb. The vehicle filter outer shell core pulling mechanism occupies no space, and is low in cost.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a core-pulling mechanism for an automobile filter shell. Background technique [0002] With the development of science and technology, automobiles have gradually become a common means of transportation for people. Automobile filters are one of the components of automobiles. Generally, the casings of automobile filters are formed by injection molding through injection molds. According to the existing technology, automobile filters There are grooves on the side of the casing, and ribs and undercuts are set in the grooves. When pulling the core, the stroke is very long, which takes up space and costs high. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art and provide a core-pulling mechanism for an automobile filter housing that does not take up space and is low in cost. [0004] The tech...
