Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp moulds, in particular to a plastic vehicle lamp mould. Background Art

[0002] Car lights are tools for illuminating the road when vehicles are driving at night, and are also tools for issuing various vehicle driving signals. Car lights are generally divided into headlights, taillights, turn signals, etc. Car lights are made of plastic. At the same time, in order to improve the efficiency of car light preparation, mold injection molding is used to drive the car lights to be prepared and formed.

[0003] Among the publicly authorized patents, the Chinese patent with the patent number "CN202110925847.0" discloses a headlight control box and a mold for manufacturing the headlight control box, which belongs to the technical field of automotive parts. The length direction of the protrusion on each side wall extends along the length direction of the side wall. The shell is ejected and cut out by the ejector pin on the movable mold, which eliminates the subsequent polishing process of the inner cavity of the shell groove, improves work efficiency and reduces production costs;

[0004] In the above device, after the mold is prepared and formed, it is necessary to process the material. A common mold is provided with an ejector pin, which pushes the molded headlight out from the inside of the mold, and then drives the mold to be demolded. However, when the ejector pin pushes the mold to demold, the ejector pin will cause damage to the mold. At the same time, a flip mold is used to drive the model to automatically fall off under the action of gravity. However, during the mold preparation process, in order to ensure the service life of the mold, the mold is usually made of steel material, and the weight of the steel material is heavy, so when controlling the flipping and demolding of the mold, the flipping mold consumes a lot of physical strength of the staff. For this reason, we propose a plastic headlight mold. Utility Model Content

[0007] Preferably, the outer portion of the disc is circular, the rotating handle extends to the side of the side mounting plate, and the rotating handle is installed on both sides of the side mounting plate.

[0008] Preferably, the upper mold is sleeved on the upper end of the lower mold, the positioning rod passes through the upper mold, and the mold positioning nut and the positioning rod are threadedly moved relative to each other, while the lower end of the mold positioning nut is in contact with the outside of the upper mold.

[0009] Preferably, the inner side of the grouting hole is communicated with the mold positioning groove, and the shape of the vehicle lamp is the same as the shape of the mold positioning groove.

[0010] Preferably, the threaded rod is kept parallel to the horizontal plane, and the two sets of mold support sleeves are movably sleeved on both sides of the lower end of the lower mold.

[0011] Preferably, the auxiliary connecting plate and the auxiliary sliding rod are mutually sleeved and restricted, and the oblique telescopic rod is installed between the processing table and the mold support sleeve.

[0012] Compared with the existing plastic headlight mold, the utility model has the following beneficial effects:

[0013] 1. The plastic headlight mold is installed on the inner side of the disc by rotating the lower mold, and then the lower mold drives the upper mold to be suspended in the air, and the rotating handle is turned to drive the mold to flip. When the lower mold is too heavy and it is difficult to demold the lower mold, the lower mold can be turned by turning the rotating handle, thereby improving the convenience of demolding the headlight.

[0014] 2. The plastic headlight mold pushes the mold support sleeve to move inward by rotating the threaded rod. At the same time, the mold support sleeve can provide auxiliary support for the position of the side of the lower mold. An oblique telescopic rod is installed at the lower end of the mold support sleeve.
