Abstract

The invention discloses an automobile handle lever forming structure. The structure comprises a fixed module and a movable module, wherein the fixed module comprises a fixed mold plate and a fixed mold core arranged on the fixed mold plate; the movable module comprises a movable mold insert, a handle lever injection molding cavity is defined among the movable mold insert, a fixed mold insert and the fixed mold core, a side pulling core is arranged in the handle lever injection molding cavity, and a positioning hole matched with the end part of the side pulling core is formed in the fixed moldcore; the other end of the side pulling core is connected with a driving structure for driving the side pulling core to move back and forth; the driving structure comprises a sliding block and a sliding block connecting block connected with the sliding block, and one end of the sliding block connecting block is connected with a driving source; and a locking block is arranged below the sliding block, and an ejection spring is arranged below the locking block. According to the structure, the problem that interference of mold opening of the machining side pulling core of an installation hole of the handle lever occurs can be effectively solved, structural design is ingenious, machining precision is high, and the structure can be widely applied to the field of handle lever machining.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to an automobile handle bar molding structure. Background technique [0002] As a common part of the car, the handle rod includes a round rod part and a mounting part at one end. In order to improve the integrity, the existing handle rods are all injection molded at one time, thereby improving production efficiency. In order to meet the design requirements, it is necessary to open a mounting hole on the mounting part of the handle rod, such as figure 1 shown. This structural design needs to extend the core of the forming installation hole into the molding cavity after the mold is closed. After the injection molding is completed, the core of the forming installation hole needs to be withdrawn first before the mold can be opened. Therefore, it is necessary to design a set of structures for forming the above-mentioned mounting holes. Contents of the invention [0003] T...
