Automobile metal mesh plastic grating mold

Abstract

The invention discloses an automobile metal mesh plastic grating mold. The mold comprises a lower mold and an upper mold; the lower mold comprises a lower mold core and a lower mold core insert, wherein the lower mold core is provided with a framework connecting lower cavity and a metal mesh lower cavity, a metal mesh positioning rubber mat is arranged on the metal mesh lower cavity, an outer frame framework lower cavity is formed between the outer edge of the upper end of the lower mold core and the inner edge of the upper end of the lower mold core insert, and the lower mold core is providedwith a lower sealing rubber strip; and the upper mold comprises an upper mold core, wherein a framework connecting upper cavity, a metal mesh upper cavity, an outer frame framework upper cavity and an upper sealing rubber strip are arranged on the lower side of the upper mold core. According to the mold, the sealing rubber strips are arranged on the side edges of the framework connecting cavitiesand the outer frame framework cavities to control the trimming of an injection molding part; the metal mesh positioning rubber mat is arranged on the metal mesh lower cavity to position and support ametal mesh, so that the trimming problem and the positioning problem of large-wire-diameter metal mesh plastic grating injection molding machining are solved, and the product quality is improved.

Description

technical field [0001] The invention relates to a metal mesh plastic grid mold for automobiles, which belongs to the technical field of moulds. Background technique [0002] Metal mesh plastic grille is widely used in traditional fuel vehicles. It is assembled at the front end of the engine compartment. Its main function is to intake air and dissipate heat, and to prevent debris of a certain size from entering the engine compartment. Metal mesh plastic grille products are generally roughly rectangular, the main ventilation parts use stainless steel metal mesh, and the installation frame and installation parts are wrapped in plastic. Such as figure 1 Shown is a metal mesh plastic grid, which includes a metal mesh 100 , an outer frame plastic frame 200 and an intermediate connecting plastic frame 300 . [0003] Similar parts at home and abroad are assembled with injection-molded plastic frames and mounting brackets and metal mesh, or metal mesh with a wire diameter of less t...

AI Technical Summary

Problems solved by technology

[0003] Similar parts at home and abroad are assembled with injection-molded plastic frames and mounting brackets and metal mesh, or metal mesh with a wire diameter of less than 0.4mm is used for injection molding. The former assembly scheme will undoubtedly increase the processing cost, and the latter is less than 0.4mm. The ability of the product to resist splashed sand and stones is reduced, and the performance of the product is reduced

The main difficulties in the injection molding of metal mesh with a wire diameter greater than or equal to 0.4mm lie in the sealing of the plastic-wrapped metal mesh, the control of flashing and the positioning of the metal mesh in the mold
