Description

Technical Field

[0001] The utility model relates to the technical field of switch shell production, in particular to a four-button shell mold for a ceiling light switch. Background Art

[0002] As a lighting appliance, ceiling lights are mainly used to provide lighting functions. They can be used in various environments such as homes and commercial places. For example, ceiling lights are installed close to the roof and use fluorescent lamps or LED patches as light sources to provide a wide range of lighting effects. They are widely used. For multi-color adjustable ceiling lights, a multi-key switch structure is generally used for control. The shell structure of the multi-key switch is usually injection molded using an injection molding machine in conjunction with an injection mold.

[0003] The existing injection mold for ceiling light switch shells has the following disadvantages when used: the existing injection mold for light control switch shells usually uses a large mold with multiple sets of mold cavities built in, and multiple switch shells can be produced simultaneously after a single stroke. Although it has the characteristics of high efficiency, when a group of mold cavities inside the mold are worn or aged, affecting the product molding quality, the mold can usually only be replaced as a whole, which has a high maintenance cost. For this reason, we propose a four-button shell mold for ceiling light switches. Utility Model Content

[0004] The main purpose of the utility model is to provide a four-button housing mold for a ceiling light switch. By improving the mold structure, it can not only ensure the injection molding production efficiency, but also reduce the maintenance and replacement costs of the mold, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

During the injection molding production process, each group of cylinders is controlled by a preset program to operate in sequence and in an orderly manner. When the cylinder is running, the movable mold is driven to move through the fixed frame to realize the opening and closing control of each group of molds, thereby realizing continuous production.

[0008] Furthermore, a mold cavity is opened inside the fixed mold, and a mold core is provided at the end of the movable mold, which corresponds to the position of the mold cavity and is inserted into the mold cavity; when the mold is closed, the mold core on the movable mold side is inserted into the mold cavity of the fixed mold, and after the mold is closed, injection molding is performed to obtain a qualified light-controlled switch housing.

[0009] Furthermore, a melt valve is installed inside the feed pipe on one side of the mounting seat, and the top of the melt valve extends to the top of the mounting seat; the melt valve can be used to control the opening and closing of the injection molding pipe supply inside each group of movable molds.

[0010] Furthermore, the brackets are provided with mounting holes for conveniently screwing in fasteners; the mounting hole structure facilitates the use of fasteners to fix the brackets to the surface of the mounting body.

The movable mold structure adopts multiple groups of independent structures installed side by side. The cylinder controls each group of movable molds to operate in sequence and in an orderly manner. When the movable mold moves, the corrugated rubber sleeve is continuously compressed and expanded, and the piston tube moves along the outer periphery of the feed tube, which can not only provide stable feeding, but also does not affect the mold opening and closing process. When the injection molding is carried out, the cylinder controls the movement of the movable mold to close the mold with the fixed mold at the corresponding position. After closing the mold, the melt valve is opened, and the feed tube feeds material to the inside of the injection tube through the piston tube for injection molding. The feed is stopped after the injection molding is completed. The material is discharged and the mold is opened. The multiple groups of movable molds located on the surface of the mounting seat operate in sequence to realize continuous injection molding production.
