Description

TECHNICAL FIELD

[0001] The utility model belongs to mould technical field relates to a kind of electric vehicle LED car lamp mask mould inclined inner extraction demoulding mechanism. BACKGROUND

[0002] Electric vehicle LED car lamp mask is generally formed by injection molding. Due to the need of installation, the side groove will be needed on the car lamp mask to facilitate subsequent assembly and connection. After the existing electric vehicle LED car lamp mask mould is injected, the product is generally ejected by using a one-way ejection structure. Such ejection structure is prone to sticking with the product during ejection, and the side groove structure of the mask will be damaged during ejection, affecting the demolding efficiency and product quality. Therefore, it is urgent to design an electric vehicle LED car lamp mask mould inclined inner extraction demoulding mechanism that can overcome the above defects.

[0003] In order to overcome the deficiencies of the prior art, people have continuously explored and proposed various solutions. For example, a car lamp mask forming die [application number: 201410438418.0] is disclosed in Chinese patent, which includes a movable die and a fixed die. The fixed die includes a fixed die plate with a female die on the inner side. The movable die includes a bottom plate, a movable die plate and a long oblique ejector. The bottom plate and the movable die plate are arranged along the horizontal direction. The movable die plate has an inclined guide hole. The long oblique ejector passes through the guide hole along the inclined direction, and the two ends of the long oblique ejector extend out of the movable die plate. The bottom plate is fixed with an inner extraction slide along the vertical direction of the bottom plate. When the movable die and the fixed die are closed, the long oblique ejector, the inner extraction slide and the female die form a cavity for forming the car lamp mask. The movable die plate is provided with an ejection mechanism for driving the long oblique ejector to slide relative to the movable die plate along the inclined direction to eject the formed car lamp mask. However, after the injection is completed, the product is still prone to sticking during ejection, and the side groove structure of the mask will still be damaged during ejection, which has the defects of general demolding efficiency and product quality.

The first forming insert 4 has a headlight cover forming protrusion 6, and the second forming insert 5 has a headlight cover forming cavity 7.
