Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp production, in particular to a vehicle lamp mould which is easy to clean. Background Art

[0002] Car lights are tools for vehicles to illuminate the road at night, and are also tools for issuing various vehicle driving signals. Car lights are generally divided into headlights, taillights, turn signals, etc. They are one of the important components of a car. Injection molds and injection molding equipment are generally used in their production process for injection molding.

[0003] Existing headlight production molds have the following disadvantages during use: After the headlight injection mold is demolded and the material is removed, the inside of the mold cavity needs to be cleaned to avoid residual waste residue that affects the subsequent molding quality of the headlight. The cleaning method is generally to manually hold the blowpipe to blow clean the inside of the mold cavity, which is inefficient and increases the amount of manual labor. Therefore, we propose a headlight mold that is easy to clean. Utility Model Content

An air intake pipe connected to an external high-pressure air supply device is provided on one side of the surface of the mold body, and the discharge end of the air intake pipe is connected to the movable tube through the air supply pipe.

[0007] Furthermore, it also includes an auxiliary mechanism, an auxiliary mechanism is arranged inside the installation groove, the auxiliary mechanism includes a rotating shaft and a limit plate, a rotating shaft is installed at one end of the installation groove and is movably connected to the limit plate through the rotating shaft, and the air supply pipe is attached to the surface of the limit plate; the interior of the installation groove is connected to the limit plate through the rotating shaft, and the limit plate can be deflected within a certain angle under the action of the rotating shaft, and the air supply pipe is tied together with the limit plate through a strap. When the mold bodies are closed, the limit plate moves toward the inside of the installation groove and drives the air supply pipe to be retracted into the installation groove, which can avoid the problem of the air supply pipe being squeezed by the mold body.

[0008] Furthermore, a spring is installed inside the sleeve and is connected to the end of the insertion rod through the spring; the spring plays a connecting role, so that the insertion rod can drive the movable tube to be automatically ejected after the mold is opened.

[0009] Furthermore, a solenoid valve for controlling the opening and closing of the pipeline is installed at the connection between the air intake pipe and the air supply pipe; the opening and closing of the pipeline can be controlled by the solenoid valve.

[0010] Furthermore, a binding strap is connected between the surface of the limiting plate and the surface of the air supply pipe; the limiting plate and the air supply pipe are bound and fixed together by the binding strap.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the mold body is installed in the injection molding equipment and the car light is injection-molded through the internal mold cavity. A mounting groove is opened at the top of the mold body, and a movable tube with adjustable position is provided inside the mold body. During the mold closing and injection molding process, the movable tube is squeezed and collected into the mounting groove, which does not affect the mold closing and injection molding. When the molding is completed and the mold is opened, the insert rod is pushed out and drives the movable tube to move out. After the car light is taken out, the air intake pipe and the air supply pipe are connected, so that the external high-pressure air flow passes through the movable tube and is ejected from the nozzle to the surface of the mold body, and the mold cavity surface is subjected to high-pressure blowing treatment to remove residual waste residue, thereby ensuring the subsequent car light injection molding quality, realizing automatic cleaning processing, and reducing manual labor; the interior of the mounting groove is connected to the limit plate through a rotating shaft. The limit plate can be deflected within a certain angle under the action of the rotating shaft. The air supply pipe is tied together with the limit plate by a strap. When the mold bodies are closed, the limit plate moves toward the inside of the mounting groove and drives the air supply pipe to be collected into the mounting groove, which can avoid the problem of the air supply pipe being squeezed by the mold body.
