Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: when the workpiece of the automobile small door is poured and the mold is opened, since the transverse reinforcement at the reinforcing net needs to use the inclined roof to separate the workpiece from the mold, the restrictive conditions of the common inclined roof device are relatively strict. If there are too many, it is easy to cause the workpiece to be unable to be ejected smoothly

The invention relates to the technical field of precision mold injection molding, in particular to a mold for producing a fuel filler cover. The mold comprises a front mold and a rear mold. The frontmold comprises a movable mold and a fixed mold. The fixed mold is fixedly connected with an injection molding machine. The movable mold abuts against the fixed mold. The movable mold is slidably connected with the fixed mold. An ejection device is arranged between the movable mold and the fixed mold. The rear mold comprises a movable mold core, a fixed plate and a connecting plate. The movable mold core is arranged close to the front mold. The fixed plate is arranged on the side, far away from the front mold, of the movable mold core. The connecting plate is arranged between the movable mold core and the fixed plate. The two ends of the connecting plate are fixedly connected with the movable mold core and the fixed plate. Elastic assembles are arranged between the movable mold core and thefixed plate. An ejector plate is arranged between the movable mold core and the fixed plate. The movable mold core is internally provided with an ejector pin which is slidably connected with the movable mold core. A connecting block is arranged between the ejector pin and the ejector plate. The connecting block is fixedly connected with the ejector plate. A sliding assembly is arranged between the connecting block and the ejector plate. The mold for producing the fuel filler cover has the effect that a workpiece can be taken out from the mold conveniently.
