Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding technical field, concretely relates to a kind of automobile charging pile cover plate injection molding mould. BACKGROUND

[0002] With the development of new energy vehicles, more and more supporting charging piles are needed to display relevant information for easy use, so the cover plate of the charging pile is usually provided with reverse buckle holes, through holes and the like to facilitate the installation of electronic indicators such as indicator lights. Figure 1 Disclosed is an existing automobile charging pile cover plate 1, which is provided with a square reverse buckle hole 2 extending obliquely on the front surface. The extension direction of the square reverse buckle hole 2 forms a certain angle with the extension direction of the automobile charging pile cover plate 1. When the square reverse buckle hole 2 is formed by using a conventional inclined ejector pin, it is difficult to smoothly release the buckle after ejection, and forcibly pulling it out can easily deform or damage the automobile charging pile cover plate 1, resulting in a high rejection rate. If a material taking mechanism is additionally provided to take out the material obliquely after ejection by the inclined ejector pin, the complexity of the structure of the injection molding mold will be increased, the cost will be high, and the subsequent material taking action will also consume time, which will reduce the injection molding efficiency.

The upper end of the oblique core pull 60 passes through the top surface of the mold core 30 and extends upward to form a square inverted hole 2 on the front of the automobile charging pile cover 1. The lower end of the oblique core pull 60 is connected to the upper end of the vertical core pull 50 through an obliquely arranged concave-convex matching structure. When the pad 40 moves downward, the vertical core pull 50 follows and changes the direction of the downward movement power through the concave-convex matching structure and transmits it to the oblique core pull 60, so that the oblique core pull 60 moves obliquely and its upper end is retracted into the oblique groove 72 to achieve disengagement. The disengagement is smooth and no additional material-retrieving mechanism is required, so that the structure of the injection mold is simple, the cost is low, and the production efficiency is high.
