Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle moulds and relates to a multi-slant top combined demoulding mechanism for left and right decorative parts of an electric vehicle. Background Art

[0002] An electric bicycle is a mechatronic personal transportation tool that uses a battery as an auxiliary energy source and is based on an ordinary bicycle. It is equipped with a motor, controller, battery, handlebars and other operating components and a display instrument system. A plastic decorative panel is usually installed at the front end of the electric bicycle. The existing decorative panels are directly injection molded by an injection mold and then ejected by an ejector.

[0003] When there are undercuts, buckles and other structures inside the decorative panel structure, a slanted top structure is generally used for demolding. The slanted top design has a relatively simple process and low cost. The slanted top is pushed forward at a certain angle. After a certain forward stroke, the position of the buckle is out of contact with the inner side of the plastic, so that the product can be smoothly taken out. The traditional slanted top rod body is guided and supported by a guide limit block when the slanted top rod moves. The guide limit block will directly rub and slide with the outer wall of the slanted top rod. After long-term use, the outer wall and the slide groove of the slanted top rod will be worn, which will affect the strength of the slanted top rod and the guiding accuracy. However, the existing slanted top rods are all arranged in one piece. Therefore, the slanted top rod structure can only be replaced as a whole. In this case, the use cost is relatively high, and improvements need to be made in this regard. Summary of the invention
