[0002] In the process of manufacturing light bulbs, it is usually necessary to process the light bulbs into a certain shape and size. Light bulb molding refers to processing the glass tube into a light bulb shell with a certain shape and size. Existing equipment usually puts the prefabricated glass tube into a molding machine and processes it by vacuum suction and blowing or pressure blowing to deform it into a light bulb shell with a certain shape and size.
[0003] However, the existing molding device is not convenient for stably clamping the glass tube when molding the glass tube, and the glass tube is easy to move during the molding process. In addition, the existing molding device is not convenient for driving the molded glass tube to rotate briefly. The molded glass tube is easy to stick to the mold block and break, resulting in poor molding effect of the glass tube. Utility Model Content

[0006] As a preferred technical solution of the utility model, the clamping assembly includes a limiting plate, the two limiting plates are respectively fixedly connected to the two sides of the limiting frame, the two limiting plates are slidably connected to sliding blocks, the two sliding blocks are slidably connected to sliding extrusion blocks, the bottom ends of the two mold blocks are fixedly connected to extrusion rods, and the extrusion rods are in contact with the sliding blocks.
[0007] As a preferred technical solution of the utility model, the toggle assembly includes a toggle rod, the two toggle rods are respectively fixedly connected to the two sliding extrusion blocks, the two sliding blocks are fixedly connected to limit blocks, a tension spring is connected between the toggle rod and the limit blocks, the two extrusion rods are slidably connected to sliding toggle blocks, and a compression spring is connected between the sliding toggle block and the extrusion rod.
[0008] As a preferred technical solution of the utility model, it also includes a sealing plate, two of the sealing plates are fixedly connected to the two abrasive blocks respectively, and the sealing plates are made of rubber.
[0009] Compared with the prior art, the utility model has the following advantages: 1. The utility model drives the arc rail to rotate through a motor, and the rotation of the arc rail will drive the two limit slide bars, the mold block and the sealing plate to move in a direction close to each other. The two mold blocks move to fit each other, and the two sealing plates are clamped between the two mold blocks, so that the two mold blocks fit more closely. When the mold block moves, the two sliding blocks and the sliding extrusion block are pushed to move in a direction close to each other through the two extrusion rods.
