Injection mold for instrument panel

Abstract

The invention discloses an injection mold for an instrument panel. The injection mold comprises a core plate, a cavity plate and an ejection assembly, a cavity for forming the instrument panel is formed between the core plate and the cavity plate, and a glue injection assembly is arranged on the cavity plate; the ejection assembly comprises an ejector plate, a driving oil cylinder for driving the ejector plate, and a straight ejection block and an ejector rod group which are arranged on the ejector plate, wherein the ejector rod group comprises a straight ejector rod part and a movable ejector rod part; and the movable ejector rod part comprises a mounting block, a driving block with the middle end rotationally connected to the mounting block, an ejector rod with the lower end rotationally connected to one end of the driving block and the upper end inserted into the core plate in a sliding mode, and a driving rod, wherein the driving rod is fixed to the core plate and drives the driving block to rotate on the mounting block when the other end of the driving block gets close. The injection mold has the effects that the instrument panel can be automatically ejected away from the straight ejection block through the arrangement of the movable ejector rod part, the part taking difficulty of the instrument panel is reduced, and the mold structure is simplified.

Description

technical field [0001] The invention relates to the field of molds for processing automobile parts, in particular to an injection mold for instrument panels. Background technique [0002] At present, the automobile instrument panel is an assembly in which various indicating instruments and ignition switches are installed in the cab. The instrument panel of the car is usually integrated with the instrument body, with the installation hole for installing the instrument and the defrosting air outlet for the air outlet; usually, the vehicle instrument panel is designed as a whole, and the general instrument panel is formed by integral injection molding of PP material through the injection mold . [0003] Due to the large area of ​​the automobile instrument panel, multiple reinforcing ribs are usually arranged inside the instrument panel to ensure the overall structural strength of the instrument panel. After the instrument panel is formed in the cavity of the mold, the product...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that because part of the ribs are formed in the forming grooves on the surface of the straight jacking block, and at the same time, the straight jacking rod and the straight jacking block move together when the ejector plate moves, resulting in the It is difficult to take out the ribs directly, which eventually makes it difficult to take out the product
