Description

Technical Field

[0001] The utility model relates to the technical field of plastic blister moulds, in particular to a common mould frame structure for plastic blister moulds. Background Art

[0002] The blister process is a plastic processing technology. The main principle is to heat and soften the flat plastic hard sheet, vacuum it to the mold surface, and then cool it to form it. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. During the blister process, the sheet is softened by heat, and vacuum is drawn to the surface of the core to form it in the cavity. However, when the mold frame structure of the existing blister mold is actually used to replace the mold, the mold frame needs to be replaced at the same time, which results in high labor intensity, takes up a lot of time, and affects production efficiency.

A movable arm is provided in the movable inner cavity, and a pressure spring is press-fittedly connected to the bottom of the movable arm, and a sliding rod extending up and down is slidably connected in the top wall of the movable inner cavity. The bottom of the sliding rod is fixedly connected to the movable arm, and the top of the sliding rod is rotatably connected to rollers symmetrically arranged on the left and right. An inclined convex portion is fixedly provided on the top of the movable arm, and a telescopic motor is fixedly provided on the top wall of the movable inner cavity. A telescopic control screw is dynamically connected to the telescopic control screw, and a wedge-shaped top sliding block for press-fitting with the inclined convex portion is threadedly connected on the telescopic control screw.

[0005] According to a further technical solution, a heating plate is provided in the lifting heating mold.

[0006] According to a further technical solution, the left and right sides of the fixing frame are fixedly connected to the base via support rods.
